Embodiment Construction

[0019] The present invention will be further described below with embodiment.

[0020] A method for hybrid breeding of yellow catfish and Ussuri catfish, comprising the following steps:

[0021] 1. Parent selection and cultivation

[0022] In the autumn of 2007, select yellow catfish over 2 full years of age without disease and injury, male fish weighing more than 0.6 kg, and female fish weighing more than 0.3 kg, and yellow catfish over 2 full age without disease and injury, male fish weighing 0.25 kg or more. Ussuri catfish with a weight of more than 1 kg and a female weighing more than 0.1 kg are used as hybrid breeding parents. The ratio of male and female fish is 2:1, stocking 150-200 kg per mu, and the depth of the pond is 1.5 meters. During the breeding period, they are fed with compound feed and surimi , starting from the end of March, flush once every 10-15 days, each time for 1-2 hours, to promote the maturation of the gonads;

[0023] 2. Hybrid breeding

Abstract

The invention relates to a pelteobagrus vachelli and pseudobagrus ussuriensis cross breeding method, which is characterized by comprising the steps of parent selection and breeding, outbreeding, cross bred fingerling culture and the like. By the pelteobagrus vachelli and pseudobagrus ussuriensis cross breeding method, a crossbreed of pelteobagrus vachelli and pseudobagrus ussuriensis, which has rapid growth, strong disease resistance and excellent meat quality can be obtained; and the method has significance for improving specific yield, breeding benefit, and serving production practice.

Description

technical field [0001] The invention relates to a method for breeding edible fish, in particular to a method for crossbreeding fish, in particular to a method for crossbreeding of yellow catfish and Pseudomonas ussurii. Background technique [0002] Cross breeding is the most classic breeding method. Different types of parents can be crossed to obtain hybrid offspring with gene recombination and rich types. Some types may be a combination of excellent traits of both parents, and excellent traits of super-parents may also appear. In fishery, the use of heterosis has become an important way to increase fishery output. [0003] Pelteobagrus vachelli and Pserdobagrusussuriensis belong to the genus Pelteobagrus vachelli and Pserdobagrus suriensis respectively in the family Siluriformes, and are two species of fish in the same family but with different genera. These two species of fish are the main economic fishes of the family Oleopsis in my country. Because of their tender mea...
