Description parameter |
As no threshold values for plankton community within D1 are agreed for the Adriatic Sea either at national or subregional /regional level, this prevents us from providing the required support of the assessment. In the absence of upper acceptable values, there is no possibility of quantitatively expressing the extent of GES achievement in the reporting tables. In the text report submitted by Croatia we used several indicators for analyzing both components of Pelagic habitats (phyto- and zooplankton) such as biodiversity indices, abundance ranges, community structure – species' lists, relationships between functional groups etc., and applied those to different pelagic habitat types in the eastern Adriatic Sea (coastal, variable salinity, channel areas, continental shelf). The values are then compared to the preceding reporting period (MSFD Art.8, Initial assessment) and to available other historical data from the same areas, and GES determination is obtained through expert judgement. |

Description criteria |
For the element zooplankton GES is achieved. The assessment is based on mesozooplankton community analysis which indicated that spatial and temporal variability of zooplankton groups and species is consistent with predominant abiotic and biotic environmental conditions, and the relative contribution of groups and species is in accordance with the observed habitat condition, showing no apparent adverse effects of anthropogenic pressures. |

Description element |
For this element GES is achieved. The assessment is based on phytoplankton analysis, the recorded spatial and temporal distribution trends as well as relative abundances of phytoplankton groups which are within usual values and in accordance with environmental conditions. High biodiversity, low incidence of bloom events and relatively low phytoplankton biomass (as reported for Descriptor 5) indicate that anthropogenic pressure does not adversely affect phytoplankton abundance or biodiversity, thus ensuring the long-term sustainability of phytoplankton community. |
Based on the analysis of mesozooplankton community, spatial and temporal variability of groups and species are in accordance with the prevailing abiotic and biotic environmental conditions. The relative contributions of mesozooplankton groups and species are in accordance with the observed habitat conditions, showing no apparent adverse effects of anthropogenic pressures. |
