Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Fig. 1 to 10, the fishing fishing net that this contains minute fish gathering unit, comprises fishing fishing net device 1, divides the stretching device 6 of fish gathering unit 2 and hollow, and this fishing fishing net device 1 is connected by zipper 4 with a minute fish gathering unit 2.Divide fish gathering unit 2 to comprise at least two minutes fish devices 3, between this minute fish device 3, be provided with minute fish dividing plate 5 and interconnect by slide fastener 4.The forward and backward opening of this stretching device 6 is connected with a minute fish device 3 by slide fastener 4.The elliptical shape that fishing fishing net device 1 in the present embodiment is opening, minute fish device 3 and stretching device 6 are cylindrical shape.The mesh of peripheral mesh and minute fish dividing plate 5 adopts rectangle mesh simultaneously, one side every all the overlapping of mesh has rotating plastic pipe.
During the design of mesh size, the external network Kongzui of fishing fishing net device 1, stretching device 6 and minute fish gathering unit 2 is little, and the mesh size of minute fish dividing plate 5 reduces step by step along the direction away from this fishing fishing net device 1.
The enforcement principle of the fishing fishing net that this is contained to minute fish gathering unit below and minute fish dividing plate 5 sizes, number are selected to briefly explain.
The netting gear of fishing fishing net, its major parameter structure is network interface mesh number, netting gear length, height of net opening, network interface width etc.In recent years, generally hull bottom traw mouth mesh number is designed to 800-900 order, and netting gear total length is 55-65m, and according to the depth of water with drag guiding principle length height of net opening and generally change at 4.3-6.1m, width generally changes at 14.5-15.9m.The towing speed of operation is controlled at 3.0-3.5kn, and the trawlnet time is 1-2 hour.In trawlnet process, fish relies on momentum effect and the rotating plastic pipe of water, slides to rear section fish gathering unit 2.After fishing for, utilize a minute fish gathering unit 2 to carry out automatic separated and collected.Each fraction fish gathering unit 2 and the long 0.8m of stretching device 6, bottom surface diameter is 2m.
Marine species is owing to being subject to the impact of the factors such as temperature, weather, environment, and it can show region, ocean, each some seasonal group differences.In the face of different sea area and seasons, our starting point is by mainly for the more sociales of those numbers.Take the East Sea as example, and the fingerling of East China Sea region is that fish are maximum, and shell-fish takes second place, and siphonopods is minimum, and also presenting Perciformes, Pleuronectiformes and crab class is main bodily form classification.From the whole year, fish amount kind from more to less in region, the East Sea is followed successively by hairtail, scad, Anchovy, luminous porgy, yellowfin black scraper Puffer, little yellow croaker, swordtip squid, Pacific Ocean pleat squid, silvery pomfret, Ovalipes punctatus, pampano, scomberomorus niphonius, Bombay duck, green fin black scraper Puffer, chub mackerel, slice India fish, the two squids in Hawaii, yellow porgy and other kinds.East Sea dominant species in each, average body is long, average body is wide as shown in table 1 in season.
Table 1: East Sea dominant species in each, average body is long, average body is wide in season
By the bodily form to sociales, analyze, we have divided the mesh size of 7 kinds of minutes fish dividing plates 5 substantially, be respectively 65mm*65mm, 55mm*55mm, 45mm*45mm, 40mm*40mm, 30mm*30mm, 20mm*20mm, 10mm*10mm, can better carry out according to actual needs size fractionation like this.Generally, we take 3 other gathering units of level, and within its minute, fish dividing plate 5 sizes are respectively 55mm*55mm, 30mm*30mm, 10mm*10mm.As the East Sea for spring, fish amount kind is from more to less Anchovy, luminous porgy, hairtail, scomberomorus niphonius, little Huang, Ovalipes punctatus, swordtip squid, scad, silvery pomfret, Pacific Ocean pleat squid successively.Its sociales and wide Anchovy 12mm-18mm, luminous porgy 68mm-72mm, hairtail 50mm-70mm, scomberomorus niphonius 47mm-143mm, little yellow croaker 37mm-48mm, Ovalipes punctatus 30mm-43mm, swordtip squid 15mm-30mm, scad 50mm-60mm, silvery pomfret 66mm-100mm, the Pacific Ocean pleat squid 50mm-65mm of being followed successively by of average body corresponding to this time.Can take the mesh baffle dimensions of 55mm*55mm, 30mm*30mm, tri-classifications of 10mm*10mm as the large, medium and small classification foundation of oneself.When this fish of Anchovy is through the first fraction fish dividing plate 5(55mm*55mm), because the wide 12mm-18mm of its body is less than this size, can automatically enter the second fraction fish dividing plate 5(30mm*30mm), wide this size that is less than again of its body, enter the third level and divide fish dividing plate 5(10mm*10mm), its body is wider than this size and stays in the 3rd region.According to this principle, every fish enters minute fish gathering unit 2(Fig. 1-2) after, all, according to and minute fish dividing plate 5 sizes wide from health, enter in suitable region.Most of Anchovy is mainly in the 3rd region, most of luminous porgy is mainly at second area, most of hairtail is mainly at second area, part scomberomorus niphonius is at second area, most of scomberomorus niphonius is mainly in first area, part little yellow croaker is in the 3rd region, most of little yellow croaker is mainly at second area, most of Ovalipes punctatus is mainly in the 3rd region, most of swordtip squid is mainly in the 3rd region, most of scad is mainly at second area, part silvery pomfret is at second area, most of silvery pomfret is mainly in first area, most of Pacific Ocean pleat squid is mainly at second area, with regard to having completed, make corresponding fish be collected in first like this, second, the effect in the 3rd region.Because Anchovy quantity is maximum, consider that the 7th fraction fish device 3 length in the 3rd region are inadequate, can before the 3rd region of collecting Anchovy, connect stretching device 6, increase length.
From seasonal, in certain degree, really exist the difference of dominant population in addition, but can, according to the actual needs with reference to above-mentioned form, reasonably take corresponding minute fish dividing plate 5 sizes and corresponding dividing plate number.Each fingerling because the effect meeting of current along with the drive of current enters in net, and when by minute fish dividing plate 5 from big to small of mesh, according to belonging to self other stratum reticulare of level from wide automatically the entering into of health.And for the zones of different of each ocean, fingerling difference also can exist, if but the main fish in this region and above-mentioned fish bodily form range differences are few, can be mesh size (55mm*55mm, 30mm*30mm, the 10mm*10mm) application of minute fish dividing plate generally using in the past, if difference is very large, according to fingerling, selects suitable minute fraction fish dividing plate 5 sizes or suitably minute fraction fish dividing plate 5 sizes carried out to some and revise, using again afterwards.
