The effect of varying levels of Nymphaea leaf meal on the growth and survival of common carp, Cyprinus carpio was investigated. In a feeding trail of 45 days, three experimental diets containing nymphaea leaf meal at 300, 400 and 500g kg-1 level of incorporation were fed to triplicate groups of 10 fish each. The conventional feed used in India, consisting of a mixture of groundnut oil cake and rice bran in 1:1 ratio served as the control. Best growth in terms of weight gain (35.2g), specific growth rate (4.67), protein efficiency ratio (PER) (2.7), feed conversion ratio (FCR) (2.5) was obtained for the test diet with 400g kg-1 nymphaea meal inclusion level. However no statistical difference was observed between the three experimental diets. Digestive enzyme activity and digestibility studies also indicated the same pattern. Thus the results of the present study indicate that a diet of 300g kg-1 overall protein with nymphaea meal included at 400g kg-1 can elicit good growth response and survival in common carp.

This study was conducted in indoor, aerated plastic tubs to estimate the digestibility of dry matter and nutrients by the carps, Labeo fimbriatus (Bloch, 1795) and Cyprinus carpio Linnaeus, 1758, from three feed ingredients viz., azolla, soybean meal and silkworm pupa incorporated at levels ranging from 0-40% in a diet comprising equal amounts of rice bran and groundnut oil cake using crude fibre as the marker. Activity of the major digestive enzymes was also estimated in the gut of fish at the end of the experimental trial. Utilisation of azolla protein was comparable with that of control diet up to 20% incorporation in both L. fimbriatus and common carp. Major nutrients from soybean were better utilised up to 40% incorporation by the two species. Protein digestibility from silkworm pupae increased at 20% incorporation and decreased at 40% in L. fimbriatus, while fat and nitrogen-free extract digestibility was higher at 20-40% incorporation. In common carp, higher digestibility of protein and fat was recorded at 10-30% inclusion levels of silkworm pupa.

The study examined the growth performance, hematological and digestive enzymes of Clarias gariepinus juveniles fed Cirina forda meal (CFM) based diets in the laboratory for a period of 10weeks. Five iso-nitrogenous (30%) experimental diets were formulated at various levels of CFM inclusion levels of 0% (control), 10%, 20%, 30%, 40% and 50%, designated as diets Q, A10, B20, C30, D40 and E50 respectively. Fish fed the CFM based diets showed mean weight gain (MWG), specific growth rate (SGR) and protein efficiency ratio (PER) comparable to the control diet. There was significant differences in the digestive enzyme activities of the fish as the CFM level in the experimental diets increased. Protease and maltase activities significantly increased, with diet C30 recording the highest maltase activity (4.37) while the cellulase and glucanase activities of the fish significantly (P<0.05) reduced. There was no significant difference (P>0.05) between the PCV and RBC of the blood of the fish fed the various diets. Highest RBC (2.75 x106/µL) was obtained in fish fed the control diet while the lowest (2.55 x106/µL) was recorded in the fish fed diet E50. The White Blood Cell count and the Neutrophils of the fish fed the trial diets were not significantly higher (P>0.05) than those of the fish fed the control diets. From the results of this experiment, it is concluded that up to 50% inclusion level of Cirina forda meal in the diet of Clarias gariepinus was tolerable for good growth and physiological well-being of the fish.

Nursery evaluation of catla spawn was carried out by feeding three iso-nitrogenous diets (35% protein in raw and cooked form) for a period of 30 days. The three test diets (treatments) in raw form were: T1 - groundnut oil cake (GOC) + rice bran (RB) + vitamin-mineral (V-M) premix; T2 - GOC+RB+fish meal (FM) + V-M premix, T3 - GOC+RB+prawn meal (PM)+V-M premix. The diet groups GT1, GT2 and GT3 respectively were same feed combinations in cooked form. Incorporation of prawn meal as animal protein source led to significantly higher final weight, final length, % weight gain, specific growth rate (SGR) and protein efficiency ratio (PER) compared to diet with and without fish meal incorporation. Whereas, diet containing fish meal improved the fry growth and survival rate only when it was cooked. Cooked diet either with fish or prawn meal incorporation led to better fry growth over the respective non-cooked diets, revealing the advantage of cooking process for better nourishment in catla fry during nursery phase.

The objective of the study was to find out the effect of partial replacement of fish meal in the diet of Labeo rohita juveniles. In this experiment, the data pertaining to growth, survival rate, feed conversion ratio, protein efficiency ratio of L. rohita at partial replacement of fishmeal with E. crassipes were evaluated. For that purpose fry of approximately equal weight (57.97mg ± 1.25) were distributed in groups of 15 to each four aquaria at 0% (T1), 10% (T2), 20% (T3), 30% (T4) and 40% (T5) inclusion levels of aquatic macrophyte, Eichhornia crassipes. Maximum mean weight gain (235.25 ± 11.04 mg) was observed in T1 and minimum (165.06 ± 10.93 mg) was observed in T5 at the end of the experiment. Among the treatments tested, the highest survival (89.99% ± 1.93) was recorded in treatment T1 and minimum was found in T4 (79.99% ± 2.72). Lowest FCR was recorded in treatment T3 (2.02 ± 0.39) and highest was found in T5 (3.08 ± 0.59). Higher SGR was observed in treatment T1 (297.15 ± 18.78%) and minimum was observed in T5 (182.74 ± 18.45%). The study revealed a decrease in the growth performance indices as the percentage of water hyacinth increases. In present study also there was not much difference in growth rate upto 20% incorporation of E. crassipes in the diet. Also, significant difference was observed among treatments with respect to feed utilization (P<0.05).

