Some papers have reported that cholesterol and glucosamine show an accelerating effect on the growth of prawn, Penaeus japonicus. In order to determine the optimum contents of cholesterol and glucosamine in the diet, their effect on the growth of prawn was examined in feeding experiments. The purified diet originated by the authors was used as the basal diet.1. In view of the fact that the prawn fed on cholesterol-fortified diets attained a remarkably high growth in comparison with the non-fortified diet, it is easily concluded that cholesterol should be compounded in the diet as an indispensable ingredient.The best relative growth in the experiments was obtained at a concentration of 2.1% in the diet.2. Glucosamine hydrochloride was used as a glucosamine source in the diets. The addition of glucosamine to the diet did not promote growth of the prawn, and this was especially clear in cases without cholesterol. It can be concluded that glucosamine is by no means an essential material to be compounded in the prawn diet.
