Description
Technical field
The invention belongs to the fishing of aquaculture and fish field, specifically a kind of device for traping Rapana venosa and its
Method for entrapping.
Background technology
Rapana venosa Rapana venosa, " spinach spiral shell ", " conch " are commonly called as, belong to Mollusca, Gastropoda, Muricidae, it is red
Spiral shell category, high up to 11~12cm into body shell, China Bohai Sea and the Huanghai Sea are distributed.Rapana venosa foot is especially loose, delicious flavour,
Nutritious, very people institute eating, economic value are high.In the last few years, with Rapana venosa near-coastal resources decline and both at home and abroad
The situation of selling well in market, its economic value improve constantly, and live body price is 20~40 yuans/kilogram at present.
At present, Rapana venosa has the very big market demand in China Bohai Sea and Huanghai Sea bank, because artificial breeding technique does not have
Break through, realize industrialized scale far away, cause artificial farming not carry out on a large scale.Therefore, Rapana venosa is mainly derived from into spiral shell
Sea area fishes, but the less efficient, cost fished is big, far can not meet the needs of market.Rapana venosa is caused to be fished into spiral shell
The reason for efficiency is low is that Rapana venosa fishes mode.Up to now, the mode that fishes of Rapana venosa relies primarily on diver and enters pedestrian
Power fishes, or is obtained when reclaiming cage net as a kind of byproduct.Because Rapana venosa is that bottom is dwelt life, caught using diver
When it is high, dangerous big to drag for cost, and being caught with cage net, because the different design of cage net closes the behavior ecology study of Rapana venosa
Property, causes to fish extremely inefficient, can not meet the market demand.
The content of the invention
It is an object of the invention to provide a kind of device and its method for entrapping for traping Rapana venosa, it is red to solve sea area middle arteries
Spiral shell fishes that efficiency is low, fishes the problem of cost is high.
The purpose of the present invention is achieved through the following technical solutions：
The trap of the present invention includes ball float, nylon rope and multigroup spheroid group, wherein each spheroid group includes branch
Frame and multiple spheroids being connected on the support, between each spheroid and support in each group of spheroid group, adjacent
Respectively by described between support between the support in spheroid group and in the ball float and the superiors' spheroid group
Nylon rope is connected；Each spheroid is hollow structure, and multiple holes are provided with surface, the surface of each spheroid
And the internal Rapana venosa bait for being placed with trapping Rapana venosa.
Wherein：The opening of each spheroid is equipped with inwardly open inverted beard shape purse seine；The inverted beard shape purse seine
Opening radius is the 50%~70% of the spheroid opening diameter；
Each spheroid group is from top to bottom in turn connected into pyramidal structure, the spheroid in adjacent ball nullisomic group it
Between mutually abut；The bulb diameter of the spheroid is 30cm~50cm, the 70%~90% of a height of bulb diameter of segment, spheroid
Thickness is 3mm~5mm；The distance between a diameter of 3cm~7cm in the hole, the edge of the edge far from adjacent holes in each hole
For 3cm~5cm；The material of the spheroid is opaque heavy water-based plastic material；The support is sphere of movements for the elephants shape.
The method for entrapping of trap of the present invention is：
The surface of each spheroid and it is internal place Rapana venosa bait, will be in every group of spheroid group it is each described
Spheroid is connected on the support in this group by the nylon rope respectively, and the support in adjacent ball nullisomic group passes through
Nylon rope connection, the ball float are connected with the support in the superiors spheroid groups by the nylon rope；Inside is contained
Each spheroid group of Rapana venosa bait launches the sea area into Rapana venosa natural distributed, and Rapana venosa trap fishing, and returns
When receiving the trap, take out and be attached to each spheroid surface and internal Rapana venosa and add the Rapana venosa again
After bait, the trap is launched into the sea area into Rapana venosa natural distributed again, continues to trap Rapana venosa.
Wherein：Reclaimed after 3~5 days in the sea area that the trap launches Rapana venosa natural distributed.
Advantages of the present invention is with good effect：
1. the agent structure unit of trap of the present invention is spheroid, the hole on spheroid surface can be such that Rapana venosa smoothly leads to
Cross, take full advantage of attachment space of the spheroid surfaces externally and internally as Rapana venosa, can smoothly lure that Rapana venosa enters trap into
Inner space, increase fish efficiency.
2. trap of the present invention, in dispensing and recovery, the hole on spheroid surface can smoothly make current by mitigating
Weight of the trap in operation, operation is light, laborsaving, while can also strengthen the wind and wave resistance characteristic of trap.
3. the opening of the spheroid of trap of the present invention is provided with inverted beard shape purse seine, the arteries and veins inside spheroid is limited
Red spiral shell is escaped from by spheroid opening.
4. trap of the present invention is trapped with the low value shellfish such as mussel, oyster and clam and fishes Rapana venosa, cost is low, efficiency
Height, effect are good.
5. the material of trap of the present invention is plastic material, seawater corrosion resistance is reusable, cost-effective, loss
It is low.
6. method for entrapping of the present invention is simple, easy to operate.
