Well, it's not March yet, so maybe this will help:

It's been 26 years since I was there, so take this with a grain of salt. While I didn't fish, I did four dives over two days from the island. There were plenty of reef fish to be seen not all that far from shore. Easy to rent a kayak, paddle out and have at it. As well, while snorkeling by the rocky edges at the end of beaches, I observed a lot of fish. Trophy tarpon, nah. But enough numbers and of a size that I was wishing I'd brought a rod/reel and a small selection of lures. Think bass gear, not Pike or Musky.
