Abstract:

In order to evaluate mesozooplankton�??s distribution and diversity within the south Atlantic Moroccan coast, two surveys were carried out between Cape Blanc (21°N) and Cape Boujdour (26°N) during two seasons (autumn 2011 and summer 2012) hydrologically different. Referring to densities distribution and structural indexes measured of the population, a clear difference between the south part of Dakhla region (24°N) and north is noticed. The south part remains the richest and more diversified. The cluster analysis has confirmed the same results. Actually, this area is extremely rich in both phytoplankton (primary production) and zooplankton (secondary production). The group of copepods is clearly dominant in all stations sampled during both seasons (more than 90%) followed by cladocerans and chaetognathes. During fall, copepods composition is dominated by the species Oncaea venusta (44%), Clausocalanus arcuicornus (18%) while in summer Acartia clausi (18%) and Clausocalanus arcuicornus (15%) are dominant.
