This study characterized fishing activity in the reservoir of the Hydroelectric Power Plant of Itá in Brazil. The reservoir is located in the Upper Uruguay River, which forms the border between the states of Santa Catarina and Rio Grande do Sul. To analyze fishing activity and the composition of ichthyofauna in the reservoir after damming, questionnaires were administered to fishermen in the region between 2004 and 2009. The results showed that fishing in the Itá reservoir can be classified as a subsistence activity performed on small vessels and usually involving the use of drift nets and handlines. Between 2004 and 2009, 292,780.10 . A total of 27 morphospecies were captured during the sample period; carp, traíra, mandi and jundiá together accounted for almost 60% of the catch. This finding indicates that fishing is centered on the capture of sedentary and short-distance migratory species. Despite their lower abundance, long-distance migratory species continue to be captured. The case of the piracanjuba, a long-distance migratory species reintroduced to the region in 2004 and still present in the catches, is particularly noteworthy. Regarding the fishermen's socioeconomic profile, all were men, most of who have engaged in the activity for more than eleven years, have a low educational level, fish with the aid of family members and list agriculture as their main economic activity. . Foram registrados os maiores valores de Captura Por Unidade de Esforço em 2006, com médias anuais de 9,69 kg pescador -1 dia -1 . Um total de 27 morfoespécies foram capturadas, com destaque para a carpa, a traíra, o mandí e o jundiá que juntas somaram quase 60% do total capturado ao longo do período estudado, indicando que a pesca está centrada na captura de espécies sedentárias e migradoras de curtas distâncias. Apesar da menor abundância, as espécies migradoras continuam sendo capturadas ao longo dos anos, em especial a piracanjuba, que foi reintroduzida na região em 2004 e que continua presente nas capturas. Em relação ao perfil socioeconômico, os pescadores são todos homens que em sua maioria, estão há mais de 11 anos na atividade, possuem baixo grau de instrução, desenvolvem a pesca com auxílio dos demais membros da família e têm a agricultura como principal atividade econômica.

“…Deslocamentos mais distantes do porto principal ou até mesmo das residências dos pescadores, número maior de dias de viagens, alta capacidade de armazenamento formam a dinâmica da pesca realizada por barcos de pesca na Amazônia (CARDOSO e FREITAS, 2007;GONÇALVES e BATISTA, 2008;ISAAC et al, 2008 Os valores de renda foram superiores aos observados por LIMA et al, 2012 em uma comunidade ribeirinha do médio rio Madeira (média mensal por expedição de R$ 465,00). Ainda assim, é necessário salientar que análises econômicas mais completas são difíceis de realizar, pois os registros não incluem despesas totais, como, a depreciação das embarcações e/ou dos apetrechos de pesca (PETRERE JR et al, 2006), bem como os rendimentos diários totais obtidos (KVIST et al, 2001).…”

RESUMOA pesca artesanal possui grande expressão socioeconômica na região Amazônica. Contudo há lacunas no conhecimento sobre a atividade em pequenos centros urbanos, especialmente em áreas de influência de empreendimentos. O estudo objetivou: avaliar e identificar características da pesca e comparar o esforço, custos e rendimentos da frota pesqueira do município de Humaitá, Amazonas. Analisou-se desembarques registrados pela Colônia de Pescadores e pela Universidade Federal de Rondônia, entre 2001 e 2013. A atividade é multiespecífica e praticada em pequenas embarcações, canoas (média 7,53 metros) e barcos de pesca (média 11,5 metros). A produção variou entre 178 t e 298 t, CPUE média mensal entre 10 e 43 kg pescador dia -1 e a renda mensal entre R$ 397,50 e R$ 2.375, para canoas motorizadas e barcos de pesca, respectivamente. Diferenças entre tipos de embarcações e características na atividade com outras regiões da bacia do rio Madeira reforçam a necessidade de monitoramento e estratégias de gestão diferenciadas.Palavras chave: atividade pesqueira; esforço de pesca; frota pesqueira; custos SMALL-SCALE FISHING AT HUMAITÀ MUNICIPALITY, MIDDLE MADEIRA RIVER, AMAZONAS, BRAZIL ABSTRACTThe artisanal fishing has socioeconomic expression in the Amazon region. There are gaps in knowledge about this activity in small urban centers, especially in areas with influence of projects. The study aimed to assess and identify the characteristics of this activity and compare the effort, costs and revenues of the fishing fleet in the municipality of Humaitá, Amazonas. We analyzed landings recorded by Colony of Fisheries and the Federal University of Rondônia, between 2001 and 2013. The fishing is multi-species and is practiced in small boats, canoes (mean 7.53 m) and fishing boats (mean 11.5m). The production varied between 178t and 298 t, monthly CPUE was 10 and 43 kg fisherman day -1 , and the income was R$ 397.50 and R$ 2.375 for motorized canoes and fishing boats, respectively. Differences between types of fleet and the characteristics in the activity compared to other regions of Madeira River Basin reinforce the need for monitoring and differentiated management strategies.

