| Abstract: | Growth in Macrobrachium rosenbergii was studied using diets in which plant sterol was substituted for cholesterol. Weight changes, mortality, molt cycle, and sterol levels were observed. Results of a study of the effect of increasing the percentage of plant sterol in the diets were inconclusive due to cannibalism among experimental animals. In a subsequent study, all animals were held in separate containers. In that study, a level of 0.5% plant sterol showed no signigicant difference in weight change or molting cycle from the same amount of cholesterol in a prepared diet fed the shrimp. Plant sterols seemed to successfully substitute for cholesterol in this study. |
