We evaluated phytoplankton abundance, composition and trophic state of the EbriÃ© Lagoon on the basis of data taken in the period of June 2006 to February 2007. Sampling was performed at 13 stations in lagoon. Among three identified Cyanobacteria orders, Oscillatoriales dominated the peuplement with 47.62%. The distribution of the Oscillatoriales orders shows a predominance of genera Oscillatoria mainly composed of Oscillatoria
, Oscillatoria princeps
and Oscillatoria limosa.
The Chroococcales and Nostoccales constitute about 28.57% and 23.81% respectively of the total taxa. The blooms of Cyanobacteria in the lagoon were contributed by seven species. Those are Cylindrospermopsis raciborskii
, Anabaena flos-aquae
, A. planctonica
sp., Oscillatoria limosa
, Lyngbya martensiana
and Microcystis aeruginosa
. Abundance and seasonality of Cyanobacteria observed, characterized the EbriÃ© Lagoon as a highly eutrophicated environment. The NO3âˆ’
, SiRD and PRD, salinity regime and tranparency availability played important role in determining the distribution, diversity, and composition of Cyanobacteria communities.
