This paper briefly reviews the environmental impact of the cage culture of salmonids in fresh waters, and evaluates the effects of this fish farming practice on the growth, behaviour and diseases of inland fish populations, concentrating on relationships between rainbow trout cage culture and indigenous brown trout populations. Possible future developments in salmonid cage culture are also discussed and the implications of this development for inland fisheries evaluated. The paper argues that the development of models should enable improved prediction of eutrophication from cage culture, to the benefit of the fish farmer, inland fisheries and other freshwater users, but also identifies a clear need for research in other areas of possible conflict.
