た。[Means for Solving the Problems] The present inventors have conducted extensive research to utilize unused marine biomass resources as sources thereof in accordance with the demand for feedstocks of highly unsaturated fatty acid compositions for fish feed. As a result, the red alga Fudarac, which has never been known to contain these higher polyunsaturated fatty acids, prevents an abnormal phenomenon in marine fish culture.
It has been discovered that PA exists as a component of a suitable usage form, and it has been elucidated that it is a suitable material.

After removing the protein part and the sugar part by extraction with, the step of removing and extracting saturated fatty acids and hydrocarbons from the product itself by SC-CO 2 extraction can be included. The higher polyunsaturated fatty acid composition obtained by the present invention can remove palmitic acid by about 10% as compared with the organic solvent method itself. As a result, EPA is about 40
