Length-Weight Relationship and Condition Factor of a Commercial Food Fish Labeo rohita (Hamilton, 1822) from Ghaghara River, Uttar Pradesh, India

Abstract

The present study provides first-hand information about the length-weight relation of Labeo rohita (Hamilton) from Ghaghara River, Uttar Pradesh. We collected 107 specimens and took length and weight for better conservation techniques and proper management for rohu. A total of 107 specimens were examined for the study, which has ranging from 25.2-56.13 cm TL (Total length) and 183.3-2409.78 gm (weight) were used for the study of LWRs and condition factors. Our study represented that L. rohita exhibited a negative allometric growth (b < 3) indicating that the fish grows faster in length compared to their weight. The values of the correlation coefficient (r2) and condition factor (K) are 0.8601 and 1.27 respectively. This research will be useful for fishery research, stock assessment, conservation, and estimation of the fish condition of this Himalayan River.
