The following biomass/length relationship was estimated for specimens of Acartia clausi: AFDW = 2.27 BL 2.41. Length-weight relationships were used to estimate production taking into account cohort growth and mortality. The annual production was calculated at 63.44 mgC m−3y−1 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.engAcartia clausiBiometryImage analysisProduction zooplanktonEstuariesjournal article
