Abstract

Racial analysis of Plotosus canius of two localities, viz. Hooghly-Matlah estuarine system and Chilka Lake, done by testing the significance of generalised distance between selected morphometric measurements of two samples, by computing Mahalanobis's D², indicated morphometrically homogeneous stocks. It can, thus, be concluded that populations of these two localities, originally been drawn from the same stock inhabiting Bay of Bengal and become endemic to their specific locality during course of time, have not changed in their morphometric characters in their new localities.
