This study characterizes the artisanal fishery communities of Rio Grande do Sul state. The data were obtained at year 2001, with entities linked to sector and through participative methodologies. It was estimated that there are 12.201 fishermen distributed in 7 macro fishing areas average age is 42.9 years; 73% married 80% did not complete 1o degree; fisherwomen represents between 8 10% total. Fish consumed one four times a week (54% cases), an “per capita” consume 366.5 grams by meal,...
Several hypotheses are used to explain species richness patterns. Some of them (e.g. species-area, species-energy, environment-energy, water-energy, terrestrial primary productivity, environmental spatial heterogeneity, and climatic heterogeneity) known patterns organisms, especially when they combined. For aquatic however, it is unclear if these can be useful for purposes. Therefore, we a selection model approach assess the predictive capacity such hypotheses, determine which (combined or...
Abstract Humid highland forest enclaves are remnants of Atlantic Forest found in tablelands within the Caatinga biome (Northeastern Brazil), which emerged during interglacial periods Pleistocene. These ecosystems have a highly diverse and endemic fish fauna. Most earlier surveys focused on tableland Borborema (Pernambuco Paraíba States). In this study we surveyed fauna humid Ibiapaba Araripe, based samples collected rainy season (March April) between 2009 2014. The 45 sampling points covered...
The Cabiúnas Lagoon is a narrow water body that perpendicular to the sea and isolated from it by sandbank. Before 1991, sandbank was sometimes opened for few days local residents, but at present seawater only enters limited groundwater seepage or overtopping barrier in storms. In 1998 Restinga de Jurubatiba National Park established, including Cabiú nas Lagoon. Studies on structure spatial distribution of fish assemblage were performed between 1991 1994; we carried out one year (2001–2002)...
At the Sustainable Development Reserves of Mamirauá and Amanã, pirarucu fishery is co-managed. Local fishermen assess populations and, with help Institute state government, use this information to establish fishing quotas. Surveys are possible by counts individual coming surface breath air. This study reports preliminary findings population densities in areas within reserves based on time series built last years satellite im agery managed area. The increased most areas. increase rates for...
The effects of a disturbance by sandbank opening on the sh fauna community were evaluated through long-term study in Imboassica coastal lagoon, Rio de Janeiro State, Brazil. and salinity samples conducted between 1993 2004, with goal characterizing structure four openings this community, such as resilience resistance measurements. During three openings, years 1996, time could not be identied due to short period their magnitude discontinuity sampling. Monitoring studies previously indicated...
AIM: There is currently no consensus regarding the physical and chemical variability of tropical reservoirs. In semiarid Northeastern Brazil, reservoirs are among other things used for human consumption, industrial water supply intensive fish farming, all which can impact quality. The objective this study was to evaluate in Sítios Novos, a reservoir comparing samples collected areas tilapia (Oreochromis niloticus) farming from not directly impacted by aquaculture, both dry rainy season....
This research describes the influence of biotic and abiotic characteristics on fish fauna structure that inhabits stands aquatic macrophytes Eichhornia azurea crassipes. 182 individuals were sampled belonging to 27 species in Camaleão lake, Central Amazonia. Values dissolved oxygen water temperature varied from 2.11 4.02mgL-1 29.17 30.93ºC for E. crassipes, 1.29 2.59 mgL-1 28.32 29.95ºC azurea. The highest number (24), (134), biomass roots (1572gm-2) belonged Significantly differences among...
Aim:To evaluate possible nycthemeral and seasonal temporal patterns in fish assemblage associated with limnological aspects biotic factors two reservoirs semarid Northeastern Brazil.MethodsFish were sampled gillnets cycles throughout the dry rainy season (Paulo Sarasate/PS Edson Queiroz/EQ). The stomach contents of predator species surveyed. variables submitted to principal components analysis, while their relation abundance was determined by canonical correspondence analysis. Temporal...
Few studies have been published on the taxonomy, biology and ecology of fish fauna rivers reservoirs from Brazilian Caatinga. Considering importance surveys as subsidies for future fishing resources management, purpose present study was to assess assemblage two largest in middle Acaraú river basin, Paulo Sarasate Edson Queiroz reservoirs, state Ceará, Northeastern Brazil. Eight nycthemeral samplings were performed with gillnets (mesh size ranging 3 12 cm between opposite knots) during rainy...
Na ultima decada, a criacao de areas marinhas protegidas nas zonas costeiras aumentou consideravelmente. No entanto, e comum em diversos paises inexistencia ou pouca eficacia no processo planejamento participativo na destas unidades conservacao, o que pode ocasionar conflitos socio-ambientais, sobretudo com as comunidades tradicionais. Este estudo tem por objetivo analisar como percepcao ambiental pescadores artesanais contribuir para analise uma area marinha protegida (AMP) Nordeste do...
O presente estudo buscou identificar as funções desempenhadas pelo Parque Ecológico do Rio Cocó como área verde pública urbana de Fortaleza, Ceará, e analisou que forma essas contribuem para a melhoria da qualidade vida daqueles utilizam o espaço. Entrevistas realizadas por aplicação formulários, com 64 usuários parque, confirmaram importância dada pelas pessoas às áreas verdes em razão seu papel uma boa vida. A esta foram associados: "práticas esportivas atividades físicas"; "segurança...
Regiões de várzea apresentam alta produtividade biológica e são habitadas por populações que praticam atividades agropesqueiras, baseadas no uso múltiplo dos recursos. A economicidade do sistema conduz os ribeirinhos à apropriação territórios a dependência conjunta recursos ao estabelecimento acordos internos, definindo-se critérios acesso intensidades extração. Este estudo, meio 244 entrevistas com pescadores reuniões em 16 comunidades baixo Solimões, identificou fatores influenciam na...
A pesca é atividade essencial para as comunidades ribeirinhas da Amazônia, sendo o peixe fonte primordial de proteína animal e importante componente na geração renda.Devido às variações abundância distribuição das espécies como conseqüência do ciclo hidrológico região, ocorre sazonalidade pesca.Assim, este estudo teve por objetivo identi car quais fatores determinam tempo dedicação pescarias subsistência ou com ns comerciais, ribeirinhos áreas várzea.Foram entrevistados 244 pescadores 16 no...
O presente estudo analisa a influência dos componentes geoambientais e das intervenções antropogênicas nos movimentos de massa na sub-bacia hidrográfica do rio Pirapora, localizada no município Maranguape-Ceará. Estes processos morfodinâmicos subordinam-se, essencialmente, aos aspectos geológico-geomorfológicos, às condições hidroclimáticas, ao estado conservação fisionomia da vegetação, à geometria encostas ação antrópica, podendo condicionar eventos magnitudes variadas. Nessa perspectiva,...
Integrated analysis of geo environmental units related to fisheries in the south coast Espírito Santo, BrazilThis study aims present an integrated geoenvironmental activities Piúma, southern Santo state.The identification were accessed through referenced cartographical images, describing information about activities, uses and occupation, impacts management proposals
This study was conducted from January, 2012 to February, 2015 obtain the sustainability indexes of fisheries’ activities in Piuma county (Espirito Santo State, Brazil), through description fisheries systems using RAPFISH model - a method assessing with multivariate ordination analysis 54 attributes divided into five dimensions: social, ecological, economic, technological and management.
