Freshwater crab, Sodhiana iranica, is an endemic gecarcinucid crab that has been recently reported from Southern Iran. This research examined some reproductive aspects of S. iranica from Eelood freshwater spring, Southern Iran. Crabs were haphazardly sampled from April 2012 to April 2013, on a bimonthly basis. Measurements of Gonado-Somatic Index (GSI), Hepato-Somatic Index (HSI), oocyte diameter, and other aspects such as carapace width (CW) and total body weight (TW) were made in the captured specimens. Results showed a single seasonal reproductive cycle. Maturation and spawning occurred from December 2012 to April 2013 during the study period. The peaks of HSI were observed in April 2012 and February 2013. The oocyte diameter showed its most significant increase between August 2012 and February 2013. Considering the single seasonal breeding of S. iranica, a correct management, during the reproductive cycle, is necessary to support a healthy stock of this crab. Rev. Biol. Trop. 65 (1): 365-373.
