Problems solved by technology

[0003] In the process of artificial breeding, in order to overcome the shortcomings of low efficiency in the natural breeding process, low survival rate of fry, and high deformity rate, the use of artificial breeding technology is the most important link. However, in the existing artificial breeding technology of yellow catfish, there are broodstock The utilization efficiency is not high, the cost of artificial reproduction is high, and the survival rate of hatching is low, and these problems are more prominent in the process of artificial breeding of hybrid yellow catfish

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the embodiments, but it is not intended to limit the scope of the present invention, but only for illustration.

[0022] A method for mass breeding of hybrid yellow catfish, its concrete process is as follows:

[0023] (1) Broodstock selection

[0024] Yellow catfish (♀) comes from Hubei Jiaowan yellow catfish breeding farm (provincial level). After special breeding and screening, the adult fish is 5000kg, and the average weight of the tail is 100g. Jianghuang catfish (♂) came from adult fish collected in the natural waters of the Yangtze River and specially bred as broodstock. There were 100 fish in total, with an average weight of 750g. The yellow catfish has a strong body, no disease, no injury, and no deformity. It has round urinary pores and almond-shaped genital pores, and its abdomen expands when it is mature. Jianghuang catfish has a strong body, no disease, no injury, and no deformity. ...

Abstract

The invention provides a mass artificial propagation method of hybrid pelteobagrus fulvidraco. The requirements for high parent fish utilization ratio, high propagation success rate, high fry survivalrate and the like in an artificial propagation process are met by processes such as selection and aquaculture of parent fishes, daily management of parent fishes, artificial spawning induction, artificial insemination and incubation management, in addition, mass production can be realized, the problem of fry sources is solved, and the basis is laid for the large-scale artificial aquaculture of the hybrid pelteobagrus fulvidraco.

Description

technical field [0001] The invention belongs to the technical field of breeding and breeding, and in particular relates to a batch artificial breeding method for hybrid yellow catfish. Background technique [0002] Pelteobagrus fuvidraco (Richardson) belongs to Sliuriformes, Bagridae, and Peltebagrus. Pelteobagrus fuvidraco has become a popular fish in recent years because of its delicious meat, no intermuscular spines, and suitable size. One of the most popular high-quality food fish for people. With the change of market demand, the farming of yellow catfish has developed rapidly. Pseudobagrus vachelli (Richardson) is also called Pseudobagrus vachelli. It belongs to Sliuriformes, family Bagridae, and Pelteobagrus. It is the largest individual in the genus Pelteobagrus, and the individual is more than twice the size of the yellow catfish. Usually, the individual is about 250-750 grams , the largest individual up to 1850 grams. [0003] In the process of artificial breedi...
