Circle Hooks for Trout?

Bluewater anglers have realized the benefits of circle hooks by way of reduced fish mortality for years now.  The new Moffitt Angling System is an exciting flyfishing innovation developed specifically to also reduce trout (and other species) mortality when
catch-and-release fishing. Unlike traditional flies tied on J-style hooks, Moffitt flies are hookless and suspended on the leader above a uniquely designed and rigged circle hook.
Virtually all fish caught with the Moffitt System are hooked in the jaw — and accidental deep hooking, gill hooking and foul hooking are all but eliminated. Because the circle hook is barbless, most fish can be released without removing them from the water.  See moffittangling.com for details.
