This study describes the length-weight relationship (LWR) and condition factor for three important freshwater fish species (Garra mcclenlandi, Danio aequipinnatus and Crossochelius latis) collected from drainage system of Mon, Nagaland, India from 2022 to 2023. During survey a total of 278 specimens of mixed population were examined. 95% confidence level of b values (regression coefficient) of Length-Weight Relationship (LWR) ranged from 2.3616 - 3.1485 indicating positive allometric pattern of growth for D. aequipnnatus, while G. mcclenlandi and C. latis showed negative allometric growth. The highest condition factor (k) 1.0993 was observed in D. aequipnnatus, lowest in G. mcclenlandi with 0.8126 while r2 > 0.90 for all the three species.
