Identification and Prevention of Yellow Fat Disease and Green Liver Disease in Farmed Red Sea Bream
What are yellow fat disease and green liver disease in farmed red sea bream? How are they prevented and treated?
In farmed red sea bream, when part or all of the visceral adipose tissue in the body turns yellow-brown, this is yellow fat disease. The main cause of yellow fat disease in red sea bream is the fish consuming feed containing deteriorated lipids; this is especially the case in summer feeding, when feed is prone to deterioration under the effects of high temperature and ultraviolet radiation. In addition, when sardines, sand lance and anchovy used as raw feed for red sea bream are thawed in sunlight, their fat tends to become rancid; if a multivitamin is given. For prevention, fresh feed should be given as much as possible in summer.
In farmed red sea bream, when part or all of the liver is green, this is green liver disease. The cause is also the consumption of deteriorated feed. The prevention and control measure is to avoid feeding deteriorated feed and to strengthen feeding management.
