The aim of the present study is to provide an overview about the impact of feeding fish on chicken manure (CM) or fermented chicken manure (FCM) on the physico chemical character of water and performance of fish, as well as public health hazards and risks associated with consuming such fish in regard to fish quality. Nile tilapia (Orechromis niloticus) as an experimental fish where stocked into 7 groups (G) with duplicate treatment. Each group received different mixture of CM or FCM with fish ration (FR), 0:100, 25:75, 50:50 and 100:0 (% CM or FCM: % FR). Physico- chemical character of water and heavy metal load (Cu, Pb and Zn) of water and fish, as well as fish performance were measured and compared with control group received only fish ration (FR). Total volatile base nitrogen (TVB-N) was also used for determining fish quality. Unionized ammonia (UIA) was significantly high (P< 0.05) at groups received FCM resulted in 100% mortality in such groups. TVB-N values were significantly (P
