Length–weight relationships and condition factors of wild, cultured, and cultured loose-shell affected Penaeus monodon (2,609 specimens total) were studied from March to August 2007. The regression equation for healthy cultured shrimps was log W = −1.811 + 2.721 log L (r2 = 0.71); log W = −1.444 + 2.485 log L (r2 = 0.91) for wild shrimps; and log W = −1.112 + 2.237 log L (r2 = 0.92) for loose-shell affected shrimps. All shrimps showed negative allometric growth, although ancova indicated significant differences (P < 0.05) among them. This study presents the first known reference dealing with LWRs and condition factors of cultured, wild and loose-shell affected P. monodon.
