In this study, the prey composition of broad nosed pipefish (Syngnathus typhle) that has distributed in the Aegean Sea coasts was seasonally determined between the years of 2007 and 2008. The seasonal differences were determined in gut contents. In Spring, unidentified and vegetative tissues were the most important prey group in ten prey groups (chi(2), 10.0 p < 0.05). The chi-square test indicated that there was no significantly difference between the gut contents of female and male individuals (p > 0.05). Consequently, the variability of diet of samples was occurred by small sized preys and also larger preys in vegetation fields from the Aegean Sea coasts.
