| 要約: | Gelatinous zooplankton, widespread in pelagic environments, pose a challenge for surveillance due to their delicate, see-through bodies. Their presence often seems irregular, with fluctuating populations occasionally forming dense swarms. These efficient and non-selective feeders compete with fish for resources, and their abundant proliferation can alter the marine food web and result in ecosystem degradation. Hence, monitoring gelatinous zooplankton is crucial. In this study, we document their encounters over six years along the northeastern Adriatic coast, an important spawning area for small pelagic fish now experiencing frequent gelatinous zooplankton blooms. We compare findings from the north to those in the southern Adriatic. Continuous monitoring revealed that the invasive ctenophore Mnemiopsis leidyi, predominantly present in the northern basin, significantly altered the taxonomic composition, temporal occurrence, and intensity of gelatinous zooplankton blooms, shifting dominance from native to introduced species. |
