    Description: The purpose for which this study was intended wasto compare nutritive value among the farmed Vannamei, sea Green Tiger and Banana shrimps native to the PersianGulf.To provide the samples of farmed shrimps at the end of the farming season (Oct. 23rd through Nov. 22nd of 2011), we chosen one farm of the Holleh Shrimp Farming, from which 100 shrimps were randomly selected. From among these 100 shrimps, 3 to 5 ones were taken to conduct an analysis upon. Further, to obtain the Banana and Green Tiger shrimps sampling was done at the fishing season (July 23rd through Aug. 22rd of 2011) at Halileh Fishing Wharf located in Bushehr Fishing Harbor and also Bandar Abbas Wharf.The samples obtained were immediately kept in the ice powder. After some biometric tasks done upon them, they were at the shortest possible time transferred to a laboratory where they went through various experiments to determine their content of raw protein, fat, ash, moisture, various fatty acids and their types, cholesterol, vitamins A and E, and such mineral elements as iron and calcium. All the experimentswere carried out three times to establish confidence in the results to be obtained.Findings of the comparison showed the content of raw protein, fat, moisture, and ash of, respectively, 23.233%, 600%, 73.077% and 2.500% for the Vannamei samples, of 22.717%, 427%, 74.133% and 1.826% for our Banana shrimps and of 17.377%, 430%, 79.866% and 1.313% for the Green Tiger samples. A total of 24 fatty acids for the Vannamei shrimps and 27 for the Banana and Green Tiger were detected. SFA of the Banana shrimps was 368.45 mg/100g (51.76%), while those of the Vannamei and Green Tiger samples were observed, respectively, 363.54 mg/100g (37.26%) and 296.06 mg/100g (49.12%).A similar measurement for MUFA content of the three types of our samples revealed 243.85mg/100g (24.9%) for the Vannamei, 203.177 mg/100g (33.76%) for the Green Tiger and 179.033 mg/100g (25.14%) for the Banana shrimps. The content of PUFA unsaturated fatty acids in the Vannamei,131Green Tiger and Banana samples were, respectively, 370.660 mg/100g (37.84%), 101.573 mg/100g (16.9%) and 163.733 mg/100g (23.1%). Further, the comparison found a omega-3-fatty-acids total of 151.747 mg/100g(15.51%) for the Vannamei, 57.123 mg/100g (9.54%) for the Green Tiger and 130.460 mg/100g (18.46%) for the Banana species under study.

    Description: Morphological assessment of sexually mature Rutilus frisii kutum Kamenskii 1901 caught from the rivers (Shirud, Khoshkrud, Sepidrud and Chelavand Rivers) flowing in the southwest Caspian Sea region was conducted and sperm volume, total sperm count and sperm concentration of abnormal sperms were determined after exposing the spawners to 60% herbicide butachlor (machete). Spawners under study were maintained in tanks (1000 l) at the Shahid Ansari Teleost Fish Hatchery and exposed to two different concentrations (25% and 75% of its LC50 value) of butachlor.Results obtained indicate that exposure to high butachlor toxicity (75% of its LC50 value) decreased sperm volume to 0.61 ± 0.42 cc in 2-3 year old fishes and to 0.55 ± 0.42 cc in fishes above 3 years of age, while that in fish exposed to low butachlor toxicity (25% of its LC50 value) decreased to 1.55 ± 0.42 cc in 2-3 year old fishes and to 1.28 ± 0.42 cc in fishes above 3 years of age. The sperm volume under normal conditions in R. frisii kutum is 4.6 ± 0.42 cc in 2-3 year olds and 4.58 ± 0.42 cc in fishes above 3 years of age. The total sperm count in R. frisii kutum is 39.74 ± 2.5 billion spermatozoa/cc in 2-3 year olds and 42.99 ± 2.5 billion spermatozoa/cc in fishes above 3 years of age. When exposed to high butachlor toxicity, total sperm count dropped to 16.92 ± 2.5 billion spermatozoa/cc in 2-3 year olds and to 15.98 ± 2.5 billion spermatozoa/cc in fishes above 3 years of age. Similarly total sperm count in R. frisii kutum exposed to low butachlor toxicity was recorded as 23.6 ± 2.5 billion spermatozoa/cc in 2-3 year olds and 29.4 ± 2.5 billion spermatozoa/cc in fishes above 3 years of age. Under normal conditions, on the basis of morphology, spermatozoa showed only 10 ± 1.92% of abnormal sperms. The number ofabnormal sperms increased by 28.6 ± 1.92% in fishes exposed to high butachlor toxicity, while that in fishes exposed to low butachlor toxicity increased by 19.7 ± 1.92% in 2-3 year olds and 16.6 ± 19.2% in fishes above 3 years of age.It is evident from the results obtained that increase in level of pollution caused a decrease in sperm volume but an increase in the percentage of abnormal sperms.Results obtained indicate that exposure to high butachlor toxicity (75% of its LC50 value) decreased testostron hormone to 0.31 ± 0.22 ng/ml in high butachlor toxicity, and to 0.45 ± 0.22 ng/ml in low butachlor toxicity (25% of its LC50 value). Testostron hormone dropped to 0.53 ± 0.22 ng/ml in 2-3 year olds and to 0.79 ± 0.22ng/ in fishes above 3 years of age. The testostron hormone under normal conditions in R. frisii kutum is 2.7 ± 0.22 ng/ml.It is evident from the results obtained that increase in level of pollution caused a decrease in testostron hormone

