Popis:	A total of 112 stomachs of the Great Pipefish, Syngnathus acus Linnaeus, 1758 (56 females and 38 males), was collected in Izmir Bay (Aegean Sea) and analysed in order to determine the feeding habits. 95 specimens (85.6%) were found with prey items in their stomachs. Zooplanktonic organisms were the main food and in terms of numerical (NO%) and frequency (FO%) of occurrence, four main prey categories were determined in the gut content of this species. The most dominant group was found to be harpacticoid copepods (33.6% NO; 57.7% FO), followed by Amphipoda (22.3% NO; 38.2% FO), cypris larvae (12.8%NO; 21.9%FO) and decapod crustaceans (9.5% NO; 16.3% FO), respectively. The numbers of their occurrence indicated that there were significant differences between the seasons. Seasonal differences in the gut content were found in 9 prey groups in spring (p
