This 70-day experiment examined the effect of protease added to the commercial feed of Sterlet (Acipenser ruthenus) at concentrations of 0 (control group), 75 mg (T1 treatment), 150 mg (T2 treatment) and 300 mg (T3 treatment) per kg of diet on growth parameters and carcass composition. a number of 180 juvenile Sterlet with an average body weight of 6.02±0.34 g was randomly divided into 12 fibreglass tanks with stocking density  of 15 fish per each tank. At the end of the experiment, growth parameters indicated a significant difference between experimental treatments compared to the control group (p<0.05). The highest final weight (66.45 ± 0.33 g), weight gain (59.44 ± 0.52 g), specific growth rate (1.39 ± 0.02 %/day), protein efficiency ratio (2.43±0.11) and the lowest food conversion ratio (0.84±0.04) were measured in T3 treatment. However, the highest amount of condition factor (2.34±0.08%) was recorded in the T2 treatment (p<0.05). The carcass composition showed a significant increase between all the investigated indices in the experimental treatments compared to the control group (p<0.05). The highest amounts of dry matter (26.54±0.06%) and crude protein (15.27±0.02%) were measured in the T3 treatment. The highest amount of crude fat (8.07±0.05%) was in the T1 treatment. The highest amount of ash (2.27±0.02%) was observed in the T2 treatment. Based on the obtained results, it can be concluded that protease in concentrations of 75 to 300 mg per kg positively affected the growth and chemical composition of carcass A. ruthenus.

Aquaculture development is challenged with limitation and high costs of supplying protein diets, so searching for alternative protein sources in fish diets is inevitable (Tacon, 2020). Insect meals are considered as a promising substitution protein ingredients last decades (Alfiko et al., 2022). Among candidates’ insect meals, Silkworm is well-balanced in protein as well as lipid and can be served as feedstuff (Mahanta et al., 2023). A study conducted to investigate if low level of silk worm pupa inclusion in fingerling Beluga sturgeon (Huso huso) diet could provide a protein source replacement accompanying with high benefit for the species.

Fingerling Beluga sturgeons (5±0.2 g, mean±SE) fed with experimental diets for a period of 8 weeks. Four experimental diets includes: no (SWP) inclusion as a control treatment (T0), 5, 10 and 15 percent (SWP) substitution referred as (T5, T10 and T15) treatments. At the end of the experiment, Weight Gain (WG), Specific Growth Rate (SGR) and Feed Conversion Ratio (FCR) calculated to assess the diets quality on fish production. Hepatic enzyme (ALP, AST, and ALT) and serum biochemical (IgM, total protein and lysozyme) analyzed for revealing the health status of fish.

(SWP) treatments, in particular (T15) had a significant increase in (WG) compared to the control group (p<0.05). (SGR) as well as (CF) in (SWP) treatments showed no significant differences compare to the (T0) (p<0.05). (FCR) was significantly improved among (SWP) treatments, although the difference was not significant (p<0.05). Serum lysozyme, Serum immunoglobin and total protein in (T10) and (T15) were significantly increased compared to the control group, (T0) (p<0.05).

Our findings indicate the protein level adjusts and fixes with the (SWP) was efficiently enough to be replaced with fish meal in fingerling Beluga sturgeon (H. huso). The results of (SGR) as well as (CF) suggest that the replacement level could be changes to more to get a differently improved result. Hepatic enzymes showed that (SWP) did not affect impairment in digestive tract.  What’s more, blood biochemical analysis showed that (SWP) can have immunomodulatory effects on fingerling Beluga sturgeons (Zhou et al., 2022)

In fish farming industry, the use of nutritional supplements, including enzymes, is recognized as a vital strategy to enhance nutritional performance and growth. This study aimed to evaluate the effect of enzymatic extract from pyloric appendages on the growth performance and body composition of rainbow trout fry. Four dietary treatments were prepared, including a control diet (A: without enzyme) and three diets containing different levels of enzyme extract (B: 0.5 g/kg, C: 1 g/kg, and D: 2 g/kg of feed) with uniform protein and energy content. The results indicated that diets D and C exhibited the best growth performance compared to other experimental diets. These diets significantly outperformed others in terms of body weight increase and daily growth rate. Moreover, they showed the best feed conversion ratio, indicating efficient feed utilization. Additionally, diet D showed the highest specific growth rate and condition factor, while diet C exhibited the highest survival rate, although these differences were not statistically significant. The ash content in diet D was also significantly higher compared to other diets. Diets D and C significantly increased protein efficiency ratio and lipid efficiency ratio. The findings suggest that the inclusion of 2 g/kg enzymatic extract from pyloric appendages can improve the growth and nutritional performance of rainbow trout fry.

