YP are probably quicker to swallow the hook than any other fish I'm aware of.
My Dad and I think YP is the best eating of all, so we keep a five gallon bucket handy. If we take out a hook on a questionable fish he goes in the bucket. You'll know generally in 15 minutes if the fish has any chance of survival, i.e., he's still swimming in the bucket.
YP tolerate low O2 extremely well, in particular if the water isn't too hot, so if a "to be released" fish spends some time in a five gallon bucket with two gallons of water they're not the worse for wear.
It they start floating or struggling, it's straight to the frying pan.
Holding a redear sunfish is like running with scissors.
