Abstract
The present study describes the length-weight relationship (LWR) and condition factor of Xenentodon cancila (Hamilton, 1822) on a seasonal basis from upper Brahmaputra basin, NE India. All the relationships between total length and total weight are found to be highly significant (P<0.01) for both the sexes of the species throughout the period of study. The species exhibited allometric growth for most part of the study and found not to be strictly in accordance with the predicted cube law. Seasonal variation in the calculated “b” values for the species also observed ranging from 2.098 (in winter) to 3.401 (in pre-monsoon). Similarly, mean value of relative condition factor (Kn) ranges between 0.991 (in monsoon) and 1.149 (in winter) with minimum seasonal variations for both the sexes while mean value of Fulton’s condition factor (K) is found to be slightly higher in females than males except for monsoon.
