Some or all of the visceral adipose tissue of cultured red sea bream turns yellowish brown, which is yellowish steatosis. The main cause of yellow lipidemia in red sea bream is caused by fish eating feed containing metamorphic lipids, especially when fed in summer, the feed is easily deteriorated by high temperature and ultraviolet rays. In addition, when sardines, jade tendons and fish are thawed as raw feed for red sea bream in the sun, the fat is easily rancid, if multivitamins are given. In terms of prevention, fresh feed should be fed as much as possible in summer.

The liver of cultured red sea bream is partly or entirely green, which is called green liver disease. The cause is also due to the ingestion of deteriorated feed. The prevention and control measure is to avoid feeding deteriorated feed and strengthen feeding management.
