This study presents the first results of frame net sampling realised in the pelagic environment of the Marmara Sea, Türkiye. Samplings were conducted from 12 stations located in the Marmara Sea with three frame net survey between December 2021 and March 2022. Tows were realised with oblique tows during 10 minutes. A total of 82 individual belonging to 6 varied families and 6 species were identified. The late postlarvae of demersal species distribute pelagic habitat before settlement were found more abundant via pelagic juveniles from the frame net catchs. Although the mean biomass of the species were low, the Gaidropsarus mediterraneus was found the most dominant species. It was found that frame net samplings enable to obtain late postlarvae and early juveniles, which escape from plankton nets due to the high swimming capabilities and escape from seine nets due to the selectivity pattern of commercial nets.
