Embodiment Construction

[0027] 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.

[0028] Exogenous oxytocin drugs are used to promote the further development, spawning and fertilization of the gonads of the naturally mature Schizothorax broodstock to obtain fertilized eggs.

[0029] 1. Select mature broodstock

[0030] 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 cou...

Abstract

The invention relates to a parturition hastening method for plateau-fish schizothorax oconnori. According to the method, exogenous parturition hastening medicine is adopted to promote the parent fish gonad of the naturally-matured schizothorax oconnori to further develop, lay eggs and be fertilized to obtain fertilized eggs. The method comprises the steps of firstly, selecting matured parent fish, secondly, selecting the kind and dosage of the parturition hastening medicine, thirdly, conducting medicine treatment, fourthly, selecting a dosage method, and fifthly, conducting artificial insemination. According the dry method of artificial insemination, the carp pituitary gland is not used in the parturition hastening medicine, the compatibility of medicines of the suitable spawning agent suitable for parturition hastening of the schizothorax oconnori is found, and the batched artificial propagation is successfully carried out on the schizothorax oconnori at the high-altitude and alpine region in Tibet.

Description

technical field [0001] The invention relates to a method for inducing labor of plateau fish Schizothorax heterodontum, belonging to the field of fish reproduction. 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 analogue (LRH-A), luteinizing hormone-releasing hormone-A 3 , Luteinizing hormone releasing hormone A 2 , compound salmon gonadotropin-releasing hormone analogs, 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 ho...
