Description :
Decapod crustaceans like crab, prawn, lobster and some molluscs are commercially important as they are with high nutritional value. In the present investigation, the reproductive cycle of freshwater crab, Barytelphusa guerini was studied by measuring percentage of different reproductive phases of male and female crab. The annual reproductive cycle of the crab, Barytelphusa guerini was studied during the year 2015 by observing the colour of gonads, calculating gonad index and measuring carapace length. The gonads of the most individuals attained sexual maturity and spawning began in the months of June and July. The ovarian index is ranged between 0.789 ± 0.19 to 4.872 ± 0.022. The testis index was ranged between 0.457 ± 0.003 to 2.459 ± 0.015. The colour of the gonad varies in different reproductive phases.
