I only got to fish for them after moving here from the Keys.
There aren't any down there that I'm aware of, at least where i lived.
I used sand fleas and shrimp here in the I/R, but especially the fleas, come off very easily.
Thought about cut squid strips, they stay on well and would hold up better on casting.
Actually considering that for catfish also, for sure they work on the salt water versions.