    Description: As the most of the fish resources are known and exploited, protecting their generation is of the greatest importance. Aquaculture is one of the efficient procedures in protecting and reviving fish resources and knowing about the reproductive cycle and gonads development has an important role in approaching this aim.Liza abu belongs to the family Mugilidae that according to its resistance to the environmental condition and its fast growth , can be introduced as a fish with economical value. As there is no scientific data on the reproductive biology of this species , study on the reproductive biology and gonad development is considered as the aim of this research .For this purpose , 360 samples of this species were investigated during the period from February 2007 to January 2008 in Khozestan Province . After studing morphological and histological characteristics of gonad specimen , they were prepared through histological method. Samples were prepared through usual histological method and studied under light microscope.According to the results, the maturity stages of male and female Liza abu were separated to six different successive stages. In ovaries , these stages were as follow : In stage І, the oocytes were small , this stage was observed from July to October . In stage ІІ, considerable growth was observed in the oocytes . This stage was observed from October to January . In stage III, due to vitellogenesis, the maximum growth was observed and three layers of theca, granullosa and follicle cells were visible. This stage was observed during January and February . In stage IV, migration of germinal vesicle was observed and due to hydration of the oocytes , their diameter was increased. The ovaries were yellowish and in maximum size and ovules could be easily observed with naked-eye . This stage was observed in February and March . In stage V, spawning occured. This stage was observed in April . In stage VI, ovaries consisted of immature and atretic oocytes and also empty follicles. This stage was observed in May and June.In testes , these stages were as follow : In stage I , the testes were small in size and contained the spermatogonia which were the only cellular components.This stage was observed in August and September . In stage II (maturing virgin ) , the spermatogonia and the primary spermatocytes were visible. This stage was observed in October . In stage III (developing), intensive spermatogenesis was occured and the primary and the secondary spermatocytes were the most visible cells during this stage .This stage was observed from November to January. In stage IV(developed), cells of all stages of spermatogenesis could be seen but the secondary spermatocytes and spermatids were in large number. This stage was observed from January to March. In stage V , the testes were filled with sperms. This stage was observed in March and April .In stage VI, residual spermatozoa and the spermatogonia were visible in the testes. This stage was observed from May to August.According to cyclic changes in GSI, sexual maturation in breeding begins in January and spawning occurs in April. The ova diameter ranged from 30.75 μ in stage I to 472.19 μ in stage IV. In this study , the sex ratio was 1:2.7, and male and female percentage were 27.02% and 72.98% respectively. This means that females predominate males. In this study absolute fecundity was calculated and changing between 30805.44 to 431247.3 was observed and absolute fecundity was calculated 111275.3 in average.

    Description: In order to study of the artificial propagation efficiency in white fish (Coregonuslavaretus) and its fingerlings producing in IRAN, a 9 mounts study project was beendone which during it, the characteristics of the matures and brood stocks fishes, thecondition of their natural and artificial propagation, and the characteristics of producedfrys, were been studied. Throughout the total 82 pieces caught fishes during Septembertil February 2003, 10 pieces of them were the female brood stocks which during thecatch time did not have spouse. The study of these fishes showed that there was nosignificant correlation between their weight and their length. The most and the leastabsolute fecundity of these brood stocks were 19120 and 11496 respectively. Theartificial propagation was been done by 5 males and 4 females broods took which57602 ova, with 89/2% fertilization rate, earned from them. The incubation periodprolonged 55 days in 8°c. At the end of the incubation, 23913 larvae released. So theartificial propagation efficiency was calculated 41/51% in this study. Yolk sackabsorption prolonged 4 days. 3 different food treatment were considered for frybreeding which contain of Brachiouns plicatilis as live food, salmon starter food ascommercial food, and the mixed of equal amounts of live and commercial foods as thirdtreatment. For each treatment, 3 repeat has been considered. Breeding durationprolonged 13 weeks throughout this period, different characteristics of fry were beenstudied weekly. The breeding results showed that there was very significant correlationbetween the weight and the length of frys. However the live food provided better resultsin growth and survival rate of frys during breeding initial 6 weeks.More ever, commercial food, in some characteristics, provided more acceptable resultsin comparing the live food after sixth week. The results of this study project showedthat the artificial propagation in whitefish is possible in IRAN and the producing of itsfrys in order to restocking or introducing this species to the other Iranian suitable waterresources is executable. Based on the earned information from this study, the suitabletime for natural spawning of whitefish in IRAN (Amirkabir dam lake) determinedbetween 10th January til 20th February.

