The incidence and intensity of nematode infection was investigated in Nile tilapia Oreochromis niloticus from Lake Kyoga, Uganda and 11% of the 406 fish examined were parasitized by nematodes of the genus Contracaecum. The prevalence of these parasites was greatest in the smallest and largest size classes, but this may reflect their small sample sizes. The prevalence of Contracaecum was similar to that in tilapias from a reservoir in India but much lower than in fish from South Africa and Ethiopia.
