Factorization culture method for garrupa

Abstract

The invention discloses a factorization culture method for garrupa. The method comprises the following steps of (1) cement pool design: the bottom of the pool is in a small slope form, a water discharge opening is arranged at the lowest part of the pool bottom, and the bottom pollution discharge is convenient; and in addition, a water discharge opening is also arranged in a position with a distance being 50cm away from the pool surface, and some mucus secreted by the garrupa floating at the upper layer can be conveniently discharged; (2) culture water preparation: the sea water is subjected to sand filtering and ultraviolet ray sterilization; (3) fish fry selection: fish fries longer than 10cm with the strong vigour and no nervous necrosis virus are selected; (4) garrupa culture: feed is put and fed every day, the water level can be properly raised before the feeding, the feeding quantity is proper when the garrupa is eighty percent full, after eating of the garrupa, a part of water is properly changed, bacillus is mixed with the feed for feeding twice every week, and people need to pay attention to the sun shading when the illumination is strong; and (5) the fish separation is carried out once every two monthes, the fish fries with great specification differences are separated to be fed, and in addition, the density is well regulated. The factorization culture method for garrupa provided by the invention has the advantages that the survival rate of the garrupa can be improved, the feeding factor is reduced, and the feeding cost is reduced.

Description

technical field [0001] The invention relates to a breeding method, which belongs to the technical field of aquaculture, in particular to a method for high-efficiency industrialized grouper farming. Background technique [0002] Grouper is a warm-water, wide-salinity, large and medium-sized carnivorous fish. It is a rare species that is cultivated in fish ponds or cages near the sea in our southern region. Grouper is a high-grade seafood with high protein and low fat, and it is also the first-class delicacy for people's festive banquets. Due to the fact that there are not many domestic breeding areas, the breeding area is small, and the traditional farming methods are backward, the supply of products is in short supply, which is far from meeting the needs of the domestic market. [0003] Tens of thousands of groupers are imported from abroad every year to meet the needs of big cities such as Shanghai, Beijing, Guangzhou, and Shenzhen. In recent years, grouper market prices ...

Problems solved by technology

[0004] A few years ago, industrialized abalone farming quietly emerged in Hainan Province. However, due to the degradation of abalone germplasm, frequent breeding diseases, and the weak market, the abalone farming industry suffered heavy losses, causing most abalone farms to stop production, and a large number of abalones were industrialized The breeding sites and facilities are idle, and the idle abalone breeding ponds in Hainan Province are about 500,000 cubic meters
