Abstract
On the basis of 276 samples collected during the years 1973, 1974 and
1976 from the marine area in front of the Danube Delta, the features
of zooplankton populations are presented in the paper. In the last
years an increase of the density and biomass of some important
zooplanktonic groups (meroplankton and Cladocera) has been recorded.
Consequently, the trophic potential of the Romanian predeltaic area
is high.
