Abundance and structure of copepod communities along the Atlantic coast of southern Morocco
Zooplankton composition and the spatial and temporal abundance distribution of copepods were examined on the southern Atlantic coast of Morocco. In 1998, 31 stations during March and 30 stations during July were sampled on the continent shelf between Cape Blanc (21° O’N) and Cape Boujdor (26°30’N)....
