Abstract

The invention relates to a harpadon nehereus catching cage device for large water surfaces. The cage device comprises a cage device framework, wherein the cage device framework is formed through welding steel-bar upright columns, an upper interlayer bottom and a lower interlayer bottom are arranged inside the cage device framework and are formed through connecting netting sheets, vertical type steel-bar inverted whiskers are mounted at the middle parts of the upper and lower interlayer bottoms so as to form an interlayer fish storehouse, outer side faces of the cage device framework are wrapped with netting sheets so as to form a cage body, the cage body is vertical and square, four fish inlets are respectively formed in the middle part and lower part of the cage body, four steel-bar inverted whiskers are mounted at the four fish inlets and are fixed by the netting sheets, a cage hanging nose and a fish taking door are respectively arranged at one corner and one side of the top of the cage body, one end of the fish taking door is fixed by movable hinges, the other end of the fish taking door is connected with a door hook, the fish taking door can be vertically opened/closed under the action of the door hook, and fish bait bags are respectively arranged at the bottom of the cage body and on the lower interlayer bottom and are connected and fixed by fish bait bag pull ropes.

Description

The large water surface catches leading Fish trap

Technical field

The present invention relates to one and catch leading Fish trap, particularly a kind of large water surface catches leading Fish trap, belongs to fishpot tool technical field.

Background technology

At present, people are when the large-scale aquiculture water surface fishes for leading fish, main employing be trawlnet, trawlnet is put into water, start lift supporting rod netting gear is strutted, start towboat netting gear is dilatory various fishes fishing disembarkation fast, although fishing output is many, but because ship's speed is fast, fish class in trawlnet risk one's life struggle, cause various fish badly wounded in struggle, after fish catch out the water surface, lethality is high, Bombay duck belongs to benthic fishes in addition, a large amount of Bombay ducks cannot be captured with trawlnet, therefore drag a net in fishing with ship and not only cannot reach the object of the fresh and alive listing of various fish, reduce its due commodity value, a large amount of leading fish can't be caught.

Summary of the invention

The object of the invention is to: provide that a kind of structure is simple, storage area be large, be convenient to transport, be easy to operate, catch Bombay duck amount high, little to fish damage, fish class and the large water surface of one of fresh and alive listing can catch leading Fish trap, overcome the above-mentioned defect that existing trawlnet peculiar to vessel is existing when fishing on large water surface.

The technical solution adopted for the present invention to solve the technical problems is: a kind of large water surface is caught leading Fish trap and comprised cage tool framework, cage tool framework has reinforcing steel bar upright post to be welded, cage tool lower portion is provided with at the bottom of interlayer with at the bottom of lower interlayer, mesh sheet is had to be formed by connecting at the bottom of upper interlayer Yu at the bottom of lower interlayer, vertical steel bar inverted beard is installed with medium position at the bottom of lower interlayer at the bottom of upper interlayer form interlayer and store up fish storehouse, the lateral surface of cage tool framework is enclosed with mesh sheet and forms cage body, cage body is vertical type square, the middle part of cage body and bottom arrange four fish inlets respectively, four fish inlets are provided with four steel bar inverted beards, four steel bar inverted beards have mesh sheet to fix, one jiao, cage body top and side are respectively arranged with cage nose and the door of falling fish, the one end of falling Yu Men has movable hinge to fix, one end is connected with a hook in addition, upper and lower switch can be realized under the effect of the Men Men of falling fish hook, attracting bag is respectively arranged with above the bottom of cage body and lower interlayer, attracting bag has attracting bag stay cord to be connected and fixed.

Beneficial effect of the present invention: owing to present invention employs such scheme, the large water surface is caught after leading Fish trap enters water, namely the leading bait that lures be placed in cage tool can send dense raw meat fragrance, and be diffused into far waters rapidly, after Bombay duck smells raw meat fragrance, namely the hunger of Bombay duck is increased, capital is found aroma source and is sought food, enter in cage tool and rob food bait, because four fish inlets are all provided with steel bar inverted beard, and steel bar inverted beard is pre-large post-small, the Bombay duck entered in cage tool be namely captured, cannot escape from, reach object of the present invention, the large water surface of the present invention catches leading Fish trap, and to have structure simple, storage area is large, be convenient to transport, be easy to operation, catch Bombay duck amount high, little to fish damage, fish class can the advantage of fresh and alive listing, the institute's Bombay duck lethality of catching effectively overcoming existing ship trawlnet existing when fishing on large water surface is high, catch the defect of Bombay duck weak effect.

Below in conjunction with accompanying drawing, the invention will be further described.

Accompanying drawing explanation

Fig. 1 is structure chart of the present invention.

Embodiment

As shown in Figure 1, the large water surface of the present invention is caught leading Fish trap and is comprised cage tool framework 1, cage tool framework 1 has reinforcing steel bar upright post 3 to be welded, cage tool framework 1 inside to be provided with at the bottom of interlayer 9 with at the bottom of lower interlayer 10, at the bottom of upper interlayer, 9 10 have mesh sheet 4 to be formed by connecting with at the bottom of lower interlayer, at the bottom of upper interlayer 9 with at the bottom of lower interlayer 10 medium position vertical steel bar inverted beard 11 is installed forms interlayer and store up fish storehouse 12, the lateral surface of cage tool framework 1 is enclosed with mesh sheet 4 and forms cage body, cage body is vertical type square, the middle part of cage body and bottom arrange four fish inlets 5 respectively, four fish inlets 5 are provided with four steel bar inverted beards 6, four steel bar inverted beards 6 have mesh sheet 4 to fix, one jiao, cage body top and side are respectively arranged with cage nose 2 and the door of falling fish 13, the door of falling fish 13 one end has movable hinge 14 to fix, one end is connected with a hook 15 in addition, the door of falling fish 13 can realize upper and lower switch under the effect of door hook 15, the bottom of cage body and lower interlayer 10 are respectively arranged with attracting bag 7 above, attracting bag 7 has attracting bag stay cord 8 to be connected and fixed.

The above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that the common engineers and technicians in this area make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
