PROBLEM TO BE SOLVED: To provide an electrode apparatus for generating an electric field and/or a magnetic field for guiding aquatic lives.SOLUTION: An electrode apparatus 70 includes a plurality of electrode devices 174 for generating an electric field and/or a magnetic field for guiding aquatic lives. The plurality of electrode devices 174 are disposed in water separately from one another, and when an electric pulse is applied to at least one electrode device 174 of the plurality of electrode devices 174, an electric field and/or a magnetic field are generated around the at least one electrode device 174. A first section and a second section are formed by the electric field and/or the magnetic field, the first section and the second section being sections separately closed. Stimulation is given to the aquatic lives by the electric field and/or the magnetic field for guiding the aquatic lives so as to selectively move the aquatic lives from the first section to the second section, and from the second section to the first section.SELECTED DRAWING: Figure 10【課題】水中生物を誘導するための電界及び／又は磁界を発生させるための電極装置を提供する。【解決手段】水中生物を誘導するための電界及び／又は磁界を発生させるための複数の電極手段１７４を備える電極装置７０であって、前記複数の電極手段１７４は水中に互いに離間させて配置され、前記複数の電極手段１７４のうちの少なくとも１つの電極手段１７４に電気パルスが印加されることにより、前記少なくとも１つ電極手段１７４の周囲に電界及び／又は磁界を生じさせ、前記電界及び／又は磁界によって、第１の区画及び第２の区画を形成し、前記第１の区画及び前記第２の区画は別個に閉じられた区画であり、前記第１の区画から前記第２の区画へ及び前記第２の区画から前記第１の区画へ、前記水中生物を選択的に移動させるように、前記電界及び／又は磁界によって水中生物に刺激を与えて水中生物を誘導する。【選択図】図１０
