Abstract 
Based on the high amount of zooplankton collected over several years 
in the Black Sea water facing the Romanian littoral, at low depths, 
the author analysed the results of researches on certain biological 
aspects of the major Copepodae living there, namely: Acartia clausi, 
Giesbr., Pseudocalanus elongatum, Boeck, Centropages ponticus, 
caravaj. and Oithona nana, Giesbr. The paper also analyses the repro-
duction rate and intensity, age structure of the population, sex 
ratio and Copepodae distribution in cross section, in keeping with 
the specific environment conditions, with season (spring and summer),
and with Copepodae consumtion by various other organisms.
