Description
Technical field
The invention belongs to technical field of aquaculture, is related to a kind of Huso huso raun and Amur Sturgeon milter hybrid breeding side
Method.
Background technology
At present, China has become Yang Xun big countries of the world, and about 21000 tons of annual production accounts for world's sturgeon cultivation yield
89%.With the fast development of China's sturgeon cultivation industry, the problems such as hybridize that breed variety is chaotic, there is no excellent Cultivars increasingly
Prominent, seriously constrain the sound development of China's Acipenser Sinensis industry.At present, China's sturgeon cultivation kind mostly is wild and raises and train kind, raw
On product, breed variety is chaotic, mostly is the chaotic cenospecies of some little plants, and culture performance is low.Except China there is no Acipenser Sinensis excellent
Outside kind, the such as country such as the former Soviet Union, Germany, the U.S. and Iran of other sturgeon cultivation big countries cultivates and is suitable for this country's cultivation
The master of environment supports kind.For example, the little huso sturgeon sturgeon (Europe huso sturgeon Husohuso ♀ × sterlet Acipenserruthenus ♂) of the former Soviet Union,
The siberia platform of Germany, height the head sturgeon and paddlefish etc. in the U.S. are respectively provided with the breeding environment in native country and grow fast, premunition
The advantages of strong and early sexual maturity.Therefore, the Acipenser Sinensis new varieties for cultivating suitable China native country cultivation are badly in need of in China, optimize and improve
The structure of China's sturgeon cultivation kind.
Amur sturgeon, sturgeon are Amur Sturgeon and Huso huso, are the special product and important economic fish in Heilungkiang, are only distributed in
Heillongjiang River system.Wherein Amur Sturgeon is the native country sturgeon cultivation species of the earliest independent development of China, because which has individual big, growth
The advantages of fast and meat is good, and being welcome by raiser, accounts for more than the 15% of China's cultured output, but which has and is not easily accepted by
The shortcoming of man-made feeds.Huso huso build is very large, under the conditions of artificial cultivation growth vigor substantially, but its sexual maturity is later than other sturgeons
Fish, about 16-20, these cultivation shortcomings are subject to certain restrictions their cultivation, popularization.Heilungkiang hybrid sturgeon is black
Longjiang Huso huso and the filial generation of Amur Sturgeon, with the presence of a number of individual in the natural water area in Heilungkiang.From 2007
After the Heilungkiang hybrid sturgeon sexual maturity of year artificial cultivation, with other artificial sturgeon breeding variety protections, higher breeding is shown
Performance.And the cultivation experience of many raisers is also indicated that, the growth performance of Heilungkiang hybrid sturgeon is preferable.Therefore, Huso huso raun
There is important grinding with the Amur Sturgeon milter hybrid new breed production of hybrid seeds and seed rearing to the sound development for promoting China's Acipenser Sinensis industry
Study carefully meaning.
Content of the invention
It is an object of the invention to provide a kind of Huso huso raun and Amur Sturgeon milter hybrid breeding method, the method can be cultivated
Acipenser Sinensis new varieties and realize scale seed breeding.High through the hybrid seedlings insemination rate of the method cultivation, incubation rate.
The purpose of the present invention is achieved through the following technical solutions:
A kind of Huso huso raun and Amur Sturgeon milter hybrid breeding method, including:First, Juvenile stage, two, parent fish rearing and
Genital regulating, three, artificial fertilization and hatching, four, larva and juvenile and juvenile fish are cultivated, and are comprised the following steps that:
First, Juvenile stage:Female parent selects 14+Age Huso huso, male parent select 8+Age Amur Sturgeon.
2nd, parent fish rearing and genital regulating:By temperature control and fortification, promote male and female parent fish sexual maturity synchronization, specifically
Require as follows:
1st, parent fish is preferred:Select form, body colour normal, individual big, healthy without the female fish parent fish of 14 Huso husos more than age of wound,
Total length is up to 190~220cm, 60~90kg of body weight;Amur Sturgeon milter up to 8 more than age, 155~175cm of total length, body weight up to 18~
23kg;Preferred parent fish is put in 4 × 25m parent fish rearings pond in batches, male and female quantitative proportion is ♀: ♂=1: 1~1.5;Raise
20~25kg/m of density3;
2nd, parent fish feeding and fortification are cultivated:The feeding of parent fish:Bait is Acipenser Sinensis parent fish expanded pellet diet, feeds day 2 times,
0.5~1wt.% of the day feeding volume for fish body body weight;Parent fish fortification is cultivated:Primiparity sturgeon parent fish and send out through producing sturgeon parent fish gonad
When educating to IV, parent fish fortification cultivation is proceeded by, cultivated before incubating to parent fish product, gonad development is to the V phases;Through producing parent fish, produce
Feedstuff is fed after incubating, and is fed daily 2 times, 1~1.5wt.% of the feeding volume for parent fish body weight, bait:In per kilogram basis bait
Add the chilled fishes of 20wt.% and 3wt.% celluloses in material;
3rd, water temperature genital regulating:When natural temperature is down to 3 DEG C, 3 DEG C of water temperatures 50d are maintained;Then water temperature starts back from 3 DEG C
Rise, daily 1 DEG C of slow rising, until when being increased to 15 ± 0.5 DEG C, hereafter water temperature remains unchanged, routine observation parent fish gonad is sent out
Educate situation;
4th, breeding condition and daily management:Continuous charge, running water technology, the clear pond of timing change water;Condition of water quality:DO≥
6.0mg/L, pH7.0~8.0, hardness 10.0mg/l;Residual bait, blowdown are removed in time.
3rd, artificial fertilization and hatching:Crowded ovum, semen collection → artificial fertilization → wash ovum → incubating oosperm, wherein:Manually receive
Essence, fertilization rate reached to 90%;Hatching water temperature (15 ± 0.5) DEG C, hatches prelarva, incubation rate more than 85% after germ cell 168h.
4th, larva and juvenile and juvenile fish are cultivated:Feedstuff series are water silk earthworm → water silk earthworm+mixed feed → mixed feed.Membrane
1~7 sky and water silk earthworm live bait of prelarva is cultivated 7 after mincing, and cultivates water temperature (18 ± 0.5) DEG C, feeds number of times day for 8 times;Every after 7 days
Secondary when feeding, mixed feed need to be added in 5~7.5wt.% ratios in water silk earthworm and carry out mixing feeding, stop adding after 3 days
Mixed feed, changing live bait and replacing the mode of feeding with mixed bait carries out prelarva acclimatization culture, start to feed daily cooperation number of times 1~
2 times, live bait 6~7 times reduced by a live bait later and feeds number of times per 1~2 day, and the corresponding mixed feed that increases feeds number of times work, protects
Hold feed day sum constant;Through the mixed feed acclimatization culture of prelarva can be completed within 7~10 days.The hybrid sturgeon Seedling that this method is cultivated
Kind of rate of fertilization, incubation rate height (insemination rate reaches more than 90%, and incubation rate reaches more than 85%), and have that growth is fast, adaptability
Extensively, the characteristics of growth traitss such as strong stress resistance are excellent, is suitable for the cultivation of China different regions Acipenser Sinensis.
