Abstract: The Length-weight relationship of Glyptothorax ngapang Vish. & Linthoi, 2007 and Channa punctata (Bloch, 1793), collected from the Senapati District of Manipur, have been studied. Based on 120 specimens of Glyptothorax ngapang (42.6mm to 124.7mm total body length and 65.0g to 123g in weight) and 50 specimens of Channa punctata (124mm to 185mm total body length and 20.0g to 58.0g in weight), the regression equations were calculated to be Log W= 42.4424 + 6.7109 Log L for Glyptothorax ngapang and Log W = -51.1305 + 5.827 Log L for Channa punctata. The graphs for the weight of fish plotted against total length show an exponential curve in both species. The average relative condition factor (Kn) in both cases was found to be 1, indicating their well-being.
