Abstract: Mature females of M. masoniana were available only in June-July and December-January while in H. emphysetum, they appeared in collection throughout year. Maximum number of ovigerous females of M. masoniana were recorded in July (4 & 5) and January (3 & 4) while minimum in June (1 & 2) and December (1 & 1). In H. emphysetum, maximum ovigerous females were observed in March (5 & 4) and June (3 & 3) while minimum in May (0 &1) and October (1 & 1) during 2 years of investigation period. Fecundity was observed to vary from 430±36 eggs at 4.0 cm CW, 59 g weight and 3.8 cm Ab.W to 910±28 eggs at 5.7 cm CW, 97 g weight and 4.9 cm Ab.W with average fecundity 650±171 in M. masoniana. In H. emphysetum on other hand, fecundity was recorded to vary from 98±26 eggs at 3.4 cm CW, 33g weight and 2.9 cm Ab.W to 576±18 eggs at 4.9 cm CW, 89 g weight and 4 cm Ab.W. with average fecundity being 351±158 eggs. Correlation between fecundity vs CW, Ab.W as well as Weight of crab was recorded to be positive and significant in both the species.
