Fish trajectories over a full-scale model of a nature-like unstructured block ramp

Sammanfattning

Preliminary results of ethohydraulic tests with brown trout on a full-scale partial model of an existing nature-like unstructured block ramp are presented. The tests are part of the "MigRamp" project that aims to identify and quantify the migration corridors for upstream migrating fish by linking fish trajectories with bed topography and local flow field under laboratory and field conditions. The results from laboratory experiments show that observed migration paths depend on the combined effect of flow conditions and bed geometry in the way that migrating fish avoided the main flow channel with increasing discharge.
