Micropterus salmoides (Micropterus salmoides), also known as Micropterus salmoides and Micropterus macrocephalus, belong to Perciformes (Perciformes), Sunridae (Centrarchide), Hemicus (Micropterus), are native to the Missippi river basin in North America, are high-quality carnivorous freshwater fishes which are fresh and tender in meat quality, rich in nutrition, strong in disease resistance and rapid in growth, have the name of 'freshwater yellow fishes' and are introduced to various countries in the world for cultivation. Since the introduction of the method into China in 1983, researchers have conducted intensive research on micropterus salmoides and succeeded in artificial propagation in 1985. With the continuous improvement of the breeding technology and the increase of the promotion strength, the annual output of the largemouth black bass is in a remarkable rising trend, the market demand is also remarkably increased, the market prospect is good, and the industrial development potential and the space are large.
The laying season of the largemouth black bass is 2-7 months, 4 months is the full laying period, and the largemouth black bass is mainly bred in spring in the conventional production process. With the development of fishery production and the change of production mode, the fry bred only in spring can not meet the fishery production requirement, and the breeding in the same time can cause commercial fishes to be sold on the market intensively, thus causing the price of largemouth black bass to be lower. In addition, the breeding cost of farmers can be increased by single-season production, and meanwhile, the risk of disease rate improvement of old mouth weever is increased, so that the breeding work of the largemouth black weever fry in all seasons is developed according to market demands, the limitation that the largemouth black weever can only be bred in spring is broken through, the experience is accumulated for the gradual trend of the largemouth black weever to the full-season artificial breeding, and the demand of the largemouth black weever on fishery production is met.
