Description
Technical field
The present invention relates to the producing method for seed of a kind of fish, particularly relate to a kind of preparation method of giant salamander seminal fluid preserving agent, this technology belongs to biological technical field.
Background technology
Giant salamander is commonly called as the giant salamander, is China institute special product, belongs to animals on the brink of extinction, is classified as two classes by country and lays special stress on protecting wildlife.By large-scale farming in recent years, giant salamander germ plasm resource is degenerated serious, and growth rate significantly descends, and various diseases takes place frequently.Carry out the seed selection of giant salamander superior families, significant for increasing economic efficiency etc.
Expensive due to kind of salamander, the artificial breeding giant salamander, environment, equipment requirement is high, technical difficulty is large, and the raiser that therefore will cultivate the commodity giant salamander and lack experience must arrive that aqua-marine life is raised and train breeding and operation utilizes the regular breeding field of licensing to obtain the giant salamander seed.In order to improve the survival rate of giant salamander, should select to hatch emerge 3 months, the long giant salamander fry more than 5 centimetres of body.Giant salamander fry is in transportation, and the activity of temperature and giant salamander, oxygen demand etc. have close relationship.When adopting the oxygenation transportation, in 40 took advantage of 40 bag, the seedling of 6-12 centimetre can not surpass 60 tails at most.The transportation giant salamander fry is bred not as transportation giant salamander seminal fluid, and therefore, exploitation giant salamander seminal fluid preserving agent has economic worth especially.
Summary of the invention
The present invention aims to provide a kind of preparation method of giant salamander seminal fluid preserving agent.

216-32 mmol/L, MnCl
21-2 mmol/L, natrium adetate 2-5 mmol/L, vitamin C 2-5 mmol/ L, vitamin D 2-5 mmol/ L, vitamin E 2-5 mmol/ L, mannitol 100-200 mmol/L, spirulina polysaccharide 100-200 mmol/L, all the other are water.
Sodium chloride 30-60 mmol/L, sodium dihydrogen phosphate 2-5 mmol/L, sodium hydrogen phosphate
4-10 mmol/L; Sodium bicarbonate 2-5 mmol/L, sodium carbonate 4-10 mmol/L, iron chloride 6-12 mmol/L, calcium chloride 8-16 mmol/L, magnesium chloride 16-32 mmol/L, zinc chloride 16-32 mmol/L, manganese chloride 1-2 mmol/L, natrium adetate 2-5 mmol/L, vitamin C 2-5 mmol/ L, vitamin D 2-5 mmol/ L, vitamin E 2-5 mmol/ L, mannitol 100-200 mmol/L, spirulina polysaccharide 100-200 mmol/L, all the other are water.
With the proportionally weighing of above composition, and the water dissolving, constant volume.
2. the specific process of a kind of preservation giant salamander seminal fluid of the present invention is:
1) choose the giant salamander milter of gonad maturity, gather ripe seminal fluid;
2) preserving agent with claim 1 dilutes the giant salamander seminal fluid;
Dilution time is according to, giant salamander seminal fluid: dilution is with " 1-3 ": the dilution proportion of " 15-45 "; In the time of dilution: temperature is 10-15 ℃.
Spirulina polysaccharide: from the physiologically active polysaccharide that spirulina extracts, nontoxic.Proterties: colourless or pale yellow powder.Water-soluble, be insoluble to pure and mild grease.Quality index: outward appearance: colourless or pale yellow powder.
Spirulina polysaccharide: by suppressing free-radical oxidation reaction in body, reduce lipid peroxidation, reduce the formation of organizing lipofuscin, can reach the effect that slows down body aging.
Spirulina polysaccharide energy: strengthen the proliferation of bone marrow cells vigor, promote DNA to repair synthesis, good radiation-resisting functional is arranged and reduce radiotherapy, side effects of chemotherapy, ionization radiation injury is had obvious protection effect.
Spirulina polysaccharide energy: improve the nonspecific cellular immune function of body, and can promote body to turn different in nature humoral immune function, improve the ability of low imperial germ, poisoning intrusion.
The spirulina polysaccharide energy: promote the immune organ growths such as thymus gland, spleen gland, the Promote immunity haemocyanin is synthetic, eliminates immunodepressant to immune inhibitory action.
A kind of extracting method of spirulina polysaccharide includes, without being limited to: spirulina raw material is immersed in the water, is placed in the ice of-15 ℃ freezing 72 hours after stirring evenly, take out quick thawing, and centrifugal filtration, algae-residue extracts spirulina polysaccharide; Add Na in filter residue
2CO
3Be dissolved into solution, centrifugal filtration discards filter residue, keeps filtrate. regulate filtrate pH to neutral, and concentrated, atomized drying.
Giant salamander breeding population of the present invention is cultivated and genital regulating:
The giant salamander breeding population is set up the breeding archives, propagating concentrated raising cultivation under condition artificially, reach the 2-3 monthly age.The year of breeding population cultivates temperature and is controlled at 12-24 ℃, adopts normal sunshine, and mating season, water temperature was controlled at 10-15 ℃, light application time 6-8h, and intensity of illumination 800-1200lux, the Continuous irradiation 0.5-1 month, the current exchange capacity is 2-3m
3/ h,
Parent population utilizes commercially available erbium material to feed at anestrous season,
Utilize mating season the commercially available erbium material that adds 5% earthworm to feed.
Reach sexual maturity, output mature egg and sperm through above cultivation.
Semen collection and transportation
Select sexually matured milter, adopt belly extrusion collecting semen, dry around the milter cloacal aperture, draw milky white seminal fluid with glass pipette, do not draw the yellow urine of discharging.The seminal fluid that gathers is all contained in the vial of drying of 20ml, the vial that seminal fluid is housed is placed on ice.Seminal fluid is avoided the light direct projection in transporting the way.
The giant salamander seminal fluid of long-distance transport is used for the method for breeding
1) choose giant salamander milter and the raun of gonad maturity, gather respectively ripe seminal fluid and ovum;
2) with preserving agent dilution giant salamander seminal fluid of the present invention.
Dilution time is according to, giant salamander seminal fluid: dilution is with (1-3) ml: (15-45) dilution proportion of ml; In the time of dilution: temperature is 10-15 ℃.
The giant salamander seminal fluid of dilution is evenly mixed with the ovum grain, and ovum grain and seminal fluid volume ratio are (15-30) ml: (0.1-0.5) ml, 10-15 ℃ of standing 5-20min after stirring adds appropriate 10-15 ℃ of streams water artificial insemination.
3) acquisition of giant salamander fry: fertilized egg is moved in 10-15 ℃ of streams water hatch, according to conventional giant salamander seedling and seed production process management, cultivate the giant salamander fry.
The cultural method of giant salamander fry
At 4 1m
3In water vat, raise respectively, use in early days miniflow water, every day exchange capacity 0.3m
3, keep water quality pure and fresh, sooner or later remove precipitation at the bottom of the pond every day for each 1 time.
Put newly hatched larvae quantity in the 1st water vat in a suitable place to breed about 4000 tails, do not throw in pellet
Put volt ground fish seedling (the long 1cm of body) 2000 tails in the 2nd water vat in a suitable place to breed, pellet particle diameter 80-100 μ m,
