The objective of this study was to evaluate the effects of acute hypoxia on the physiological stress responses (plasma cortisol as the primary response, and hematocrit, hemoglobin, plasma glucose, sodium, chloride, osmolality, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) as the secondary responses) of Korean rockfish. The mortality in Korean rockfish started at 0.7 mg L-1 and 0.8 mg L-1 levels at 12℃ and 20℃, respectively. And the time required for the mortality in experimental fish was 274 and 148 minutes at 12℃ and 20℃, respectively. Levels of hematocrit, hemoglobin, AST, ALT, ion concentration, osmolality, glucose and cortisol had significantly increased with decreasing dissolved oxygen at 12℃ and 20℃.
