A pesca artesanal com espinhel de fundo na Plataforma Continental Amazônica

Abstract

The longline is a passive fishing gear and provides little impact on the ocean floor. The bottom longline fishery on the Amazon coast was characterized with respect to the vessel used, work, fishing effort and species caught. The data collection was carried out in loco on the longline fishing vessels of the artisanal fleet of Bragança-PA for 15 bids, distributed in three fishing areas. The vessel is classified as small size, has the necessary equipment for navigation and specific structures for the development of the tasks on board. The baits are obtained by means of exchange with medium sized vessels. During the launch and gathering of the longline, 2,600 hooks are baited on average per bids. The catches on the amazon continental shelf have high fish diversity, with catfish and sharks showing the highest abundance indexes. More than half of the shark caught in bottom longline was adults, suggesting a high selectivity of this fishing gear indicating a potential for more sustainable fishing.
