Most of the work has been done with members of the herring family in order to keep fish out of water intakes at various power facilities. There was some effort to use sound to move salmon and steelhead smolts away from turbine intakes but that was unsuccessful. I've never heard of the work done on carp before this.
A guy I work with has done some work with American shad and sound avoidance lately. He's trying to scare shad away from gear that is supposed to be sampling salmon smolts. I thinnk he's using 40 to 60 Hz sound. Apparently, it has shown some promise.
