Justification for non-use of criterion |
HELCOM (2018a) Five indicators were used in the assessment of the status of HOLAS II pelagic habitats: 1) “Average zooplankton size and total abundance”, 2) “Seasonal change of dominant phytoplankton groups”, 3) “Diatom / Dinoflagelate index”; 4) "Chlorophyll-a" and 5) "Cyanobacterial bloom index". The applicability of the indicators to the Lithuanian sea area is analyzed in the report. The indicators are applicable to habitat AD.N5 “Baltic Sea Photographic Oxygen Pelagic Zone above the Halocline” as the assessment indicators for other habitats HELCOM (2018a) have not been developed.

The characteristics of pelagic habitats and the assessment of the prevailing trends were analyzed in 2010-2017. Hydrological data of the Baltic Sea. In general, a comparative analysis of hydrographic characteristics (temperature, salinity, oxygen, pH, water transparency) in 2006–2011 and 2012–2017 did not show significant changes in physico-chemical conditions in pelagic and benthic habitats.
