Swimming physiology and metabolic costs of swimming are important for understanding the effects of environmental factors on fish behavior. The new hyperbaric swimming respirometer (HSR) is a valuable tool for studying fish physiology during swimming, as it can simulate depths of up to 80m. The HSR has been successfully tested with female European eels (Anguilla anguilla) and provides opportunities for future research on the effects of pressure, temperature, and flow velocity on fish metabolism and swimming performance.
