In this study, we investigate the diversity and spatiotemporal distribution of gelatinous zooplankton (GZ) in central Baltic Sea (coastal waters Gotland adjacent Eastern Western Basins), a region characterised by low salinity ecological sensitivity. Despite being largest brackish water body globally, knowledge about its GZ, specifically, medusae ctenophores, is limited. Our research synthesises existing literature, open-access data, local reports. Three to five GZ species occur within studied area, with common jellyfish Aurelia aurita dominating. Peak sightings A. happen between July October, whereas ctenophore Mertensia ovum scyphozoan Cyanea capillata display sporadic occurrences. We identify notable gaps understanding phenology food web impacts due historical neglect insufficient monitoring, particularly under low-salinity conditions (between 5 8), which restricts richness.

EOVs are an approach for globally usable data adhere Findable, Accessible, Interoperable, Reusable (FAIR) principles. Including routine collection reporting would significantly enhance regional global understanding, contributing holistic ecosystem view. Thus, advocate ocean observation frameworks comprehensively monitor populations their ecological, biogeochemical, socioeconomic roles. findings serve as crucial step towards implications climate change assemblages Sea, promoting marine management.

The diet of the invasive ctenophore Mnemiopsis leidyi in Gulf Trieste was examined during its peak occurrence summer and early-autumn months (July to October) from 2017 2019, through analysis stomach contents. Altogether 506 specimens were individually caught for analysis. A total 3215 prey items isolated identified. Copepods emerged as primary (relative abundance 66.7%), followed by cladocerans (7.7%), bivalve larvae (6%). Notably, M. constituted a significant portion (5.4.%), providing further evidence cannibalism within this species. also most commonly occurring leidyi. Most them represented calanoid cyclopoid nauplii (48.2%), harpacticoid norvegica (28.3%), calanoids (26.8%). Other frequently taxa (19.3%), (18.7%), cladoceran Penilia avirostris (16.1%). rate peaked July, coinciding with period limited food availability. Additionally, study revealed that fish eggs infrequently found stomachs However, presence massive aggregations may impact microzooplankton populations late or autumn, potentially leading competition small pelagic fish.
