Zooplankton plays a key role in the marine food webs, and it represents the main food source for small pelagics, one of the most exploited resources in the Adriatic Sea. In order to deepen our knowledge of zooplankton assemblage structure and trophodynamics in one of the most productive areas of the Mediterranean sea, but at the same time highly impacted by human activities, community and Stable Isotope Analyses (SIA) were performed on zooplankton samples. Here SIA data are provided. Zooplankton samples were collected on board R/V G. Dallaporta during the acoustic survey MEDIAS 2019 geographic subarea (GSA) 17 and GSA 18 (Leonori et al., 2021, https://doi.org/10.12681/mms.26001) that took place in June-July 2019, in the continental shelf waters of the western Adriatic Sea. Vertical hauls were performed using a WP2 plankton net, starting from 3 m above the bottom (or from 100 m depth in the deepest hauls), to the surface. Zooplankton samples were frozen on board and analysed in the laboratory to characterize the planktonic community, both at assemblage and trophic structure levels. After taxonomical identification, samples were dried and analysed through an elemental analyser (Thermo FlashEA 1112) for the determination of total carbon and nitrogen and then analysed for ?13C and ?15N in a continuous-flow isotope-ratio mass spectrometer (Thermo Delta Plus XP) (Post et al., 2007, https://doi.org/10.1007/s00442-006-0630-x).
