The condition factor, length-weight relationship and abundance of Ilisha africana from Nkoro River in the Niger Delta area of Nigeria was studied for a period of one year (January-December 2008). From a sample size of 113 specimens, K value was 0.999 and the exponential equation was Wt=0.05998 (TL)^2.719, indicating an isometric growth pattern. The highest catch was recorded in February (1.61), followed by March (1.00), January (0.90), December (0.60) and June (0.10). April, May, July, August, September, October and November recorded no catch during the study. The highest condition factor value (1.58) was recorded in February and the lowest (0.00) in September. The highest catch per unit effort (1.13) was recorded in stations 2 and 4, followed by station 1 (1.12) and station 3 (0.72 each). Ilisha africana in Nkoro river is in a stable environment and was more abundant in the dry season months of February, March, January and December.
