Abstract
A kind of list ship krill trawlnet structure, there is wing list capsule trawlnet using small mesh list ship, it is characterized in that trawlnet body net sutures for six chip of four-piece type structure, it is PE mesh grids to carry on the back net and upside net, belly and downside net are PA mesh grids, the upper and lower sides net stitching section mesh that grades is isometric, is saved in net capsule front three and installs PA of the mesh no more than 30mm in body net additional and serve as a contrast net without knot, and passes through etting outside the oblique net muscle connection lining net of "×" font and body net；It is bifilar PE mesh grids that net capsule, which uses straight barrel type structure, length 45m, the outer etting of net capsule, and net capsule liner net is mesh 15mm PA knotless nets, and diameter 24mm ultra-high strength polyethylenes rope is installed additional as explosion-proof muscle at interval of 1.5m.It can be used for improving krill trawlnet fishing performance.
Description
Technical field
The present invention relates to krill trawlnets.
Background technology
Krill stock number is abundant, and the fishery developed country headed by Norway, Japan, South Korea etc. is continuously increased in the South Pole
Input on krill resources development and utilization, fishing and processing technology are also at rank first.At present to krill
Fishing mainly has two kinds of single ship otter trawl and pump suction type side of a ship trawlnet.But single ship otter trawl be divided into for network interface mesh 10m with
Upper, net gap perimeter is more than two kinds of the small mesh trawlnet of the trawl with big meshes and network interface mesh of 800m at tens centimetres, but major network body is equal
Using polyethylene or nylon homogenous material.
China formally started to have raised the new page of China's deep-sea fishing into the fishing South Pole in 2009/2010 year fishing season.China
It is large-scale trawlnet factory ship to catch krill fishing boat, and used netting gear is mainly from external import.With regard to current use situation
From the point of view of, other than netting gear cost is higher, external netting gear fails to consider the present situation of China's fishing boat well, and it is poor to fit fishing.
Netting gear again according to actually being trimmed and being adjusted, increases the secondary input of cost in use for some time.
For krill cluster on daytime with respect to comparatively dense, night is more dispersed, therefore it is required that trawlnet has higher vertical expansion
And horizontal expansion, to improve the drainage volume of netting gear to increase fishery harvesting effect.There is presently no one kind suiting China's fishing boat
Krill trawlnet that is practical and carrying certain self-expanding energy, the highly desirable blank for making up this field.
Invention content
The purpose of the present invention is to propose to one kind being suitble to 3000-5500Kw large size trawler list ship krill trawlnet structures,
To improve China's krill trawlnet fishing performance.
Technical scheme of the present invention has wing list capsule trawlnet using small mesh list ship, it is characterized in that trawlnet body net is four-piece type knot
Six chip of structure sutures, and it is PE mesh grids to carry on the back net and upside net, and belly and downside net are PA mesh grids, and upper and lower sides net stitching section grades
Mesh is isometric, and save PA of the installation mesh no more than 30mm in body net in net capsule front three serves as a contrast net without knot, and oblique by "×" font
Net muscle connection lining net and the outer etting of body net；Net capsule uses straight barrel type structure, and length 45m, the outer etting of net capsule is bifilar PE mesh grids,
Net capsule liner net is mesh 15mm PA knotless nets, and diameter 24mm ultra-high strength polyethylenes rope is installed additional as explosion-proof muscle at interval of 1.5m.
List ship krill trawlnet structure of the present invention has fishing gear resistance compared with the large mesh krill trawlnet that China had previously used
Power is small, acts the feature for putting that net is convenient and the time is short, to improve the vertical self-expanding of netting gear, while improving netting gear intensity and wear-resisting
Performance, the outer etting of body net using high-strength polyethylene (PE), the litzendraht wire etting of two kinds of different specific weights of nylon (PA), carry on the back net and on
Side net uses PE litzendraht wire ettings, and belly and downside net use PA litzendraht wire ettings, and the upper and lower sides net stitching section mesh that grades is isometric, i.e.,
Netting gear main body is four-piece type structure makes trawlnet low towing speed shape under water by PE and two kinds of different densities web pre fetching structures of PA
Under state, also can vertical opening open；To prevent krill from escaping, while netting gear totality water filtering performance is improved, is saved in net capsule front three outer
It installs PA of the mesh no more than 30mm in net additional and serves as a contrast net without knot, and pass through the oblique net muscle connection lining net of "×" font and outer etting；Net
It is bifilar PE litzendraht wires that capsule, which uses straight barrel type structure, length 45m, outer etting, and interior etting is mesh 15mmPA knotless nets, at interval of
1.5m installs diameter 24mm ultra-high strength polyethylenes rope additional as explosion-proof muscle, improves krill trawlnet fishing performance.

Specific implementation mode
Illustrate specific implementation mode below in conjunction with the accompanying drawings：
Embodiment 1：Trawlnet body net sutures for six chip of four-piece type structure, and it is high-strength polyethylene (PE) to carry on the back net and upside net
Mesh grid, belly and downside net are PA mesh grids, and the upper and lower sides net stitching section mesh that grades is isometric, save in body net in net capsule front three plus
It fills PA of the mesh no more than 30mm and serves as a contrast net without knot, and pass through etting outside the oblique net muscle connection lining net of "×" font and body net；Net capsule
Using straight barrel type structure, length 45m, the outer etting of net capsule is bifilar PE mesh grids, and net capsule liner net is mesh 15mm PA without knot
