A model of total swimming costs in turbulent flow for juvenile Atlantic salmon ( Salmo salar)
Juvenile Atlantic salmon (Salmo salar) live in rivers characterized by highly turbulent flows. In these environments, flow turbulence is associated with a wide range of instantaneous flow velocities, which may affect the energetic costs of habitat utilization of juvenile Atlantic salmon. The purpose...
