Is Iberian harbour porpoise (Phocoena phocoena) threatened by interactions with fisheries?
International audience Harbour porpoises in the Iberian Peninsula form a genetically distinct, small (around 2900 animals) and isolated population. Their main prey are commercially important fish, hence overlap between porpoise occurrence and fishing activity is almost inevitable. We compile informa...

International audience Harbour porpoises in the Iberian Peninsula form a genetically distinct, small (around 2900 animals) and isolated population.
