Four, the cultivation of giant salamander parent
1, giant salamander germinated in 3 ~ April, and during this period, the optimization feed described in nursing, feeds 3 times weekly, and feed injected volume is grasped by 2/15 of giant salamander body weight at every turn, and carries out the operation of dissolved oxygen amount test, regulating water quality, control water temperature before feeding intake at every turn.
2, at On The Gonadal Development of Megalobatrachus Davidianus tend to ripe in 5 ~ September, lay eggs after maturation, during this period, optimization feed described in nursing, feed 3 times weekly, feed injected volume is grasped by 1/5 of giant salamander body weight at every turn, and carries out the operation that pond water-soluble oxygen measures examination, regulating water quality, control water temperature before feeding intake at every turn, and increased water flow amount and current sound.
3, giant salamander lays eggs period, raises together with mode then monitoring in artificial 24 hours, if haul out outside hole by chalaza after spawning and fertilization, put into young salamander hatchery and carry out artificial incubation for female, hero; Then separation net was removed in first about 15 days at spawning and fertilization for independent Domestication method, female, male parent is mixed, after spawning and fertilization, chalaza is hauled out outside hole, put into young salamander hatchery and carry out artificial incubation.Wherein, the specific practice of artificial incubation is: the nylon bolting silk framework of preparation is put into hatchery, and 25 ~ 30cm at the bottom of framework bottom distance pond, is then evenly placed in fertilized egg in framework.Between the incubation period, frequent inspection embryonic development situation, rejects unfertilized egg in time.
4, the cultivation of young salamander and young salamander
Long 2.5 ~ the 3.0cm of young salamander body after membrane, withdrawn by nylon bolting silk framework, young salamander feeds 30 days in young salamander hatchery, during this period, without the need to throwing in bait, keeps circulating water, water temperature 10 ~ 15 DEG C, in time cleaning ight soil and metabolism foreign material.Wherein, it is 18 DEG C ~ 23 DEG C that hatchery water temperature controls, illumination requires to be strict controlled within the scope of 300 ~ 500lx.
5, young salamander is fed about 30 ~ 40 days in young salamander hatchery, be transferred in time described young salamander to raise and train pond raise and train from young salamander hatchery, wherein, children salamander raises and train pond depth of water 30cm, it is 13 ~ 20 DEG C that water temperature controls, children salamander is raised and train pond and adopts circulating water, enters the circulating water that young salamander raises and train pond and needs the strict indices controlling its temperature, dissolved oxygen amount and water quality; During children salamander is raised and train, the optimization feed described in feeding, throws in bait once in two days, and the impurity that cleaning ight soil and young salamander metabolism in time produces, until when young salamander body weight reaches 100g, proceed to into salamander culturing pool and raise and train, raise and train and strictly control every factor of influence.
Result is added up, and see the following form 1(remarks: emerging described in table is and hatches young salamander, and described surviving is young salamander and grows up to one-tenth salamander)
As seen from Table 1, raise together with the emergence rate of mode obviously higher than supporting mode separately, its analysis of causes is: raise together with in mode, can be fertilized in time after parent is laid eggs, high by precision.During mode of supporting separately is raised and train, after female, male parent lays eggs, can not be fertilized in time, low by precision.
In order to further illustrate beneficial effect of the present invention, the result of the present invention and the 200710018264.X patent No. is done to contrast below, in Table 2(remarks: in table, A represents data of the present invention, B is the data statistics of the 200710018264.X patent No.)
| Parent group number | Egg laying amount (grain) | Often group lays eggs (grain) | Emerge | Emergence rate | |
| A | 100 | 39973 | 400 | 34359 | 86.0% |
| B | 26 | 9699 | 373 | 8287 | 85.5% |
Discussion of results: as seen from the above table, artificial incubation technique after employing natural spawning, natural insemination, improve giant salamander breeding emergence rate, giant salamander emergence rate is subject to the impact of giant salamander parent self, is also subject to the impact of water temperature, illumination, water body dissolved oxygen amount.In giant salamander Ecology cultural technique, the factor of strict control effect giant salamander growth is the guarantee improving emergence rate, survival rate.
