Massive amounts of mucilage aggregates have been observed in different marine environments worldwide but the northern Adriatic seems to be most severily affected. Our observations indicated that the phenomenon passed through a characteristic "life cycle" and variable phytoplankton composition assessed by pigment biomarkers (HPLC). The number of phytoplankton groups decreased as the aggregates aged and diatoms increased in relative biomass (up to 92,7%). Phytoplankton biomass in seawater was similar in years with and without mucilage. Significantly higher contributions to the total biomass of 19' -hexanoyloxyfucoxantin-containing phytoplankton (prymnesiophytes) were found in the upper 10 m preceding the mucilage phenomenon, followed by prevalence of diatoms in summer.
