Groupers and beaked sea bass are found in the Western Pacific, Indian Ocean and Red Sea, and their natural habitat is rocky reefs, gravel and coral reefs near coastal islands. Grouper is a low-fat, high-protein high-quality edible fish, there is a saying that "tasted grouper, the world's fish are resting", and has also been promoted by Hong Kong and Macao as one of the four famous fish in China.
Groupers are ferocious carnivorous fish, they will open their mouths when feeding, using the negative pressure of the sea to generate suction, instantly swallowing the whole thing, they will use the tooth plate in the throat to grind the prey. Adults are not herded and are typical warm-water offshore reef-dwelling fish. Because its body is covered with beautiful patterns like stones, it is named grouper. Groupers have sexual transformation characteristics, basically females when they first mature, and then convert to males after a few years (the age of sexual transformation varies with species).
Here are a few common groupers!
< h1 class="pgc-h-arrow-right" > oblique bander</h1>
Commonly known as green spots, the head and body dorsal area are tanned, the abdomen shading is white, and countless orange-brown or reddish-brown dots are distributed in the middle of the head, body, and fins. There are 5 irregular, intermittent, ventrally forked diagonal bands on the surface of the body, a diagonal band and a black spot appear above the head, and the diagonal band can be seen in front of and below the eyes; the orange dots turn brown when exposed to air. Its growth is suitable for water temperature of 16 ~ 32 °C, the most suitable water temperature of 20 ~ 29 °C; with the increase of temperature, feeding intake increases significantly. The growth rate of oblique band grouper is much higher than that of red-spotted grouper and blue-spotted grouper, with bright body color, low oxygen consumption rate, high assimilation energy, less waste discharge, high conversion rate, stable market price, and more and more favored by consumers and farmers.
< h1 class="pgc-h-arrow-right" > blue grouper</h1>
Commonly known as the perch cat, is a warm water offshore bottom precious fish, the body of the fish is oblong oval, slightly flattened, generally 15 to 20 cm long, weigh 350 ~ 750g, the fins are gray-brown, the whole body is scattered orange-yellow spots, there are 5 dark brown transverse bands on the side of the body, 1 belt 2 belts are closely connected, 3 and 4 belts are located between the dorsal fin and the fin, 5 belts are located on the tail stalk, widely distributed in the western North Pacific Ocean, can be captured all year round. Blue grouper meat is fat and tender, fast growth, strong resistance to stress, at present, China's production of blue grouper in addition to the domestic fresh sales of the main export, not only best-selling and very high price, has become a foreign exchange-earning fishery.

The water temperature adaptation range of red spot grouper growth is 15-32 °C, and the suitable growth water temperature is 22-28 °C. For a long time, the fry required for the cultivation of red spotted grouper mainly rely on natural harvesting, and the overfishing caused by high economic value has greatly reduced the number of red spotted grouper, in addition to the direct reduction in the number of red spot groupers, overfishing has reduced the food of red spot grouper.
