    Description: Tue south Caspian subbasin extends from the foot of the Alborz Mountains to the deepest part of Caspian Sea. The Jithological background and tectonic setting of the study area primarily control the deposition ofthick sedimentary sequences of the basin, while hydroclimatic processes exert secondary impacts on the sediment distribution pattern. To evaluate past hydroclimatic changes, short sediment cores were retrieved from the continental shelfand upper slope of the south Caspian Sea and were treated for basic sedimentological properties and mineralogy. Tue results show that the sediments are composed of terrigenous, biogenic, and chemical components. The chemical component has a significant signature in the intemal structure of the sediment, which reflects degradation of organic material due to a succession of aerobic and anaerobic conditions. Aerobic conditions reflect the extreme climatic conditions that Jead to formation of well-oxygenated deep water in lowstands and extremely cold winters, when dense oxygenated water is allowed to touch the bottom sediments. The sediment distribution pattern demonstrates three distinctive areas in the southern continental margin with different organic matter and carbonate content. Pluvial inputs and wave hydrodynamics control the sediment properties and their distribution pattern in the upper shelf, while in deeper parts, the dynamics ofwater stratification and its temporal and Jong·term variations, relating to climate and water Jevel changes, detennine sediment composition. Overall, the sedimentary distribution pattem is a result of their sources in the catchment basin and the hydroclimate of the Caspian Sea.

    Description: This study was conducted to compare the effect of two anesthetizers Topped lavender essential oil (Lavandula angustifolia) and clove oil on some hematological and serum biochemical parameters in common carp (Cyprinus carpio) juveniles. Common carp juveniles exposed to three treatments including optimum concentration of Topped lavender essential oil (170 mg l^-1 ), clove oil (35 mg l^-1 ) and control and hematological, serum biochemical and stress parameters were determined at different times including 0, 3 and 24 h after anesthetizing. The results showed the effect of treatment (anesthetizing agent) on all hematological parameters, the effect of time on WBC, Hb, MCH and MCHC, the interaction effect of treatment and time on Hct and RBC and the effect of treatment, time and the interaction effect of them on all serum biochemical parameters were significant (p〈0.05). Over the studied period after anesthetizing, RBC didn’t show significant difference between Topped lavender and control (p〉0.05), but in clove oil at the start of anesthetizing time (0) was significantly higher than other sampling times (p〈0.05). WBC showed significant decrease compare to other treatments in all sampling times (p〈0.05). Over the studied period after anesthetizing, Hb decreased in the control group and increased in Topped lavender and clove oil treatments (p〈0.05), Hct also showed significant increase in the control group (p〈0.05) and didn’t significant difference in other treatments (p〉0.05). In all times, the lowest amount of glucose was observed in Topped lavender treatment; in Topped lavender and clove oil treatment, after increase in 3 h after anesthetizing, showed decrease in 24 h (p〈0.05). The amount of Cortisol didn’t have significant difference between the control and Clove oil groups (p〉0.05). In all the studied times, higher level of AST in the control, ALT in the control and clove oil, ALP in clove oil and the lower LDH in Topped lavender groups were observed (p〈0.05). Overall, although the effect of Topped lavender essential oil on determined parameters showed some difference with clove oil, but Topped lavender essential oil can introduce as native anesthetizing replacement agent for aquaculture.

    Description: Salted Kutum roe was prepared by soaking in brine to a traditional procedure. Proximate composition (moisture, protein, lipid, pH, ash and salt content), total volatile basic nitrogen (TVB-N), fatty acid profiles and microbiological characteristics of raw and salted roe of Caspian white fish (Rutilus frisii kutum) were determined. The results indicated that protein and moisture contents were significantly higher in raw roe compared to salted one (28.81 and 61.07% to 23.99 and 51.57%, respectively). Significant differences in ash and salt contents were obtained among different treatments. TVB-N in all samples was less than 25mg/100g. The gas chromatography (GC) analysis showed that the major saturated fatty, monounsaturated fatty acids and poly unsaturated fatty acids were 16:0, 18:1n-9, and 22:6n-3, respectively. Aerobic plate count (APC) and Total Coliform Count (TC) in all samples were significantly higher (p〈0.05) in raw roe (5.33 logCFU/g and 210 MPN/g) compared to salted roe (1.23 log CFU/g and 1.2 MPN/g). None of the samples contained Escherichia coli, Salmonella, Clostridium perfringens or yeast.