    Description: The Moosa Creek extends from its opening into the Persian Gulf, with some sub narrow creeksleading to it. Zangi creek is one of the main branches of Moosa creek. The creek containsnumerous sources of organic pollution, including sewage outlet flows and boat waste. Afterestablishing the Petrochemical special Economic Zone (PETZONE) in 1997 near to the ZangiCreek, the pipelines, streets and railway made it distinct from eastern and western parts of thiscreek. Industrial activities have released sludge and effluents in this creek along these years. Asurvey of the Zangi creek was performed, assessing water properties, organic pollution, and thepopulation density, distribution and diversity of macrobenthic fauna through bi-monthlysampling from July 2006 to September 2007.Samples were collected from water near the bottom and sediment at 7 stations include 2 stationsinside the distinct Zangi creek and 4 stations along a transect with 1 km distances between themin eastern free part and one reference station located at the Persian Gulf entrance to the Moosacreek. The environmental parameters such as temperature, salinity, pH, dissolved oxygen, COD,turbidity, EC and heavy metals include Hg, Cd, Pb, Ni as well as percentage silt-clay and totalorganic matter of the sediment were measured. The faunal population density and theirdistribution are discussed in relation to the environmental changes.Results showed spatial heterogeneity in faunal distribution of the Zangi creek. Nine groups ofmacrofauna were identified out of distinct zangi creek. Polychaets formed the dominant group(48%) followed by bivalves (13%), gastropods (10%), Decapods (2%), Tanaids (5%), and allother groups (22%). The distinct creek was heavily polluted without any macrofaunacommunities probably as a consequence of the high pH, COD, low salinity and heavy metalscontamination specially Cd and Pb. The other stations near to the disposal site were found withmacrofauna communities commonly tolerant to organic pollution, At 3 km east of the disposalsite, macrofauna is comparable to the surrounded creek, whereas macrofauna still indicateenvironmental degradation. Farther a way, faunal density decreases and equilibrium taxagradually replace opportunistic species, while the other stations were far from polluted areacontained lower pollution and relatively healthy macrofauna.The mean biomass of macrobenthic fauna were estimated for the whole studied area. The resultsare considered in Minimum density and biomass in surrounded creek and maximum density andbiomass in 3 km of surrounded area. Biodiversity Indices were low in surrounded creek. TheShanon-weaver information index was used to describe the spatially variations in diversity.Macrofauna density, shanon and simpson index were significantly variable between surroundedand free parts of Zangi creek (p〈0.05). The numerical abundance of macrobenthose varied from221. m-2 in polluted area to 4346 m-2 in free part of Zangi creek. The Shanon-weaver informationindex varied from 0.4 in distinct area to 2.9 in reference station.The physico- chemical changes between distinct and free creeks showed significant variationssuch as pH, salinity and EC. Salinity and EC were significantly positive correlate to macrofaunadensity, whereas pH and TOM percentage indicated significantly negative correlation to density.Heavy metals concentrations in sediments were higher than water samples. Concentration patternof heavy metals in sediments and water samples were Ni〉Pb〉Cd〉Hg. Salinity and pHwere significantly correlated to metals in sediments (p〈0.01).No significant correlation were found between Macrofauna density and heavy metals (p〈0.05).

    Description: Ozone due to having low half-life and devoid of environmental harmful effects is recognized as one of the most effective disinfectant and fungicide in aquaculture. The objective of this study is to consider the effects of periodicay ozonation, hydrogen peroxide treatment, and physical treatment capability in hatching rate enhancement. Three concentrations of 0.05, 0.1 and 0.15 ppm ozone (10 min) and peroxide hydrogen with dose of 500 and 1000 ppm in two procedures accompanied with physical treatment and without physical treatment were examined on hatching rate. In the first year, Egg ozonation (0.1 ppm) with physical treatment have been resulted the greatest hatching rate (81.4%). In the second year, egg treatment with 1000 ppm hydrogen peroxide with physical treatment have been showed the greatest hatching rate (78%). Average hatching rate for the blank control treatment (without disinfectin and physical treatment) was 32.7%. From the economic viewpoint, 0.05 ppm ozone with physical treatment, due to considerable minimizing at consumption energy and ozonation system retention costs, indicated as the best treatment than other ozone treatments for fungal control. Very low correlation (r=-0.14) have been observed between hatchery water temperature and fungal infection percentage in control treatment.

    Description: A 3x3 factorial experiment was conducted to determine the optimum protein to energy (P/E) ratio for rainbow trout in brackish water. Three crud protein levels and three energy levels at each protein level were utilized. Diets were made in semi-purified that in all of them fish meal, casein and gelatin as the sources of protein and dextrin, starch and oil as the sources of energy were used. Each of experimental diets was fed to triplicate groups of 20 fish with an average individual weight of 81.5 g in 9 2000-1 flow trough fiberglass tanks. During this experiment water temperature, dissolved oxygen, PH and EC were 15±2°C, 6.5-8.1 mg/1, 7.7-8.6 and 25400 grills respectively. The diets were fed at a rate between 1.6-2 wet body weight% per day depended to water temperature in three equal rations and adjusted two weekly for 84 days. At each of protein levels, weight gain percent (%WG), average daily growth percent (%ADG), protein efficiency ratio (PER), apparent net protein utilization percent (%ANPU), or percent of protein deposited, specific growth rate (SGR) and condition factor (CF) were found to increase and food conversion ratio (FCR) was found to decrease with an increasing energy levels from 370 to 430 Kcal/100g. Fish fed a 35% protein, 430 Kcal/100g energy diet with a P/E ratio of 81.4 mg protein/ Kcal PFV energy, attained the best growth performance. Fat and moisture of carcass were affected by protein and energy levels of test diets while protein and ash of carcass were relatively constant in different treatments.

    Description: The present study with headline investigation on reproduction in two species of Crab Eriphia sebana and Ocypode saratan was carried out in the intertidal zone of Chabahar in thirteen month from December 2004 to December 2005. Checked samplings have been taken, 45 number Crab monthly from any four stations by manual or use trap. During this study the following subjects were measured: Temperature range and salinity, Measurable coast granule, Determination of sex ratio, Relations carapace width with carapace length, Carapace width with total body weight, Gonad weight, gonadosomatic index, condition factor, gastrosomatic index, investigation content in stomach, LM50, Growth parameters, plenty distribution length and width and gonad weight and total body weight. Studied on measurable coast granule were expressed that Ocypode saratan in Desalination station, were nest in soils equable sand and this quantity were confirmed in Pozm station. Sex ratio were assign in desalination area and Pozm M: F 0/44:0/56 and in Tiss and Chabahar M: F 0/45:0/55. Carapace length and carapace width (cm) and body weight (g) Furthest were designated in Ocypode saratan within carapace width sequential: female: 5/42-6/15-105/13 and male: 5/53-6/25-108/91 and in Eriphia sebana within Tiss area sequential: female: 5/12-5/94-110/21 and male 5/14-60/01-114/37. Have been linear relationship between carapace length and carapace width and equaled CW = a CL + b. Weight growth in two species were be modal and equaled BW= aCLb and increased Crab weight by built up carapace width. Maximum gonad weight in Ocypode saratan within desalination area in female have been outcome 3/39 and in male 0/84g and in Eriphia sebana extreme within Tiss during may in female were be 4/18 and in male 1/1g. Stomach content in Eriphia sebana were involved a black until half-purplish liquid and yellowish in Ocypode saratan. Stomach contents identifiable were being in four groups: Molluscoid, Crustacean, Plankton and Fish. Carapace width during the first year of maturation have been LM50:3/77 in Desalination area and LM50:3/92 in Pozm for Ocypode saratan and LM50:4/26 in Tiss and LM50:4/62 in Chabahar. Ability spawning in Eriphia sebana within Tiss has been CW=4/17cm and in Ocypode saratan within Desalination area CW=4/23cm. Maximun value of Loo for Eriphia sebana was equal 59/67 and growth factor K=0/68 within Tiss and Loo =61/64 , K=0/65 for Ocypode saratan within Desalination area. Maximun GSI and GI have been within Desalination area and Tiss and minimum within Pozm and Chabahar. The maturity stages of two species were classifed into six stages. Review on GSI, CF have been showed that relation with temperature and salinity and definer in two species have been spawned in two period that Maximun in spring premier than autumn.

