Abstract
In the paper structure and dynamics of populations of the major six
copepodes (Centropages ponticus, Arcatia clausi, Pseudocanalus 
elongatus, Paracalanus parvus, Oithona nana and Oithona similis)  
as well as the seasonal and annual production and the P/B
coefficients are presented on the basis of the zooplancton samples
collected in 1970 and 1971 in the Romanian waters of the Black Sea, 
from above the continental platform. The gross annual production
of copepodes represented 0,8 g/m3 of wet substance. The highest
production was scored for Acartia clausi (more than 61%), followed 
by Pseudocalanus elongatus, (15,7%)and Oithona nana (10,8%). 
Paracalanus parvus and Oithona similis  scored the lowest annual
productions (2,6 and 1,6% respectively).
