Life-history, ecology and fishery of Sepia officinalis in the western Mediterranean
MetadataShow full item record
Cephalopods constitute important resources for different Mediterranean fisheries such as trawl, artisanal and recreational fleets. Cuttlefish (Sepia officinalis) has been caught there from ancient times on and holds an important seasonal artisanal fishery in the Balearic Islands (western Mediterranean). This fishery takes advantage of the reproductive migration to coastal waters of large, mature individuals, even though the species is also taken by bottom trawlers throughout the year. In this study we used data from the following sources to analyze different aspects of cuttlefish biology, ecology and fishery in the western Mediterranean: 1) monthly biological and size samplings of individuals caught by artisanal boats (2007-08); 2) size samplings on board ofcommercial bottom trawlers (2001-11); 3) biological and size samplings on spring scientific surveys (2001-11); and 4) official fishery statistics from 1965 to the present. The main objectives of this study are twofold. First, ...
