Parent fish rearing method for gymnocypris potanini

Abstract

The invention discloses a parent fish rearing method for gymnocypris potanini. The method comprises the steps that A, standby parent fishes are selected, wherein fishes without surface wounds are selected as the standby parent fishes; B, the parent fishes are put, wherein the parent fishes are put in breeding buckets, and the breeding buckets are disinfected with potassium permanganate; C, temporary rearing is carried out, wherein wild standby parent fishes are put in the buckets and are not fed; D, eating training is carried out, wherein water earthworms and feed special for salmon and bulltrout are mixed to be uniform for eating training; E, breeding is carried out, wherein fishes fished in anestrous seasons are bred; F, the parent fishes are selected, wherein before the anestrous seasons, the developed parent fishes are selected for gonad reinforcement breeding, and feed, water flow and male and female mixed culture are included; G, artificial reproduction is carried out, wherein the parent fishes stops being fed before artificial reproduction is carried out, the parent fishes are fished out, and the female fishes developed well are selected for artificial reproduction. The method is easy to implement and easy and convenient to operate, the parent fishes which are mature, large in brood amount, high in reproduction capacity and high in sperm and egg quality are obtained, and synchronous development of the male parent fishes and the female parent fishes is achieved.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically relates to a broodstock culture method for artificial propagation of Songpan naked carp, which is suitable for breeding Songpan naked carp broodstock for breeding. The application of this method can obtain large number of eggs, strong fecundity and roe High-quality Songpan naked carp female parents can greatly increase the synchronous maturity rate of male and female parents. Background technique [0002] Songpan naked carp (Gymnocypris potanini) belongs to Cypriniformes, Cyprinidae, Naked carp, commonly known as forest leaves, cold water fish, cold water rods, etc. It is a specialized cold-water fish in plateau and mountainous areas and is a provincial-level protected fish in Sichuan Province. It is also an important cold-water economic fish unique to China. It is mainly distributed in areas such as the tributaries of the upper reaches of the Yangtze River, including the Mi...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no artificial breeding of Songpan naked carp. Most of them are fished by fishermen. During the breeding season, they select better-developed fish and inject them to induce labor. Artificial breeding is very unstable and is greatly restricted by natural conditions.
