This volume includes 33 peer-reviewed papers presented at the Sixth Conference on Fish Telemetry held in Europe (Sesimbra, Portugal, 5-11 June 2005). The papers focus on migration and behaviour, species conservation and habitat rehabilitation, human impacts and fisheries, telemetry methodology and new technology. This book is aimed at scientists and engineers actively involved in aquatic telemetry projects.
