    Description: Effects of S. cerevisiae on immune parameters of the L. vannamei after 14 days of S .cerevisiae feeding were evaluated in this study. For this purpose a total of 300 pieces of shrimp with an average weight of 30 to 35 grams were selected from a pool shrimp Abadan CHOEBDEH. After making sure the health, absence of necrosis on the surface of the body, cuts antenna, shrimp were transferred to the center of BANDAR IMAM Research Station. Adaptation was carried out for 3-5 days. After the adaptation, shrimps were screened for virus (WSSV, TSV, MBV, HPV, YHV, BP, IHHNV and IMNV) and vibrio bacteria.After screening shrimps divided to two groups with three replication (including 50 pieces of shrimp in triplicate). The experimental diet has the commercial shrimp composition ,but 2 g of S. cerevisiae substituted 2 g of fish meal. Shrimp of first group (T1) for 14 days with food containing nutritional yeast and shrimp in second group (T2) were fed with normal diet without yeast. After 14 days Immune Factors and survival rates in both groups were evaluated. The results showed that the relative survival rate between the two groups showed no significant difference. But Immune Factors (THC, TPP, PO, POD and SOD) in the treatment fed yeast (T1) compared to control treatment (T2) showed a significant increase. In conclusion these results suggest that the increased survival rate and resistance of shrimp after S. cerevisiae consumption occurs through immune modifications, such as increases in THC, TPP, SOD, SOP and PO activity.

    Isolation and long-term culture of neural stem cells from Acipenser persicus (Borodin, 1897) (2018)
    Details
    Publication Date: 2021-05-19
    Description: In the present study, an in vitro brain cell culture was developed from neural cells of Persian sturgeon (Acipenser persicus). The tissue samples collected from the anterior, middle and posterior regions of the brain were cultivated separately in DMEM/F12 medium supplemented with 15% fetal bovine serum, antibiotic and antimycotic. The medium was refreshed every 3 days. The cells became confluent after about 3 weeks from the initial time of seeding. The cultured cells from the posterior part of the brain showed high potential of proliferation as they had been passaged 16 times in more than 11 months. To determine optimal temperature, the brain cells were incubated at four temperatures including; 20, 22, 25 and 28°C. The best cultivation temperature was obtained at 25°C. The cultured cells from posterior part of the brain were cryopreserved successfully and the survival rate was 70% after thawing. Immunocytochemistry using antibody against nesting showed that some cells were immunopositive for nesting. Finally, these results suggested that cell cultures from posterior part of the Persian sturgeon brain with high proliferation capacity can be useful for research on brain cells in A. persicus in the future.

    Growth and feed utilization of goldfish (Carassius auratus) fed graded levels of brewers yeast (Saccharomyces cerevisiae) (2018)
    Details
    Publication Date: 2021-05-19
    Description: In this study, a feeding trial was conducted to examine the potential of replacing fish meal with brewers yeast in practical diet of goldfish (Carassius auratus). Five isoproteic (37% CP) and isocaloric (3350 kcal/kg) diets were formulated to contain graded levels of brewers yeast. Fish meal protein was replaced by 0%, 15%, 25%, 35%, and 45% of yeast. Each diet was randomly allocated to triplicate groups of 20 fish (initial average weight of 0.56 g fish-1) in glass aquarium (65L). Fish were fed three times per day to apparent satiation for 84 days. At the end of the experiment, weight gain, specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER), condition factor (CF), survival rate (SR), hepatosomatic indices (HSI) and body composition of goldfish fry were determined. According to the results, weight gain, SGR, FCR and PER of fish fed the diet including yeast replaced 35% of the fish meal were better than those of fish fed the other diets. There were no significant differences in SR and HSI values among fish fed diets (p〉0.05). However, CF among fish fed the experimental diets was significantly differ (p〉0.05). Whole body composition was similar among fish fed different diets. The optimal replacement level of fishmeal protein by brewers yeast was determined by second-order polynomial regression to be (y= 2, 2237- 0,0004x2 + 0,0279x; R² = 0,9977) 34.875%, on the basis of SGR.

    The probiotic effects of dietary inactive yeast Saccharomyces cerevisiae var. ellipsoideus on growth factors, survival, body composition and intestinal microbiota of Beluga juvenile (Huso huso) (2017)
    Details
    Publication Date: 2021-05-19
    Description: The probiotic effects of inactive yeast, Saccharomyces cerevisiae var. ellipsoideus was studied on growth performance, survival and intestinal microbiota of beluga juveniles (Huso huso). The study was done in complete randomize design that included feeding of beluga juveniles with diets supplemented with 0 (control), 1, 2 and 5% yeast (4 treatments with 3 replicates). Beluga juveniles (11.40±0.56g) were randomly allocated in 12 oval tanks at a density of 35 fish per tank and triplicate group were fed with experimental diets. At the end of the trial, growth factors (final weight, weight gain, SGR, CF) as well as feed conversion ratio (FCR), body composition (protein, lipid, ash, moisture) and intestinal microbiota (total viable bacteria and Lactobacillus spp. levels) were determined. Our results confirmed that juveniles fed on diet supplemented with 5% S. cerevisiae var. ellipsoideus had significantly higher final weight, weight gain, specific growth rate (SGR) and lower food conversion ratio compared to control and 1% treatment (P〈0.05). However, there were no significant differences between SGR of 5 and 2% yeast treatments (P〉0.05). The study of body composition showed no significant difference between treatments (P〉0.05). Total viable bacteria and Lactobacillus spp. count were significantly higher in 5% treatment compared to control (P〈0.05). However, there was no significant difference between Lactobacillus spp. levels in 5 and 2% treatments (P〉0.05).

    The probiotic effects of dietary Saccharomyces cerevisiae and Aspergillus niger on the growth and some immunity factors of cultured juvenile beluga sturgeon (Huso huso) (2017)
    Details
    Publication Date: 2021-05-19
    Description: This study was conducted to evaluate the effects of dietary autochthonous Saccharomyces cerevisiae and Aspergillus niger on the growth performance, survival rate, ammonia excretion, immune response and the intestinal microbiota of juvenile beluga sturgeon (Huso huso). Beluga juveniles with average (±SD) weight of 31.8±2.81 g were randomly allocated into 12 oval tanks (1000 l) at a density of 30 fish per tank and triplicate groups and were fed either with a basal control diet (no supplemented with probiotic) or with the basal diet supplemented with S. cerevisiae and A. niger (2×106 , 4×106 and 6×106 cells g-1 ). After 8 weeks of feeding on the experimental diets, growth factors, survival rate, ammonia excretion, immunity parameters and gut microbiota were measured. The results indicated that dietary supplementation of 6×106 (cells g-1 ) S. cerevisiae and A. niger significantly improved growth indicators, survival rate, immune parameters and ammonia excretion compared to the control treatment. Additionally, total autochthonous intestinal fungus probiotic and Lactobacillus spp. counts were affected by dietary treatment. The results showed that dietary supplementation of S. cerevisiae and A. niger (6×106 cells g-1 ) had positive effects on growth and immunity factors in cultured juveniles beluga.

    Dietary effect of celmanax® on growth factor, intestine histology and yersiniosis resistance in rainbow trout (Oncorhynchus mykiss) (2018)
    Details
    Publication Date: 2021-05-19
    Description: This study aims to analyse the effect of complementing the rations of breeding rainbow trout with different concentrations levels of celmanax® prebiotic, which contains Saccharomyces cerevisia associated compounds with Mannan-oligosaccharide on the growth indexes and histologic effects of the prebiotic and the gastrointestinal tract and also measuring of the resistance of breeding fishes fed with this prebiotic in infection to the yersiniosis. Three concentration levels of prebiotic (0, 0.1, 0.5 and 1 %) were mixed into pellets. The fish (19.08±1.45gr) were fed a supplemented commercial diet for 60 days in four treatments and each treatment with three replications. Also, on day 60 of study, the Yersinia ruckeri bacterium was injected empirically into all of our groups. This study’s results showed that complementing rainbow trout rations with different concentrations level of celmanax® (P〈0.05) increased the final weight, daily growth rate, specific growth factors, Food efficiency index and feed conversion so significantly. Histopathologic results also showed significantly changes namely, increase in the thickness of the mucous membranes, length of the villi and the muscle layer in the gastrointestinal tract of the fish which were fed with prebiotic in comparison with the control group (P〈0.05). The results also showed that those fish that where fed with prebiotic had significantly lower death rates compared to the control group (p〈0.05). According to these findings, it can be concluded that different concentrations level of celmanax® prebiotics could be used in order to increase the growth, histological changes in the gastrointestinal tract and rainbow trout resistance.

    Description: Galveston Bay, Matagorda Bay, San Antonio Bay, Aransas Bay and South Bay areas were sampled at a total of nineteen stations to determine the population characteristics and fluctuations of oysters on the Texas coast. Population samples taken at monthly intervals from these stations showed heavy spat setting occurred in June 1962 and continued in moderation through December 1962. Survival of spat and seed class oysters ranged from moderate in Galveston Bay to excellent in the lower coastal bays. No extensive natural moralities were noted in any of the bay areas and the number of market-sized oysters increased in nearly all the bays. Dermocystidium marinum incidence maintained a high level, but no moralities were associated with the fungus. Oyster populations in Aransas Bay have recovered from the 1959 die-off and are once again approaching an overcrowded conditions for lack of harvesting. Artificial reefs, built in Aransas and Matagorda Bays, have been extremely successful and have attained the characteristics of natural oyster reefs.