    Description: In order to study caudal fin rot with emphasis on Aeromonas hydrophila and Pseudomonas fluorescens in Salmo trutta caspius from the salmonids propagation and breeding center of Shahid Bahonar of kelardasht region, One hundred and eighty brood stocks having fin damage symptoms were chosen. Two bacterial samples from each fish were cultured on Aeromonas and Pseudomonas specific media. Biochemical tests, API2OE identification system and antibiogram test using six antibiotic disks were performed for diagnosing isolates bacteria and finding suitable antibiotic. Thirty samples from caudal fin of damaged fishes were fixed in 10% formalin and 51.tm microscopic sections were prepared using standard scatological methods and then stained by Haematoxylin-Eosin staining method to observe the pathological changes and also Maccallum-Goodpasture staining method to observe the bacterial colonies. In second stage of the study, bacterial samples were taken from thirty brood stocks using similar method at the first stage of sampling. For isolation and biochemical diagnosis of Aeromonas and Pseudormonas genus, the samples were analyzed by molecular research included PCR amplification (using 16S rDNA genes of the genus pseudomonas and 16S-23S rDNA intergenic spacer of the genus Aeromonas) and restriction analysis by four restriction enzymes for each genus. The results of biochemical tests showed that isolated bacteria were belonged to Aeromonas caviae and Aeromonas hydrophila (subspecies anaerogenes), Pseudomonas fluorescens, Pseudomonas putida and Pseudomonas alcaligenes while the results of API2OE identification system showed that the isolated bacteria belonged to Aeromonas hydrophila, Pseudomonas fluorescens, Pseudomonas putida and Pseudomonas aeruginosa. Restriction analysis of Aeromonas samples with Hin6l, Csp6I, Taql, and Tasl revealed three samples were different from others while restriction analysis of Pseudomonas samples with Alul, Hinfl, Rsal, and Trull showed at least five species or biovars. The results of antibiogram test showed all Aeromonas samples were sensitive to Trimethoprim, Chloramphenicol and Nitrofurazone, mostly to Nalidixic acid and Chloramphenicol, while most of samples were resistant to Erythromycin and Oxytetracycline. Pseudomonas samples were only sensitive to Nitrofurazone and mostly resistant to Oxytetracycline, Nalidixic acid, Erythromycin, Trimethoprim and Chloramphenicol. The results of light microscope study showed hyperplasia and spongiosis of the malpigian cells of epidermis, increasing of melanin pigments underlying epidermis; sever necrosis in both epidermis and dermis and also sloughing the epidermis in some cases. Occurrence of clefts through the epithelium, neovascularization, hyperemia and mild inflammatory response in dermis and separation of the fin rays also were observed. No bacterial colonies were found in the sections.

    Description: This study investigated the pathological changes of heart and bulbus artrius of rainbow trout breeders in several group of ages and density. The aim of study was to consider the process and the intensity of the heart and bulbus arteriosus damages in accordance to gender, age and stocking density of trout in three fish culture center (Zarghezel, Niyak in Haraz Region,Mazandaran and Espiran in Tabriz city environs). In field research, the all records the feed and feeding type, rate of mortality, stocking density of spawners and per spawners fishes, water chemical and physical specification was screened. Stocking density was considered as the most important stressor. 10 fish specimens from 7 weight groups (less than 90g, 90 to 300g, 300 to 500 g, 500 to 1000g, 1 to 3 kg, 3 to 5 kg, over 5 kg), totally 210 specimens were sampled and heart and bulbus arteriosus were taken. Samples were fixed in 10 % formalin and transferred to pathology laboratory of veterinary faculty of Tabriz Azad University. Histopathological slides and H&E staining were prepared from these samples. In total, 47 male and 73 female samples showed cardiovascular injury (29 cases in extensive system, 41 cases in semi intensive system, 50 cases in intensive system). The most important was damages, edema and hyperemia in spongy layer of atrium and ventricle muscles, but degeneration the muscle fibers, moderate edema , minor vascular damage. Hemorrhage as the effect of severs vascular damage, thrombus, sever inflammation, sever degeneration in muscle fiber, necrosis and fibrose were further pathological changed. The results of this study showed that the severity of damage increased by increasing the age (weight) of fishes. This situation was seen in all three culturing system (extensive system, semi intensive system, recirculation system). Histopathological changes is obviously seen in samples over 500g, therefore the damages were found to be important (P〈0.05). Pathological effects and its severity in recirculation system was significantly high (P〈0.05). Comparison with two other culturing system, histopathological changed in heart and bulbus arterius between male and female was significantly different.

