Regression analysis was performed on length–weight and length–length measurements of Penaeus monodon (n=3270 individuals) including carapace length, body length, total length and body (wet) weight of different life stages (nursery, growout and broodstock), sexes (female and male) and sources (pond and wild). Regression lines differed among the life stages and between the sexes and sources at the broodstock stage. Nursery and growout P. monodon showed a greater weight gain per unit length than broodstock. With bigger females, size dimorphism appeared only at the broodstock stage; males and females showed similar sizes in nursery and growout. Equations (including a, b and r) for interconversions of length and weight are reported for the different stages, sources and sexes.
