PROBLEM TO BE SOLVED: To provide a method for instantaneously killing jellyfish polyp with electric shock after recovering the net adhered with polyps in the bottom of a barge at sea level in order to prevent the power reduction caused by jellyfish in power plants as means for solving the power shortage which is a drag on the Japanese economic recovery without further delay.SOLUTION: The jellyfish is instantaneously killed by giving an electric field generated with direct-current through the electrode pair while jellyfish polyp collection nets spread in the sea from the bottom of a barge at sea level and collected are passing through a tank.COPYRIGHT: (C)2014,JPO&INPIT【課題】日本経済複興の足かせとなつている電力不足を一日も早く解決する手段として発電所のクラゲによる発電量低下をなくすため、海面の台船の底部のポリプ付着網を回収し、電気ショックで瞬間的にクラゲポリプを死滅させる方法を提供する。【解決手段】海面の台船の底部からクラゲポリプ採取網を海中に展開して回収してタンクを通過させる間に直流で発生した電場を電極対により与えることで瞬間的に死滅させる。【選択図】図8
