Oliver McGilloway presents in this documentary about fish and provides information on the rivers that Trout would live in.
Beginning at a mountain stream in North West Donegal, the viewer gets an explanations on the how the colour of the water indicates where it is coming from and the kind of trout you could expect to find here. An issue of the location is the acidity of the water which effects plant life and therefore also effects the trout's food source.
