Three experiments were conducted to investigate the effects of the replacement of fish meal with (1) de-hulled soybean meal, (2) soybean meal or (3) isolated soy protein on the growth of Litopenaeus vannamei. Juvenile white shrimps were fed with both isonitrogenous (34% crude protein) and isocaloric (2710 kcal/kg) diets. The replacement of fish meal with de-hulled soybean meal, soybean meal and isolated soy protein, was in 20、40、60 and 80%, respectively.The experiment duration was 6 weeks. White shrimps fed diets containing 80% fish meal replaced by de-hulled soybean meal had the worst feed conversion ratio (1.436) and survival ratio (88%).There were no significant differences in the weight gain of white shrimps fed with other replacement levels of de-hulled soybean meal. White shrimps fed diet containing 40% fish meal as protein source replaced by soybean meal had the higher significant weight comparing to those fed with other soybean meal replacement levels. In addition, there were no significant differences (P < 0.001) in the weight gain of shrimp fed with diets containing different replacement levels of isolated soy protein. The weight gain of white shrimps fed with diets containing isolated soybean protein ranged from 2827 to 3265%.
