The present study was undertaken to assess length-weight relationships (LWRs) of Wallago attu (Bloch and Schneider, 1801) from Manchar Lake, in Pakistan. A total of 251 specimens collected from August 2011 to April 2012 were examined. Length-weight equations were W = 0.00464 L 3.0819 (combined), W = 0.00387 L 3.120 (males) and W = 0.00632 L 3.00892 (females).
