Abstract: Pollution status of water and parasite load of Clarias gariepinus in Digil Dam, Mubi, Adamawa State was conducted from October to December, 2019. Water samples were collected from three sites of the Dam for physico-chemical analysis, and some of the parameters were measured on site. Water temperature fluctuated between 23.90oC to 24.70oC which was moderate for supporting aquatic life. Dissolved oxygen was lowest at site A and highest at site C in the month of October. Conductivity of the water body ranged between 12.60 µS/cm at site B in the month of October and 15.00 ± 0.00a µS/cm at site C in the month of December, turbidity ranged from 3.65 at site A to 43.00 cm at site B in the month of October. pH was near the normal range for aquatic organisms. The concentrations of heavy metals ranged during the period of the research were Copper (0.062 to 0.086 mg/L), Zinc (0.011 to 0.016 mg/L), Lead (0.00 to 0.114 mg/L), Cadmium (0.00 mg/L) and Iron (0.00 to 2.14 mg/L). The result of this study also revealed that different parasites belonging to different parasitic groups are protozoa (Trichodina sp, Coccidia sp, Chilodonella sp, Ichthophthirius sp, and Ichthyoboda sp.), one species of Leech (Pisciolo gemetra sp,) respectively were observed to be present in C. gariepinus used for this research work and at both sites samples. The result revealed that Clarias gariepinus are infected with ectoparasites. Therefore, it was recommended that prevention of water contamination by raising public awareness of the dangers of misuse water bodies and avoiding eating half cooked freshwater fish and cooking fish enough will prevent infection with the fish parasite.
