Abstract
    Reduction in pollution load to Iddefjord has lead to a more diverse community on the sublittoral rocky bottom at two sites at 7 and 17 m depth from 1978 to 1980. The changes were confirmed by fixed-site stereophotography. The sites were initially dominated by a single species, Polydora ciliata, which was then partially replaced by several other species, particularly Mytilus edulis and Ciona intestinalis. It is suggested that improved water quality indirectly effected predation and natural succession.
