An 8‐week feeding trial was conducted to evaluate the effects of replacing fish meal ( FM ) with soybean meal ( SBM ) and peanut meal ( PM ) on growth, feed utilization, body composition and haemolymph indexes of juvenile white shrimp L itopenaeus vannamei, B oone . Five diets were formulated: a control diet ( FM 30) containing 30% fish meal and four other diets ( FM 20, FM 15, FM 10 and FM 5) in which protein from fish meal was substituted by protein from SBM and PM . The dietary amino acids of diets FM 20, FM 15, FM 10 and FM 5 were equal to those of the diet FM 30 by adding crystalline amino acids (lysine and methionine). Each diet was randomly assigned to triplicate groups of 30 shrimps (initial weight = 0.48 g), each three times daily. The results indicated that shrimp fed the diets FM 15, FM 10 and FM 5 had poor growth performance and feed utilization compared with shrimp fed the control diet. No difference was observed in feed intake, survival and body composition among dietary treatments. The plasma total cholesterol level of shrimp and the digestibility of dry matter, protein and energy contained in the diets decreased significantly with increasing PM and SBM inclusion levels. Results of this study suggested that fish meal can be reduced from 300 to 200 g kg −1 when replaced by a mixture of SBM and PM.
