Embodiment 1

[0027] A method for cultivating pollution-free sea bass, comprising the following steps:

[0028] a) Select the sea area: choose a sea area with a water depth of more than 5 meters, smooth tides, and strong wind and waves. In the present embodiment, during concrete operation, select depth of water 6 meters, sea area flow velocity is 1.0m / s, and flow velocity in the net cage is 0.1m / s after the flow blocking measure.

[0029] b) Detection of water environment factors: water quality conforms to NY5052, water temperature: 8°C-30°C, salinity: 13-32; transparency: 0.2m-3.0m; in this example, water temperature 14°C, salinity 16, transparency 1.0 m.

[0030]c) Select the cage and make the layout: select the cage without nodular mesh and net clothing, the cage specification: (3.0~5.0)m×(3.0~5.0)m×(2.5~3.0)m, that is, according to the fish fry Size, choose cages of different specifications such as 3.0m×3.0m×2.5m, 3.0m×3.0m×3.0m, 4.0m×4.0m×3.0m, etc., the mesh length is 3mm~10mm; ever...

Abstract

The invention discloses a pollution-free cultivation method of lateolabrax japonicus. Through selecting a sea area and adopting a flow stop measure, the flow speed in a net cage is controlled within 0.2 meter per second, model selection and setting are carried out on the net cage, a floating type net cage with knotless meshes is adopted, a main harbor road and auxiliary harbor roads are arranged between the net cages, lateolabrax japonicus fry stocking, adult fish feeding, feed and feeding, daily management, disease control, harvesting, transportation and the like are designed, strict monitoring and detection are carried out at each stage during the cultivation period, the growth environment and the growth condition of the lateolabrax japonicus are controlled, the feeding condition of the lateolabrax japonicus is detected, and a garbage collection and processing device is provided, so that the cultivation of the lateolabrax japonicus is pollution-free and non-hazard, and the lateolabrax japonicus cultivated through the cultivation method is totally cultivated in sea water, the cultivated lateolabrax japonicus has the characteristics of bright body color, tender meat quality, delicious taste, rich nutrient and the like, and the pollution-free cultivation of the lateolabrax japonicus is implemented.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating pollution-free sea bass. Background technique [0002] Lateolabrax faponicus (Cuvier)], also known as seven-star perch and sea perch, is a wide-temperature, wide-salt, ferocious carnivorous, valuable economic fish, and is the main species of mariculture. It has the characteristics of bright body color, tender meat, delicious taste and rich nutrition, and is favored by consumers. In breeding, the perch has the characteristics of fast growth, less disease, wide adaptability, high price and good benefit. [0003] Cultivation of perch is becoming more and more popular in the aquaculture industry. Aquaculture will mean pollution. How to realize pollution-free production has become a major problem. [0004] Chinese patent literature (announcement date: December 29, 2004, announcement number: CN1557148A) discloses a method for converting freshwater culture...
