HC Deb 19 June 1961 vol 642 cc92-3W
70. Mr. Prior

asked the Secretary of State for Scotland what report he has had from his fisheries research department on the appearance of hump-backed salmon off the north-east coast of Scotland.

Mr. Maclay

In July last year a humpbacked, or pink, salmon was caught in a bag net near Aberdeen, and I am informed that one was caught by rod and line in the Derwent at Workington, Cumberland the following month. Unconfirmed reports have also been received of the capture of four others in Scottish waters. My scientists report that the appearance of these fish in our waters is probably the result of the transfer in recent years of large numbers of Pacific salmon eggs, chiefly pink salmon, to the rivers of the Kola Peninsula of Northern Russia, which flow into the North East Atlantic.
