    The knowledge of some quantitative aspects of fish such as length-weight relationship and condition factor, serve as important tools For the study of fishery biology. The fish samples were purchased from the landings of fishcrfolks of River Uke using fishing gears such as cast nets, traps, hook and line. These were carried out during the rainy and diy seasons for three times monthly from March to August 2017. The total length and weight of the 219 Barbus occidentalis obtained from River Uke were recorded as follows; the weight of Barbus occidentalis sampled ranged from l5.0-996.9g and was determined to the nearest O.lg with the aid of electronic weighing balance model BL20001. The total length, 10.7-43.5cm was recorded using meter rule to the nearest 0.1cm. The length and weight relationship of Barbus occidentalis showed positive correlation (r=0.858) in both sexes. The regression exponent (b<3) showed negative allometric growth pattern. The mean condition factor (K) was (1.0645) in both sexes which showed that the condition and the well being of Barbus occidentalis were good in River Uke. This may be attributed to the availability of food materials and good physicochemical parameters of The River.
