I have purchased fish from the Marigot Market for years. The people there will assist you in how to prepare, what the fish is. Get there early because the resto's buy up all the good stuff. We have purchased mahi, snapper, trigger fish, even sardines and of course lobster...some we loved...some not so much. When we can't get to the market, we go to skipjacks market for good fresh fish to cook at home.
