Description
Summary:tA simple procedure to harmonise and intercalibrate eight national methods classifying the ecologicalstatus using fish in transitional waters of the North East Atlantic is described. These methods were initiallyintercalibrated and a new method recently developed was added to this exercise. A common humanpressure index pre-classified the status of each water body in an independent way. Ecological classboundaries values were established according to the level of anthropogenic pressure using regressionanalyses. A simulated dataset was used to assess the level of agreement between the fish classificationmethods. Fleiss' multi-rater kappa analysis indicated that boundary harmonisation was achieved; allclassifications fell within one class of each other and class agreement between methods exceeded 70%.The use of a pressure index to establish boundary thresholds provides a practical method of defining andharmonizing the quality classes associated with human pressures, as required by the European WaterFramework Directive.
