Snagging paddlefish is about the only way you catch them. I occasionally go out and snag grass carp. (I usually try and flyfish for them when the mullberries are dropping) and that can be a blast. As far as hitting vital organs with grass carp it is sight fishing and you only get flesh 99.9% of the time. I once read an article in field and stream about snagging paddlefish and it looked like an absolute blast. Don't think I would ever eat one though.
