Abstract

The utility model relates to a manual fish collecting device orientated to a tuna seine fishery industry. The manual fish collecting device comprises a rectangular frame, a tuna seine is installed in the rectangular frame, multiple floating balls are installed side by side at the top end of the rectangular frame, and steel wires are wound at the bottom end of the rectangular frame. Multiple moso bamboo bars are arranged in parallel at equal intervals in the length direction of the rectangular frame. Curtain-shaped thin bars are wound at the bottom ends of the moso bamboo bars, and coconut tree leaves are evenly distributed on the moso bamboo bars. The manual fish collecting device is simple in structure and composed of the abandoned tuna seine, the utilization rate of a fishing gear is increased, material is easy to obtain, the cost is low, popularization is very easy, meanwhile, industry investment is reduced, and net profits of a fleet of ships are increased.

Description

A kind of artificial fish-aggregating device towards fishery of tuna purse seine
Technical field
The utility model belongs to deep-sea fishing basis production field, particularly relates to a kind of fish gathering efficiency that improves fishery of tuna purse seine, fast fish gathering and the device with efficient fish-gathering effect.
Background technology
Current global fishery of tuna purse seine output has accounted for the over half of tuna gross yield, can create every year higher economic share.And wherein, tuna seine object mainly concentrates on the yellowfin tuna of stripped tuna and little individuality, big-eye tunas etc.Be gathered in offshore floating thing (natural driftwood is if natural landing is to marine trunk because Tuna--like Fishes has, branches etc. and human activity abandon are as plank, oil drum etc.) biological property, fisherman just develops with this artificial fish-aggregating device that is directed to Tuna--like Fishes.Utilize artificial fish-aggregating device operating type quantity of the catch to account for the main share of the total quantity of the catch of purse seine.
But, in actual investigation, different artificial fish-aggregating device fish-gathering effect (fish gathering speed speeds, shoal of fish confining force size and fish gathering amount etc.) but there is very large difference, but ship cannot judge the fish-gathering effect of location artificial fish-aggregating device via satellite when buoy location, the input of ship is fished in the potential increase of meeting like this, comprises fuel cost, fishing gear consumptive material consumption etc.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of artificial fish-aggregating device towards fishery of tuna purse seine, improve artificial fish-aggregating device in fishery of tuna purse seine, improve artificial fish-aggregating effect, play to reduce and fish for the poor probability of ship tracking fish-gathering effect, reduce ship and drop into, the effect of increasing work efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of artificial fish-aggregating device towards fishery of tuna purse seine is provided, comprise rectangular frame, in described rectangular frame, fishing net is housed, the top of described rectangular frame is installed with some ball floats side by side, the bottom of rectangular frame is wound with steel wire, described rectangular frame some mao bamboon bars that have equidistantly been arranged in parallel along its length, described some mao bamboon bars bottom is wound with curtain shape slice, on some mao bamboon bars, is evenly equipped with cocoanut tree leaf.
The length of described curtain shape slice is greater than 1/2 of distance between adjacent mao bamboon bar.
Described curtain shape slice is by discarding fishing net netting twine or discarded woven bag forms through cutting out.
When described curtain shape slice is discarded woven bag material, on woven bag, the adjacent corresponding part of cutting out bar overlaps.
Beneficial effect
Owing to adopting technique scheme, compared with prior art, there is following advantage and good effect:
This device is deep-sea fishing basis production equipment, there is simple structure, adopt discarded fishing net to form, improved the utilization rate of fishing gear, material is easy to obtain on operation ship, with low cost and very easily promote, improvement is mainly intended for and improves the fish-gathering effect of artificial fish-aggregating device, increases filament shape window shade by improvement, increase artificial fish-aggregating device primary productivity around, and then reach the object that increases fish-gathering effect, can accomplish that minimizing industry drops into, and increases fleet's net profit.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this device;
Fig. 2 is the stereogram of this device.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1-2, a kind of artificial fish-aggregating device towards fishery of tuna purse seine, comprise rectangular frame, fishing net 4 is housed in described rectangular frame, the top of described rectangular frame is installed with some ball floats 1 side by side, and the bottom of rectangular frame is wound with steel wire 5, described rectangular frame some mao bamboon bars 2 that have equidistantly been arranged in parallel along its length, described some mao bamboon bars 2 bottoms are wound with curtain shape slice 6, on some mao bamboon bars 2, are evenly equipped with cocoanut tree leaf 3.
The length of described curtain shape slice 6 is greater than 1/2 of distance between adjacent mao bamboon bar 2.
Described curtain shape slice 6 is formed through cutting out by discarded fishing net netting twine or discarded woven bag.
When described curtain shape slice 6 is discarded woven bag material, on woven bag, the adjacent corresponding part of cutting out bar overlaps.
Embodiment 1
Fish-aggregating device (see figure 1) chief component comprises ball float 1: work the floating artificial fish-aggregating device effect of supporting; Mao bamboon 2: got by one whole mao bamboon crosscut, play connection function; Cocoanut tree leaf 3: buy in operation marine site belonging country, the Primary Production nutriment effect that provides is provided; Fishing net 4: form by discarding or damage fishing net, play and form the effect of artificial fish-aggregating device structure minisize ecological system framework; Steel wire 5: formed by merely hit discarded steel wire, steel cable of operation ship, be generally one whole intercepting, play the anti-locking apparatus of weight effect and float on sea.
The utility model (see figure 2) has increased filament on original basis, fine strip shape netting gear 6, distance half between general length of recommended two mao bamboons of length, sheared by fishing lines discarded on operation ship or discarded woven bag equally, suggestion simultaneously, if while adopting fishing lines as this device, preferably increase certain density, make this device comparatively dense, and while adopting discarded woven bag to be cut into fine strip shape, preferably adjacent fine strip shape has certain overlapping, to increase the resistance to ocean current, primary producer is provided better living space, and then play the effect that increases fish gathering efficiency.
