Caracterização da frota e do desembarque da pesca comercial no município de Coari, Amazonas, Brasil

Abstract

In the present study, the commercial fishing potential of the municipality of Coari, Amazonas, Brazil, was evaluated based on the characterization of the regional fleet and also by the fishing landing from the period of December 1st, 2007 to November 30th, 2008. The characterization of the fleet was based on the interview of 217 fishermen e vessel owners. They identified 41 boats and 176 motorized canoes. Among these, a pattern was found in their length (canoes ≤ 10m; boats ≤ 17m), fishing storage capacity (canoes ≤ 2t, boats ≤ 10t) and displacement capacity based on their engine propulsion power (canoe > 5,5HP; boat > 30HP). This information brought together estimates the region s fishing potential and its efficiency when this is crossed with the fishing landing in kilos. Other factors that contribute to the characterization of the activity are the exploited environment, the major tools used in fisheries and the target species. It was registered 311 landings near the municipal market (community commercial place) during the year. A total of 1.014.078 kg of fish was catched with a month average of 84,506 kg (+23,944), in which the maximum amount was 129,681 kg in May 2008 and a minimum of 55,884 kg in January 2008. An amount of 35 species or groups of species was registered. The major component species of the total catch were jaraqui (Semaprochilodus spp.) (26,90%), curimatã (Prochilodus nigricans) (14,07%), tambaqui (Colossoma macropomum) (9,70%) and aruanã (Osteoglossum bicirrhosum) (6,71%). This group was responsible for 57,38% of the total fish catched in the studied period.
