RE: Archery Fishing??
Actually, i think you can shoot mud cats. As for channels and blues im not sure.
Start with a kit. Drum reels work best i think, unless you wanna spend more money. Try to get arrows that have steel leaders on them, or put leaders on your arrows. Look for shallow water with good access from the bank. Normally below lake dams or near spillways is good. If youve got a boat, go to shallow coves in lakes and cruise slowly and quietly. Other than that, hold on.
Also, dont tie the line to your reel or bow! Leave it loose so if the fish takes all the line(and hes really big) he wont take your bow with him. I know a buddies bow is at the bottom of the ocean after shooting a 300 pound grouper.
