Water quality - Sampling of fish with multi-mesh gillnets

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 fish 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 European Standard provides information on sampling routines, data handling and reporting, sampling of fish for age and growth analyses as well as applications and further treatment of data. Selected references in support of this European Standard are given in the Bibliography.

Wasserbeschaffenheit - Probenahme von Fisch mittels Multi-Maschen-Kiemennetzen

Diese Europäische Norm beschreibt ein genormtes Verfahren zur Probenahme von Fischen in Seen mit Multi-Maschen-Kiemennetzen. Dieses Verfahren liefert Daten zur Abschätzung des Artenspektrums im gesamten See, eine quantitative Abschätzung der relativen Artenhäufigkeit sowie der Biomasse, ausgedrückt als Einheitsfang (Catch Per Unit Effort, CPUE) und der Größenverteilung von Fischbeständen in Seen gemäßigter Zonen. Weiterhin liefert sie Abschätzungen, die für zeitliche Vergleiche innerhalb eines Sees und zwischen verschiedenen Seen geeignet sind. Diese Europäische Norm stellt Informationen für routinemäßige Probenahmen, den Umgang mit Daten und deren Protokollierung, die Probenahme von Fischen zur Alters- und Wachstumsbestimmung sowie Anwendungsmöglichkeiten und weitere Datenbehandlung zur Verfügung. Im Literaturverzeichnis sind ausgewählte Arbeiten angegeben, die direkten Bezug zur Anwendung dieser Europäischen Norm haben.

Qualité de l'eau - Echantillonnage des poissons à l'aide de filets maillants

La présente Norme européenne décrit une méthode normalisée pour l'échantillonnage des poissons dans les lacs, à l'aide de filets maillants multimailles. La méthode fournit une estimation, à l'échelle d'un lac, de l'occurrence des différentes espèces, de leur abondance relative, numérique et pondérale, exprimée en capture par unité d'effort (CPUE), et de la structure en taille des peuplements de poissons dans les lacs tempérés. Elle fournit également des estimations comparables dans le temps au sein d'un même lac ou entre plusieurs lacs. Elle donne aussi des informations concernant les routines d'échantillonnage, le traitement et la communication des données, l'échantillonnage des poissons en vue de l'analyse de l'âge et de la croissance, ainsi que les applications et le traitement ultérieur des données. La bibliographie présente une sélection d'ouvrages se rapportant à cette norme.
