| Summary: | Abstract The purpose of this study is to investigate the changes in growth, hematological parameters, and plasma components of juvenile starry flounder, Platichthys stellatus, following exposure to varying arsenic concentrations present at different water temperatures. P. stellatus (total length, 15.9 ± 0.4 cm; body weight, 62.2 ± 4.2 g) were exposed for 4 weeks to waterborne arsenic (sodium arsenite, As) at 0, 150, 300, and 600 μg/L at temperatures of 12 °C and 18 °C. Toxic effects of As exposure on P. stellatus were higher at the higher temperature and the growth and hematological parameters measured decreased with increasing arsenic concentration, while the concentration of plasma components measured increased. This indicates that waterborne As exposure and water temperature can cause toxic effects on growth, hematological parameters, and plasma components in Platichthys stellatus.
