O2 tension, swimming-velocity, and thermal effects on the metabolic rate of the Pacific albacore Thunnus alalunga.


The oxygen consumption rates (VO2) of 9 albacore tuna, Thunnus alalunga (8.5-12 kg) were measured at sea in a swimming respirometer to determine the effects of relative swimming velocity, ambient O2 tension, and water temperature. Significant positive relationships were obtained between tail-beat frequency and relative speed and between relative speed and… (More)
