New ideas on Prevention and Control of Shrimp Disease

Shrimp virus disease, a wide range of disease, rapid outbreak, high mortality, farmers talk about disease color change. To overcome shrimp virus disease has become a worldwide topic. In recent years, Europe, the United States, Japan and other countries have invested a lot of money and manpower to tackle key problems, and their research direction without exception is how to maintain the relative stability of shrimp growth environment. However, the seawater environment is dynamic, so this method is extremely difficult, and because of the high cost, it is difficult to have market promotion value. Recently, professors and experts from the School of Animal Science of Zhejiang University have discovered the pathogenesis of the virus: changes in the external environment mainly affect the blood and digestive system of prawns. If there is a problem with one of these two systems, the latent virus in the shrimp will be activated. According to this, the experts developed a unique way and adopted a different research direction from foreign countries: through biological agents to stabilize the digestive system and blood system of prawns, improve disease resistance and achieve the purpose of inhibiting the disease. The experts then devoted themselves to the development of biological agents, and after two years of hardship, they finally achieved success. In the experimental pond of the second farm of Damutu Culture in Ningbo, 113 mu of shrimp reached the standard of commercial shrimp after three months, and there was no abnormal disease.
