Grouper is a general term for groupers, groupers, gill perch and other fish in the family Bass. It has a large number of species, has a fairly complex ecological stratigraphy, and has a territorial and mimetic behavior, generally inhabiting multi-rocky reef caves and coral areas, mainly feeding on fish, shrimp, crabs, endpods, etc. Groupers are mostly hermaphrodites with sexual conversion characteristics, with all-line females at first sexual maturity and then males a few years later. Grouper is rich in nutrients, tender and white flesh, and is a low-fat, high-protein high-quality edible fish.
