Description
Technical field
It the utility model is related to Technique in Fishes cultivation field, more particularly to a kind of fish parent population traction fixing device.
Background technology
Parent population, refers to development and arrives the sexal maturity stage, the milter or raun for having fertility, also cry kind of a fish.With aquatic products industry
Progressive, aquatic products kind develops towards name, spy, excellent direction.Famous-particular-excellent fish are since its nutritive value is high, delicious flavour Er Shenshou cities
Field favor, famous-particular-excellent fish culture is in the ascendant, large-scale famous-particular-excellent fish culture, be unable to do without a large amount of seeds, and seed is obtained
Natural fishing must be only relied on and be obviously unable to meet demand, the source for propagating seed artificially relies primarily on artificial propagation.Existing people
Work breeding is mainly grabbed fish and the belly of parent population is extruded using dredger or towel, gathers the essence and ovum of parent population, through shape of being fertilized
Into embryonated egg, so as to obtain the seed of high-quality fish.
The shortcomings that prior art, is：Mucus is distributed with fish surface, when power kicks the beam when manually grasping, be easy to cause and grabs
Hold loosely, parent population is slid on ground, influences extruding efficiency；When manually grasping power is overweight, fish body is hurt, causes parent population dead
Die, other purposes can not be carried out.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of oxygenation effect preferably and oxygenation scope is big supports
The oxygen increasing equipment grown.
Technical solution is used by the utility model solves above-mentioned technical problem：Fish parent population traction fixing device, bag
Preceding screen cloth and rear screen cloth are included, the accommodation space of parent population can be placed by being formed between preceding screen cloth and rear screen cloth, preceding screen cloth and rear screen cloth
Lower edge is connected, it is characterised in that the side of preceding screen cloth and rear screen cloth is opened wide, and the opposite side of preceding screen cloth and rear screen cloth is provided with half
Lateral edges are opened wide, half lower part for opening wide lateral edges is the closure of suture, and half top for opening wide lateral edges is unlimited opening and closing part.
The further preferred scheme of the utility model is:The closure occupies half and opens wide lateral edges 2/3rds, described
Opening and closing part occupy half and open wide lateral edges 1/3rd.
The further preferred scheme of the utility model is:The preceding screen cloth and the upper end of rear screen cloth are interspersed with strip
Clamping piece.
The further preferred scheme of the utility model is:The clamping piece is cylinder or cuboid.
The further preferred scheme of the utility model is:The angle that described half is opened wide on lateral edges and vertical direction is in 30
Degree, half opens wide the auxiliary fixed cavity for being formed between lateral edges, preceding screen cloth and rear screen cloth and being used for fixing parent population.
The further preferred scheme of the utility model is:The preceding screen cloth and rear screen cloth are integrally formed.
The further preferred scheme of the utility model is:The closure is arc-shaped, and the fish head of parent population is fixed on closure
Between neighbouring preceding screen cloth and rear screen cloth.
The further preferred scheme of the utility model is:The one side edge that the preceding screen cloth opens wide is preceding open edge, after
The one side edge that screen cloth opens wide is rear open edge, and preceding open edge and rear open edge are perpendicular to the lower edge.
The further preferred scheme of the utility model is:The preceding screen cloth and rear screen cloth are made of fishing net cloth.
Compared with prior art, the utility model is opened wide by the side of preceding screen cloth and rear screen cloth, preceding screen cloth and rear screen cloth
Opposite side be provided with half and open wide lateral edges, half closure for opening wide lateral edges is used for the head for fixing parent population, and half opens wide side
The opened portion of edge is used for the head for aiding in fixed parent population so that parent population is fixed more smooth；In use, preceding screen cloth and rear screen cloth bag
Wrap parent population and extrude so that ovum, essence are flowed out out of parent population body.
