Abstract
Experiments were carried out to investigate the effects of lead exposure on survival, growth and oxygen consumption of juvenile oliver flounder, Paralichthys olivaceus. Survival rate of the oliver flounder was significantly affected above 150㎍/L. Growth of the olive flounder exposed to ≥ 150 ㎍/L of lead concentration was significantly lower than that of fish reared in normal condition. Metabolic rate of fish exposed to lead ≥ 80 ㎍/L concentration was significantly reduced with increasing lead concentration than that in normal condition. This study revealed that high lead concentration (≥ 80 ㎍/L) reduced growth and metabolic rates of juvenile olive flounder suggesting potential influence of lead on the natural mortality of olive flounder in the coastal areas.
