Sweetfish which are known to inhabit only the cleanest rivers, can be found in the clean Seomjingang River in Hadong. That wonderful watermelon fragrance and savory flavor of raw sweetfish! Sweetfish hatch out from upper stream, travel downstream to the ocean and stay there until they are fully grown. Then, to spawn eggs, they travel back upstream to where they’re born. Sweetfish only have a lifespan of 1 year and can inhabit only the cleanest Grade I waters. Seomjingang River and Miryanggang River in Gyeongsangnam-do are considered some of the famous regions that produce high quality sweetfish.
Egg cockles grown in the clean waters along the Hallyeosudo Waterway are just filled with protein, calcium, iron and various other nutrients. They are so called the king of clams and are famous for their tenderness and sweet flavor. Their axe-shaped feet taste like chicken and make very savory, milky broth. Egg cockles taste so good because of their protein content. For 100 grams of meat, there are 21.5 grams of protein (oysters: 10.5 grams of protein) and lots of calcium (32 mg) but only 1.9 grams of fat (oysters: 2.4 grams of fat). They can be enjoyed raw but can be cooked wrapped in foil. The meat is sweet and tender when braised or fermented. In the winter, you can also braise them a little bit and dip them in some chili sauce to enjoy the sweet and savory flavor of the meat.
Ark clams are also known as blood cockles or blood clams due to the red hemoglobin liquid inside. The meat is tender and enjoyed raw, grilled or as sushi.
