The key to the success or failure of shoal-covered crabs on the tidal flat is the ability of the facilities to resist wind and waves, as well as the measures and effects of preventing flight. Therefore, farmers must patrol every day to watch. After every ebb tide, check whether the earth dam has water seepage or water leakage, whether the fence piles have collapsed, whether the fence has been damaged, if any problems are found, repairs should be promptly made and blue crabs should be active at night. Frequently, during high tides, it is easy to stimulate the nets to escape. When the tide overflows the dam, blue crabs turn around the fence. If there is a hole in the fence, groups of blue crabs will flee here. At this point, the nets should be repaired immediately. In addition, when the water quality is low in a small tidal pool, it is easy to make the crabs burrow and escape. It is also necessary to pay attention. The predators of the shoal purse seine crab mainly include tigerfish, Chinese pond pupa, and finger horse licks. They often eat during the crab shelling period. Therefore, during the breeding period, they can be exposed to tides during each tide period. The dry pool captures and removes predators, but it can keep the pelican and pike in the pool, which is beneficial for cleaning up sludge and baits at the bottom of the pool, and can coexist peacefully with the green crab and increase additional production.
