Problems solved by technology

[0004] In recent years, many practitioners have copied other fish industrialized recirculating aquaculture methods to raise snakeheads. However, due to the lack of understanding of the ecological characteristics of snakehead culture, the breeding results are not good.

Embodiment 1

[0039] There are 2 groups of breeding workshops, a total of 16 cement ponds of 4m*4m, and 16 cement ponds of 5m*5m, with a total breeding area of ​​656m 2 , the pool water depth is kept at 0.70m, and the total aquaculture water body is 459m 3 . Each pool is equipped with drainage and oxygenation facilities, and maintains micro-flow water. The highest water temperature for aquaculture is 31.5°C, the lowest is 19.8°C, and the annual average water temperature is 26.7°C. The cultured species are the clouded snakehead and the hybrid snakehead. The average stocking size is 13.5cm, 39g, and the average stocking density is 65 fish / m 2, A total of 42640 tails were stocked in one year. The feed is bait fish such as dace and artificial compound feed, and no drugs are used during the breeding period. The breeding survival rate is 92.3%, the average size is 590g / tail, and the total breeding output is 23220Kg. The average aquaculture output per square meter is 35.4kg, and the aquacultu...

Embodiment 2

[0041] The water volume ratio of the breeding workshop and the water treatment system is about 1:2. The breeding workshop consists of 10 circular glass tanks with a radius of 3m and 10 cement pools with a height of 1.2m and a depth of 0.80m. Each pool is equipped with drainage and oxygenation facilities, and maintains micro-flow water. The ecological sewage collection and treatment pool, biological filtration pool, and microbial enrichment pool are built next to the workshop, with an area of ​​1.0 mu and a water depth of 1.5m. The highest water temperature for aquaculture is 31.2°C, the lowest is 19.5°C, and the annual average water temperature is 26.1°C. The cultured species are Snakehead and Hybrid Snakehead. The average stocking size is 13.8cm, 42g, and the average stocking density is 59 fish / m 2 . The feed is bait fish such as dace and artificial compound feed, and no drugs are used during the breeding period. The breeding survival rate is 93.5%, and the average size i...

Abstract

The invention belongs to the technical field of aquaculture, and discloses an industrialized external-circulation water ecological breeding method for Oxyeleotris. Concretely, an industrialized external-circulation water ecological breeding system is adopted for breeding and comprises a breeding workshop and a water treatment system, wherein the water treatment system comprises an ecological sewage collection and treatment pool, a biological filter pool, a microbe enrichment pool and a water pump. With the breeding method, Oxyeleotris marmoratus and hybrid Oxyeleotris are selected; the stocking size is 25 to 60 g; the stocking density is 50 to 80 fries per square meter; forage fishes and an artifical compound feed are poured for feeding; and the temperature of water in the breeding workshop is controlled to be 18 to 32 DEG C. The method provided by the invention has the advantages of simple equipment, low operation cost and strong operability; the external-circulation water system has prominent ecological characteristics and significant water-saving, ecological and breeding effects; and by controlling factors or links like baits, sewage treatment and water quality, marketable fishes with a weight of 50 kg or above can be bred in one cubic of water, and the survival rate of breeding is 90% or above.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for industrialized cultivation of fish, in particular to an ecological cultivation method for industrialized outer-circulating water of Channa cuspidatum. Background technique [0002] Oxyeleotris, commonly known as Marble goby, belongs to Percifomes, Gobioidei, and Eletridae in classification. Its meat is tender and delicious. It is delicious and has few thorns. It is a valuable edible fish. It is deeply loved by consumers in my country, Japan, Southeast Asia, Hong Kong, Macao and Taiwan, and has a large market prospect and development space. At present, my country’s pond culture has made great achievements. Only in the Pearl River Delta region, the annual breeding area reaches more than 8,000 mu, but the breeding technology is single, the survival rate of production and breeding is low, there are many diseases, and the safety of breeding is lack of control. Serious Af...
