The Harley Shakes is a fly created by Stuart Hartley, a guide for Tourettes Fishing, designed specifically for the Tiger Fish (Hydrocynus Tanzaniae) of the Mnyera and Ruhudji Rivers in Tanzania. It’s a surface fly that is very productive and a favourite for these rivers. You can see the fly in action in The African Tiger filmed on these two rivers.
Here’s a video Stuart shared with us tying the Harley Shakes.
