Method for breeding andrias davidianus

Abstract

The invention discloses a method for breeding andrias davidianus. The method for breeding the andrias davidianus comprises the following breeding and culturing steps of (1), constructing a mountain stream type imitated ecological breeding pool, sequentially arranging a plurality of raising units, which are connected with one another, from higher parts to lower parts along the flow direction of a water current in the imitated ecological breeding pool, wherein a communicating port is arranged between two adjacent raising units; slight grades through which the young andrias davidianus passes are arranged at the communicating ports; at least two caves used for shielding and hiding the young andrias davidianus are arranged in each raising unit; the communicating ports are also provided with barriers used for stopping the andrias davidianus from passing through; (2), selecting the young andrias davidianus; (3), putting the young andrias davidianus into the pool; (4), feeding the young andrias davidianus with food; (5), regulating and controlling water quality; (6), artificially inducing the young andrias davidianus. The artificial breeding is carried out on the young andrias davidianus by adopting the method for breeding the andrias davidianus, which is provided by the invention; the method for breeding the andrias davidianus has the characteristics that the spawning is rich; the fertilization is good; the hatching rate is high.

Description

technical field [0001] The present invention relates to a kind of animal breeding method, more specifically, relate to a kind of giant salamander breeding method. Background technique [0002] Giant salamander, also known as giant salamander, Latin scientific name: Andrias davidianus, is the largest and most precious amphibian in the world. It belongs to the national second-class protected amphibian wild animal. It is a key development of agricultural industrialization and characteristic agriculture and a species of wild animal genetic protection. The Chinese giant salamander is mainly produced in the mountain streams of the Yangtze River, the Yellow River and the upper and middle tributaries of the Pearl River. Due to the deterioration of the natural ecological environment, the natural reproduction rate of giant salamanders is getting lower and lower. Therefore, artificial breeding of giant salamanders is an effective means to protect and utilize this unique species. Giant...

AI Technical Summary

Problems solved by technology

Giant salamanders have extremely high requirements for the growth environment, especially for water temperature, water quality and breeding environment, and artificial reproduction is more difficult.
