Variations in physical-chemical factors, species composition, abundance and biomass of phytoplankton assemblages, as well as their responses to environmental factors, were investigated in Grand-Lahou Lagoon from June 2006 to February 2007 (Ivory Coast, West Africa). The hydrosystem and the growth of anthropogenic activities on its hillsides particularly favored the high rate of soluble reactive phosphate concentration (0.32-2.1 mg/L) and nitrate concentration (0.09-7.93 mg/L). Consequently, high phytoplankton densities (56-156 106 cell/L), low transparency (0.45-0.90 m) and high suspended matters rate (3.60-22 mg/L) were observed. The 97 species were represented mainly by Diatom comprising 42 species (42.3%), Chlorophyceae with 23 species (23.7%), followed by Cyanobacteria, Euglenophyceae and Dinophyceae with 19 species (19.6%), 11 species (11.3%) and 3 species (3.1%) respectively. Species composition of phytoplankton was typical of eutrophic conditions. The occurrence of filamentous Anabaena planctonica Brunnthaler, Oscillatoria limosa C.Agardh ex Gomont, Pseudanabaena sp., Oscillatoria princeps Vaucher ex Gomont, Planktothrix agardhii (Gomont) Anagnostidis & Komárek and colonial Microcystis aeruginosa (Kützing) Kützing in high numbers may highlight pollution stress in the lagoon. The proliferation of the Cyanobacteria encountered was controlled by the nutrient level (nitrate) and transparency. The physico-chemical characteristics, Margalef, Shannon and Equitability indices indicated pollutions stress and dominance by a few species.
