Respiration of Benthopelagic Fishes: In situ Measurements at 1230 Meters

Abstract

The respiration rate in situ of two common benthopelagic fishes, Coryphaenoides acrolepis and Eptatretus deani, was monitored at 1230 meters in the San Diego Trough. The respiration rate of C. acrolepis was two orders of magnitude lower and that of E. deani was significantly lower (P < .05) than rates in comparable shallow-water species.
