  Abstract

The impact of grazing by natural assemblages of microzooplankton was estimated in an upwelling area (Concepción, Chile) during the non-upwelling season in 2003 and 2004. Seawater dilution experiments using chlorophyll-a (Chl-a) as a tracer were used to estimate daily rates of phytoplankton growth and microzooplankton grazing. Initial Chl-a concentrations ranged from 0.4 to 1.4 mg Chl-a m-3 and phytoplankton prey biomass and abundance were numerically dominated by components <20 µm. Phytoplankton growth and microzooplankton grazing rates were 0.19 - 0.25 d-1 and 0.26 - 0.52 d-1, respectively. These results suggest that microzooplankton exert a significant removal of primary production (> 100%) during the non-upwelling period.
