<p>It is intended to provide fish feeds making it possible to fed fishes in a favorable state and obtain fished having activated adrenal cortex which cannot be achieved by using the conventional fish feeds. 30 to 300 ppm of polyphenol is added to fish feeds containing 10 to 200 ppm of carotenoid. The weight ratio of carotenoid to polyphenol (carotenoid : polyphenol) is controlled to 10 : 300 to 200 ppm : 30 ppm.</p> |
