The prized species that shares the dory name is the John Dory (Zeus faber), but only a small volume of this excellent and expensive fish is available in the United States. Two related species from New Zealand, black and smooth oreo dories, are more common to the U.S. market. Though they look a lot like the John Dory and have similar lean, white, flesh, they are not true dories but members of the family Oreosomatidae. The black oreo dory has rough, black skin. The brown skin of the smooth oreo dory is as its name indicates. The smooth oreo is more highly regarded than the black, since it offers larger, whiter fillets. Market size for both oreos ranges from 1 to 2 pounds. The oreos are trawl-caught, both as targeted species and sometimes as a bycatch of the orange roughy fishery. Because they are harvested far offshore, oreos are almost always marketed frozen.
