| We examined the effect of salinity on hematological changes and survival in the cultured olive flounder, Paralichthys olivaceus. Fish (mean length: 20.8 cm, mean weight: 96.1 g) were abruptly (within 30 min) exposed to salinities from 15 to 0 psu (Group I, G I) and to 35 psu (Group II, G II). After maintain during days 5, the fish were again changed from 0 to 35 psu (G I) and from 35 to 0 psu. We measured cortisol, glucose, $Na^+$, $Cl^-$, $K^+$, aspartate amino-transferase (AST), and alanine amino-transferase (ALT), hematocrit, RBC, hemoglobin and survival during the 10-days test period. Our results in G I showed that olive flounder exhibit "typical" physiological responses (in cortisol, glucose, $Na^+$, $Cl^-$, AST and survival) to the stress induced by salinity changes. In G II, olive flounder were significantly different in cortisol, glucose, and AST at 240 hours. The survival in two groups were reduced in 0 psu than 35 psu during the experimental period. This research provides baseline data on cortisol, glucose, $Na^+$, $K^+$, $Cl^-$ and survival for hypo or hyper-salinity changes. |
