1960-1970 Barnes, RSK and Coughlan, J Blackwater Estuary Bottom Fauna Dredge Survey

A number of additions and corrections are made to the Blackwater Estuary fauna list. Distribution patterns revealed by a survey of the benthic fauna of the Blackwater Estuary in May 1970 are described, and changes in the frequency of occurrence of a number of species between 1960 and 1970 are discussed. It is concluded that the fauna of the region has, to a large extent, recovered from the severe winters of 1961-62 and 1962-63.
