BS EN 14011 is a standard that serves technical specifications for the sampling of fish with electricity that facilitates sampling and analysis of fish to draw conclusions related to aspects such as reaction to changes in the environment.
BS EN 14011 sampling procedures with electricity procedures to be used by trained persons in evaluating fish communities in streams, rivers and littoral areas for the purpose of classification of ecological status.
BS EN 14011 procedures allow standardisation of sampling methods for descriptions of fish communities. The use of standardised methods is a critical requirement for the comparability of results.
BS EN 14011 describes an electric fishing method to be used when catching fish for the purpose of characterising the composition, abundance and age structure of a given fish community. Sampling-related issues include obtaining permissions, concerns about endangered species, protective measures of importance for the user of the sampling apparatus and coordination of activities with other sampling programmes.
In BS EN 14011, the processing of samples covers taxonomic identification, counting, measurement of biologic parameters (length, weight etc.), and examination of fish for external anomalies.
BS EN 14011 on the sampling of fish with electricity applies to:
Fish sampling is a common method of gathering information about fish populations, classification of ecological status and ageing analysis. The quality of sampling data is influenced by the design of the sampling programme, the accuracy and precision of measurements and the reliability of the system used to manage it.
BS EN 14011 provides users guidance on equipment, including lifejackets, nets, fish containers, communication equipment, and more, ensuring safety and protection in the sampling of fish with electricity.
BS EN 14011 provides users guidance on scope, normative reference, principle, equipment, safety aspects, fishing procedures, identification and measurements of fish, release of catch, results, quality assurance, quality control and report, enabling users to accurately sample fish with electricity for further analysis and investigation.
With obedience and compliance to BS EN 14011, users can sample fish with electricity for identification, measurement, size and age structure for purpose of ecological status and research and analysis of the fish in different environments.
