The current study aimed to afford baseline information on the level of twenty one organochlorine pesticides (OCPs) and four heavy metals in muscles of Oreochromis niloticus and Mugil cephallus. This will help elucidating the present status as chemical contaminants in the fish species. A total number of thirty fish from each species were collected to set up this study. Nile tilapia (Oreochromis.niloticus), was noticed to contain higher levels of most estimated types of Σ HCH in (40% of Tilapia) and Σ CHLRs. While Mullet (Mugil cephallus) was higher only in DDTs. Meanwhile, Σ HCB, Σ DRINs and Σ HPTs were the lowest. The recorded results demonstrated that organochlorines were within the permissible limit according to FAO except for the CHLRs, it exceeds the permissible limit in 100% (N=30) of tested samples of Nile tilapia for all isomer. The analytical data obtained from such study declared that the level of Cd, Zn and Cu were significantly (p≤ 0.05) higher in Mullet than Tilapia but vice versa for Pb. It was evident, that all the detected metals were within the permissible limits according to FAO and WHO. Except for Zn, It exceeded the permissible limits in 50% of the analyzed samples in Mullet.
