ResumenDamselfish, Stegastes fuscus, is a common fish species in the Brazilian waters being considered an ecological key species in reef habitats. One hundred and sixty six adults, ranging from 70 to 120 mm of standard length, were collected in April 2013 by spear fishing in six coastal islands located on Cananéia, Paranaguá, Guaratuba and Babitonga bays, southeast Brazil. A combination of otolith shape indices (circularity, aspect ratio, roundness and solidity) and elliptic Fourier descriptors were analysed by standard multivariate statistical procedures. This study intent to investigate whether otolith shape can be used to differentiate S. fuscus populations, providing new knowledge to a rational management of this species
