Embodiment Construction

[0025] In the following text, the invention will now be described more fully, illustrating various embodiments. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0026] 1. Select mature broodstock

[0027] Choose mature broodstock, the male genital papillae are red, and a little white semen flows out when the abdomen is squeezed; the abdomen of the female fish is swollen, and the genital papillae are reddish. The selected broodstock will be grouped according to the male-to-female ratio of 1.5:1, and the mantissas will be counted and weighed respectively.

[0028] 2. Types and doses of oxytocin drugs

[0029] The dosage of female fish is: 25mg DOM / Kg body weight; the dosage of male fish is: 15mg DOM / Kg body weight. ...

Abstract

The invention relates to a spawning induction method of highland oxygymnocypris stewartii. The method comprises the following steps: selecting adult parent fishes; selecting type and dose of drugs for spawning induction; processing the drugs; determining the drug application method; performing artificial fertilization. According to the spawning induction method, the use of carp pituitary gland is reduced and even removed from the spawning induction drugs under the condition that the carp pituitary gland is difficult to obtain at Tibet region, the compatibility of proper spawning induction agents suitable for spawning induction of oxygymnocypris stewartii is developed, and batch artificial propagation of oxygymnocypris stewartii is successfully performed at high-altitude and alpine region in Tibet.

Description

technical field [0001] The invention relates to a method for inducing spawning of a plateau fish, the naked carp, and belongs to the field of fish breeding. Background technique [0002] Using artificial injection of exogenous hormones to make fish spawn is the main way to obtain fertilized eggs of fish. At present, most fish can obtain fertilized eggs through artificial induced spawning. [0003] The exogenous hormones used for fish artificial oxytocin include carp pituitary gland (PG), chorionic gonadotropin (HCG), luteinizing hormone-releasing hormone analog (LRH-A), luteinizing hormone-releasing hormone A3 , luteinizing hormone-releasing hormone A2, compound salmon gonadotropin-releasing hormone analogues, dioconone maleate (DOM), etc. [0004] In principle, the above hormones can be used to induce labor in fish, but specific to a fish, not every fish must use all of the above hormones at the same time. In specific practice, the compatibility of oxytocin hormones (hor...
