Estimates of high absolute densities and emergence rates of demersal zooplankton from the Agatti Atoll, laccadives

Abstract

Direct sampling of the sandy substratus of the Agatti Lagoon with a corer showed the presence of vary high densities of epibenthic forms. On average, densities were about 25 times higher than previously estimated with emergence traps. About 80% of the organisms migrated into the water column within an hour after sunset, an maximal resettlement occurred soon after dawn.
