Özet

A total of 300 juvenile crayfish (13.0 +/- 0.03 g) were randomly distributed among 5 dietary groups (n=60, 3 replicates) held within 15 x 500 L-1 fiberglass tanks connected to a recirculation system (RAS), at 20 crayfish per tank. Each group was fed for 12 weeks one of five experimental diets where the main protein sources were: 1) control, fish-meal-based diet (FM, 48% of the diet); 2) 10% FM + 52.5% poultry by-product meal (PoM); 3) 34.5% soybean meal + 34.5% corn gluten meal (Pmix); 4) 34.5% PoM + 32.soybean/corn gluten meal mix (PoM/Pmix); and 5) 10% FM + 27.5% soybean + 27.5% corn gluten meal (FM/Pmix). The results demonstrated that there were no significant differences among diets in terms of growth and feed utilization efficiency. Muscle amino acid profile of redclaw crayfish fed the FM diet had the highest level of total essential amino acids, followed by FM/PMix, Pmix, PoM/Pmix, and PoM diets. Particularly, in all experimental groups, the highest essential amino acids (EAA) were lysine, arginine, and leucine. Based on these findings, we conclude that redclaw can perform well with FM-free vegetable diets and PoM-based diets although more research is needed into the total composition of EAA and FA in muscle.
