p. 295 - 312 DYNAMIQUE SPATIO-TEMPORELLE DE LA COMMUNAUTE ZOOPLANCTONIQUE DU LITTORAL ROUMAIN DE LA MER NOIRE Elena-Ecaterina Dinu Institut Roumain de Recherches Marines Constanta Abstract On the basis of 147 samples collected between 1986 and 1987 the author presents the evolution of the qualitative- quantitative structure of the zooplankton from the Romanian inshore waters. The biomass of zooplankton oscillated between 16 mg.m-3 (spring) and 27,000 mg.m-3 (summer) with an average value of 7,220 mg.m-3. The feasible production of "trophic" zooplankton was estimated at 21 millions tons of wet organic substances.
