Abstract:
Silver perch (Bidyanus bidyanus. Mitchell) of 65g average weight were reared at high density under controlled conditions on diets containing 24.8% and 40.6% protein. Diets were fed at 2% or 4% of the fish biomassday-1. Both protein concentrations and feeding level of the diet influenced growth and proximate composition of the fish at the end of the 50-day growth trial. Energy requirement for maintenance for these fish was found to be 77 calBW-0.8 and for each unit of energy retained 3.78 calBW-0.8 needed to be supplied. and for each gram of protein retained per metabolic body weight 5.04g were required. The results indicate that it is possible to obtain the same weight increment when feeding a 24.8% protein diet at a level of 4% body weight day-1 as compared with only 2% body weight day-1 of a 40.6% protein diet. This study indicates that the nutritional requirements for early grow-out are similar to those found in a previous study with juvenile silver perch and adds information concerning the required relationships between dietary amino acids. The results provide information required for further refinement of nutrition for this species.
