Conventionally, latches for scallop culture are known (for example, see Patent Document 1 and Patent Document 2).
Japanese Patent No. 3375617 Japanese Patent Application Laid-Open No. 10-113090.

FIG.11 and FIG.12 is a repost figure of the latching tool of FIG. However, the code was re-assigned.
The hook 101 has a sharp tip at the tip 102a of the shaft 102, and includes a first hook 103 that extends in a shape immediately after the axial direction, and a second hook with a large diameter at the rear end of the shaft. 104, each part is integrally molded with resin.
An attachment hole 106 is provided in the rope 105, and the ear pieces 107 a and 107 a of the scallops (scallop larvae) 107 and 107 arranged above and below the rope while passing the shaft portion 102 of the latch 101 through the attachment hole 106. The hook is passed through the hole, and the scallops 107 and 107 are hooked with the rope 105 sandwiched between the hook 101 (see FIG. 11A). The upper and lower scallops 107 and 107 in the figure have a larger diameter than the mounting holes of the ear pieces 107 a and 107 a, and the scallops 107 and 107 come out of the hook 101. Without being held (see FIG. 11B).

FIG. 12 shows the scallop farming state. A large number of latches are passed through and locked on the rope 105 at a predetermined pitch so as to be orthogonal to the axial direction, and scallops 107 are attached to both ends of each latch 101. 107 are hung and aquaculture is performed.
FIGS. 13 and 14 are explanatory diagrams showing the disadvantages of the latching device according to Patent Document 1. The ropes 105 and 105 are hung by a hanging metal fitting 109 on a bus bar 108 that extends horizontally in the sea, and are understood in the drawings. As shown, a plurality of scallops 107 (...) are provided at both ends of the ropes 105, 105 through the hooks 101 at a predetermined pitch in the length direction (longitudinal direction, gravity direction). The same shall apply hereinafter).

The scallops 107, 107 that are hooked at both ends of the hook 101 are merely penetrated and held in the attachment holes 106 of the rope 105, so that the sea current, the growth condition, the movement of the scallops, etc. The shaft portion of the hook 101 moves within the rope attachment hole 106.
As a result, it moves to one side as shown in FIGS. 13 and 14, the scallop on one side of the rope is close to the rope, and the other side is away from the rope, and the prey condition of the scallop sandwiches the rope 105 In other words, the growth of the scallops is not substantially equal, and the cultured scallops have large variations, making it difficult to obtain uniform scallops.
