PURPOSE: To obtain from seaweed the title composition for fish feed for preventing an abnormal phenomenon in ocean culture by mixing a highly unsaturated fatty acid obtained from the lipid part of a red alga 'Fudaraku' with a saturated fatty acid.
CONSTITUTION: The composition comprises a liquid formed from 38-55 pts.wt. highly unsaturated fatty acid obtained from the lipid part of a red alga 'Fudaraku' and 30-50 pts.wt. fatty acid. A highly unsaturated oil or fat with advanced function, such as eicosapentaenoic acid(EPA), cannot be formed in the body of fish. Accordingly, the conventional feed for the cultivation of fish, etc., which contains no or little EPA tends to result in an abnormal growth of a fry. The composition prepared from the seaweed can prevent the abnormality when added to the feed for the cultivation of fish, etc.
