“…The values of CPUE found in this study were lower than those reported in [18] for the Middle Solimões River region (40.0 to 80.0 kg/fisherman/day) and in [19] for the municipality of Guajará-Mirim (65.0 kg/fisherman/day). However, they were similar to the values reported in [17] for Manicoré (22.9 and 20.6 kg/fisherman/day for fishing boats and small boats with outboard motors, respectively) and in [19] for Teotônio (26.6 kg/fisherman/day) and slightly above the values reported in [12] for Santarém (15.0 kg/fisherman/day).…”

The purpose of this study was to gather information about fish landings in Barcelos, in the Middle Rio Negro region. Data were collected from fishing boats at weekends and from stalls where fish were processed and sold during the week. The results showed that in the period from February 2012 to January 2013, 56.0 tons of fish were landed and that average landings were 3.6 ± 2.2 tons/month and 1.1 ± 0.7 tons/month for fishing boats and for small boats with outboard motors, respectively. Pacu (subfamily Myleinae), aracu (family Anastomidae) and tucunaré (Cichla spp.) were the main species caught and accounted for approximately 50% of the landings. The Demeni River, Lake Anauali and Zamula streamlet were the most exploited fishing areas. Fishing boats exploited the lakes in the dry and flood seasons and the rivers in all seasons of the hydrological cycle, with a slight predominance in the falling-water season. Streamlets were also exploited by fishing boats in all the seasons apart from the flood season. Lakes were the preferred environment for small boats with outboard motors in the dry season. While rivers were exploited by these boats throughout the year, streamlets were exploited mainly in the rising-and fallingwater seasons. There was a decrease in fishing effort in the flood season and an increase in the dry season. Average CPUE was 21.9 and 23.9 kg/fisherman/day for fishing boats and for small boats with outboard motors, respectively.

“…Isso confirma a demanda do mercado local e a pressão que as mesmas espécies vêm sofrendo com o passar do tempo, o que é atestado pela sua presença constante em estudos de desembarque pesqueiro na Amazônia brasileira (PETRERE Jr., 1985;BARTHEM, 1995;PETRERE Jr., 2003;BATISTA et al, 2012;DORIA et al, 2012;ALCÂNTARA et al, 2015).…”

ResumoFoi registrado o uso de recursos pesqueiros pelos moradores da cidade de Santarém-PA, no baixo rio Amazonas, e analisados os aspectos associados à evitação ou ao incremento de seu consumo. Os dados foram coletados mensalmente nos mercados e feiras, mediante a aplicação de questionários semiestruturados junto a consumidores e comerciantes de pescado, entre agosto de 2013 e julho de 2014. Os dados foram armazenados em um banco de dados relacionais e submetidos à estatística descritiva. O peixe foi o principal produto adquirido e comercializado (80% dos entrevistados). Atualmente, preferem o tambaqui e o tucunaré -e não o acari e a pescada, que eram os preferidos antigamente. O tabu tradicional contra o consumo de peixes lisos ainda existe, mas algumas espécies que antes não eram consumidas ou pouco consumidas estão sendo aceitas e encontradas nos mercados. AbstractThe use of fishing resources by the residents of the city of Santarém-PA in the lower Amazon was recorded and were analyzed the avoidance or the increase of consumption. Data were collected monthly in the markets and fairs, through the application of semistructured questionnaires to consumers and fish merchants between August 2013 and July 2014. The data were stored in a relational database and submitted to descriptive statistics. The fish was the main product purchased and sold (80% of respondents). Currently tambaqui and the peackok tucunaré are the prefered fish and not the acari and the freshwater hake that were formerly preferred. The traditional taboo against the consumption of catfish still exists, but some species that were not consumed or little consumed are currently being accepted and available on the market.

