AI Technical Summary
The use of waterproof, gelatinous bottoms in traditional crayfish breeding ponds leads to poor growth and high mortality rates in berried crayfish. Furthermore, manual selection is inefficient, making it impossible to achieve large-scale breeding and early market availability of crayfish seedlings.
Bottom nets are installed at the bottom and side walls of the pool, and multiple small-aperture fixing devices are laid to construct artificial nests. Combined with water purification components and artificial nests, this promotes the berried shrimp to enter the nests for concentrated hatching.
This method effectively prevents berried shrimp from burrowing into the pond bottom, reduces mortality, enables centralized collection and hatching of berried shrimp, lowers manual screening costs, and meets market demand for early market access for crayfish.
