Length–weight relationship for three estuarine fish species from the Chilika Lagoon, India

Abstract

We investigated the length–weight relationships (LWRs) for <em>Sillago vincenti </em>McKay, 1980<em>, Triacanthus nieuhofii </em>Bleeker, 1852 and <em>Terapon puta </em>Cuvier, 1829 from the Chilika lagoon in India. Sampling was conducted in central sector of the Chilika from April to November of 2017. Specimens were caught in mono-filament gill nets of mesh size 28-36 mm and fixed set nets of mesh size 16-24 mm. From LWR estimation, the determined intercept (<em>a </em>value) and slope (<em>b</em> value) were found to be 0.007 and 3.039 for <em>Sillago vincenti</em>, 0.010 and 2.997 for <em>Triacanthus nieuhofii</em> and 0.008 and 3.156 for <em>Terapon puta</em>. The relationships between length and weight in all three species were highly correlated (<em>p </em><0.05).
