The toxin of grouper is mainly concentrated in fish head, fish eggs, fish skin and internal organs. Grouper itself is not toxic, and its toxicity comes from ciguatoxin in seaweed.

Through the biological chain, it will be deposited in the species in the upper food chain (grouper belongs to the species in the upper food chain). In addition to cleaning up toxins, it also needs pollution.

geographical distribution

Grouper is widely distributed in tropical and subtropical waters of Atlantic Ocean, Indian Ocean and Pacific Ocean. There are 65 species of groupers of 1 1 genus distributed along the coast of China, including leptospira, Epinephelus americana, Epinephelus humpback, Epinephelus, Ophiopogon japonicus, Cynodon japonicus, Leptospira, Stichopus japonicus and Leptospira.

Mainly distributed in the East China Sea, Taiwan Province Strait and South China Sea of China, the common species are Epinephelus obliquus, Epinephelus leopard, perch humpback and green grouper. The Taiwan Province Strait, especially the waters of Penghu Islands, not only has the warming effect of Kuroshio tributaries, but also shallows, canyons and islands and reefs. Coral reefs are rich in resources, which are very suitable for the habitat of groupers, and the species of groupers are richer than those in the East China Sea and the South China Sea.