    Description: Postlarvae were found entering Aransas Bay in appreciable numbers in the spring of 1963. Late post-larval and early juvenile stages of brown shrimp, Penaeus aztecus, were found in tertiary bays in April. White shrimp, P. setiferus were found in May and June. Brown shrimp grew about 0.8 mm per day, while white shrimp grew about 1.1 mm per day. The first wave appeared to be smaller than latter waves. Small brown shrimp were found moving through the inshore Gulf in large numbers in June and July. White shrimp reached a larger size in the bays in June and July. White shrimp reached a larger size in the bays and supported a large commercial bay fishery. Late fall waves of white shrimp left the bays at a smaller size (probably to escape low water temperatures). Preliminary data indicate the 1963 shrimp landings increased 25% over 1962 landings.

    Description: In spring, the growth of brown shrimp, Penaeus aztecus, in Texas bays, including Galveston Bay, was delayed by cold water. Low salinity patterns of upper coastal bays confined the young to more saline lower regions of estuaries. The gulfward migration began in late May. By July most had left the bays. Heavy rainfall and runoff may have been beneficial to white shrimp, Penaeus setiferus. They were abundant in samples and over 12 million pounds were landed commercially.

    Description: Sand seatrout (Cynoscion arenarius Ginsberg) were studied in the Galveston Bay area to provide information on seasonality, population composition, food items, growth, and spawning. Tagging efforts resulted in 518 tagged fish and a return of 16 tags during the 1968-70 period. Tag recovery data suggest a migration from the upper bay to the lower bay and Gulf waters in December and return in March. Electrophoretic analysis of multiple hemoglobin protein types were studied from 96 sand seatrout blood samples. Five protein types were observed without discernible differences that could be attributed to population heterogeneity. Analysis of stomach content revealed crustacea and fish as primary food items. Gonad development stages indicate a spawning period from March through August.

    Description: This report deals with the growth, seasonal abundance, and movement of brown shrimp, Penaeus aztecus, and white shrimp, Penaeus setiferus, in the coastal bays of Texas in 1965, including Galveston Bay. Young brown shrimp were abundant in the spring. Apparently, unfavorable bay conditions forced the young to enter the Gulf at an unusually small size. The fairly high brown shrimp population level in the estuaries after June 1 was indicative of a long emigration period and a strong year-class. White shrimp samples were small in the summer, but a large group was recruited to the population in the fall. The brown shrimp commercial catch in the spring (from major bays) increased 75% over 1964. White shrimp catches were small in August and September, but increased sharply in late fall. The total 1965 Texas shrimp landings, which nearly equaled the large 1960 catch, were over 48 million pounds, headless. Annual brown shrimp landings increased 31% from 1964, but white shrimp landings decreased 21%.

    Description: Plankton samples from the Aransas Bay area indicated that the post larvae brown shrimp (Penaeus aztecus) immigration peak was reached in March. Sampling in the bays revealed the presence of a large wave of brown shrimp in the spring. In the shallow tertiary bays and along the shore of large bays brown shrimp grew slowly in April and movement to the open water of larger bays was delayed. As the waters warmed growth was rapid and the shrimp began their gulf ward movement on schedule. Samples taken in the inshore Gulf off the Lower Laguna Madre contained large numbers of brown shrimp in May. The samples from the Gulf off Port Aransas indicated that the majority of this species left the Aransas Bay area in June. Shrimp samples from the bays indicated the presence of a large 1964 white shrimp year class. This was confirmed by large commercial catches in the late summer and early fall. Small white shrimp were found in the Gulf in September off the lower coast. In January this species was found in abundance off Port Aransas, but not off Galveston. Brown shrimp commercial landings were somewhat disappointing, however, white shrimp landings were greater than landings reported in 1963.

    Description: A moderate set of spat was observed throughout the bay in June and July. A light spat set also occurred in September and October on reefs in the middle and lower bay areas. The fall set was not found in upper Trinity Bay. The majority of the oysters were less than three years of age although remnant population of oysters over five years old were occasionally found. Some oysters reached legal size at two and one-half years of age but most of the market sized oysters were over three years old. The incidence of the fungus organism, Dermocystidium marinum, increased in late summer and early fall. As a result, moralities among the older oysters were expected to increase. However, no unusual moralities were noted by the end of the sample period. The 1961-62 oyster harvest was generally confined to Todd's Dump and Hanna's Reef. Oysters were good in quality but not exceptional. During the 1962-63 season oyster boats spread out and worked several reefs which had been unproductive in past years. Both the quality and quantity of oysters were better than in previous years.

    Description: In spring, samples were taken with bar-seines and trawls from Sabine Lake, Galveston Bay, Matagorda Bay, Aransas Bay, and the Lower Laguna Madre to study brown shrimp (Penaeus aztecus) growth, movements, seasonal abundance trends, and environmental needs. The shrimp was abundant in samples from Galveston Bay, Aransas Bay, and the Lower Laguna Madre. Slow growth of juveniles during April in upper coastal bays was attributed to low temperature. Many, however, were 70 to 80 mm long by late May, because growth accelerated as bays warmed.

    Description: Penaeus aztecus, brown shrimp, arrived at the tertiary bays in early April, but grew slowly. In May growth accelerated and emigration from the bay began in June when the shrimp were less than 90 mm long. A second wave of brown shrimp arrived in August. White shrimp, P. setiferus, arrived at the tertiary bays in June. This group of shrimp was followed by two smaller groups in August and October. Brown shrimp were found in Sabine Lake in May. The 1964 white shrimp were found in mid-June. In the fall a second wave of white shrimp was observed. Commercial brown shrimp landings reached a peak in July and August, but fell sharply after September. White shrimp production was high.

    Description: An experiment was conducted to study the effect of different feeds on growth survival and production of African catfish (C. gariepinus) in six cemented tanks (3m² each) over a period of 120 days. Three different feeds namely Feed A (Saudi-Bangla fish feed, 33.43% protein), Feed B (formulated feed, 40.12% protein) and Feed C (chicken raw intestine, 59.58% protein) were applied to treatments I, II and III respectively. Each of the tanks was stocked with 24 fry with mean initial body weight of 2.56±0.06 g. Feeds were supplied to the fish ad-libitum daily in two instalments. Significantly highest weight gain was obtained in treatment III, however, survival rate was low compared to other treatments. The feed conversion ratio (FCR) values ranged from 2.52-6.4. Survival rate of fish varied between 83 and 96%. Treatment II yielded the highest (5000 kg/ha/120 days) production with the highest survival rate of fish. On the basis of survival rate and production, it is suggested that the formulated feed (Feed B) is suitable for the culture of C. gariepinus in cemented tanks.

    A simple approach for the estimation of food consumption from growth rates at different environmental conditions and its application to juvenile cod (Gadus morhua L.) of a fjordic sea loch on the west coast of Scotland (2021)

    Description: AbstractGrowth and condition of fish are functions of available food and environmental conditions. This led to the idea of using fish as a “consumption sensor” for the measurement of food intake over a defined period of time. A bio-physical model for the estimation of food consumption was developed based on the von Bertalanffy model. Whereas some of the input variables of the model, the initial and final lengths and masses of a fish and the temperature within the time period considered can easily be measured, internal characteristics of the species have to be determined indirectly. Three internal parameters are used in the model: the maintenance consumption at 0°C, the temperature dependence of this consumption and the food efficiency, the percentage of the ingested food utilized. Estimates of the parameters for a given species can be determined by feeding experiments. Here, data from published feeding experiments on juvenile cod, Gadus morhua L., were used to validate the model. The average of the relative error for the food intake predicted by the model for individual fish was about 24 %, indicating that fish used the food with different efficiencies. However, grouping the fish according to size classes and temperature lowered the relative error of the predicted food intake for the group to typically 5 %. For a group containing all fish of the feeding experiment the relative prediction error was about 2 %.ZusammenfassungWachstum und Kondition der Fische sind von der verfügbaren Nahrung und von Umweltbedingungen abhängig. Dies führte zur Idee, Fisch als „Konsum-Sensor“ für die Messung der Nahrungsaufnahme über einen definierten Zeitraum zu verwenden. Auf Grundlage des von Bertalanffy-Modells wurde ein bio-physikalisches Modell zur Schätzung der Futteraufnahme entwickelt. Während einige der Eingangsgrößen des Modells leicht gemessen werden können (Anfangs- und Endlänge und -körpermasse der Fische und die Temperatur innerhalb des betrachteten Zeitraum), können interne Parameter der betrachteten Art nur indirekt bestimmt werden. Drei interne Parameter werden in dem Modell verwendet: Die Erhaltungskonsumtion bei0° C, die Temperaturabhängigkeit dieser Rate und der Wirkungsgrad der Nahrung (der Anteil der Nahrung ,der aufgenommen und verwendet und nicht ungenutzt wieder ausgeschieden wird). Die Modellparameter für eine bestimmte Art können durch Fütterungsversuche bestimmt werden. Um das Modell zu validieren wurden Daten aus veröffentlichten Fütterungsversuchen mit juvenilen Kabeljau (Gadus morhua L.) verwendet. Modell und Wirklichkeit weichen in der Regel voneinander ab. Der durchschnittliche relative Fehler der durch das Modell vorhergesagten Nahrungsaufnahme betrug für Einzelfische etwa 24%, was darauf hinweist, dass einzelne Fisch die Nahrung mit unterschiedlichen Wirkungsgraden verwerten. Allerdings senkte die Gruppierung der Fische nach Größenklassen und Temperatur den relativen Vorhersagefehler für die Nahrungsaufnahme der Gruppe auf etwa 5%. Für alle Fische im Fütterungsversuch ist der relative Vorhersagefehler etwa 2%.