“…The campaigns consisted of visits to different fishing communities, where the fishers present at the site were interviewed and indicated others to be interviewed later, according to the "snowball" methodology (Camargo and Petrere (2001), Cetra and Petrere (2001), Ceregato and Petrere (2003) and Petrere et al (2006). The data were Table 1 also presents the periods of higher catches per species.…”

Small-scale fishers use a wide range of gear and fishing techniques, catching large quantities of fish (Salas et al., 2007). The operation of the small-scale fishing fleet is constrained by environmental characteristics and the seasonal behaviour of the exploited resources.In Florianopolis, various types of fishing gear are found, with a predominance of gillnets (anchorage, driftnet, etc.), as well as zangarilho to catch squids and beach seine IntroductionFishing activity may be considered as the combination of different interacting components, including man, natural resources and management systems, influenced by internal and external factors. As such, fishing is composed of a group of interrelated activities, including capture, fish processing, the market and the consumer's demand for fish, operating on certain socioeconomic and political contexts (Salas and Gaertner, 2004 AbstractThe objective of this paper is to describe the main characteristics of small-scale marine fisheries in the municipal district of Florianópolis (SC), the capital city of the state of Santa Catarina. We give information about the most captured species, the fishing fleet and fishing gear used. The dynamics of the activity is described, considering the kind of operation of the boats, alongside post-capture procedures. The analyses were accomplished in two types of fishing communities: the one composed of fishers that fish in bays (North and South) and those who fish in the open sea. Numeric differences were observed among these two fishing areas, indicating the existence of two different fleets operating in the area. Differences between the two fishing areas were detected, considering the species caught, the harvest time and the fishing gear used. The open sea fishers have boats with dimensions, engine power, number of crew and fuel consumption numerically higher than those working in bays, indicating the existence of two distinct fleets operating in the region.Keywords: marine small-scale fisheries, fishing dynamics, fishing gear, harvest season, Florianópolis. Pescarias marinhas de pequena escala no município de Florianópolis, Santa Catarina, Brasil ResumoEste trabalho teve como objetivo caracterizar a pesca de pequena escala no município de Florianópolis (SC). São apresentadas informações sobre as principais espécies capturadas, sobre a frota e artes de pesca utilizadas, sobre a dinâmica da atividade, considerando a forma de operação das unidades produtivas, e sobre os procedimentos pós-captura adotados. As análises foram realizadas em dois tipos de comunidades pesqueiras: as compostas por pescadores que atuam em baías e aquelas cujos integrantes pescam em mar aberto. Foram detectadas diferenças entre as duas áreas de pesca considerando as espécies capturadas, as épocas de captura e as artes de pesca utilizadas. Os pescadores de mar aberto possuem embarcações com dimensões, potência dos motores, número de tripulantes e consumo de combustível numericamente superiores aos que atuam nas baías, indicando a existência de duas frotas dist...
