El objetivo del presente estudio es conocer la distribución cualitativa y cuantitativa de las especies del fitoplancton, zooplancton e ictioplancton y su relación con las condiciones ambientales durante el período en estudio......The present work includes/understands the study of the qualitative and quantitative temporary variability of the phytoplankton, zooplankton and ichthyoplankton in the shores of the Santay Island, of the Province of the Guayas. For the effect 16 samples, obtained during november of the 2000 and january of the 2002 were analyzed. 38 species of phytoplankton in water samples and 51 species in network samples were identified (50u). The diatoms were dominant and in smaller concentration the dinoflagellates ones, cianobacterys, silicoflagellates, and tintinides. The cellular biomass was represented mainly by Skeletonema costatum, Paralia sulcata and Coscinodiscus excentricus, species that were abundant in the study area. In network samples species were observed estuarys and benthicas: Actinoptychus senarius, Coscinodiscus excentricus, C. concinnus, Polymixus coronalis, Cyclotella menenghiniana, characteristic of a high fertility. During year 2000 a smaller zooplanctónica biomass with a varia.....
