Sea water dilution (to 5% and 1% of sea water) induced a reversible, plasma metabolic acidosis in a euryhaline teleost (the oyster toadfish, Opsanus tau ). Net H+ transfer between the fish and the water decreased in both low salinity exposure (LSE) groups during the first week of exposure and ΔH + returned to normal after ∼10 days of 5% LSE, but not during 1% LSE.
