Description
Technical field
The utility model belongs to fishing for of aquaculture and adopts the field of catching, specifically a kind of device of traping Rapana venosa.
Background technology
Rapana venosa Rapana venosa, is commonly called as " spinach spiral shell ", " conch ", belongs to Mollusca, Gastropoda, Muricidae, and red spiral shell belongs to, and adult shell Gao Keda 11 ~ 12cm, China Bohai Sea and the Huanghai Sea all have distribution.Rapana venosa foot is loose especially, and delicious flavour is nutritious, very people institute eating, and economic worth is high.In the last few years, along with the decline of Rapana venosa near-coastal resources and the situation of selling well of domestic and international market, its economic worth improved constantly, and current live body price is 20 ~ 40 yuans/kilogram.
At present, Rapana venosa has the very large market demand in China Bohai Sea and Huanghai Sea bank, because artificial breeding technique is not broken through, realizes industrialized scale far away, causes propagating artificially and cannot carry out on a large scale.Therefore, Rapana venosa becomes spiral shell to be mainly derived from sea area to adopt and catch, but adopt the efficiency of catching compared with low, cost large, can not meet the demand in market far away.Cause Rapana venosa to become spiral shell to adopt catching inefficient reason be Rapana venosa adopt the mode of catching.Up to now, the mode of catching of adopting of Rapana venosa mainly relies on diver to carry out manpower to adopt and catch, or obtains as a kind of by product when reclaiming cage net.Because Rapana venosa is life of dwelling at the end, use diver to fish for cost high, dangerous large, and when fishing for cage net, the different design due to cage net closes the behavioral ecology habit of Rapana venosa, cause adopting the efficiency of catching extremely low, cannot meet the need of market.
Utility model content
The purpose of this utility model is to provide a kind of device of traping Rapana venosa, solve Rapana venosa in sea area adopt catch efficiency low, adopt and catch the high problem of cost.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises ball float, nylon rope and many group spheroid groups, wherein each spheroid group includes support and multiple spheroid be connected on this support, and each described spheroid in each group spheroid group is connected respectively by described nylon rope with between the described support between support, in adjoining segment body group and between described ball float with the support in the superiors spheroid groups; Each described spheroid is hollow structure, has multiple hole on the surface, and the surface of each described spheroid and inside are all placed with the Rapana venosa bait of trapping Rapana venosa.
Wherein: the opening part of each described spheroid is equipped with the inverted beard shape purse seine to inner opening; Described inverted beard shape purse seine opening part radius is 50% ~ 70% of described spheroid opening part diameter;
Each described spheroid group is in turn connected into pyramidal structure from top to bottom, abuts mutually between the described spheroid in adjoining segment body group; The bulb diameter of described spheroid is 30cm ~ 50cm, and segment height is 70% ~ 90% of bulb diameter, and spheroid is thick is 3mm ~ 5mm; The diameter in described hole is 3cm ~ 7cm, the edge in each described hole far from adjacent holes edge between distance be 3cm ~ 5cm; Described support is sphere of movements for the elephants shape.
Advantage of the present utility model and good effect are:
1. agent structure unit of the present utility model is spheroid, the hole on spheroid surface can make Rapana venosa pass through smoothly, take full advantage of the attachment space of spheroid surfaces externally and internally as Rapana venosa, can lure that Rapana venosa enters the inner space of trapping device smoothly into, increase to adopt and catch efficiency.
2. the utility model is when throwing in and reclaim, and the hole on spheroid surface can make current pass through smoothly, alleviating the weight of trapping device when operating, operating light, laborsaving, also can strengthen the wind wave resistance characteristic of trapping device simultaneously.
3. the opening part of spheroid of the present utility model is provided with inverted beard shape purse seine, and the Rapana venosa limiting spheroid inside is escaped from by spheroid opening part.
4. the utility model lures centralized procurement to catch Rapana venosa with low value shellfishes such as mussel, oyster and clams, and cost is low, and efficiency is high, effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model one group of spheroid group;
Fig. 3 is the structural representation of the utility model spheroid;
Wherein: 1 is inverted beard shape purse seine, and 2 is hole, and 3 is spheroid, and 4 is support, and 5 is ball float, and 6 is nylon rope.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As described in Figure 1, the utility model comprises ball float 5, nylon rope 6 and many group spheroid groups, wherein each spheroid group includes support 4 and multiple spheroid 3 be connected on this support 4, and each spheroid 3 in each group spheroid group is connected respectively by nylon rope 6 with between the support 4 between support 4, in adjoining segment body group and between ball float 5 with the support 4 in the superiors spheroid groups.Each spheroid group is in turn connected into pyramidal structure from top to bottom, abuts mutually between the spheroid 3 in adjoining segment body group.
Shape, the size of each spheroid 3 in each group of spheroid group are all identical, as shown in Figure 3, each spheroid 3 is hollow structure, all be placed with the Rapana venosa bait of trapping Rapana venosa on the surface of each spheroid 3 and inside, the Rapana venosa bait of the present embodiment can be the low value shellfishes such as mussel, oyster and clam.The bulb diameter of spheroid 3 is 30cm ~ 50cm, segment height is 70% ~ 90% of bulb diameter, spheroid is thick is 3mm ~ 5mm, the material of spheroid 3 is opaque heavy water-based plastic material, as PVC (polyvinyl chloride) or PP (polypropylene), seawater corrosion resistance, reusable, cost-saving, loss is low.The surface of each spheroid 3 all has multiple hole 2, and the diameter in hole 2 is 3cm ~ 7cm, the edge in each hole 2 far from adjacent holes edge between distance be 3cm ~ 5cm.
Be equipped with the inverted beard shape purse seine 1 to inner opening at the opening part of each spheroid 3, this inverted beard shape purse seine 1 opening part radius is 50% ~ 70% of spheroid 3 opening part diameter.
