Management and ecology of the wedge clam (Donax trunculus) in the NW Mediterranean Sea: The case of Ebro Delta (NE Spain)

The wedge clam (Donax trunculus) is one of the most prized clam species fished in the EU. Clam fisheries have experienced a dramatic decline during the last decades on Spanish coasts resulting in the progressive closure of fishing grounds. The Ebro Delta (NW Mediterranean Sea) is one of the few area...
