A kind of net cage for sea farming multipurpose etting
Technical field:
The present invention relates to mariculture equipment, particularly purposes etting more than the net cage for sea farming.
Background technology:
The etting of existing net cage for sea farming is made up of top net, spacer screen, side net, net muscle, rete cord cursory and that etting is tied on the net cage frame, and spacer screen has 2 layers of internal layer culturing net and outer protection networks, and the side net has 2 layers of internal layer culturing net and outer protection networks.Existing net cage only is used for single marine product and cultures; As only culture sea cucumber or only culture ocean fish etc., like this then cause the waste of fish culture net cage usage space, in addition because the breakthrough of breeding process biological chain; Then can not make full use of the organic resource of marine creature, not reach best culture benefit.
Summary of the invention:
The object of the invention is to provide a kind of net cage for sea farming multipurpose etting, overcomes the uneconomical of single variety breed, realizes a net is supported more, has both made full use of the net cage facility, makes full use of the biological chain effect again, to reach the best income of culturing.
The present invention is enforcement like this, and a kind of net cage for sea farming multipurpose etting is made up of the holothruian cultures adherance 12 on top net 2, spacer screen 3, the spacer screen, side net 4, net muscle 6, rete cord 7 that etting is tied on the net cage frame.Net 5 in being provided with between said spacer screen and the top net, in be provided with abalone culture on the net and perch base 13, it comprise be distributed in online bird's nest shape perch nest 13 and near the abalone active multi-hole plate 14 of perching nest.
Said bird's nest shape is perched nest and is buckled on the Porous Base 15 by arc buckle closure 16 and constitutes; Its front end has the movable import and export 17 of abalone; The bird's nest shape is perched nest 13 and is distributed ringwise, and abalone is movable imports and exports 17 towards the net center, perches and establishes abalone active multi-hole plate 14 before the activity of nest abalone imports and exports 17.
Said top net 2 is provided with holothruian cultures cleaning door 9 and abalone culture cleaning door 11, connects vertical net tube 10 under the holothruian cultures cleaning door, net holothruian cultures working hole 9 in the termination under the vertical net tube '.
The invention has the advantages that the net cage spacer screen is used to culture sea cucumber, middle net is used for abalone breeding, and the net cage space is fully utilized.Two kinds of marine products are cultured with case, and abalone eats the plankton marine alga, and its excreta then is the food of sea cucumber, constitute food chain, have made full use of the organic resource of marine creature, can practice thrift feed, reduce aquaculture cost, improve culture benefit.

Embodiment:
Below in conjunction with the given embodiment of above-mentioned Figure of description, do an explanation to holding within the present invention.
Accompanying drawing 4 is for having installed the net cage for sea farming front view of the multi-functional etting of the present invention; Accompanying drawing 1 is the local structure sketch map of accompanying drawing 4; Multipurpose net cage etting of the present invention is to be made up of the holothruian cultures adherance 12 on top net 2, spacer screen 3, the spacer screen, side net 4, net muscle 6 and cursory 8, and etting is tied on the net cage frame 1 through rete cord 7.The holothruian cultures adherance is made up of many rows shed shape net nest and a plurality of string bag shape net nests of hanging.Net 5 during the present invention sets up between said spacer screen and top net, in be provided with on the net abalone culture perch basic 13, abalone culture perch base comprise be distributed in online bird's nest shape perch nest 13 and near the abalone active multi-hole plate 14 of perching nest.The bird's nest shape is perched nest and is buckled on the Porous Base 15 by arc buckle closure 16 and constitutes; Its front end is provided with the movable import and export 17 of abalone; The bird's nest shape is perched nest and is distributed ringwise; Abalone is movable imports and exports 17 towards the net center, before the movable import and export of abalone abalone active multi-hole plate 14 is set, like accompanying drawing 2,5,6,7, shown in 8.The bird's nest shape is perched nest 13 and abalone active multi-hole plate 14 and processed by plastic material, and is online in being sewn in.Accompanying drawing 3 pushes up the net vertical view for the present invention, and is visible among the figure, and the top is netted 2 and is provided with holothruian cultures cleaning door 9 and abalone culture cleaning door 11, connects vertical net tube 10 under the holothruian cultures cleaning door, net holothruian cultures working hole 9 in the termination under the net tube '.Can throw seedling, throw feed, nowel work, fish for etc. through top net abalone culture cleaning door 11.Through top net holothruian cultures cleaning door 9, again through vertical net tube 10 and middle net holothruian cultures working hole 9 ' can throw the sea cucumber seedling, throw feed, nowel work, fish for etc.
