Crayfish are aggressive, so try to spread them in a big basin, and put a proper amount of water in the big basin, which can not only reduce the number of deaths, but also let crayfish discharge their own garbage. The big basin is to leave space for crayfish to facilitate activities. Moreover, crayfish prefer dark and humid places, and black plastic bags can be covered on the basin to reduce tension and reduce the chance of fighting.

Living environment:
Shrimp has strong adaptability. According to the investigation, it can survive in lakes, rivers, ponds, canals and paddy fields, and even in some water bodies where it is difficult for fish to survive. Lobster has a strong adaptability to dissolved oxygen in water. It can not only climb ashore in an anoxic environment, but also lie on its side on the water with the help of floating plants or aquatic plants in the water and breathe through its gills to survive.
Lobsters have a strong tolerance to hypoxia, and can climb ashore for gill breathing and survive in an anoxic environment. The pH value of water is in the range of 5.8 ~ 9, and it can still survive normally when the dissolved oxygen is lower than1.5 mg/L/L. The normal growth requires that the dissolved oxygen be above 3 ml/L.
Lobsters have a strong tendency to flow, like fresh water and flowing water, go upstream and live in groups. In aquaculture ponds, groups often gather around the water inlet. In rainy days, shrimp can stay or escape on the shore for a short time against the current, and climb ashore to live when the water environment is not suitable, so the breeding ground should be fenced to prevent escape.
