Problems solved by technology

[0006] The selected Lancang River Schizothorax domestication subjects were more or less injured, and four drugs were used for prevention and treatment, including penicillin, bromochlorhydrin, crystal trichlorfon and quicklime. Even so, the domestication survival rate was only 26.5%
In addition, choose high-protein live bait for domestication, the cost is high

Embodiment 1

[0038] A kind of domestication method of wild Lhasa Schizothorax, the steps are as follows:

[0039] 1) Collection of broodstock

[0040] From September to November every year, broodstock are collected by electric fishing, and wild Schizothorax is selected with a size of 0.25-1.85kg, with an average of 0.52kg; before entering the pool, the Schizothorax Lhasa is placed in a potassium permanganate solution with a concentration of 15ppm , soak for 15min;

[0041] 2) Temporary breeding of broodstock

[0042] Before entering the domestication pool, temporarily raise them in the temporary breeding pool, adopt the running water mode for temporary breeding, and build a shade shed at the same time, with a shade area of ​​1m 2 , the holding time is 3 days;

[0043] 3) Domestication of broodstock

[0044] Adopt flowing water for domestication, control the dissolved oxygen above 5.5mg / L, and fix the daily water exchange volume to one-third of the total water body; the first three days w...

Abstract

The invention provides a method for taming wild Lhasa Schizothorax. Parent fish is collected with an electric fishing method, the parent fish which is well-developed, vivacious and robust in health is selected as a taming object, potassium permanganate is used for disinfection, high protein dead bait and buoyancy pellet feed are selected and fed alternatively for taming, and the taming survival rate is higher. The taming method is simple, the operability is high, the piratical applicability is good, large-scale and standard taming of wild Lhasa Schizothorax can be realized, development of the Lhasa Schizothorax is promoted, and the wild wild Lhasa Schizothorax resource is effectively protected.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for domesticating wild Schizothorax Lhasa. Background technique [0002] Lhasa Schizothorax (Schizothorax waltoni Regan) belongs to Cypriniformes (Cypriniformes), Cyprinidae (Cyprinidae), Schizothoracinae (Schizothoracinae), Schizothorax, commonly known as sharp mouth fish, is an important indigenous economy in the Tibetan Plateau One of the fish, it is a cold-water fish, mainly distributed in the middle and upper reaches of the Yarlung Zangbo River, its tributaries and its affiliated water bodies. It is a unique species in my country. In nature, there are more females than males of Lhasa Schizothorax, which belongs to the type of synchronous batch spawning. Spawning occurs once a year, mainly from March to April. The breeding period is relatively short, and the average number of brood eggs is 19,000 grain. In recent years, with the rapid development of ...
