Description
Technical field
The present invention relates to technical field of aquaculture, in particular to the hatching apparatus of a kind of excellent fertilized eggs of round spot halibut and side
Method.
Background technique
Round spot halibut is mainly distributed on the north Coast of China's Huanghai Sea, the Bohai Sea and South Korea and Japan, for many years, has received
Degree fishing and environmental change influence, and the decline of natural resources, amount of fishing is reduced year by year, and natural resources is increasingly exhausted endangered.
Suitable growth water temperature is at 15 DEG C~23 DEG C, and suitable salinity range is 23~31.
The process of the embryonic development of dollar spot Scophthalmusmaximus ovum is as follows: when water temperature is (11 ± 0.5) DEG C, fertilized eggs last 153h
Demoulding is hatched, and prelarva passes through 6d initial feeding when water temperature is (15 ± 0.5) DEG C after hatching, and 50d completes abnormal into juvenile fish.
The ovum of round spot halibut is semibuoyant egg, and there are many yolk amount.Spilting of an egg later period, the size and cleavage rate of blastomere
There is difference.Upper eyelid occurs before segmentation.Just hatching prelarva alimentary canal is thin and straight, and hatching 5d anus is got through, and 6d is opened
Mouthful.With the disappearance of yolk bag, alimentary canal starts to be bent.Chromatophore primarily occur ins in the idiosome of 86h, until 140h is in yolk
It is sporadicly distributed on capsule, and with embryo development, chromatophore increases, until the densely covered black color spot of whole body after the completion of abnormal.Idiosome color
The shape of plain cell gradually becomes round by the flakes before hatching, but the chromatophore on yolk bag is always flakes.
The round spot halibut artificial breeding in China is hided to be cultivated in northern net cage whole year, and round spot halibut parents culture is by environmental factor
It influences greatly, mature parent and ovum sperm quantity of fine quality are few, ovum artificial collection, fertilization, the separation of superiority and inferiority matter ovum, incubating oosperm temperature
Many reasons such as the big technical requirements height of links difficulty such as low, time length, cause round spot halibut seed breeding difficulty very big, cultivation
Seed quantity is far from satisfying the market demand, to seriously constrain round spot halibut seed breeding and cultivation scale.It is above-mentioned each
In sport technique segment, round spot halibut high quality fertilized egg of scophthatmus hatching technique is key technique, which seriously affects round spot halibut seedling
Kind breeding, is a technical problem to be solved urgently.Conventional operation scheme on the market, the fish-egg being easy to damage in hatching or at
The fry of type, survival rate are lower.
Summary of the invention
The object of the present invention is to provide the hatching apparatus and method of a kind of excellent fertilized eggs of round spot halibut, have convenient for operation,
The high advantage of hatching rate.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of hatching apparatus of the excellent fertilized eggs of round spot halibut, including hatchery, the hatchery include cylindrical body, with
The conical staving that the end face of cylindrical body connects, the cylindrical body are configured with water inlet pipe and water filter, the circular cone
Shape staving is connected with sewage pipe away from one end of cylindrical body.
By using above-mentioned technical proposal, damage convenient and efficient in operation, to fish-egg is smaller, compares routine operation
Improve hatching survival rate.
Further, the cylindrical body is equipped with overflow pipe, and the overflow pipe protrudes into one end in column barrel body
It is covered with bolting silk net.
A kind of hatching method of the excellent fertilized eggs of round spot halibut, characterized by the following steps:
S1: nature seawater is injected into hatching apparatus to being full of inside container；
S2: by the lower water temperature of nature seawater between 10~15 DEG C；
S3: nature seawater is persistently heated；
S4: to continuous charge in nature seawater；
S5: continuous charge state is kept, while upper end water inlet pipe flowing water is adjusted to inner bucket water day exchange capacity in 20-30% model
In enclosing；
S6: round spot halibut fertilized eggs are added into nature seawater and prepare hatching；
S7: EM is added into nature seawater beneficial to bacterium solution；
S8: cut off the water 2 times a day, turn tolerance down；
S9: the daily dead ovum for taking out container bottom in time；
S10: to the heartbeat apparition, egg membrane reddens, and is clearly visible in egg membrane after prelarva fish shape, stops for observation fertilized eggs metamorphosis
Gas is cut off the water；
S11: it after fertilized eggs floating, moves it in hatchery.
Further, the salinity 30-33 ‰ of the nature seawater in hatching apparatus.
Further, the gradually stabilization of 0.3-0.5 DEG C to 15 DEG C of heating is maintained at daily to the amplitude of nature seawater heating
State.
Further, when inflating into nature seawater, tolerance is adjusted to air-flow and agitates seawater to make fertilized eggs in water from bottom
Subject to suspended state.
Further, the density of round spot halibut fertilized eggs is launched into nature seawater are as follows: every 2 kilograms/m3It is put into round spot star
Flounder fertilized eggs.
Further, EM beneficial bacterium hydraulic control day infusion volume 15-20ml/ days.
Further, the dead ovum in bucket bottom is sucked out with suction pipe.
Further, fertilized eggs are in hatchery according to 3000/m3Cloth ovum.
