The lake my dad and I escape to every summer for our Canada fishing trip is a muskie/pike sanctuary near Sioux Lookout, Ontario. In addition to being a catch-and-release only lake -- which we would do anyway -- it is a single hook, no barb, no livebait lake.
This means you can only use baits with 1 hook (or 1 treble hook). If you have a crankbait with 2 sets of trebles, for example, you'd need to remove one of the treble hooks. And, of course, pinch off all the barbs.
The lake is teeming with big pike and muskies that we see and catch year after year. But it's never fun to lose a big muskie at the boat that maybe - just maybe - you would have caught with another treble hook or barbs.
What do you think about barbless hooks?
