Abstract: The present survey on population’s dynamics of gill monogeneans aimed to contribute in minimizing catastrophic losses in potential fish ponds. Monogeneans were dislodged from the gill filaments, with the aid of a dissecting needle and mounted between slide and cover slip in a drop of water. They were identified and counted using a microscope. The present study revealed three monogenean species gill parasites of Synodontis rebeli: Synodontella melanoptera, Synodontella sanagaensis and Synodontella sp. These parasite species are aggregated among the host population.
