This paper reports detection of coccidia oocyst from twenty five Clarias gariepinus raised in plastic tanks in Sabon Gari, LGA in Kaduna State. Using simple floatation technique, oocysts were recovered from the intestinal content and gills of Clarias gariepinus. Oocyst number varied from 9 -15 oocysts per slide viewed at x 10 optical magnification of the microscope with the intestines having the highest occurrence. The fish were anorexic and lethargic and post-mortem examination of the dissected fish revealed little or no abdominal fat, pale gills and haemorrhages in the gastrointestinal tract. Forty- eight percent of the examined fish were positive for oocyst. The oocyst was detected more in fish specimen weighing between 240g-300g (58.3%) and length ranging from 28.3cm-30.3cm (66. 7%). The Fulton's condition factor of the infected fish was lower than the uninfected fish. The findings indicate that intestinal Coccidiosis may pose significant health problems in fish; management practices and biosecurity protocols need to be improved.
