Summary The present study describes the length–weight parameters of Wallago attu and Sperata sarwari from the Indus River, southern Punjab, Pakistan with W = 0.001698 L 3.27 for W. attu and W = 0.001698 L 3.28 for S. sarwari . The values of the slope b are significantly higher than b = 3.0, which shows that the weight grows more rapidly as compared to the cube of the length. Thus it was concluded that body proportions changed as fish grew in size.
