Abstract

A scoop net for fishing live jellyfishes relates to the marine organism fishing technology. In the technical scheme of the invention, the scoop net comprises a net ring, a mesh bag and a handle, and is characterized in that: two half rings are adopted as a front half net ring and a rear half net ring of the net ring, both ends of the front half net ring are articulated with both ends of the rear half net ring, so that the round net ring is formed, limit plates are arranged on the ends of the rear half net ring, so that the two half net rings can be formed into the planar round net ring after being unfolded by 180 degrees, a rope-fastening ring is arranged at the middle of the outer side of the front half net ring, the handle is connected with the middle of the outer side of the rear half net ring, and hanging rods or hanging hooks are respectively arranged on the inner sides of the front half net ring and the rear half net ring; a circle of fine canvas which is 3cm to 5cm wide is sewed on the opening of the mesh bag, small holes are evenly distributed on the fine canvas sewed on the opening, small iron rings are embedded in the small holes, and a connecting rope are threaded through the small iron rings to connect the mesh bag and the net ring together; the bottom of the mesh bag is made of a fine canvas, and the mesh bag bottom made of the fine canvas is 35cm to 70cm deep.

Description

A kind of diddle-net of fishing for the live body jellyfish

Technical field

The present invention relates to marine organisms and fish for technology, especially fish for the netting gear of live body jellyfish.

Background technology

The season that large jellyfish breaks out, the ecological severe exacerbation in marine site, the intensive part of jellyfish, the explosion of fishery netting gear, mesh stop up very general, and normal fish production activity is had a strong impact on, and catch reduces, fishes for that cost improves, fisherman's burden.Solve this fishery disaster; At first need find out the history of life of large jellyfish, just need catch a large amount of live body jellyfishes and do laboratory research, yet the main component of jellyfish health be a water; And form by inside and outside two germinal layers; Two interlayers have a very thick mesoglea, and are not only transparent, and floating effect is arranged.In view of this characteristic of jellyfish, if directly go to fish for jellyfish, very easily damage the jellyfish individuality, and jellyfish is individual in case suffer to damage and just can't survive, can't do indoor laboratory research with general netting gear.Therefore, need a kind of netting gear of fishing for the live body jellyfish that is specifically designed to, for the laboratory provides technical support to the ecological Studies of jellyfish.

Summary of the invention

The problem that the present invention need solve is to create a kind of diddle-net of fishing for the live body jellyfish that is specifically designed to.

Technical scheme of the present invention is made up of net circle, mesh bag and handle; It is characterized in that adopting two semicircle circle bodies to net circle and later half net circle as preceding half of net circle respectively; Circular net circle of the hinged formation in two ends of preceding half net circle and later half net circle; Limiting plate is established in the end of later half net circle, becomes planar rondure net circle when two and half net circle expansion 180 are spent, and the outer middle side part of preceding half net circle has the rope clasp; The outer middle side part connection hand handle of later half net circle, preceding half net circle and later half net circle inboard are respectively equipped with hanger bar or hanged hook; It is the fine canvas of 3-5cm that the network interface of mesh bag is sewed up a circle width, and even distribution aperture is bumped into little iron ring on the fine canvas that network interface is sewed up on the aperture, passes little iron ring hole with connection cord mesh bag and net circle are connect; The bottom of mesh bag adopts fine canvas to make, the dark 35-70cm in mesh bag bottom that fine canvas is made.

Outstanding feature of the present invention is and can stays live body jellyfish individuality and seawater in the mesh bag bottom simultaneously; Avoid the damage of live body jellyfish; Improved the survival rate of live body jellyfish greatly; Unnecessary seawater can be discharged through the etting at mesh bag middle part, and the folding back of net circle as a lid are lived the diddle-net flap, prevents that the jellyfish that catches from escaping.

Description of drawings

What accompanying drawing was represented is net coil structures sketch map of the present invention.

Embodiment

The present invention's (referring to accompanying drawing) is made up of net circle 1, mesh bag and handle 2; Adopt two semicircle circle bodies to net circle and later half net circle as preceding half of net circle respectively; Circular net circle of the hinged formation in two ends of preceding partly net circle and later half net circle, the end downside of later half net circle is established limiting plate 3, and two and half nets are enclosed becomes planar rondure net circle when expansion 180 is spent; The outer middle side part of preceding half net circle has rope clasp 5; The outer middle side part connection hand handle of later half net circle, half net circle was scratched swivel pin with later half net circle is superimposed before the rope clasp of half net circle can make before the pull-up, and preceding half net circle and later half net circle inboard are respectively equipped with hanger bar 4 or hanged hook and mesh bag connection; It is the fine canvas of 3-5cm that the network interface of mesh bag is sewed up a circle width, and even distribution aperture is bumped into little iron ring on the fine canvas that network interface is sewed up on the aperture, can pass little iron ring hole with connection cord mesh bag and net circle are connect; The bottom of mesh bag adopts fine canvas to make, the dark 35-70cm in mesh bag bottom that fine canvas is made.

Claims

1. diddle-net of fishing for the live body jellyfish; Form by net circle, mesh bag and handle; It is characterized in that adopting two semicircle circle bodies to net circle and later half net circle as preceding half of net circle respectively, circular net circle of the hinged formation in two ends of preceding half net circle and later half net circle, limiting plate is established in the end of later half net circle; When being spent, two and half net circle expansion 180 become planar rondure net circle; The outer middle side part of preceding half net circle has the rope clasp, the outer middle side part connection hand handle of later half net circle, and preceding circle and the later half net circle inboard of partly netting is respectively equipped with hanger bar or hanged hook; It is the fine canvas of 3-5cm that the network interface of mesh bag is sewed up a circle width, and even distribution aperture is bumped into little iron ring on the fine canvas that network interface is sewed up on the aperture, passes little iron ring hole with connection cord mesh bag and net circle are connect; The bottom of mesh bag adopts fine canvas to make, the dark 35-70cm in mesh bag bottom that fine canvas is made.
