Se colectaron y analizaron un total de 96 estaciones distribuidas en cinco áreas de la Provincia de Esmeraldas durante los años 2004-2005. Se elaboraron gráficos de las especies (muestras de red de 50 µ) y la relación con los parámetros físicos y químicos. En la comunidad del fitoplancton presentó una variabilidad en la composición de especies, especialmente en el Terminal Petrolero durante septiembre del 2004 y disminuye en abril del 2005, la mayor densidad poblacional fue para el grupo de diatomeas. Las principales especies en el ambiente marino estuarino Climacosphenia monoligera, Pseudo-nitzschia paradoxa, Thalassiotrix frauenfeldii, Terpsinoe musica, Coscinodiscus excentricus. Las especies representativas en el ambiente marino Navicula tuscula, Climacosphenia monoligera, Lauderia boreales, Coscinodiscus concinnus, Cyclotella menenghiniana; las mismas que presentaron variabilidad en su distribución, registrando altas concentraciones celulares.Ninety six phytoplankton samples were collected and analyzed in five areas of the Esmeraldas Province during the years 2004-2005. Were elaborated graphic of the (with a net of 50 µ)and the relation with the parameters physical and chemical. The phytoplankton community showed variability in the composition of species, specially in the Terminal Petrolero, during september of 2004. Later in april of 2005, the high density poblacional it is belonged the diatoms group. The main species in the estuary environmental were following species Climacosphenia monoligera, Pseudo-nitzschia paradoxa, Thalassiotrix frauenfeldii, Terpsinoe musica, Coscinodiscus excentricus. The main species in the marine environmental were following species Navicula tuscula, Climacosphenia monoligera, Lauderia boreales, Coscinodiscus concinnus, Cyclotella menenghiniana; vich ones showed distribution variability, registered high cell of diatoms concentrations.