    Description: Lake Ovan with about 9 hectares is regarded a semi-shallow lake with an average depth 5.2 meter. It is situated in Ghazvin Province, with a 1910 m high in mountainous regime. A monthly sampling was done at 3 stations studying the physicochemical and biological parameters in water and sediment at the Lake for a year. The temperature annual was measured 12.3°C and other parameters are pH as 8.8, oxygen 10, with total mean phosphate and nitrate as 0.14 & 0.8 mg/lit respectively. The chl.a mean was also measured 1.94 mg/lit. The ratio of N to P was calculated as 1:59, indicating a limiting factor for growth. Considering the trophic statues of the lake taking into account as above parameters, it is a mesotrophic lake with medium trophy. Altogether, 53 phytoplankton species were identified mostly diatoms, green algae and cyanobacteria. Although, 14 zooplankton species were identified with daphnia dominating the group. Macrobenthoses were also surveyed and 11 families were identified comprising mainly by Annelids, Gastropod, Bivalves and Insect Larvae. Other organisms were 2 dominate water plant including Phragmites australis covering at the edge of the lake and potamogeton sp in the inner parts, and also 2 fish species, common carp and Pike Perch. The diversity Shannon—Wiener index was calculated for main taxa groups with all figures lower than 3. Regarding the fish potential production of the lake based on Bramic & Lemke and morphoedophic index, it was calculated to be 20.4 kg/ha fish and a total of about 150 kg for the entire lake.

    Description: Cold smoking method is one of the commonest ways for fish smoking. It is done by the smoke that is the result of burning hard and soft woods is smoking rooms. Smoke includes a number of chemical constructs and its main part is poly aromatic hydrocarbons. More than one hundred kinds of these constructs are recognized in smoke that is produced from saturated hydrocarbons resulted from the solution of the woods Ligno cellulose in high temperature and lack of oxygen conditions. The high poisoning potentials and carcinogenic features sixteen constructs among them are proved and observed on humans. In this research, the PAH compounds were identified and observed in a three month period after smoking and during storing among three types of smoked fishes Silver carp and Caspian sea Sefid and herring. They are the most produced and consumed smoked fish in Iran. To find the relationship between the concentrations of PAH constructs and the amount of lipid in fish, first, the amount of lipid were determined separately in the skin and flesh of 30 samples of each type. The method used was Bligh and Dyer (1959). PAH compounds derivation were made for all skin and flesh samples smoked fish using organic solvents with Soxeleh and the derived samples were injected to gas chromatography (GC) by Hamilton injectors for determining their components quality and their quantity. The height of the used column was 25 meters and its diameter was 0.32 mm with the silica filler, nitrogen gas as carrier and flame ionization detector (FID) that are special for these constructs. For data analysis, Statistical tests were used by computer soft ware identified that the difference in the amount of lipid within the flesh and skin of each species and also among each other is significant. The largest amount was in Herrings flesh and skin, 18.74% in skin and 14.47% in flesh. The least amount in the skin 4.19% and the flesh 3.10% of Sefid. The amount in Silver carp was 13.28%in skin and 8.16% in flesh. The examination of the PAH compounds in smoked fish showed that is carcinogenic compounds; exist in these in these fish with different quantities in each. It seems that its amount is directly related to the amount of their lipid. The amount is different in flesh and skin. One of the most important reasons is the direct content of smoke and the concentration of lipid in tissues of all three types. The maintenance of the smoked fish for three months showed that most of PAH compounds were solved and their density decreased. The changes in density within time in different in each type and in flesh and skin. The amount of their receiving in human through the consumption of the smoked fish depends on the resulted density, the way and the amount of consumption and now we can determine and execute standards for the maximum dosage per day and per month regarding effective factors.

    Description: Streptococci are gram-positive cocci, sometimes coccobacilli, arranged in chains. This group of streptococci resides in the intestine of warm-blooded animals. They are bile resistant and capable of growth at 45°C. Fecal streptococci form part of the microflora of many foods without necessarily indicating poor hygiene. They are found in many fermented foods, such as cheese and raw sausage, and often take part in the fermentation process. However, in meat products which have received a severe heat process, the presence of excess numbers of fecal streptococci indicates unhygienic handling and/or faulty storage. Presented in the paper is the methodology of determining the presence of fecal streptococci in fish and fishery products.

    Description: Fish consumption in Japan is very high compared with other countries; it is approximately 96 g daily per capita and provides a good balance of protein, fats and oils, and carbohydrates. The largest component of the fish catch in Japan is sardine; attempts are being made to produce new products, other than the traditional forms, such as surumi. In fatty sardine fish, the characteristic components include polyunsaturated fatty acids which lower the blood cholesterol levels; in particular eicosapentaenoic acid lowers the incidence of adult diseases such as myocardial infarction.

Although some problems exist, monitoring operations have been proceeding successfully. Investigations concerning various aspects of shellfish poisoning are being conducted by 6 national institutions, 15 universities, and about 30 fisheries laboratories. Because shellfish poisoning is a kind of natural phenomenon, the only defense is the establishment of precise monitoring techniques to reduce damages. Efforts to improve monitoring, however, need to be carried out through fundamental research.

