Spatio-temporal distribution of the fish Synodontis schall (Teleostei: Mochokidae) in Asa lake,Ilorin, Nigeria

Spatio,temporal distribution of Synodontis scha!l in Asa lake was studied for 24 months (March 1991 to February 1993). Distribution of individual was: 28.40 % (surface), 35.60 % (shore), and 36.0 % (bottom). Catches wilhin lhe habitat were nOl significantly differen!. Similarly catches within lhe ha...
