Embodiment 1

[0042] On October 10, 2016, 527 female and 213 male giant barbats were selected to form the basic population to carry out experiments on the construction of giant barbat families and the selection of excellent families.

[0043] The technical scheme that the present embodiment takes according to the method for the construction of the giant barb family of the present invention and the selection and breeding of the excellent family is as follows:

[0044] A method for constructing a giant barb family and selecting an excellent family, specifically comprising the following steps:

[0045] (1) Selection and marking of parents

[0046] (1) Parental selection

[0047] On October 10, 2016, among the 527 female and 213 male giant barbs artificially bred, body mass was used as the main reference index to select healthy, non-trauma-free, complete scales, good color, and vitality. 5-year-old females with strong and mature gonads (egg production ≥ 20,000 eggs in May 2016) and males (with ...

Abstract

The invention relates to a family construction and excellent family breeding method for barbus capito. The method comprises steps as follows: (1), selection and marking of a parent; (2), strengtheningrearing of the parent; (3), induced spawning and incubation of parent fish; (4), fry rearing; (5), later culture of the family. The method has clear technical route, clear target and high operabilityand universality, by means of selection and marking of the parent in step (1) and induced spawning and incubation of the parent fish in step (3), family construction and breeding based on directionalmating are realized, a foundation is laid for developing the large-scale family breeding of the barbus capito, and a new line with excellent growth traits such as fast growth and the like is bred.

Description

technical field [0001] The invention relates to the technical field of breeding of fine fish varieties, and specifically designs a method for establishing and breeding a family of large scale barb fish. Background technique [0002] Barbus capito belongs to family Cyprinidae, subfamily Barbinae, and genus Barbodes. It is mainly distributed in the southern part of the Caspian Sea and the Aral Sea system, and inland rivers such as Uzbekistan, Iran, and Turkey. Anadromous fish is a local endangered and valuable large-scale economic fish. Large barb has excellent characteristics such as miscellaneous feeding habits, delicious meat, fast growth, strong stress resistance, and salt-alkali tolerance. In 2003, it was introduced from Uzbekistan to China (50 wild individuals), and from 2009 to 2018, it was promoted to more than 20 provinces and cities including Heilongjiang, Hebei, Tianjin, Beijing, Chongqing, Shandong, and Jiangsu. Due to the small size of the introduced population,...
