Resumen:ABSTRACT The length-weight relationship (LWR) is the most important parameter; those are applied for the assessment of fish health and growth. The present study was carried out to know the gap and provide useful information for fish management and conservation in the Ranikot lotic water body. Five Cyprinidae fish species (Labeo bata, L. pangusia, L. barbus, L. potail, and L. porcellus) were collected from the lotic water body to calculate the LWR in order to assess the population status of the lotic water body. All of the five species showed significant positive correlation (r2=>0.5) between length and weight. The values of the growth exponent ‘b' in the LWR ranged from 2.089 to 3.193. LWR indicated an isometric pattern of growth for L. barbus (b=2.959) and L. potail (b=2.718), while a little positive allometric growth (b=3.193) was observed in L.pangusia. Furthermore, the negative allometric growth was observed for Labeo bata (b=2.337) and L. porcellus (b=2.089). While, the regression value shows median correlation (r2=<0.8) except L. barbus (r2=0.852) for all other four species. The present investigation is likely to be useful for application in fish biology and fisheries management.
