A COMPARISON OF THE FISHERY BIOLOGY OF THREE ILLEX COINDETII VÉRANY, 1839 (CEPHALOPODA: OMMASTREPHIDAE) POPULATIONS FROM THE EUROPEAN ATLANTIC AND MEDITERRANEAN WATERS
International audience Three populations of the short-finned squid Illex coindetii were simultaneously sampled and studied from the Southern Celtic Sea and Bay of Biscay, Portuguese waters and Greek Seas, during a EU funded project (FAIR CT 1520). Dorsal mantle length (DML) ranged from 24 mm to 360...
