Common carp (mean weight 50 g) was fed in six treatments with 0.25 and 0.50 mg/g iron oxide nanoparticles and 10 8 CFU/g commercial Lactobacillus probiotic either together or separately for 56 days. After the rearing period, blood biochemical parameters including total plasma protein, albumin, globulin, creatinine, triglyceride and cholesterol and ALP, ALT, AST and LDH enzymes were measured. Total protein and globulin levels showed a significant increase in probiotic alone and probiotic plus 0.50 mg iron nanoparticles treatments ( p ≤ 0.05). Creatinine, albumin, liver enzymes, serum lipids did not show any significant differences between treatments ( p ≥ 0.05), but the values of these parameters showed no negative effects in different treatments. Based on the findings of this study, it can be concluded that using iron nanoparticles and Lactobacillus probiotic can improve some of the biochemical factors in carp.

The purpose of present study was to evaluate using grape pomace as a main feed ingredient on growth performance, body chemical composition, survival rate, and morphological indices of the carp (Cyprinus carpio). 200 fish with an average weight of 7 ± 0.4 g were randomly distributed in four tanks for total of 56 days. The fish were fed with a diet containing 5%, 10%, and 15% grape pomace in different feeding groups designated as G1, G2, and G3. The average daily weight gain (g), weights gain (g), and specific growth rate (%) were significantly higher (p &lt; .05) in G3 as compared to G1 and G2 groups. The lowest feed conversion ratio was recorded in G3 group. The morphological indices, condition factors, viscerosomatic index, and hepatosomatic index were significantly higher in G3 group as compared to other treatments. The protein, fat, moisture, and ash contents in the C. carpio fillets were significantly influenced by feeding rate. The results showed that grape pomace had a positive effect on growth, survival, and nutritional indices in the carp fish. According to the obtained results, grape pomace (150 g/kg food) can be considered as the diet component for the carp fish.

Common carp fry with an average weight of 20 ± 0.2 g were fed using the diet containing B. vulgaris leaves with different concentrations. Fry of Cyprinus carpio were equally distributed in four feeding groups having three replicates each. The study was conducted indoors, in FRP tanks, and aeration was provided to individual rearing units, and it was a flow‐through system. The basal diet was replaced at 0.5%, 1%, and 2% with B. vulgaris powder. The basal diet without B. vulgaris powder (0%) served as control (T1). Significantly higher feed conversion ratio, protein efficiency ratio, and fat and protein indices were recorded in fish fed with B. vulgaris powder in treatments. Different feeding groups showed greater acceptability of B. vulgaris powder mixed diet without any adverse behavioral response. The protein and fat average percentages were 43.32 and 10.79 g, when fish reached commercial weight (48.02, 11.85 g) after 56 days for treatment 2%. After fish feeding with the B. vulgaris, for treatment 2% lower moisture than the control was recorded. The carp fish diet containing 1% B. vulgaris leaf powder caused a significant decrease in the fish fat content. It can be concluded that the diet containing 2% B. vulgaris leaf powder in the common carp led to better growth performance. The presence of B. vulgaris leaves in the fish diet increased the fillet protein and ash content.

The experiment was carried out in four treatments (each with 3 replicates), including T1 = control with non-synbiotic diet, T2 = 0.5 g/kg synbiotic diet, T3 = 1 g/kg synbiotic diet, and T4 = 1.5 g/kg synbiotic diet. In total 300 fish with an average weight of 10 ± 1 g were distributed in 12 tanks (25 animals per 300 l) and were fed experimental diets over a period of 60 days. The results showed that synbiotic could significantly enhance growth parameters (weight gain, length gain, specific growth rate, percentage weight gain) (P < 0.05), but did not exhibit any effect on survival rate (P > 0.05) compared with the control. An assay of the digestive enzyme activities demonstrated that the trypsin and chymotrypsin activities of synbiotic groups were considerably increased than those in the control (P < 0.05), but there was no significant difference in the levels of α-amylase, lipase, or alkaline phosphatase (P > 0.05). This study indicated that different levels of synbiotic have the capability to enhance probiotic substitution, to improve digestive enzyme activity which leads to digestive system efficiency, and finally to increase growth. It seems that the studied synbiotic could serve as a good diet supplement for common carp cultures.

The proximate composition of treated Chirocentrus nudus (protein, fat, ash and energetic value) for 8% salt and 18 h brining was 61.2%, 15.2%, 23.2% and 381.60 kcal/100g respectively. Fat and ash contents in brined fillets of Nemipterus japonicus and Saurida tumbil were found lower and more than C. nudus respectively. As for the proximate composition of C. nudus, it is clearly observed that all the studied parameters are significantly different in fresh and treated samples. Variations appeared in nutrients was due to the interaction of the salting treatment. It is concluded that fish treated C. nudus was best option.

The counts of Bacillus bacteria in the digestive tract in all treatments were significantly (P b 0.05) higher than in controls (no Bacillus bacteria were detected in any controls), although total bacterial counts were not significantly different among treatments and controls. Colonization rates of shrimp digestive tracts by Bacillus bacteria were very low in all treatments in earthen ponds. In most treatments, the specific activities of amylase, total protease, and lipase were significantly higher (P b 0.05) in shrimp to which probiotic had been administered, and shrimp that had received probiotic exhibited significant (P b 0.05) increases in both survival (11-17% higher) and wet weight (8-22% higher) as compared to controls. Shrimp fed probiotic-enriched Artemia had significantly (P b 0.05) higher Bacillus counts than did shrimp administered probiotic in the water, but growth and survival were not significantly different between the two modes of administration. Where probiotic was administered during both the hatchery stages (Nauplius 1-2 through PL 30) and the farming stages, the feed conversion ratio, specific growth rate, and final production were slightly, but significantly (P b 0.05), higher in shrimp receiving the probiotic than in control shrimp which had received no probiotic. Because these improvements in growth parameters in postlarval shrimp were significant only in shrimp
