Problems solved by technology

If the fish species are caught from the wild, they are usually slow to domesticate, and due to the early injury, the physical decline is easy to cause saprolegniasis. If the control measures are not proper, the whole pond will die
Furthermore, it is best to catch all at once when catching, because Yayu likes to be clean and quiet, and is afraid of being disturbed. If it is caught, it will refuse to eat for several days, or even die, which will seriously affect its growth.

Abstract

The invention discloses an artificial reproduction method for schizothorax prenati. Individuals, preferably natural wild adult fishes which are 3-4 years old and are 0.5-1 kg in weight respectively are selected, and through the technical links of controlling the stocking density, water quality, temperature and bait, adopting estrus promotion for egg laying and insemination, breeding advanced fry and the like, a natural habitat environment of the schizothorax prenati is simulated in a breeding pond. According to the artificial reproduction method, the laying induction rate of female parent fishes reaches 85% or above, the fertilization rate is about 90%, the hatching rate reaches about 80%, and the method is superior to other reproduction methods for schizothorax prenati. The method has important significance on improving the effect of artificial reproduction of the schizothorax prenati.

Description

technical field [0001] The invention provides a method for artificial propagation of Schizothorax, in particular to a method for artificial propagation of wild cold-water Schizothorax. Background technique [0002] Schizothorax belongs to Cyprinidae, Cyprinidae, Schizothorax subfamily, Schizothorax genus, Schizothorax subgenus. Commonly known as: Yayu, Qikou, thin soft-shelled turtle, Qikou fine scale fish, which is a cold-water bottom fish. [0003] The meat of Qikou Schizothorax is plump, rich in unsaturated fatty acids, and delicious. It is a local specialty and is most popular among residents in the production area. Schizothorax's water temperature requirements are between those of warm-water fish and cold-water fish, and its living area is subject to certain restrictions. In recent years, due to water pollution and overfishing, the natural resources of Schizothorax have decreased sharply. [0004] Our country is rich in water resources, with many rivers and streams. ...
