An 8-week feeding trial was conducted to evaluate the potential use of vegetable protein based ingredients as a fish meal replacer in diets for juvenile rainbow trout, Oncorhynchus mykiss. Ten isonitrogenous and isoenergetic diets were formulated to contain high quality fish meal as positive control (+), low quality fish meal as negative control (-) and four different kinds of vegetable protein ingredients as alternative of fishmeal (AF-A, B, C & D) at the levels of 30% and 50%. The vegetable protein ingredients were prepared by different processing techniques using soybean meal (SBM) or corn gluten meal (CGM). The diet AF-A was fermented by Bacillus spp., diet AF-B was pre-treated acid hydrolyses; whereas diet- C & D were supplemented with water soluble attractants. Fish averaging 15.4 ± 0.03 (mean±SD) were randomly distributed into 30 aquaria as groups of 15 fish and fed the experimental diets in triplicate at satiation twice daily on dry matter basis. At the conclusion of the feeding trial, fish growth, non-specific immune response, digestive enzymes and nutrient digestibility will be analyzed and discussed.