Studies on nutrient utilization and growth performance of Beluga (Huso huso) raised on five feeding schedules (treatment 1 continuously fed plant protein diet, treatment 2 continuously fed fish meal diet, treatment 3 alternate feeding of a 1-day plant protein diet; followed by a 1-day fish meal diet, treatment 4 plant protein diet in the morning fallowed by fish meal diet in the afternoon and treatment 5 fish meal diet in the morning followed by plant protein diet in the afternoon) in 3 replication (20 fish in each repetition) under laboratory conditions showed that continuous feeding with Fish meal diet (treatment 2) resulted in maximum growth, which was not significantly different from treatments 4 and 5 (p<0.05). While feeding with plant protein diet (treatment 1) and feeding every other day (treatment 3) led to a decrease in fish growth performance (p<0.05). In terms of protein digestibility, the best treatments were 2, 4 and 5, which did not show any significant difference with other treatments (p<0.05). The highest amount of muscle arginine belonged to treatments 2, 4 and 5, which was significantly higher than muscle arginine of fish fed with treatments 1 and 3 (p<0.05). Also, the highest amount of glycine was observed in treatment 5, which was not significantly different from other treatments except treatment 1. No significant difference was observed in the amounts of other muscle amino acids of the experimental treatments (p<0.05). The obtained results showed that the alternating change of the dietary protein source during one day (morning and evening and vice versa) does not have any negative effect on the growth performance and feed efficiency, and in most of the nutritional factors, it is equal to the treatment fed with fish meal.

Using herbal extracts as nutritional additives in aquaculture industry increases the resistance of fish to infectious agents while also providing a substitute for traditional antibiotics, enhancing the immune system, and promoting the growth of fish. The present experiments were designed to investigate the effects of a diet containing hydroalcoholic extract of savory (Satureja hortensis) on the growth performance, hematological parameters, and histopathology of the intestine in rainbow trout (Oncorhynchus mykiss) fry. For this purpose, 240 rainbow trout fry with an average weight of 2.02 ± 0.02 grs were randomly distributed into 4 experimental groups with three replicates and fed diets containing concentrations of 0 (control), 0.1%, 0.5%, and 1% hydroalcoholic extract of savory for 6 weeks. The results showed that growth performance indices including final weight, body weight gain, and specific growth rate significantly increased in the group fed with a diet containing 1% extract compared to the control group. Additionally, the number of white and red blood cells, and hematocrit levels increased in the groups fed with savory extract (P<0.05). The use of hydroalcoholic extract of savory in the diet of rainbow trout fry had no negative effect on the distal intestine tissue of the fish in all groups. Overall, the results indicated that feeding with 1% hydroalcoholic extract of savory in the diet could improve the health and better growth of rainbow trout fry.

The effect of dietary administration of combination of hydro-alcoholic extracts of turmeric (Curcuma longa L.) and thyme (Zataria multiflora Boiss) on growth performance, nutritional parameters, digestive enzymes activity and antioxidant properties of rainbow trout (Oncorhynchus mykiss) was investigated. Three experimental diets including basal diet (control group) and diets containing 0.5% and 1.5% of combination of turmeric and thyme (ratio of 1:2) extracts were prepared. A total of 234 juveniles of rainbow trout were randomly divided into three experimental groups in triplicates (providing 26 fish per replicate) and reared for eight weeks. Feeding diets contained 0.5 % of the extract increased the feed efficiency ratio and condition factor of rainbow trout compared to the control group (P<0.05). Supplementing 1.5 % plant extract increased the Average Daily Growth (ADG) of the fish in comparison to control group (P<0.05). Both dietary levels of the extracts increased protein productive value and lipid productive value of fish compared to control group (P<0.05). Viscerosomatic and hepatosomatic index were affected by both dietary extract levels compared to control group (P<0.05). Dietary plant extract inclusion significantly increased the activity of amylase and lipase (P<0.05). Similarly, the activity of superoxide dismutase and glutathione peroxidase significantly increased in the liver tissue of rainbow trout following feeding on diets containing the extracts, while malondialdehyde content of the tissue decreased in comparison to the control group (P<0.05). Therefore, considering the promising effects of dietary supplementation of turmeric and thyme extracts, inclusion of 0.5% of the extracts in rainbow trout feed is recommended.

