The main purpose of this study was to estimate the distribution, production and production/biomass ratio values of Acartia clausi, one of the most representative taxa of the Copepoda community in the Mondego estuary. The following biomass/length relationship was estimated for specimens of Acartia clausi: AFDW = 2.27 BL . Length-weight relationships were used to estimate production taking into account cohort growth and mortality. The annual production was calculated at 63.44 mgC my and the production/biomass (P/[Bbar]) ratio was estimated at 25.50. These results indicate that Acartia clausi may play a significant role in transferring energy to higher trophic levels in the Mondego estuarine system.
