Some aspects of the biology of Tilapia zilli were studied using a total of 420 males and females fish specimens caught in Kanye dam, Kano State Nigeria, from May to August, 2014. The fish mean length ranged from 8.4 -14.2 cm while mean weight ranged from 32.4 -89.3g. The fish indicated positive isometric growth pattern with a ‘b’ value of 3. Analysis of the stomach contents showed that the fish consumed algae (32.28%), insects (25.37%), fish parts (17.66%), decayed food particles (16.91%) and unidentifiable materials (7.14%). The physicochemical parameters were favourable and condition factor (k) obtained signifies that Tilapia zilli species were living in a good condition in Kanye Dam.
