In California, a survival improvement of 50 percent for chinook salmon was reported when circle hooks were used. Big-game angler Captain Ron Hamlin, who allows nothing but circles on his boat for bait or fly, has had incredible angler hookup-and-release success on sailfish and marlin. Hamlin was instrumental in launching a big-game fishing tournament that was limited to circle hooks. With new hook models available in sizes suitable for walleyes, trout or panfish, every angler owes it to the sport to give circle hooks a try. And if you're introducing someone to fishing, there's yet another reason -- circles will help a beginner catch more fish.
