Dinâmica espaço-temporal da frota de pequeno porte em um Polo Pesqueiro do Litoral Amazônico Brasileiro

Abstract

In Amazon area, estuarine-marine fishing performed by the artisanal fleet has great representation in the production chain. We analyzed the displacement of small boats (BPP) operating from Vila dos Pescadores, Bragança-PA, between the years 2004 and 2015. Data of landings, days and fishing gear, number of fishermen and area of operation were obtained. Two types of nets were observed, the “serreira” gillnet and the “gozeira” gillnetnet. Crews ranged from four to five fishermen, while fishing days lasted around five days, with an average of 25 trips per year. It was visualized that the BPP fleet presented two behaviors. Between 2004 and early 2013, fishing was concentrated in the gravel fishing ground, 30 to 40 nautical miles away from the Vila dos Pescadores. Later, in 2013, fleet migration occurred, with 2015 being the year of greatest concentration to the “boias” fishing grounds, distant 80 to 90 miles. With fishing concentrated specifically in the “boias” fishing ground, there were significant reductions in the average annual production, indicating repetition of the decline in fish stocks. Changes in fishing area and target species interfered with the dynamics of displacement of the local fleet.
