Here is a link to a very good article by Dr Martin Jaffa which has appeared in the Scottish edition of ‘The Times’ today (Tuesday 15th December 2015). It follows a recent press release by Salmon & Trout Conservation Scotland blaming sea lice from fish farms for the decline in salmon and trout in rivers in the ‘aquaculture zone’ of the west coast of Scotland. Dr Jaffa eloquently points out that the decline of salmon and trout on the east coast of Scotland, where there are no fish farms, is measurably greater and suggests that all salmon and trout returning to Scottish rivers to spawn should be protected. This article has not appeared in the English edition, but is highly recommended.
