Abstract
Routine metabolism of the euryhaline cyprinodontid Cyprinodon variegatus Lacepede was measured at a series of ambient salinities ranging from fresh water through 100‰. Fish used had been sequentially acclimated to the test salinities (ambient temperature of 20±1° C and a 12: 12 L: D schedule).
Routine metabolic rates were highest at ambient salinities from 15 to 50‰. Metabolism was somewhat lower at ambient salinities less than 15‰, and showed a sequential decline at ambient salinities greater than 50‰. It is suggested that routine metabolism is depressed at elevated salinities by reduced O, transfer, a consequence of maintenance of hydromineral balance in hypersaline waters.
