SCALLOP CULTIVATION FASTENING PIN AND SCALLOP HARVEST METHOD

PROBLEM TO BE SOLVED: To provide a scallop fastening pin and a scallop harvest method, capable of separating and removing a fastening pin from a rope at the same time as squeeze separation of a scallop from the rope in the harvest of the scallop.SOLUTION: The cultivation method of scallop includes the steps of: suspending and holding scallops at fastening parts at tips of a fastening pin 1 penetrated through a through hole 21 arranged in a rope 20 perpendicularly to the length direction of the rope 21; and suspending the rope in the sea. The fastening pin 1 includes a fragile part 7 located between rope stop pieces 6, 6 and broken by a particular force. The scallop harvest method includes the steps of: pulling up the rope suspending grown-up scallops from the sea by a winch or the like; passing the rope between squeezing members, which include a narrow part a little larger than thickness of the rope; passing the rope in the narrow part between the squeezing members; hanging the scallops on the squeezing members; allowing the fragile part 7 to break to squeeze off the scallops from the rope 20; and removing out broken fastening pins 1A, 1B from the rope 20. 【課題】帆立貝の収穫時における帆立貝のロープからの扱き離脱時に、同時に係止ピンをロープから離脱除去可能とする帆立貝の係止ピン及び帆立貝の収穫方法を提供する。【解決手段】ロープ２０に長さ方向に直交するように設けた貫通孔２１に通した係止ピン１の先端部の係止部に帆立貝を吊り下げ保持し、海中にロープを垂らして行う帆立貝の養殖方法において、係止ピン１のロープ抜止片６，６間には一定の力で破断する脆弱部７を有し、生育後の帆立貝を吊り下げているロープを海中から巻揚機等で引き上げ、ロープを扱き部材間に通し、扱き部材間には、ロープの太さよりも若干大きい狭隘部を有し、扱き部材間の狭隘部間にロープを通し、帆立貝を扱き部材に引っ掛け、脆弱部７を破断させることでロープ２０から帆立貝を扱き落とすとともに、破断した係止ピン１Ａ，１Ｂをロープ２０から抜き出すようにした帆立貝の収穫方法。【選択図】図１２
