Studies on Fish Diversity and Condition Factor of Fish Species of Ogbei Stream, Southern Nigeria

Abstract

The present study which is aimed at studying the condition factor of fish speciesof Ogbei Stream was carried out for a period of six months (January – June 2005). Eight (8)species belonging to seven (7) families and four (4) orders were identified from a total of 44individuals. The family Cichlidae was more abundant and more diversified having three (3)species namely Tilapia zilli, Oreochromis niloticus and Parachana obscura. Other familieshad one (1) species of fish each. Tilapia zilli had the highest percentage composition(34.01%) followed by Clarias anguillaris (25.00%). Parachana obscura, Labeo senegalensisand Erpetoichythes calabaricus had equal percentage composition of 02.27%. Five (5,62.5%) of the fish species had condition factor greater than 1.0 while three (3, 37.5%) hadcondition factor value that approximately ranged from 0.1 to 1.0. Thus the fishes especiallyMalapterurus electricus are doing well. It is envisaged that this study will serve as a baselinefor future work and rational management of fishery resources of Ogbei Stream.
