Morphometric variables were measured to detect variation among the random population samples of Penaeus monodon from east and west coast - Kochi, Calicut, Mangalore, Karwar, Kakinada and Chennai of India. Among these variables, PCL showed the highest correlation with the tail weight (TLW) in both males (0.9605) and females (0.9639). Truss network analysis of 26 measurements from the six centres were log transformed and were subjected to Principal Component Analysis and accounted a total of 89.15% variations in truss measurements data and showed no separate cluster formation in the plot of sheared PC scores and hence confirm homogeneous stock structure.
