Abstract
The favorable contents of protein and lipid were detected in compound food used for raising a young rockfish, S. thompsoni. The favorable protein content is 47% in lipid-excluded compound food; addition of lipid effectively accelerates the growth of fish. The effect of lipid appears to annex more than 10%. Pollack oil shows its effect at 15-21.degree. C; at higher temperatures, 23-24.degree. C, corn oil is more effective for growth. The higher the content of pollack oil in food, the higher content of fat is in muscles of reared fish.
