According to the process of the present invention, fish bodies, from which the internals and/or skins are optionally removed, are treated with a protease to give a gain in soluble nitrogen contained in the treated material based on the total nitrogen contained in the starting material of 3 to 50% to thereby give a slurry; and fish bones, fish oil, partially decomposed fish porteins and an aqueous solution containing water-soluble components are separated and recovered from said slurry.