    Description: Age, growth and reproduction of H. kelee were studied, and a brief description of its fishery in Maputo Bay (Mozambique) is given. Most material was collected from gill net fisheries during 1977-1980, but some was taken from shrimp trawlers operating in the same area during 1980-1981. Main spawning takes place during October-January with a peak in December. There is also some evidence that spawning takes place during June-July. The size at first maturity was approximately equals 14-15 cm. Ageing was carried out using primary growth rings in the otoliths and length-frequency analysis of fish caught by shrimp trawlers. Von Bertalanffy's growth equation parameters were determined. Males and females grew in similar fashion. There are seasonal trends in the catch composition of the gill net fishery, showing high values during April to September and low during October to December.

    Description: Asian seabass, Lates calcarifer (Bloch) - a catadromous centropomid perch, is a good candidate species for brackishwater aquaculture in India. The length-weight relationship and the relative condition of L. calcarifer were assessed under culture condition. The length of the fish samples ranged from 25 to 240 mm and the relative condition (w sub(r)) of the fish for different length groups ranged from 99.54 to 104.39, indicating the good condition of the fish. The regression analysis of log-transformed length-weight data was carried out and the 'b' coefficient indicates the good condition of fish showing an isometric growth in the juvenile phase under culture condition.

    Description: Lepturacanthus savala (Cuvier, 1829) constitutes a minor fishery contributing 23.3% to the total ribbonfish catch in Maharashtra. Based on the length data obtained from shrimp trawlers and the traditionally operated bag nets, age and growth of the species have been investigated from Mumbai waters. Growth was studied by various computer-based methods incorporated in FiSAT Programme. The growth parameters L∞ and K (on annual basis) by Gulland-Holt plot were 683.3 mm and 0.87, respectively. As the seasonal temperature variations in coastal waters of Mumbai are not pronounced, the seasonally oscillating growth patterns by ELEFAN and Appledoorn's method were not considered. Following the von Bertalanffy growth model, the fish attains 399.8, 567.2 and 637.4 mm at the end of 1, 2 and 3 years, respectively, and the lifespan of the fish is about 3.3 years.

    Description: Macrobrachium rosenbergii post-larvae with an average weight of 6.26 ± 0.23 mg and an average length of 10.67 ± 0.13 mm were fed with one of the five experimental diets having graded levels of lipid (5.0, 7.5, 10.0, 12.5 and 15.0%) to satiation two times a day to study their effect on growth, survival and feed utilisation. The highest weight gain was observed in post-larvae fed 7.5% lipid, although there was no significant difference (p〉0.05) between groups fed 7.5 and 10.0% lipid. Similar effect was observed in the specific growth rate and protein efficiency ratio of post-larvae fed the diet with 7.5 and 10.0% lipid. The lowest feed conversion ratio was obtained in postlarvae fed the diet with 7.5% lipid. The survival rates of post-larvae fed on various levels of dietary lipid differed significantly (p〈0.05) after 15 days of rearing period. Significantly lower survival was observed in the diet with 15.0% lipid level. Dietary lipid did not significantly affect prawn carcass protein, lipid and ash contents. Based on the data analysis (ANOVA – one way analysis), the dietary lipid requirement for 15 days of nursery rearing of Macrobrachium rosenbergii post-larvae was estimated to be 7.5 to 10.0% under experimental conditions in this study.

    Description: A 30-day experiment was conducted to determine the effects of varying feeding rates on the growth of fry of silver dollar, Metynnis schreitmulleri (Ahl). Silver dollar fry with an average initial body weight of 1.100 ± 0.029 g were collected from a local fish breeder and fed a diet (35% protein and 6% fat) at the rate of 3, 6 and 9% of body weight per day in two equal meals. Per cent weight gain increased from 54.54 to 118.18 with increased feeding rates, which were significantly different (p〈0.05) from each other. The highest specific growth rate was obtained in the fry fed at 9% body weight per day. In another study for 30 days, the effects of feeding frequency on growth, feed conversion and protein efficiency of silver dollar fry were evaluated. Groups of silver dollar fry with an initial individual weight of 0.700 ± 0.019 g were offered feed continuously for 24 hours during the day or night at different time intervals with varying meal sizes. The night time feeding with two meals gave the lowest weight and length gains (0.985 g and 0.30 cm). The growth rates of fish fed during day with three equal-sized meals are significantly (p〈0.05) higher (4.66%) than the other treatments.

    Description: Effects of different levels of salinity on survival, growth and gonadal development of Genetically Improved Farmed Tilapia (GIFT) were studied under laboratory conditions in glass aquarium, for a period of ten weeks. The initial individual size of the GIFT was 20.23±4.45 and the salinity levels tested were 0, 5, 10, 15 and 20 ppt. The highest survival of 87.5% was found in 0 ppt and the lowest 60.5% in 20 ppt. Though the survival decreased progressively with increased salinity, there were no significant differences (P〉0.05) among 0, 5, and 10 ppt. Similar to what has been observed in survival, the specific growth rate (SGR %/day) also decreased as of 1.30, 1.24, 1.08, 0.90 and 0.71, respectively, with the increased salinity of 0, 5, 10, 15 and 20 ppt. The gonadal development was highest in 0 ppt with a GSI value of 3.75 and lowest of 2.01 in 20 ppt. In the second experiment, gonadal development and seed production performance of GIFT in brackishwater condition were investigated for a period of three months. Each of the three fine meshed hapas of 20 square meters made from nylon net was placed in a freshwater (0 ppt) and in a brackish water (10-15 ppt) pond of the Brackishwater Station (BS). GIFT of 65 g average weight from a single cohort were stocked into three hapas at a rate of 2 per m. The male vs female ratio was 1:3. The development of gonad was faster with the higher gonadosomatic index (GSI %) of 3.85 % in freshwater condition than that of 2.73 % in brackish water. Within three months of the study period, a total of 70,510 and 44,250 GIFT fry were produced respectively, in freshwater and brackishwater conditions. Finally under third experiment, a participatory on-farm trial was carried out to evaluate the production performance of GIFT in monoculture and in polyculture with silver barb in coastal freshwater pond conditions. Nine ponds were selected for three treatment combinations of GIFT monoculture (T1), GIFT and silver barb polyculture (T2), and silver barb monoculture (T3). The ponds have been stocked in April, 05 at a density of 25,000 fry per ha. Fishes were fed with rice bran at the rate of 6% bw per day. In one month culture period, GIFT attained an average weight of 16.27 g in monoculture and 17.23 g in polyculture, against an average stocking weight of 0.37 g. Silver barb reached an average weight of 16.62 g in polyculture with GIFT and 10.01 g in monoculture, against an average stocking weight of 3.79 g.

    Details
    Publication Date: 2021-05-19
    Description: Probiotics, as a live microbial dietary supplement, play an important role in the growth and activity of the host digestive enzymes by balancing the gut microbial population.The present study was conducted with 4 treatments and 3 replications including diets containing 1×106, 3×106 and 5 ×106 (cell/ g feed) and control (basal diet without yeast) to evaluate the effect of different levels of dietary supplementation of Saccharomyces cerevisiae on growth performance, body biochemical composition and digestive enzymes activities of grey mullet, Mugil cephalus. The fish (5.56±0.65 g) were randomly allocated into 12 fiberglass tanks at a density of 20 individuals per tank with three replicates for each treatment and fed with the experimental diets for 60 days. The results indicated that the diet at 5×106 yeast cells/ g( significantly improved weight gain (240.36±13.57%), final weight (919.28±1.55), protein efficiency (10.01± 0.56%) and survival (94.40±13.57%) compared to the control and treatment 2 (p〈0.05). Also, the highest activity of amylase (199.50±17.70 U/mg protein) and protease (362.50±13.52 U/mg protein) were observed in 5×106 yeast cells/ g diet (P〈0.05). This study shows that the use of S. cerevisiae 3×106 and 5 ×106 yeast cell/ g feed can have positive effects on growth performance, feed utilization, body chemical composition and digestive enzymes activities of M. cephalus.

