Abstract

The South American knifefish Eigenmannia sp. can detect the electric organ discharges (EODs; 250–600 Hz) of conspecifics when they are superimposed over its own EOD. This study investigates the minimum frequency difference necessary for such signal perception, using the application of sine-wave stimuli. Electrosensory stimulusintensity thresholds were determined for trained fish using stimuli ...
