Combined method of stereo ecological polyculture mode and prevention and control of hepatopancreatic necrosis disease and white spot syndrome

Abstract

The invention discloses a combined method of a stereo ecological polyculture mode and the prevention and control of hepatopancreatic necrosis disease and white spot syndrome. Specifically, 3 days before adding prawn seeds, 200 scatophagus argus fries with length of 3-5cm and 300 siganids fries with length of 2-3cm are added into every Mu of a breeding pond; when prawn seeds are to be added, a prawn seed addition amount is 80000-100000 seeds / Mu; when prawn length reaches 4-5cm, 5-6 Nile perch with length of 8-10cm and 10-15 hybrid giant tiger groupers with length of 8-10cm are added into every Mu of the pond. According to the invention, fishes with different feeding habits are cultured with prawns at a same time, such that diseases and weak prawns are eliminated in time, prawn disease infection source is eliminated, and a water cleaning function is realized. A polyculture mode of prawns and fishes with suitable specifications is started from a breeding early-mid stage, such that a prawn disease infection source is cut off, and hepatopancreatic necrosis disease and white spot syndrome outbreak is prevented. The breeding mode is optimized, such that prawn breeding success rate is improved. The method provided by the invention is suitable for the breeding of prawns such as litopenaeus vannamei, marsupenaeus japonicas, penaeus monodon and the like.

Description

Technical field [0001] The invention relates to a method for the combined prevention and control of hepatopancreas necrosis and leukoplakia syndrome in a three-dimensional ecological polyculture mode, and belongs to the technical field of aquaculture. Background technique [0002] Shrimp aquaculture is the pillar industry of my country's marine aquaculture. It began to develop rapidly in the 1980s, and its annual output continued to rise, and the output remained at around 1.3 million tons this year. However, the stocking density continues to increase, the breeding environment is deteriorating, and the incidence of disease is high. The problem of shrimp diseases is still the main bottleneck for the development of shrimp aquaculture. At present, the main measures to solve the problem of shrimp diseases include improving the ability of shrimp disease resistance, improving the shrimp breeding environment and cutting off the transmission route of shrimp disease pathogens. Since the ...
