Abstract

The present study aims to characterize the catch composition of the fishery for tunas in associated schools in the western equatorial Atlantic. For this purpose, a total of 109 landings on Areia Branca- RN, were observed, from June 2010 to May 2013, as well as on board in nine fishing cruises, from February 2011 to December 2012. The monitored fleet consisted of 9 boats, with an average length overall of 13.4 m. Landings amounted 691,533 kg (6,344.3 ± 292.7 kg), with a predominance of bigeye and yellowfin tunas, and other bycatch species, such as dolphinfish, blue marlin, skipjack tuna, wahoo, and rainbow runner. Occasionally, other species such as swordfish and triggerfish were also observed.