A 60 days indoor growth trial was conducted to study the effect of dietary supplementation of biofloc meal on growth and survival of juvenile GIFT tilapia. Four isonitrogenous and isoenergetic experimental diets (32% crude protein) were prepared using biofloc meal at different inclusion levels viz., 0 (T0), 20 (T1), 30 (T2) and 40% (T3). A commercial diet (T4) was used for comparison. The feeding trial was conducted in 15 nos. of 40 l plastic troughs in triplicate, utilising GIFT tilapias weighing an average of 2 g. During the experimental period, water quality parameters were measured and recorded daily. The mean value of water temperature, pH, dissolved oxygen, salinity, ammonia-N, nitrite-N, nitrate-N, hardness and alkalinity recorded in the experimental systems were 28.5°C, 8.1, 5.5 ppm, 4.5 ppt, 0.03 ppm, 0.07 ppm, 11 ppm, 630 ppm and 162.5 ppm respectively. Among the biofloc meal enriched diets, diet T1 with 20% biofloc yielded the best results in terms of average body weight gain, feed conversion ratio (FCR), specific growth rate (SGR), protein efficiency ratio (PER) and feed efficiency ratio (FER). The mean body weight gain recorded in T1 was 25.28±0.81 g. The results demonstrated that biofloc meal is a potential ingredient that can be incorporated in GIFT tilapia diet at 20% level for better growth performance.

Abstract The feasible strategies to keep up the growth and wellbeing of aquatic organisms by using beneficial dietary additives is highly recommended. Among these additives, β-glucan (BG) and mannanoligosaccharide (MOS) were examined on common carp performances in the current experiment. For 80 days, carps fed four diets with 0%, 1%, 2%, and 3% BG/MOS (1:1) and distributed in four groups (triplicates). Higher final weight and weight gain (P < 0.05) were detected in carps fed 1%, 2%, and 3% of BG/MOS than the control group. The feed conversion ratio showed lower values (P < 0.05) in carps-fed BG/MOS mixture at 2%, and 3% than 0% and 1% levels. The activities of amylase, lipase, and protease were higher in fish fed BG/MOS mixture than the control group. Interestingly, fish fed BG/MOS mixture had markedly increased villi length and width with branched villi integrity. Further, the count of goblet cells was increased (P < 0.05) in groups fed BG/MOS mixture than carps fed the basal diet. The hemoglobin and hematocrit levels and the counts of red and white blood cells were higher in carps fed BG/MOS mixture than the control with the highest counts in 3% level. Additionally, the blood total protein, globulin, and phagocytic activity were higher (P < 0.05) in groups received BG/MOS mixture at 3% than the control. The lysozyme had a higher value in 1% group than the control (P < 0.05). Therefore, using the mixture of BG/MOS at 2-3% is suggested for improving the growth rate, intestinal health, blood health, and immunity of common carp.

AbstractThis study evaluated the effects of grape seed extract (GSE) on the growth performance, immune response, and disease resistance of common carp (Cyprinus carpio). Fish were distributed in four groups and fed diets with varying levels of GSE at 0, 10, 20, and 30 g/kg for 56 days. The final length in fish fed with 20 and 30 g GSE/kg diet significantly increased in comparison with the control group (P<0.05). The final weight and weight gain of fish fed with GSE were statistically higher than the control diet, while the feed conversion ratio was lower in GSE groups than the control. Hematological parameters did not statistically enhance with GSE supplemented diets (P>0.05). However, fish fed with 30 g GSE/kg diet displayed a higher WBC count significantly than the other group (P<0.05). The serum total protein and globulin in fish fed with 20 g GSE/kg diet significantly increased compared to the control (P<0.05). A similar pattern was noticed in results for serum and mucus lysozyme activity with a significant increase in fish fed with 20 and 30 g GSE/kg diet compared to the control (P<0.05). Total antibody levels in serum and mucus samples were also increased in fish by dietary GSE with maximum levels by 20 and 30 g GSE/kg diet. Besides, mucus protease activity was higher in fish received 20 and 30 g GSE/kg diet with maximum level shown in fish fed with 30 g GSE/kg diet compared to the control group (P<0.05). Meanwhile, all groups showed higher mucus antibacterial activity against Aeromonas hydrophila with the highest activity in 30 g GSE/kg diet in comparison with the control group. The cumulative mortality was 36.67% when fish fed with 30 g GSE/kg diet and challenged with A. hydrophila. However, the mortality rate was 40% and 53.33% in fish fed 20 and 30 g GSE/kg diet, respectively. This study suggests that supplementation of GSE could significantly enhance the growth performance, immune responses, and disease resistance against A. hydrophila in common carp.
