Abstract
SUMMARY After a period of major decrease throughout the 1990s and 2000s, the fishing effort of the French purse seine fishery has been increasing since 2008. In 2010, the fleet was characterized by 10 purse seiners that represented a total carrying capacity of almost 9,000 GRT and made more than 2,000 fishing sets. Fishing on free swimming schools predominates in the fishery but the percentage of sets on log-associated schools has been increasing in recent years to reach 40% in 2010. Total catches were about 37,000 t in 2010 and composed of 54%, 38%, and 8% yellowfin, skipjack, and bigeye, respectively. Estimates of by-catch, by-products, and discards of the French purse seine fishery were derived from the combination of a large dataset of French and Spanish observer data and are given by fishing mode for large taxonomic groups.
