Morphometric studies were carried out on penaeid prawns Penaeus monodon and Penaeus merquiensis as a first step towards developing a selective breeding programme for improvement of stocks in the trait tail weight. Twelve morphological characters were analysed for v a r i ability and their relationship with the tail weight. The females in both the species showed a higher coef- fecient of variation in almost all the characters. It was further observed that though many independent variables e.g. ENL, SSD, CD, EUL, CW etc. had a high correlation with the dependant variable (tail weight) a combination of exopod of uropod length (EUL) and carapace width (CW) explained more variation. It is therefore suggested that these two characters can b e measured for selection of initial brood stock without sacrificing the living prawns.
