What's the best fish?

Su Mei fish is delicious, tender and smooth, and it is a rare dish. Su Mei fish tastes good, and the price is naturally beyond the reach of ordinary seafood. The person in charge of a hotel told the reporter that a humpback wrasse (0.5 kg in size) costs more than 400 yuan in a hotel, and some hotels cost more than 500 yuan, but the purchase price of humpback wrasse is also quite high, and the wholesale price is half a kilogram of 400 yuan. At present, the highest wholesale price has reached 450 yuan. Due to the high price, the sales of the hotel's Su Mei fish are not large, mainly for some high-standard banquets, and rich diners will order Su Mei fish on the table.

Humpback wrasse is the most precious large fish in the genus Epinephelus, belonging to warm-water marine fish. China is mainly distributed in the South China Sea and other places, but its resources are limited and its catch is small. It is said that most humpbacked wrasse sold in the market are imported from Southeast Asian countries. Humpback whales reach maturity at the age of 5 and can live for at least 30 years. The color of humpback wrasse is black and white when it is young, olive when it is young, and blue-green when it is mature. Because there are two black lines behind the eyes that go straight to the head, the fish is named "Su Mei".
