I know its an old thread but thought I would add if for nothing more than future reference...
Fishing the mangroves of Oyster creek can be very rewarding they are packed with juvenile fish that seek refuse in the mangroves and you also get better fish patrolling and feeding on these.
We also spent a good bit of time fishing off Old Denton bridge.. A right melting pot where we caught the likes of Barracuda,Sting ray and a lot of that the locals call Cheoff (if thats how it's spelt) I would have it down as a brown snapper.
There is also a galvanized pier by the African Village hotel another good shore mark.... One evening I caught what I thought was an eel...swinging it in I cleared the locals off the end of the pier as I swung it in...it turned out to be a sea snake
hanging it back over the edge The wife burnt the line with her cigarette...I thing we caught everything that could hurt ya off that pier small Sting ray, catfish with razor sharp fins and even a moray eel.
Boat fishing as you can expect does go up quite a level.... The last time we went I was connected to a Sting ray for over a hour and a half...got the leader up but still could'nt see the fish myself however the skipper and deck hand said they could see the fish.... shocking when they were on different sides of the boat...All I can say is I was releived when I went flying back as me and the fish departed.
We love the country just a shame we ain't been back for a little while now
