Abstract
A 4-week feeding experiment was conducted with juvenile white shrimp Litopenaeus vannamei to compare the growth of shrimp fed different protein sources: fish meal (FM) and soybean meal (SM). By the end of the experiment, the shrimp grew to g (FM) and g (SM). The food and protein conversion rates were significant (P and , respectively. The proximate compositions of the entire body and edible part of the shrimp were similar between FM and SM, except for crude protein. The total amino acid levels were slightly lower in SM than FM, but the difference was not significant. During the experiment, the total ammonia, nitrate, and nitrite concentrations increased continuously in both groups and were slightly higher in SM than FM. In conclusion, soybean meal as a substitute for fish meal results in satisfactory growth and survival of white shrimp.
