Embodiment Construction

[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0025] refer to figure 1 , the large-scale artificial propagation method of river sand pond snakehead, comprises the steps:

[0026] The first step is broodstock breeding: before seed production, feed the broodstock and carry out intensive breeding of the broodstock, with the purpose of strengthening nutrition, promoting gonad development, and increasing the amount of fecundity. The bait is fish fry and shrimp fry, and the feeding rate is 1%-3% of the broodstock body weight each time. When broodstock is cultivated, sufficient nutrition is given to the broodstock so that a high amount of fecundity can be obtained. The average amount of broodstock of the above-mentioned design is 5000 grains / tail.

[0027] The second step, spawning reproduction: the ...

Abstract

The invention relates to the technical field of fish artificial propagation, in particular to a large-scale artificial propagation method for odontobutis potamophila. The large-scale artificial propagation method for odontobutis potamophila includes the steps: 1) parent fish rearing: feeding baits to parent fish before fry production, and performing parent fish strengthening cultivation for intensifying nutrition, promoting gonad development and increasing brood amount; 2) egg reproduction: hanging spawning nests at a spawning pool; and 3) parent fish egg protection and incubation: putting spawning nests with fish eggs and male parent fish in an incubation pool for incubation. By means of the technical scheme, manpower and material resources can be saved, production steps can be simplified, production efficiency is improved, and fry requirement of large-scale aquaculture can be met.

Description

technical field [0001] The invention relates to the technical field of artificial breeding of fish, in particular to an artificial breeding method of Channa channa. Background technique [0002] Odontobutis potamophila has less thorns, a high proportion of edible parts, and high nutritional value. It has the reputation of "the first dish of the World Expo" in China. At present, the river snakeheads on the market still rely on natural waters for fishing, and the quantity is not large. In recent years, due to long-term ecological environment changes and other reasons, natural resources are increasingly depleted, and it is imperative to carry out artificial breeding and artificial breeding. However, the current reports show that there are many problems in the artificial propagation of Channa chinensis in rivers, such as small scale, less broodstock eggs, low hatching rate and emergence rate. Contents of the invention [0003] The object of the present invention is to provid...
