Osmoregulatory Plasticity of Juvenile Greater Amberjack () to Environmental Salinity.

Osmotic costs in teleosts are highly variable, reaching up to 50% of energy expenditure in some. In several species, environmental salinities close to the isosmotic point (~15 psu) minimize energy demand for osmoregulation while enhancing growth. The present study aimed to characterize the physiological status related to osmoregulation in early juveniles of the greater amberjack, acclimated to three salinities (15, 22, and 36 psu).