Oak acorn is widely used as animal feed due to its low price. Oak acorns (Quercus brantii) were processed by de-hulling, drying and milling. In acorn flour, the total phenolic compounds, non-tannin phenols and condensed tannins were 14.71, 0.35 and 6.60 g/100g on the basis of dry matter respectively. Five isonitrogenous and isoenergetic diets with different levels of acorn at 0 (control), 25, 50, 75 and 100 g/kg, were prepared. A total of 435 fish (average weight 0.3 g) were randomly distributed in 15 tanks with three replicates and fed for 10 weeks. Polynomial orthogonal contrast analysis revealed that there were no significant differences in terms of feed intake, feed conversion ratio, protein retention, carcass ash and survival rate between treatments (p>0.05). Dietary intake of acorn significantly affected the weight after four weeks, final weight after 10 weeks, total length, head depth, specific growth rate, condition factor, protein efficiency ratio, lipid retention and carcass lipid and moisture contents, which represented linear order polynomial (LOP) models, but crude protein content of carcass displayed a cubic order polynomial (COP) model, using optimal acorn flour levels of 25.00 – 64.28 g/kg. Acorn flour improved the protein level of carcass, but deteriorated the growth performance and carcass lipid and moisture levels. Therefore, even if the amount of de-hulled acorn flour in the diet is low (2.5 % of diet), it is not allowed to use it without further processing.

In this study, the effects of dietary extruded oak acorn flour on growth performance and carcass composition of common carp were studied. Four diets were investigated in a completely randomized design included 1- extruded wheat flour (17%), 2- non-extruded wheat flour (5%) and extruded wheat flour (12%), 3- non-extruded acorn flour (5%) and extruded wheat flour (12%), and 4- extruded acorn flour (5%) and extruded wheat flour (12%). The culture was started in round tanks with a volume of 250 liters and a density of 15 fish in each tank with an initial weight of 5.4 g in three replicates. After 4 weeks, no significant difference was observed in the weight and total length of fish, but after 8 weeks, the highest weight and total length were observed in the fish fed diet 4. Extrusion of acorn flour had a significant positive effect on the weight and total length of fish, but extrusion of wheat flour did not have such an effect. Diets had no significant effect on the condition factor, specific growth rate, feed intake, feed conversion ratio, protein efficiency ratio, lipid efficiency ratio, protein retention, carcass moisture content and survival rate. Extrusion of wheat flour and acorn flour had significant positive effects on lipid retention and these effects were much greater when the extruded acorn flour was consumed. The levels of carcass protein and ash were significantly reduced by feeding on non-extruded acorn flour. Consumption of non-extruded wheat flour or acorn flour caused a significant reduction in carcass lipid and this reduction was more severe when using non-extruded acorn flour. Overall after peeling the oak acorn, its flour can be used instead of wheat flour at the level of 5% of the extruded diet for common carp.

The present study was performed to investigate the effect of replacing fish meal with sunflower meal in the diet and its effect on the growth performance and biochemical compositions of Rutilus frisii fingerlings. For this purpose, 240 specimens with an average weight of 1.14±0.8 g and an average total length of 5.03±0.3 cm in 12 tubs with a density of 20 in each and in four different treatments of 0 (control), 25, 50, and 75% sunflower meal with food ration formulated with the same percentage of protein, fat and energy levels were tested for eight weeks. In the parameters of food conversion factor, protein efficiency rate, growth factor, weight gain, length increase, average daily growth, survival percentage, final length, initial and final weight, no significant differences were observed (P>0.05), but in terms of mean status coefficient, a significant difference was observed (P<0.05). Also, the analysis of fish carcass analysis parameters showed that there was no significant difference between the treatments in terms of carcass moisture percentage (P>0.05), but in terms of ash percentage, protein percentage and carcass fat percentage, there was a significant difference was observed (P<0.05). The results showed that different levels of replacing sunflower meal with fish meal have no negative effect on the growth performance of R. Frisii. Therefore, to reduce the cost of feed production and economic efficiency of the studied fish breeding, up to 25% of sunflower meal can be replaced with fish meal in the diet composition.

