The first case of a bloom for blue-green alga Nodularia spumigena in the Black Sea has been studied. The maximum abundance of the species in the bloom patch was 585.6·106 of filaments·per L−1, biomass − 6.2 kg·m−3. Mass development of the species was observed in mid July 2010 at 24.9-27.0 sea water temperature and 12.9-14.5 salinity. The dynamics of the abundance of N. spumigena and accompanying phytoplankton species has been analyzed. Possible reasons for the bloom of microalgae have been discussed.
