Sea bream (Sparus aurata) acclimated to 1.3% and 0.3% salinity for one week did not show significant changes in haematology except for the number of red blood cells, which decreased at the lowest salinity. Both ventilatory frequency and oxygen consumption increased significantly in the 0.3% salinity group and plasma osmolality significantly decreased in the same group. Since no mortality was recorded, these results suggest that sea bream is able to acclimate to low salinities although this acclimation involves a higher metabolic cost. Results are discussed in connection with other works dealing with low-salinity acclimation and the adaptability of euryhaline fishes. © 1994.
