Popis: |
We describe habitat needs for fish populations in estuaries needed to ensure the realisation of ecological goals. We take the view that Good Ecological Status (GES), as defined by the European Union Water Framework Directive (2000/60/EEC), is obtained when those ecological goals are fulfilled. The Zeeschelde estuary is presented as a case study for the description of ecological goals, but the described approach can be applied to all North Sea estuaries. In order to make the method widely applicable we first classify fishes into guilds, relevant for the formulation of ecological goals. Next we describe guild-specific ecological goals for fish. Based on the literature, habitat requirements for specific fishes are defined and used to define habitat needs allowing a proper functioning of the estuarine ecosystem. We describe habitat needs at a guild level and indicate how these can be achieved. |
