The search for alternative protein sources in aquaculture nutrition is still trending as the use of costly traditional feed stuffs in aquaculture diet formulation is no longer sustainable. The present study investigated the effects of partial and total dietary inclusion of cashewnut meal on growth, haematology, carcass composition, serum biochemistry and intestinal histology of juvenile African catfish Clarias gariepinus (Burchell, 1822). Soybean meal (SBM) was substituted with cashewnut meal (CM) at 0, 50 and 100% in formulated fish diets. A total of 135 juveniles of C. gariepinus (30.25± 1.02 g; 16.08±0.34 cm) were randomly assigned to three dietary treatments (0, 50 and 100% CM based diets) at a stocking density of 45 fish per treatment and further randomised into triplicates of 15 fish per replicate. The feeding trial lasted for 56 days and fish were fed twice daily at 5% body weight. Statistical analysis was carried out for all the parameters evaluated in this study. Fish group fed 50% CM based diet had the best growth performance and haematological profile when compared to 100% CM fish group and the control group. Insignificant changes in serum biochemical parameters were observed in CM fed fish groups when compared to the control. Histological examination of fish intestinal morphology revealed no adverse changes in the cellular structure of mucosal layer and villi in 50% CM fed fish, while mild histo-morphological changes were observed in 100% CM fed fish group. Significant increases in villi length and weight were observed in fish group fed CM based diets when compared to the control. The findings of the present study revealed that partial replacement (50%) of soybean with cashewnut meal improved growth performance and haematological profile of C. gariepinus.

The main objective of the study was to investigate the effect of partial replacement of soybean meal (SBM) protein with sunflower meal (SFM) protein on growth performance, feed utilisation, survival and body composition of GIFT tilapia. Fish weighing between 1.03±0.01 and 1.19±0.02 g were stocked in in plastic troughs (50 l) at a stocking rate of 15 fishes per trough. Percent replacement of SBM by SFM on the basis of crude protein was 0% (control), 10% (SFM10), 20% (SFM20) and 30% (SFM30). Diets were fed to fish at the rate of 5% of the total fish biomass, daily for a period of 60 days. Fish fed with SFM 20% and SFM 30% sunflower meal had best performance in terms of weight gain, specific growth rate, protein efficiency ratio, feed efficiency ratio and feed conversion ratio (p<0.05). Analysis of fish whole body composition revealed that with increasing dietary SFM levels, whole body protein, ash and moisture contents showed significant difference among dietary treatments (p<0.05). Fish fed with SFM 30 diet showed the best growth performance compared to fish fed with the control diet.
