7 pages, 5 figures Swimming activity of turbot was recorded in a 250 m2 earthen pond by acoustic tracking and was analysed in relation to illumination, temperature and oxygen concentration. A pronounced diurnal rhythm was found, with greater activity at night. Illumination interacted with both temperature and dissolved oxygen concentration in determining swimming activity. Activity increased with temperature, particularly above 20 °C at night, without a clear effect of oxygen concentration level ranging between 4 and 9 mg l−1 Peer reviewed
