Adi, Have fun, about 10 years ago I was down there and went out with some of the local rasta fisherman, they dove for conch and I think we used that for bait, not to mention a delicous conch soup, we caught a mixed bag of fish, I can't remember what (my memories of the trip are kinda of hazy for some reason
) , but we cooked up a nice feast later that night. Definitely talk to the locals, they are some of the friendlist people in the world and they will be glad to show you around and help you out.
