| Between the 1st of February and the March 31, 2017, 793 stranded cetaceans were found along the French Atlantic coasts. Common dolphins made up 84% of these strandings, and most of these presented evidence of death in fishing gear. The aim of this work is to test an approach that could help identify the fisheries potentially involved in a given stranding event. To do this we examined how the distributions of likely areas of mortality of bycaught dolphins, inferred from carcass drift modelling, coincide with fishing effort statistics of various fleets, generated from the Vessel Monitoring System, in the area over the same dates. Using reverse drift modelling, two main mortality areas were identified. A total of 3690 common dolphins (IC95% [2230; 6900]) were... |

| This preliminary study of whales and dolphins off the French Mediterranean coasts refers to 15 spp, 11 Odontoceti and 4 Mysticeti: 3 of them are common; Delphinus delphis, Tursiops truncatus and Ziphius cavirostris (in the Ligurian sea), 2 are frequent in the Ligurian sea: Grampus griseus and Balaenoptera physalus, 3 are not uncommon: Stenella coeruleoalba, Globicephala melaena, and Physeter macrocephalus, 2 are rare: Pseudorca crassidens and Orcinus orca, 3 are exceptional: Balaena acutorostrata, Megaptera novaeangliae, and Steno bredanensis, 2 seem doubtful: Hyperoodon ampullatus and Balaenoptera musculus. Also important is the fact that no Phocoena phocoena has been observed. More generally, whales and dolphins seem to be more abundant in the area... |

| La présente étude réalisée, de Juin à Novembre 2010 a porté sur l’expérimentation de l’efficacité d’un appareil acoustique, à dissuader le grand dauphin Tursiops truncatus de s’approcher des senneurs lors des opérations de pêche des petits pélagiques dans la région de Kélibia. Les opérations de pêche à la senne sans recours aux Pingers ont révélé une fréquence d’avaries des filets bien supérieure à celle des bateaux équipés de pingers. Les pingers testés ont fait donc preuve d’une efficacité technique moyenne de l’ordre de 19,85%. Cette efficacité technique est jugée douteuse |
