Modelling fish movement trajectories in rivers.

Abstract: We present an integrated model that consists of a hydrodynamic model and a Fish Movement Model. Firstly, we calibrate the model using measured water velocities and fish trajectories in a part of the Konge River in western Denmark that is confined by 3 river sections: (1) inflow-upstream, (2) outflow towards a fish farm, and (3) outflow-downstream. Secondly, we perform a sensitivity analysis to identify the most significant model parameters. Thirdly, we apply the model to simulate fish trajectories; calculated fish numbers (1) exiting from the two outflows and (2) showing milling or not behaviour, are in satisfactory agreement with measured values.     «
