Do I need a permit to fish the Doubs?

What flies work best on the Doubs?

Small patterns are essential—typically sizes 16-22. For dries, CDC patterns, Comparaduns, and sedges work well. Nymphs should include Pheasant Tails and small flashback patterns. French nymphing techniques are particularly effective.
