Background
Micropterus salmonides, named Micropterus salmonides by Latin school, other name, Lateolabrax japonicus, Black Bass, an animal belonging to the phylum chordata, the subgenus vertebrates, the class Osteichthyes, the subclasses Aphidae, the order Perciformes, the family Echinochaeidae. The Micropterus salmoides inhabit water areas with low turbidity and aquatic plant distribution, such as lakes, shallow water areas of reservoirs, creeks of swamp areas, stagnant water areas of rivers, ponds and the like. It is usually hidden in underwater rocks or branches, and has the habit of occupying land and small range of motion. In pond culture, people like to live in a still water environment with sand or sand mud which is not turbid and move in a middle and lower water layer. The sex is more tame, do not like jumping, and is easy to be frightened. The micropterus salmoides have a wide suitable temperature range, can survive at the water temperature of 1-36.4 ℃, begin to eat at the temperature of more than 10 ℃, and have the optimal growth temperature of 20-30 ℃. The water quality requires that the dissolved oxygen per liter of water is more than 1.5 mg, and has stronger hypoxia resistance than weever and mandarin fish. The young fish is in the movement of the cluster, and the adult fish is scattered. The original place of micropterus salmoides is pure fresh water, but the water body with the pH value of 6-8.5 can adapt to salinity below 10 per mill as proved by test culture. The micropterus salmoides are mainly carnivorous fishes, have strong predation property and large food intake, are frequently independently foraged and like prey on the small fishes and shrimps.
At present, micropterus salmoides are mainly cultured in a pond culture mode.
