Embodiment

[0031] A method for selecting and breeding multiple colored two-tailed goldfish by distant hybridization, comprising the steps of:

[0032] (1) Selection and cultivation of broodstock: select strong growth, brightly colored female koi and high, silver-gray bream for artificial induction, artificial dry insemination, and running water hatching; the conditions for artificial induction are: : Female koi are injected with luteinizing hormone releasing hormone A25ug / kg, chorionic gonadotropin 1000 units / kg, domperidone 2mg / kg; male bream are injected with luteinizing hormone releasing hormone A23ug / kg, chorionic gonadotropin Hormone 600 units / kg; how to use artificial dry insemination, and then hatch in flowing water (temperature 22-24 ℃) to cultivate hybrid offspring;

[0033] (2) Selection and cultivation of Hunan army brocade crucian carp: At the end of December of that year, fishing was carried out with nets, and the high-back Hunan army brocade carp with obvious sexual maturit...

Abstract

The invention discloses a method for breeding a variety of colored two-tailed goldfish through distant hybridization. The Hunan Army crucian carp was obtained, and the male and female Hunan Army crucian carp were selected for cultivation in special ponds. Artificial induced labor, artificial dry insemination, and running water incubation were carried out until the self-bred offspring of the male and female Hunan Army crucian carp were pointing to the waist, and the yolk disappeared. Artificial intensive breeding, from which the homodiploid Hunan army goldfish with red pattern on white background, double tail forked, and high back was screened out. Strong reverse ability, strong fecundity and other advantages. Then hybridize Xiangjun goldfish with other goldfish in nature to breed a variety of beautiful double-tailed goldfish with different colors and colors. These double-tailed goldfish have obvious hybrid advantages and have very high sperm production and egg production It plays a very important role in the improvement of other goldfish.

Description

technical field [0001] The invention belongs to the technical field of fish hybridization, and in particular relates to a method for breeding multiple colored double-tailed goldfishes through distant hybridization. Background technique [0002] Distant hybridization refers to the hybridization between species, genera and even biological types with more distant kinship. Outcrossing can transfer genomes from one species to another, resulting in both phenotypic and genotypic changes in hybrid offspring. Distant hybridization can integrate the advantages of both parents, so that the hybrid offspring will show hybrid advantages in terms of appearance, growth speed, survival rate and disease resistance. [0003] As a beautiful ornamental fish, goldfish is deeply loved by people because of its bright and eye-catching colors. At the same time, the breeding and viewing of goldfish has added luster and fun to people's lives. With the rapid development of aquatic technology and goldf...
