Efficient ecological method for breeding rachycentron canadum in deep-water anti-wave cage

Abstract

The invention discloses an efficient ecological method for breeding rachycentron canadum in a deep-water anti-wave cage; the method comprises the following steps: (1) selection of a breeding sea area; (2) cage and supporting facilities; (3) selection, transportation and stocking of fingerlings; (4) a bait feeding technology; and (5) feeding management. Compared with the traditional breeding methods, such as inner bay fish row breeding, the efficient ecological method for breeding the rachycentron canadum in the deep-water anti-wave cage, disclosed by the invention, has the advantages as follows: a sea area breeding space is expanded; an inner bay sea area environment is protected; and high survival rate of bred rachycentron canadum, low bait coefficient, high growing speed, short breeding period, small breeding risk, high yield of pollution-free rachycentron canadum, good quality, good mouthfeel and the like are achieved.

Description

technical field [0001] The invention relates to a method for cultivating cobia in the aquaculture industry, in particular to an ecologically efficient method for cultivating cobia in deep-water storm-resistant net cages in the open sea area of ​​the South China Sea, and belongs to the technical field of fish aquatic organisms in agricultural aquaculture. Background technique [0002] Cobia (Rachycentron canadum), commonly known as cobia, sea dragon fish, etc., belongs to Osteichthyes, Perciformes, Rachycentridae, Rachycentron, is a medium-sized warm-water seawater fish, distributed in Tropical waters such as the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean are distributed in the southern sea areas such as Sanya, Beihai, and Taiwan in my country. Cobia has the characteristics of fast growth, large size, strong disease resistance, high yield, delicious taste, and high nutritional value. It has obvious breeding benefits and market advantages. It has become one of the ...

Problems solved by technology

At present, due to the blind expansion of the scale of breeding in most of the inner bays and coastal areas in southern China, a large number of cages are distributed in a row in the breeding area, the density of the cages is too high, the water flow is not smooth, and it is easy to cause hypoxia; And long-term feeding of chilled bait and fodder, resulting in a large amount of residual bait accumulated in the sea, forming blackened silt, and accompanied by a large amount of industrial and domestic wastewater, which made the water pollution in the breeding sea area more serious. These have become Causes of disease floods and red tides

Due to the serious pollution and frequent occurrence of diseases in the inner bay breeding sea area, this has led to the abuse of a large amount of antibiotics and other drugs, which makes the cultivated cobia have a strong smell, fat and bloated, poor meat taste, serious drug residues, low market recognition, and low sales prices. cheaper
