Abstract

In July 2010 and August 2011 a subadult and an adult porbeagle shark Lamna nasus were respectively caught as by-catch by an artisanal fishery boat using a gill net in the central Adriatic Sea. The specimens, a mature 200 and a maturing 150 cm total length male, were photorecorded, measured and identified on the basis of meristic traits. Such two occurrences are discussed in the context of recent and historical information available on the presence of this species in the Mediterranean Sea. Overall, data confirmed on the one hand the rarity of the porbeagle shark in the Adriatic Sea also, and, on the other hand, they suggested some relation between the density of the findings for this species and the presence of a pit zone in the central part of the Adriatic Sea.
