WFD Cycle 2 TraC Fish Classification
This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for fish in transitional waterbodies. Fish are caught using a variety of techniques throughout each waterbody classified and the data is pooled over the most recent six year period. The pooled datasets can be used to indicate the ecological status of a transitional waterbody. There are ten metrics on various facets of composition and abundance designed to explore different components of species diversity in order to determine the health and quality of a transitional waterbody. The actual (observed) scores for these metrics are compared with a reference score derived from data collected in a similar way between 2006 and 2011. The comparison of the observed to expected scores is known as an Ecological Quality Ratio (EQR). EQRs are used to produce a classification (High, Good, Moderate, Poor, Bad) of the water body for Water Framework Directive (WFD) purposes.

The Water Framework Directive classification system is risk based and focuses on where there is likely to be a problem. It uses a principle known as "one out, all out", which means the poorest individual results drive the overall classification for a water body. It reports on over 30 quality elements, grouped into ecological status and chemical status. Ecological status includes physico-chem (e.g. nutrients, pH, dissolved oxygen, ammonia) , biological elements (e.g. phytoplankton, macroalgae, fish, invertebrates) , specific pollutants (e.g. metals and compounds, organic compounds) , hydromorphology (e.g. depth, width, flow, structure). Chemical status is assessed using priority substances, priority hazardous substances and other pollutants that present a significant risk to the water environment.
