- Abstract
- The present study evaluated the potential use of bioprocessed protein concentrates (BPCs) as an alternative of fish meal (AF) in the diets of juvenile rainbow trout, Oncorhynchus mykiss and juvenile whiteleg shrimp, Litopenaeus vannamei reared in semi-circulating aquaria. In the first experiment, results demonstrated that dietary fish meal (FM) level could be reduced up to 30% by BPC in rainbow trout diet. The second experiment showed that BPC pre-treated with acid hydrolyses and/or added with shrimp soluble extract (SSE) showed better digestibility over other plant protein based ingredients such as soybean meal or protease enzyme treated fermented soybean meal, corn gluten meal (CGM), and commercially produced fermented protein concentrate (Soytide) meal in rainbow trout. The third experiment similarly dealt with FM replacement in whiteleg shrimp, the results revealed that FM could be substituted by BPC with acid hydrolyses and/or SSE supplements at a 30% replacement level without compromising the health status of shrimp. In the fourth and final experiment, results postulated that BPC with acid hydrolyses and/or added SSE had better digestibility than those of SM, CGM, or enzyme treated BPC diets. These research works have potential implications in high quality plant protein based feed ingredient development as an alternative of fish meal for sustainable production of two commercially important aquaculture species such as rainbow trout and whiteleg shrimp.
