摘要： PROBLEM TO BE SOLVED: To provide an aquatic life elimination device and a method of eliminating an aquatic life which can eliminate the aquatic life relatively easily at low cost with low power consumption, and as a result can eliminate a nest of the aquatic life. SOLUTION: The elimination device 20 is provided with a plurality of electrode bars 21, 21, etc., a power source 23 and a voltage control part 24. Each of the electrode bars 21 is provided at intervals on the inner wall surface of a head race channel 4 which is in a position closer to a water intake 3 than the nearly midpoint of the head race channel 4 in the longitudinal direction. Then the voltage control part 24 controls the length of the time period of the non-application of a voltage, the length of the time period of the application of the voltage, and placement between the time period of the non-application of the voltage and the time period of the application of the voltage. During the time period of the non-application of the voltage, the aquatic life suspended in the water in the head race channel 4 is adhered to the inner wall surface of the head race channel 4 and nested without the application of the voltage to the electrode bars 21, 21, etc. On the other hand, during the time period of the application of the voltage, the aquatic life, which is adhered to the inner wall surface of the head race channel 4 during the period of the non-application of the voltage is moved away from the inner wall surface by the application of the voltage to the electrode bars 21, 21, etc. COPYRIGHT: (C)2007,JPO&INPIT
