The aim of this study was to investigate the effect of chitosan and cooking methods (pan-frying and microwave) on the rate of heterocyclic aromatic amine compounds formation in the fillet of Beluga sturgeon. The experiment was designed in 6 treatments, including T1 (control without chitosan), T2 (fried treatment without chitosan), T3 (sample containing 1% acid soluble chitosan), T4 (fried sample containing 1% acid-soluble chitosan), T5 (sample cooked in microwave without chitosan) and T6 (sample cooked in microwave containing 1% acid-soluble chitosan). The use of acid-soluble chitosan (1%) had a significant effect on moisture content, pH and weight changes during cooking (P<0.05). In the cooked fillet, the HAAs values including PhIP (-5.68-Nd), IQ (-1.16-Nd), MeIQ (-1.66-Nd), and MeIQx (0.7-6.47) were detected. The inhibition rate of chitosan for the heterocyclic compounds in cooked fillet was 57.44 to 63.98%. The results showed that acid-soluble chitosan had a significant effect on cooking indices and reduced production of the heterocyclic aromatic amine compounds on cooked huso fillets.

This experiment was carried out to evaluate the effect of Suspension on different levels of probiotic Bacillus (Aqua 1 and 2) on the water quality parameters, feed and growth performance and body biochemical compounds of Common carp (Cyprinus carpio) fry in a biofloc system. A total of 450 of fish (with mean initial body weight of 2.09±0.52 g) were divided into five experimental groups (3 replicates each) for 40 days. Experimental diets and biofloc were identical in all, except for the variation in probiotic levels. Two levels of probiotic bacillus and one control was designed which includes; A probiotic was used at 0 (control), Aqua 1: 1.5×108 (T1) and 3×108 (T2), Aqua 2: 1.5×108 (T3) and 3×108 (T4) Inoculation in the culture water. The end of experiment, Mean feed and growth parameters in all probiotic treatments had a significant increase compared to control treatment. The results showed that the highest and lowest final weight was related to T4 (9.31±1.52 g) and control (6.67±0.78 g). Body composition was measured so that the highest protein content and lowest lipid content were obtained in T1 treatment. Water quality analysis was carried out on days 6, 23 and 40. At the end of the experiment (day 40), the concentration of ammonia was not significantly different between the control and experimental treatments, while the concentration of nitrate was changed. Based on the results of this study, the probiotic Bacillus at 3×108 in T4 treatment had a positive effect on feed and growth indices of common carp in biofloc system but did not effect on ammonia.

This study was investigated organic (glucose, cholesterol, total protein and albumin) and ionic (calcium, phosphorus, magnesium, sodium and potassium) composition of the ovarian fluid and blood serum of 6 males (mean weight 424.37±37.84 g and mean length 36.19±1.32 cm) and 9 females (mean weight 1225.87±89.47 g and mean length 50.5±0.6 cm) of snow trout Schizothorax zarudnyi broods. Also, the sperm motility duration in combination of seminal fluid with 0, 15, 30, 45, 60, 75, 90 and 100% of ovarian fluid was measured. The ovarian fluid solution alone (100%) did not increase sperm motility. The shortest duration of sperm motility (44.67±0.56 s) with pure water and the highest duration of motility (67±5.37 s) was obtained by combining 55% water and 45% ovarian fluid that showed significant different with groups contain 0, 15, 30 and 60% of the ovarian fluid (P<0.05). There were differences in the composition of ovarian fluid, semen and blood serum. With the exception of magnesium, all other parameters of the female blood and ovarian fluid and all male blood and semen parameters were significantly different. Inaddition, there was a significant difference in the glucose, and total protein between blood serum of males and females. Comparison composition of the ovarian fluid, seminal fluid and blood serum of female and male broods showed the highest glucose and total protein in blood male serum, highest cholesterol and sodium in female and male blood serum, highest calcium in female blood serum, lowest magnesium and highest potassium in seminal fluid. The results showed increasing of the sperm motility duration with ovarian fluid at median concentrations in the activation medium. Also, the results revealed a possible important female contribution to sperm motility enhancement during the fertilization process in S. zarudnyi.

This study investigated effect of the partial and total replacement of astaxanthin with carrot powder (0, 25, 50, 75 and 100%) on the carotenoid content of the skin, fillet and blood of rainbow trout (Oncorhynchus mykiss). Therefore, a completely randomized design with 5 treatments and one control group, each with 3 replications, was designed. A total of 300 fish with an average initial weight of 50.00±30 g were divided into 18 experimental fiberglass ponds. The experiment period was 60 days. The results showed that addition of the carrot powder to diet had a significant effect on the carotenoid level of the skin, fillets and blood of fish, resulting in red color. Carotenoid concentration of the skin and fillet increased significantly by adding carrot powder to diet (P<0.05). Addition of 50 and 75% of the carrot powder as a natural pigment resulted in the highest amount of the carotenoid storage in the tissue and skin (0.40413±0.029 and 0.0240-0.001 mg/kg) and had a significant difference with other treatments (P<0.05). The results showed that Carrot's carotinoids were significantly higher in treatments of 50 and 75% than others (P<0.05) and the lowest level (0.0269±0.30 mg/kg) was observed in the control group.