    Publication Date: 2021-05-19
    Description: The aim of this study was to evaluate the efficacy of white spot virus vaccine produced by gamma iradiation in the face of Litopenaeus vannamei in comparison with Gracilaria corticata and Saccharomyces cerevisiae Seven hundred and twenty healthy shrimp SPF L. vannamei subadult with average weight of 10±1.02 g were collected and divided into 8 groups. The first group (T1) was fed with commercial pellet as control. The second group (T2) was fed with S. cerevisiae added to shrimp feed (1 g/Kg), the third group (T3) G. corticata so that algae Gracilaria were dried and added to shrimp feed at the rate of 1500 mg per kg and finally, the fourth group (T4) was vaccination group which the shrimp were exposed to the vaccine and injected intramuscularly gamma irradiant WSSV (1µl/gbw) for 10 days. The shrimps of all groups were then injected with WSSV and maintained for 25 days. Results indicated that the survival rates for groups T4, T3 T2 and T1 were 57.05±3.52%, 22.5±0.5%, 15±1.05% and 00.0±0%, respectively. Ultimately, at the end of the study the shrimp group T4 showed higher hematological data: THC, TPP, SOD, POD and PO. The study concluded that gamma irradiant WSSV is effective immunostimulants in shrimp L. vannamei and the immunity has better performances than those of the G. corticata and S. cerevisiae.

    Description: Trawls, seines, and trammel nets were used to sample the Galveston Bay crab populations. The data collected were used in determining the seasonal abundance of the crabs as compared to previous years' sampling. Blue crab populations in 1962 appeared to be larger than in 1961. The female population lagged behind the male in abundance in all months in 1962 except April, October, and December. The movement of adult crabs appeared to be governed by their search for food, reproductive cycle, and seasonal temperatures. Juveniles remained in the bay all seasons, moving toward the primary bay as they grew. Growth rate of the juvenile crabs was 0.4mm per day.

    Description: In 1965 shrimp and associated bottom organisms were sampled for type, abundance, size groups, and seasonal availability with a 23-25 foot flat otter trawl in the Gulf of Mexico off Port Aransas, Port Mansfield, Port Isabel, and briefly off Galveston, Texas. In regular weekly samples, commercial shrimp of four species, non-commercial shrimp of 7 species, two species of squid, and various associated animals were caught in 100 trawl samples. Brown shrimp, Penaeus aztecus, were the most abundant of the commercial species, followed by white shrimp, Penaeus setiferus, and pink shrimp, Penaeus duorarum. Trachypeneus similis and Squilla empusa were the most abundant non-commercial species. This survey indicates the seasonality of Gulf shrimp populations and the cyclic growth and migration patterns in inshore waters. Periods of abundance are noted for all shrimp. Growth cycle information is given for brown, white, and pink shrimp. Any variation of catch between areas sampled is noted, and data on non-commercial species area included for more comprehensive understanding of the ecology of the inshore Gulf of Mexico.

    Description: Four feeds having different protein levels were separately tested on Tor khudree fry having an average length of 23.5 mm and weight 55 mg. The best average growth of 15.66 mg and 0.456 mm/day was obtained with Feed IV which comprised rice bran, ground nut oil cake, Acetes, wheat flour and mineral mix at the ratio of 1:1:1:0.7143:0.01428. These constitute 35.29% of proteins. The Feed II which comprised R.B + G.O.C. + prawn shell + wheat flour and mineral mix at a ratio of 1:1:1:0.7143:0.01428 contained 32.61% crude proteins. It provided a growth rate of 14.83 mg and 0.440 mm per day. The conversion rates were 38.258 and 37.776 for feeds IV and II respectively. Since Feed II is cheaper than Feed IV and provides almost equal growth rate, it can be used in the nurseries for intensive rearing of T. khudree fry.

    Description: In spring many brown shrimp, Penaeus aztecus, nursery grounds in Texas were adversely affected when fresh water inflow lowered salinities, Brown shrimp abundance trends were relatively high in Aransas, and Corpus Christi Bays, but low in other bays. White shrimp, P. setiferus, were scarce in summer. In fall they were abundant in Sabine Lake and Galveston Bay. Commercial brown shrimp production was high; white shrimp production was low. Total production (43.1 million pounds, headless) decreased 4.6 million pounds from 1965. Factors which influence brown shrimp survival, growth, and average size are discussed.

    Description: Biochemical composition of the muscle of juveniles belonging to 18 different species of freshwater fishes showed that the protein percentage in juveniles was higher than the adults. The fat, on the other hand, was much lower. This suggests that the body fat increases with the onset of maturity. No clear inverse relationship was found between fat and protein in juveniles. Moisture percentage was very high in juveniles. This was probably because of low fat content. In most species the sum of fat and water contents (F + W) was found to be constant. The percentages of ash, calcium and phosphorus were higher in juveniles than those of adults. Dry matter percentage varied inversely with the moisture and in most species carbohydrate was generally low. In juveniles although the calorific value of protein-fraction was high the total calorific value was lower than the adults.

    Description: Some biological characteristics of broodstock and juvenile kutum, Rutilus kutum. were investigated using data collected from the estuaries of Tajen and Shirood Rivers (TR and SR) (south Caspian Sea basin) as well as from the Caspian Sea in 2012. The results showed higher condition factors (CF) in the male broodstocks than those estimated in the female broodstock of both TR and SR. The female juveniles displayed a greater level of CF. The Von Bertalanffy's growth equations were calculated as: Lt = 40.67(1 – e−2.27(t−18.84)) and Lt = 50.11(1 – e−0.48(t+1.814)) for the broodstocks of SR and TR, respectively, and for the juveniles as: [Lt = 48.36 (1 – e−0.537 (t+ 0.913]. The males of SR presented a negative allometric growth pattern.The females and males of both SR and TR presented similar isometric growth patterns. Both male and female juveniles from TR exhibited a positive allometric growth pattern. The calculated equations for total length and weight were as: W = 3E−06 L3.2069 and W = 5E−07 L3.4745 for the male broodstock of SR and TR, respectively, and as: W = 5E−07 L3.4745 for the juveniles. The measured parameters may reflect the role of fish habitat characteristics such as food availability, population density, and age classes depending on sex and season.

    Description: The aim of this study was to provide necessary information on the age, growth and sex ratio of one of commercially important cyprinid species, Alburnus chalcoides in the southern Caspian Sea (North of Iran) from 2010 through 2011. 53 specimens of both sexes (males and females) were collected monthly. The samples were transported to the laboratory for further biological measurements and otolith extraction. The maximum and minimum age of A. chalcoides was 4+(FL=26.0 cm) and 1+ (FL= 18.1 cm), respectively. The mean fork length of A. chalcoides was 20.21±0.287 cm; and the sex ratio was 1.00: 2.12. The calculated length-weight relationships for all individuals were as W=0.141TL2.199 (R2= 0.648). Different regressions were prepared between age and morphological measurements of fish and otolith, of which the highest correlation was between age and body length as a linear regression of TL=1.959Age+16.32 (r= 0.66). There was no significant correlation between morphometric measurements of otolith and fish morphological parameters (p〉 0.05), and an allometric growth was found with a slope of b=1.926 for the study area.

    Description: This study was investigated the effects of dietary estradiol-17β (E2) on growth, body composition and blood indices in Acipenser stellatus. Fish (40.9 ± 1.1 g average initial weight; n = 60 per group) were fed with three different diets containing 0 (control), 25 and 50 mg kg-1 dietary estradiol contents to apparent satiation for seven months. The results suggested that growth rate were decreased as the E2 level was increased. No significant difference was observed in condition factor among dietary treatments. The highest survival rate was observed in fish fed control diet, but was not significantly different among the treatments (P〉0.05). Body composition did not show significant changes among dietary treatments. Number of white blood cells and red blood cells, hemoglobin and hematocrit values were significantly decreased as the E2 levels were raised (P〈0.05). Plasma biochemical parameters including glucose, total protein, cholesterol, triglyceride, calcium, and phosphorus levels were dose dependent with the lowest levels in control with the highest levels in fish treated with 50 mg E2. The results of the present study revealed growth suppression of dietary E2 and changes of blood indices with providing some basic information on the effect of estrogen hormone on physiology of sturgeon.

    Description: The probiotic effects of inactive yeast, Saccharomyces cerevisiae var. ellipsoideus was studied on growth performance, survival and intestinal microbiota of beluga juveniles (Huso huso). The study was done in complete randomize design that included feeding of beluga juveniles with diets supplemented with 0 (control), 1, 2 and 5% yeast (4 treatments with 3 replicates). Beluga juveniles (11.40±0.56g) were randomly allocated in 12 oval tanks at a density of 35 fish per tank and triplicate group were fed with experimental diets. At the end of the trial, growth factors (final weight, weight gain, SGR, CF) as well as feed conversion ratio (FCR), body composition (protein, lipid, ash, moisture) and intestinal microbiota (total viable bacteria and Lactobacillus spp. levels) were determined. Our results confirmed that juveniles fed on diet supplemented with 5% S. cerevisiae var. ellipsoideus had significantly higher final weight, weight gain, specific growth rate (SGR) and lower food conversion ratio compared to control and 1% treatment (P〈0.05). However, there were no significant differences between SGR of 5 and 2% yeast treatments (P〉0.05). The study of body composition showed no significant difference between treatments (P〉0.05). Total viable bacteria and Lactobacillus spp. count were significantly higher in 5% treatment compared to control (P〈0.05). However, there was no significant difference between Lactobacillus spp. levels in 5 and 2% treatments (P〉0.05).

