Izzy- nothing wrong with using a longbow for bowfishing, have done it many times. The longbow does need a little more arrow tuning. the recurve of course as we all know is center shot and are beloved longbows for the most part aren't. The trick I learned the hard way, is to take your time and shoot the arrow out of the bow, and trim it! Like everything else we are trying to get the arrow flying straight in the water. Hint, paper tune your bowfishing arrow at home to hit a perfect bullet hole, this will take some time. All your fish points have barb's, duh. I weigh the point and get a field point the same weight, hot melt it on, then trim the arrow as needed. another thing, if you are bowfishing from a boat, ensure the knee rail is low enough for the bottom limb to clear it (learned this the hard way, ha-ha). The reel Orion said will work, but I find that the great northern strap on adapter is great and can switch from one bow the another with no problem. When you bowfish you typically shoot alot, so ensure you have a low poundage bow, hell, I have shot 40# fish with a 35# bow with no problem.
