Abstract: The present work aimed to estimate the toxicity of cadmium and copper to fingerlings of marine fish Mugil seheli, as well as the effect of different concentratios of Cd and Cu on some biochemical parameters (Aspartate and alanine transaminase enzymes, glucose, glycogen, lipid and protein) in the fish organs. 96-h LC50s of Cd and Cu were 5.36 and 1.64 ppm, respectively. Levels of aspartate and alanine transaminase were reduced within 2 days of exposure to different concentrations of Cd (2.0 and 0.5 ppm) and Cu (0.5 and 0.2 ppm) in both plasma and muscle tissue. Glucose was increased reaching the highest values after 4 days of the treatment with Cd and Cu, while muscle glycogen was increased at first days then dropped after 14 days below control level. Generally, total lipids and proteins in plasma and muscle recorded higher values than the control one.The present study showed high toxicity of copper to fish Mugil seheli comparing to cadmium.
