Grouper is divided into sea red spot, eastern star spot, western star spot and so on. This one caught by Guangdong fishermen is a medium giant grouper, commonly known as dragon fan.
The giant grouper likes to inhabit the shallow sea in the reef plate, with the deepest depth exceeding 60 meters, and usually likes to eat crustaceans such as small fish and shrimps at the bottom.
Due to the limitation of receptor type and structure, the giant grouper is not fast in swimming, and is used to preying by surprise attack. When hungry, it can swallow squid 1 meter long in one gulp!
The magic thing is that the giant grouper is hermaphrodite, and the gender will change! When the sexual development is mature, the giant grouper appears as a female, and then turns into a male in the second year, so the male grouper is less than the female grouper.
The adult giant grouper can grow to more than 2 meters in length and weigh more than 200 kilograms, which is a proper "Big Mac"! This giant grouper is not "extremely rare". In May 20 16, Shimou bought a giant grouper from fishermen, which was 2.7 meters long and weighed 305 kg. The purchase price reached 120 yuan/kg, and the total cost was 36,600 yuan!
20 14 1 month Malaysian fishermen once caught a giant grouper weighing more than 400 Jin, which was bought by a local Chinese at a high price of 1. 1 wanlingji.
The giant grouper is the longevity among fish. A giant grouper weighing more than150kg has at least forty or fifty years' experience in sea life, so it is generally difficult to catch it. A giant grouper weighing 380 kilograms once appeared in Hong Kong's fishing market, and the local media reported this grouper with a 200-year-old birthday star.
Of course, because of the delicious taste and high price of grouper, many fishermen now start to cultivate grouper, but there are still some problems in the cultivation of medium giant grouper, which need to be overcome a little bit.
