Embodiment Construction

[0006] The breeding method of Channaidae fishes has the following steps: pool selection - parent fish breeding and cultivation - artificial induced spawning - spawning and fertilization - fish egg hatching - larvae cultivation, and fish eggs are fertilized during spawning and fertilization After hatching the small fish, fish out the parent fish. Generally, after selecting a broodstock breeding pond, such as a cement pond with an area of ​​1,000 square meters, first use quicklime to clear the pond for disinfection. Breeding and breeding of broodstock refers to the selection of stable genetic traits, strong physique, no disease and injury, a weight of more than 0.75kg, and an age of more than 2 years old. , the mature broodstock is a species, and the ratio of male to female is 1:1. In addition to the domination of the same species of snakeheads, fish with short growth periods and large individuals were selected as broodstock for hybridization. For example, choose 500 snakeheads...

Abstract

The present invention relates to an artificial breeding and pisciculture method of murrel, including the following steps: selecting piscicultural pond, breed selection of parent fish and cultivating,artifically-hastening parturition, spawning and fertilization, fish roe incubation and fish fry cultivation. In the course of spawning and fertilization, after the fertilized eggs are incubated and the fish fries are obtained, the parent fishes can be taken out. The health mature parent fish can be used as seed fish, and the ratio of male and famel is 1:1, and its propagation coefficient and percentage of success are high.

Description

technical field [0001] The invention relates to an artificial breeding and cultivation method of snakehead fishes. Background technique [0002] Channa is the general term for fish of the Channa family. Because of its habit of preying on other fish, it has always been regarded as a harmful fish in the aquaculture industry. But just because it is a carnivorous fish, it tastes good and is very nutritious. The meat contains a lot of protein, which is higher than that contained in chicken and beef, and it has fewer bone spurs and high meat content. It has medical significance. It has the effects of removing blood stasis and promoting regeneration, nourishing and recuperating, etc. Eating snakehead fish after surgery or trauma has the functions of promoting muscle growth, enriching blood, astringent, accelerating the growth of tender meat and granulation, and promoting wound healing. With the change of people's understanding of it, the demand has increased rapidly, but the natur...
