ABSTRACT
The ichthyofauna of Imo River in Nigeria was
sampled for 6 months (MarchAugust) at 3 different locations, Umungwa Obowo in
Obowo Local Government Area of Imo State, Owerrinta in lsiala Ngwa South Local
Government Area of Abia State and Onuimo which is at the boundary between
Onuimo Local Government Area and Okigwe Local Government Area both in Imo
State. The three locations are about 45km apart. The fishing gears used were
cast net and seine net, the total fish specimen caught was 430. Thirteen fish
species were caught at Okigwe, eight at Owerrinta and eighteen at Unungwa.
Species like Tilapia, Oreochromis,. Chrysichthys, Labeo, Gavialocharax,
Citharinus, Odaxothrissa, Gnathonemus, Pellonulla, Petrocephalus, Hydrocynus,
Alestes, Sarotherodon and Prawn were caught at Umungwa Obowo. These species,

There is significant difference in total mean length between Oreochromis and
