PROBLEM TO BE SOLVED: To provide a continuous shellfish locking tool and a roll-shaped shellfish locking tool that are easy to be wound up into a roll, are easy to be inserted in a vertical rope, are hard to come out of the vertical rope during aquaculture, and are easy to be extracted from the vertical rope after the aquaculture.SOLUTION: A large number of shellfish locking tools with two rope stopper protrusions formed in a truncated chevron shape is arranged in the same direction, the inside of the rope stopper protrusion of each shellfish locking tool is resin-formed integrally with a string-like flexible connecting member, and thereby the large number of shellfish locking tools is connected. The flexible connecting member is shaped in a string with flexibility capable of being wound into a roll, and also shaped in the string with the same size as the rope stopper protrusion or being thicker than that. The above continuous shellfish locking tool is a roll-shaped continuous shellfish locking tool being wound up into a roll by giving a sheet or not giving it, and is a folding continuous shellfish locking tool being folded back and stacked to a desired length by giving the sheet or not giving it.SELECTED DRAWING: Figure 1【課題】 ロール状に巻き易く、縦ロープに差し込み易く、養殖中に縦ロープから抜けにくく、養殖後は縦ロープから抜き取りやすい連続貝係止具とロール状貝係止具を実現する。【解決手段】 二本のロープ止め突起がハ字状に形成された貝係止具が同じ向きで多数本配列され、各貝係止具のロープ止め突起の内側が紐状の可撓性連結材と一体に樹脂成型されて前記多数本の貝係止具が連結されている。可撓性連結材はロール状に巻き取り可能な可撓性を備えた紐状であり、ロープ止め突起と同じであるか又はそれよりも太い紐状である。前記した連続貝係止具が、シートを宛がって又は宛がわずにロール状に巻かれたロール状連続貝係止具、シートを宛がって又は宛がわずに所望長に折り返して重ねた折り重ね連続貝係止具である。【選択図】 図１
