Abstract


Atlantic bluefin tuna (Thunnus thynnus (Linnaeus, 1758)) (ABFT) and swordfish (Xiphias gladius Linnaeus, 1758) are pelagic, migratory species, with high economic value. They are currently heavily exploited. Many recent works have shown the importance of knowing the spatial distribution of these species. This study presents an important and unique database of these species catch distributions observed during tunaye fishery in the Northwestern Mediterranean Sea in 2000-2003 and achieved by a concerted effort of the fishermen and the scientific team on 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 founded by the Council of the “Région Provence-Alpes-Côte d’Azur”. Imbert et al. (2001, 2002, 2007) published and analysed only 20% of the fishery records, corresponding to the scientific database only. The present article presents the entire database.
