Resumo: | Here we present an update of the aerial surveys that have been carried out by IFREMER in the western Mediterranean Sea since 2000. This collection of data enables the monitoring of the bluefin juvenile population since the Gulf of Lyon is considered as a nursery for young individuals. The detections of juvenile bluefin tuna are carried out along the same transects between 2000-2003 and then 2009-2011 and are used to calculate a fishery-independent index of bluefin tuna abundance. This index can therefore be included in the stock assessment procedure as an abundance index of juveniles.