    Description: Hilsa shad, Tenuolosa ilisha, belongs to Clupeidae family and Alsinae subfamily isan euryhaline pelagic and anadromous species living in marine and freshwaterwaters.Regarding to study the biological characteristics of this species, this study wascarried out in the Northern Persian Gulf within Bushehr province waters duringyears 2006-7.A total of 344 specimens were collected and transported to the laboratory forfurther different biological measurements consist of: reproduction (GSI, fecundity,maturity stages), feeding (stomach contents, food preference ...), aging; 58morphometric and ٧ meristic measurements.The results indicate that minimum, maximum and mean body weight are 203, 953 and 481.35±147.64 g, respectively and this values for total length are 26.5, 45.1 and 35.99±3.98 cm. For food regimes, the most abundant phytoplankton foodsbelong to Bacillariophyta (83.74٪) and zooplanktons of Arthropoda (51٪). Themean RLG was measured about 1.53±0.22 and the mean feeding intensity wasabout 51.79±38.13. Also, the aging of studied fishes showed that they have 2 to 4 years and most of the samples had 2+ years.The reproduction studies showed that Indian shad is a batch spawner species. The average gonadosomatic index (GSI) is 1.64±1.382 and the main spawning season was determined for April-May.

    Description: Use of prebiotics, nondigestible dietary ingredients that beneficially affect the hostby selectively stimulating the growth of and/or activating the metabolism of healthpromotingbacteria in the intestinal tract, is a novel concept in aquaculture. An8-week feeding experiment was conducted to investigate the effects of dietaryprebiotic inulin on the growth performance, intestinal bacterial density, bodycomposition and values of blood serum enzymes in the juvenile great sturgeon(Huso huso). Three replicate groups of fish (initially averaging weight 16.14±0.38g) were fed diets containing prebiotic inulin at levels ranging from 1% to 3%. Thebasal diet was contained 3% cellulose. The results of linear regression showed therewas a negative relationship between some performance indices including weightgain (WG), specific growth rate (SGR), protein efficiency ratio (PER), net proteinutilization (NPU), energy retention (ERE), feed efficincy (FE), protein retention(PR) and supplementation level of inulin. At the end of trial, the 1% inulintreatment insignificantly showed an enhaced survival between the treatment groups.Intestinal lactic acid bacteria (LAB) increased in group treated with 1% inulincompare to other groups. No significant difference were observed in bodycomposition and level of serum enzymes (P〉0.05). Moreover there was significantcorrelation between ALT and LDH values (P〈0.01). Result obtained in this studyshows that the prebiotic inulin didn’t influence the increase of the growthperformance of juvenile great sturgeon and it is not appropriate for supplementationin the diet of beluga.

    Description: Phytoplankton productivity is the common and important factor being considered indetermining the overall status of a given body of water. This is because they are found atthe base of an energy or food chain, being the basic source of primary food in a givenaquatic system. Hence, information on their contribution is essential in indicating howmuch biomass energy will be available to all other living resources in the system. Thoughthe primary productivity of shallow lakes is characterized by mixed populations ofphytoplankton and submersed aquatic vegetation in the open water. Lake Choghakhor, is ashallow lake, located in Chaharmahal-Bakhtiyari Province. This lake is the mostimportant ecosystem in the region especially for waterfowl populations, has a recreationalvalue and supports tourism and fisheries. During last decade Choghakhor has beeninfluenced by some man-made impacts such as water level fluctuation, agriculturaldischarge and fish (Cyprinids) introduction causing a serious problem in its trophic states.So water quality for physical, chemical and biological was monitored in five samplingstations, from April 2003 to March 2004. As biological parameters we studiedphytoplankton, epiphytic algae, and zooplankton and macrobenthose community structure.Chlorophyll a content for phytoplankton and epiphytes was measured to estimateproduction of these groups (biomass over time).Also we determined biomasses of submersed macrophytes and macrobenthose and primaryproduction of phytoplankton (dark and light bottles technique) to estimate fish production.The results of this study showed Lake Choghakhor did not undergo stable thermal andoxygen stratification, and the lake water was mixed throughout the study (the lake mixingregime is polymictic). Now submerged plants especially Myriophyllum spicatum has coveredalmost the entire lake and dense macrophyte beds (Polygonom amphibium), located on theeast southern end of the lake appear to act as a sink for these nutrients. Lake Choghakhorappeared to be in a macrophyte dominated clear water state with low TP (annual mean:24± 15μg.l-1) and chlorophyll a (annual mean: 3±1.28μg.l-1) concentrations and very highSecchi depth. The grazing pressure of dominant pelagic filtering zooplankton Daphnialongespina did not seem to be significant in determining the low phytoplankton cropexpressed as chlorophyll a. We expect that sequestering of nutrients by submerged plantsand associated epiphytes are the dominant stabilizing mechanisms suppressing thephytoplankton crop of Lake Choghakhor.

    Description: The first aim of this research was to identify fatty acids, amino acids composition of Thunnustonggol roe and their changes during cold storage (-18'C). The second aim was to determinethe changes of moisture, protein, fat and ash contents of the roe during one year cold storage(-18'C). 60 samples of longtail tuna (Thunnus tonggol) ovaries were randomly collected formBandar-e-Abbas landings. The samples were frozen at-30'C and kept in cold store at -18'Cfor one year. According to a time table, the samples were examined for identification offatty acids, amino acids, moisture, protein, fat, ash, peroxide and T.V.N. and their changeswere evaluated during this time. The results showed that 26 fatty acids were identified. Theunsaturated fatty acids (UFA) and saturated fatty acids (SFA) were 62.33 and 37.6%,respectively, in fresh roe. So that, DHA (C22:6) and oleic acid (C18:1) had high amounts(24.79 and 21.88%) among the UFA and palmitic acid (C16:0) was the most content(22.75%) among the SFA. The PUFA/SFA was 0.91. Also, 17 amino acids were identifiedthat essential amino acids (EAA) and nonessential amino acids (NE) were 10478 and 7562mg/100g, respectively, and E/NE was 1.38. Among the EAA and NE, lysine (2110mg/100g)and aspartic acid (1924 mg/100g) were the most contents. Also, results showed that moisture,ash, protein and fat contents were 72.74, 1.8, 19.88 and 4.53%, respectively, in fresh roe. Theeffects of freezing and cold storage on the roes showed that UFA and SFA contents havereached to 49.83 and 48.07%, respectively, at the end of cold storage. It indicated that thesecompounds change to each other during frozen storage. Also, n-3 and n-6 series of fattyacids were 32.75 and 1.61% in fresh roe. But their contents decreased to 22.96 and 1.25% atthe end of period. Among the fatty acids, 22:6 and C16:0 had the most changes. The changesof fatty acids were significantly at 95% level except for C15:1, C18:3(n-3) and C20:4(n-6).All of the amino acids decreased in frozen storage and their changes were significantly(P〈0.05). EAA was 7818 mg/100g and E/NE was 1.27 at the end of storage period. Amongthe amino acids, leucine and lysine had the most changes. Moisture, ash, protein and fatcontents were 70.13, 1.82, 19.4 and 6.51%, respectively, at the end of storage period. Theperoxide value and T.V.N. increased during storage. So that, their contents have reached to5.86 mg/kg and 26.37 mg/100 g, respectively, at the end of frozen storage. The best shelf lifeof Thunnus tonggol roe was 6 or 7 months, because of lipid oxidation and increasing ofperoxide.

