(4) water quality on the existence impact of giant salamander greatly, must guarantee the water quality of suitable giant salamander existence, wherein, brood pond water requirement salinity is high, hardness is large, transparency is large, pH maintains between 6.5～7.5, and dissolved oxygen amount is 7.6～8.4mg/l, wherein, at the bottom of duty is changed water, diligent blowdown, periodic flushing pond, be regularly the concrete grammar of regulating water quality with viable bacteria water purification agent regulating water quality.
Three, the selection of giant salamander parent and Domestication method
1, parent is selected: ripe healthy close salamander is the primary condition of carrying out Ecology giant salamander captive, select the age more than 5 ages, healthy, without wound, physique stalwartness giant salamander parent 200 tails, wherein, 3.5 kilograms of giant salamander parent average weights, male and female are respectively 100 tails.
2, the selection of Domestication method: the random selection female giant salamander parent of 50 tail and the male giant salamander parent of 50 tails, cultivate separately; Other giant salamander parents adopt method female, that hero is raised together with to cultivate.
Four, the cultivation of giant salamander parent
1, giant salamander germinated in 3～April, during this period, fed described optimization feed, fed weekly 3 times, and feed injected volume is grasped by 2/15 of giant salamander body weight at every turn, and before feeding intake, carried out the operation of dissolved oxygen amount test, regulating water quality, control water temperature at every turn.
2, in 5～September On The Gonadal Development of Megalobatrachus Davidianus trend maturation, after maturation, lay eggs, during this period, feed described optimization feed, feed weekly 3 times, feed injected volume is grasped by 1/5 of giant salamander body weight at every turn, and before feeding intake, carries out the operation of pond water-soluble oxygen measurement examination, regulating water quality, control water temperature at every turn, and increased water flow amount and current sound.
3, giant salamander lays eggs period, raises together with monitoring in artificial 24 hours of mode for female, hero, if chalaza is hauled out outside hole after spawning and fertilization, puts into young salamander hatchery and carries out artificial incubation; Within first about 15 days, remove separation net 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, framework bottom apart from pond at the bottom of 25～30cm, then fertilized egg is evenly placed in framework.Between the incubation period, the frequent embryonic development situation that checks, 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, withdraws nylon bolting silk framework, and young salamander is fed 30 days in young salamander hatchery, during this period, without throwing in bait, keeps circulating water, and 10～15 ℃ of water temperatures, clear up ight soil and metabolism foreign material in time.Wherein, hatchery water temperature control is 18 ℃～23 ℃,, 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, young salamander described in being transferred to from young salamander hatchery is in time raised and train pond and raises and train, wherein, children salamander is raised and train pond depth of water 30cm, water temperature control is 13～20 ℃, children salamander is raised and train pond and adopts circulating water, enters the strictly indices of control its temperature, dissolved oxygen amount and water quality of circulating water that young salamander is raised and train pond; Children is during salamander raises and train, and the optimization feed described in feeding, throws in bait once in two days, and clears up in time the impurity that ight soil and young salamander metabolism produce, until young salamander body weight while reaching 100g, proceeds to into salamander culturing pool and raises and train, raises and train the every factor of influence of strict control.
Result statistics, 1(remarks see the following form: emerging described in table is and hatches young salamander, described surviving is young salamander and grows up to becoming salamander)
As seen from Table 1, raise together with the emergence rate of mode obviously higher than supporting separately mode, its analysis of causes is: raise together with in mode, after parent is laid eggs, can be fertilized in time, be subject to precision high.During the mode of supporting is separately raised and train, due to after female, male parent lays eggs, can not be fertilized in time, be subject to precision low.
In order to further illustrate beneficial effect of the present invention, below the result of the present invention and the 200710018264.X patent No. is done to contrast, in Table 2(remarks: in table, A represents data of the present invention, and B is the data statistics of the 200710018264.X patent No.)
| ? | Parent group number | Egg laying amount (grain) | Every group lay 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 hatching technique after employing natural spawning, natural insemination, has improved giant salamander breeding emergence rate, and 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 assurance that improves emergence rate, survival rate.
