Abstract: Los estudios del zooplancton en diferentes áreas principalmente en el río Teaone, Esmeraldas y la zona marino costera frente a la ciudad que incluye, el área del balneario Las Palmas, en el último año se ha intensificado con el objetivo de obtener un conocimiento detallado de la presencia de estos organismos y las características físico-químicas que condicionan su abundancia y distribución.
The present study was carried out during the wet and dry seasons in the rivers Teaone, Esmeraldas, Petrolero Terminal and Palmas, for which stablished that a variability exists temporary space as for the abundance and composition of the communities zooplankton, especially the species of the taxa Chaetognatha, Cladocera, Caridea. The area of major productivity zooplanctónica associated with a high diversity was in the zone of Petrolero Terminal of Esmeraldas during the wet season. In the area Petrolero Terminal there was high abundance of Quetognatos's species represented by the dominancia of S. bedoti and S. neglecta in the wet season and during the dry season the dominancia was od S. enflata and S. minim which con be related principally by the seasonal variation of the parameter salinity, whereas the temperature was kept in a range of 25.9° to 28.4 °C during 2 season in study. The low zooplankton abundance and diversity registered in the river Teaone, there being registered the presence of scanty specimens of Macrobranchium rathbunae in the wet season. In the river Teaone were observed high values of potential of hydrogen in comparison with other areas in study, for what, it might catalogue that this area is in conditions of a deterioration of the quality of the waters, by light indications towards a pollution product of the antropogénica activities.
