        If you’re a southern Taiwanese, there is no doubt that milkfish often finds its way into your rice bowl. Since the time of Cheng Cheng-Kung, this fish has played a special role in Taiwanese society.         Suh Mu Yu, as the fish is known in Chinese, is used as a major source of protein during times of economic difficulties when people can’t afford more expensive sources. Indeed, the fish is packed with goodness.        It is also low in fat and calories while being high in vitamins and minerals. While it is quite a bony fish, it is extremely juicy and full of flavor! And the countless recipes that the locals have come up with have only added to the delicious quality of the fish.It also provides a source of income for many people in the south. Milkfish farms are abundant in this area and there is even a milkfish festival held to honor this noble creature of the sea. To add to this, the She Me Yu (or　”What Fish?”), to which it is also sometimes humorously referred, also keeps the populace smart. Some people say that the reason southerners are so good at math is because of their regular eating of brain food–especially milkfish!
