Abstract
The technical solution of the utility model is, a kind of fry tempers net cage, it is characterized in that, net cage body is trapezoidal net cage, net cage B hold net cage wall energy be enough put into net cage bottom same plane, become net cage extend floppa, hold between both sides net cage wall and floppa at net cage B, wing lattice is set; When using this net cage, the net cage wall that the net cage B of net cage body holds is set level, floppa is stretched, summer flower fry is drawn in the net to rush in net cage body by the closing in of wing lattice, reel wing lattice, the floppa that net cage B is held erects, become net cage wall, summer flower fry gathers in trapezoidal net cage, because net cage A holds narrower, be beneficial to the intensive exercise of summer flower fry, after exercise certain hour, decontrol floppa, fry is held in fast return water body from the net cage B that opening is larger, make exercise routine little on the impact of summer flower fry, fry physique is strong; The utility model is convenient to make, easy to use, respond well.
Description
Technical field
The utility model relates to fish production field, and specifically a kind of fry tempers net cage.
Background technology
Fry is the basis produced of breeding fish, carry out fish production, be unable to do without fry rearing, in fry rearing process, need repeatedly to draw in the net a point pool, especially fry is after cultivation to summer flower stage, point pool particular importance in this period, the life in water body environment has been adapted in fry rearing process, due to not through intensive, fry is extremely inadaptable to environmental change suddenly, usually produce stress reaction or dead because of anoxic, in order to the custom making summer flower fry adapt to intensive environment, summer flower fry is made to stand test in operation and handling process, summer flower fry go out the pool have to pass through repeatedly draw in the net take exercise, tradition use is drawn in the net after Direct stenting, fry exercise is carried out as net cage, summer flower fry is in net circle or when entering net cage, usually cause the choke-out of a large amount of summer flower fry, its reason is drawn in the net in traveling process, and it is large to draw in the net screen frequency, mesh is little, mesh is because water body dirt is gradually by after obturation, and inside and outside water body can not exchange, and fish body manure contamination water quality causes fry hypoxia death.
Summary of the invention
For overcoming above-mentioned defect, the utility model devises a kind of fry and tempers net cage.
The technical solution of the utility model is, a kind of fry tempers net cage, it is characterized in that, net cage body is trapezoidal net cage, and narrower one end is that net cage A holds, and wider one end is that net cage B holds, net cage B hold net cage wall energy be enough put into net cage bottom same plane, become the floppa that net cage extends, hold between both sides net cage wall and floppa at net cage B, wing lattice is set.
When using this net cage, the net cage wall that the net cage B of net cage body holds is set level, floppa is stretched, summer flower fry is drawn in the net to rush in net cage body by the closing in of wing lattice, reel wing lattice, the floppa that net cage B is held erects, become net cage wall, summer flower fry gathers in trapezoidal net cage, because net cage A holds narrower, be beneficial to the intensive exercise of summer flower fry, after exercise certain hour, decontrol floppa, fry is held in fast return water body from the net cage B that opening is larger, make exercise routine little on the impact of summer flower fry, fry physique is strong; The utility model is convenient to make, easy to use, respond well.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
In figure: 1 net cage A holds, 2 net cage bodies, 3 net cage B hold, 4 wing lattices, 5 floppas.
Embodiment
The utility model of accompanying drawings, a kind of fry tempers net cage, it is characterized in that, net cage body 2 is trapezoidal net cage, and narrower one end is that net cage A holds 1, and wider one end is that net cage B holds 3, net cage B hold 3 net cage wall energy be enough put into net cage bottom same plane, become the floppa 5 that net cage extends, hold between 3 both sides net cage walls and floppa 5 at net cage B, wing lattice 4 is set.
When using this net cage, the net cage wall of 3 is held to set level the net cage B of net cage body 2, floppa 5 is stretched, summer flower fry is drawn in the net to rush in net cage body 2 by the closing in of wing lattice 4, reel wing lattice 4, net cage B is made to hold the floppa 5 of 3 to erect, become net cage wall, summer flower fry gathers in trapezoidal net cage, because net cage A end 1 is narrower, be beneficial to the intensive exercise of summer flower fry, after exercise certain hour, decontrol floppa 5, fry is held in 3 fast return water bodys from the net cage B that opening is larger, make exercise routine little on the impact of summer flower fry, fry physique is strong; The utility model is convenient to make, easy to use, respond well.
