Abstract

In this study, some of reproductive biological characters and gonadal development stages of ovarian tissue in 108 pieces of palaemon elegans shrimp, in the Gomishan wetland were reviewed during the end of December 1389 to June 1390. For this purpose, tissue sections were prepared from middle substances of the ovary of female shrimp monthly. Minimum and maximum of absolute fecundity ranged from 300 pcs and 2686 pcs. With increasing body size, the absolute fecundity of them increases and maximum of length range were 35-45 millimeters. Maximum redundancy of gonads in step 4 and step 5 was observed in April to June and in the final stage of egg development, egg volume reaches. to an average of 0.725 millimeters. It seems that fecundity of elegance shrimp in Gomishan wetland is much higher than other reported areas.
