Soybean Meal-Aquaculture

Two experiments were conducted to determine the optimum inclusion level of dehulled soybean meal as a fish meal replacement in the diet of olive flounder (Paralichthys olivaceus). The isonitrogenous and isoenergetic experimental diets were formulated to contain 50 percent crude protein. The treatments consisted of soybean meal replacing fish meal, amino acid supplementation and the addition of dietary attractants. The diets were fed to five or forty-five gram fish for eight or ten weeks. Results indicated that dehulled soybean meal could replace up to 20 percent of the fish meal without amino acid (lysine and methionine) or attractant supplementation; and up to 30 percent replacement with amino acid and attractant supplementation in the diet of fingerling and growing olive flounder. (This is another report showing that soybean meal can replace fish meal in nutritionally adequate diets for various species of fish. The “keys” are diet formulation and the economic incentive to replace the fish meal in these diets).
