Culture and artificial propagation method of Schizothorax eurystomus kessler

Abstract

The invention provides a culture and artificial propagation method of Schizothorax eurystomus kessler, and belongs to the technical field of freshwater fish propagation and the field of freshwater fish culture. The method comprises 12 technical key points of parent fish culture pond construction requirements, fry culture pond construction requirements, wild parent fish catching and domestication,parent fish intensive culture, mature parent fish selection, oxytocic preparation and injection, oxytocic process management, artificial spawn extrusion and insemination, spawn incubation and incubation management, fry culture, juvenile fish culture and juvenile fish culture. According to the breeding and artificial propagation method, the pond is convenient and practical, wild parent fishes are rarely injured, the maturity rate of the parent fishes is high, the brood amount is large, the maturity time is controllable, the egg squeezing time point is accurately grasped, the yield is stable, the fertilization rate, the hatching rate and the survival rate are high, the quality of eggs and fries is reliable, and the whole artificial propagation technical process is systematic and comprehensive.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating and artificially propagating Schizothorax. Background technique [0002] Wide-mouth Schizothorax (Schizothorax eurystomus kessler) belongs to Cyprinidae, Cyprinidae, Schizothorax subfamily, Schizothorax genus, also known as wide-mouth hip scale fish, wide-mouth bow fish, white striped fish, and cold-water fish. Domestically, it is mainly distributed in the Aksu River, Weigan River, Yarkand River, Kashgar River and their tributaries in Xinjiang. It is distributed in the Amu Darya River System and the Syr Darya River System in foreign countries. The distribution of sea wave elevation is 500m-3000m. fish. At present, due to factors such as overfishing, river drying up, development of hydroelectric cascades, and river construction, the amount of wild resources has declined sharply. The Xinjiang District Government has listed it as a Class II ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are very few research materials on Schizothorax, and there are no detailed reports on cultivation and artificial reproduction technology. There are only a few fish breeding and release stations or bases in Xinjiang for breeding and research, and there is a lack of complete and systematic technology in general. material
