Overwintering Management Experience for Broodstock Breeding Ponds in Crayfish Aquaculture
Throughout the entire overwintering period, broodstock basically do not feed and consume a great deal of energy. Therefore, before overwintering, feeding must be intensified to strengthen the broodstock's constitution, store the necessary nutrients for safe overwintering, and increase the overwintering survival rate. When the water temperature drops below 10°C, broodstock basically enter burrows to overwinter and rarely emerge to activity. At this time, the water level should be appropriately raised to ensure there is water or moisture in the burrows, but the water depth must not exceed the burrow entrance; it should be slightly lower than the entrance. Otherwise, the broodstock will emerge from the burrows and choose new places to dig. Once the broodstock have basically entered their burrows, spread a thin layer of plant straw along the water's edge around the pond perimeter, such as rice straw, reeds, cattails, etc. First, to keep warm; second, to provide a hiding and overwintering place for the juvenile crayfish produced before the broodstock overwinter.
