Life habits:
Crayfish has a wide adaptability and a wide suitable growth temperature, and can grow and develop normally when the water temperature is 10-30℃. It can also resist high temperature and cold, can tolerate high temperature above 40℃, and can also survive the winter safely when the temperature is below-14℃. The crayfish grows rapidly. Under the condition of suitable temperature and sufficient bait supply, it can reach sexual maturity and meet the specifications of commercial shrimp after more than two months of breeding.
Like many crustaceans, the growth of crayfish is accompanied by molting. When molting, they usually look for hidden objects, such as water grass or under plant leaves. After molting, the maximum weight gain can reach 95%. Generally, sexual maturity can be achieved after molting 1 1 time, and sexual mature individuals can continue to molt.
