Abstract: The present studies on the Length-weight relationship of Redbelly tilapia (Tilapia zillii) caught with gillnet was to determine the growth pattern and their well – being. The different mesh sizes of gillnet were used in this study. The total length (TL) and weight (g) of Redbelly tilapia were measured with ichthyboard and digital weighing balance respectively. Data were collected fortnightly for a period of six months. The length-weight relationship and condition factors were determined by Le Cren’s method. The data on length and weight of Tilapia zillii, varied between 11-26 cm and 28-330 g respectively. The slope (b) value of the length-weight relationship of Tilapia zillii was 2.88. The t-test showed that ‘b’ values were significantly different (p<0.5) from 3. Hence, the growth pattern of Tilapia zillii in the Lake was negative allometric. The condition factor obtained for Tilapia zillii was 2, indicating that their well-being in the Lake was normal.
