Description
Technical field
Fish culture field is the utility model is related to, is specifically related to a kind of fish recapture netting gear.
Background technology
Parent population generally requires to be carried out injection to hasten parturition in breeding process, then needs to rest before carrying out injection and hastening parturition
The parent population recapture in the pool is grown in order to manually carry out injection operation.Existing recapture method is：Selection one side is drawn in the net, two drawn in the net
End is pulled by manpower traction respectively, draw in the net it is middle specially step on bottom line by two people, and to draw in the net by culture pond side slowly
Opposite side is moved to concentrate parent population to realize.The shortcomings that recapture method, is：The moving resistance drawn in the net is big, and both ends also need to
Eight to ten people are had an effect simultaneously, and dragging is drawn in the net, it is necessary to consume a large amount of manpowers, and labor intensity is big；In addition, after parent population is concentrated, cause to support
It is big to grow density, the easy water shortage anoxic of fish is injured or dead so as to cause.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of fish recapture netting gear.People is saved in netting gear fishing
Work, labor intensity is reduced, fish will not be caused to damage substantially in addition.
To achieve the above object, the utility model employs following technical scheme：
A kind of fish recapture netting gear, including the purse seine for drawing in the net and collecting fish of fish is caught up with, the purse seine is arranged on culture pond
Interior side and spacing is reserved between culture pond bank, the purse seine bottom is connected with spacer screen, the purse seine side be provided with into
Lymphogranuloma inguinale, the fish inlet left side are extended with the first block being vertically arranged to purse seine outside, and the fish inlet right side is to outside purse seine
Side is extended with the second block being vertically arranged, and first block, the second block are formed into fish passage, it is described enter fish passage width
Degree is gradually reduced towards fish inlet direction and is in splayed, and the first block interception nearer apart from the culture pond bank is set
Put between the purse seine and culture pond bank；It is described to draw in the net to be located at and one end outer into fish passage with fish inlet right side admittedly
Fixed, the other end that draws in the net extends to culture pond bank and forms the drawing end moved along culture pond periphery.
Further, the top edge interval of drawing in the net is fixed with multiple floats, and the lower edge that draws in the net is fixed with iron chains structure
Into sinker, the iron chains length and the lower edge equal length of drawing in the net.
Further, the purse seine lateral surface is interval with multiple vertical supporting bars, and the purse seine top edge erects with described
Fixed to support bar.
Further, the left side of the fish inlet is extended with the 3rd block into purse seine, and the right side of the fish inlet is to enclosing
The 4th block is extended with net, the 3rd block, the 4th block are arranged to prevent fish run out of from enclosing after fish enter purse seine
The closing in shape of net.
Further, the support bar is adjustable for height telescopic structure.
The beneficial effect of above-mentioned technical proposal is mainly reflected in the following aspects：
(1) the utility model only needs to arrange people to be operated drawing in the net one end when in use, for example two people draw
Drag the drawing end so that the drawing end, which is moved and gradually tightened up along culture pond bank, draws in the net, while causes fish in culture pond
Opposite side and entering is rushed to by side realized in purse seine and collected, the people of labor intensity and input when substantially reducing recapture
Power.After fish is caught up with purse seine, lifting purse seine can be caught, and purse seine can be also used for temporarily supporting to avoid parent population anoxic, increase
Operable time.
It is described enter fish passage be easy to fish smoothly to enter inside purse seine, it can in addition contain avoid being rushed to fish at fish inlet from
Escaped in spacing between purse seine and culture pond bank.
Without fish all to be concentrated on to culture pond side during the utility model recapture fish, it is only necessary to by drawing in the net that number will be met
The fish that amount requires is caught up with into purse seine, small to parent population degree of injury, and the whole parent population of fishing will not be dehydrated, and will not make substantially
Damaged into parent population, fishing is convenient, and the operating time is flexible.
(2) it is described in the utility model to draw in the net to be vertically arranged below the culture pond water surface by the effect of float, sinker.Institute
Stating the sinker of iron chains composition can prevent recapture fish slips through the net from escaping so that drawing in the net lower edge sinks to culture pond bottom.
(3) the 3rd block described in the utility model, the 4th block can block the fish inlet after fish enters purse seine,
To prevent the fish collected from escaping from again.The utility model is simple in construction, easy to use.
(4) support bar is telescopic structure, and such support bar can drive the purse seine to carry out oscilaltion movement,
The purse seine is raised above that operation of fishing with a net can be carried out with personnel easy to operation.
