If you are a commercial hook and line fisherman, you cant fish in a RCA. But seine and gillnet can. The rational is that rockfish are bottom dwellers and anyone stupid enough to drop his $10,000 seine net or his gillnet into the bottom for the sake of a few salmon is going to learn quickly that its not a good thing!! LOL
Realistically. the RCA is there to help out rockfish..... not to prevent all types of fishing that probably will not hurt rockfish one iota.
