Incidence of Lernaea cyprinacea on Lake Malawi Kampango (Bagrus meridionalis)


Author(s): Mwamad Salim M’balaka

Abstract: The incidence of Lernaea cyprinacea on Lake Malawi Kampango Bagrus meridionalis was assessed. B. meridionalis specimens primarily from a research vessel called Ndunduma based at Monkey Bay Fisheries Research Station were used during the study. The study revealed that prevalence was distributed throughout the year with some peaks during cold and rainy season. A significant difference (P<0.05) on the preferred places of attack on the fish were noted during the study and the most common part of the fish to find L. cyprinacea were in the gills which contributed 77%, followed by an area around pectoral fin (13%) then around ventral fin (10%) and finally other places with negligible contribution. More than half (53%) of the sampled fish population were infected. Prevalence level was noted to increase with an increase in size of the host. There was no any significant effect (P<0.001) of the attacks on the B. meridionalis’s health as there was a strong correlation between length and weight of the infected fish. The study has reported the incidence of the L. cyprinacea on Lake Malawi B. meridionalis hence, a great need for further studies on various parameters associated with the infested B. meridionalis.
