Embodiment Construction

[0009] The present invention will be further described below in conjunction with embodiment.

[0010] A method for collecting, domesticating and artificially breeding the original species of the Junggar crocodile, said method is completed by the following steps:

[0011] Original species collection: The original species of Junggar Yaluo fish is collected in Jinghe County, Boertala Mongolian Autonomous Prefecture, Xinjiang. Lake Aibi Wetland National Nature Reserve, the entire harvesting area is located in the wind channel area of ​​Alashankou; the harvesting tools mainly include cages, nets and purse seines. The work efficiency of ground cage harvesting is low and the loss of fish body is large, and the transportation and temporary breeding die one after another. Netting in the estuary is good for harvesting, but the casualties are too great. The seine net (mesh size 1cm×1cm, length, width and height 30m×3m×2m) is easy to operate, has a large harvesting capacity, and the sur...

Abstract

The invention belongs to the fishing industry, and relates to a protospecies harvesting, domesticating and artificial propagation method of leuciscus merzbacheri. The method comprises the following steps: protospecies harvesting, long-distance and short-distance transportation, protospecies harvesting temporary culture, protospecies disinfection, domesticating, parent intermittent rapid running water stimulation method, male and female identification, parent fish prenatal intensified cultivation, artificial spawning induction, artificial egg collection and fertilization and artificial incubation. The method has the characteristics that water is effectively saved, large-scale artificial breeding is facilitated, the death rate is effectively reduced, the hatching rate is increased, and the induced spawning rate can reach 90% or above.

Description

technical field [0001] The invention belongs to the fishing industry and relates to a method for collecting, domesticating and artificially breeding the original species of the Junggar crocodile. Background technique [0002] Junggar Yaluo fish (also known as Xinjiang Yaluo fish) is a fish of the genus Yaluo fish in the subfamily of Cyprinidae Yaluo fish. At present, it is only distributed in the Junggar Basin in Xinjiang, China. It is distributed in the estuary area of ​​Kuitun River into Lake Aibi. It is a landmark species in this area and a unique indigenous fish in Xinjiang. It is the only fish with high economic value among the rivers in the Junggar Basin. The key species (keyspecies) or flagship species (flagshipspecies) of aquatic organisms. [0003] There are three species of Yaluo in Xinjiang: Junggar Yaluo, Baikal Yaluo and Gaoti Yaluo. In terms of world geographical division, the Junggar Yaluo is a unique fish in Xinjiang. Chinese scholar Li Sizhong believes tha...
