Problems solved by technology

Artificial reproduction is less affected by natural environmental conditions, with high controllability and high spawning rate. However, artificial reproduction has high technical requirements for operators. At present, the number of experts engaged in artificial cognition of giant salamanders in the country is limited and cannot meet market demand.
Ecological imitation breeding is relatively less dependent on technology, but has high requirements on the environment, and should not be used in areas where the ambient temperature is too high or too low
The problems of the above two reproductive techniques are that the giant salamander gonads cannot mature, the sperm motility is poor, and the induction rate, fertilization rate and hatching rate are low

Embodiment 1

[0027] An imitation ecological breeding system for giant salamanders. In the aquaculture base, a new ecological breeding pond is excavated to build an imitation ecological breeding system; the combination of the protection system of the imitation ecosystem, the industrial control system and 10 imitation ecological breeding units is used to realize artificial Real-time adjustment of system environmental factors, cave environment factors and water environment factors in the breeding process to achieve the goal of giant salamanders growing in a near-wild environment, so as to produce green and healthy commercial giant salamanders and seedling salamanders with fully mature gonads, and realize the growth of giant salamanders. Large-scale ecological healthy farming model. The system environmental factors here mainly refer to system environmental factors such as system temperature, system humidity, and vegetation coverage in the imitation ecological breeding environment; cave environm...

Abstract

The invention discloses an ecotype-imitating breeding system for andrias davidianus, belonging to the technical field of aquaculture. According to the invention, an ecological breeding pond is dug ina selected aquaculture base, and an ecotype-imitating breeding system is established; and by utilization of the combined action of a protection system, an industrial control system and a plurality ofecotype-imitating breeding units of the ecotype-imitating breeding system, system environment influence factors, cave environment factors and water environment factors in the breeding process are manually adjusted in real time, and the purpose that the andrias davidianus grows in a near-wild environment state is achieved, so green and healthy commercial andrias davidianus and breeding andrias davidianus with sufficiently mature gonad are produced, and a large-scale ecological healthy breeding mode of the andrias davidianus is realized. The yield of the commercial andrias davidianus bred by using the ecotype-imitating breeding system provided by the invention is increased by 20%; the proportion of the breeding andrias davidianus with sufficiently mature gonad in the breeding andrias davidianus is about 90%; and the problems of a conventional andrias davidianus breeding technology are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a giant salamander imitation ecological breeding system. Background technique [0002] Giant salamander is the largest and most precious amphibian in the world. Its cry is very similar to the cry of a baby, so people also call it "baby fish". The giant salamander is a national second-class protected amphibious wild animal. It is a key development of agricultural industrialization and characteristic agriculture and a species of wild animal genetic protection. Giant salamanders have very high value in ornamental, nutritional and medicinal purposes, so the market value of giant salamanders has always been high. The breeding and breeding industry of giant salamanders is also constantly developing, but giant salamanders have very high requirements for the living environment. [0003] At present, there are two main breeding technologies for giant salamanders: artifici...
