Babylon shell and sea cucumber factory mixotrophic culture method

Abstract

The invention relates to a Babylon shell and sea cucumber factory mixotrophic culture method. Before seedlings releasing and cultivation of Babylon shells, sea cucumbers are released, water flows to activate aquiculture water and bottom sand; healthy Babylon shell seedlings are selected and are released after being disinfected; bait of the Babylon shells is mainly fresh small trash fishes, a strategy that the bait is stopped regularly and irregularly is employed, and the sea cucumbers do not need to be fed; a series of environment control strategies are combined to control the water quality and bottom sediment indexes to meet appropriate standards, and disinfectant and medicament are not used during the whole process. By changing the culture mode, the bottom sand deterioration is prevented by means of the biological action, the incidence rate of the Babylon shells during the culture period is effectively reduced, at the same time, the cost is reduced, the product varieties are increased, the culture products are healthy and pollution-free, and the Babylon shell and sea cucumber factory mixotrophic culture method plays an important role in developing the Babylon shell aquaculture industry.

Description

technical field [0001] The invention relates to a method for industrialized polyculture of dongfeng snails and sea cucumbers, which is suitable for the mixed cultivation of dongfeng snails and sea cucumbers under industrial culture conditions. Background technique [0002] Dongfeng snail (Babylonia sp), commonly known as flower snail and mud snail, is a mollusc gastropod. It is widely loved by people because of its delicious meat and rich nutrition. Because Dongfeng snail has great market potential and is suitable for industrial farming, it has broad development prospects. At present, it has become an important species of marine shellfish culture in the south of China. However, along with the development of the aquaculture industry, various diseases in the aquaculture process have gradually increased. Diseases have become an important factor restricting the development of Dongfeng snail industrial farming industry. In Hainan, malignant diseases have broken out for several ...

AI Technical Summary

Problems solved by technology

At present, the cause of disease in Dongfeng snail industrialized breeding is limited to speculation, and there is no reliable data support, and there is no research on the establishment of an early warning mechanism for related diseases.

Whether it is bacterial disease or shell-flesh separation disease, no feasible prevention and control method has been found so far. Even for bacterial diseases with a clear pathogen, the effect of drug treatment is very poor. One of the reasons may be that Dongfeng snails live in the sand layer, and drugs Difficulty penetrating the sand; another reason may be that the diseased snails were too sick to cure when the outbreak occurred
