Abstract

In the coastal waters of Mauritania three stable zooplankton community 1) community upwelling zones cape Cap Blanc, situated in the north of the study area; 2) community neritic zone in the highly productive coastal area; 3) community oceanic zones, remote from the coastline were identified in winter 2007/08 and 2009/10. Changes in the structure of these communities depended on the hydrological conditions, and, in particular, were associated with a decrease in the intensity of upwelling. This resulted in a decrease in the zooplankton abundance and species diversity of selected communities. Temora turbinata, an indicator of water of southern origin, was dominant in the community of the cape Cap Blanc in 2009/10 as a result of inflow of warm waters into the north district. A change in dominant species in the community oceanic zones was due to an increased proportion of neritic species. Composition of dominant species of community neritic zone remained the same.
