Ecotype-imitating breeding system for andrias davidianus

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...

AI Technical Summary

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
