In the site where the density was higher (Station 3809), the dominant group was harpacticoid copepods with 0.14 individuals/l.A diversity with average values (Table 6-73) was recorded at all stations, with Station 3809 showing the dominance of harpacticoid copepod (E= 0.15).The environments are characterised by the presence of a zooplankton with a low number of species and density of individuals.
