Problems solved by technology

[0003] Due to the high ornamental value and edible value of salamanders, the demand for salamanders in the market is particularly large. People began to study large-scale artificial breeding of salamanders. When artificially breeding salamanders, many methods were used to artificially breed salamanders. However, the hatchability and survival rate are still not high

Embodiment 1

[0023] A kind of artificial reproduction method of salamander, comprises the following steps successively:

[0024] (1) Selection of breeding fish: The breeding fish used for artificial induction must be a sexually mature individual, with a healthy body and no injury, a swollen and soft abdomen, and a female fish whose abdomen feels full and soft when touched with hands. Has matured and can be used for artificial induced labor;

[0025] (2) Artificial oxytocin: put the species of fish into a dimly lit arched pool with a water depth of 35 cm, and lay washed pebbles on the bottom of the pool, the water quality is clean and transparent; the oxytocin hormones are chorionic gonadotropin (HCG) and luteinizing hormone Hormone-releasing hormone analogs (LRH~A for short); the dosage is 30mg / kg for HCG and 32mg / kg for LRH~A; the two hormones can be mixed; Insert the needle between the rib grooves on the back side, and the depth of the needle should be inserted through the muscle layer;...

Abstract

Provided is a method for artificial propagation of giant salamanders. The method includes the following steps of: (1) selection of fish species; (2) artificial inducement for spawning; (3) artificialegg supporting and fertilization: after semen is squeezed, the squeezed semen is diluted with 3-5 ml of diluent, the diluted semen is mixed with chalaza, sperm-egg binding is achieved through gentle shaking, a small amount of clear water is added after 5-10 minutes, water is changed twice after 30 minutes, and incubation is performed after the obtained mixture is divided into different basins; (4)artificial incubation and management; (5) juvenile fish feeding; and (6) growth of the giant salamanders. The method has the advantages of short fertilization time, a large amount of bound sperms andeggs, a high hatching rate, short propagation time and a high survival rate.

Description

technical field [0001] The invention belongs to the technical field of giant salamander breeding, and in particular relates to a method for artificial propagation of giant salamander. Background technique [0002] The giant salamander belongs to the Cryptochillidae family, the genus Giant salamander, and is the largest and most precious amphibian in the world; its cry is like a baby's cry, so people call it "baby fish"; It comes from the smell of sansho pepper on its body; salamander is a transitional type representing fish and reptiles, and is known as an ancient "living fossil". At the same time, salamander meat is white and tender, fat but not greasy. Known as "living ginseng" in the water; wild salamander resources are on the verge of extinction, and artificial large-scale breeding is the only way to restore the natural resources of salamanders and meet social needs. Due to the influence of various external factors, the survival rate of salamanders in the natural environ...
