This paper deals with relative growth of long carapace width (LCW) and carapace length (CL) with reference to short carapace width (SCW) in two species of edible crabs, namely Portunus pelagicus and P. sanguinolentus. The relationship between SCW and CL was found negatively co-related in both the species. Size-weight relationship showed that males are heavier than similar sized females in both species. Meat yield was found higher in P. pelagicus than P. sanguinolentus. Male P. pelagicus had 40.1 to 51.3% (average 44.5%
