    Yem, I.Y.; Sani, O.A.; Mshelia, M.B.; Onimisi, H.U.
    The length weight relationship and condition factor of Hemichromis fasciatus from Kainji Lake was studied. One hundred and twenty seven fish samples of total length ranging from 6.50cm 15.50cm and weigh between 4.00g and 60.00g collected between August 2006 and June 2007 were analyzed. Results showed that a, b and r - values were 0.0042, 3.442 and 0.966 respectively, while the condition factor (CF) values varied from 0.67 2.42 with mean of 1.203. The fish exhibited positive allometric growth pattern. The condition of the lake is favourable for the survival of the fish species.
