Embodiment 1

[0034] A kind of giant salamander ecological imitation reproduction method of the present embodiment, comprises the following steps:

[0035] 1, a giant salamander imitation ecological propagation method, is characterized in that, comprises the following steps:

[0036] (1) Selection of ecologically imitative breeding sites:

[0037]Select mountain streams with an altitude of 700-1200 meters, limestone strata, rocky, gravel, and pebbles in the riverbed, dense vegetation, abundant water sources, and abundant rainfall to build giant salamander imitation ecological breeding ponds. The surface vegetation coverage on both sides of the stream is 80% Above, the water quality of the creek is: clear water, water temperature 16°C-22°C, water body rich in minerals, pH value 6.8-7.5, hardness 130-170, water body rich in dissolved oxygen, DO>5mg / L, water chemistry Oxygen consumption <12mg / L, ammonia nitrogen <0.06mg / L, total phosphorus <0.35mg / L;

[0038] (2) Construction of imitation ec...

Abstract

The invention discloses a giant salamander simulated ecological breeding method. The method includes the steps of selection of a simulated ecological breeding pool site, construction of a simulated ecological breeding pool, cultivation of parents of giant salamanders under simulated ecological conditions, hormone induction of the giant salamanders for natural spawning and natural fertilization, artificial hatching and domestication of young salamanders. Compared with the prior art, the method has the advantages that the giant salamander simulated ecological breeding method is high in egg production rate, fertilization rate and hatching rate, and the method has a great meaning for improving the breeding rate of the giant salamanders.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for imitating ecological reproduction of giant salamanders. Background technique [0002] The Chinese giant salamander, commonly known as the "salamander", is a rare wild animal with high economic value unique to my country. It is a national second-class protected animal and is a good material for studying biological evolution, biodiversity, and sex-determining molecular mechanisms. With great potential contributions to scientific research, they are called "living fossils". On July 1, 1975, the giant salamander was included in Appendix I of the Convention on International Trade in Endangered Species (CITES), prohibiting its international trade. On December 10, 1988, the State Council announced the "National Key Protected Wildlife List" and listed the giant salamander as a national second-class protected animal. In addition, giant salamanders are also listed as criti...
