Crabs raised in the north will most likely freeze to death, because crabs are mainly raised in the south where the climate is warm. Affected by the natural environment, the weather in the north is relatively cold in winter, and can even reach minus thirty or forty degrees. , the general breeding water surface will freeze, so the lack of oxygen will cause the crabs to die.

Even if special treatment is done and the breeding environment reaches a certain temperature, crabs will grow slowly and the quality of crab meat will be poor, so it is not recommended to raise crabs in the north.
