Abstract
The utility model relates to a kind of mesh sheet can draw type drift artificial fish-aggregating device in, belongs to fishery basis facility field.A kind of mesh sheet can draw type drift artificial fish-aggregating device in, and comprise and floating in the buoyancy aid of the water surface, the positioning buoy that is arranged at the mesh sheet below buoyancy aid and is connected with buoyancy aid, the both sides of described mesh sheet are arranged with two row's frenulums.The utility model, when the intensive marine site of shark green turtle or season attract to lure thermal-arrest band Tuna--like Fishes, draws mesh sheet in by frenulum, can significantly reduce the bycatch such as shark, green turtle while attraction tuna.
Description
Technical field
The utility model belongs to fishery basis facility field, and particularly a kind of mesh sheet can draw type drift artificial fish-aggregating device in.
Background technology
Tuna--like Fishes (particularly stripped tuna, yellowfin tuna and less big-eye tunas) has the behavioral trait around drifts such as being gathered in natural driftwood (trunk, branch, leaf etc.) or mankind's abandon (plank, metal bucket etc.).In the past thirty years, fisherman utilizes this behavioral trait of tuna, develop drift artificial fish-aggregating device, assemble the shoal of fish at Tropical Ocean Area and fished for, nowadays the catch of this operating type has accounted for over half in the gross yield of purse seine fishery.
But existing drift artificial fish-aggregating device is not only attractive to Tuna--like Fishes, also can attract other pelagic fishes simultaneously.Special in some specific marine site and seasons, use drift artificial fish-aggregating device doublely in a large number can catch the protection such as shark and green turtle fingerling, affect the balance of the ecosystem at the middle and upper levels.
Utility model content
The purpose of this utility model is for the problems referred to above, provides the drift artificial fish-aggregating device that a kind of mesh sheet can draw type in, has both reduced the attraction to non-targeted fingerlings such as sharks, facilitates again and drags for the collecting that lures of Tuna--like Fishes.
The purpose of this utility model is achieved in that
A kind of mesh sheet can draw type drift artificial fish-aggregating device in, and comprise and floating in the buoyancy aid of the water surface, the positioning buoy that is arranged at the mesh sheet below buoyancy aid and is connected with buoyancy aid, it is characterized in that, the both sides of described mesh sheet are arranged with two row's frenulums.
Wherein, described row's frenulum has button hole, and another row's frenulum is provided with button.
Wherein, described buoyancy aid is made up of some ball floats be together in series.
Wherein, described positioning buoy is built with GPS positioner.
The beneficial effects of the utility model are: in the more marine site of bycatch or when using season, mesh sheet drawn in, can reduce the attraction to non-targeted fingerlings such as sharks, can take into account gathering Tuna--like Fishes again by frenulum.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Embodiment
Below in conjunction with specific embodiments and the drawings, set forth the utility model further.
As shown in Figure 1, a kind of mesh sheet can draw type drift artificial fish-aggregating device in, and comprise and floating in the buoyancy aid 1 of the water surface, the positioning buoy 3 that is arranged at the mesh sheet 2 below buoyancy aid 1 and is connected with buoyancy aid 1, the both sides of described mesh sheet 2 are arranged with two row's frenulums 4.When this device is in the less marine site of bycatch or when using season, mesh sheet 2 is launched to put into water, to reach the best effects attracting tuna; And in the more marine site of bycatch or when using season, put into water after mesh sheet 2 can being drawn in frenulum 4, the attraction to non-targeted fingerlings such as sharks can be reduced, gathering Tuna--like Fishes can be taken into account again.
One row's frenulum 4 has button hole 5, and another row's frenulum 4 is provided with button 6.Compare and directly mesh sheet 4 fastened by frenulum 4, stability is higher, and the situation that can prevent mesh sheet 4 from launching because tying loosens in water occurs.
Buoyancy aid 1 is specifically made up of some ball floats be together in series.When this device is placed on fishing boat, can overallly draw in, institute takes up space less.
In buoy 3, GPS positioner is also housed, so that fisherman finds the particular location of the drift artificial fish-aggregating device that location oneself is thrown in boundless sea.
Claims (4)
1. a mesh sheet can draw type drift artificial fish-aggregating device in, comprise and float in the buoyancy aid (1) of the water surface, the mesh sheet (2) being arranged at buoyancy aid (1) below and the positioning buoy (3) be connected with buoyancy aid (1), it is characterized in that, the both sides of described mesh sheet (2) are arranged with two row's frenulums (4).
2. mesh sheet according to claim 1 can draw type drift artificial fish-aggregating device in, it is characterized in that, described row's frenulum (4) has button hole (5), and another row's frenulum (4) is provided with button (6).
3. mesh sheet according to claim 1 can draw type drift artificial fish-aggregating device in, it is characterized in that, described buoyancy aid (1) is made up of some ball floats be together in series.
4. mesh sheet according to claim 1 can draw type drift artificial fish-aggregating device in, it is characterized in that, described positioning buoy (3) is built with GPS positioner.
