Intercalibration of fish-based methods to evaluate river ecological quality, Report from an EU intercalibration pilot exercise
To become functional tools in the implementation of the water framework directive, national methods must be intercalibrated. This task has not yet been carried out for the ecological quality element FISH. As national monitoring networks has been established and different methods developed during the last years, a first attempt to compare and intercalibrate the quality boundaries set by the different methods has been done. This report is mainly based on results and descriptions submitted from each of 7 IC-groups. We have tried to draw some main conclusions and recommendations based on the work done by all the people involved and also some editing of the reports and other documents to make the information more accessible and clearer for the reader, however the contend is unaltered and expresses the experience and views from the groups. Each group report is placed as an annex. To limit the variation, these group reports are organised in a similar way, first answering a set of questions, then describing in more detail the process and the results, then descriptions of the national methods used and finally the criteria used for setting reference conditions. Since the first meeting in May 2006, much effort has been put into this pilot exercise by a number of people from more than 20 Member States. We have been working with 3 categories: 1) MS with an accepted/approved national method, 2) MS with methods under development/approval and 3) MS without any national method (planning to use common metrics or other countries methods). The results of the comparisons between different regions and methods demonstrate that more work is needed before intercalibration with boundary setting can be achieved. Especially the lack of common criteria for reference conditions is an obstacle in the progress of this work, so a future workplan is proposed.
