This paper gives an update of recent data and analyses of cetacean strandings from the Bay of Biscay in the aim of identifying candidate fisheries involved in the associated bycatch. Firstly, it provides a short synthesis of recent stranding data in the Bay of Biscay for the years 2016-2019 compared to the period 1990-2015. Secondly, an analysis of spatial co-occurrence of mortality areas, obtained by dolphin carcass reverse drift calculation, and fishing effort distributions split by mÃ©tiers (fishing gear/target species) is given for the multiple stranding event of the year 2017, and further extended over the period 2006-2015.
