Abstract
The paper is based on the results of the observations
carried out in the waters of Constanta harbour in a
fixed station between 1978-1982 and in 10 stations in
1982 (April, June, August). The structure of zooplank-
tonic communities is characterized by low specific
diversity; only a few opportunistic species-e.g.
Pleopis polyphemoides and Acartia clausi formed 
abundant populations.
