摘要：

The standard metabolic rates (SMRs) of 11 (1.395-4.125 kg) dolphin fish (mahimahi or dorado, Coryphaena hippurus) were measured at 25 degrees +/- 0.5 degrees C. Fish were prevented from swimming with neuromuscular blocking agents and force ventilated. Heart rates were determined simultaneously. SMRs (358-726 mg O-2 h(-1)) were several times those of other similarly sized active teleosts such as salmonids, but close to those of tunas. Heart rates (84-161 beats min (-1) ) were also high, but alike those of tunas under similar circumstances. As in tunas, the high SMR of dolphin fish may result from high osmoregulatory costs engendered by their large gill surface areas and/or other adaptations necessary for achieving exceptionally high maximum metabolic rates.
