Giant salamander breeding method taking into account both imitation ecological reproduction and artificial reproduction

Abstract

The invention relates to a giant salamander breeding method considering imitative ecological reproduction and artificial reproduction; existing artificial reproduction technologies mostly employ steroid injection spawning, thus causing large damages on giant salamander; the novel method builds a giant salamander natural habitat environment on one hand, and adds infrared sensors in artificial caves of the giant salamander; the infrared sensors are connected with a monitoring computer through a data line; when the monitoring computer discoveries that the infrared rays sent by infrared ray emitters of certain artificial cave are blocked for more than 2 minutes, the giant salamander in the artificial cave is determined to have crawled to a showering pipe for showering once; if the giant salamander of certain artificial cave has 5 or above times of showering within 12 hours, the giant salamander is determined to be natural reproduced giant salamander, steroid injection spawning is not needed, and imitative ecological reproduction is carried out; steroid injection spawning is carried out for the resting giant salamander. The giant salamander breeding method considering imitative ecological reproduction and artificial reproduction is high in breeding rate, good in population biology, and suitable for culturing and breeding giant salamander.

Description

technical field

[0001] The invention relates to a giant salamander breeding method that takes both ecological imitation breeding and artificial breeding into consideration. Background technique

[0002] The artificial propagation technology of giant salamander is a technical problem at present, and it is the main factor restricting the healthy and sustainable development of giant salamander aquaculture. At present, the artificial reproduction of giant salamander is to borrow the fish oxytocin reproduction technology, that is, to inject exogenous oxytocin drugs (such as HCG, LRH-A) to the female and male broodstock whose gonads have developed to a certain degree (stage IV). 2 , dioconone, etc.), rapidly increase the hormone content in fish blood in a relatively short period of time, and transmit it to the corresponding organs and glands of fish through blood flow, partially replacing fish neuro-endocrine regulation activities, thereby promoting The gonads are mature, ejacula...

Embodiment approach 1

[0048] Embodiment 1: This giant salamander breeding method that takes into account both benefits and species conservation includes the following steps:

[0049] 1). Site selection of breeding facilities

[0050] (1) Geographical environment selection: warm, humid and cool mountainous areas with an altitude of 300m or more, annual average temperature of 12-17°C, rainfall of 600-2000mm, annual average sunshine hours of 2000-2600h, and forest coverage of more than 60%. , Choose a secluded and undisturbed place, and build a giant salamander breeding base of a corresponding scale according to the terrain.

[0051] Choose groundwater, mountain streams, cold spring water or bottom water of reservoirs with excellent and pure water quality, no pollution, convenient water intake, sufficient water volume, no inflow of industrial, medical and domestic sewage, and low water temperature as the water source. Water Environment Quality Standards (GB 3838-2002) "Class II and above" and "Fisher...
