This study describes the length-weight relation (LWR) of small indigenous fish Pethia ticto from Gomti River, Aamghat, Haliyapur, Sultanpur district 260 29N and 810 44E, 751m (msl) Uttar Pradesh, India. A total of 306 specimens were caught by random sampling method using traditional fishing gear as gillnet, cast net and dragnet of various mesh sizes from June 2016 to May 2017, once in a month. Total Length (mm) was measured from anteriormost part of the snout to the posterior-most part of the caudal fin and body weight (g) were taken by digital electronic balance. The analysis of data shows that the allometric coefficient is close to isometric value (3.0). Allometric growth indicates a more rotund population of fish when the values of growth coefficient are higher than 3.0 (b>3). If the value of growth coefficient is less than 3.0, the population of fish is known to be less rotund. Isometric growth indicates that the shape of fish does not change as it grows (b=3). The coefficient of determination (R2 ) was also found significant (=0.97). Fultonâ€™s condition factor further supports the results obtained ranged from 1.041 to 1.660 shows the degree of well being of a fish. This study is helpful in providing relevant information in the assessment of stock and estimation of the fish condition about its environment
