PROBLEM TO BE SOLVED: To provide a shellfish hanger that enables resources saving and labor saving in the structure and formation, and furthermore, eliminates deformation, breakage and strain in transportation, storage and aquaculture on-site handling, is stable and easy even in attachment, and reduces a load by perforation of spats and greatly decreases detachment, and also facilitates recovery.SOLUTION: A parallel-shaped connecting scallop hanger is characterized as follows: a shell insert tip 2 is formed at both ends in the longitudinal direction of a base 1 of a shellfish hanger； at least a pair of shellfish acquisition units comprising a barb structure of a curved fork-end having a pair of upward and downward different curvature radiuses is installed in a position inside from the distal end； a pair of rope stopper projections 41' in the state where a projecting tip is inclined to the center side is installed in a central portion of the longitudinal direction of the base； and further, it can be connected with the bases of a shellfish hanger piece-part being present in an interval of the pair of rope stopper protrusions 41' and provided with at least one tie line member 5 extending in the right angle direction substantially from the position of the central part of the base, and other shellfish hangers.SELECTED DRAWING: Figure 1【課題】構造および成形において省資源、省力化ができて、しかも、輸送、保管、養殖現場の取り扱いにおいて、変形、破損、歪みが無く、取付けも安定、容易で、かつ稚貝の穿孔による負荷を軽減して、脱離が非常に少なく、回収も容易な貝掛止具を提供する。【解決手段】貝掛止具の根幹１の長手方向の両端に貝殻挿入用先端部２が形成されており、その先端部より内側の位置に一対の、上向き、下向きの異なる曲率半径を有する湾曲形状の二又のアグ（かえし）の構造からなる少なくとも一対の貝捕捉部が設置されており、根幹の長手方向の中央部分には突起状の先端部が中心側に傾斜した状態の一対のロープ止め用突起４１´が設置され、さらに対のロープ止め突起４１´の間隔内にあり、根幹のほぼ中心部の位置から直角方向に伸びる少なくとも一本の連結線部材５が設けられている貝掛止具単品、及び他の貝掛止具の根幹と連結可能した並列状連結帆立貝掛止具である。【選択図】図１
