Abstract: Food composition and distribution of gelatinous macrozooplankton (Aurelia aurita and Mnemiopsis leidyi) were determined during this study. Dominant main food of A. aurita and M. leidyi were found Copepoda (41.7% and 31.6%) and Bivalvia (16.3% and 27.6%) according to numerical occurrence. While the numerical and frequency rates of fish eggs and larvae in the A. aurita food composition were 0.8% and 1.5%, respectively. These values were determined as 0.9% and 1% for M. leidyi. Zooplankton was found as feeding preferences of A. aurita and M. leidyi in terms of food composition. Seasonal differences have been observed in biomass and abundance of species. Highest abundance and biomass were 16.67 n.m-2 and 124.17g.m-2 for A. aurita, 51 n.m-2 and 82.5 g.m-2 for M. leidyi, and 2.5 n.m-2 and 17.29 g.m-2 for B. ovata. M. leidyi showed correlation with temperature (p<0.05).
