Resumo: 	Planktonic information obtained in four fixed stations in front of Esmeraldas coast, Punta Galera, Puerto López and salinas is analyzed, during 1999-2000 and 2003-2006 periods. Temporal variability of phytoplankton and zooplankton densities between 2004 and 2006 were mainly determined by the oceanographic characteristics, and by the interrelations between the components of plankton and seasonal distribution of the organisms, as well. Higher phytoplankton productivity was determined in front of Esmeraldas, whereas the higher concentrations of zooplankton were obsrved in Puerto López, this evidences the predation at the first by the second trophic level. the phytoplankton composition in Esmeraldasis mainly influenced by the Esmeraldas river whereas in Port López, salinas and Punta galera the influence of oceanic wateris greater. During 2006, it was not registered an increment of plankton considered indicators species of ENOS event (warm phase). The phytoplankton species: &lt;i&gt;Cylindrotheca closterium&lt;/i&gt; and &lt;i&gt;Guinardia striata&lt;/i&gt; were the most abundant and frequent species during 2004-2006, wereas &lt;i&gt;Paracalanus indicus&lt;/i&gt; and &lt;i&gt;Oncaena media&lt;/i&gt; in zooplankton. The specie syphomedusa &lt;i&gt;Pelagia noctiluca&lt;/i&gt; was regsitered for a first time in ecuadorians waters.
