Swimming crab has a lot of meat, is delicious, and has high nutritional value. Therefore, many farmers are breeding them, usually in major coastal areas. Swimming crabs can often be seen in coastal areas, but it is more difficult to eat fresh swimming crabs inland.

More and more people are starting to breed swimming crabs on a large scale, so how to breed swimming crabs? The details are as follows: Pond preparation swimming crab is a kind of marine animal, so the water quality requirement is that it needs salt water. It is necessary to choose a place with sufficient water and clean water without bacteria. It is best to have more abundant miscellaneous fish and shrimps, because it can provide enough natural food for swimming crabs, and have a good drainage and irrigation system to facilitate water exchange. Swimming crabs like to rest on the shore, so there should be enough space around the pond for swimming crabs to rest, preferably on a slope. Add an appropriate amount of fine sand to the bottom of the pool to satisfy the swimming crabs' love for diving in the sand. The water in the pond should not be too deep, about 4-6 meters long. Before preparing the crab seedlings, dry all the released water, splash the whole pond with quicklime for disinfection, eliminate the original bacteria, and prevent the crab seedlings from getting sick. Remove the dirt from the bottom of the pool, not too much, but leave a little. The remaining silt will then be loosened and exposed to sunlight for 3-5 days before being stored. When installing the pond, pay attention to oxygen, drainage, irrigation, escape and other facilities, and make all preparations.

A certain number of empty bottles, water pipes, etc. can also be placed in the pool body for rest. Before stocking, apply an appropriate amount of fertilizer in the pond to cultivate enough zooplankton. There should not be too much fertilizer, otherwise the water will become too fertile and affect the growth of crabs. After all the preparations were made, the crab fry began to be raised.

Crab seedlings raised in the same pond should be of the same size. Tree species of different specifications and sizes can easily bully small tree species, affecting their survival rate. The stocking density should not be too high, and the number of stockings per acre should not exceed 3,000. Otherwise, crabs will compete for food, fight, etc., affecting the growth and survival of all crabs. But it should not be too thin, as too little will reduce the vitality of the crab and easily affect the water quality. When feeding regularly, the water temperature during stocking should not be lower than 20 degrees, and the water temperature should be controlled to be constant to effectively improve the survival rate.
