All I could find in the regs, under storing and transporting fish, seemed to be in reference to fish holding structures made with man-made materials. That's were the name and address thing comes into play.
 I've seen plenty of rock fish wells, but I thought "we" had a conversation about them, and I'm thinking the thought they were "illegal" had to do with fish mortality rates from predators or fish that get out but have been affected by heat or possibly low oxygen rates?
 It might just be faulty memory on my part :-/
