Abstract
The invention discloses a kind of sturgeon artificial propagation tank and propagation method, belong to fish culture field；Technical problem to be solved, which there is provided one kind, can control temperature in real time, ensure the artificial propagation device and propagation method of sturgeon laying quality；Solve technical scheme that the technical problem uses for：A kind of sturgeon artificial propagation tank, water inlet pipe and outlet pipe are provided with breeding tank, bottom sets blow-off pipe, inside injection liquid oxygen, temperature sensing device is provided with tank and measures water temperature in real time, selection parent population is cultivated more than 1 month in 10 DEG C of cultivation tank, and parent population is transferred to 12 ~ 13 DEG C of hatchery, oxytocins is used to parent population, collecting semen, ovum grain is taken, carries out artificial insemination, artificial incubation；It the composite can be widely applied to fish culture field.
Description
Technical field
A kind of sturgeon artificial propagation tank of the present invention and propagation method, belong to fish culture technical field.
Background technology
In the industrial aquaculture of sturgeon, water temperature is to cultivate the most important environmental factor of sturgeon parent population, and it cultivates suitable water temperature
It is 4 ~ 10 DEG C, therefore sturgeon is cultivated in 15 DEG C of water temperature is continued above, parent population sexual gland can grow, but not reach maturation,
Can not normally it ovulate, it is also abnormal ovum even to discharge ovum, and rate of fertilization, hair eye rate are all very low, therefore the physiological maturity of sturgeon will
Ask antenatal and be no less than bimestrial low temperature stimulation, general low temperature is 4 ~ 6 DEG C, existing sturgeon artificial cultivating method, Wu Fayou
The temperature of the regulation and control sturgeon physiological requirements of effect, it is difficult to ensure the spawning rate of sturgeon, cannot guarantee that the qualified of sturgeon spawning, it is impossible to
Meet the needs in market.
The content of the invention
The invention overcomes the deficiencies of the prior art, and provides one kind can control temperature, guarantee sturgeon production in real time
The artificial propagation device and propagation method of archiblast amount.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of sturgeon artificial propagation tank, its feature
It is：Tank is bred, breeding tank top is provided with water inlet pipe, and bottom is provided with outlet pipe, and bottom is provided with sewage draining exit, and outer surface is set
Heat-insulation layer is equipped with, is internally provided with cooling tube and temperature sensing device.
Refrigerant used in described cooling tube is liquid oxygen.
Described breeding pot bottom is pot bottom-shape, and the circumferential bottom of pond concavity of tank bottom four tilts, and the sewage outfalls setting exists
Tank bottom center.
A kind of sturgeon artificial fecundation method, comprises the following steps：
（1）The previous moon is produced in sturgeon mating period, selects belly enlargement and soft flexible, more than 3 μm of ovum diameter, in ellipse
Circle, celadon or blackish green, both ends differentiation is obvious, and thing the raun of the lacklustre spot of white extremely occurs as parent population；Select
Body back of the body afterbody ventrad bending is in " bow " shape, and gonopore is gently pressed with hand, has the milter of a little seminal fluid outflow as parent population；
（2）Parent population is put into the breeding tank that water temperature is 10 DEG C or so and cultivated, parent population is transferred to water temperature as 12 ~ 13 DEG C after 1 month
Hatchery in；
（3）Using promoting the sexual maturity, medicine is hastened parturition to parent population, and the parent population through hastening parturition temporarily is supported respectively, stimulation by running water；
（4）Collecting semen, ovum grain is taken, with semidry method artificial insemination；
（5）Incubating oosperm is carried out in the incubator that 16 ~ 24 DEG C of water temperature, ovum stir；
（6）Nursery pond is transferred to the seed after hatching to cultivate.
The present invention has the advantages that compared with prior art.
1st, tank reclaimed water is cooled by injecting liquid oxygen in tank is bred, temperature in use meter measures in real time, Ke Yishi
Now to the grasp of breeding tank temperature, liquid oxygen is injected to culture pond when temperature is high, stops injection work when temperature is low.
2nd, breeding tank is provided with water inlet pipe and outlet pipe, it is ensured that parent population in the environment in running water, ensure that all the time
The survival rate of parent population.
3rd, breeding tank outer surface is provided with insulation material, can preferably keep the temperature in tank, promote parent population into
Ripe rate.
