Domestic salmon are all imported. There is no salmon in China. The import price is definitely more expensive. The main import is Norwegian deep-sea salmon, so many illegal businesses in China sell other fish under the name of Norwegian salmon! It's just that the' domestic farmed salmon' that has been in trouble recently is actually not salmon, but rainbow trout. Rainbow trout is a kind of salmon and a close relative of salmon. There are many kinds of rainbow trout on the Qinghai-Tibet Plateau in China, but they are very cheap, so they are often used to pretend to be salmon. Salmon is the transliteration of salmon English, rainbow trout is far from salmon! Salmon is mainly produced in the Atlantic Ocean and the Pacific Ocean near the North Pole. It is common in Norway and Alaska in the United States, and there are also a few in Japan and Russia. Salmon is a highly migratory cold water fish. This kind of meat is rich in astaxanthin, because salmon eat shrimp. Generally, the overall price of salmon is around one catty in 80 yuan, and some of them are over 100 yuan. Most of the fish below 80 yuan are rainbow trout, including salmon in many cafeterias. Both wild and farmed salmon may contain parasites, so salmon will be frozen after being caught. The freezing temperature is generally: minus 20 degrees Celsius, around 7 days, minus 35 degrees Celsius, 15 hours or more, so that parasites can be killed and sashimi can be eaten raw. So be careful when eating salmon!
