From April through June 1991, we tested a full‐scale deterrent system for excluding alewives Alosa pseudoharengus from the intake of the James A. FitzPatrick Nuclear Power Plant (JAF), near Oswego, New York. This electronic system produced high‐frequency broadband sound (122–128 kHz) at a source level (in decibels [dB] in reference to 1 μPa) of 190 dB. When the system was on, the density of fish near the JAF intake decreased by as much as 96% and the number of alewives impinged on the intake screens at JAF decreased by as much as 87%. The system was effective during both day and night, and its range was greater than 80 m.
