Sustainable management of fish stocks requires a good knowledge of growth parameters. From October 2016 to September 2017, 1091 specimens were sampled in four areas of Taabo Lake, in order to study Parailia pellucida length-weight relationship and condition factor. Growth of immatures and matures specimens is allometric in favor of weight. Females have positive allometric growth (b = 4.5) while that of males is negative allometric (b = 2.88). Regression equations were, respectively: W = 0,115LS4,58 for immatures, W, = 0.099LS3.73 for matures, W = 0.107LS4.17 for immatures + matures specimens, W = 0.117LS4.5 for females, W = 0.083LS2.88 for males, and W = 0.107LS4.13 for females + males. Determination coefficient for immatures and matures is, respectively, of 0.21 and 0.18. It reaches 0.13 for females and 0.15 for males. Immatures (0.96 ± 0.74) and matures specimens (0.93 ± 0.7) have substantially the same condition factors. Females (Kc = 1.06 ± 0.93) condition factor is relatively better than that of males (Kc = 0.93 ± 0.72).
