Evaluar la efectividad de acciones de manejo en áreas protegidas del Gran Paisaje Yavarí Samiria es esencial para la conservación y el uso sustentable de la biodiversidad de la región. El objetivo de este trabajo fue evaluar el uso de modelos de ocupación, como herramienta para monitorear la efectividad de los acuerdos comunales de extracción de especies. De febrero a mayo de 2015, se establecieron 84 cuadrículas de 1km2 en el Área de Conservación Regional Comunal Tamshiyacu Tahuayo (ACRCTT), evaluando la ocupación de Tapirus terrestris (Linnaeus), Tayassu pecari (Link), Pecari tajacu (Linnaeus), Mazama sp., Cuniculus paca (Linnaeus), Dasyprocta sp., Dasypus sp. y Cracidae Vigors, a través de señales y rastros en transectos y estaciones de trampas-cámara. Se ajustaron modelos de ocupación single season-single species con covariables de sitio (CovS) para evaluar el efecto de...

Despite its importance in the local economy and food supply, the fishing carried out by riverside communities has been little studied. This paper presents the main characteristics of fishing in Lake Aripari based on the analysis of fish landing records. Between April 2018 and February 2019, species' richness and composition, landed biomass, catch per unit effort (CPUE) by hydrological periods, and the nutritional contribution of species destined for human consumption were evaluated. Forty-seven species were recorded, grouped into 23 families and 9 orders, with the Pimelodidae family being the most diverse (6 species). Species' richness was higher during the dry season, dominated by species of local migration and piscivorous habits. The total landings amounted to 10 650.7 kg, where 14 species accounted for 85.0% of the biomass. Sixty-seven percent of the biomass was for sale, with more th...

La pesca a pequeña escala, como la que se desarrolla en la cuenca del río Tahuayo (CRT), ha sido poco estudiada a pesar de su importancia como suministro de proteína para la región. En este trabajo se presentan las principales características ecológicas de la pesca en la CRT a partir del análisis del desembarque pesquero. Entre agosto 2016 y julio 2017, se evaluó la riqueza y composición de especies, biomasa desembarcada y capturas por unidad de esfuerzo (CPUE), por periodos hidrológicos, ambientes acuáticos y comunidades. Las capturas presentaron 62 especies, agrupadas en 23 familias y 7 órdenes, siendo la familia Pimelodidae la más diversa (12 especies). La riqueza de especies fue muy similar entre períodos hidrológicos y entre ambientes acuáticos. El desembarque total ascendió a 13805,38 kg, donde 17 especies representaron el 80,5% de la biomasa. Más del 50% de la bi...

Small-scale fishing, such as that of the Tahuayo river basin (CRT) has been little studied despite its importance as a protein supply for the region. This article presents the fisheries' main ecological features in the CRT based on of an analysis of fish landings. Between August 2016 and July 2017, the richness and composition of species, biomass and catches per unit of effort (CPUE) were evaluated, by hydrological periods, aquatic environments and communities. The captures presented 62 species, grouped into 23 families and 7 orders, with the Pimelodidae family being the most diverse (12 species). Species richness was very similar between hydrological periods and between aquatic environments. The total landing amounted to 13,805.38 kg, where 17 species represented 80.5% of the biomass. More than 50% of the biomass was landed in periods of...
