Pond domestication technique for endemic wild triplophysa yarkandensis

Abstract

The invention relates to the technical field of aquaculture and discloses a pond domestication technique for endemic wild triplophysa yarkandensis. Larvae of wild triplophysa yarkandensis in the TarimRiver system are captured through spices and transferred to a culture base in a refrigerated manner, a pond with low temperature and high dissolved oxygen as a triplophysa yarkandensis habitat and without stress factors such as high light, noise and vibration is provided, aimed domestication of triplophysa yarkandensis is carried out, and growth indexes of triplophysa yarkandensis are determinedand analytically researched to provide theoretical basis for fry production of triplophysa yarkandensis and avoid extinction threatening caused by destroy and sharp reduction of resources in the triplophysa yarkandensis habitat. Therefore, the aquaculture success rate of triplophysa yarkandensis is increased while aquaculture efficiency is improved, and a key technical support is provided for population rejuvenation and multiplication protection of triplophysa yarkandensis and large-scale development and aquaculture in the future.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pond domestication technology for unique wild Yarkand plateau loach. Background technique [0002] Yarkand plateau loach, one of the largest and fastest-growing fishes in the family Loachidae, has a narrow lip, smooth lip surface or shallow wrinkles on the lower lip. Mandible spoon-shaped, barbels long, base of pelvic fin opposite to base of 1st branch of dorsal fin. The body surface is smooth without scales, the lateral line is complete, the anterior chamber of the swim bladder is enlarged, and the posterior chamber is degenerated. Intestine is short. The snout of males is triangular in shape with a raised area between the eyes and the posterior nostrils, which is covered with small spikes. Distributed in the Tarim River system in southern Xinjiang, my country. Bearded, scaleless, omnivorous fish, most of which are only as thick as fingers. Demersal fish inhabit deep ...

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the invention provides a pond domestication technology of a unique wild Yarkand plateau loach, which solves the domestication method of the Yarkand plateau loach that has no system, and the effect of domestication is relatively poor. The domestication success rate is low, and after the domestication is successful, the death rate is high, which has a great impact on the follow-up work, affects the protection work such as the artificial breeding of the Yarkand plateau loach, and restricts the large-scale promotion, development and breeding work.
