The effect of dietary substitution of animal and/or plant protein sources for fishmeal on the growth and body composition of juvenile abalone was determined. Nine experimental diets in triplicate were prepared: Con, SM, PM, CM, SPM, MB, SM+CM, SM+SPM and CM+SPM diets. A 350 g kg⁻¹ fishmeal was included in the Con diet, and the whole fishmeal was substituted with a 580 g kg⁻¹ soybean meal (SM), 335 g kg⁻¹ poultry meal (PM), 370 g kg⁻¹ corn gluten meal (CM), 325 g kg⁻¹ silkworm pupae meal dehydrated (SPM), 590 g kg⁻¹ meat and bone meal (MB), the combined 290 g kg⁻¹ soybean meal and 180 g kg⁻¹ corn gluten meal (SM+CM), 290 g kg⁻¹ soybean meal and 160 g kg⁻¹ silkworm pupae meal dehydrated (SM+SPM) and 180 g kg⁻¹ corn gluten meal and 170 g kg⁻¹ silkworm pupae meal dehydrated (CM+SPM) diets respectively. All experimental diets were iso-nitronic and iso-lipidic. The survival of abalone fed with the SM and SM+SPM diets was higher than that of abalone fed with the CM, SPM, MB and CM+SPM diets. Weight gain of abalone fed with the SM+SPM diet was higher than that of abalone fed with all the other experimental diets, except for that of abalone fed with the SM+CM diet. The combined soybean meal and corn gluten meal (SM+CM) or silkworm pupae meal (SM+SPM) could be replaced with the whole fishmeal in the diet for abalone and improved its performance.
