Background
The swimming crab is named as , and the swimming crab is named as blue crab because the head shell is shaped like a shuttle and the center of the shell is provided with three protrusions. The portunus trituberculatus has the advantages of large size, fast growth, high use value, delicious meat, rich nutrition, large edible proportion, high nutritive value, and medicinal values of clearing heat, dispelling blood, nourishing yin and the like. Mainly produced in yellow sea, bohai sea and east sea. As the living standard of people is improved, the sea crabs cannot meet the increasing demands of people, so artificial feeding is started. The traditional portunus trituberculatus seedling raising process is capable of changing a large amount of water, consuming a large amount of energy and increasing production cost. At present, natural sea areas are polluted frequently, sea water is eutrophicated, a large amount of bacteria and fungi are propagated, and great influence is brought to the seedling raising of the aquatic products. Frequent water changes are carried out in the seedling raising process, and the energy in the jumping body is required for the larvae to adapt to the new environment, so that the energy for growth is reduced, and the cultivation time is prolonged. The change in the survival environment of larvae can increase the threat of pathogenic microorganisms to larvae, which may cause diseases. In order to prevent and treat crab diseases, a large amount of pesticides, antibiotics and some high-residue chemical synthetic drugs are used by many breeding owners, and chemical fertilizers and growth promoting hormones are added into feed for pursuing growth speed and yield, so that the quality of crab products is reduced safely and linearly, both adult portunids and portunids in seedling raising stage like climbing everywhere, no hard shell is formed on the body surface of the portunids immediately after hatching, the body is very fragile, and seedlings are well protected by the development in water, and a seedling raising pond is needed.
However, when the swimming crabs are used in the young and young swimming crabs, the individuals and the tendencies of the swimming crabs are mature, and excreta generated by metabolism are more, and the existing treatment mode is usually a mode of manually salvaging by using a net bag, so that the blindness of the treatment mode is higher, the treatment is not thorough, and a great deal of harmful microorganisms are always caused to breed due to long-term deposition of excreta at the bottom of the swimming crabs. Therefore, how to invent a novel swimming crab breeding pond and a breeding method thereof to improve the problems becomes a problem to be solved urgently by the person skilled in the art.
