The effects of one diet contain of 42 percent soybean meal (experimental treatment with 38 percent crude protein) in comparison with commercial diet (control treatment with 39 percent crud protein) at 6 earthen ponds, each one with the area of 0.4 ha, ( 2 treatments and 3 replicates in each treatment) on growth indexes of western white shrimp (Litopenaeusvannamei) was determined. The initial weight of post larvae was 0.008±0.001g, with density of 25 ind/m2 . The mean of culture periode in the experimental treatment and control treatment was 115 dayes, The mean of growth rate (GR) in the experimental treatment and control treatment was 15.70±0.88g and 15.60±0.52 g, respectively and significant statistically difference was between those (p<0.05). The food conversion ratio (FCR), in the experimental treatment and control treatment was 1.80 ±0.08g and 1.76±0.06 g, respectively, and significant statiscally difference was between those (p<0.05). Specific growth rate (SGR) in the ex.....
