Description
Technical Field
The invention relates to industrial fry production of aquaculture, in particular to a fry collecting facility and a method for industrial fry culture of rapana venosa.
Background
The Rapana venosa is commonly called as a varroa venosa and a conch, belongs to the phylum mollusca, gastropoda and ospirdae, belongs to the genus rhodospirus, has the adult shell height of 11-12cm, and is distributed in Bohai sea and yellow sea in China. The foot is particularly fat, the taste is delicious, the nutrition is rich, and the foot is even popular for people, and the economic value is high. In recent years, with the decline of offshore resources and the successful sale of commodities of the variety in domestic and foreign markets, the economic value of the variety is continuously improved, and the price of the living body is 20-40 yuan/kg at present.
At present, the rapana venosa has great market demands on Bohai sea and yellow sea coastline in China, some scientific research units and seedling raising enterprises try to carry out artificial seedling raising from the last 90 th century, but most of the rapana venosa fails, the seedling raising efficiency is extremely low, and the industrial scale is not realized, so that the artificial culture cannot be carried out on a large scale.
At present, the main factor causing the breeding technology of rapana venosa offspring seeds to be not over-related is that the problem of food habit conversion of rapana venosa larvae is not well solved. The food habit transformation means that the rapana venosa larva needs to be transformed from eating plant baits such as chlamydomonas to eating animal baits in the transformation process. The food habit transformation is a very critical stage in the development of the rapana venosa, and most of the larval death occurs in the development stage. In the industrial breeding process of the rapana venosa, most of the currently used animal baits are muddy flesh of bivalve shellfish (such as clams, oysters, mussels and the like). The use of the bivalve meat paste as animal feed is easy to cause water quality deterioration, so that the larvae die in a large scale and the seedling culture fails.