    Description: Effects of Goldstrip sardine (Sardinella gibossa) and poultry by-product protein hydrolysate on amino acid composition, growth and alevines survival of rainbow trout (Oncorhynchus mykiss) were investigated. Two hydrolyzed protein sources were incorporated into six diets for start-feeding rainbow trout (Oncorhynchus mykiss) alevines, in 3 different replacing levels (10%, 25% and 50%) of fish meal. Goldstrip sardine protein hydrolysate (SPH) and poultry by-product protein hydrolysate (PPH) were used, respectively. To compare the results, we used the same diet without protein hydrolysate. The diet with 25% SPH and 10% PPH offered the best results in terms of growth, survival, protein efficiency ratio, protein productive value and condition factor. Alevines fed with 25% SPH and 10% PPH showed more balanced amino acid composition in their body. By enhancing the protein hydrolysate in the diet, free amino acid composition in the diet and fish body was enhanced. The protein hydrolysate enhancement showed negative correlation with growth factors. Also, non essential amino acid composition of the body composition showed positive correlation with the lipid/protein percentage of the alevines. We conclude that an optimum level of protein hydrolysate can improve growth and performance of the rainbow trout alevines. However, excess protein hydrolysate can cause imbalanced amino acid composition in fish body and reduces the growth and survival factors. Based on this study, the optimum replacement of fish meal by SPH and PPH in rainbow trout alevines’s diet is 25% and 10%, respectively.

    Description: A 10-week feeding experiment was conducted to investigate the effect of dietary n-3 highly unsaturated fatty acids (n-3 HUFA) and vitamin E interaction on growth, apparent digestibility, apparent retention and utilization of lipid in Caspian salmon fry. Six experimental diets combining three different dietary levels of n-3 HUFAs (L: low: 1+0.5, DHA+EPA, M: medium 2+1, DHA+EPA, H: high 4+2 DHA +EPA g/100g diet) with two different levels of vitamin E (L: low 300 and H: high 1000 mg/kg diet): LL, LH, ML, MH, HL and HH (HUFA/vitamin E) were investigated. Fry with initial mean (±SD) body weight of 600 ± 25 (mg) were randomly distributed in tanks and fed to apparent satiation. Increase in dietary HUFA and vitamin E markedly improved larval growth. The results showed that the survival of Caspian salmon fry was not affected by dietary omega-3 HUFA and vitamin E. C20:5n-3 and C22:6n-3 fatty acids content of polar and neutral lipids positively correlated with their concentration on diets. Apparent digestibility and apparent retention of total lipid was significantly affected by dietary HUFA. The results showed that n-3 highly unsaturated fatty acids and vitamin E had positive effects on growth performance, lipid metabolism and apparent digestibility of Caspian salmon fry.

    Description: Fermented sausage is a favorite kind of meat-product that has allocated great proportions of meat consumption in the world. For the first time in Iran in this study the production of Fermented sausage from minced meat of common carp was assessed by means of lactic acid bacteria at different incubating temperatures as 15, 25, and 35˚C. To prepare the fish sausage, common carp mince was grounded and mixed with NaCl (3%), glucose (3%) and lactic acid bacteria at 5 log CFU/g and afterward were incubated for 48 h. During the incubation of fish sausage, microbiological tests, moisture and protein content, and TVB-N were measured. According to the results, the higher temperature of 35˚C stimulated the rapid growth of lactic acid bacteria, resulting in a rapid decline in pH, and consequently suppressed the growth of pseudomonas, Micrococcaceae and Enterobacteriacea.

    Description: Chamomile is a rich source of phytoestrogens; these compounds have antioxidant, anticancer. In this study, the effects of chamomile on growing oocytes in immature female gourami fish were examined. Thus 60 immature female gourami fish with an average weight of 2-3 g of 6-treated group were analyzed. Treatments in a completely randomized experimental design with a dose of chamomile (10-20-30-50 mg/kg fish) along with control (no injection) and ethanol control (solvent injection) and with three replicates were tested. The fish adaptation to the environment lasted 3 days. The extract injections were done for 20 days, in 10 periods, every other day. In order to histological study, three days after end of the experiment, the ovarian tissue was removed and weighed, tissue processing and staining steps done with hematoxylin- eosin. At last the histological structure of the ovaries and the average percentage of treated fish gonadal indices were compared with the control group. According to our results of gonadal index, there was no significant difference between the control groups with receiving Ethanol (p〉0.05). Histological results showed that increasing the dose of chamomile extract accelerate oocyte maturation in three spot gourami. This is the fourth treatment (dose, mg / kg 50) to show its obvious. The difference between oocyte diameter was observed with increasing doses of Chamomile and in comparison with the control group, the difference was significant (p 〈0.05). Histological results showed that increasing the dose of Chamomile accelerate oocyte maturation in three spot gourami.

After 2 weeks adaptation, 240 fish with 19.5 ± 0.2 g average weight were randomly distributed in to 12 fiberglass tanks with four treatments and three replicates (20 fish per tank). Based on body weight, cortisol (mixed with oil) was injected to treatments with different dosages at 0 (C0), 1 (C1) and 10 (C10) µg/g. At the end of 21 days, fish were weighed and growth parameters showed significant reduction in C10. No significant change was observed in hepatosomatic index among different treatments. Food intake were recorded daily during the experiment and showed significant reduction in days 1 to 8, 16 and 19 in C10 compared to control group . Blood was taken to determine plasma cortisol at the start, day 3, day 7 and day 21 of the experiment. Cortisol concentrations showed significant reduction in C10 compared to C0 group three days after the initiation of the experiment. The results showed that increasing of cortisol in a short time after injection, affected by changes of blood plasma cortisol and reduction of food intake could negatively have an effect on growth.

    Description: This study was conducted to investigate the effects of different levels of sangrovit (0, 0.05, 0.1 and 0.15 %) on growth, some of blood biochemical parameters, survival and salinity tolerance capacity in Cyprinus carpio (2.62±0.117 gr). After 45 days of feeding, results showed that growth performance including of weight gain and % specific growth rate improved which fish fed whit sangrovit compared with to control group, but there was no significant differences in growth parameters which fish fed with herbal supplement compared to control group (P〉0.05). There were significant differences in biochemical parameters in fish fed with sangrovit compared to the control group (P〈0.05). The lowest level of cholesterol was observed in 0.05 % group and the highest level of total protein was observed in 0.15 % group. The highest levels of glucose observed in control treatment. In order to determine the effect of the herbal supplement on resistance to salinity stress, salinity stress was carried out after 45 days of feeding. Blood samples were obtained at 24, 72, 120 and 168 hours after stress. Hematocrit had significant difference in each groups (P〈0.05). On the third day after stress, hematocrit levels were decreased in all treatments. Survival and tolerance to salinity stress challenge remained unaffected by dietary supplementation of sangrovit. The results of this study showed that addition of sangrovit to fish diet can improve growth performance and blood biochemical parameters of common carp fingerlings.

    Description: Around ten thousands fries of Striped grey mullet (Mugil cephalus) with average weight and length of 280 mg and 28.3 mm respectively, imported in March 2008 from Egypt. The wild fries collected from surrounding natural waters of Alexandria. They stocked in four earthen ponds (each with 2500 m2 ) located at the Gomishan shrimp educational centre at late march in 2008. At the first year of culture the densities were 5000 and 10000 individuals per hectare and each treatment with two replicates. At second year, densities changed with 2000 and 2500 individuals per hectares and each of the treatments divided fishes with average primary weights of 80 and 115 grams. They fed twice a day at 8 AM and 2 PM and the amount was 5-7 percents of the fish existent biomass in each ponds. After seven months culture period, the average weight and length of fish in treatment 5000 ind./hec. were 113.7 gr and 21.1 cm respectively and in treatment 10000 ind./hec. the average weight and length were 86.6 gr and 19.6 cm respectively. At first year the average survival rate in different treatments was 77 percent. The average FCR in treatments 5000 and 10000 ind./hec. were 3.4 and 3.9 respectively. At second years after six months culture the average weights in pond no. 9 (with primary weight 115 gr and density 2000 ind./hec) , pond no. 10 (with primary weight 80 gr and density 2000 ind./hec) , pond no. 11 (with primary weight 115 gr and density 2500 ind./hec) and pond no. 12 (with primary weight 80 gr and density 2500 ind./hec) calculated as 476.6 ,338.1, 366.5 and 440 gr respectively. The average survival rate and FCR were 93 % and 3.1 respectively.

    Description: This experiment was carried out to evaluate the effect of earthworm (Eisenia fetida) in diet for rainbow trout in a complete randomized design with 5 treatments in triplicates using 15 cages in a pound for 8 weeks. Ten fish with average weight 120 g was stocked in each replication. The earthworm (as fed) at the levels of 0, 25, 50, 75 and 100% was replaced with fish meal in rainbow trout diet. Results showed that feed intake decreased significantly (P 〈 0.05) as earthworm increased. The diets contain 25% and 50% earthworm showed no significant differences compared to control for weight gain, specific growth rate and feed conversion ratio (P 〉 b0.05). The chemical composition analysis of fish meat showed that there were no significant effects between control and 25% and 50% earthworm in diet for dry matter, crude protein and ash, but fat content significantly decreased as earthworm increased (P 〈 0.05). This present study showed that the earthworm (Eisenia fetida) can be used in rainbow trout diet up to 50% instead of fish meal.

