Embodiment Construction

[0026] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Present embodiment provides a kind of Lhasa Schizothorax artificial breeding method, comprises the steps:

[0028] (1) Preparation for breeding broodstock

[0029] The caught wild Lhasa Schizothorax is transported to the domestication pond, and water earthworms and salmon and trout fish feed (produced by Chengdu Gelan Company, the specifications are 0.5# and 0.8# salmon and trout fish feed, the protein content is 58%) Mix evenly for domestication, the daily feeding amount is 2 to 6% of the fish body weight, and feed twice a ...

Abstract

The invention provides an artificial breeding method of schizothorax waltoni. The artificial breeding method includes following steps: 1), domesticating wild schizothorax waltoni to obtain a reproduction parent fish; 2), injecting the reproduction parent fish with oxytocin composed of chorionic gonadotropin, luteinizing hormone-releasing hormone analogue and domperidone in two times for artificialspawning induction to obtain fertilized eggs; 3), adopting microflow water of 10-15 DEG C to artificially incubate the fertilized eggs to obtain schizothorax waltoni fries; 4), putting the schizothorax waltoni fries into a pond, and starting to feed food 10 days after the fries are hatched until the fries grow well to obtain schizothorax waltoni. Oxytocin is injected by means of injection in twotimes, injection dosage of each time is controlled strictly, well developed eggs and seminal fluid can be obtained, and fertilized egg incubating conditions are controlled, so that induced spawning rate of schizothorax waltoni is higher than 75%, fertilization rate is higher than 90%, hatching rate is higher than 85%, large-scale artificial breeding of schizothorax waltoni is realized, and the resource is protected effectively.

Description

technical field [0001] The invention belongs to the technical field of fish breeding, and in particular relates to a method for artificial breeding of Schizothorax Lhasa. Background technique [0002] Lhasa Schizothorax (Schizothorax waltoni Regan) belongs to Cypriniformes (Cypriniformes) Cyprinidae (Cyprinidae) Schizothoracinae (Schizothoracinae) Schizothorax Heckel (Schizothorax Heckel), alias Lhasa Bowfish, Belle Schizothorax, commonly known as pointed Mouthfish, distributed above the Yarlung Zangbo River Milin to the main and tributaries of Shigatse, is an endemic species in my country and one of the main economic fish in Tibet, which has important research value. [0003] In recent decades, with the rapid development of Tibet's economy and society, human beings have been increasingly exploiting and utilizing Tibet's fishery resources. The Yarlung Zangbo River Basin, where the population is concentrated, is undoubtedly subject to increasingly intense human activities, su...
