Abstract
A kind of method of flowing water culture sturgeon, belong to the cultural method technical field of sturgeon, flowing water culture method of the sturgeon body weight in the 200g 1500g stages is referred specifically to, it includes the methods such as culturing pool, point pool cultivated, flowing water speed, dissolved oxygen amount, breeding density, feedstuff feeding method and specific aim feed；Its advantage is that culturing pool can bring oxygen into using double water inlets and double-drainage mechanism while water inlet, suitably increases dissolved oxygen amount, in draining along the dirt with discharge pond face and bottom of pond water can be made to keep cleaning；By sturgeon point size cultivation, yield can be improved to greatest extent using appropriate rate of water exchange, dissolved oxygen amount and cultivation density；Using rate, and oxygenation and progress conditioned reflex training before feeding is thrown is fed appropriate day, sturgeon can be made to form rule of life, accelerate to grow；Sweet wormwood powder is added in feed, the resistance against diseases of sturgeon can be increased, medicine is reduced and uses；Serial of methods can effectively improve yield, increase economic benefit.
Description
Technical field
The present invention relates to the cultural method technical field of sturgeon, particularly a kind of method of flowing water culture sturgeon.
Background technology
Sturgeon have it is high it is edible, medicinal, view and admire and economic value.Sturgeon other parts in addition to body surface hone lamella are all edible
With nutritive value is high, is listed in high tonic.Sturgeon promotes brain development to softening cardiovascular and cerebrovascular, improves IQ, in advance
Anti- senile dementia has good effect；Cartilage and marrow contain anticancer factor, there is saying for " shark fin, sturgeon bone "；Therefore
Sturgeon has high medical value again.
Sturgeon belongs to cold water fishes, and fast growth is Fresh ＆ Tender in Texture, be better economic result special aquatic products product it
One.There is cultivation in many areas in the whole nation.Although conventional cultural technique comparative maturity, in each stage grown in sturgeon, have
Different physiological requirements, more preferable culture efficiency can be reached by carrying out cultivation according to its physiological requirement.
The content of the invention
The present invention is according to sturgeon body weight by sturgeon point juvenile fish stage cultivation, and its segmentation method is：Below 100g is fry,
100-1500g is juvenile fish, and more than 1000g is adult fish.
Present invention solves the technical problem that be according to the growth characteristic of sturgeon there is provided a kind of sturgeon juvenile fish stage flowing water
Cultural method, to accelerate the growth quality and the speed of growth of sturgeon, increases economic efficiency.
In order to solve the above technical problems, the technical solution adopted in the present invention is a kind of method of flowing water culture sturgeon, bag
Flowing water culture of the sturgeon in juvenile fish stage is included, the juvenile fish stage refers to stage of the sturgeon body weight in 100g-1000g, its feature
It is to include following seven aspects：
(1) culturing pool uses the water intake mechanism of double water inlets and double-drainage mechanism, i.e. culturing pool to enter water dispenser with including upper water intake mechanism
Structure, drainage mechanism includes upper drainage mechanism and lower drainage mechanism；The upper water intake mechanism be set above pond body enter water dispenser
Structure, flowing water is vacantly wandered into pond body above water, is easy to bring into the oxygen in air；The lower water intake mechanism is in pond body
Being close to the water intake mechanism of bottom of pond face position setting on front side wall, being used during for impacting cleaning bottom of pond, be easy to coordinate bottom of pond draining
The dirt of device discharge bottom of pond deposition；The upper drainage mechanism is the top layer overfall set in pond body rear wall upper end, is used for
Discharge sewage floating on water；Lower drainage mechanism is the drainage arrangement set on the bottom of pond face of pond body, while water draining is changed
Reach the purpose of discharge bottom of pond dirt.
The culturing pool uses the width and the width phase of pond body of the water inlet in square cement culturing pool, lower water intake mechanism
Deng.
Pond the depth 110-130cm, depth of water 80-100cm of the culturing pool.
Discharge outlet in the drainage arrangement is arranged on bottom of pond face, the pool wall bottom without being provided in culturing pool, is supported
Grow the water in pond to discharge vertically downward first, be then discharged in steering in irrigation canals and ditches；So be easy to be deposited on bottom of pond bait and
Excreta is smoothly discharged with draining.
(2) the sturgeon of juvenile fish stage is pool cultivated according to different weight point, monomer body weight is respectively a heavy duty 100-
200g, two heavy duty 200-350g, three heavy duty 350-550g, four heavy duty 550-800g, five heavy duty 800-1100g, sixfold level 1100-
1500g totally six grades of culturing pools.
(3) flowing water speed, is defined up to 6-8 times by the daily flowing water exchange capacity of each culturing pool, determines flowing water inlet and outlet
Speed.
(4) the dissolved oxygen amount of water body is set to 7-10mg/L in culturing pool；When the dissolved oxygen amount in flowing water is less than 7mg/L, use
Oxygen-increasing device oxygenation.
(5) breeding density is set to per cubic meter of water and puts 20-25kg in a suitable place to breed.
(6) feedstuff feeding：It is 1.8%-2.2%, three heavy duties and four heavy duties that day in one heavy duty and two heavy duty culturing pools, which throws feeding rate,
Day in culturing pool throws feeding rate for 1.35%-1.65%, and the feeding rate of throwing day in five heavy duties and sixfold level culturing pool is 0.9%-1.1%.
(7) feeding method：Daily each throw sooner or later is raised once, is thrown when raising in the morning or the outer natural lighting intensity of evening culturing pool
Throwing feeding is carried out during for 5-20lux；The oxygenation into culturing pool before raising is thrown, the dissolved oxygen amount in water body is reached 9-10mg/L；When throwing feeding
Turning on light within 6-8 minutes in advance makes pond face intensity of illumination reach 30-50lux, then carries out throwing feeding, and forming rule forms cultivation fish
The conditioned reflex entered before raising.
The feed uses sturgeon growth period feed, and the sturgeon growth period feed is by fish meal 57-63 according to parts by weight
Part, 19-21 parts of alphalise starch, 4.7-5.3 parts of wheat flour, 4.7-5.3 parts of soya-bean cake, 2.8-3.2 parts of fish oil, 0.47-0.53 parts of hepar siccatum,
0.47-0.53 parts of sweet wormwood powder is mixed.
Oxygen can be brought into while water inlet using double water inlets and double-drainage mechanism the beneficial effects of the invention are as follows culturing pool
Gas, suitably increases dissolved oxygen amount, in draining along the dirt with discharge pond face and bottom of pond water can be made to keep cleaning；By sturgeon point
Size is cultivated, and diet can be avoided unbalanced, can be carried to greatest extent using appropriate rate of water exchange, dissolved oxygen amount and cultivation density
High yield；Using rate, and oxygenation and progress conditioned reflex training before feeding is thrown is fed appropriate day, sturgeon can be made to form life
Rule, accelerates growth；Sweet wormwood powder is added in feed, the resistance against diseases of sturgeon can be increased, medicine is reduced and uses；A series of sides
Method can effectively improve yield, increase economic benefit.
