As for carp...
I just whack 'em and stack 'em.
(This does not mean I leave a pile of bloody fish on the bank for others to smell and trip over.)
Anybody that wantsmy carpfor any purpose is welcome to have all I can shoot.
I'll even carry them to their car.
I do have about half a dozen rotting in my garden, and I can't wait to see how well my plants do.
Other bowfishing quarry I might eat, but I'd have to find a way to make it taste good.
