The first case of a water bloom by Nodularia spumigena Mert. ex Born. et Flah. (Cyanophyta) in the Black Sea

Alexandrov B.G., Terenko L.M., Nesterova D.A.

The first case of a water bloom caused by cyanobacteria of 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.
