Temperature and pressure dependency of oxygen consumption during long-term sustained swimming of European eels
Many aspects of the typically 5000–10,000 km spawning migration of the European eel (Anguilla anguilla) remain unknown. As part of this migration, eels undertake extensive diurnal vertical migrations to depths below 1000 m, being exposed to a wide range of temperatures and hydrostatic pressures. In...