    Description: In this study, the effect of commercial food replacement with earthworm (Eisenia foetida) on growth, survival, the number of larvae and their resistance to larval salinity stress in Swordtail fish (Xiphophorus helleri) was investigated. A completely randomized design experiment comprising of four treatments: T1 (100% commercial food), T2 (25% Earth worm +75% Commercial food), T3 (50% Earth worm + 50% commercial food), T4 (75% Earth worm + 25% Commercial food) were performed in triplicate. Swordtail fish were fed with 3% of its weight, 3 times per day. After a 60-day experimental feeding period, growth factors and survival rate of fish fed with different diet treatments were not affected. However, the growth factors and survival rate were affected by sex and the weight gain, specific growth rate and survival rate of females was significantly higher than males. The highest number of born larvae was observed in T2 which was significantly more than control. (P〈0.05). In T4, larvae showed the lowest resistance to salinity stress test (P〈0.05). Results showed that number of born larvae significantly increased in 25% replacement than control, so the Swordtail fish could be fed with low levels (25%) of earthworm without any unfavorable effects on the growth and survival rate and their larval resistance to salinity stress test.

    Description: In this research, growth rate, blood parameters and proximate composition of rainbow trout (Oncorhynchus mykiss) cultured in brackish and freshwater were evaluated. Two treatments (brackish and freshwater) in 3 replications were investigated. Six 1.5 m³ fiberglass tanks were used for this experiment, containing 180 rainbow trout specimens with average weight of 47.2±0.1g. Feeding rate in treatments was about 3% of body weight based on water temperature and fish biomass. Total length and weight of fish were measured in 15 days intervals. After 135 days of culture period, some fish samples were transferred to the Lab. Blood were directly collected from the heart. Muscle composition was analyzed for proximate composition. The results showed that the body weight of samples in brackish water was increased significantly after 45 days of culture period. Blood factors including WBC, RBC, Hb, Hct, MCV, MCH, MCHC, lymphocyte, thrombocyte and concentration of K+ ions in fish cultured in brackish water showed a significant increase (P〈0.05). Muscle composition analysis showed a significant increasing (p〈0.05) in fat and dry matter in freshwater treatment, while moisture was significantly higher in brackish water (P〈0.01).

    Description: Phytoplankton growth and microzooplankton grazing were investigated at one station in the Homa Lagoon from February to January in 2006-2007. Our results showed significant seasonal variations in phytoplankton dynamics. Microzooplankton was mainly composed of dinoflagellates and tintinnid ciliates and nauplii. Microzooplankton grazing increased with increasing of temperature. Grazing rate was maximum levels in spring and summer. Microphytoplankton, which dominated the total algal biomass and production, were characterized by the proliferation of several chain-forming diatoms. Small heterotrophic flagellates and aloricate ciliates were the main controllers of phytoplankton. Phytoplankton represented a significant for micrograzers, which grazing represented 20–120% of diatom and cynabacteria algal production during 2006-2007. Microzooplankton has, however, a relatively high impact on microphytoplankton, as 〉 45% of microalgal production was consumed throughout the year. These results suggest that the low grazing was one of the factors contributing to the development of the spring bloom. All of seasonal bases, the phytoplankton production were grazed by microzooplankton in summer, autumn and winter–spring seasons have been changing between 20%-120%. The seasonal variation in the microzooplankton grazing pressure seems to result from the dominant size class of the phytoplankton community of this lagoon diatom and cynabacteria.

    Description: In this study, a feeding trial was conducted to examine the potential of replacing fish meal with brewers yeast in practical diet of goldfish (Carassius auratus). Five isoproteic (37% CP) and isocaloric (3350 kcal/kg) diets were formulated to contain graded levels of brewers yeast. Fish meal protein was replaced by 0%, 15%, 25%, 35%, and 45% of yeast. Each diet was randomly allocated to triplicate groups of 20 fish (initial average weight of 0.56 g fish^-1) in glass aquarium (65L). Fish were fed three times per day to apparent satiation for 84 days. At the end of the experiment, weight gain, specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER), condition factor (CF), survival rate (SR), hepatosomatic indices (HSI) and body composition of goldfish fry were determined. According to the results, weight gain, SGR, FCR and PER of fish fed the diet including yeast replaced 35% of the fish meal were better than those of fish fed the other diets. There were no significant differences in SR and HSI values among fish fed diets (p〉0.05). However, CF among fish fed the experimental diets was significantly different (p〉0.05). Whole body composition was similar among fish fed different diets. The optimal replacement level of fishmeal protein by brewers yeast was determined by second-order polynomial regression to be (y= 2, 2237- 0,0004x^2 + 0,0279x; R² = 0,9977) 34.875%, on the basis of SGR.

    Description: The genus Azolla forms a group of small-leafed, floating aquatic ferns native to the tropics, subtropics,and warm temperate regions of Africa, Asia, and America. For several decades, these ferns have been utilized for various purposes: e.g. as green manure, feed for animals, but also for the removal of different metals (e.g. Hg, Pb, Cr and Cd) through wastewater treatment or for elimination of nitrogenous compounds from surface water. Notwithstanding, these many advantages of Azolla, it has invaded many natural habitats, thus becoming an obnoxious weed. Azolla can grow quickly with a doubling time of only 2-5 days and form very dense mats in favourable habitats, causing many difficulties for boat transport, water animals and native plant species and becoming a source of eutrophication. The present paper gives an overview of some important ecological factors affecting Azolla’s growth over the past few decades. Moreover, for the most ecological variables discussed in this study, the authors refer to their recent publications for the habitat requirements of Azolla in Anzali wetland. Water availability is the key factor for its growth. Growth is further promoted by optimal light intensity (15-18 Klux), temperature (18°- 28°C) and relative humidity (55-83%). Wind and turbulent water can fragment and kill Azolla. The importance of both macro (e.g. phosphorus, nitrogen, potassium, calcium and magnesium) and micronutrients (e.g. molybdenum, cobalt and etc.) has also been confirmed from literature. Various types of insects (e.g. caterpillars), bacteria, fungi and viruses can affect Azolla growth. As a conclusion,understanding the habitat requirements of Azolla is very helpful for managing this aquatic fern, also for decision making in the context of wetland restoration and conservation management.

    Description: Saprolegnia is one of the most important agents decreasing the eggs survival rate in sturgeon hatcheries.There are some chemical substances for controlling the fungal infection of eggs. In this study, an attempt was made to introduce a germ negative bacterium, Pseudomonas aeroginosa (PTCC1430)(Persian Type Culture Collection) as a biocontrolling agent of water mold. Saprolegnia was isolated from the eggs of some infected Persian sturgeon, Acipenser persicus in a sturgeon hatchery and then was purified. P.aeroginosa was cultured in Potato dextrose Agar (PDB) media and then was prepared in 5 concentrations (103,104,105,106and107cfu.ml-1) while challenging with fungi in petri dishes under laboratory conditions.The results showed that by increasing the concentration of the bacteria in plates, hyphal growth of the fungi was reduced. The highest concentration of P. aeroginosa concentration (107) roughly stopped the -fungi growth and the Minimum Inhibitory Concentration (MIC) was 104cfu.m-l. Results in this study implied the potential of P. aeroginosa (PTCC1430) as a biological agent in controlling saprolegniosis.

    Description: The growth of organisms on seven different artificial reef structures was surveyed from 2004-2006 in Hormuzgan offshore waters (Bandar Lengeh area). The organisms consisted of 12 groups the main of which included Barnacle (Megabalanus tintinnabulum), Sponges with five families and Tunicates. The highest density was observed in 2005, amounting to some 409.224g wet weight on each structure. However, a decrease was observed afterwards in the total mass of aquatics living on the structures. Some organisms such as crabs, polychaets, bivalves and fish larvae showed an increasing in size in the first year. Bivalves showed a decreasing trend in density but otherwise an increasing trend in size over time. Artificial shape of the reefs was not effective on the total density of the organisms living on the structures. Total density of live organisms on different parts of the artificial reefs (surface, middle and bottom) was not statistically significant (P〉0.05). Numbers of crabs on mixed artificial reefs were higher than the other artificial reefs. This was also the same for barnacles.

    Description: Rutilus firisii kutum is one of the important fish in Caspian Sea that has significant economical role to the region. The overall objective of the project is to compare the growth and survival of Rutilus frisii Kutum larvae under conventional conditions and conditions under use of organic fertilizer by anaerobic fermentation or slurry. This study was conducted in nine 1.7 hec pounds with 3 treatments with stocking densities of 1.7 million fish larva at Dr Yousefpoor Center at Siakal Village, 32km far from city of Rasht in North of Iran. The first treatment considered as control using concentrated food and grinded kilka fish. In the second treatment, the pound was supplied only by slurry for 13 days followed by concentrated fish food. The third treatment started with slurry for 13 days followed by slurry and concentrated food together. The physical and chemical parameters of water, plankton, biometry of fish, growth indices were monitored weekly. The result indicated that production was 1.7 to 2 times higher in slurry than traditional treatment also the survival rate was 1.7 times higher in slurry treatment. Slurry with several active substances is more effective and can promote the growth of zooplanktons that is the food for larval stage of Rutilus frisi kutum. Nutritional contents of phosphorous, nitrogen, calcium, magnesium, potassium, protein and lipid after anaerobic fermentation were higher in slurry treatment than control. The blue-green algae density in slurry pounds was less than control.

