Yep!!!!! Bowfin are a blast, and snakeheads are on the list!! Don't live anywhere close to a place that has snakeheads though...
As for the bowfin, I only have experience at a couple locations in NW PA, and they're all in the same watershed(French Creek watershed, which includes Conneaut, Geneva swamp, French, Woodcock Crk, etc..).
From what I learned it can be hit or miss a lot of the times, even when fishing bait. When the bite is really ON, I have no problem hooking up with 5 or more on the fly rod. But when it's slow it can be a rough day. Working relatively big, meaty, articulated streamers along the bottom and near weed lines are most productive. One thing I noticed is the more fish I see surfacing for air, the better the fishing usually is. Just an observation.
Also, make sure you have good quality hooks as there mouths are tough and keeping them on the line can be tough if you have dull hooks.
I still get skunked often but when the stars align and you hit a feeding frenzy it is a lot of fun.
