Abstract: The intertidal sediment macrofauna of Dublin Bay was sampled over a total of 313 sites throughout the bay. The most conspicuous organisms were Nephthys caeca, Nephthys hombergi, Scoloplos armiger, Cerastoderma edule and Tellina tenuis, and in general, the fauna reflected the domination of the Bay by the sand habitats on the North and South Bulls. The standing stock of the Bay was dominated by the bivalves, which contributed over 80% of the biomass, and these in turn owed their supremacy largely to C. edule which accounted for over 80% of bivalve biomass. The bivalves were good indicators of the biotopes in the Bay: an outer sandy zone characterised by T. tenuis, and inner sand/mud zone with C. edule and Macoma balthica and muddy lagoons characterised by Scrobicularia plana and occasionally beds of Mytilus edulis. Bivalaves were absent from the inner Tolka basin where Nereis sp. predominated. Shannon-Weiner Index values for the Bay as a whole were good and there was little wide-spread indication of pollution damage.
