Flock of seagulls fly near Danilo Latin's ship in Savudrija
A flock of seagulls fly near Danilo Latin's ship in Savudrija June 26, 2013. Most of the 3,700 fishermen who ply their trade in Croatia's eastern Adriatic fear that the country's accession to the European Union on July 1, and strict new laws and regulations that come with it, may drive the last nail into their coffin. Croatia's Adriatic is small and relatively shallow and fishermen use traditional nets that are not compliant with the Common Fishing Policy, modeled mostly on fishing in the Atlantic.
