C from UK... I think you could fish from there, but don't know how much you would catch. It's true what's been said here, that close in to shore it's filled w/turtle grass and very shallow. There's some decent snorkeling to be found under the piers, esp at night, but you have to be patient, it's the small stuff that comes out.
We didn't see any fishing from the piers, so I guess if the locals don't, you won't have much luck. Am sure you could ask the neighbors, they're fishermen and would know where you could fish from the shore.
If you have any other questions, feel free to email me!
