Problems solved by technology

Since the cultivation of fry and later breeding are carried out in different areas, the environmental conditions vary greatly. At the same time, fry need to be transported for a long distance, which not only greatly increases the cost of breeding, but also easily produces stress reactions or infection of various diseases, which seriously affects The economic benefits of farming

Embodiment 1

[0022] (1) Selection of aquaculture sea area: choose a sea area with a certain wind barrier or relatively small wind and waves, smooth water flow, sufficient water body exchange, not affected by fresh water and pollution sources in the inner harbor, fresh water quality, and relatively stable water quality environment; when the tide is low The water depth is 10-15 meters, and the water quality in the breeding sea area should meet the following conditions: salinity 20-30‰, water temperature 18-32°C, pH 7-9, transparency 8-15 meters, and dissolved oxygen above 5 mg / L;

[0023] (2) Setting of net cages: deep-water net cages are set in the mariculture area, and the corresponding deep-water net cages are fixedly installed in the mariculture area. At least one layer of netting is arranged on the net cages. The nets should be smaller than the diameter of the fish fry; before the nets are installed, they should be cleaned and disinfected; when the water flow in the sea area is fast, the...

Embodiment 2

[0029] The difference between this embodiment and Example 1 is that the feed is different. The feed used in this embodiment consists of the following components in parts by weight: 20 parts of fish meal, 20 parts of rapeseed meal, 30 parts of soybean meal, 25 parts of flour 10 parts of shrimp shell powder, 3 parts of fish oil, 0.8 parts of calcium hydrogen phosphate, 0.6 parts of fungus polysaccharide, 2 parts of cork powder, 2 parts of Houttuynia cordata, and 0.8 parts of clove.

Embodiment 3

[0031] The difference between this embodiment and Example 1 is that the feed is different. The feed used in this embodiment consists of the following components in parts by weight: 30 parts of fish meal, 30 parts of rapeseed meal, 25 parts of soybean meal, 15 parts of flour 15 parts of shrimp shell powder, 5 parts of fish oil, 0.5 parts of calcium hydrogen phosphate, 0.9 parts of fungus polysaccharide, 3 parts of cork powder, 3 parts of Houttuynia cordata, and 0.5 part of clove.

Abstract

The invention provides a super-large deep-sea net cage culture method for golden pomfrets. The deep-sea net cage is arranged in a sea area, fry can be directly put into the net cage to be cultured until finished fish grow up, and meanwhile, the water flow speed is controlled and feed is optimized, so that the morbidity and mortality in the culture process are reduced, and the survival rate of thegolden pomfrets is improved; in addition, the weight of the golden pomfrets can be increased to a certain extent, the yield is greatly increased, and the economic benefit is obvious. In addition, thewhole culture process of the fry is completed in the sea area, continuous water flow and substance exchange are maintained in the sea area, and the deep-sea net cage has self-cleaning capability. Therefore, drugs are not needed for disease control in the culture process of the golden pomfrets, the quality of the produced finished fish is close to the quality of wild golden pomfrets, and no drug residue exists.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a super-large deep-sea cage culture method for golden pomfret. Background technique [0002] The scientific name of golden pomfret is oval pomfret, and the local name is yellow wax pomfret and golden pomfret. The body of this fish is flattened, oval, and the anal fin is slightly equal to the second dorsal fin, both of which are significantly longer than the abdomen. The head side is flat, the caudal peduncle is thin, and the body is covered with small round scales, which are not easy to peel off. Golden Pomfret is rich in nutrition, high in protein, rich in unsaturated fatty acids, and has the effect of lowering cholesterol. At the same time, golden pomfret is rich in trace elements selenium and magnesium, which can prevent cardiovascular diseases such as coronary arteriosclerosis, delay the aging of the body, and have the effect of preventing cancer. On the usual table, you can oft...
