The morphology, abundance, condition factor and length-w eight relationship of Ethmalosa fimbriatafrom Nkoro River in the Niger Delta area of Nigeria was studied from January-December 2008. The bodydescription of E. fimbriata from Nkoro River was; Dorsal spine (total): 0, Dorsal soft rays(total): 16-19, Analspine: 0, Anal soft rays: 19-23. The m outh is sharply upw ard and V-shaped. Caudal fin is deep chrome withlong and pointed tips. The upper jaw contains distinct median notch, into which tip of lower jaw fits. Lowergill rakes are long, fine and numerous, often 3 times as long as gill filaments; upper gill rakes bent. There isa faint dark spot behind gill cover sometimes followed by others. The dorsal fin tip is black with golden tintson the body. The scute is 16-19, pre-pelvic, 10-13 post and scales in lateral series is 37-42. The highest catchwas recorded in January (8.16), followed by February (4.21), May (1.65), March (1.40), April (1.11) andOctober (1.10). June (0.87), December (0.32), November (0.20) and July (0.14) were less than 1. No catch wasrecorded for August and September during the study. T he highest catch per unit effort (5.62) w as recorded instation 2, followed by station 1 (5.04) and station 4. The least catch per unit effort (3.75) was recorded in station3 . From a sample size of 1200 specimens, K value was 0.946 and the exponential equation was Wt = 0.162(TL)3.199, indicating an isometric growth pattern. The highest condition factor value (1.00) was recorded in Mayand the lowest (0.6) in September. This was an indication that the beginning of rains favors E. fimbriata thanmid rains.
