An in situ mesocosm experiment was designed to investigate how exposure to ocean acidification by increased carbon dioxide affected the growth of juvenile oliver flounder (Paralichthys olivaceus). A total of 447 individuals were reared in the mesocosm experimental devices deployed at sandy-muddy bottom in the southern coast of East Sea for 43 days and divided into two groups: treatment group (223 individuals, 6.32±0.75 cm, high-CO₂ environment) and control group (224 individuals, 6.34±0.84 cm, natural CO₂ environment). The average values of pH and CO₂ concentration in the treatment device were 7.63±0.13 and 1660±540 μatm, respectively, while those in the control device were 8.07±0.05 and 514±65 μatm, respectively. There was no significant difference in mortality rate between treatment and control group, and the mortalities in two groups gradually decreased during the study period. But, the increase of size and weight of juvenile oliver flounder was higher in control group than treatment group, i.e., weight gain or growth rate was higher in control group. These results suggested that high CO₂ environments could have a significant negative influence on the early growth of juvenile oliver flounder.
