•Fermented plant proteins sources (FSCB) could replace 30 % of fishmeal in shrimp diet.•FSCB could increase growth, feed utilization and disease resistance in whiteleg shrimp.•Replacement of fish meal by FSCB could enhance water quality parameters in aquaculture. Six different types of solid state fermented plant proteins and soy protein concentrate were evaluated as fish meal replacers in whiteleg shrimp, Litopaeneus vannamei. In the first experiment, eight experimental diets consisted of a control diet without fish meal replacement (CON), and seven other diets replacing 30 % of fish meal with fermented soybean meal with Bacillus subtilis (FSMB), sterilized FSMB (FSMBS), fermented soybean meal and corn gluten meal with B. subtilis (FSCB), sterilized FSCB (FSCBS), fermented soy protein concentrate with B. subtilis (FSPB), fermented soybean meal with lactic acid bacteria (FSML), and soy protein concentrate (SPC). At the end of eight weeks, weight gain, specific growth rate and serum lysozyme activity of shrimp fed FSMB and FSCB diets were significantly higher than those of shrimp fed CON and FSML diets (P
