Embodiment Construction

[0024] The artificially hatched fry of the wild Xiuli plateau loach from Heilongtan, Heqing County, Yunnan Province was selected for seed cultivation.

[0025] The seed cultivation method of the beautiful plateau loach of the present invention, its concrete steps are as follows:

[0026] 1.1 Temporary rearing of filmed larvae

[0027] The filmed larvae need to be raised temporarily to make them pass from the endogenous nutritional state to the exogenous nutritional state. Select the radius of 0.4m to be 1.0m high opening fry tank as hatching and temporarily raise pond, a PVC food grade water pipe is installed above the temporarily raise pond, water supply to larvae, sand head is installed, and oxygen is supplied to larvae with air compressor. The density of cultured fish fry is 0.3-0.4 million fish / m3; the water temperature is 16°C-18°C, the daily temperature difference does not exceed 2.0°C, the holding pond is kept in micro-flow water, the water level is 0.3m or 0.4m or 0.5...

Abstract

The invention relates to a seedling breeding method of Triplophysa venusta Zhu et Cao, which belongs to the technical field of fish breeding. The seedling cultivation method of Xiuli plateau loach includes: the temporary management of filmed larvae, the cultivation of open-mouthed fry, the artificial feeding of fry, the daily management in the middle and later stages, and the steps of fish disease prevention and control. The present invention has the advantages of: 1. Artificially bred rotifers are used as opening bait in the early stage of fish fry cultivation, which solves the contradiction that the beautiful plateau loach needs clean water and abundant natural bait to overcome the difficulty of opening the mouth. 2. The survival rate of fry is high, the growth is fast, the method is simple, easy to popularize, and the breeding cost is low. 3. It can effectively protect, develop and utilize the germplasm resources of Xiuli plateau loach.

Description

Technical field: [0001] The invention relates to a seedling breeding method of Triplophysa venusta Zhu et Cao, which belongs to the technical field of fish breeding. Background technique: [0002] Xiuli plateau loach (Triplophysa venusta Zhu et Cao) belongs to Cyprinidae, Loachidae, and plateau loach.
