Abstract
The invention proposes a kind of induced spawning methods of giant salamander artificial propagation, and first according to the weather of giant salamander breeding base locality, the natural conditions such as water temperature and quality establish a small-scale outdoor Ecology breeding base；Then, in outdoor Ecology breeding base giant salamander oviposition situation, promote the sexual maturity to the giant salamander parent in corresponding breeding base, make its oviposition.This method combines man and nature, accurate to grasp promoting the sexual maturity the time for giant salamander in 1 year by observation using Ecology principle, the emergence rate of current year is made to improve 13%~17% or so, successively improves yield, reduces cost, increase income for raiser.
Description
Technical field
The present invention relates to animal artificial propagation field more particularly to a kind of induced spawning methods of giant salamander artificial propagation.
Background technique
Currently, the domestic raiser for being engaged in giant salamander artificial propagation has many families, the means taken are mostly：It is promoted the sexual maturity with drug,
So that male and female giant salamander is synchronized maturation, then manually draw ovum, artificial semenpicking, fertilization are put into hydrostatic or microcirculation water later and hatch directly
To emergence.There are following difficult points for this method：1, the time of promoting the sexual maturity of male and female giant salamander is difficult to determine, 2, promote the sexual maturity used in male and female giant salamander
The bad control of the ratio of drug, the Best Times promoted the sexual maturity in 3, one years are difficult to grasp；Lead to the emergence rate of giant salamander in reproductive process
It is not satisfactory, generally only 10%~30% or so.
The exploration that artificial propagation is carried out to giant salamander is set about in China from the eighties with regard to someone, until today, to the medicine used
It promotes the sexual maturity between object and ratio and male and female giant salamander the time being separated by, semen collection, the technologies such as fertilization are grasped, but substantially to giant salamander one
The Best Times promoted the sexual maturity in year, still among exploration.
Summary of the invention
For the emergence rate for improving giant salamander artificial propagation, the present invention proposes a kind of induced spawning method of giant salamander artificial propagation.
For this purpose, the technical scheme is that：A kind of induced spawning method of giant salamander artificial propagation, it is characterised in that by following step
Rapid composition：
1）According to the weather of giant salamander breeding base locality, it is bionical to establish a small-scale outdoor for water temperature and quality natural conditions
State breeding base；
2）According to the oviposition situation of giant salamander in above-mentioned outdoor Ecology breeding base, to the giant salamander parent in corresponding breeding base
This is promoted the sexual maturity, its oviposition is made, and concrete operations mode is divided to two kinds：1, for the giant salamander parent being placed in outdoor breeding base, when
When giant salamander parent natural spawning to three tail in outdoor Ecology breeding base, at once to extensive big in outdoor breeding base
Salamander parent promotes the sexual maturity, and makes its oviposition；2, for the giant salamander parent being placed in indoor propagation base, when outdoor Ecology breeds base
When giant salamander parent natural spawning to five tail in ground, promote the sexual maturity at once to the extensive giant salamander parent in indoor propagation base,
Make its oviposition.
Beneficial effect：
Giant salamander is 1 year mature primary, but annual maturation time is different.Climate change, the natural conditions such as water quality water temperature
The maturity period of giant salamander is all directly affected, so, the maturation time of giant salamander is different in different region 1 year, therefore cannot
The giant salamander maturity period on his ground is calculated as the local giant salamander maturity period.
This method utilize Ecology principle, in conjunction with the water temperature difference of indoor and outdoor, and beat promote the sexual maturity needle after need through three to
This common sense of phase is fermented in sexal maturity in four days, when giant salamander natural spawning to half in outdoor Ecology base, at once to interior
Giant salamander parent for breeding promotes the sexual maturity, time of otherwise having promoted the sexual maturity early ovum does not have a maturation, evening and ripe crosses.
The present invention combines man and nature, accurate to grasp 1 year in the middle greatly by observation using Ecology principle
Salamander is promoted the sexual maturity the time, so that the emergence rate of current year is improved 13%~17% or so, is successively improved yield, reduce cost, is raiser
Increase income.
Specific embodiment
The present invention will be further described with reference to embodiments.
Example 1
A kind of induced spawning method of giant salamander artificial propagation, comprises the steps of：
1）A small-scale outdoor breeding base is established beside the giant salamander breeding base built up, that is built is small-scale
Outdoor breeding base in water temperature and quality to be consistent with the water temperature and quality in the outdoor giant salamander breeding base built up；
2）100 giant salamander parents for being used to breed are placed in above-mentioned outdoor giant salamander breeding base and are raised, by 10 pairs of giant salamanders
Parent is placed in above-mentioned small-scale outdoor breeding base and raises；
3）When giant salamander parent natural spawning to 3 tail in above-mentioned small-scale outdoor breeding base, at once to above-mentioned room
100 giant salamander parents in outer giant salamander breeding base promote the sexual maturity, until oviposition.
Example 2
A kind of induced spawning method of giant salamander artificial propagation, comprises the steps of：
1）A small-scale outdoor breeding base is established beside the indoor giant salamander breeding base built up, that is built is small
Water temperature in the outdoor breeding base of scale in water temperature and the indoor giant salamander breeding base built up is inconsistent；
2）100 giant salamander parents for being used to breed are placed in above-mentioned indoor giant salamander breeding base and are raised, by 10 pairs of giant salamanders
Parent is placed in above-mentioned small-scale outdoor breeding base and raises；
3）When giant salamander parent natural spawning to 5 tail in above-mentioned small-scale outdoor breeding base, at once to above-mentioned room
100 giant salamander parents in interior giant salamander breeding base promote the sexual maturity, until oviposition.
It is accurate to grasp promoting the sexual maturity the time for giant salamander in 1 year by observation using Ecology principle in this method, make
The emergence rate of current year improves 13%~17% or so, successively improves yield, reduces cost, increase income for raiser.
Claims (1)
1. a kind of induced spawning method of giant salamander artificial propagation, it is characterised in that comprise the steps of：
1）According to the weather of giant salamander breeding base locality, it is numerous to establish a small-scale outdoor Ecology for water temperature and quality natural conditions
Grow base；
2）According to the oviposition situation of giant salamander in above-mentioned outdoor Ecology breeding base, to the giant salamander parent in corresponding breeding base into