“…In contrast with other regions of the Amazon basin, the fishing fleet of the Xingu is dominated by a large number of wooden canoes powered by "long-tail" outboard motors, which work independently (Cardoso and Freitas, 2007;Isaac et al, 2008;Doria et al, 2012). Larger ice packer motorboats are rare.…”

“…The harvesting of these species is influenced by the hydrological cycle, which is the primary regulator of the whole ecosystem, and has a direct influence on yield. The target species shift according to a calendar which allows for high yields throughout practically the whole year, guaranteeing both subsistence and incomes (Batista and Petrere Junior, 2003;Barthem and Fabré, 2004;Gonçalves and Batista, 2008;, Doria et al, 2012.The present study revealed that more than 60% of total catches are related to the capture of five species groups, three of which (curimatã, aracu, and pacu) have periods of breeding and recruitment strictly linked to the river's flood pulse (Camargo and Lima Junior, 2007;. Modifications of the dynamics of this process will inevitably affect the abundance of these species in the future reservoirs, resulting in major shifts in the composition of the community.…”

Artisanal fisheries of the Xingu River basin in Brazilian Amazon

et al. 2015

The present study characterises the commercial fisheries of the basin of the Xingu River, a major tributary of the Amazon River, between the towns of Gurupá (at the mouth of the Amazon) and São Félix do Xingu. Between April, 2012, and March, 2014, a total of 23,939 fishing trips were recorded, yielding a total production of 1,484 tons of fish, harvested by almost three thousand fishers. The analysis of the catches emphasizes the small-scale and artisanal nature of the region's fisheries, with emphasis on the contribution of the motorised canoes powered by "long-tail" outboard motors. Larger motorboats operate only at the mouth of the Xingu and on the Amazon. Peacock bass (Cichla spp.), croakers (Plagioscion spp.), pacu (a group containing numerous serrasalmid species), aracu (various anostomids), and curimatã (Prochilodus nigricans) together contributed more than 60% of the total catch. Mean catch per unit effort was 18 kg/fisher, which varied among fishing methods (type of vessel and fishing equipment used), river sections, and time of the year. In most cases, yields varied little between years (2012 and 2013). The technical database provided by this study constitutes an important resource for the regulation of the region's fisheries, as well as for the evaluation of future changes resulting from the construction of the Belo Monte dam on the Xingu River.Keywords: fish production, fishers, fishing effort, fishery yield. Pescarias artesanais da bacia do Rio Xingu na Amazônia Brasileira ResumoEste trabalho teve como objetivo caracterizar a pesca comercial de consumo na bacia do rio Xingu, afluente do rio Amazonas, no trecho entre a cidade de Gurupá (localizada na foz do Rio Amazonas) até São Félix do Xingu, no estado do Pará, Brasil. No período de abril de 2012 a março de 2014 foram registradas 23.939 viagens de pesca, totalizando uma produção de 1.484 toneladas de pescado, obtidas por quase 3.000 pescadores. A análise dos dados oriundos do monitoramento dos desembarques demonstrou que a pesca na região tem caráter artesanal de pequena escala, destacando-se a participação de canoas motorizadas que utilizam um motor de popa chamado "rabeta". Os barcos motorizados atuam somente na foz do rio Xingu e no rio Amazonas. Tucunaré (Cichla spp), pescada-branca (Plagioscion spp), pacu (várias espécies de Serrasalmidae), aracu (várias espécies de Anostomidae) e curimatã (Prochilodus nigricans) perfazem mais de 60% do total capturado. A captura média por unidade de esforço é de 18 kg.pescador -1 .dia -1 e muda dependendo da modalidade de pesca (tipo de embarcação e arte de pesca), do pesqueiro utilizado e da época do ano. Na maior parte dos casos, não encontramos diferenças nos rendimentos de 2012 e 2013. As informações técnicas geradas são importantes para subsidiar ações de ordenamento pesqueiro, bem como para avaliar futuras mudanças que possam ocorrer na atividade frente à construção da barragem de Belo Monte no Rio Xingu.Palavras-chave: produção pesqueira, pescadores, esforço de pesca, rendimentos pesqueiros.
