Keywords: growth, condition factor, Tilapia mariae, Ogun River.
The length-weight relationships and the condition factor of the fish Tilapia mariae were examined in the laboratory. The fish species attained a mean standard length in the range of 13.12±0.61 cm in male, while it was 19.83±0.76 cm in female. The growth in length relative to weight was negative allometric. There was variation in condition factor (k) for both sexes. The females were in better condition than the males whose k-values were higher during the dry and wet seasons. The sex ratio of Tilapia mariae in the reservoir was 1:3.12 (M: F), with September showing the highest sex ratio of 1:3.17 (M:F) and October showing the least 1:2.05 (M:F).
