Abstract
The main aim of the Egyptian government is not only to increase the fish production from the different resources, particularly from aquaculture, but also to improve the quality of the produced fish. For this purpose, the contaminant heavy metals in Oreochromis niloticus produced from El-Max fish farm were investigated. Fish samples were taken randomly from four basins in July and September to measure heavy metals load on (fish muscle and liver), as well as, condition factor. Positive significant correlations with body weight were found for Zn concentration. The results obtained show that the concentrations of all measured heavy metals, especially Fe and Cu, in muscles of fishes collected from El-Max fish farm exceed the global maximum limits. The hazard index is below 1, but in the future human risk may occur depending on the agricultural and industrial development in this region.
Key words: Heavy Metals, Tilapia, El- Max Fish Farm, Risk Assessment.
