At present, there are crayfish habits such as crayfish (Procambarus clarkii), green shrimp, freshwater prawn and freshwater Macrobrachium rosenbergii. Crayfish are good at "taking things as they are", and rivers, lakes, reservoirs, rice fields and ponds can all be home to crayfish. When the water temperature rises in spring, crayfish often move in shallow water. It lurks in the deep water when it is hot in midsummer. In winter, crayfish spend their time in caves to prevent attacks from other animals.
Crayfish not only has strong feeding ability, but also has the habit of gluttony and competing for food. In the case of high breeding density or hunger, crayfish will have a "tragedy" of killing each other, and crayfish and young shrimps that have just been shelled often become "meals on the plate" of "strong" lobsters.
June-August every year is the most "plump" time for crayfish. At this time, the crayfish shell is hard and thick, which is also the best time for people to catch and enjoy.
