"Seldom will you see Chilean sea bass claiming the most elaborate sauce on the carte du jour. That spot is now reserved for the new fish of the moment - branzino, orata, tilapia. But there is a critical difference between these fish and the toothfish that your waiter will not likely reveal. All of them are grown on fish farms. Seafood importers I spoke with say that an ever-increasing percentage of the fish they deal in are aquacultured. As we reach the end of the big natural predators, farmed fish will replace wild, just as beef cattle replaced buffalo."
