PROBLEM TO BE SOLVED: To solve the problem that a conventional frame for a live-box takes time for removing work of marine periphyton due to its structure for mounting a plurality of floats in a lower side of the frame for a live-box as a frame.SOLUTION: In the frame 4 for a live-box, a partial frame A41, a partial frame B42 and a partial frame C43 having a cross-sectional shape of a substantially circular shape with a plane surface 44 of a predetermined width on an upper surface and having a space divided into a floating part and a buoyancy adjustment part inside thereof are connected in a corridor shape to form an integral frame body, and a net is hung by a hanging tool 14 and an upper frame 15 on an inner side of the frame body.COPYRIGHT: (C)2013,JPO&INPIT【課題】従来の生け簀枠では、フレームとしての生け簀枠の下側に多数のフロートを取り付けるという構造であるため、海洋付着生物の除去作業に時間が掛かるという問題があった。【解決手段】生け簀枠4は、夫々が上面に所定幅の平面44を有した略円形の断面形状で、内部に浮き部と浮力調節部に区画された空間を有する部分枠A41、部分枠B42および部分枠C43とを、回廊状に接続することで一体の枠体にし、前記枠体の内側に吊り下げ具14と上枠15で網を吊り下げている。【選択図】図2
