Description
Technical field
The present invention relates to a kind of pomfret ovum collecting circulator and application method avoided damage to, and it is pool cultivated to belong to cultivation
Silvery pomfret artificial propagation techniques field.
Background technology
Silvery pomfret is one of main marine products economic fish in China, and delicious meat has higher nutritive value and market
Demand, but in recent years, due to overfishing and environmental degradation, has there is the mark that significantly fails in China's wild pomfret germ plasm resource
As therefore, studies in China scholar starts to carry out the artificial breeding work of silvery pomfret successively.The bottleneck of artificial propagation has been broken through at present.
But since artificial breeding starts late, lacks experience, the laying season of annual late March to early June needs to expend a large amount of artificial
Fish-egg is collected with energy, since silvery pomfret fish-egg belongs to buoyant egg, when oviposition, needs artificial trawlnet or drags for ovum in pool side netting gear,
Seedling cost is high, and inevitable etting can cause to damage to fish-egg, cause a large amount of fish-eggs to be wasted, rate of fertilization is low, hatching rate
It is low.Therefore, in order to improve fish-egg collection efficiency, the artificial input of saving reduces production cost, reduces the damage of fish-egg and parent population,
It is necessary to invent a kind of to avoid, using netting gear and simple and practicable fish-egg collection device, improving production process and being unfavorable for seed breeding
The phenomenon that.

For water outlet II (42).
5. the apparatus according to claim 1, it is characterised in that：It is described that integrate ovum bucket (5) white as plastics made of PVC material
Bucket, 1500 liters of volume, 1.6 meters of back cut diameter, 1.4 meters of base diameter, bucket are 1.2 meters high.
6. the apparatus according to claim 1, it is characterised in that：The collection ovum bucket (5), liquid outlet and water discharging valve
Diameter 5cm.
7. the apparatus according to claim 1, it is characterised in that：10 meters described of water pump (6) lift；The return duct (7) stated
For black silica gel hose, long 5cm, bore 5cm.
8. making and the application method of claim 1-7 any one of them devices, which is characterized in that include the following steps：
(1) remaining tube body after a part of tube body is cut away as collecting ovum using a hollow cylindrical tube is longitudinally perforative
Pipe；After the drainpipe top of spawning pond middle position separately sets the connector of same shape, by one end of ovum collector and connection
Mouth is attached, and interface is fixed with adhesive waterproof tape, notices that the longitudinal incision of ovum collector is upwards and parallel with horizontal plane, really
Thus protecting the fish-egg of floating on water can enter；
(2) when normal cultivation, the discharge outlet of the bottom of pond of spawning pond is connected with the end of drainpipe upwards, is also connected with one downwards and goes out
Water pipe, outlet pipe main body are a transverse tube being laterally arranged, and the both ends of transverse tube are respectively vertically equipped with a vertical tube；Piece vertical tube
End is connected with discharge outlet, and the end of another vertical tube connects a dismountable pipe and used as waste liquid is excluded, on transverse tube
It is provided with flowing water Valve, opening flowing water Valve can then be drained；
(3) if necessary to collect fish-egg, then inlet, a symmetrical side lower part are separately set in a upper lateral part of collection ovum bucket bucket wall
Liquid outlet is separately set, liquid outlet is equipped with water discharging valve；Will two orthogonal, be arranged after the connection of the pvc pipes that one is long and the other is short and
At tube body as conduit；By dismountable pipe remove after, then by the end of long tube with exclude waste liquid vertical tube end
The end of connection, short tube is inserted into the inlet of collection ovum bucket；The import of water pump is connected with water discharging valve；By the outlet of water pump
It is connected with return duct, spawning pond is stretched into the end of return duct；It can be fixed with clip when connection；
It needs to turn off gas stone when collecting fish-egg, appropriate oviposition water is packed into collecting ovum bucket, prevents fish-egg from falling from above and making
At damage；Flowing water Valve is opened, since spawning pond and formation liquid level in drainpipe are poor, and silvery pomfret is buoyant egg, the fish-egg of output
It can swim on the water surface；Therefore, the fish-egg of the water surface can be entered by ovum collector in the drainpipe in spawning pond center with flow,
And finally enter in collection ovum bucket with flow；Fish-egg in ovum bucket to be collected increases, with water pump from the drain valves of another side bottom
It is middle to extract extra water out, and be conveyed back in spawning pond by return duct, and water (flow) direction and ovum collector notch are opened
Fish-egg is constantly transported in ovum collector on the contrary, flow will be recycled by specific direction by mouthful direction.
