Abstract
The invention discloses a kind of fish oosperm collection method, comprise the following steps：1) by one there is the collecting net one end that can intercept fish oosperm to hang and expose to a collection waters；The upper end of collecting net has water inlet, and lower end has collection port, collection port connection collecting chamber；2) water inlet of collecting net is connected with the waters of spawning, and the current direction in spawning waters is collected waters；3) after collecting a certain amount of embryonated egg, collecting net is taken out；4) remove collecting chamber and take out embryonated egg collected in collecting chamber.The present invention is easy to operate, and is difficult to produce injury to fish-egg and fry.
Description
Technical field
The present invention relates to a kind of method for collecting fish oosperm.
Background technology
The ovum that many fishes are produced is floatability, collects floating fish-egg in artificial waters or natural water area and generally adopts
Fished for net, or collected in an overfall.This will cause the mechanicalness injury of embryonated egg or juvenile fish,
So as to reduce incubation rate and the survival rate of seedling reduction of embryonated egg, the spawning process of fish can be also influenceed.The opposing party
Face, existing collection device volume is big, not easy to operate.
Therefore those skilled in the art are devoted to a kind of method for being easy to collect fish oosperm of exploitation.
The content of the invention
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide one kind and are easy to
The method for collecting fish oosperm.
To achieve the above object, the invention provides a kind of fish oosperm collection method, comprise the following steps：
1) by one there is the collecting net one end that can intercept fish oosperm to hang and expose to a collection waters；Collecting net
Upper end there is water inlet, lower end has collection port, collection port connection collecting chamber；2) by the water inlet of collecting net
Mouth is connected with the waters of spawning, and the current direction in spawning waters is collected waters；3) a certain amount of fertilization is collected
After ovum, collecting net is taken out；4) remove collecting chamber and take out embryonated egg collected in collecting chamber.
The beneficial effects of the invention are as follows：The present invention is easy to operate, and is difficult to produce injury to fish-egg and fry.
Brief description of the drawings
Fig. 1 is the structural representation of the device that the embodiment of the invention is used.
Fig. 2 is the structural representation that the present invention uses collecting frame in device.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
A kind of fish oosperm collection method, comprises the following steps：
1) by one there is the collecting net one end that can intercept fish oosperm to hang and expose to a collection waters；Receive
Collecting the upper end of net has water inlet, and lower end has collection port, collection port connection collecting chamber；
2) water inlet of collecting net is connected with the waters of spawning, and the current direction in spawning waters is collected waters；
3) after collecting a certain amount of embryonated egg, collecting net is taken out；
4) remove collecting chamber and take out embryonated egg collected in collecting chamber.
As depicted in figs. 1 and 2, above-mentioned collection method can be realized by a kind of fish oosperm collection system,
The system includes being provided with collecting frame 14 in collecting box 13, collecting box 13；Collection is placed with collecting frame 14
Net 12；The lower openings 24 of collecting net 12 are connected with collecting chamber 26.
The top of collecting net 12 is connected with lifting rope 15；Lifting rope 15 bypasses fixed pulley 16.
The top of collecting net 12 is provided with water inlet 22；The bottom of collecting box is provided with delivery port 34；Water inlet
Mouth 22 and delivery port 34 are connected with spawning groove 17 by pipeline.
Fish-egg is flowed into collecting net 12 from water inlet 22,32, and collecting net 12 is stored in through the filtering of collecting net 12
On.Be collected into it is a certain amount of after, move the end of rope 15 to, so as to collecting net 12 of slinging, collect embryonated egg.
Preferred embodiment of the invention described in detail above.It should be appreciated that the ordinary skill of this area
Personnel just can make many modifications and variations without creative work with design of the invention.Therefore, it is all
Technical staff passes through logic analysis, pushes away on the basis of existing technology under this invention's idea in the art
Reason or the available technical scheme of limited experiment, all should be in the protection model being defined in the patent claims
In enclosing.
