How to raise crayfish artificially

From June to August every year, crayfish is the most "plump" time, and it is also the best time for people to catch and enjoy it. Green, shallow beach, this water area is where Lao Gan often catches lobsters. According to foreign biology textbooks, crayfish like to live in dirty places, and the dirtier they are, the bigger they get. In fact, this is a very dirty food, which is rich in pathogens, such as pathogenic microorganisms and parasites. Why can scarlet crayfish survive and reproduce in dirty mud, while reddish prawns are not easy to survive even in clear water? Scientific research has proved that the content of astaxanthin in the body is positively related to its ability to resist the harsh external environment, which means that the higher the content of astaxanthin in the body, the stronger its ability to resist the harsh external environment. The content of natural astaxanthin in Bordeaux crayfish is several times that of prawn. Therefore, crimson crayfish can survive and reproduce in dirty mud, while reddish prawns are not easy to survive even in clear water.

[Edit this paragraph] Artificial farming

Crayfish are omnivores, mainly eating plants. Small fish, shrimp, plankton, benthos and algae can all be used as its food. The breeding ability of crayfish is not strong, and crayfish breed 1 time a year. Shrimp farmers say that he can catch three or four hundred Jin when he is alone at most, but there are thousands of shrimp farmers like him in Dongting Lake waters. Every day, about 30 tons of crayfish are sent from Yuanjiang market to all parts of the country.