    Description: The aim of the present study was to detect polymorphism in Insulin like growth factor-I (IGF-I) gene of beluga (Huso huso) fish using PCR-SSCP technique and also investigation of its association with growth traits (condition factor, body length and weight). A total of 150 specimens of beluga were randomly selected and DNA was isolated from caudal fin using modified salting out method. Then two fragments of 171 and 362 bp from 5'-UTR and 3'-UTR regions of IGF-I gene were amplified, respectively. Genotyping of individuals by SSCP technique showed five banding patterns of A, B, C, D and E for 5'-UTR region with the frequencies of 29.2, 0.76, 16.92, 51.53 and 10% respectively in one year-old and three banding patterns of A, C and D with the frequency of 45, 10 and 45% for two year-old fish. Also three banding patterns (A, B and C) were seen for 3'-UTR region with the frequency of 62.3, 27.69 and 10.76% in one-year-old and 20, 60 and 20% in two year-old fish. The A banding pattern in 3'-UTR and D banding pattern in 5'-UTR sites were the most frequent pattern in the studied beluga population. The association analysis using SAS statistical software indicated no significant association between observed banding patterns and growth traits (body length, weight, and condition factor) in beluga. Considering the important role of IGF-I as a probable candidate gene affecting growth related traits, these marker sites should be studied more in larger sample sizes and also in other regions of the gene.

    Description: This study evaluated the effects of diets including different levels of oregano (Origanum vulgare L.( essential oil on growth indices and fillet quality of rainbow trout (Oncorhynchus mykiss) during refrigerated storage (4±1°C). For this purpose, rainbow trout with an average weight of 69.38±0.44 g were fed with diets containing 0, 250, 500 and 750 mg kg-1 oregano essential oil for 48 days. After the end of 48 days, growth parameters were measured and also some fishes of experimental groups were filleted and stored at refrigerator (4±1˚C) for 21 days due to quality investigation. Total psychrophilic counts, TBA and TVB-N analyses were done every 7 days (day 0, 7, 14 and 21). The results showed significant differences in some growth parameters including final weight, weight gain, weight gain percent and feed conversion ratio among experimental groups (p〈0.05).The results also showed lower amount of total psychrophilic counts and TBA in rainbow trout fillet from oregano groups than control group, during refrigerated storage(p〈0.05). As on day 21, the highest amount of PTC was obtained in control (14.39±0.12 log cfu/g) and the least amount of that was obtained in 250 mg kg-1 (12.38±0.09 log cfu/g).The highest amount of TBA was also observed in control (1.57±0.05 log cfu/g) and the least amount of that was observed in 750 mg kg-1 (1.20±0.08 log cfu/g) (p〈0.05). No significant differences were observed among essential oil treatments. Overally, it could be say using500 mg oregano essential oil can cause improvement of growth and rainbow trout fillet quality during refrigerated storage (4±1°C).

    Description: The aim of the current study was to evaluate the effect of dietary Lactococcus lactis subsp. lactis and chitin on blood and serum biochemical parameters and intestine bacteria of common carp. To do the experiment, 360 juvenile carp with mean initial weight of 12±1.5 g were randomly distributed in the fiberglass tanks designed based on different levels of chitin 0, 1 and 2% and probiotic 0 and 2% (1 ×107CFU/g) in diet and the experiment lasted for eight weeks. The experimental treatments were including control (treatment 1), probiotic 2% (treatment 2), chitin 1% (treatment 3), chitin 2% (treatment 4), probiotic 2% + chitin 1% (treatment 5) and probiotic 2% + chitin 1% (treatment 6). On the end of the experiment, blood parameters including red blood cell (RBC), Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), hemoglobin (Hb), hematocrit (HCT), white blood cell (WBC), lymphocyte, eosinophil and monocyte, serum biochemical parameters including total protein, albumin, glucose, cholesterol, triglyceride and intestinal bacterial colony were determined. The results showed that RBC, MCV, MCH, MCHC, Hb, HCT, thrombocyte, monocyte had no significant difference among treatments (p〉0.05), But, maximum level of WBC in treatments 5 and 3 (18.03±1.66, 16.86±1.49 103 mm3, respectively), lymphocyte in treatments 5 and 2 (70.40±4.58, 65.00±2.65, respectively) and eosinophil in treatments 3 and 6 (2.67±1.16, 1.67±0.58, respectively) were observed. Biochemical parameters showed no significant difference among experimental treatments and control, but, there were significant difference among the diets containing probiotic and chitin or/and a mixture of probiotic and chitin (p〈0.05). The intestinal bacterial colony in all treatments except treatment 6 was more than the control (p〈0.05). The maximum bacterial colony count was observed in treatment 4 (653.33±25.17 CFU/g). In conclusion, it seems the addition 2% probiotic, 1% chitin and a mixture of them can improve white blood cells and intestinal bacterial colony in common carp.
