A: Catfish have beards on both sides of their mouths, such as catfish, local catfish, Yangtze catfish and silurus glanis. Catfish belongs to the bottom fish, which has a variety of feeding habits, mainly carnivorous small fish and shrimp, and also eats a small amount of vegetarian food. Catfish has fast yield, strong adaptability, tender meat and few thorns, which is especially suitable for the elderly and children. In particular, the Yangtze catfish (catfish) has the best taste, is natural and pollution-free, and is extremely expensive to sell in the market. The Yangtze River has been closed to fishing for ten years, and now there are almost no catfish in the market.
Then there is the carp, which also has a pair of beards on both sides of its mouth. Carp is also a bottom fish with thick meat, which many people don't like to eat. Red carp and golden catfish can be kept as ornamental fish. Their tentacles and tail feathers swing up and down in the water, which is very beautiful.
