DO PHYSICAL INJURIES AFFECT ELECTROPERCEPTION? A CASE STUDY ON THE BRAZILIAN ELECTRIC RAY, NARCINE BRASILIENSIS (OLFERS, 1831)

Natascha Wosnick, Yuri Niella, Jorge Nunes, Carolina Freire

Resumo


The present study aimed to analyze the possible consequences of body deformities caused by fishing in the electroreceptive system of Narcine brasiliensis. Results demonstrated that the ability to detect low electrical stimuli was affected, as well as the ability to respond properly to higher signals. We discuss the results as they relate to ecological consequences, especially for benthic species that
