Abstract


Large-scale driftnets were used in the Mediterranean sea till 2007 and caused by-catch, one of the most significant issues affecting fisheries management. Recent international programmes focused on these species and on the importance of knowing their spatial and temporal distribution, and interactions with fisheries activities. This paper presents a database of non-target (Auxis rochei rochei, Brama brama, Coryphaena hippurus, Euthynnus alletteratus, Katsuwonus pelamis, Lichia amia, Luvarus imperialis, Polyprion americanus, Sarda sarda, Tetrapturus belone, Thunnus alalunga, Alopias vulpinus, Isurus oxyrinchus, Prionace glauca, octopuses and cuttlefish) and released alive (Mola mola, Pteroplatytrygon violacea, Mobula mobular, Caretta caretta) by-catch species observed between 2000 and 2003 during driftnet fishery targeting primary Atlantic bluefin tuna (Thunnus thynnus) in the Northwestern Mediterranean sea. Created by a concerted effort between the fishermen and the scientific team from the “Centre d’Océanologie de Marseille”, the database, composed of 2393 fishery reports concerning 51 fishing boats and validated by 74 scientific observers, was realised for an expertise funded by the Council of the “Région Provence-Alpes-Côte d’Azur”.
