PURPOSE:To obtain a feed for rearing, having sufficient binding properties to prevent contamination of the seas and rivers even in the case of an increased ratio of a live feed and effective in growing cultured fish by containing salts coated with a highly water absorbing and water-insoluble substance. CONSTITUTION:A conventionally well-known formula feed is mixed with a live feed to produce a feed for rearing fish. In the process, e.g., a highly water absorbing resin, such as starch-polyacrylonitrile graft copolymer, in an amount within the range of 0.01-20wt.%, preferably 0.1-10wt.% based on the total amount of the feed for rearing fish is added and salts, e.g., vitamins or minerals, in the formula feed are coated with at least one of water-insoluble substances, such as fats and oils or fatty acids, having >=30 deg.C melting point and added thereto. |
