A cross-sectional study was conducted from April to October 2023 along the downstream of River Nkam in Yabassi locality (Littoral-Cameroon). The objective was to determine parasite fauna, the prevalence, abundance, mean intensity and risk factors of parasitic infections in wild freshwater fishes as for their control during their successful domestication and conservation. A total of 151 fishes comprising 43 Ctenopoma petherici, 31 Clarias jaensis, 21 Parachanna obscura, 25 Chrysichthys nigrodigitatus and 31 Oreochromis niloticus randomly captured from the River Nkam were used for the determination of the parasitological indexes. The results showed an overall high prevalence of multiple infections of 72.85% of all the fish species by five groups of parasites (p<0.0001) namely monogeneans (61.53%), trematodes (18.54%), myxosporeans (19.90%), cestodes (2.83%) and nematodes (8.72%). Besides, the abundance and mean intensity of monogeneans infection were either low or average and not influenced by the fish species. The significance of the effect of the fish sex, size and weight on the infection by monogeneans depended on fish species. Fishes from the Nkam river should be quarantined and treated against parasites before farming.

A test was carried between January and June 2014 in the zone of Nkolnkondi II, district of Yaounde 5th, area of Center Cameroon with and aim of contributing to the performance evaluation of growth of Clarias jaensis in fertilized ponds. A total of 4000 fingerlings of Clarias jaensis of average weight (20,39

The effect of stocking density on the growth performance of Clarias jaensis in pond was studied in the zone of Nkolnkondi II, area of center Cameroon with an aim of contributing to the improvement of the production by the optimization of the stocking densities. A total of 1000 fingerlings of Clarias jaensis of average weight (20,39