It is very important and necessary to choose the appropriate cold water fish species and check their growth performance in cage fish farming in the Caspian Sea. The results showed that the rainbow trout in Kiashahr region reached an average of 98.3±19.8 to 1149.8±203.5 grams in a period of 4.5 months. Also, although the breeding of salmon from the initial weight of about 100 grams was suitable, but considering the temperature limits for this fish in the Caspian Sea, the introduction of higher weights can reduce the length of the breeding period. Caspian Sea salmon reached in Jaffroud region from the average weight of 120.14±1.98 to 632.5±82.08 grams in a period of 4.5 months from January to May, and in Anzali free zone from 212.7 ± 15.28 to 508.81 ± 76.54 grams in a period of 2 months from January to March in floating cages, which shows the favorable growth of this fish in this region.

Biofloc system is a new technology that used in intensive and semi intensive aquaculture systems. The main advantage of this system is reducing the water use, along with increasing the intensity of production based on heterotrophic bacteria than autotrophic bacteria. The fish were divided into 4 groups in 3 replicates. The first group (A) was reared in normal culture situation as a control. In subsequent treatments, juvenile were rearing in a biofloc system containing various carbon sources, including: maize flour (B), Wheat flour (C) and barley flour (D) as different treatments. One hundred and twoenty fingerlings of common carp with initial average body weight of 15.18±2.07g introduced into the experimental treatments and cultured for 45 days. At the end of the experiment, water quality, growth preformance, and metabolic nitrogen excretion rates compared among treatments. Based on the results, water quality improved among all biofloc treatments compared to the control group (p<0.05). Growth indices significantly improved in all biofloc treatments (p<0.05). The highest growth rate and the lowest feed conversion ratio were recorded in the biofloc system containing barley flour (p<0.05). Ammonia and urea excretion in biofloc treatments were significantly higher than the control group (p<0.05). The highest ammonia and urea excretion rates were recorded in the biofloc treatment containing barley flour (p<0.05). Therefore, it was concluded that the use of barley flour as a carbon source in the biofloc system can be used for rearing of common carp. The use of this carbon source, in addition to improving of water quality, is effective in promoting the growth of common carp in the biofloc system..

In this study, the effect of Ethylenediaminetetraacetic acid (EDTA) was evaluated on growth performance and body composition in beluga (Huso huso) juveniles. For this purpose, a total of 225 beluga juveniles with initial weight 38.47 ± 0.58 gr (Mean ±   Standard Division) were fed with five treatments with three replications including 0 g/kg EDTA (Control, C), 5 g/kg EDTA (EDTA 5), 10 g/kg EDTA (EDTA 10), 15 g/kg EDTA (EDTA 15), and 20 g/kg EDTA (EDTA 20) for 8 weeks. At the end of the feeding trial, growth performance and body composition were investigated. The results showed that EDTA different levels have a significant effect on final weight, weight gain, and specific growth rate (p < 0.05).  The highest final weight, weight gain, and specific growth rate were observed in EDTA10 and EDTA15 treatments. The lowest final weight, weight gain, and specific growth rate obtained in the control group. The results of body composition analysis at the end of the feeding trial showed that no significant difference was observed in protein, ash, moisture, lipid, and dray mater between treatments (p > 0.05). The present study showed that feeding fish with the 15 gr/ kg diet EDTA improved growth and health.

The aim of the present study is to investigate the growth performance and sexual maturation process of female rainbow trout reared in a cage in the Caspian Sea (Mazandaran- Nowshahr). Rainbow trout with an average weight of 122± 5 g were stocked into a cage located in Caspian Sea. Fish were fed daily and random sampling was done monthly (January 2015) to May 2016. Weight and length of thirty fish were measured; their gonad and liver were weighted; total length, total weight, liver and gonad weight, condition factor, GSI and HSI and oocyte diameter were calculated; their blood samples were collected and the levels of 17 beta estradiol, testosterone, progesterone and the vitellogenin were measured; also gonad tissue samples were prepared and examined using a light microscope. The results showed optimal somatic and gonadal growth of fish caged in the Caspian Sea. Sex hormones and vitellogenin levels increased significantly (P<0.01) during the study period. The levels of 17 beta estradiol, testosterone and progesterone in January were 0.56± 0.05 ngml-1, 0.50± 0.05 ngml-1and 0.14± 0.01 ngml-1 respectively and reach to 1.63± 0.13 ngml-1, 0.80± 0.01 ngml-1 and 0.28± 0.03 ngml-1 in May, respectively. Vitellogenin levels increased from 382.40± 55.26 ngml-1 in January to 651.40± 86.34 ngml-1 in May. The gonads developed to stage 4 and the oocyte diameter increased significantly (P<0.01) during the study period. The findings of present study show that female rainbow trout are able to have appropriate somatic growth in the brackish water of the Caspian Sea like fresh water, and the natural process of sexual maturation won’t be disturbed.