Kefir grains are a natural source of probiotic strains belonging to the family of lactic acid bacteria. This study aimed to isolate and identify the strains of lactic acid bacteria in kefir. In addition, to evaluating their probiotic properties, the effect of their oral administration on some hematological andgrowth parameters in rainbow trout was also investigated. The findings indicated the isolation and identification of Lactobacillus farraginis and Enterococcus durans strains, which showed important characteristics of probiotic strains, such as resistance to acidic conditions, gastric juice and bile salts, as well as good hydrophobicity and antagonistic activity against some pathogenic strains. A total of 480 fish with an average weight of 41.9±4.2 g in a completely random design, divided into 8 groups of 20 specimens in three replications. Control treatment (basal diet), L1and E1 treatments, respectively receiving (basal diet + L. faraginis) and (basal diet + E. durans) dose of 107 Cfu/g; treatments L2 and E2 receiving dose of 108 (CFU/g); the combined treatments (L1+E1 (5×106 and (L2+E2) 5×107 (CFU/g) and Bactocelltretment as a positive control (basal diet + Pediococcus acidilactici lactis) 1010 (Cfu/g). Sampling of treatments after 45 days from the beginning of the experimentwas done. According to the findings, that total red blood cells, hematocrit, hemoglobin level, mean hemoglobin concentration and growth parameters including BWI, SGR and CF were significantly (P<0.05) increased in L2+E2, Bactocell, L2, and E2 treatments, Whereas, the decrease in FCR in these groups was evident compared to control on. The strains appear to be suitable probiotic candidates for adding to the rainbow trout diet, but this requires further in vitro and in vitro studies.

Spirulina platensis is useful because of having special amino acids balance for human and animal nutrition. This study was conducted to investigate the possibility of cultivating S. platensis by enriching the Persian Gulf water by nitrogen and carbon sources in a completely randomized design for 21 days. The experimental treatments were (1) seawater (control), (2) seawater enriched with urea, (3) seawater enriched with sodium bicarbonate, and (4) seawater enriched with sodium bicarbonate and urea. The results showed that there was a significant effect on biomass production between treatments 1 with 3, and 1 with 4 (P<0.05). An increase in biomass of the treatment four was maximized due to nitrogen and carbon supply, in comparison to others. According to the results, it can be concluded that the enrichment of the Persian Gulf water and its geographical location, the sea shores can be used for cultivation of S. platensis.

A 6-week experiment was conducted to investigate the effects of dietary supplementation of red macroalga, Gracilaria pygmaea on proximate analysis, apparent digestibility and digestive enzymes activities of Asian sea bass, Lates calcarifer, with an initial mean weight of 28±5.9 g using a completely random design. The experimental diets were prepared using a fishmeal based positive control diet and a fishmeal-soy protein negative control diet supplemented with 3, 6 and 9% of red macro algae. The results indicated that the special growth rate was significantly higher for the 6% G. pygmea inclusion (P<0.05). At the end of the trial, the crude protein, ash and dry matter of fish carcass were not significantly different between the treatments (P>0.05), except for the fish fed with the 3% inclusion diet that exhibited significantly higher lipid level compared to the others (P<0.05). The results of the apparent digestibility of protein, fat and dry matter did not show significant differences (P>0.05), although these values were slightly improved in 6% inclusion treatment. The pepsin activity was decreased by about 1.46-fold and 1.26-fold in fish fed with the 9% diet when compared with those fed with the 3 and 6%, respectively (P<0.05). Activities of amylase and lipase were significantly lower in 9% treatment compared to 3 and 6% treatments (P<0.05). Present findings show the potential of G. pygmaea powder as a dietary supplement up to 6% inclusion in the diet to improve growth performance, carcass proximate composition, apparent digestibility and most of the digestive enzymes activities of the carnivorous Asian sea bass.

