The concept of "reference conditions" describes the benchmark against which current conditions are compared when assessing status water bodies. In this paper we focus on establishment reference for European lakes according to a phytoplankton biomass indicator—the concentration chlorophyll-a. A mostly spatial approach (selection existing with no or minor human impact) was used set chlorophyll-a values, supplemented by historical data, paleolimnological investigations and modelling. work...
Adapting and adopting River Habitat Survey: Problems solutions for fluvial hydromorphological assessment in PortugalThe Water Framework Directive (WFD), which established the use of quality elements to assess ecological status water bodies, has influenced purpose content several European methods characterizing physical structure assessing habitat rivers.The Survey (RHS) is a WFD compliant method developed UK follows rapid simple survey procedures using standardised approach characterize...
River fragmentation by large hydropower plants (LHP) has been recognized as a major threat for potamodromous fish. Fishways have thus built to partially restore connectivity, with fish lifts representing the most cost-effective type at high head obstacles. This study assessed effectiveness which lift in LHP on Lima (Touvedo, Portugal), allows fish—Iberian barbel (Luciobarbus bocagei), Northern straight-mouth nase (Pseudochondrostoma duriense) and brown trout (Salmo trutta fario)- migrate...
Abstract Many types of fish passage facilities have been built worldwide to mitigate river fragmentation by instream barriers and partially restore upstream movements fish. Among these, lifts are a design that enables pass through high‐head obstacles (>15 m height) can be considered the most cost‐effective fishway. However, fishways may also used non‐native invasive species disperse impact new areas organisms upstream. As far as authors aware, this short communication is first record red...
Water quality determines the success or failure of fish researches. A series rectangular concrete tanks covered with nylon nets were evaluated as a pattern for conduction essay aquatic animals, when environment conditions must be same. Physical and chemical characteristics water observed. The populated ten juvenile pacu ( Piaractus mesopotamicus ) which fed ad libitum twice day. experiment was carried out between November February 1992/1993. In middle five fishes slaughtered in order to keep...
O processo de gestão da qualidade água das albufeiras águas protegidas localizadas em Portugal continental é, grande parte, consubstanciado pela implementação medidas inscritas nos principais instrumentos do território, nomeadamente os Planos Gestão Região Hidrográfica (PGRH) e Ordenamento Albufeiras (POA), actualmente designados Programas Especiais Águas Públicas (PEA), função adaptação dos POA ao quadro legislativo vigente. A definição disposições gerais relativas uso ocupação área...
