HC Deb 03 December 1986 vol 106 c681W
Mr. Chris Smith

asked the Secretary of State for the Environment what research Her Majesty's Government have commissioned or completed in the last three years to determine why coastal dolphins and porpoises are disappearing from the southern part of the North sea.

Mr. Waldegrave

No such research has been commissioned. There is no clear evidence of these populations declining, but the Sea Mammals Research Unit is collating relevant available material in readiness for next year's London conference on the North sea.
