Abstract
The invention discloses a giant salamander parent breeding method which comprises the following steps of: establishing a giant salamander parent breeding tank; disinfecting the breeding tank; initially selecting giant salamander parents; disinfecting the giant salamander parents; immersing each adult salamander by independently using 0.15-0.25 g of furan drug per cubic meter of water or 0.3-0.6 g of methylene; lightly putting medicinal liquid and numbered adult salamanders together into the breeding tank to be bred independently; carrying out a breeding test; and culturing the remained adult salamander parents in a reinforced manner to prepare before hastening parturition. The giant salamander parent breeding method disclosed by the invention has the benefits as follows: giant salamander parents are screened step by step through individual robustness breeding, hydrogen power adaptability breeding and salinity domestication breeding; individual robustness, water stimulation resistance and disease resistance of the giant salamander parents are increased; and the culture benefit is increased.
Description
Technical field
The present invention relates to a kind of giant salamander parent selection, belong to the giant salamander culture technical field.
Background technology
Giant salamander is a kind of famous and precious medicinal animal, also is a kind of high economic animal that is worth, and its fine and tender taste, unique flavor, nutritive value are high, contain 17 seed amino acids in its meat albumen, wherein have 8 kinds to be the amino acid of needed by human, are called as " living fossil ".Last century the seventies, the quantity of the giant salamander sharply descends, the resource exhaustion in many places, even endangered.And at present, along with the ripe and popularization of giant salamander artificial culture technology, the quantity of giant salamander has had obvious increase.
Propagate artificially in the process giant salamander, the quality of giant salamander parent seed selection situation affects the breed of giant salamander; Make a crucial step in the giant salamander artificial breeding; The seed selection of giant salamander is intended to improve giant salamander parent's individual robustness, anti-water quality stimulates and disease resistance, yet the selection to grow up giant salamander age, body weight aspect is only adopted in giant salamander parent's seed selection at present usually; And there are not specific method and step; The giant salamander parent who selects has randomness, and giant salamander the parent differ greatly, and is unfavorable for the popularization of giant salamander artificial culture technology.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of giant salamander parent selection is provided, select the giant salamander parent that individual strong degree is high, anti-water quality excitant is strong and disease resistance is good.
The objective of the invention is to realize through following technical scheme: a kind of giant salamander parent selection, it comprises following steps:
(1) build giant salamander parent seed selection pond: in the diversion cavern, build 50～100 giant salamander parent seed selection ponds, the area in seed selection pond is 4～10m
2, the degree of depth is 0.6～0.8m, and water level is controlled at 0.2～0.5m, and pH value is 6.5～7.5, and the anti-net of escaping is installed at top, seed selection pond;
(2) seed selection pond sterilization: behind harmful organisms such as disinfectant kill bacteria or parasite, leave standstill for 1～February, clear water is introduced in water flushing back;
(3) giant salamander parent's primary election: select 3～4 ages, body weight 2～4kg, active naturally one-tenth salamander, and every one-tenth salamander is numbered, set up giant salamander parent individual information archives;
(4) giant salamander parent's sterilization: become salamander to convert the water logging bubble 5～8 minutes with every cubic metre of water body 0.15～0.25g of nitrofurans or methylene 0.3～0.6g separately to every, then with liquid medicine with number after become salamander together to put into the seed selection pond gently to culture separately;
(5) seed selection test:
A, individual robustness seed selection: after treating the one-tenth salamander adaptation in the seed selection pond, to the normal feeding of one-tenth salamander in each seed selection pond, feeding time is 6～10 days; The back changes food species, observes into the reaction of salamander, in case the phenomenon that has giant salamander food refusal to occur or tell food; Pick out immediately, and carry out the individual information record;
B, the seed selection of acid-base value adaptability: carry out water quality pH value abnormal test, the pH value of control water quality is observed into the reaction of salamander at 6.0～6.8 sour environment and 7.2～8.0 alkaline environment, selects wherein individual active naturally one-tenth salamander, carries out the individual information record;
C, salinity domestication seed selection: increase the salinity of fresh water in the seed selection pond, concrete operations are to pull remaining one-tenth salamander out the seed selection pond; After transferring to 0.05 to the pond salinity water, put into into salamander, adapt to after 4～6 days; To become salamander to pull the seed selection pond out once more, transfer to 0.1 to the pond salinity water after, put into into salamander; Observe into the reaction of salamander, select wherein individual active naturally one-tenth salamander, carry out the individual information record;
(6) to remaining one-tenth salamander parent hot housing, the preparation before hastening parturition.
Described giant salamander parent seed selection pond is rounded, and the bottom is built into by cobblestone.
Described disinfectant is the bleaching powder of 0.8～1.2PPM or the 90% crystal chlorophos of 0.2～0.5PPM.
The invention has the beneficial effects as follows: progressively screen the giant salamander parent through individual robustness seed selection, the seed selection of acid-base value adaptability, salinity domestication seed selection, improved giant salamander parent's individual strong degree, anti-water quality excitant and disease resistance, improved culture benefit.
