one specimen of wahoo, acanthocybium solandri was caught in june 2004 by artisanal fishermen in the straits of messina, sicily. this epipelagic species has a circum-tropical distribution and in the mediterranean has been recorded only twice. meristic characteristics, gonads and stomach contents were analysed. two species of parasites, the giant trematodes hirudinella ventricosa and the monogenean neothoracocotyle acanthocybii were detected in the stomach and in the gills, respectively. the presence of these helminths, typical of hosts captured in atlantic and pacific waters is consistent with the migration of this specimen via gibraltar.
