The artificial breeding technology for the schizothorax grahami is capable of effectively improving the problems of low survival rate, slow growth and low reproductive capacity of artificial schizothorax grahami breeding, improving the yield and economical benefit of the schizothorax grahami and promoting the development of the schizothorax grahami breeding industry.
Description
Technical field
The present invention relates to a kind of Schizothorax grahami artificial culture technology, particularly relate to and scale can cultivate rapidly a large amount of Schizothorax grahami, increase economic efficiency.
Background technology
Schizothorax grahami is edgy, and skip capability is strong, the cold aqueous small fishes of Plants feeding habits that stress reaction is strong; Fine and tender taste, delicious flavour, muscle nutrition is worth higher, is a kind of high-grade edible fish.Its wild fish difficulty is raised and train, and survival rate is low, and sexual maturity is late, and fertility is low, and growth is slow simultaneously, and happiness is jumped, and to body muscle consumption greatly, affects seed output and quality.How by captive Schizothorax grahami, available protecting, expand its germ plasm resource, improve Schizothorax grahami cultivation scale and economic benefit, become the Main way of research.
Summary of the invention
The object of the present invention is to provide a kind of more effective artificial propagation technology for schizothorax grahami, improve the output of Schizothorax grahami, increase economic efficiency.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of Schizothorax grahami artificial culture technology, comprises the following steps:
Cleaning pond also with lime disinfection, is cultivated water quality after removing weeds and pest, is kept certain water velocity, put fingerling in a suitable place to breed after 2 weeks;
Select healthy and strong parent population during April to carry out taming and hastening parturition laying eggs;
Adopt nature hatching method, regulate water temperature to promote fry hatching;
Start to throw something and feed after 7 days, regulate according to membrane time of fry and growing state throw something and feed feed kind and weight, culturing time about 18 months, can fish for listing
On the basis of technique scheme, the present invention can also do following improvement:
Fishpond comprises Ecology flowing water pond, hatchery and cultivation pond; The mouth of a river, fishpond adopt with diagonal way arrange, bury plastic tube underground and mounted valve to control the water yield; Water filling port is higher than the pond water surface, and discharge outlet and water, with high, install sieves; With lime disinfection, 2-3 week injects new water, water cleaning; Ecology stream sump water temperature 13-18 DEG C, flow velocity 0.01-0.03m/s, cultivate benthic diatom with 60 mesh sieve tulles; Place enough clean brown sheets, willow root or pasture and water etc. as fish nest, prevent the harm of the animals such as snake, the frog, mouse; Note current check.
Further described parent population is thrown in, the concrete grammar of domestication is as follows:
Select wild fish, specification requirement is homogeneous, about 500g/ tail, build is rectified, physique is healthy and strong, without sick and wounded, fin is complete; Every square metre of stocking rate is 15 tails, and female-male proportion is 2:1; Throw at fine noon at weather mid-March; Throw something and feed after 15 days a small amount of artifical compound feed, increase feed gradually, after 45 days, feeding volume can reach about 5% of fish body weight.
Further described artificial propagation concrete grammar is as follows:
Water temperature 13-16.5 DEG C, during mid-April, raun belly expands, soft, tool elasticity, and injection ocyodinic comprises human chorionic gonadtropin (HCG), fish ovulation induction element No. 2 (LRH-A2), fish maleic acids DOM (DOM); Hasten parturition and select fine day to carry out the morning, amount to two pins, interval 48h; First pin injection volume is HCG 800IU/kg+LRH-A2 8 μ g/kg, second pin injection volume is HCG 500IU/kg+LRH-A2 15 μ g/kg+DOM 5mg/kg, be injected between raun midline abdominal chest and abdomeinal fin, milter is not injected, after laying eggs, ovum grain is taken out in time and carries out nature hatching, and supplement new fish nest in time.
Further described natural hatching method concrete grammar is as follows:
Stayed by fish-egg in hatchery, water temperature remains on about 15 DEG C, and about 165h gets final product membrane.
Concrete grammar is propagated artificially as follows further:
Throw something and feed after being blended by red line worm after just incubating fish 7d, make open-mouthed bait, injected volume is 30g/ ten thousand tail, throws something and feeds every day 4 times; After 20d, proceed to and cultivate in pond, area 10m
2left and right, the dark 30-40cm in pond, flow velocity 0.03-0.05m/s, throw something and feed and rise rope particulate fry and turn food opening material, river soft-shelled turtle seedling material of throwing something and feeding after 2 days, fry body weight is when below 30g, day feeding volume is the 8%-10% of fry body weight, fry body weight when 30-100g, day feeding volume be the 6%-8% of fry body weight, point morning, noon and afternoon throw something and feed for 3 times; Specification reaches 100g/ tail, be then fingerling, proceed to Ecology flowing water pool cultivated, 10 tails/m
2throw in, feed of throwing something and feeding is that river group is bred as material, day feeding volume be about 5% of fry body weight, point sooner or later throw something and feed for 2 times, water temperature 12-20 DEG C, culturing time is 18 months, and average weight can reach 1.1kg, reaches listing specification.
The invention has the beneficial effects as follows:
Complete the domestication process of Schizothorax grahami, the spawning rate after artificial induced spawning and reproduction rate increase, and fingerling grows neatly, and survival rate is high; Cost is low, and cultivation speed is fast, and output is improved, high financial profit.
