I guess I'll chime in......hesitantly...
I am a commercial lobster/ marine life diver. I don't live in the keys, and have never seen a "castilla". I work hard for my money, and collect fish/lobster in an ethical manner. I don't see a problem with that. There are 1.4 million trap tags out there, scattered all over the seagrasses and reefs, you tell me who's doing the damage.
As for treating our fisheries like the Bahamas, if that means locals do whatever they want, fish trapping still exists, permits for Korean fishing boats issued, and hardly enforcing the few laws they have........you gotta be crazy. The only reason they have alot of fish over there is that they have thousands of square miles of reef compared to our strip of reef from shore out a few miles here on the east coast.
Why are our lobster numbers dwindling......is it because commercial divers take 'em from structures....or because mini-season wipes them out.....or beacuse trappers don't have a limit???? No, It's because all of our lobster come from lavea in florida bay and similar sanctuaries, and those larvea came form feeder reefs throughout the gulf of mexico, central and south America, and all of the Carribean. Lobster spend the first year of life floating around in the currents. Our shortage of bugs is a direct result of the lack of protection in other countries....unfortunately, there is little we can do about it except watch the divers in Belize and Ecuador deplete their own, and our lobster stocks.
Hope my rant shed some light for some of you.
