“ The Castle Loch is the only fresh water in Scotland, and possibly in the British Isles, where the vendace (coregonus vandesius) occurs. This fish, which is believed to be growing scarcer, is alleged on doubtful authority to have been introduced by Queen Mary. It is captured by the sweep-net in August, and is esteemed as a delicacy. The lakes adjoining the town afford the inhabitants exceptional advantages for the game of curling. ”
