Cultivation method for hybridized goldfish

Abstract

The invention discloses a cultivation method for a hybridized goldfish. The cultivation method comprises the following steps: S1, taking bred red-eye white butterfly-type tail goldfishes as female parents and taking bred green long-tail ryukin goldfishes as male parents; hybridizing the two types of the goldfishes to obtain a first-filial generation F1; S2, selecting five-color butterfly-type tail ryukin goldfishes and ink-color butterfly-type tail ryukin goldfishes to be hybridized to obtain a second-filial generation F2; S3, selecting female and male three-color butterfly-type tail ryukin goldfishes from the second-filial generation F2, and carrying out self-hybridization on the female and male three-color butterfly-type tail ryukin goldfishes to obtain three-color butterfly-type tail ryukin goldfish breeds capable of stably inheriting three-color butterfly-type tail ryukin properties. According to the cultivation method, the selection and the hybridization of the goldfish breeds are carried out to cultivate the new goldfish breeds, so that the variety of the goldfishes is enriched.
