Problem to be solved: to provide a cylindrical feeding basket of shellfish with a support frame to prevent deformation of the support frame because the round cage is strongly pressed against the ship slip at the time of winding. The cylindrical aquaculture cage of the shellfish which has enhanced the support frame has a circular support frame 1, three reinforcing beams 2 joined to pass through the center of the support frame 1, a dish net 3 formed with the support frame 1 and the reinforcing beam 2 covered with a web net, and the plate net 3 at a predetermined interval up and down A side net 4 formed by placing the outer side of the dish net 3 in a net net and having a knot in the coupling part 5 of the support frame 1 and the reinforcing beam 2, passing through the mesh of the side network 4 and forming a knot in the lower stage dish network 3, respectively, and hanging rope 6 or the like to be connected to each other It is possible to greatly reduce the deformation of the support frame 1 by the external force, and by setting the suspension rope 6 to three, the plane is determined and stabilized, and the resistance due to the tidal current is reduced. Diagram【課題】巻き上げ時船べりに丸篭が強く押し当てられるため支持枠が変形することを防止する支持枠を増強した貝類の円筒状養殖篭を提供する。【解決手段】支持枠を増強した貝類の円筒状養殖篭は、円形の支持枠1と、支持枠1の中心を通るように接合された3本の補強梁2と、支持枠1と補強梁2を網地で被って形成した皿網3と、皿網3を上下に所定間隔を空けて配置し、皿網3の外側を網地で筒状に被って形成した側網4と、支持枠1と補強梁2との結合部5に結び目を形成して側網4の網目を通過して下段の皿網3にそれぞれ同様に結び目を形成して連結した吊ロープ6とから構成され、支持枠1が外力により変形することを大幅に軽減できるし、吊ロープ6を3本にすることで平面が決定され安定するし、潮流による抵抗が減少する。【選択図】図1
