Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the examples. The feed used in the embodiment is all market purchases.

[0018] Since 2010, the research on artificial breeding of Schizothorax grayus has been carried out at the Gongguoqiao Fish Breeding Station and Huangdeng Fish Breeding Station in Lancang River, Yunnan Province. After 5 years of hard work, in March 2015, the artificial breeding of Schizothorax gray was successfully obtained at the Huangdeng Fish Breeding Station. The specific implementation method steps are as follows:

[0019] a. Harvesting and domestication of broodstock: Soak the broodstock captured from natural water bodies in the wild by means of nets and electric catches with 2% NaCl solution for 3 minutes, and put them into a room with a diameter of 3m, a water depth of 1m, and a water temperature of 10°C or 16°C Or 23 ℃, dissolved oxygen 4mg / L or 6mg / L or 8mg / L, pH value 7.8 or 8.8 domestication in the circ...

Abstract

The invention provides a manual schizothorax griseus pellegrin breeding method and belongs to the technical field of wild fish domestication and breeding, freshwater aquaculture and fish genetics-breeding. The manual schizothorax griseus pellegrin breeding method includes the following steps that 1, parent fish are caught and domesticated; 2, cultivation and spawning induction are conducted on the parent fish; 3, artificial insemination and egg hatching are conducted; 4, fry rearing is conducted. The manual schizothorax griseus pellegrin breeding method has the advantages that no report on the manual schizothorax griseus pellegrin breeding method exists in documents disclosed both home and abroad; the breeding method is scientific and reasonable, the rate of fertilization and the hatching rate of fries are higher and reach 98.6% and 91.2% respectively; the problem that no fry and fingerling exist for wild schizothorax griseus pellegrin resources is solved through manual recovery and supplement; the problem that no fry is supplied in the manual schizothorax griseus pellegrin breeding process is solved.

Description

Technical field: [0001] The invention relates to an artificial breeding method of Schizothorax griseus Pellegrin, which belongs to the technical fields of domestication and breeding of wild fish, freshwater culture and fish genetic breeding. Background technique: [0002] Schizothorax griseus Pellegrin (place name: face fish, fine scale fish), belongs to Cypriniformes Cypriniformes in classification, Cyprinidae Cyprinidae, Schizothoracinae Schizothoracinae, Schizothorax genus Schizothorax, distributed in the Yangtze River (Wujiang River), the Pearl River (Nanpan River), Lancang River, Irrawaddy River (Longchuan River, Daying River) water system.
