Problems solved by technology

[0005] 201811153137.5's invention "Giant Salamander Breeding Technology" informed a giant salamander breeding method, but there are essential differences between Yiwu small salamander and giant salamander in terms of habitat environment, water quality requirements, body size, bait type, growth temperature, and breeding period. Therefore, The above-mentioned farming methods for giant salamanders are not applicable to the farming of small salamanders in Yiwu

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 a method for artificially cultivating small salamanders in Yiwu, which comprises four parts: setting the farm environment, cultivating facilities, cultivating and feeding, and preventing and controlling diseases. The present invention selects breeding environment, designs cultivation facilities, cultivates and raises (including selection and cultivation of species salamanders, spawning, hatching of salamander eggs, cultivation of pheasant salamanders, cultivation of young salamanders until completion of metamorphosis, cultivation of adult salamanders, and feed cultivation and management, etc. ), disease prevention and control, by setting different breeding ponds, breeding densities, bait types and feeding amounts, controlling certain hatching conditions, and combining disease treatment methods at different developmental stages, a complete set of Yiwu small salamander breeding technology makes the hatching rate, survival rate of juvenile salamander, landing rate of young salamander and survival rate of adult salamander reach more than 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...
