Technical Field
The invention relates to a micropterus salmoides culture pond capable of preventing and relieving fatty liver, a corresponding feed and a culture method.
Background
Micropterus salmonides (academic name) original Lateolabrax Micropterus (Lateolabrax), taxonomically belonging to Perciformes, the family Sudoidae. The origin place is in the fresh water lake in the America, and is introduced into China in the eighties of the twentieth century. It is delicious in meat quality and rapid in reproduction, so that many fishery farmers still prefer it. It is a kind of carnivorous fish, which can swallow the aquatic organisms such as fish and shrimp.
In order to seek to reduce the cost, people invent a plurality of special feeds to replace live baits, and the feeds have high fat and protein contents, fast growth of micropterus salmoides, and high economic benefit. However, the common bass eating the high-fat and high-protein food which is delivered to the mouth every day easily causes serious fatty liver, most prominently shows that a plurality of big belly fishes appear, and the liver of the common bass is almost completely changed into fat after the belly of the common bass is cut open.
The prior cultured micropterus salmoides generally suffer from fatty liver, the fat content in the fish meat is higher, and the eating of the fish meat is not beneficial to the health of human beings.
