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

Abstract

The invention provides a method for cultivating and artificially propagating Schizothorax broadmouth, belonging to the field of freshwater fish breeding technology and the field of freshwater fish cultivation, including the requirements for the construction of broodstock breeding ponds, the requirements for the construction of fish fry cultivation ponds, wild broodstock harvesting and domestication, There are 12 technical key points including intensive breeding of broodstock, selection of mature broodstock, preparation and injection of oxytocic agent, management of oxytocin process, artificial egg squeezing and insemination, hatching of fish eggs and hatching management, larval fish cultivation, juvenile fish cultivation, and juvenile fish cultivation. The cultivation and artificial propagation method involved in the present invention is convenient and practical in ponds, with less injury to wild broodstock, high maturation rate of broodstock and large amount of broodstock, controllable maturation time, accurate timing of egg squeezing, stable yield, high fertilization rate, hatching rate and The survival rate is high, the quality of eggs and seedlings is reliable, and the whole process of artificial propagation technology 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] Schizothorax eurystomus kessler belongs to Cyprinidae, Cyprinidae, Schizothorax subfamily, and Schizothorax genus. 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 the influence of factors such as overfishing, drying up of rivers, development of hydroelectric cascades, and construction of rivers, the amount of wild resources has decreased sharply. [0003] At present, there are very few research materials on Schizothorax, and there are no detailed reports on cultivation and artificial reproduction techno...