    Description: The effects of dietary vitamin C and Lactobacillus rhamnosus on immunity and growth performance were investigated in Oncorhynchus mykiss. For this purpose, 480 rainbow trout (68±5g) were obtained from a local farm and acclimated to laboratory conditions for 10 days and then divided into four groups in three replicates. During 30 days, juvenile rainbow trout were fed diets supplemented with vitamin C (1g/kg) and L. rhamnosus (at 5 × 107 CFU/g) or a control diet. Biometry was done at day -30 and blood samples were taken by caudal vein after fish anesthesia with clove powder at day 0, 15, 30 and 45. Serum lysozyme activity, alternative complement activity and total plasma immunoglobulin level were assayed as innate immune response of rainbow trout. Results showed fish fed with vitamin c and L. rhamnosus (group 3) statistically could improve fish growth performance. Also lysozyme activity and alternative complement activity of serum significantly were higher in group three than other groups, but total plasma level of immunoglobulin only was higher than all groups at day 30. In conclusion dietary administration of vitamin C and L. rhamnosus in rainbow trout diet could enhance the growth and innate immune response, but these properties need further studies on the field applications.

    Description: In this study, the effect of ethanolic extracts of Sargassum angustifolium on growth and survival of shrimp Litopenaeus vannamei juvenile was investigated under challenge with shrimp pathogen bacteria Vibrio harveyi. Powder form of the extract was bioencapsulated in Artemia and fed to L. vannamei juvenile reared as 5 groups inclouding C- (unenriched Artemia, without bacteria), C+ (unenriched Artemia, with bacteria), T1 (enriched Artemia with 200 mg l-1 SA extract, with bacteria), T2 (enriched Artemia with 400 mg l-1 SA extract, with bacteria), T3 (enriched Artemia with 600 mg l-1 SA extract, with bacteria). One week after culture all groups except C- were inoculated with V. harveyi at the rate of 1.5 × 108 CFU ml-1 for 15 minutes then after every water exchange 10 ml of V. harveyi at the rate of 1.5 × 107 CFU ml-1 was added to aquaria. Shrimps at group C- showed maximum survival (86.6%), specific growth rate (SGR, 11.33%) and less bacterial load (0.5 ± 0.03× 102 CFU g-1 tissue). While (C2) exhibited lowest survival (33.3%), SGR (9.90%) and more bacterial load (3.4 ± 0.05× 105 CFU g-1 tissue) and the difference was significant (p〈0.05). In treatment groups survival and SGR were significantly (p〈 0.05) more than C+ and less than C-, also bacterial load were less than C+ and more than C-. Among treatment groups T2 that fed with enriched artemia with 400 mg l-1 SA extract gave better results than the other treatments.

    Description: Effect of different dietary carbon sources on water quality, growth performance and survival of western white shrimp Litopenaeus vannamei post larvae was investigated in zero-water exchange system. Shrimp postlarvae with mean weight of 98.47±8.60 mg and mean length of 22.39± 1.70 mm were fed for 32 days in fiberglass containers with 130 liters volume of water and density of 1 individual per liter in five treatments including one control with water exchange and four biofloc treatments with adding different carbon sources including molasses, starch, wheat flour and mixture of them at equal weight ratios with 15% to 9% of body weight. In the values of water quality parameters including temperature, salinity, dissolved oxygen and pH, no significant differences were observed among the biofloc treatments (P〉0.05). Maximum pH (8.27 ± 0.09) and maximum dissolved oxygen (6.37 ± 0.56 mg/lit) was in water exchange treatment. Maximum and minimum level of ammonia was 0.43± 0.34 and 0.09± 0.07 mg/lit in water exchange treatment without floc and biofloc treatment with adding starch of carbon sources, respectively and showed significant difference between treatments (P 〈0.05). The highest increase in body weight (1640.43± 231.28 mg), growth rate (51.26± 7.23 mg per day), specific growth rate (8.97± 0.42 %/day) and biomass (190.29± 26.83mg) was observed in biofloc treatment with adding molasses and the highest survival rate (90± 0.77%) was obtained in biofloc treatment with adding mixture of carbon sources. The highest feed conversion ratio (1.52±0.23) and the lowest feed efficiency (66.81±7.95) were obtained in water exchange treatment without floc, showing significant difference compared to the other treatments (P 〈0.05). The results showed that using biofloc technology with zero- water exchange system and adding carbonaceous organic matter could help to recycle waste and improve the water quality. Moreover, the presence of biofloc improved growth performance, feed utilization and production of western white shrimp in zero water exchange rearing system.

    Description: A feeding trial was conducted to examine the effects of dietary supplementation of lysine and methionine on growth, nutrient utilization and carcass compositions in beluga, Huso huso. Four experimental soy protein based diets D0 (without lysine or methionine supplementation), D1 (lysine supplementation alone), D2 (methionine supplementation alone) and D3 (both lysine and methionine supplementation) were fed to triplicate groups. 240 fish with an average weight of 144.6 ± 4.64 g were fed the experimental diets for 12wk. L-Lysine and DL-methionine were added to the diets containing 344 g kg-1 soybean meals at 22.02 and 12.94 g kg-1 of dry diet respectively. Significant higher weight gain, specific growth rate, protein efficiency ratio, condition factor, feed efficiency ratio, whole muscle protein and protein apparent digestibility were observed in fish fed soya protein-based diet supplemented with both lysine and methionine than that of fish of other dietary groups. There were no significant differences among fish fed diet supplemented with either methionine or lysine. Growth performances, feed utilization, carcass composition and apparent digestibility coefficients of protein, lipid and dry matter of fish fed control diet was significantly lower than those of fish fed diet supplemented both lysine and methionine and supplemented with either methionine or lysine. It can be concluded that beluga, fingerlings effectively utilize the supplemental amino acids (L-Lysine at 22.02 g kg-1 dry diet and DL-methionine at 12.94 g kg-1 dry diet) in the diets containing 344 g kg-1 soybean meals for better carcass proximate compositions, growth performance and feed efficiency and utilization.

    Description: Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the growth and survival of larval Persian sturgeon (Acipenser persicus). Four different Artemia enrichments ICES30/4 (with 20.90mg/g DW DHA and 6.29mg/g DW EPA), Sturgeon Ovary Oil (SOO) (with 2.76mg/g DW DHA and 7.55mg/g DW EPA), Cod Liver Oil (CLO) (with 7.64mg/g DW DHA and 11.39mg/g DW EPA) and Linseed Oil (LO) (with 0.00mg/g DW DHA and 0.03mg/g DW EPA) in seventy five aquaria (each 45 liter, with three replicates per treatment) were used. The resultant Artemia contained a different concentration of DHA (0.00-5.99mg/g DW) and EPA (0.69-4.97mg/g DW). Larvae were fed with Artemia from 3 to 20 days after active feeding at 250 prey 1^-1. Results showed that there were significant differences between treatments regarding to the total length and wet weight but no significant differences were found in dry weight between the larvae reared on different treatments. However, larvae reared on LO were significantly higher (in weight) than larvae reared on ICES30/4 and SOO. Larval survival on the SOO enriched Artemia (93.3±1.6) at 20th day was significantly higher than other treatments. Our results showed a positive effect of Artemia DHA proportions on growth and survival of the Persian sturgeon, and demonstrated that larvae of this species require a high ratio of dietary DHA to EPA.

    Description: The recent development of a short term, but very intense fishery for Pacific hagfish (Eptatretus stoutii) on the Pacific Coast of North America prompted concern over the absence of management and conservation guidelines for this species. However, very little is known of the biology of hagfish, particularly with regard to information applicable to fishery resource management. Growth and population age-size structure data are among critical categories of information that are non-existent to date. This project obtained primary growth information from field and laboratory studies as well as comprehensive population size composition data.

    Description: Recently, due to the high costs and a decrease in producing of Lansy PZ, various researches have been conducted to the baker's yeast (Saccharomyces cerevisiae) as a substitute for Lansy PZ in Artemia culture technologies. In this study, the effects of six feeding regimes: Lansy PZ (as control), enriched yeast with HUFA, enriched yeast with HUFA and without mannoproteins in wall cells, yeast without mannoproteins in wall cells, industrial yeast 100 %, and industrial yeast 50 % replaced with alga were respectively examined on the fatty acid composition of two Artemia species (Artemia urmiana and A. franciscana) at a salinity of 80 ppt and a density of 500 nauplii per liter in culture conditions. Results showed that the enrichment of baker’s yeast with HUFA had increasing trend on the EPA and DHA contents of baker yeast (19.11 and 34.51%, respectively). The yeast type had significant effect on the fatty acid composition of the two species of Artemia. The highest content of HUFA obtained when Artemia fed the Lansy PZ. Our results recommended that the Artemia fed with HUFA enriched yeast and enriched yeast with HUFA without mannoproteins in wall cells induced higher contents of essential fatty acid (especially DHA) compared to other treatments. On the basis of the present investigation, the enrichment of Artemia with yeast enriched HUFA can be substitute to Artemia fed with Lanzy PZ.

