Abstract

The utility model relates to an alarming type floating net which is composed of a net body 1, a float line 2, a sinker line 3, floats 4 and sinkers 5. The utility model is characterized in that the upper part of the float line 2 is connected with a hanging system 7 and a hanging float 6; the lower part of the sinker line 3 is connected with an alarming and collecting line 8. Therefore, the fishery resource is protected, and the fishing yield is increased. The utility model is especially suitable for fishing portunids on sea bottom.

Description

Agitation formula drift net

The utility model is a kind of instrument of fishing for, particularly a kind of drift net that is suitable for swimming crab.

In the past, China fished for swimming crab mainly by trawlnet, and the trawlnet mesh is few, and it is serious to destroy aquatic resources, and country has forbidden to use trawlnet; Can only fish for a spot of set gill net now.But, utilize set gill net to fish for and to catch by fine swimming crab, thereby output is very low the seabed because swimming crab lives under the silt.

The purpose of this utility model will provide a kind of exactly can not destroy aquatic resources, makes the high-yield agitation formula of swimming crab flow perverse net again.

The purpose of this utility model is achieved in that a kind of drift net, form by etting 1, headline 2, ground rope 3, float 4, sinker 5, it is characterized in that it is 7 that described each headline 2 at least 6 of connection are hung, hanging is that 7 other ends connect that to make etting 1 be in hanging of plumbness in the sea floating 6, connects 12 agitation guiding principles 8 for 3 times at ground rope.

It is 12 that optimum implementation of the utility model alarms guiding principle 8 the bests exactly, and agitation guiding principle 8 adopts diameter 16mm coir rope, every long 40cm, and hanging coefficient amount the best is 6, its length is the height that the depth of water deducts net height and agitation guiding principle.

The utility model compared with prior art has the following advantages:

1. owing to adopt agitation guiding principle 8, the swimming crab in the silt of seabed can have been alarmed water, be wrapped in simultaneously on the etting 1, reach and fish for purpose, thereby improved fishery output.

2. bigger owing to etting 1 mesh, thereby aquatic resources are protected.

Accompanying drawing and drawing explanation:

1. etting 2. headlines 3. ground ropes 4. floats 5. sinkers 6. hang floating 7. to hang are 8. agitation 13. seas, guiding principle 9. bush ropes, 10. fishing boat 11. bush rope dropstones, 12. seabeds, 14. awns Ziqis

Embodiment:

1. etting 1 wide 2000.5 orders, high 24.5 orders, the big 120mm of order, hanging ratio are 0.33, and with diameter 0.18 collodion silk line, two fast knots braidings form, and headline 2 adopts 57 strands of polyethylene ropes, and is bifilar, is connected 80 meters of length with a limit of etting 1; Same ground rope 3 also adopts 57 strands of polyethylene ropes bifilar, is connected with another long limit of etting 1, and length also is 80 meters.Connect a float 4 every 96cm on the headline 2, float 4 usefulness plastic foamboards are slit into cuboid, every 4 * 2 * 2cm connects a sinker 5 every 96cm on ground rope 3, sinker 5 is used plummet, become streamlined, heavy 21g, every 16m, it is 7 that connection one is hung at headline 2, hanging is 72 strands of polyethylene ropes of 7 usefulness, is 6.Hang is 7 length=and the depth of water-net height-agitation guiding principle is long, hangs floating 7 upper ends and connects and hang floatingly 6, hangs floating 6 usefulness diameter 7cm duroplasts floats, connects agitation guiding principle 8 in ground rope 3 lower ends, and agitation guiding principle 8 is 12, the coir rope of employing diameter 16mm, every long 40cm.

During use, earlier every net is linked together with 72 strands of polyethylene ropes, it connects 20, connects together at band net well rope 9 and plummet 11 and fishing boat 10 then, then net is put in the sea, hang to float 6 and float on the sea 13, and be 7 to make etting 1 vertical below by hanging; Simultaneously, under the effect of sinker 5, etting 1 vertical erecting in seabed portion.Alarm guiding principle 8 and be attached on the seabed 12 this moment, starts fishing boat 10, and agitation guiding principle 8 is pasting seabed 12 and alarming, and at this moment, the swimming crab in the silt that sinks to the bottom of the sea is twined by etting 1 with regard to round-up on the net, just reaches and fishes for purpose.

Claims

1, a kind of agitation formula drift net, form by etting 1, headline 2, ground rope 3, float 4, sinker 5, it is characterized in that it is 7 that described headline 2 at least 6 of connections are hung, hanging is that 7 other ends connect that to make etting 1 be in hanging of plumbness in the sea floating 6, connects at least 1.2 guiding principles 8 of alarming 3 times at ground rope.

2,, it is characterized in that described guiding principle 8 the bests of alarming are 12 according to the described agitation formula of claim drift net.

3. agitation formula drift net according to claim 1 and 2 is characterized in that described agitation guiding principle 8 adopts diameter 16mm coir rope, every long 40cm.

4. agitation formula drift net according to claim 3 is characterized in that described hanging is that 7 the bests are 6, and its length=depth of water-net height-agitation guiding principle is long
