Breeding method of andrias davidianus in simulated ecological mode

Abstract

The invention discloses a breeding method of andrias davidianus in a simulated ecological mode. The breeding method comprises the steps that a simulated ecological pool is built to conduct artificial breeding on the andrias davidianus; a breeding region with a high-quality environment is specially provided for breeding of the andrias davidianus in the simulated ecological pool, and the light intensity range of the breeding region is controlled within 50-300 Lux; a traditional Chinese medicine hanging bag is arranged on the water inlet of the breeding region, and the traditional Chinese medicine comprises eucommia ulmoides, radix polygoni multiflori and epimedium brevicornum maxim; the breeding region is not additionally covered with a sunshade net in the breeding process. The traditional Chinese medicine with the ratio of the eucommia ulmoides, the radix polygoni multiflori and the epimedium brevicornum maxim being 3:1:1 is adopted to conduct hanging bag breeding, accordingly the spawning rate, fertilization rate and hatching rate of parent andrias davidianus are improved by 10-20%, and the traditional Chinese medicine effectively promotes synchronization of male and female and is green and non-polluting and harmless to environment; the light intensity range of the breeding place is controlled within 50-300 Lux, and the gonad development of the andrias davidianus can be improved.

Description

technical field [0001] The invention relates to the field of giant salamander breeding, in particular to a method for breeding giant salamanders in a simulated ecological mode. Background technique [0002] The state stipulates that only the second generation of giant salamanders (salamanders) can be eaten and traded. Illegal capture, hunting, trafficking, and consumption of wild giant salamanders will be punished by law. It is reported that the annual captive breeding of Chinese giant salamanders has exceeded 1.6 million. According to statistics, the natural resource reserves of giant salamanders are about 90,000, mostly in hilly and mountainous areas. Due to the aggravation of industrial pollution in economically developed areas, the resources are even more insufficient. Due to the great edible, medicinal and ornamental value of giant salamanders, in recent years, the phenomenon of overhunting giant salamanders has become increasingly rampant, coupled with the destruction...

Problems solved by technology

By establishing an ecological simulation ecological pool, on the one hand, provide the giant salamander with an environment with abundant food and suitable conditions in all aspects, and on the other hand, let the giant salamander reproduce naturally in the natural environment, which will help solve the problem that the male and female gonads of the giant salamander cannot be synchronized. Control the light intensity of the breeding site to 50-300Lux, which can promote the development of giant salamander gonads
