Note on a Juvenile Common Thresher Shark Alopias vulpinus (Bonnaterre 1788) in the waters of Slovenia (Northern Adriatic Sea)

A specimen of common thresher shark Alopias vulpinus (Bonnaterre 1788) was caught in a fishing net in the waters off Piran (Gulf of Trieste, northern Adriatic Sea). It was a juvenile male with a total length of 2841 mm. In recent decades, other cases of juvenile specimens of common thresher shark have been recorded in Slovenian coastal waters. Despite the drastic decline in the population of this species, thresher shark continues to be caught in local Adriatic fisheries.
