Description

  The present invention relates to an aquaculture cage used for aquaculture of bivalves such as scallops and pearl oysters, and relates to an aquaculture cage having a plurality of pocket portions serving as aquaculture rooms.

  In general, in the cultivation of shellfish such as scallops (hereinafter referred to as “shellfish”), a continuous cultivation cage in which a plurality of cultivation chambers are formed in a pocket shape by netting in the final stage of cultivation is used.

  As a prior art example having such a configuration, for example, a flat cage disclosed in Japanese Patent Laid-Open No. 48-80392 is representative. In this conventional car, the opening of the pocket is closed to prevent the shell from escaping, and a synthetic resin mouth stitching thread is passed in the lateral direction of the opening while passing through the mesh of the back and front meshes. It is tied to the side string.

  Passing this seam thread through the entire continuous cage requires a lot of labor and labor, and even when the shell is taken out of the pocket part, it is forced to remove the seam thread individually, Therefore, it was inefficient for fishermen.

  In addition, as suggested in the public utility Showa 48-79794, there are some which fix the pocket part to the cross rail with a hook, but as with the preceding example, the fixing work is forced for each pocket. Although the efficiency of the system is somewhat improved, it is not freed from laborious work.

  Under such circumstances, the present inventor has proposed, as Japanese Patent Application Laid-Open No. 2011-55754, a continuous culture cage in which pocket presser lids that seal the openings of the pockets of the continuous culture cage are attached to the horizontal rails so as to be freely opened and closed.

  However, the continuous culture cage is suspended in a cage and installed in the sea, but in the culture cage in the sea, the pocket presser lid is lifted by the vertical movement of the cage due to tides and waves, and the pocket opening is sealed. There was a risk that the shells in the pockets would escape into the sea. Therefore, it is possible to prevent the pocket presser lid from lifting up by tying the pocket frame of the pocket presser lid and the next horizontal rail with a string, but the pocket presser lid formed in multiple stages is tied to the horizontal rail. The work is time-consuming, and when removing the shellfish, the work of unraveling the individually tied strings is added, and the inefficiency is not improved.

Japanese Patent Laid-Open No. 48-80392 Public utility Showa 48-79794 specification JP 2011-55754 A

  The present invention solves such a problem, and a pocket presser lid that seals a plurality of pocket openings can be closed by a simple means even in the vertical movement of a cage caused by the influence of tides and waves. It is an object of the present invention to provide a continuous culture cage with a pocket presser lid that can prevent escape of shellfish and can open a pocket opening by simple means.

  In order to achieve the above-mentioned object, the present invention seals the opening of a culture cage in which pockets serving as an aquaculture chamber are formed in a plurality of stages in the vertical direction by overlapping nets and binding the three sides except the upper opening. It is a two-stage aquaculture cage with a pocket presser lid attached to a side rail so that it can be freely opened and closed, with two closing ropes that sequentially bind both lower corners of the lid frame body constituting the pocket presser lid vertically. The upper lid frame is connected to a plurality of lid frames at the same time, and a plurality of groups of the connected bodies are formed to form the lowermost lid frame and the next stage. It is fixed by hanging a locking tool on the side rail.

  Further, the sealing rope of the present invention is a single piece in which a plurality of pocket presser lids are collectively connected by vertically binding one of the lower corners of the lid frame of the pocket presser lid in the vertical direction. It may be a rope.

  Further, the locking device of the present invention is a hook member that hooks and fixes the lid frame body at the lowermost end of the combined body of pocket presser lids and the horizontal rail at the next stage.

  According to the present invention, the lid frame of the pocket presser lid that holds down the opening of the pocket is sequentially tied in the vertical direction by one or two continuous closing ropes, and a plurality of steps are formed from the upper pocket presser lid. A set of connected bodies is stretched in a lump over the eye pocket presser lid, and a plurality of sets of the connected bodies are formed over the entire length of the continuous culture cage. Each pocket presser lid is connected and fixed by locking the bottom side of the lid frame body at the lowermost end of the pocket presser lid and the horizontal rail of the next stage with a locking tool. That is, when a multi-stage aquaculture cage constructed in this way is installed in the sea, the pocket presser lid can be prevented from floating even if it encounters the vertical movement of the cage due to tides or waves, and the shellfish can enter the sea from the opening of the pocket. Can prevent you from running away.

  Also, suspend the upside-down farming baskets upside down, and remove the locking tool spanned between the bottom frame of the pocket presser lid and the horizontal rail of the next stage. The pocket presser lids connected together by the closing rope are opened all at once, the opening is released, and the shells in the pocket can be discharged at once, so that the work efficiency is greatly improved.

One sealing rope 16 is used to sequentially form the left and right lower corners 12b of the lid frame 12 of the pocket presser cover 11 in the vertical direction. It is the composition which is bound to. That is, one lower corner portion 12b of the U-shaped lid frame body 12 constituting the pocket presser lid 11 is bound, and then one lower corner portion 12b of the lid frame body 12 of the pocket presser lid 11 at the next stage is bound. After that, one lower corner portion 12b of the lid frame body 12 is sequentially bound in the vertical direction, and finally, the lower corner portion 12b of the lid frame body 12 of the seventh to eighth step pocket presser lid 11 is bound. As shown in FIG. 1, a plurality of sets of connected bodies 18 are provided in the same manner as in the embodiment shown in FIG. 1. In addition, it is the same as that of the said Example to provide the 1 or 2 locking tool 17. FIG.

  Next, the operation of the present invention will be described. The opening portion 7a of the pocket 10 of the continuous culture cage 1 is opened, and the required number of shellfish A to be cultured is introduced. The shells are sequentially accommodated in the pockets 10 of each step, and the shells are arranged and accommodated so as not to overlap each other. At this time, the pocket presser lid 11 for pressing the opening 7a of the pocket 10 is rotated about the horizontal rail 3 as a support shaft to expose the opening 7a. The operation of housing the shell A in the pocket 10 is performed at a beach workplace or on board.

  Next, after the shell A is accommodated in the pocket 10, the opening 7 a is sealed by rotating the pocket pressing lid 11 and overlapping the pocket 10. Thereafter, a sealing rope 16 is tied to the lower corner portion 12b of the U-shaped lid frame 12 of the upper pocket presser lid 11, and the lower corner portion 12b of the lid frame body 12 of the next pocket presser lid 11 is connected in the following order. A plurality of tiers are tied together to form a set of connected bodies 18. Two sealing ropes 16 are prepared and tied one by one to the lower left and right corners 12b of the U-shaped lid frame 12 one by one, and the 7 to 8 pocket presser lids 11 from the upper stage are bundled together. It is. Lastly, the connecting body 18 of the pocket presser lid 11 which is a batch is fixed by hooking a locking tool 17 such as a hook on the bottom frame 12c of the lowermost lid frame 12 and the horizontal rail 3 at the next stage.
