Sažetak
A large assessment of Sparus aurata (Sparidae) nurseries along the eastern coast of the middle Adriatic was conducted during 2017 by locating and quantifying nursery microhabitats and estimating the settlement pattern. In total, 23 locations (3 replicas) of the 925 k m-long shore were monitored and S.aurata were recorded on 11 areas (47.8%). Their main characteristics, shallow, soft, transitional habitats (45.5 %) sheltered within coves, covered partially with seagrass meadows, made them vulnerable to human-induced habitat modifications. S. aurata settled along study area at the end of January. Maximum density observed reached 11 ind./haul in March and 13 ind./haul in April. The settlement rates were spatially variable. At a regional scale, higher settlement rates were observed within centre zones of study area (Šibenik) compared to those observed in the north (Zadar) and south (Ploče- Pelješac). Suitable nurseries along this shore seem insufficient for the replenishment of adult populations, which suggests that they depend on the migration of adults from the northern Adriatic in the autumn period. These results show that it is necessary to protect these scarce, small and vulnerable local nursery habitats and manage other nearby nurseries to ensure the survival of juveniles and their recruitment into adult populations.
