Grouper is a grouper of the fish of the genus Epinephelus of the family Euphorbiae. There are 36 species on the coast of mainland China, 35 species in the South China Sea, 10 species in the East China Sea, 1 species in the Yellow Sea and Bohai Sea, 27 species in Taiwan, and 17 species in Hong Kong. About 15 species are commonly cultivated. In addition, grouper fish are also widely distributed in the Indian Ocean, tropical Pacific and subtropical waters. China’s sea cage fish farming started relatively late. In the late 1970s, Huiyang County and Zhuhai City in Guangdong Province carried out trials on fish cages in seawater cages, and stocked more than 20 fish such as grouper, carp and barramundi. Variety, a success. In 1981, it was transferred to productive farming and achieved remarkable production and economic benefits. In recent years, sea cages have developed rapidly. According to preliminary statistics, only the southern waters have exceeded 500,000 boxes (3m, 3m, and 3m), and aquaculture production has been greatly improved. However, the grouper has not been able to breed on a larger scale, mainly due to the shortage of natural seedlings, but artificial breeding is limited to several species such as green spot and gentian stone spot, and the quantity is not stable. With the growing maturity of artificial seedlings and the favourable price of grouper fish, groupers will be one of the major breeding species for sea cages in the future.
First, the ecological habits 1. Temperature: The optimum water temperature is approximately 22°C to 28°C. The water temperature below 18°C ​​is appetite diminished and remains motionless. The fish body below 15°C loses its balance.
2. Salinity: Grouper is a wide-salinity fish with salinity ranging from 11 to 44 ‰.
3. Habits: Grouper is a coastal warm water medium-lower fish, often inhabit coastal rocky reefs and sea areas, generally living in water depths of 40 meters to 50 meters. Is a carnivorous fish and has a residual diet, eat fish, shrimp, crabs, hunger when there is a fratricidal phenomenon, especially in the juvenile larvae stage, often ate than its smaller size of the same type, so when juvenile fish classification note.
