Sažetak

Like other crustaceans, narrow-clawed crayfish (Astacus leptodacylus Eschscholtz, 1823) can change its diet to the available food during varied life cycles. Diet alteration can affect different biological indices of this species, therefore this study aims at studying changes in growth indices, hemolymph biochemical parameters and biochemical quality of its carcasses, which might occur during diet change of crayfish. The purpose of this experiment was to evaluate the effects of partial replacement of fish meal with soybean meal on growth performance, carcass quality and hemolymph biochemical parameters of narrow-clawed crayfish. 90 healthy adult narrow-clawed crayfish (W=35.50±4.05 g; TL=16.96±1.92 cm) were randomly distributed into 9 fiberglass tanks (200 L) and were fed for 45 days with three varied diets including: commercial shrimp diet, fishmeal-based diet (A) and soybean meal-based diet (B). The results show that changing the diet from animal protein to plant protein caused a significant decrease in the cholesterol and triglyceride levels in hemolymph, as well as carcass fat of the crayfish nourished with B diet when compared with the crayfish fed with A diet. No significant changes of hemolymph levels of glucose, AST and ALT were found between different treatments during this experimental period. In conclusion, it was found that though growth performance reduced, the increased rate of soybean meal in diet from 0.0% to 76% had no adverse effects on biochemical parameters.
