The relation among bacteriopbnkton, nannoplankton. microzooplankton, and some abiotic factors in the oligotrophic oceanic water, of northern Cuba was analyzed. Samples were obtained at three different depths from 40 stations during February 1997. Nannoplankton, microplankton and bacterial biomass were determined by standard methods, including ceH counting and epifluorescence microscopy. The spatial distribution pattcrn uf hcterotrophíc components showed a higher richness at western and eastern zones of the studied region, as in areas near La Habana and Matanzas bays. From the surface layer to 1% irradiance depths, the highest relative contribution was of microzooplankton and bacterioplanklon, whereas the mixed (thermocline) layer was dominated by nannoplankton. The dynamic regime characteristic of this zone and the effect of enriched water from shelf and bays has influence on the behavior of the planktic fractions.
