| Abstract |
Two series of samples were collected with a new version of the Macer-GIROQ suprabenthic sledge, using 0.5 mm mesh size plankton nets. Chaetognaths, ctenophores and copepods (holoplankton), fish postlarvae, polychaetes and crustacean larvae (meroplankton) were sorted, counted and identified.The most abundant were copepods, the ctenophore Pleurobrachia pileus, larvae of crustaceans and the polychaete Lanice conchilega, postlarvae of clupeoids, gobiids. Three patterns of density variations were found: (1) dominance of diurnal variations, (2) dominance of tidal advections, (3) a combination of tidal advections and diurnal migrations, e.g. copepods. |
