Los objetivos del presente estudio son:- Establecer el estado actual del plancton en el estero Santa Rosa, estero Jambelí y río Jubones durante las fases de flujo y reflujo. - Determinar la productividad, dominación y diversidad del plancton presentes en el área de estudio......During the study was colected samples water on superficial at 27 stations, it was distributed in the Port Bolívar stuary with maing goal it to know primary productivity. the samples of plankton was colected in two phases: flux and reflux during the days 3 to 18 of july-2002. The diversity phytoplankton was identified to method Uthermohl 88 species in the lawyer superficial and 96 species were determined in samples net of 50u. In the phytoplankton community the diatoms were dominant and lower concentration the dinoflagellates, silicoflagellates, cyanobacter and cocolithophorides. In cell count the species the most dominant at the area were Skeletonema costatum and Pseudonitzschia delicatissima, in the net (50u) samples were registered the stuarine and benthic species: Skeletonema costatum, Cyclotella menenghiniana. It was destacated that the most phytoplankton diversity found in the areas river Jubones and the Santa Rosa stuary during the phase flux. The zooplankton community was regist.....
