Abstract

This study was conducted to examine the hematological factors in cultured olive flounder Paralichthys olivaceus depending on its growth stage and season. The study also aims at developing the standard hematological indicator for growth stage and season by examining total 16 parameters including whole blood (hematocrit, red blood cell and hemoglobin), biochemical (glucose, cholesterol, total protein, AST, ALT, Na?, K?, Cl?, Ca²?, Mg²? and osmolarity), and endocrine (cortisol and T₃) factors in plasma of cultured olive flounder. The result showed a growth stage-dependent increase of T₃ level in olive flounder while the level of cholesterol showed an inverse correlation to fish size. For seasonal fluctuation in cultured olive flounder of the same growth stage, the highest level of Ht and RBC was observed in autumn.
