Embodiment 1

[0014] A method for artificially inducing labor of wild Sichuan-Shaanxi salmon, the steps are:

[0015] (1) When the water temperature of the wild Sichuan-Shaanxi salmon growing waters is 6.5°C every year, select a male fish with a weight of 5 kg and a female fish with a weight of 7 kg under natural growth, and count and weigh the tails respectively;

[0016] (2) 5% glucose solution is used as a diluent for the drugs used, and they are diluted and mixed for use.

[0017] (3) Inject the oxytocin pharmaceutical composition at 0.4mL / kg at the lower 1 / 3 of the pectoral fin base of the female broodstock. After the injection, the female and male broodstock are raised in the pool at a ratio of 2:1, and stimulated by uninterrupted running water;

[0018] Wherein, the formulation of the oxytocin pharmaceutical composition is: salmon analogue 5ug / kg, chorionic gonadotropin 500IU / kg and dioconone domaleate 1ug / kg.

[0019] (4) Collect ova and semen from female and male fish respectively...

Embodiment 2

[0022] A method for artificially inducing labor of wild Sichuan-Shaanxi salmon, the steps are:

[0023] (1) When the water temperature of the wild Sichuan-Shaanxi salmon growing waters is 6.2°C every year, select a male fish with a weight of 4.5 kg and a female fish with a weight of 6.6 kg under natural growth, and count and weigh the tails respectively;

[0024] (2) 5% glucose solution is used as a diluent for the drugs used, and they are diluted and mixed for use.

[0025] (3) Inject the oxytocin pharmaceutical composition at 0.4mL / kg at the lower 1 / 3 of the base of the pectoral fin of the female broodstock. After the injection, the female and male broodstock are raised in the pool at a ratio of 3:1, and stimulated by uninterrupted running water;

[0026] Among them, the formulation of the oxytocin pharmaceutical composition is: salmon analogue 5ug / kg, chorionic gonadotropin 500IU / kg and dioconone maleate 1ug / kg, and in the process of drug preparation, 5% glucose is used as ...

Embodiment 3

[0030] A method for artificially inducing labor of wild Sichuan-Shaanxi salmon, the steps are:

[0031] (1) When the water temperature of the wild Sichuan-Shaanxi salmon growing waters is 7.5°C every year, select a male fish with a weight of 5.5 kg and a female fish with a weight of 7.5 kg under natural growth, and count and weigh the numbers respectively;

[0032] (2) 5% glucose solution is used as a diluent for the drugs used, and they are diluted and mixed for use.

[0033] (3) Inject the oxytocin pharmaceutical composition at 0.4mL / kg at the lower 1 / 3 of the base of the pectoral fin of the female broodstock. After the injection, the female and male broodstock are raised in the pool at a ratio of 3:1, and stimulated by uninterrupted running water;

[0034] Among them, the formulation of the oxytocin pharmaceutical composition is: salmon analogue 5ug / kg, chorionic gonadotropin 500IU / kg and dioconone maleate 1ug / kg, and in the process of drug preparation, 5% glucose is used a...

Abstract

The invention discloses a manual spawning induction method for wild hucho bleekeri. In each year, when the water temperature of a water region for growth of the wild hucho bleekeri is 6.2-7.5 DEG C, male fishes and female fishes in natural growth are selected, the number of the fishes is counted, and the fishes are weighed; a spawning induction medicine composition diluted with glucose is injected into the 1 / 3 position of the base portion of the pectoral fin of each female parent fish according to 0.4 mL / kg, and then the female fishes and the male fishes are bred in a pool according to the proportion of 2-3:1, and stimulated with running water constantly; after 10-11 hours of stimulation with the running water, egg collection and semen collection are carried out on the female fishes and male fishes, and after spawning induction, the male fishes and the female fishes are released into a natural water region. In the scheme, while fertilized eggs are obtained, the wild hucho bleekeri parent fishes for usage can be reasonably and effectively protected; the technical problem that at the present, it is difficult to obtain the fertilized eggs by training the wild hucho bleekeri, state first-grade protection animals can be protected better, and remarkable ecological benefits are achieved.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a method for artificially inducing spawning of wild Sichuan-Shaanxi Zheluo salmon. Background technique [0002] Chuanshan Zheluo salmon Huchobleekeri belongs to Salmonidae Salmonidae Huchobleekeri, which is a national first-class protected animal. It belongs to the large-scale salmonids unique to the upper reaches of the Yangtze River, and is also the only large-scale indigenous salmonids in the Qinghai-Tibet Plateau. It is a national first-class protected animal. Salmon is included in the list of priority protected species of Class I fish, second only to white sturgeon, Chinese sturgeon, and Dabry's sturgeon, and ranks fourth; "China Red Book of Endangered Animals" published in 1998 and "China Species Red List" published in 2004 ", Chuanshan Zheluo salmon are listed as endangered species. Chuanshan Zheluo salmon is the southernmost species among the 5 species of Zheluo salm...