Concerning its role in fisheries economic, various research projects on stock assessment, biology and aquaculture has been conducted. This research is targeted the identification of various populations of green tiger prawn in northern waters of Persian Gulf. The area has been divided to five regions from north to south named; Bahrakan, Boushehr, Tangestan, Motaaf and Strait of Hormoz. In each region, numbers of sampling stations trawled, and live shrimp species carried in containers equipped with air pump, to coastal laboratories in Boushehr and Bandar Abbass Fisheries Research Centers. Biometeric, morphometeric and merestic measures for 45 factars done, and peices of muscles, eye and ovary tissues dissected, and stored in liquid nitrogen. Protein extraction, and polyacrylamid gel electrophoresis by SDS-PAGE technique for tissues samples conducted. Data of 45 morphometeric and merestic characteristics analyzed by principal component analysis (PCA), and clustering analysis methods. The results of analysis showed that, the populations of Bahrakan and Mota.af regions are differentiated, while population of Boushehr and Tangestan regions were mixed, and named as a single population. The analysis of electrophoretic data also confirmed this result, and showed a distinct population in Strait of Hormoz. Therefore, this research illustrated four distinct populations for P. semisulcatus in northern area of Persian Gulf, named Bahrakan (north of Boushehr), Boushehr and Tangesta.n (adjacent), Motaaf and it's south, and Strait of Hormoz.

    Description: The pharaoh Cuttlefish (Sepia Pharaonis) is the most abundant species in the persian gulf and oman sea. The stock patterns of this species was studied conserning biological, morphological and electrophoretical aspects. In addition to measuring the biological patterns; 21 quantitative and qualitative factors were measured or counted. There tissues namely muscle, eye and liver were also used for further polyacrylamide electrophoresis analysis (SDS-Page method). The densitograms of protein bands of each tissue were prepared by Gel-Scanner and also the amount of bands' areas were estimated. The results of LSD test showed that tentacle length (TL), Tentacle club length (TCL) and TCL were indicative factors which they showed significant difference between male TL and female specimen of Bushehr and Balouchestan regions. Regarding to length and weight frequencies data the results indicated that males are always bigger than females and also, the cuttlefishes of the gulf of oman are bigger than persian gulf's samples. There were found a significant sample correlation (95%) between different quantitative parameters and the most correlation (0.963) was found to be between TL and TCL; whereas the less correlation (0.384) was observed between GL and LA3. However the gill length factor illustrated the less correlation with the other factors. The results of Cluster analysis for both sexes showed that the cuttlefishes of both studied regions belongs to seperate stocks. The electrophoretic experiments of proteins showed that the protein bands of the sample tissue of muscle and eye from both sampling areas revealed significant differences; whereas the tissue of liver wasn't recognized as an indicative tissue for population studies. Taking into consideration the findings of the present study including: (1) difference in spawning season, (2) results of dendrograms, (3) observed Significant differences in one-way analysis of variance (ANOVA) for morphometric measurements, (4) differences in body length and weight, (5) ecological variations of the persian gulf and oman sea, (6) as well as the results of electrophoresis of proteins have indicatend that: "The Pharaoh cuttlefishes of Bushehr and Balouchestan waters belong to two seperate stocks. Also, it is believed that each region has propably two different populations and more studies are needed to approve this result.

    Description: This is especially well supported by down core variation Zn concentration. As Caspian Sea water intrudes into the Bay, it may be concluded that some part of pollution has sea origin. The geochemical index (Igeo) was reformulated for the area of study using chemical partitioning as well as Pb-210 results. The newly developed geochemical index is indicative of low to medium pollution intensity in the Bay of Gorgan. Thus, any additional pollution into the area of study may leave adverse effects on the aquatic ecology of Bay of Gorgan. Further, lithogenous and non-lithogenous inputs of metals into the Bay were assessed. For this purpose and through chemical partitioning, association of metals with different sedimentary phases was determined. The overall results show that about 114th total metal concentration have been added into the Bay of Gorgan through human activities.

