The present invention facilitates the insertion of the locking pin to the engaging hole provided in the spats ear piece, facilitated, facilitation of mounting operation of the locking pin in the scallop farming work, facilitation, so as to obtain improve efficiency and scallops the entire A to provide a locking pin for aquaculture is resin-forming, a runner section 3 of the rod, the runner portion 3 from branches at a right angle, and a small diameter of the gate portion 4 than the diameter of the runner part, this consisting of finished product 2 Metropolitan provided ahead of the gate portion 4. The finished product portion 2, peripheral tip portion insertion portion 5a of the ear hanging holes were drilled in the scallops ears on opposite ends of the shaft portion 21, and 6a, the inner portion each axis of the tip portion the insertion portions 5 and 6 of the shaft portion It has a pair of scallops engaging portions 7 and 8 which projects in the direction of the rope retaining engagement portion 9, 10 which protrudes in the longitudinal direction intermediate portion of the shaft portion in the circumferential direction. The runner 3 is one article, the gate portion 4, by cutting the boundary portion between the formed article 2, the locking member aquaculture scallop is obtained. .BACKGROUND【課題】稚貝耳片に設ける掛止孔への係止ピンの挿入を円滑、容易化し、帆立貝養殖作業における係止ピンの装着作業の円滑、容易化、効率化を図り得るようにした帆立貝養殖用の係止ピンを提供する【解決手段】全体が樹脂形成され、棒状のランナ部3と、このランナ部3から直角に分岐し、ランナ部の径よりも小径のゲート部4と、このゲート部4の先に設けられる成品部2とからなる。成品部2が、軸部21の両端部に帆立貝耳片に穿孔した耳吊り孔への先部挿入部5a,6aと、軸部の先部挿入部5,6の各軸内方部に周方向に突出する一対の帆立貝係止部7,8と、軸部の長さ方向中間部に周方向に突出するロープ抜止係止部9,10を有する。ランナ部3は一条であり、ゲート部4を、成品部2との境界部で切断することで、養殖帆立貝の係止具が得られる。【選択図】図3
