Embodiment 1

[0024] Clean up the silt in the breeding pond, use 125 kg of quicklime per mu to spray the whole pond for disinfection, and drain the pond water for full exposure. If it is a mud bottom, spread a 2-3 cm layer of fine sand on the beach, and then pile up 2-4 sand piles in the pool, each with an area of ​​8-10 square meters. The width of groove is 2.5m, and depth is 0.4m; Then, introduction is 1.0m until the beach surface water level in the breeding pond through the seawater filtered through mesh; On the 10th day of the culture of Penaeus japonicus, it was found that Penaeus japonicus was sick, and the water in the culture pond was discharged to be level with the beach surface, and the Penaeus japonicus and swimming aquatic animals that were sick would be discharged into the annular groove with the water flow; Put bleaching powder in the ditch for concentrated anti-virus, after 2-3 hours, put the collection net in the drain of the annular ditch, drain the water in the ring ditch,...

Embodiment 2

[0026] Clean up the silt in the breeding pond, use 125 kg of quicklime per mu to spray the whole pond for disinfection, and drain the pond water for full exposure. If it is a mud bottom, spread a 2-3 cm layer of fine sand on the beach, and then pile up 2-4 sand piles in the pool, each with an area of ​​8-10 square meters. The width of groove is 2.5m, and depth is 0.4m; Then, introduction is 1.0m until the beach surface water level in the breeding pond through the seawater filtered through mesh; On the 20th day of P. japonicus culture, drain the water in the culture pond until it is level with the beach surface, and the diseased P. japonicus and swimming aquatic animals will be discharged into the annular groove with the water flow; then put them in the annular groove. Bleach powder is used for centralized anti-virus. After 2-3 hours, a collection net is placed at the outlet of the circular groove, the water in the circular groove is drained, and the dead organisms are collecte...

Abstract

The invention discloses a method for cutting off the propagation of infectious diseases of marspenaeus japonicas.The method includes the steps that a culturing pond is provided, wherein a beach face and an annular groove are formed in the culturing pond, the beach face comprises a sand layer, and pond water in the annular groove can be completely drained; marspenaeus japonicas are put into the culturing pond; in the first culturing period, pond water in the culturing pond is drained till the water level is flush with the beach face, wherein in the draining process of pond water, healthy marspenaeus japonicas can go into the sand layer, and pathogenetic marspenaeus japonicas and swimming aquatic animals can be drained into the annular groove along with water flow; a chemical is put into the annular groove for centralized sterilizing; after 2 hours to 3 hours, a collecting net is placed at a water draining opening of the annular groove, pond water in the annular groove is completely drained, and dead organisms are collected and deeply buried; filtered sea water is led into the culturing pond till the water level is flush with the beach face, the sea water in the annular groove is completely drained again, and finally filtered sea water is fed into the culturing pond till the water level of the beach face is 0.5 m-1.0 m.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cutting off the transmission of infectious diseases of Penaeus japonicus. Background technique [0002] Penaeus japonicus is commonly known as flower shrimp, car prawn, and spotted prawn. Its meat is tender and nutritious. It is suitable for breeding in areas with high salinity. It has strong resistance to dry dew and is suitable for sale as fresh and live shrimp. The price is relatively high. One of the three major shrimp farming species. The prevention and control of infectious diseases is the key factor for the success or failure of Penaeus japonicus farming, and its main route is through the shrimp, crabs, copepods and other crustaceans carrying or developing diseases in the pond. Although a large number of scholars have done a lot of work on the prevention and treatment of Penaeus japonicus disease, it has played a great role in promoting the development of aquacultu...
