Abstract

A study carried out for reduction of fish meal in Beluga Huso huso diet. A basic diet based on 54% fish meal were formulated. A mixture based on corn gluten wheat and anchovy fish meal formulated similar to amino acid profile of basic diet at the levels of 20, 40, 60 and 80% as experimental treatments, fish meal (FM) (Basal diet) and corn gluten meal base included 20% replacement (CGM₂₀), 40% replacement (CGM₄₀), 60% replacement (CGM₆₀) and 80% replacement (CGM₈₀) with Similar protein (44%), energy (18 MJ / kg) and amino acid profiles. Beluga fish (Huso huso) with average weight of 167.6± 6.5g introduced in each experimental unit and were fed on experimental diets during a 10 –week culture period. Effect of these alternatives on growth indicators and liver tissue were investigated. Alternative food had no effect on fish growth indices and there was no significant difference in fish performance growth (P>0.05). No significant difference was observed in hepatosomatic index (P>0.05). Liver tissue was normal in fish fed FM, CGM₂₀, CGM₄₀, CGM₆₀ and a low damage observed in liver tissue such as cell necrosis, nuclear hypertrophy and hemorrhage. But, fish liver tissue fed by CGM₈₀ had higher abnormal liver damages such as lipid degeneration, cell necrosis, biliary stagnation and hemorrhage.
