So apparently it's legal to bowfishing sharks in some states. Who's done this and who can tell me how to go about doing this?

Nobody has anything to say about bowfishing sharks?

It's illegal to shoot sharks here in Florida. I get requests for it all the time but we can't. I believe you can in Alabama. For sure in California. You have to use a large float and a strong anchoring head like the Innerloc Grapple so the head can't pull a chunk out. Gators have a bit tougher skin so we use muzzy's but on large fish and sharks it pays to have a large anchoring head! Good Luck!

bowfishing is best technique and it can be applied for big stuff and sharks also. Such type of shooting is fun target and you probably will not require any new fancy gears.

Bowfishing sharks? That's crazy. Props to those who do it, I don't think I could bring myself to get out there after them. I'll stick to hunting my land predators.

I use recurve bow to fishing

That's quite interesting!
