Problems solved by technology

[0002] Flower perch, also known as flower perch and seven-star perch, belongs to Perciformes and Lipidaceae in taxonomy. Because it breeds and grows in the coast, it is different from California perch and osmanthus perch that grow in freshwater, so it is also called sea bass and flower perch. It is one of the four famous fish perch, chia, mandarin fish and mandarin fish in the waters of the Xijiang River. The meat is firm and delicious, and rich in nutrition. Every 100 grams of fish meat contains 17.5 grams of protein, 3.1 grams of fat and multiple vitamins. It is cultivated in offshore cages It is an ideal culture method for sea bass, but the current culture technology still needs to be improved

Embodiment Construction

[0021] The present invention will be further described with an embodiment below:

[0022] A kind of storm-resistant net cage culture method of sea bass of the present invention, comprises the following steps:

[0023] (1) Selection of breeding sea area

[0024] It is better to choose open sea waters for breeding. The brackish waters where the tide reaches are better. The water quality salinity can be in the range of 5%-15%.

[0025] (2) Cage selection

[0026] The anti-wind and wave cages are combined into a group of four and arranged longitudinally along the tidal flow direction, so that water flow channels are formed between each group of cages; the shape of the cages is a square, the diameter of the cage is 20-30m, and the height is 8m. The distance between each net cage is 80m; the depth of the net entering the water is 6m, and the mesh size changes with the size of the fish. The effective breeding water body of each net cage is about 6000 cubic meters, and the net ca...

Abstract

The invention discloses an anti-wave cage breeding method for lateolabrax japonicas and belongs to the technical field of mariculture. The method includes the following steps of 1, aquaculture sea area selection, 2, cage selection, 3, stocking of lateolabrax japonicas flies, 4, feed feeding, 5, breeding management, 6, daily management and disease prevention and treatment. According to the method, through scientific arrangement of the cages, each group of cages are longitudinally arranged in the flowing direction of tidewater, so that blocking of water flow by the cages is the minimum, the situation that water flow is unsmooth, water quality is deteriorated, and lateolabrax japonicas are dead can be avoided, the lateolabrax japonicas can be always in a healthy living environment, and the survival rate of lateolabrax japonicas is increased.

Description

technical field [0001] The invention belongs to the technical field of mariculture, and in particular relates to a method for cultivating sea bass in a net cage against wind and waves. Background technique [0002] Flower perch, also known as flower perch and seven-star perch, belongs to Perciformes and Lipidaceae in taxonomy. Because it breeds and grows in the coast, it is different from California perch and osmanthus perch that grow in freshwater, so it is also called sea bass and flower perch. It is one of the four famous fish perch, chia, mandarin fish and mandarin fish in the waters of the Xijiang River. The meat is firm and delicious, and rich in nutrition. Every 100 grams of fish meat contains 17.5 grams of protein, 3.1 grams of fat and multiple vitamins. It is cultivated in offshore cages It is an ideal culture method for sea bass, but the current culture technology still needs to be improved. Contents of the invention [0003] The technical problem to be solved b...
