A method for imitating ecological reproduction and healthy and efficient breeding of snakeheads

Abstract

The invention relates to the technical field of special aquaculture, in particular to a method for imitating ecological reproduction and healthy and efficient breeding of snakeheads. Including breeding mud ditch construction, breeding mud pond construction, moon snakehead imitation ecological breeding and healthy and efficient breeding. The breeding process is: selection and cultivation of fish before March of the first year - natural pairing of fish breeding into production from April to August of the first year Spawning in mud ponds for egg cultivation - hatching and seed cultivation of fish eggs from May to September of the first year - seedlings are graded and put into breeding mud ponds for cultivation from June to October - adult fish start to market in January of the second year . From the structure of the Channa aquaculture facility, the adjustment of the culture water quality, the species of culture bait, the drugs for disease prevention and disinfection to the whole process of cultivation, it is basically in the state of ecological reproduction and healthy and efficient cultivation. The product quality is similar to that of the wild, especially suitable for industrialization. Demonstration piles wide.

Description

technical field [0001] The invention relates to the technical field of special aquaculture, in particular to a method for imitating ecological reproduction and healthy and efficient breeding of snakeheads. Background technique [0002] Moon snakehead [channa asiatica (Linnaeus)], commonly known as star fish, point star fish, Qixingzi, mountain flower fish and so on. Perciformes, Channaidae. It is mainly produced in China, distributed in Hunan, Fujian, Jiangxi, Guangdong, Guangxi, Yunnan and other places south of the Yangtze River, and also distributed in northern Vietnam. Under natural conditions, the moon snakehead likes mountain streams, lakes, ponds, and even paddy fields and wetlands. It feeds on fish, shrimp, and aquatic insects. It is a carnivorous omnivorous fish. It likes to drill holes and live in groups, is good at jumping, pairs to lay eggs, and has the habit of exclusivity and mutual cannibalism. Moon snakehead is rich in nutrients and delicious in taste. It h...

Problems solved by technology

The existing traditional breeding methods mainly have the following disadvantages: (1) There is no vegetation and caves that imitate the natural ecological environment, and the conditions for the hidden environment and hidden cave dwelling of the snakehead are not provided, which leads to the disease and escape of the snakehead; (2) There is no Fully grasp the pairing technology of the channa, it is difficult to distinguish between the male and female of the channa, and the manual forced pairing leads to a success rate of less than 40%; (3) The territorial characteristics of the breeding of the channa are not fully considered, causing the channa to compete for production. The ovaries were bitten and injured; (4) The water quality pollution and disease prevention of the high-density culture of the moon snakehead were not fully considered, and chemical agents were used to improve water quality and treat diseases, resulting in environmental pollution and drug residues, and the survival rate of commercial fish could not reach 60%

(5) The wild growth characteristics of the snakehead are not fully grasped, the construction of the breeding facilities is too complicated, the operation is inconvenient, and the breeding cost is high