This study aimed to investigate the effects of different temperatures (20, 27 and 33 °C) and two feeding rates (2.5 % biomass per day and satiation) on growth performance, body composition, hematology and blood biochemistry of Asian sea bass (Lates calcarifer). For this purpose, 8 fish with an average initial weight of 99.55 ± 0.24 g were randomly transported to 200 liters tanks (6 treatments with three replicates) and fish feeding was done using a commercial feed for 6 weeks. At the end of the experiment, the growth performance, blood indices and chemical composition of fish carcasses were measured. The results of this study showed that the feeding rate of biomass (2.5%) and satitation had no significant effects on growth performance and nutrition of this fish (P<0.05). However, different levels of temperature showed a significant effect on these indices (P <0.05). The average final weight of fish grown at 33 °C and fed at the biomass level was higher than other treatments, although this difference was not significantly different from that of the stored group at 27 °C. Among the hematology parameters, the number of red blood cells showed significant changes among treatments (P<0.05). Plasma biochemical parameters such as triglyceride, glucose and cholesterol level were significantly affected by water temperature and feeding rates (P <0.05). The activity of liver enzymes in plasma was not significantly different in different treatments (P <0.05). The protein and lipid content of fish carcasses increased with increasing temperature so that the group stored at 33 °C had the highest protein and lipid content (P <0.05). In general, the results of this study showed that temperatures above 27 °C are more optimal for this species and the feed rates of biomass and satiation have no significant effect on the growth and health performance of this fish in this temperature range.

The use of antibiotics in the diet of farmed aquatic organisms is done to reduce infectious diseases or enhance growth function. in recent years, the preventive use of antibiotics has been criticized, which has ultimately led to a ban on the production and breeding of farmed organisms by many countries. given the current limitations on antibiotic use, there is a fundamental need to evaluate options. organic acids or their salts, a potential alternative to preventing the overuse and promotion of antibiotics as well as dietary supplements and antimicrobials, have recently been considered by many researchers and breeders. this study emphasizes the effects of organic acids on growth, use as nutrients, availability of minerals, improvement of intestinal flora and disease resistance in marine fish.many studies have reported that some organic acids can significantly increase the growth performance and health of fish, and these results, depending on the aquatic species, the type and concentration of organic acids and the conditions of the farming environment use depends.

This study was carried with aim to investigate the restriction of feed, compensatory growth and the effect of probiotic (Bacilact) on growth performance, food productivity, survival and carcass composition of rainbow trout. Experiment was performed using a completely randomized design with three treatments consist of without hungry and basilicate treatment, feed restriction treatments with and without Bacilact during 2 weeks. The treatments were fed in re-feeding phase, to satiety for 4 weeks. The number150 of rainbow trout larva were fed with an average weight of 21.20 ± 1.31 g with the experimental treatments during 42 days breeding period. The results showed that the effect of treatments on weight and length growth, feed conversion ratio, daily growth ratio, specific growth ratio, survival rate, condition factor and survival rate were significant (P<0.05). Also, the effect of treatments on FER, PER, protein and fat percent carcass was significant (P<0.05). The diet containing probiotic with Bacilact compared to without Bacilact group improved the survival rate of rainbow trout. Regarding the higher SGR, the results showed that compensatory growth process in fish with 2 weeks of starvation and re-feeding with Bacilact is more than re-feeding without Bacilact. In conclusion, this study showed that probiotic (Bacilact) had a positive effect on growth and nutritional factors as well carcass composition in comparison to re-feeding without Bacilact in rainbow trout.

