< Topic >At the time of tight selvage cultivating of one sequence expression of the scallop, through the person in charge stopping pin to the rope containment, the person in charge stopping pin which can assure the improvement of the yield which the person in charge it is possible, in scallop cultivating to raise the parity of the scallop which makes stop is offered.SolutionsIs interposed to the tight selvage hole which in both destals of frame 2 is punched in the lug piece of the scallop it possesses ahead interposition section 3,3, it possesses the scallop person in charge lock part 4,4 of the pair which to each axial inner split section of tip interposition section 3,3 of frame 2 projects to circumferential direction, lap it possesses the rope locking person in charge lock part 5,5 which projects to direction in the intermediate section of length direction of the frame, all it forms the person in charge stopping pin 1 for the scallop cultivation which resin formed as one unit. As for length of tip interposition section 3 of person in charge stopping pin 1, length L1 to the base of scallop person in charge lock part 4, made 0.03 time - 0.08 times from the Tip 2a vis-a-vis frame total length L, in addition, the tight selvage hole Perforating on only one side of the scallop lug piece facilities to be done, through this stopping hole with the person in charge stopping pin, in the person in charge stopping pin which is used for one sequence cultivation which tight selvage is done.< Choice figure >Drawing 1【課題】帆立貝の一枚通し式の耳吊り養殖において、ロープに係止ピンを介して保持、係止させた帆立貝の反転性を高めることができ、帆立貝養殖における収穫量の向上を図ることができる係止ピンを提供する。【解決手段】軸部2の両端部に帆立貝の耳片に穿孔した耳吊り孔へ挿入する先部挿入部3,3を有し、軸部2の先部挿入部3,3の各軸内方部に円周方向に突出する一対の帆立貝係止部4,4を有し、軸部の長さ方向の中間部に周方向に突出するロープ抜止係止部5,5を有し、全一体に樹脂成形された帆立貝養殖用の係止ピン1を形成する。また、耳吊り孔は、帆立貝耳片の一枚側にのみ穿設され、係止ピンでこの掛止孔を介して耳吊りする一枚通し養殖に用いる係止ピンにおいて、係止ピン1の先部挿入部3の長さは、その先端部2aから帆立貝係止部4の基部までの長さL1が、軸部全長Lに対し、0.03倍~0.08倍とした。【選択図】図1
