The investigations on length-weight relationship and condition factor of the African big barb Labeobarbus intermedius (Rüppell, 1836) in Ethiopian water bodies have shown varied pattern including nearly isometric (b≈3), negative (b<3) and positive (b>3) allometric. The Fulton condition factor (K) of L. intermedius is high (1.73) in Lake Ziway, however, declined in most rivers and lakes and also exhibits seasonal variation. Fish had a better body condition (2.73) during wet season in Angereb and Sanja Rivers. There is variation in condition factor with respect to sex in which females had better body condition (1.88) in Lake Ziway. The length-weight relationship and condition factor of L. intermedius is correlated with availability of food and water quality parameters justifying the need for effective management of this fish stock for conservation and continued fishing.
