HC Deb 14 March 1990 vol 169 cc242-3W
Mr. Flynn

To ask the Minister of Agriculture, Fisheries and Food if there is any evidence of a change in the levels of disease suffered by fish or cetaceans in British coastal waters.

Mr. Curry

Disease levels in marine fish populations have been found to fluctuate from year to year and in some cases seasonally, but there is no clear evidence of a long-term trend of changing levels of disease in fish. There has been no comprehensive collection of data on the incidence of disease in cetaceans, but I understand that my right hon. Friend the Secretary of State for the Environment is considering new research projects on cetaceans and marine mammals, including post-mortem analysis for stranded cetaceans and other marine animals found on our shores.
