“…However, it should be noted, that the status of some fish species might vary geographically. For instance, a particular species may be abundant in one region, but threatened in another; this is because some rare fishes are at the limits of their geographic distribution (Seegert, 2000;Costello et al, 2002). It should be noted that changes in the distribution range and abundance of certain species could also be a result of global factors such as climate change rather than local conditions.…”

There is an increasing need in assessing ecological quality and integrity of estuaries and lagoons. This chapter shows the most recent efforts in assessing individual biological elements (from phytoplankton to fishes), together with the integrative tools developed in different geographical areas worldwide. However, reducing complex information from multiple ecosystem elements to a single color or value is a substantial challenge to marine scientists, and requires the integration of different disciplines (chemists, engineers, biologists, ecologists, physics, managers, etc.), to reach agreement on the final assignment of ecological status. Hence, in the near future, emphasis needs to be directed at understanding the complexities of estuarine system functioning rather than simplifying and scaling down the system into smaller components.

“…This does not mean, however, that a B-IBI index cannot be developed for those systems, but each application must be specifically developed for the system in question; thus re-parameterizing the reference measures used for comparison and scoring attribution for each estuary. This has been already stated for freshwater environments (Seegert, 2000), where it is considered that even between identical ecoregions or faunas some fine metrics and/or scoring tuning have to be done.…”

“…Moreover, following Seegert (2000) the IBI metrics or metric scoring criteria transferability from one watershed to another should not be done without the respective recalibration. According to Costanza (1996) two estuarine assemblages with different taxa may be functionally similar due to the high inherent functional diversity.…”

“…In all methods however, reference sites play a major role (Adriaenssens et al, 2002a). Metric thresholds should not be based on expert judgement rather on the evaluation of the zone-specific data (Seegert, 2000). Minimally disturbed sites are sometimes used as a reference to select optimal metric scores and score classes are determined by dividing the total metric range in three or five equal portions (assuming a linear behaviour of the metrics) (Deegan et al, 1997;Hughes et al, 2002;Harrison and Whitfield, 2004;Breine et al, 2007;Coates et al, 2007).…”

Keywords:Biotic integrity Fish-based index Meso-and oligohaline estuary Freshwater European Water Framework Directive Zeeschelde a b s t r a c t Fish-based indices monitor changes in surface waters and are a valuable aid in communication by summarising complex information about the environment (Harrison and Whitfield, 2004). A zone-specific fish-based multimetric estuarine index of biotic integrity (Z-EBI) was developed based on a 13 year time series of fish surveys from the Zeeschelde estuary (Belgium). Sites were pre-classified using indicators of anthropogenic impact. Metrics showing a monotone response with pressure classes were selected for further analysis. Thresholds for the good ecological potential (GEP) were defined from references. A modified trisection was applied for the other thresholds. The Z-EBI is defined by the average of the metric scores calculated over a one year period and translated into an ecological quality ratio (EQR). The indices integrate structural and functional qualities of the estuarine fish communities. The Z-EBI performances were successfully validated for habitat degradation in the various habitat zones.
