Abstract


The archipelago of Fernando de Noronha comprises two protected areas managed by ICMBIO (Chico Mendes Institute for Biodiversity Conservation). Currently, tourism is the main economic activity, however, fishing is still an important means of interaction between human populations and the environment. This study aimed to characterize artisanal fisheries in relation to the composition of fish and fishing strategies used. Data were collected by sampling daily fish landings occurred from April to September 2013. We analyzed 250 landings where the average fisheries was 10 hours and the predominant technique was the “hook and line” observed in 98.8 % of landings with the use of bait, and sardine most commonly used (91.6%). Landings sampled resulted in 23748.5 kg, distributed in 22 species. The most representative was the “albacora” (Thunnus albacares) present in 70.8 % of samples, with 7142.5 Kg, 30.1 % of the total biomass caught. Fish species such as king (Elagatis bipinnulata), “Xaréu preto” (Caranx lugubris) and “Barracuda” (Sphyraena barracuda) were present, respectively, 58.8 %, 56.8 % and 55.2 % of the landings. Data fisheries productivity are important for spatial fishing in protected areas of Fernando de Noronha, and provides important information for ichthyological studies in the region.
