First, choose the overwintering pool crab species wintering pool to be quiet, leeward sunny, good water retention performance, pool depth of 1.5 to 2 meters, an area of ​​2 to 4 acres. Before use, use 100kg of clear lime for disinfection per acre.
Second, the selection of crab species overwintering crab species should be physically strong, uniform specifications, complete limbs, no disease without injury, no attachments. 75 to 100 kg of stocked crabs per acre.
Third, water quality management pool water quality should be fresh, high dissolved oxygen. The water depth is kept above 25 meters to maintain a higher water temperature. If the water level is too shallow, it must be replenished in time; prevent the crab species from being frostbite and freezing to death. If the water quality is too fat, new water should be replaced in time to prevent the death of crab species.
Fourth, appropriate feeding during the winter, such as sunny weather, water temperature above 4 °C, crab species will be a small amount of feeding, can be fed a small amount of chopped small fish, shrimp, animal blood clots and other bait to supplement nutrition.
