This European Standard describes a standardised method for sampling fish in lakes, using multi-mesh gillnets. The method provides a whole-lake estimate for species occurrence, quantitative relative abundance and biomass expressed as Catch Per Unit Effort (CPUE), and size structure of fish assemblages in temperate lakes. It also provides estimates, which are comparable over time within a lake and between lakes. This document provides information on sampling routines, data handling and reporting, sampling of fish for ageand growth analyses as well as applications and further treatment of data. A selected literature with references in support of this standard is given in the bibliography
