The Adriatic Sea is a semi-enclosed basin in the Mediterranean. Due to constant fishing pressure, fish stocks of numerous economically important species are currently in the state of overfishing. Therefore, the study of fish early growth stages is imposed as one of the ways to better understand the dynamics of populations in order to protect them. For the purposes of this work, ichthyoplankton samples were collected from 33 stations in the wider area of the Jabuka Pit in the summer period of 2019 and 2020. A total of 20 different fish species classified into 12 families were isolated in the samples. The rate of biodiversity was slightly higher in the first year of the study, and the abiotic parameters of both years corresponded to those expected for the Jabuka Pit. The anchovy Engraulis encrasicolus dominated the collected ichthyoplankton samples (67.82 %) during both years of the study. Among the other commercially important species, hake Merluccius merluccius, red mullet Mullus barbatus, bullet tuna Auxis rochei, little tunny Euthynnus alletteratus, Atlantic chub mackerel Scomber colias and Atlantic horse mackerel Trachurus trachurus were found. No new and previously unrecorded species were found in the research area. Collected and isolated species were expected since the research period coincides with the spawning period of all found species. This research contributes to the understanding of the ecological relationships of marine organisms in the open central Adriatic Sea.
