Abstract
The open a kind of fisheries biology of this utility model and large jellyfish classification catching net, including major network capsule (1), it is characterized in that: the port of export at major network capsule (1) has been simultaneously connected with fisheries biology net capsule (2) and Jellyfish net capsule (3), afterbody Jellyfish net capsule (3) connects float (4), it it is Jellyfish net capsule entrance (5) between Jellyfish net capsule (3) and major network capsule (1), and between fisheries biology net capsule (2) and major network capsule (1), it is fisheries biology entrance (6), and described Jellyfish net capsule entrance (5) is positioned between the entrance of major network capsule (1) and fisheries biology entrance (6), and screening mesh sheet (7) it is additionally provided with at described fisheries biology entrance (6) place.This is that one can carry out classification fish for large jellyfish (sand is bitten) and fish, shrimp, Eriocheir sinensis, siphonopods etc., improves the catching net of catches classification effectiveness.
Description
Technical field
This utility model relates to a kind of catching net, particularly a kind of fisheries biology and large jellyfish classification catching net.
Background technology
At present, using Trawl gear to carry out fishery resources survey is a kind of relatively conventional investigation method.But in recent years by
The phenomenon that change in ecological environment causes Jellyfish to break out happens occasionally, if being by chance to meet Jellyfish outburst in trawlnet investigation,
Then the catches such as fish, shrimp, Eriocheir sinensis are often mixed in together with Jellyfish.Owing to the build of part species of jellyfish (as sand is bitten) is relatively big,
And health is easily broken, so when carrying out catches sorting, owing to mixing of large jellyfish causes the kinds such as fish, shrimp, Eriocheir sinensis
Sorting difficulty, catches sorting work wastes time and energy, inefficiency.It would therefore be highly desirable to research and development one can be at trawlnet fact-finding process
In large jellyfish and other catches are effectively separated, it is possible to achieve classification sorting netting gear.
Summary of the invention
This utility model is to solve the above-mentioned deficiency existing for prior art, and proposing one can be to large jellyfish
(sand is bitten) and fish, shrimp, Eriocheir sinensis, siphonopods etc. carry out classification and fish for, and improve the catching net of catches classification effectiveness.
Technical solution of the present utility model is: a kind of fisheries biology and large jellyfish classification catching net, including main
Net capsule 1, it is characterised in that: the port of export at major network capsule 1 has been simultaneously connected with fisheries biology net capsule 2 and Jellyfish net capsule 3, at Jellyfish net
The afterbody of capsule 3 connects float 4, be Jellyfish net capsule entrance 5 between Jellyfish net capsule 3 and major network capsule 1, and fisheries biology net capsule 2 and
It is fisheries biology entrance 6 between major network capsule 1, and described Jellyfish net capsule entrance 5 is positioned at the entrance of major network capsule 1 and fisheries biology enters
Between mouth 6, and at described fisheries biology entrance 6, it is additionally provided with screening mesh sheet 7.
This utility model compared with the existing technology, has the advantage that
The advantages such as the catching net of this kind of version, has simple in construction, designs ingenious, rationally distributed.It utilizes water
Female this macrozooplankton has this feature of motion habit from the bottom to top, and creatively the rear portion at major network capsule is connected to
Two net capsules are positioned at the fisheries biology net capsule of lower section and Jellyfish net capsule above, and wherein Jellyfish net capsule is come by float
Ensureing to be in all the time upper position, the porch at fisheries biology net capsule is provided with a screening mesh sheet, this screening the most again
The fisheries biology that mesh sheet can allow build relatively small enters in fisheries biology net capsule smoothly, and the relatively large Jellyfish of build is then
It is merely able to upwards move about and eventually enter in Jellyfish net capsule.This makes it possible to accomplish Jellyfish and fisheries biology while fishing for
It is automatically separated, eliminates utilization tradition netting gear and fish for descendant's work point from Jellyfish and the step of fisheries biology, reduce labor intensity,
Improve work efficiency.And the processing technology of this catching net is simple, cheap for manufacturing cost, it can be said that he possesses
Multiple advantage, is particularly suitable for popularization and application in the art, and its market prospect is the most wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.As shown in Figure 1: a kind of fisheries biology is with big
Type Jellyfish classification catching net, including major network capsule 1, the port of export at major network capsule 1 has been simultaneously connected with fisheries biology net capsule 2 and Jellyfish
Net capsule 3, wherein the afterbody of Jellyfish net capsule 3 connects float 4, and this float 4 ensure that the afterbody of Jellyfish net capsule 3 is always positioned at
The top of fisheries biology net capsule 2, above-mentioned Jellyfish net capsule 3 is Jellyfish net capsule entrance 5 with the intersection of major network capsule 1, and fisheries biology
Net capsule 2 is fisheries biology entrance 6 with the intersection of major network capsule 1, and Jellyfish net capsule entrance 5 is positioned at entrance and the fishery of major network capsule 1
Between biological entrance 6, at fisheries biology entrance 6, it is additionally provided with screening mesh sheet 7, the width of mesh of this screening mesh sheet 7 simultaneously
Can allow and need the fisheries biology fished for enter in fisheries biology net capsule 2 smoothly, build then can be sieved by relatively large Jellyfish
Network selection sheet 7 stops.
The fisheries biology of this utility model embodiment is as follows with the work process of large jellyfish classification catching net: by this dress
The major network capsule 1 put is connected to trawler rear portion by hawser, when trawler is advanced, and the major network capsule 1 of this device, fisheries biology
Net capsule 2 and Jellyfish net capsule 3 all open, and under the effect of float 4, the afterbody of Jellyfish net capsule 3 remains at fisheries biology net
The top of capsule 2；In the process that this netting gear is advanced, the fisheries biology that large jellyfish and needs fish can entering by major network capsule 1
Mouth enters major network capsule, and these catches arrived at fisheries biology entrance 6 through Jellyfish net capsule entrance 5 later, owing to arranging in this place
The mesh of screening mesh sheet 7 fish, shrimp, Eriocheir sinensis, siphonopods etc. can be allowed to enter in fisheries biology net capsule 2, and build is relatively large
The most screened mesh sheet of Jellyfish 7 stops, because Jellyfish has the characteristic that float type is travelling, therefore Jellyfish can upwards move about and finally enter
Enter in Jellyfish net capsule 3, thus achieve the purpose automatically separated with fisheries biology by Jellyfish during fishing for.
