abstract={No study relating to Harmful Algal Blooms (HABs) in the marine coastal waters of C?te d¡¯Ivoire has been carried out. Given their harmful effect, the aim of this study is to identify and quantify HABs in Ivorian waters and monitoring their temporal distribution. Weekly sampling was carried. Samples were fixed in formalin solution (5% final concentration) and afterward, were examined using a standard optic microscope equipped with a digital camera. The quantitative estimation of the HABs species was performed by counting with an inverted diavert microscope, using Uterm?hl¡¯ method. Seventeen (17) HABs were determined using the species¡¯ identification detailed in the literature. They are divided into two groups, those which don¡¯t produce toxins like genus <i>Ceratium,</i> <i>Dictyocha,</i><i> </i>and<i> </i>two species of <i>Prorocentrum,</i><i> </i><i>P.</i><i> </i><i>micans,</i><i> </i><i>and</i><i> </i><i>P.</i><i> </i><i>gracile</i> and those which produce toxins like genus <i>Dinophysis,</i><i> </i><i>Pyrodinium</i><i> </i>and species<i> </i><i>Prorocentrum</i><i> </i><i>rhathymum</i>. The lowest densities of HABs were observed during the long and short rainy seasons and the highest were recorded in september with a significant peak on september 11. The species responsible for these high densities are: <i>Ceratium</i><i> </i><i>furca</i> (8444000 Cells.L<SUP>-1</SUP>), <i>Dinophysis</i><i> </i><i>caudata</i> (4960000 Cells.L<SUP>-1</SUP>) and <i>Protoperidium</i><i> </i><i>divergens</i> (2000000 Cells.L<SUP>-1</SUP>). These high values are due to upwelling. The processes that develop during upwelling, in particular the rise of nutrients, are responsible of high biological productivity, hence the high values of HABs observed during this period.},
