Problems solved by technology

However, due to overfishing and water environment pollution, wild resources have been greatly damaged, and the number and species have declined sharply; the water storage in the Three Gorges Reservoir may also cause changes in the living environment of fish (feeding grounds, breeding grounds, etc.), which will affect the population. The reproduction of the fish poses a serious threat, so the protection of fish resources is imminent

Embodiment Construction

[0006] The key technology is to develop the artificial induced spawning and insemination techniques of Peltedelachus waschii. Through experiments to determine the timing of artificial induction of broodstock, as well as the optimal drug and dose of induction of labor under the condition of artificial breeding; develop the technology for the normal development of fertilized eggs obtained by artificial insemination.

[0007] 1. Obtain biological data about its growth and reproduction by combining field sampling and experimental observation. On this basis, the experimental conditions for artificial breeding of broodstock were designed. Through the continuous sampling and measurement of annual artificial breeding broodstock data, further optimize the breeding conditions and identify the sexual maturity of broodstock.

[0008] 2. In the large-scale recirculating aquaculture system that strictly controls environmental and ecological factors, the best oxytocic agent, the optimal oxy...

Abstract

The invention relates to an artificial reproducing and breeding technology of pelteobagrus vachelli. According to the research and the development for the artificial reproducing and breeding technology of the pelteobagrus vachelli which is high-quality wild commercial fishes, the pelteobagrus vachelli can be a new breeding breed. The artificial reproducing and breeding technology mainly comprises a domesticating technology for parent fish, a distinguishing technology for sexual maturity of the parent fish, an artificial spawning technology, an artificial inseminating technology, an embryo hatching technology and a larva fish breeding technology.

Description

【Technical field】 [0001] The present invention relates to artificial propagation and nursery technology of Pelteobagrus vachelli, especially the research on artificial propagation and fry cultivation technology of Pelteobagrus vachelli, and the development of high-quality breeding objects to meet the needs of Chongqing Municipality. The urgent needs of industrial development, and provide theoretical guidance for the artificial propagation and breeding techniques of other famous and high-quality cultured fish. 【Background technique】 [0002] There are abundant fish resources in the waters of the Yangtze River in Chongqing. However, due to overfishing and water environment pollution, wild resources have been greatly damaged, and the number and species have declined sharply; the water storage in the Three Gorges Reservoir may also cause changes in the living environment of fish (feeding grounds, breeding grounds, etc.), which will affect the population. The reproduction of the...
