Abstract

The invention relates to an artificial reproduction method for schizothorax wangchiachii. The method mainly comprises the following seven steps: bait preparation, parent fish sourcing, parent fish domestication, parent fish selection, artificial insemination, fish egg incubation and fish fry feeding. The artificial reproduction method for schizothorax wangchiachii has the beneficial effects that oxytocin is not used, the schizothorax wangchiachii can lay eggs and produce sperms, and relatively high fertility rate and hatchability can be obtained; the problem that female and male wild fish do not develop or develop asynchronously in a pond culture environment is solved fundamentally; the damage on the parent fish of the schizothorax wangchiachii is reduced, and the cultivation cost is also reduced; the method is reasonable and efficient, the hatchability is improved, and the waste of fish egg resources is reduced; and the aberration rate of the fish fry is reduced while the survival rate of the fish fry is improved.

Description

technical field [0001] The invention relates to a method for cultivating and artificially breeding Schizothorax broodstock and belongs to the technical field of artificial breeding of freshwater fish. Background technique [0002] Schizothorax wangchiachii belongs to Cypriniforms Cypriniformes, Cyprinidae Cyprinidae, Schizothoracinae subfamily Schizothoracinae, and Schizothorax genus Schizothorax. Inhabits the canyon section of the river in the plateau area, feeds on algae, and often lives in clusters. It belongs to the small and medium-sized cold-water economic fish of the Jinsha River system. Because of its tender meat, delicious taste and rich nutrition, it is very popular among consumers. [0003] In recent years, due to the destruction of the habitat and the frequent use of various unreasonable fishing methods, the existing resources of Schizothorax have been greatly reduced, making the market price increasingly expensive. The extremely high market value and the scarc...
