Ecology imitating breeding pool capable of improving natural mating and egg-laying rate of brood salamanders

Abstract

An ecology imitating breeding pool for improving the natural mating and egg-laying rate of brood salamanders, which comprises a pool body, a crab pond, a fish and shrimp pond, a surge device, a predation platform, an egg laying trough and a protection device, the living crabs are put in to the pool body through the crab pond in the pool body, the fish and shrimps are put in the pool body through the fish and shrimp pond. The oxygen content of the water body discharged from the drain module is increased through the surge device, the living animals are captured by the predation platform for predation of the brood salamanders, the mating and oviposition are carried out through the egg laying trough, the gonadal maturity is started synchronously, the protection of the young salamanders is carried out by the protection device, the injury is avoided, and the young salamanders are guided to enter the breeding pool. The breeding pool overcomes the problems of low natural breeding rate and survival rate of young salamanders in the prior art. The breeding pool has the advantages of simple structure, high oxygen content in the water body, feeding of living animals for the predation of the salamanders to improve the activity and the wildness of the species, the development of the gonads of the salamanders is promoted, the gonads become mature synchronously, the interfering with the salamanders is avoided, the young salamanders are protected from damage, the natural mating rate is high, and the survival rate of the larvae is high.

Description

technical field [0001] The invention belongs to the technical field of breeding, and relates to an ecological imitation breeding pond for improving the natural mating and spawning rate of salamanders. Background technique [0002] Salamander, also known as giant salamander, mainly grows in valley caves with clear and cool water. At present, artificial breeding is more popular, but affected by environmental factors, it is difficult to reproduce naturally under artificial breeding conditions. The problem lies in the range of activities and space. Limited, using the method of feeding dead animals, the movement and wildness of the breeding salamander are limited, the amount of exercise is low, the female ovary is poorly developed, the male hormone is too low, the sperm activity is not enough, resulting in non-mating, or the ovary is not easy to fertilize after mating, and the gonad development cannot be synchronized Tend to maturity, low survival rate of larvae. Contents of th...
