The First Case of a Bloom of Nodularia spumigena Mert. ex Born, et Flah. (Cyanophyta) in the Black Sea

摘要

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 10~6 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.
