Like African crucian carp, shad will die when the water temperature is lower than 7℃, and will not eat when it is lower than 14℃. They prefer to live in the water temperature of 25-30℃, that is, the shad are produced in Guangdong, Hainan, southern Fujian, tropical Yunnan, Yidu, Guangxi and other places where the winter temperature is lower than 7℃, which is not suitable for the survival of shad.
Extended data
The main producing area of shad is China, which is common in the Pearl River Delta, Hainan and other areas with high water temperature, with low breeding cost and large output. Shad is rich in protein, vitamin A, calcium, magnesium and selenium.
Economic value: Because of its tender meat, delicious taste, large output, high output, moderate price and excellent quality, it is a best seller in the market. Most of the cultured shad collected in Guangdong Province are frozen with live fish, and the eyes of the frozen fish are still protruding and bright, just like live fish. In addition to the general eating method, fish balls can also be made for family consumption. Canned lobster sauce herring produced by this factory, like frozen herring, is sold all over the country.