    Description: The age and growth of the Persian Sturgeon, Acipenser persicus, obtained from the Iranian coastal waters of the Caspian Sea, were studied through analysis of the pectoral fin ray section from 180 specimens, ranging in fork length (FL) from 66 to 203 cm. The specimens were obtained from commercial fisheries between October 2008 and June 2010. Interpretation of growth bands in the pectoral fin ray sections was carried out objectively using the direct reading of thin sections and image analysis. The maximum age recorded in this study for the spacimens of Persian Sturgeon was 39 years. The von Bertalanffy growth parameters estimated for females were greater than for males. The estimates of asymptotic length (L∞) and growth coefficient (K) of females were 173.07 cm and 0.1 year -1, respectively and for males 164.33 cm L∞ and 0.08 year -1 K respectively,. Total mortality coefficient (Z) for females and males was estimated to be 0.45 and 0.76 year -1, respectively. This study revealed differences in life history parameters of the Persian Sturgeon compared with those of previous studies, which may be associated with the current increased fishing pressure and degradation of environmental conditions.

    Description: An experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, Cyprinus carpio. Four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % Biogen probiotic were used to feed fish. Seventy-two juvenile common carp (65 ± 3.5g) were randomly distributed between 12 fiberglass tanks of 500 L capacity. During 60 days of feeding trial, the fish receiving probiotic feeds showed significantly higher growth performance in terms of weight gain (WG), specific growth rate (SGR), protein efficiency ratio (PER), food conversion ratio (FCR) and survival rate (SR) in comparison with those fed the control diet (P〈0.05). The best results in food efficiency and growth performance were observed in fish fed diets containing 0.3% of Biogen probiotic that were significantly different with that in other treatments (P 〈 0.05 ). Growth performance did not differ significantly (P〉0.05) in fish fed diets containing 0.1 and 0.2 percent of probiotic. Fish carcass composition in the diets receiving probiotic improved from initial values i.e. higher levels of protein and lipid with lower levels of moisture and ash content and showed significant difference (P〈 0.05) only with the basal control diet. There were no significant differences (P 〉 0.05) in body composition between the treatments which received probiotic.Feeding juvenile carp with diets containing Biogen probiotic improves growth performances and feeding efficiency in them; the optimum addition of probiotic is 0.3 g/100gof diet.

    Description: The effects of feeding frequency on growth performance, feed conversion ratio and survival of post-larvae Indian white shrimp, Penaeus indicus were evaluated in a 56-day study. The study was conducted in sixteen fiberglass tanks provided with aerated re- circulating water with four replicate tanks for each treatment. Twenty post larvae with a mean weight of 1.56 0.02g were hand-counted and stocked into each of the replicate tanks and fed 2, 4, 6 and 8 times a day, respectively. Final body weights were measured significantly lower at 2 and 4 times/day (5.76 0.08 and 5.96±0.15g, respectively) than 6 and 8 times/day (8.54±0.16 and 8.31 0.19g, respectively) treatments (P〈0.05). There were significant differences for the Feed Conversion Ratio (FCR) of shrimps fed 6 and 8 times/day with other treatments. The best mean FCR was obtained from the sixth daily-feeding (P〈0.05). The Specific Growth Rate (SGR) of shrimps fed 6 times/ day was significantly (P〈0.05) higher (3.03 0.04%) than shrimps fed with all other feeding regimes, while shrimps fed 8 times/ day had a higher SGR (2.95 0.05%) than shrimps fed 2 times/day (2.36 0.06%) and 4 times/day (2.39 0.11%). Survival rate was significantly different (P〈0.05). The best mean survival rate was obtained from 6 times/day feeding (P〈0.05). There were significant differences for survival rates (P〈0.05). The water quality parameters (salinity, dissolved oxygen and temperature) were not different among treatments. However, some water quality parameters (ammonium, nitrate, nitrite, phosphate and pH) were significantly different among the treatments. Results suggested that there was an advantage in feeding P. indicus more frequently than 4 times per day.

    Description: A four-week trial was conducted to evaluate the effects of different levels of dietary Betaine on growth, survival and resistance to salinity (35ppt), temperature (24 C), hypoxia and high and low pH stresses in rainbow trout (Oncorhynchus mykiss). Four levels of Betaine as 0 (control), 0.4% (B0.4), 0.8% (B0.8) and 1.2% (B1.2) were used with three replicates. Forty fish (0.67±0.15g) were stocked in each replicate and fed at 4-4.5% of body weight, five times daily. Results showed that there were significant differences in growth, survival, NPU, PER and FCR between B0.4, B1.2 and control diet (P〈0.05). Carcass analysis showed that there was higher protein in the carcass of fish fed with diet B0.4 compared to control and B1.2 diet. There were no significant differences in carcass protein content between B0.4 and B0.8. Also, no significant differences were found in carcass crude fat, ash and dry matter among different treatments (P〉0.05). Resistances to high and low pH (10.8 & 3.8) and to high temperature (24 C) were significantly better in fish fed with Betaine containing diets compared to the control diet. Resistance to high salinity in B0.4 was significantly better than the control diet and resistance to hypoxia in diet B0.8 was significantly better than the control (P〈0.05). The results showed that dietary supplementation of Betaine (0.4%) have positive effects on growth factors, survival, body composition and resistance to environmental stresses in rainbow trout.

    Description: The possibility of replacing fish meal with plant protein sources (soybean meal and corn gluten) for beluga (initial body mass 159.55±2.14g) was studied in autumn 2009. Experimental feeds with 46.5% of crude protein, GE: 5.4 Cal g -1 in four replacement levels: 0, 270, 450 and 660 gr kg 1 were prepared and fish were fed on the diets for 60 days. Significant differences were found in growth performance (P〈0.05) of different diets. Biomass gain, specific growth rate, feed conversion rate and protein efficiency ratio in fish feed with diet 1 was higher (P〈0.05) that the other ones. However, growth performance in diets 2 and 3 were not significantly different (P〉0.05). Moisture of beluga carcass fed with diet 4 was significantly higher (P〈0.05) that the other diets. However, protein, fat and ash were not significantly different (P〉0.05) among diets. The hematocrit percentage was significantly higher in experimental treatments 1 and 2 than 3 and 4 and the plasma glucose was significantly different between diets 1 and 4 (P〈0.05). With decreased fish meal, significantly (P〈0.05) decreased plasma cholesterol was found in diet 1 compared to the diets 3 and 4. Results showed that combination of soybean meal and corn gluten is not a good substitute for fish meal and deceased growth performance of the fish.

    Description: Stock assessment of edible bivalve, Solen brevis was carried out in Bushehr shoreline areas (50 21 E - 29 41 N to 52 41 E 27 17 N) throughout the period of September 2008 till September 2009. The objectives of this study were identifying the distribution, and estimating the abundance, growth parameters and natural mortality of the bivalve. Solen specimens were collected monthly in Bupatil area and from three other areas at low tide. On each transect one or two quadrats (0.25m 2) were placed at random. To estimate the stock abundance, the mean number of shells in each quadrat was regarded as an estimate of stock mean. Length frequency was used to estimate growth and natural mortality parameters. Data analysis was conducted with the most recent version of LFDA statistical software. The main distribution areas for live edible bivalve, Solen brevis, were located at Bupatil, Gasir, Kaloo, Piazi and Bordekhoon. The mean (±SD) abundance in Bupatil was estimated at 3.25 1.1 shells per quadrat with a maximum peak in October and minimum in August. The estimated growth parameters of this species was, K = 0.7 Year-1 , L = 120 mm and t0 = -0.35. Natural mortality rate (M) was estimated at 0.26 and the calculated maximum age (Tmax) was 54 months.

    Description: The present study investigated changes in growth and amino acid composition Kutum Rutilus frisii kutum during larval development. For this purpose, the periodic sampling from larvae obtained from breeders propagation was carried out at the fish aquaculture center of Shahid Rajaee in Sari. The samples were obtained at 1, 3, 7, 10, 15, 20, 25, 30, 35, 40 and 50 days after hatching (DAH). The result of larvae growth showed that mean initial and final length of Kutum (1 DAH, 50 DAH) were 8.47±0.02mm and 35.34±0.41mm, respectively. Initial and final weights were 4.02±0.01mg and 483.33±1.11mg, respectively. The composition of total amino acids of Kutum larvae changed significantly during ontogeny. High correlations were found between rotifers and dry food but correlations dry food was higher than that rotifer. No major imbalance was found in essential amino acids profile of the diet of fish larvae. Nevertheless, low correlation of rotifer to dry food in rotifer AA nutritional balances was less than dry food. During this study, methionine, lysine, arginine, threonine and histidine appeared to be limiting amino acids. These fatty acids showed the significant difference between the amino acid profile in larva and the diet.
