PROBLEM TO BE SOLVED: To provide a stationary net that eliminates entering of large jellyfish such as Stomolophus nomurai by a simple improvement, effectively catches fishes and is effective even in change in the direction of flow of ocean current.SOLUTION: The fenced net of a stationary net arranged in a fishing ground of ocean current flow has a constitution that the fenced net includes an opening through which a large jellyfish passes, an entrance net that introduces a large jellyfish moving in an edge port direction at the upstream side of the opening and an exit guide net that introduces a large jellyfish in the downstream direction of the opening, the entrance guide net and the exit guide net are complementary and fishes moving in the edge port direction along the fenced net are passed through the opening and do not directly see a view at the opposite side of the fenced net.COPYRIGHT: (C)2009,JPO&INPIT【課題】 簡単な改良によってエチゼンクラゲ等の巨大クラゲの入網を排除し、魚を有効に捕獲すると共に海流の流れ方向が変化しても有効な定置網を提供すること。【構成】 海流が流れている漁場に設置される定置網の垣網において、前記垣網に巨大クラゲが通過する開口を設けると共に、該開口の上流側で端口方向に移動する巨大クラゲを該開口に誘導する入口ガイド網と該開口の下流方向に誘導する出口ガイド網を設け、該入口ガイド網と該出口ガイド網は相補って、該垣網に沿って端口方向に移動する魚に該開口を通して直接に該垣網の反対側の景色が見えないように構成したことを特徴とする。【選択図】 図1
