The study of length-weight relationship and condition factor of Mormyrus rume in Kainji Lake and River Rima water bodies was carried out from January to December 2018. Five hundred and thirty-one (531) samples from Kainji Lake and four hundred and seventy-seven (477) samples from River Rima (making a total of 1,008 samples), were collected from fish landing sites of the water bodies and subjected to standard methods of analysis. The length and weight of M. rume from the two water bodies were measured to obtain the growth rate of the fish. The standard length (SL) of the fish was measured from the tip of the anterior part of the mouth to the end of caudal fin using measuring board. Fish were measured to the nearest centimeter The result of the study showed that M. rume had negative allometric growth pattern from both water bodies with a growth exponent (b) value of 1.7966 and 2.2108 respectively. The mean condition factor (K) for M. rume in Lake (1.99) and River (1.02), showed that the fish is in good condition. There were variations in monthly condition (K) of the fish, which were still favourable for the survival of M. rume in both water bodies even though more favourable in lake.
