Bionics artificial reproduction method of large salamander

Abstract

The present invention provides bionic giant salamander domesticating and propagating process, which includes building artificial brook in original habitat of giant salamander, building caves covered with soil on two sides of the brook and planting vegetables to form conditions suitable for giant salamander to grow; and building stepped reservoirs in the upstream of the brook to ensure safe water quality. The bionic giant salamander domesticating and propagating environment can provide giant salamander with effective protection, and is favorable to the growth and propagation of giant salamander.

Description

technical field [0001] The invention relates to a method for imitating ecological artificial domestication and breeding of giant salamanders. Background technique [0002] The Chinese giant salamander (Andrias davidianus) is referred to as giant salamander, commonly known as giant salamander, and its English name is Chinese Giant Salamander. It belongs to Amphibia, Caudata, and Crybtobranchidae in classification. It is endemic to my country and The largest tailed amphibian is listed as a Class II key protected aquatic wild animal by the country. Due to the high edible and medicinal value of the giant salamander, large numbers of criminals have hunted and killed the giant salamander, coupled with the destruction of the giant salamander's habitat and low reproductive capacity in recent years, the giant salamander is in danger of extinction nationwide. In order to effectively save and protect the precious wild resources of giant salamanders, practice has repeatedly proved that ...

Problems solved by technology

However, the biggest disadvantages of adopting this domesticated breeding mode are: low maturity rate of salamander gonad development, low number of mature sperm and eggs with fertilization ability discharged after induction of labor, low fertilization rate of mature eggs, low hatching rate of fertilized eggs, The survival rate of juvenile salamanders and juvenile salamanders is low, but the mortality rate of parent salamanders is high, such as "five lows and one high" phenomenon

After 7 years of continuous experimental observation and research, although the original ecological breeding model of Chinese giant salamander has overcome many shortcomings of the fully artificial domestication and breeding model of Chinese giant salamander, there are still some shortcomings and deficiencies. Placed in natural rivers for feeding and bre
