Tate, don't know if you've been, but there just AIN'T a lot of cows in the Bahamas. A glass of milk can set you back and most of the butter I found comes from Denmark, you dig? By day three we were eating Bahamian breakfasts; fish chowders, conch stews, that sort of thing, because pancakes with butter and syrup required a loan (okay, I'm exaggerating because I'm a cheap swamp Yankee and the wife is even worse, but hey...when in Rome, I always say...)
BG, fish is what you got, so work with it. Good bacterial food AND good fungal food; that's a really short list of things that are both. And you can get worms shipped, my friend... maybe be the first guy on a block with a cow? you can clean up on the milk

Now how to get the cow to eat palmetto and agave? How about
Pinus caribaea?
