New species of Brown Trout found in Loch Laidon

According to 'The National ', newspaper on Saturday, the discovery of a 'distinct' species of brown trout in Perthshire may signal the 'tip of a biodiversity iceberg', in Scottish waters,according to scientists at the University of the Highlands and Islands (UHI). The species known as 'profundal benthivore' has not been seen in any other loch,

in the native range of brown trout, and its discovery suggests we have a lot more to learn about Scotlands freshwater biodiversity. This specific fish is a bottom feeder, living in the  loch's where very little light penetrates, the deepest parts, and feeds on organisms on the loch's floor. The researchers, led by Professor Eric Verspoor, used DNA analysis to identify different genetic trout populations. This is essentially a distinct species of brown trout, never before reported, and the total number of forms found in Loch Laidon, is the highest number so far found in a single lake. The profundal benthivore, has bigger eyes, and a larger mouth, than other brown trout, and is distinguishable from other species due to its lighter skin. The research on Loch Laidon's trout, was published in was published in the journal of Freshwater Biology.
