Epidemiological study of Acanthogyrus tilapiae, gut parasitic helminth of Hemichromis elongatus in the Mefou hydrographic system (South-Cameroon): Effect of the environment

Abstract: Hemichromis elongatus is used as a voracious accompaniment to control Tilapia in fish farming. The management of parasitic problems is a major limiting factor of aquaculture. This study compares the dynamics of Acanthogyrus tilapiae infections in H. elongatus in three different ecosystems of the Mefou hydrographic system. Fish were sampled from December 2017 to September 2019. From the 303 host specimens examined, a total of 1034 A. tilapiae individuals were collected. The high infection observed in the forest downstream course (prevalence= 89.7% and mean intensity=13.55 ±1.66) is probably due to the abundance of intermediate hosts in the wild. In the Mefou dam, the lowest epidemiological values (prevalence = 0.8% and mean intensity = 1±0) could be linked to the low abundance of invertebrate hosts. These findings reinforce the practice recommending quarantining native fish specimens captured in the wild and used as sires in ponds, in order to avoid epizootic outbreaks.
