Haven't bowfished in years... been stationed/living in the arid, desert parts of the southwest mostly.
Did it often when I lived in MI. Used a Bear Grizzly w tape on reel and 90lb test, std solid glass arrow w harpoon point.
After spring floods water would recede and fish would get trapped in pools. Talk about shootin' fishin a barrell... could often get 3 or more on one shot!
One time shot at a fin sticking up out of some muddy, shallow water... hit a BIG "alligator gar" that pulled me right outta the canoe! OK, wasn't that hard since I was about 4'11" and @ 90 lbs at the time...
