“…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).…”

“…Fishing effort is reduced during the flood period, unlike in the Madeira River, where fishermen in fishing boats and small boats with outboard motors increase fishing effort during the rising-water and flood periods to make up for the smaller yield during these less productive periods [17]. The reduction in fishing effort for vessels in Barcelos when the water level is higher may be related to dispersion of shoals, making it more difficult to catch the fish.…”

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.

“…The results of the present study reinforce the importance of maintaining the original hydrological and environmental conditions of the river as intact as possible on at least some stretches (Barthem, 1999;Batista and Petrere Junior, 2003;Isaac et al, 2004;Viana, 2004;Cardoso and Freitas, 2007), given that the main river channel is the principal fishing ground, and that the proposed dam will impact the hydrological cycle and level of the river over a stretch of more than 200 km between the town of Altamira and the Great Bend. In particular, effective conservation and management strategies for the sectors of the river upstream from Altamira must be prioritized and implemented as soon as possible, with adequate resources to ensure the effectiveness of this process.…”

“…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 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.

1 ADRIANO AMIR DIDONET 2, ISOLDE DOROTHEA KOSSMANN FERRAZ 3 RESUMO -Tucumã é uma palmeira amazônica. A polpa dos frutos é comestível sem cozimento e muito apreciada como recheio de sanduíches na culinária regional, possui alto valor nutritivo e destaque no teor de vitamina A. O presente estudo teve como objetivo avaliar aspectos da comercialização dos frutos e da polpa de tucumã em feiras e mercados de Manaus. Durante o estudo de um ano, foram levantadas as procedências e preços dos frutos e estimada a quantidade comercializada em seis feiras e mercados de Manaus. Os dados de procedência, quantidade, preço e outras informações relacionadas foram obtidos através da aplicação mensal de um questionário semiestruturado aos comerciantes. O preço real e sua evolução histórica, desde 1995, foram deduzidos por comparação com estudos anteriores. Entre maio de 2011 e abril de 2012, os frutos foram provenientes de 20 diferentes localidades a uma distância de até mil km de Manaus. Os locais mais citados foram os municípios de Itacoatiara, Terra Santa, Rio Preto da Eva, Autazes e a bacia do Rio Madeira. A alternância das procedências garantiu o abastecimento contínuo ao longo do ano. Entretanto, uma redução do número de procedências e da quantidade de frutos comercializados foi verificada entre setembro e novembro. A sazonalidade da oferta foi refletida nos preços dos frutos e da polpa. Durante os 12 meses, foi comercializado um total de 367,8 toneladas de frutos, com 30,7 toneladas de média mensal. Cerca da metade (53%) desta quantia foi descascada durante a jornada de trabalho dos feirantes e comercializada apenas a polpa. Neste estudo e baseado em informações anteriores, tucumã foi sempre um dos frutos mais caros dos mercados de Manaus. Entre 1995 e 2012, os valores reais aumentaram substancialmente, tanto da saca (230%), com cerca de 41 kg, como da dúzia de frutos (316%) e do kg da polpa (253%). Os resultados indicam que o mercado de tucumã continua em expansão. Aparentemente, a demanda é maior do que a oferta e, dessa forma, há necessidade de aumento da produção.

Mey -ARECACEAE) AT LOCAL MARKET-PLACES IN MANAUS (AMAZONAS, BRAZIL)ABSTRACT -Tucumã is an Amazonian palm tree. The raw pulp of the fruit is edible and highly appreciated as sandwich filling in local culinary. The pulp of high nutritional value has significant vitamin A content. This study aimed to evaluate aspects of the trade of tucumã fruit and pulp at fairs and markets of Manaus. During the one-year study, the provenances and price variation of the fruits were registered and estimated the amount delivered to six markets and fairs of Manaus. Data on provenance, quantity, value, and related information were obtained by applying monthly a semi-structured questionnaire to the salesmen. The real price and its historical evolution since 1995 were deduced by comparison with previous studies. Between May 2011 and April 2012, t...
