This study investigated the effect of increasing dissolved oxygen concentration using oxygen dissolver and liquefied oxygen on survival rate and physiological changes to reduce mortality of black rockfish (Sebastes schlegelii) in high water temperature periods. The experiment divided into 4 groups (A, control group (water temperature 23-24℃, no device install); B, combination of liquefied oxygen and oxygen dissolver; C, liquefied oxygen; D, without device install). The water temperature was raised by 0.5℃ per day and maintained for a week after reaching 30℃. The dissolved oxygen concentration was significantly higher in group B compared to another groups. In survival rate, in group D, death occurred when the water temperature reached 30℃, and the entire populations died within 7 days. The survival rate of the group B and C was 100%. As a result of blood analysis, osmolality and magnesium showed significant differences only in group D. Glucose and cortisol, which are used as stress indicators, were measured significantly lower in group B and C. GPT and GOT were measured to be significantly higher only in group D. Therefore, it is believed that the use of oxygen dissolvers and liquefied oxygen will be effective in reducing the mass mortality of marine net cage in high water temperature periods by increasing the amount of dissolved.
