In summary, fish meal is a high quality protein resource for Litopenaeus vannamei, and the experiments results of the apparent digestibility of dry matter, protein, AA and energy revealed ESBM, PNM and CGM are comparable to fish meal regarding bioavailability. However, through the differential combinations of extruded soybean meal, peanut meal, corn gluten meal and soy protein concentrate with fish meal, respectively, growth performance feed utilization reduced as content of FM decreasing; the activities of proteinase and lipase and the apparent digestibility of dry matter, protein, AA, lipid and energy decreased of Litopenaeus vannamei. As well as, the total protein and glucose content in serum decreased too, same as to the ACP and AKP activities. Decreased.in the growth, protein utilization, digestive enzyme activity, apparent nutrient digestibility, blood biochemical index and non-specific immunity, when exorbitanced proportion of plant protein mixture /(composed by:ESBM:PNM: CGM=38/%:17/%:45/%/) compounding with FM in the diets. Based on the different compounded proportion, balanced AA could reduce the negative effect, which caused by compounded of plant protein mixture and FM. In the control diet which containing 40/% protein and 30/% FM for white shrimp, the optimal proportion of ESBM, PNM, CGM and SPC, respectively, compounding with fish meal were 8.40/%:24/%, 3.83/%:27/%,9.44/%:21/% and 9.20/%:21/%, respectively, and the optimal proportion compounded of plant protein mixture and FM was 11.73/%:21/%.
