The highest catch per uniteffort (CPUE) value (66.8kg h-1 ) was registered in September when the fishing seasonwas opened and decreased with the lowest value occurring in March (12.5kg h-1). Theaverage CPUE was 26.3±18.9kg h-1. The fishes represented the highest proportion(79.10%) of the total catch (631.4kg), followed by crustaceans (13.73%), and lastlycephalopods (7.17%).
