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
