Problems solved by technology

However, due to overfishing and overfishing, foreign species devour their eggs in large quantities, causing extremely serious resource damage and are now on the verge of extinction. Artificial breeding of Schizothorax has become an inevitable
[0003] At present, there are only studies on the reproductive habits and breeding groups of Schizothorax in China. Only Cao Wenxuan et al. The report of Schizothorax intermedius abroad has Sunder et al. (1979, 1984, 1985) reports on several Indian Schizothorax and Ycmahba (1982) on Schizothorax intermedius. There are also relevant reports on the breeding population and breeding habits of Schizothorax produced in Sichuan. Reports, such as Chen Yongxiang, Luo Quansheng, Sichuan Schizothorax Reproductive Ecological Biology, Bijie Teachers College, 1997, the first issue, but due to the physiological habits of Schizothorax and the factors affecting the external natural environment, artificial reproduction is determined. The difficulty of Schizothorax, there is no report of artificial breeding of Schizothorax

Embodiment 1

[0017] Embodiment 1 Schizothorax artificial propagation method

[0018] Schizothorax artificial propagation method comprises five steps of broodstock source, broodstock cultivation, artificial insemination, hatching, fry cultivation, and is characterized in that:

[0019] a. Source of broodstock: wild seedlings caught in the Jinsha River and Yalong River in the southwest of Sichuan, and the Anning River in the central part of Liangshan Prefecture after 3 to 4 years of artificial domestication;

[0020] b. Breeding of broodstock: The environment is cultivated in a cold water environment with good water quality, high water flow velocity and gravel substrate. Conventional oxytocin drugs can be used for prenatal use;

[0021] c. Insemination: The water temperature is 14°C to 20°C, artificial insemination is used, and the fertilization rate can reach 90%;

[0022] d. Incubation: water temperature: 14°C-20°C, time: 4-10 days, and the hatching rate reaches 80%;

[0023] e. Fish fry...

Abstract

An artificial reproduction method for schizothorax includes choosing parents fish, culturing, fertilization, incubation and culturing fry.

Description

technical field [0001] The invention provides an artificial propagation method of Schizothorax, in particular to a method for artificial propagation of wild cold-water Schizothorax. Background technique [0002] Schizothorax is a rare and valuable economic fish. In my country, it is mainly distributed in the main and tributaries of the Yangtze River such as Qingyi River, Dadu River and Anning River, especially in canyon rivers of Jialing River, Minjiang River and Tuojiang River system. The meat of Schizothorax is tender, delicious and nutritious, and it is a high-end comprehensive food. At present, the market price of Schizothorax is 80-100 yuan / kg, which is more than 10 times that of traditional products. The market prospect is considerable, the economic benefits are rich, and the return on investment is high. However, due to overfishing and overfishing, foreign species devoured a large number of its eggs, causing extremely serious resource damage. It is now on the verge o...
