This study was aimed to describe length-weight relationship and condition factor of 18 cat fish species belonging to five families of Indus River in Taunsa barrage from Punjab, Pakistan. The value of length weight relationship (LWR) equation and condition factor (K) ranged W= -0.249 TL0.79 – W= -2.803 TL3.55 and 0.07 – 1.69 respectively. The objective of this study was to determine LWR and condition factor of cat fish species of Indus River that could help in
conservation and management of ichthyofauna in the Indus Rivers, Pakistan