This study investigated the growth performance and fatty acid composition of Western whiteleg shrimp (Litopenaeus vannamei) fed with different levels of Dunaliella salina extract (DE) PL with an average weight of 0.86 ± 0.01g were fed with 3 types of diets containing 0.5, 1.5 and 1.5 g DE /kg diet and control diet (without DE) for 60 days. (A total of 4 treatments and 3 repetitions per treatment). The best weight gain (141.38 ± 21.35%), specific growth ratio (1.69 ± 0.55%) and protein efficiency ratio (2.79± 0.42%) were observed in shrimp fed with 1 g/kg of DE diet. In diets containing 0.5 and 1 g DE/kg feed, poly unsaturated fatty acid (PUFA) value significantly increased (p<0.05). Arachidonic acid (C20:4n-6), linoleic acid (C20:2n-6) and Docosahexaenoic acid (C22:5n-3) levels of shrimp receiving at 0.5 and 1 g DE/kg feed level were significantly higher than those fed with control diet(p<0.05). In conclusion, the incorporation of extract from D.salina 1 g/kg doses improves function of growth and fatty acid composition of body in L. vannamei shrimp.

In recent years, the use of probiotics has been considered as an ecological preventive approach to aquaculture, because of the perilous consumption of antimicrobials for humans and the environment, the use of alternative methods is increasing. In this study, we compared the efficacy of different methods of preparation of functional food containing native probiotic Takcell® on the growth performance of juvenile western white shrimp. For this purpose, post larvae of shrimps were fed in 8 experimental treatments in two ways: probiotic Supplemented and sprayed diets at doses of 108, 107, and 106 CFU kg-1 and probiotic-free diets for 40 days in tanks. All probiotic fed- diets showed better performance in relative growth rate, specific growth rate, survival rate and feed conversion ratio compared to control groups (p<0.05). The highest activity of growth indices was observed in spray treatment at a dose of 108 CFU kg-1. There was no significant difference with complementary diets (p>0.05). The results of this study showed that functional food containing native probiotic Takcell®, regardless of doses and preparation methods, resulted in improvement of growth and survival indices in western white shrimp, and the dose of 108 and 107 CFU kg-1 had the highest effect.

Iron and copper are two essential trace elements or micronutrients that play important roles in many vital biological processes, key enzymes and the immune system. In this study, the effects of feeding with different sources of iron and copper supplements on growth performance and some blood parameters of Schizothorax zarudnyi with an average weight of 23.97 ± 0.45 g were investigated. Within 60 days of study, dietary treatments were included fish fed with: 1) the basal diet without any copper and iron supplement, 2) diet containing 150 mg of mineral iron supplement per kg of diet, 3) diet containing 3 mg of mineral copper supplement per kg of diet, 4) diet containing 150 mg of mineral iron supplement and 3 mg of mineral copper supplement per kg of diet, 5) diet containing 150 mg of iron nanoparticles supplement per kg of diet, 6) diet containing 3 mg of copper nanoparticles supplement per kg of diet, 7) diet containing 150 mg of iron nanoparticles supplement and 3 mg of copper nanoparticles supplement per kg of diet. The results showed that supplementing diet with iron and copper improves the growth and blood parameters compared with the control; and iron and copper nanoparticles especially simultaneous use of them (treatment 7), act more effectively than their mineral forms; as the fish in treatment 7 showed the best growth and feeding results compared with the other treatments. Fish in treatment 7 also showed the highest values in all blood parameters and there were significant differences in hematocrit, hemoglobin and total amount of erythrocyte indices compared with the other treatments. MCV and MCH indices in treatment 7 exhibited significant difference compared with the control (P<0.05). According to the results of this study, simultaneous use of two nanoparticles of iron and copper leads to the improvement of growth and blood indices of Sistan’s loach more effectively than their separate supplementation or their mineral forms.

This experiment was carried out to evaluate the effect of adding of Microalgae Chlorella and Germinated Barely Powder in diet on growth performance microbiological counts of common carp. The study was assigned to depend on using of natural products as back to nature in fish feeding. The effect of adding microalgae Chlorella and germinated barely powder in common carp Cyprinus carpio diets with different levels for 84 days and the results revealed a significant role of both additives in each of fish Final wt., Wt. Gain, Specific and relative growth rate. No significant differences observed in FCR, the FER was higher significantly in control, T2 with 5 % Chlorella and T4 with 10 % Germinated barely. The total Bacterial and Enterobacteriaceae count/ CFU was increased in the additives treatments with increasing the levels, the T3 with 10 % Chlorella was higher than control and other treatments were 192.5 and 150 respectively. The control treatment without any addition was higher significantly in Total Bacterial count /CFU in common carp intestine samples, the T4 with 10 % Germinated barely was higher in Total Enterobacteriaceae count/CFU in fish Intestine samples. The highest Coliform bacteria in fish muscles and intestine recorded in T5 and the lowest in T3.
