| Summary: | Non-salmonid "coarse" fish are widespread and abundant in Scotland(e.g. Maitland & Campbell 1992) but little scientific research has beendone on them, compared with the extensive work on the Atlantic salmon(Salmo salar) and populations of brown and sea trout (Salmo trutta).Nevertheless, coarse fishes interact with salmonids and there is growingconcern that unwanted introductions, such as ruffe (Gymnocephaluscernuus) in Loch Lomond (see below), are threatening the native fishfauna of Scotland. Some major points about the ecological role of coarsefish in Scotland were made by J.W.T. in a brief article published inFreshwater Forum, Vol. 3, No. 1, pp. 20-25, (Coarse fish in Scotland: athreat or a resource?). Here we provide a more extensive annotatedbibliography to a full list of species occurring in Scotland, to highlightwhat is known about them and to indicate potential areas for furtherresearch.
