I don't know enough about the shrimp farming/hatchery business to give a good answer. Why did the Nova Shrimp people dynamite the quarry behind the hatchery that is at the site now?
Fidel would probably know hes been in that business up there for a lot of years.
Lots of fresh water is involved in shrimp raising and their going to strike that fairly quick when they dynamite the quarry. the new quarry is next to the one Nova made for the shrimp hatchery.
The shrimp business is at that location because of the locations natural offerings (prob.water and cheap land). The materials coming out of the hole are not the objective. I wouldn't say they are worthless just not the motive.
You guys probably haven't been around long enough to remember the problems and concerns of what the shrimp farm has done up there.
READ THIS OLD REPORT
and see if this whole thing makes sense.http://ambergriscaye.com/pages/town/eventsnova.html
maybe Fidel is banking on the islands short term memory loss problems and now hes chairman of the Ambergris Caye Planning committee that stopped him last time.
God I love this place :-)