For seasonal changes investigation of filleting yield and nutritional values of orange-spotted grouper fish (Epinephelus coioides), 80 kg fish was caught from coastal waters of Hormozgan Province (Bandar Abbas region). Fish are chilled and transported to laboratory. Then, after washing, fish were filleted by hand. Fillet yield, proximate composition, total energy and fatty acid profile were determined. The result showed that the average of the fillet yield was 41.84%. The highest and lowest was recorded, respectively, at winter (43%) and autumn (39%). Grouper fish fillet was content protein (19%), lipid (2.8%). Grouper fillet was characterized by the highest content of polyunsaturated fatty acids (PUFA) than other classes of fatty acids in all seasons. The must of Docosahexaenoic acid content at autumn (27.61±5.17 mg/gr), eiosapentaenoic acid at spring (7.17±0.31 mg/gr) and arashidonic acid at autumn (8.9±1.6 mg/gr) were recorded. Sum of contents of EPA+DHA, an indicator of nutritive value of fish, had the highest value in autumn (34.45 mg/g FAME). These results suggested that grouper fish fillet at autumn, although having a lower yield had the maximum nutritive value regarding EPA+DHA for healthy life. In additional fish fillet at autumn contains suitable protein and lipid. In conclusion fish fillet at autumn can be suggested for production and supply to market.

The present study was conducted to investigate the effect of Padina astraulis pretreatment on the gill and liver tissues of common carp (Cyprinus carpio) exposed to ZnO nanoparticles. A totalof 250 fish, weighing 20±2.4 g, were distributed in to 5 treatments, including no algae (treatment 1, control), diet containing 0.5% algae (treatment 2), 1% algae (treatment 3) and 2% algae (treatment 4), each treatment in triplicates and fed 3% body weight for 42 days. Upon finishing feeding trial, fish were exposed to 50% lethal concentration of zinc oxide nanoparticles for 14 days. The results of gill histopathology in nano-zinc-only treatments showed apical hyperplasia, basal hyperplasia, shortening of the epithelial gill glands, bending of the secondary lamella cells, and intense lamellar adhesion and these histopathologic alternations significantly decreased in those treatments with higher concentration of padina algae. Nano-zinc and algae significantly decreased with the elevation concentration of padina algae. In addition, nano-zinc treatments were caused tissue damage such as atrophy, biliary edema, sinusoidal inflammation, hemorrhage, hemorrhage, and flooding, and cloudy deformity in the liver, however, these effects were observed in nano and algae combination treatments, but their severity decreased with increasing the concentrations of padina algae. It can be concluded that application of Padina algae can play an effective role in reducing tissue lesions (liver and gill) in exposure to zinc nanoparticles.

Due to the development of intensive aquaculture systems that is associated with increased environmental impacts and the use of chlorine compounds due to their availability, efficiency and cost, the present study aimed to investigate the effect of chlorination on the physicochemical parameters of aquaculture effluent including nitrate, phosphate, TDS, TOC, ORP, BOD, COD, pH, EC and MPN. For this study, 200 liters of rainbow trout farms’ effluent were collected from the lowest outlet of Karaj Mahi-sara farm in Bilqan, Karaj and transferred to Sheikh Bahai Laboratory, Islamic Azad University Science and Research Branch. The effluent was designed in a control group and four treatments of chlorine with different levels, including 30, 20, 10, 40 mg/L liquid hypochlorite (3 times in 5-liter containers for 24 hours with shaker). After this period, 100 ml samples were taken from each container and qualitative indices were analyzed. The results showed that with increasing chlorine, bacterial BOD, COD, TDS, TOC, EC, nitrate and MPN parameters decreased tha highest difference (P<0.05) third treatment with control one in TDS and with 4th treatments with other parameters indicated. ORP increased with increasing chlorine content, but increasing chlorine level did not have significant effect on pH and phosphate indices. The results showed that with increasing chlorine content, water and wastewater quality and biological indices improved to environmental standards. Based on the results, the fourth treatment with 40 mg / L had the best performance in improving the physicochemical parameters of the wastewater and the BOD, COD and TOC indices showed the highest response in this study.

Bread is the main food of people in many countries of the world. Due to the fact that wheat protein is poor in amino acids, especially lysine, as well as unsaturated fatty acids (omega-3 and omega-6). Amino acids and fatty acids are essential for biological activities and their deficiency causes many physiological disorders in humans. Fish protein concentrate is a rich source of protein, especially amino acids and fatty acids required for body, which is suitable to meet these needs. In this study, the effect of using different levels of Silver Carp Protein Concentrate (SCPC), (control treatment), 2, 3 and 4% (treatments A, B, C and D, respectively) on chemical indices and physicochemical nature of the produced breads were investigated using a completely randomized design. Based on the results, in all treatments, the amount of protein, fat, moisture, WHC, pH increased and there was a significant difference (p < /em><0.05). The results showed that essential amino acids especially lysine and methionine as well as fatty acids (especially EPA and DHA) in treatment D increased compared to the control and there was a significant difference (p < /em><0.05). With increasing the share of SCPC, the amount of nutrient indicators tested increased significantly and the data were significant. Treatment D with high levels of these nutrients is recommended for enriching bread and other products such as pasta, biscuits, etc.
