We are conducting research into the environmental tolerances of salmon and cleaner fish. In particular we are looking into swimming capability under different conditions, and how strong water currents affect behaviour and physiology. For this purpose, we have developed and established a new methodology and new protocols (push cages and swimming tunnels).
