| Two different groups (30 and 60 inds.) of olive flounder (Paralichthys olivaceus) were abruptly (within 30 min) exposed to hypo-salinities from seawater (SW, 35$ extperthousand$) to freshwater (FW, 0$ extperthousand$) (30FW and 60FW) and to 35$ extperthousand$ (30SW and 60SW) in a flow through seawater culture systems. Analysis of plasma samples showed the following significant increase at 0$ extperthousand$: cortisol from $2.8;ng;mL^{-1}$ to $66.9;ng;mL^{-1}$ (30FW) and from $2.7;ng;mL^{-1}$ to $314.1;ng;mL^{-1}$ (60FW) after 24 hours of exposure; glucose from $15.8;mg;dL^{-1}$ to $257.7;mg;dL^{-1}$ after 3 hours exposure and to $164.0;mg;dL^{-1}$ after 24 hours in 60FW. Plasma $Na^+$ concentration of 30FW and 60FW were decreased until 24 hours after expose. However that in 30SW and 60SW showed no significant differences. Plasma $Cl^-$ concentration of 60FW was decreased from $59.0;mEq;L^{-1}$ to $43.5;mEq;L^{-1}$ and to $30.0;mEq;L^{-1}$ after 3 and 24 hours of exposure, respectively. At all experimental groups, survival were 100% until 24 hours. |
