The influence of reproduction activity on the feeding activity of blue swimming crab Portunus segnis from northwest of Persian Gulf, was examined. Sampling was performed by trawl net that 864 crabs was collection. After freezing, the samples were transferred to the laboratory in order for further analysis. The first, the biometry features (body weight, carapace width and carapace length) were measured then the stomach of each sample was surveyed. There was significant differences between the different food items (P<0.05), there was significant difference between the contents of ovigerous and non-ovigerous stomachs (P<0.05). Comparison of ovigerous and non-ovigerous crabs revealed that both groups fed on the same food items, but the frequency of occurrence of the food items was lower for ovigerous females and many stomachs were empty. This is partly explained by the fact that ovigerous females spend more time grooming their eggs.
