The idea was to improve the knowledge available on the spawning areas of European seabass (Dicentrarchus labrax) in the northeast Atlantic. To do so, we characterized the seabass spawning areas along the French Atlantic coast (English Channel and Bay of Biscay) using fishing data from geolocated vessels (VMS data provided by the Direction des Pêches Maritimes et de l'Aquaculture (DPMA) and the Système d'Informations Halieutiques (SIH) of Ifremer). A non-linear geostatistical approach was carried out over the years 2008-2013 to detect areas where seabass aggregate to reproduce. Spawning areas occurrence maps were produced for each month of the spawning season. These occurrence maps were summarised in average maps representing the probability of being a spawning area. These maps allow quantifying the seasonal and interannual variability, and highlight the recurrent, occasional and unfavourable spawning areas. An average map over all months of the spawning season was also produced to summarise the results and simplify the use.
