Artificial hybrid perch and breeding method thereof

Abstract

The invention relates to an artificial hybrid perch and a breeding method thereof. The breeding method comprises the steps that first parent selection, parent cultivation and artificial hybridization are carried out; the first parent selection comprises selection of a first female parent and selection of a first male parent; the parent breeding comprises the step of correspondingly breeding the first female parent and the first male parent to obtain a second female parent and a second male parent; the artificial hybridization refers to artificial hybridization of the second female parent and the second male parent; female Taiwan perch is used as a first female parent; and male micropterus salmonides obtained after second-generation breeding and screening are carried out by adopting group breeding and taking body weight as a main breeding target is used as a first male parent. According to the artificial hybrid perch and the breeding method thereof, the female Taiwan perches and the male superior perches are hybridized for the first time to obtain the artificial hybridized perches, and the hybridized perches grow fast, are high in survival rate and easy to domesticate after being industrially cultivated for one month and can serve as a novel high-quality variety in the micropterus salmoides industry.

Description

technical field [0001] The invention relates to the technical field of hybrid perch, in particular to an artificial hybrid perch and a breeding method thereof. Background technique [0002] Largemouth bass (Micopterus salmoides), also known as California perch, belongs to the perciformes sunfish family, and is a large carnivorous fish native to freshwater lakes and rivers in North America. At present, there are new varieties of California perch, such as "California perch No. 1" and "California perch No. 3", but after many years of breeding, these new species have problems such as mixed pollution of germplasm resources and unobvious growth advantages. Moreover, although the production of perch in California has increased year by year, the survival rate has decreased year by year after entering the pond. Among them, the key factor affecting the survival rate of California perch is the low domestication rate. [0003] At present, the main problems in the breeding technology o...

AI Technical Summary

Problems solved by technology

At present, there are new varieties of California perch, such as "California perch No. 1" and "California perch No. 3", but after many years of breeding, these new species have problems such as mixed pollution of germplasm resources and unobvious growth advantages.

Moreover, although the production of California perch rose year by year, the survival rate decreased year by year after entering the pond

Among them, the key factor affecting the survival rate of California perch is the low domestication rate

[0003] At present, the main problems of the California perch breeding technology are that it is impossible to artificially induce spawning in the same batch, the survival rate of the water flower domestication process is low, and the individual differences in eating and drinking are large and the growth rate is uneven.
