The nice thing about bowfishing is any old bow will work, and the older the better. You wouldn't want your good hunting bow covered in blood and slime. 55# compound will work, but might be too much - you don't want the wholearrow to go all the way through the fish. You also want a longer ATA length to avoid finger pinch. I personally prefer and use some cheapy recurves I got off eBay. I had started with an old compound, but it weighed a ton. There are also bows made specifically for bowfishing, but I found it easier to spend $20 on a bow instead of $200, and it shoots fish just as well.
