Freshwater Marsh Clam: A Treasure of the Bountiful Ecosystem of Seomjingang River

When & Where

The peak season for freshwater marsh clam is from March, when flowers begin to bloom, until June, before the rainy season starts.

Hadong in Gyeongsangnam-do is located at the mouth of the Seomjingang River and is known as an ideal area for cultivating freshwater marsh clam. The region boasts optimal conditions for these clams, which require a suitable mix of freshwater and seawater to thrive. Many specialty restaurants serving freshwater marsh clam can be found around the Hwagae Market area and along Gyeongseo Road near the Songrim Roundabout in Hadong.

One commonly used expression among Koreans is “siwonhada,” meaning “cool” or “refreshing.” This is rather difficult to understand for non-Korean speakers as Koreans use this expression to describe piping hot soup, essentially describing it as being “cool” or “cooling.” When Koreans describe something hot as “siwonhada,” it conveys a feeling rather than a physical temperature—specifically, the sensation of relief or comfort that comes from consuming the food, like a hangover being relieved with the hot soup.

This expression is frequently used in relation to Korean soup dishes, especially when enjoying haejangguk (hangover soup) as a remedy for hangovers. To break down alcohol, the human body requires energy and water. Haejangguk ingredients, such as bean sprouts, seonji (blood pudding), and dried pollack, are all high in protein. Eating haejangguk replenishes energy through protein and carbohydrates while the soup’s liquid content adds hydration, leading to that satisfying feeling of relief, prompting the spontaneous use of the word “siwonhada.”

Freshwater Marsh Clam: A Symbol of Abundance of the Estuary

Shellfish are among the ingredients that can evoke the expression “siwonhada.” One type of clam, in particular, is especially so and that is the freshwater marsh clam. Freshwater marsh clam thrives in brackish waters where rivers meet the sea. The ideal habitat of freshwater marsh clam is at the mouth of the river, where sand begins to accumulate. This is precisely the case for the lower reaches of the Seomjingang River.
The Seomjingang River originates in Jinan and Jangsu in North Jeolla Province and flows toward Gwangyang, winding around Jirisan Mountain into South Jeolla Province. The absence of a tidal dam allows for the development of brackish waters in the lower region, and the sedimentary terrain creates a favorable environment for freshwater marsh clam.

The people of Gurye, Hadong, and Gwangyang, which are located around the mouth of the river, pick freshwater marsh clam from spring to early summer each year. The river is only about 1 m in depth, so people can step into it and rake the riverbed to harvest the freshwater marsh clam. Boats are sometimes used to harvest them in deeper areas.

How to Cook Freshwater Marsh Clam

The easiest way to enjoy freshwater marsh clam is jaecheopguk (freshwater marsh clam soup). Start by placing the freshwater marsh clams and water in a pot and boiling them. Once the freshwater marsh clams are cooked, remove the shells and separate the meat. Be sure to save the water used for boiling the freshwater marsh clams; do not discard it.

Next, transfer the reserved boiling water into a earthenware pot and bring it to a boil. Prepare some chopped buchu (Korean chives), which have a mild flavor and are rich in minerals. Boil the soup, then top the soup with chopped buchu and the freshwater marsh clam meat to complete the jaecheop-guk.

You can also transform the finished jaecheopguk into a hearty meal by adding rice, making jaecheop gukbap (freshwater marsh clam and rice soup), or adding noodles for jaecheop guksu (noodle soup with freshwater marsh clam). Once you have the soup in front of you, take a spoon and taste the soup first. You will see why Koreans describe this soup as “siwonhada.”

The freshwater marsh clam meat can also be used to make jeon (pan-fried battered dish). When mixed with buchu, jaecheopjeon becomes a savory dish that tantalizes the taste buds. Freshwater marsh clam is often served as sashimi, typically prepared as jaecheop hoemuchim (spicy raw clam salad). Placing this spicy clam salad over warm rice makes for a delightful side dish. In restaurants, you might also be provided with a bowl for bibimbap, allowing you to mix it with rice as you eat.
