Whilst the fish populations of the majority of Highland lochs are dominated by trout of 8oz or less, they are usually free-taking. Such lochs can provide children with an ideal introduction to angling. There are also a great many lochs where the feeding is better and the average weight is considerably more, with the occasional trophy fish between 2lb and 6lb (sometimes even heavier). This class of loch includes some that are not typically Highland in character including the fertile low-lying waters of Orkney and parts of Caithness and the limestone lochs of Durness.
The deeper lochs of the Highlands and Islands usually contain small populations of ferox trout, a strain of slow-growing heavy brown trout often with cannibalistic tendencies, which can grow to great weights (up to 20lb or more).
These are most prevalent where there are healthy numbers of char and their capture requires the use of highly specialised tactics such as lures trolled at considerable depths.
