Absolutely no reason to fish them. No meat, mostly bones. Usually damage the fish's mouth beyond repair. I get that it is fun to do once in your life, but you should stop now. Foul hooking them is illegal in most states too. They keep the ponds cleaner.
They actually have plenty of meat. I eat them. They are bony so they can be quite annoying to eat but taste fine. Nothing spectacular but not bad. But at the end of the day if you want something that’ll fight and isn’t a sports fish PLUS tastes good just fish for catfish
