We don't eat fish from around Vieques of any type. We have had friends from three different boats get ciguatera round Vieques, even on passage well offshore. No barracuda from south side of St. Thomas per our Frenchie fisherman friend. We don't eat barracuda north of Guadeloupe and do not eat the baracuda we catch. We do eat snapper, grouper, blue runner/hardnose, and pelagic fish. Local fisherman are our best source of info on ciguatera.
Ciguatera nervous system symptoms are terrible, debilitating, and long lasting. It is worth avoiding.
