Length-weight relationship of Lepidocephalichthys guntea (Hamilton, 1822) from Haora River, Tripura, India

Abstract

Length-weight relationship of Lepidocephalichthys guntea was studied separately for male, female, unknown and combined (male, female and unknown) on a monthly basis between January 2017 to December 2017 from Haora River, Tripura, India. In the study, a positive allometric growth (b>3) was observed among female, unknown and combined population, whereas the male population showed negative allometric growth (2.91). The correlation coefficient value was estimated at 0.929, 0.937, 0.904 and 0.941 for male, female, unknown and combined, respectively. The total length (TL)-Weight (W) relationships were found to be W=0.0090TL2.91, W=0.0056TL3.19, W=0.0048TL3.24 and W=0.0051L3.22 for male, female, unknown and combined L. guntea, respectively.
