In this study concentration of heavy metals; Cadmium, Lead, Zinc and Ferrous (Cd, Pb, Zn and Fe) were studied in tissues (muscles, gills, gonads and liver) of cultured carp fish (Cyprinus carpio L.) of the earthen ponds belonged to Basra University. Two stations were selected, the first was for the ponds of Marine Sciences Center and the second one was for the ponds located in the Al-Hartha Station for Agricultural Research. The results showed that the iron element recorded the highest concentrations in all the studied tissues in rang (8.22-53.81 mg/kg), while the cadmium element showed very slight detected. The liver organ showed the highest levels of cadmium and lead (0.0047 and 0.186 mg/kg) respectively, while the gill organ showed the highest level for zinc and iron (5.73 and 53.81 mg/kg). All concentrations of the elements were within the permissible level.
