Electric organ discharge displays during social encounter in the weakly electric fish Brienomyrus niger L Mormyridae



Electric organ discharge displays during social encounter in the weakly electric fish Brienomyrus niger L Mormyridae



Ethology 82.3: 177-191



The authors investigated the electric organ discharge (EOD) activity of the mormyrid fish Brienomyrus niger during social encounters. The fish were contained in porous ceramic shelters and tested alone and in pairs in an experimental tank designed to restrict communication to the electrosensory modality. The authors moved one fish toward and away from a stationary conspecific, beginning at a distance known to be outside the range of communication (250 cm). Baseline EOD activity was recorded prior to interaction and categorized as "variable", "regular", and "scallop". When moved closer together, the fish modulated this baseline activity in four ways.
