Problems solved by technology

In view of this, it is imminent to carry out the work of artificial propagation and seed cultivation of Yarkand plateau loach. Although some scholars have carried out research work on artificial propagation, it has not been found so far that Yerkand plateau loach is cultivated from the late stage of embryonic development, that is, the larvae with ruptured membranes.

Embodiment Construction

[0026] A kind of cultivation method of Yarkand plateau loach 1-year-old fish of the present invention comprises the following processing steps:

[0027] 1 Materials and methods

[0028] 1.1 Materials

[0029] Experimental animals: Yarkand plateau loach ruptured larvae (1.30-1.97mm) artificially propagated in the aquatic base of Tarim University, temporarily kept in the aquarium for use in experiments;

[0030] Experimental materials: 60×30×40 (cm) glass aquarium; aeration pump (0.8-1kw); salt; potassium permanganate

[0031] There are two types of experimental feed:

[0032] Experimental feed 1, shrimp powder (Tianjin Yingwei Aquatic Products Co., Ltd.); flax oil; sheep oil; honey; water.

[0033] Experimental feed two, carp feed with a diameter of 1-1.5mm (Xinjiang Tiankang Feed Company); flax oil; starch; sheep oil; honey; water.

[0034] Experimental water: Tap water was aerated for 48 hours (pH=7.0-8.0; DO=7±2mg / L; temperature=19±2°C), pumped into the reservoir, and an...

Abstract

The invention provides a method of cultivating Triplophysa yarkandensis yearlings, wherein first experimental feed is applied from 1-week age to 2-month age, and second experimental feed is applied from 3-month age to one-year age; the first experimental feed is made by the steps of adding linseed oil, mutton fat, honey and water into shrimp meal, and stirring to obtain paste; the second experimental feed is made by the steps of adding carp feed into water, soaking until feed particles are softened enough for rolling, adding linseed oil, starch, mutton fat, honey and water, and stirring to obtain paste. In addition, different cultivation densities and control measures are taken based on feeding so that cultivation purposes are achieved. The method has the advantages that based on successful artificial reproduction, different cultivation methods and different feed ratios and stocking densities are used in connection with different disease preventive measures to study the growth of Triplophysa yarkandensis first-generation yearlings, and theoretical basis is provided for multiplication protection and seed production of Triplophysa yarkandensis.

Description

technical field [0001] The invention belongs to the technical field of artificial breeding, and in particular relates to a method for cultivating first-year-old loach in the Yarkand Plateau. Background technique [0002] Yarkand Plateau Triplophysa (Hedinichthys) yarkandensis (Day), place name: dog head fish, small big head, belongs to Cyprinidae, Loachidae, Strigoidae, Plateau Loach, Swimbladder subgenus, indigenous fish of the Tarim River system kind. Most of the research on the fishery of the Tarim River system focuses on the investigation of the fishery environment, exotic species, schizothorax and loach fish biology research; the research on the plateau loach in this water system is only the report of new species, morphological characteristics, feeding and growth etc., the reports on the Yarkand plateau loach are only a few research reports on biological characteristics, growth and feeding habits, and reproductive habits. [0003] In recent years, the resources of the...
