Abstract
Several physiological variables related to salinity acclimation in Liza abu were
examined, using oxygen consumption rate and glucose level as an indication of
osmoregulatory energetic. l~'reshwater acclimated I.. aim were transferred to two salinity (7
and 15 g/L) oxygen consumption rates. glucose levels and plasma ion concentrations (Na i.
K’) were measured after three days of transfer to higher salinity. Plasma ion concentrations
were elevated after transfer. Blood glucose level increased after transfer to salinity 7 g/L
while its level decreased in salinity 15 g/L compared to its level in freshwater. Oxygen
consumption rate increased one and half time of that in freshwater but no significant
difference were noticed in oxygen consumption rates between fish in both salinities (7 and
15 g/L) .'l'he amount of metabolic energy consumed during salinity acclimation were also
determined. The result showed that the physiological changes associated with salinity
acclimation impose a significant short - term energetic cost.
