Description
Summary:The aim of this study was to obtain a better understanding of the exploitation pattern of the European lobster population in a fully representative small-scale fishery of the Mediterranean (Corsica, France) and to collect initial biological information on this species. Data were collected by scientific observers on board net fishing vessels for eight consecutive years from 2006 until 2013. Average annual catches were estimated at 6.7 t. Length frequencies indicated that exploitation focused on large individuals. Catch per unit of effort varied significantly as a function of month, fishing area and depth. Our approach to catch distribution revealed spatial heterogeneity with large catches in the south area. A fishery-independent survey was performed in 2013 and 2014 in west Cap Corse using 540 lobster traps; it showed an extremely low catch rate, confirming the low abundance for this area. This study provided new biological knowledge of a little-studied species in the Mediterranean.
