Abstract:
In the southwestern Atlantic Shelf, in northern Patagonia, the coastal-inner shelf area of El Rinc?n (38°-41°S) is relevant due to retention processes and the occurrence of a mid-shelf front (MSF), which provide favorable habitat for the anchovy Engraulis anchoita, from which other commercial species feed on. Here, we assess the protistan plankton (>5 ?m) composition and biomass during spring and summer of different years to explore the community structure at the base of the food web and its potential relation with the heterogenic spatial distribution of the anchovys life stages previously reported in the literature.
