Abstract
This study examined the length weight relationship (LWR), condition factor and sex ratioof twofish species, Mormyrus rume and Chrysichthys aluuensis. The study was carried out betweenAugust 2021 and January 2022 in Ovia River (Ighoraki), Nigeria A total of eighty-two (82) fishspecimens were collected during the study. Parameters of EWR were estimated. On an average, growth pattern, bin Mormyrus rume was 2.21 and 2.06 in Chrysithchys almensis indicatingnegative allometric growth pattern. The results indicated that the value of correlation coefficient
(1) for Mormyrus rume and Chrysichthys alauensis were 0.973 and 0.967, which were closer to1indicating that the length-weight relationship was highly correlated. The mean condition factor
(k) in Mormyrus rume was 1.03 and 1.01 in Chrysichthys aliensis. This indicated that fishspecies were in good condition during the study as mean k values were 1 in both species. Themean sex ratio across the study duration for Mormyrus rume and Chrysichthys aluuensis were1.13 and 1:3 respectively. The result indicated that males of Chrysichthys aluwensis were higher
than the females during the sampling period.
