Coloured maps of Loch Lomond have been produced by the Loch Lomond Angling Improvement Association.
"This map is the only colour angling map ever likely to be needed for those who fish Loch Lomond either for game or coarse species," the blurb on their website says.
"The Coarse section was done by well-known pike experts with input from other leading experts in coarse fish. All the well-known hot spots for pike and other less known parts that produce great pike are all listed."
