Surveys of demersal fish and epibenthos in the Tyne, Wear and Tees estuaries, begun in 1981 as part of a wider sampling programme to assess the effects of pollution and its reduction by various control measures, are discussed. Available survey methods are reviewed and the development of a survey protocol is described. A preliminary assessment of the data identified differences between the estuaries and the distribution of major species in the Tyne, and provides evidence of long‐term water quality improvements.
