The study was carried out to investigate the length, weight, condition of factor and the size distribution of two different species which were O. niloticus and S. schall from River Benue. The fish samples were obtained from Wadata fish market. The length-weight relationship was determined using Le standard method. Variation in standard length of S.schall range from 26.00 to 40.10cm, while standard length varied from14.00 to 21.01cm in O. niloticus. Similarly, total length ranged from 28.30 to 42.90cm in S. schall and bodyweight varied from 248.40 to 432.20g. The total length in O.niloticus ranged from 16.01 to 23.01cm and the bodyweight ranged from 66.60 to 86.20g. However the weight of S.schall was higher than that of O.niloticus and perhaps this was due to the condition of factor of the two different fish species and their feeding habits.
