Embodiment 1

[0075] Embodiment 1, the artificial culture method of small salamander in Yiwu, including these four parts of setting farm environment, breeding facilities, cultivating and raising, and disease prevention and control.

[0076] details as follows:

[0077] 1. Selection of breeding environment

[0078] The breeding farm is located in a quiet, cool and humid hilly area, surrounded by lush trees, canopy density ≥ 50%, less human activities, and an independent environment as much as possible. Since the Yiwu small salamander does not have high requirements for water quality, ordinary Tap water can be used after 24 hours of aeration; that is, the water without specific requirements for dissolved oxygen in the following breeding process is tap water after 24 hours of above aeration.

[0079] 2. Design of breeding facilities (cultivation facilities)

[0080] The breeding facility includes a breeding pond and a water storage tank connected to the water inlet of each breeding pond;

Abstract

The invention discloses an artificial breeding method for Hynobius yiwuensis. The method includes: setting a farm environment, designing cultivation facilities, cultivating and controlling diseases. The method has the advantages that by designing four steps including cultivation environment selection, cultivation facility design, cultivation (comprising seed Hynobius yiwuensis selection and cultivation, spawning, Hynobius yiwuensis egg incubation, young Hynobius yiwuensis cultivation until transformation, adult Hynobius yiwuensis cultivation, feed cultivation, management and the like) and disease control, setting different cultivation ponds, cultivation density, bait varieties and feeding quantity, controlling certain incubation conditions and adopting different disease treatment manners in different growth stages, the complete Hynobius yiwuensis cultivation technology is obtained, and hatching rate, young Hynobius yiwuensis survival rate, young Hynobius yiwuensis landing rate and adult Hynobius yiwuensis survival rate of the Hynobius yiwuensis reach above 90%.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a method for artificial breeding of small salamanders in Yiwu. Background technique [0002] Yiwu small salamander (Hynobius yiwuensis) belongs to the class Amphibians, Cauraceae, Hynobius yiwuensis, and Hynobius genus. It is a rare amphibian in China, and it is only distributed in a few areas in Zhejiang such as Zhenhai, Yiwu, and Wenling. Yiwu small salamanders mainly live in hills and mountains at an altitude of 100m to 300m. Except for the breeding season, they live terrestrially. They are mostly found under loose and moist soil, stones or dead branches and rotten leaves. Mainly arthropods. Its sexual maturity is 2 years old, and the breeding season is from mid-November to February of the next year. It is an egg-laying type once a year. The female salamander lays a pair of egg plastic bags each time. However, there are differences, the average number of fertili...
