80 % survival.
i cant actually speak on the bait caught side because i'm pretty well 100% s/plastics.
only having a shallow sided 12 foot boat i try to unhook and release undersize fish without netting or bringing onboard except where the need for longnose pliers to get hold of the jighead.
the ones you dont handle much scurry away like there is no tomorrow but the ones that have to be seriously unhooked and i dont mean gut hooked either are pretty groggy from just a minute of handling.
they are one of the softest fish i think so far as handling goes.
being catch and release off a breakwall i'd be surprised if even 50 % .
