| In order to estimate chornic toxicity of copper in the juvenile oliver flounder, Paralichthys olivaceus, experiments were investigated the effects of long term sublethal copper exposure on survival rate, metabolic rate, feed efficiency and growth rate. Oliver flounder were exposed for 6 weeks to four different sublethal copper concentration (50, 80, 180, 320 $mu extrm{g}$ $L^{-1}$). Survival rate of them significantly affected above 180 $mu extrm{g}$ $L^{-1}$, and reduced for increase exposure periods and concentrations. Copper exposure to 180 and 320 $mu extrm{g}$ $L^{-1}$ significantly decreased metabolic rate in olive flounder. Exposure to waterborne copper concentrations as high as 80 $mu extrm{g}$ $L^{-1}$ resulted in significantly reduced feed efficiency and growth rate. From these results, it could be concluded that the high level of 80 $mu extrm{g}$ $L^{-1}$ copper concentration in the bottom water would curtail production of the olive flounder in coastal area. |
