I am sorry I didn't get this posted a while ago so it could have at least been presented. hopefully it can still be propsed as a future alternative.

I don't kow anything abut the area but I can say this. Go to the meetings, email the people involved and make your voice heard. I have been part of the process for a long time now and my voice has been heard many times. One a couple occassions I was the only one who made a comment or proposal and it made a huge difference. My opinions and observations made those who were considering the changes to think about the topic and they did or didn't make the changes because of it.

One voice of reason and thought out deductions can be just as if not more powerful than an army of people with nothing but gripes.

If they need a refuge for divers let the divers make one. Take a small section, place habitat there in the form of reef balls and other artficial reefs and leave it at that. The divers get their haven, the fish have better habitat to replace dwindling stocks and fisherman don't lose but a small place instead of an entire region. Don't take away good fishing spots just for diving, make new ones in places where fishing needs a habitat boost and everyone wins.

If they need to get educated on reef balls, here is the site.