    Description: Studies on the development of value-added products using arrow squid (Loligo sp.) and bullet tuna (Auxis rocheii, R.) were conducted. The recommended steps in new product development were systematically followed while establishing control to all steps in these product development studies to ensure that the requirements for quality fishery products are met. New product concepts were generated, evaluated, and refined. The most plausible concepts were then advanced to the product optimization stage wherein samples were subjected to a series of sensory evaluations to come up with the standardized formulations. Three (3) squid products, namely squid nuggets, squid loaf, and squid rolls, and two (2) bullet tuna products, namely tuna loaf and dried seasoned tuna, were then subjected to either accelerated or actual shelf life testings, consumer acceptability testings, and cost analyses. In collaboration with a private company, the most promising technologies generated from the preceding activities were advanced to pilot-scale production in which the HACCP-concept of quality assurance was applied, and the hazards and critical control points associated with each step in the production of the new products were established. The resulting products were finally subjected to consumer testing at the Japan Food Expo '95 which proved their acceptability to the export market as well as the products' feasibility for commercialization.

    Description: Frozen surimi has been a major export fishery product of Thailand for many years. Approximately 70% of its total production is exported to Japan, while the remaining is locally used and exported to France, Korea, Taiwan and Singapore. Although surimi is not categorized as a high risk item, as it is not a ready-to-consume product but prepared to serve as a raw material for a variety of surimi-based products, it still needs to meet the minimum requirements of product safety control. In this study, the quality assurance program is established for the Thai surimi industry. The guidelines are prepared and based upon risk assessment and potential health hazard identification associated with routine surimi production, from the point where raw material is received at the plant, through the line processing steps, and ending with the finished product s transportation. Besides the Hazard Analysis and Critical Control Point (HACCP) principles applied in this program, Good Manufacturing Practices and sanitation standard operating program are also added to strengthen the aim of assurance in food safety.

    Utilization of lizardfish, Saurida tumbil, for surimi production (2021)
    Marine Fisheries Research Department, Southeast Asian Fisheries Development Center | Singapore
    In:  http://aquaticcommons.org/id/eprint/26705 | 23782 | 2019-08-29 08:02:13 | 26705 | Southeast Asian Fisheries Development Center, Marine Fisheries Research Department

    Description: Lizardfish, Saurida tumbil, is an abundant resource that is relatively underutilized. It is a potential raw material for surimi processing. Characterized by its ability to produce formaldehyde endogenously after catch, the lizardfish tends to have comparatively higher levels of formaldehyde, which is known to accelerate protein denaturation. As such minced meat from lizardfish has to be treated to enhance its gel-forming ability. The objective of this project is to improve the gel-forming ability of surimi made from fresh and frozen lizardfish by sodium pyrophosphate leaching (PL), and the use of egg white and beef-plasma protein concentrate. This was compared against the usual leaching (UL) method. Pyrophosphate leaching (PL) resulted in better gel-forming ability. Two-times of leaching using 0.2% sodium pyrophosphate resulted in the production of reasonably good quality fish jelly products from fresh and frozen lizardfish. Both egg white and beef-plasma protein concentrate improved the gel-forming ability of surimi from lizardfish. However, if the frozen raw material is of poor quality, neither pyrophosphate leaching nor the addition of egg-white or beef-plasma could improve the gel-forming ability of the surimi. The critical control point for raw material quality is its formaldehyde level. The best quality surimi is obtained when the formaldehyde level is below 15 ppm.

    Description: Natural and liquid smoking of striped catfish (Pangasius sutchi), chub mackerel (Rastrelliger brachysonus), squid (Loligo edulis) and green mussel (Mytilus viridis) were compared to evaluate the feasibility of liquid smoking of these products. The appropriate brine concentration and brining time as well as liquid smoke concentration and soaking time for each product were determined. The acceptability of these smoked products was tested by sensory evaluation using a nine-point hedonic scale. The characteristics of the products judged were colour, flavour, odour, texture and overall acceptability. A panel of 14 judges was drawn from the faculty members and students of the Department of Fishery Products, Faculty of Fisheries. The results were statistically analyzed using Student s t-test. The appropriate brine concentration and brining time for striped catfish, chub mackerel, squid and green mussel were 15% for 7 min; 20% for 30 min; 15% for 10 min and 5% for 4 min, respectively. The suitable liquid smoke concentration and soaking time for striped catfish and chub mackerel were 10% for 15 min; for squid and green mussel the appropriate concentration and soaking time were 6% for 15 min and 1% for 2 min respectively. The sensory evaluation scores of both natural and liquid smoked products were comparable. The scores for colour, flavour, odour, texture and overall acceptability of striped catfish, chub mackerel and green mussel were not significantly different. However, the score for odour of liquid smoked squid was significantly lower than that of natural smoked squid (P=0.05) but all other characteristic scores were not significantly different.

    Description: The K value, expressed as K value % = HxR + Hx /ATP + ADP + AMP + IMP + HxR + Hx x 100 is a good index for estimating the enzymatic freshness of fish. The changes in K value of various species of tropical food fishes during ice-storage had been studied. It was found that these warm water fishes deteriorate slowly under ice-storage preservation. A study was made on the K value changes of three species of fish (Polynemus sp., Rastrelliger kanagurta and Pampus argenteus) in a supermarket distribution chain. Most sets of data showed changes of quality; from the point of supply until the morning after an overnight stay on display shelves. The results support a conclusion that the shelf life limit of fresh tropical food fish, based on sensory evaluation, was, when handled well, between 12 to 28 days ice-storage depending on species, with the K value ranging from 24 -37%.

    Description: An assessment was carried out on histamine content of three canning factories. These factories are located in East Java (A), Bali (B) and North Sulawesi (C). Histamine contents were assessed along various stages of their processing. Results showed that histamine contents changed during processing of canned tuna in both A and B factories and that they increased significantly especially after steaming. In contrast, decreasing histamine content was noted during processing of canned tuna at factory C. These results seem to stem from the fact that a lot of raw material was processed by factories A and B. Histamine was probably produced during delays along the processing line. This was in contrast to factory C in which a special tuna fish was processed for the study and only a small quantity of fish was going through at the time.
