    Indiscriminate discharge of home, agricultural, and industrial wastes into water bodies, most rivers and reservoirs around the world are becoming polluted. The ecotoxicological potential of this in sh species gathered from important reservoirs and rivers in Ilorin, Nigeria, was explored in this study. Unilorin reservoir, Asa reservoir, Apodu reservoir, Asa river (Unity), and Asa river (Unity) water samples were collected and physicochemical characteristics were investigated at ve distinct sites: Unilorin reservoir, Asa reservoir, Apodu reservoir, Asa river (Unity), and Asa river (Unity) (Harmony). In Tilapia zillii and Clarias gariepinus, we measured serum biochemical (AST, ALT, ALP, serum ALB), histopathological (gills, lungs), and serum antioxidant enzyme responses (SOD, CAT, GPx, GR, GST) as a biomarker for oxidative stress, while micronucleus and comet assays were used to detect DNA damage. Except for DO, which was very low in the two rivers, the physicochemical parameters and heavy metals evaluated in the ve separate water bodies were within the allowed levels of the NSDWQ and WHO standard for drinking water. In comparison to the Unilorin, Apodu, and Asa reservoirs, a slight increase in Pb was observed across the ve sampling sites, which could contribute to increased biochemical and haematological pro les, histopathological lesions in the gill and lungs, inductions of MN, NA, and DNA single strand break in T. zillii and C. gariepinus collected from Asa rivers. This could be due to the indiscriminate dumping of e uents from adjacent industries, agricultural wastes, and household wastes into rivers.
