DAILY VERTICAL MIGRATIONS OF CALANOIDES-C ARINATUS AND METRIDIA-LUCENS (COPEPODA, CALANOIDA) IN THE NORTHERN BENGUELA UPWELLING AREA

The daily dynamics of the two most important dominant zooplankton spec ies Calanoides carinatus and Metridia lucens were investigated from th e surface to the bottom (0-450 m) in the northern part of the Benguela upwelling area. For both species distinct age-and sex-specific differ ences in patterns of migrations were discovered. Various zonation and maintenance of copepods populations as a result of interaction of migr atory behavior of different stages of the both species with alongshore currents regimes and cross-shelf processes are discussed.
