What is BS EN 17233 about?
BS EN 17233 on water quality specifies standardized methods for assessing the efficiency and related metrics of fish passage solutions using telemetry techniques that allow individual fish approaching an impediment to be monitored.
Note 1: BS EN 17233 covers studies using fish that have been electronically tagged with acoustic, passive integrated transponder or radio tags to provide a variety of defined passage efficiency metrics and includes both upstream and downstream passage of fish.
Note 2: BS EN 17233 provides recommendations and requirements for equipment, study design, data analysis and reporting.
Who is BS EN 17233 for?
BS EN 17233 on telemetry for fish passage solutions is used by:
- Government authorities
- Marine biologists
- Hydrologists
- Marine conservationists
Why should you use BS EN 17233?
Fish passage solutions are measures to help fish pass a cross-river obstacle or impediment in upstream and/or downstream directions.
Impediments to fish migration and associated fish passage solutions occur in freshwater and transitional water bodies within a wide range of habitat types. The telemetry techniques covered by BS EN 17233 enable monitoring in all of these, although no single method can be used across the whole range of water body types.
BS EN 17233 helps you in assessing the efficiency and related metrics of fish passage solutions. BS EN 17233 deals exclusively with telemetry for fish passage solutions as an agreed method for the judgment of the efficiency (attraction efficiency, entrance efficiency, passage efficiency, and overall fish passage solutions efficiency) to achieve highly standardized and comparable results for selected species and age classes.
BS EN 17233 helps you to determine the appropriateness of the chosen design of a fish passage solution by providing data about the effectiveness and/or the efficiency for fish that must cross the impediment. A well-functioning solution can serve as an example of a solution in a similar river type with a similar fish community.
