Status Quo: Fish Feed Development in Japan

Abstract

Recently in Japan, a quick decline of sardine catch has had a great impact not only on mariculture where the raw fish has been used as a main feed, but also on fish meal production where sardine has been the major material. However, newly developed dry pellets for marine finfish have successfully replaced the raw fish and also opened up a possibility of utilizing alternative protein sources in the diets for mariculture species. Dry pellets formulated with various alternates are being gradually developed as grow-out diets. Current information on broodstock and larval diets is also presented here.
