“The Guardia Military has seized 53 tons of blue shark that were in transit through the port of Leixões and were caught by a Portuguese vessel in the South Atlantic Ocean,” the GNR said in a statement.
The fish raised suspicions about compliance with CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) and illegal fin trimming.
