Abstract
The utility model discloses a kind of reverse frustoconic net cage, it is characterized in that, net cage is up big and down small reverse frustoconic, is made up of Shang Quan, water wing, upper cover net piece, foundation ring, centre circle, strengthening support, upside side wall mesh sheet, downside side wall mesh sheet, bottom mesh sheet, sinker, pulling rope, moorstone；Use the utility model reverse frustoconic net cage, in the large-scale space in silver carp bighead life net cage upper strata, it is easy to water body inside and outside net cage to exchange, abundant planktonic organism is obtained, a small amount of middle lower floor fish raised together with, which are concentrated, to be moved in the less net cage space of ground floor area, and supplement feed concentrates on smaller range, lower floor fish ingests in convenient, the silver carp bighead on upper strata is had a role to play with middle lower floor fish, and net cage space is fully used, and culture efficiency is good.
Description
Technical field
The utility model is related to fish production field, specifically a kind of reverse frustoconic net cage.
Background technology
Cage culture is a kind of important productive of fish culture, and also fish are cage culture to the filter-feeding such as silver carp bighead
Important kind, silver carp bighead is general using planktonic organism as Major Foods, and planktonic organism mainly moves in the upper strata of water body, is abundant
Using net cage space, lower floor fish, such as crucian, Pelteobagrus fulvidraco, carp, megalobrama amblycephala typically in silver carp bighead net cage raises together with some,
Tradition cultivation silver carp bighead typically uses cuboid net cage, and this net cage is unfavorable for the exchange inside and outside planktonic organism net cage, is unfavorable for
Epipelagic fish silver carp bighead ingests, and middle lower floor fish also because space is excessive, that supplement feed sheds scope is excessive, be not easy to fill
Divide and utilize supplement feed, and then floating influences ingesting and perching for upper strata silver carp bighead.
The content of the invention
To overcome drawbacks described above, the utility model devises a kind of reverse frustoconic net cage.
The technical solution of the utility model is, a kind of reverse frustoconic net cage, it is characterized in that, net cage is up big and down small rounding
Platform shape, is upper circle on the top periphery of net cage, water wing is tied up on upper circle periphery, is easy to set on the inside of the floating of net cage, upper circle and covers
Mesh sheet, sets fish inlet, fish inlet is usually tied up with rope, in the bottom periphery of net cage in upper cover net piece close to the side of upper circle
Foundation ring is set, and foundation ring diameter is less than upper loop diameter, centre circle is set in upper circle and the middle of foundation ring, middle loop diameter is more than foundation ring diameter
Less than upper loop diameter, some strengthening supports are set between upper circle and foundation ring, the centre of strengthening support is tied up on centre circle, in upper circle and
Upside side wall mesh sheet is set between centre circle, and side wall mesh sheet on the downside of setting, sets bottom on the inside of foundation ring between centre circle and foundation ring
Mesh sheet, some sinkers are set on foundation ring periphery, keep net cage in the balance on water body upper strata, drawing is set in the side of upper circle
Rope, the other end of pulling rope is tied up on moorstone.
Beneficial effect：Using the utility model reverse frustoconic net cage, in the large-scale space in silver carp bighead life net cage upper strata,
It is easy to water body inside and outside net cage to exchange, obtains abundant planktonic organism, a small amount of middle lower floor fish raised together with, which are concentrated, moves in bottom
In the less net cage space of area, supplement feed concentrates on smaller range, it is convenient in lower floor fish ingest, the silver carp bighead on upper strata
Had a role to play with middle lower floor fish, net cage space is fully used, culture efficiency is good.
Brief description of the drawings
Fig. 1 is the utility model structure chart.
In figure：1 water wing, is enclosed on 2,3 upside side wall mesh sheet, cover net piece on 4,5 centre circles, 6 strengthening supports, 7 fish inlets, 8 drawings
Rope, 9 downside side wall mesh sheet, 10 bottom mesh sheet, 11 foundation rings, 12 moorstones, 13 sinkers.
Embodiment
It is described with reference to the drawings the utility model, a kind of reverse frustoconic net cage, it is characterized in that, net cage is up big and down small rounding
Platform shape, is upper circle 2 on the top periphery of net cage, and water wing 1 is tied up on 2 peripheries of upper circle, is easy to the floating of net cage, and the upper inner side of circle 2 is set
Upper cover net piece 4, sets fish inlet 7 close to the side of upper circle 2 in upper cover net piece 4, is tied up when fish inlet 7 is flat with rope, in net cage
Bottom periphery set foundation ring 11, the diameter of foundation ring 11 be less than it is upper circle 2 diameters, it is upper circle 2 and foundation ring 11 in the middle of set centre circle 5,
The diameter of centre circle 5 is more than the diameter of foundation ring 11 and is less than 2 diameters of upper circle, sets some strengthening supports 6 between upper circle 2 and foundation ring 11, reinforces
The centre of support 6 is tied up on centre circle 5, set between upper circle 2 and centre circle 5 on the upside of side wall mesh sheet 3, centre circle 5 and foundation ring 11 it
Between downside side wall mesh sheet 9 is set, bottom mesh sheet 10 is set in the inner side of foundation ring 11, some sinkers 13 are set on the periphery of foundation ring 11,
Keep net cage in the balance on water body upper strata, pulling rope 8 is set in the side of upper circle 2, the other end of pulling rope 8 is tied up in moorstone 12
On.
Beneficial effect：Using the utility model reverse frustoconic net cage, in the large-scale space in silver carp bighead life net cage upper strata,
It is easy to water body inside and outside net cage to exchange, obtains abundant planktonic organism, a small amount of middle lower floor fish raised together with, which are concentrated, moves in bottom
In the less net cage space of area, supplement feed concentrates on smaller range, it is convenient in lower floor fish ingest, the silver carp bighead on upper strata
Had a role to play with middle lower floor fish, net cage space is fully used, culture efficiency is good.
