Abstract

The annual breeding cycle of the crab, Barytelphusa cunicularis, was determined by measuring monthly the size of the gpnad relative to the size of the animal. The peak of gonad size appeared in rainy season (June to September) showing the maximum breeding activity during these months. Histological observations of the monthly gonads revealed that the ripening of the gonads started during March and extended upto May. By June the gonads of most of the individuals attained full maturity and spawning began. Spawning terminated by the end of September and the gonads entered a quiescent period.
