Famous for its unique taste, gizzard shads are a type of Herring delicacy in Korea best enjoyed in the fall. Hongwonhang Port in Seocheon (Chungcheongnam-do) hosts the Jeoneo (gizzard shad) Festival every October for visitors to enjoy a fresh catch of this fish served up in a variety of ways. A number of popular dishes range from roasted to sashimi-sliced Jeoneo and even salads mixed with spicy marinated Jeoneo, cucumbers, sesame leaves, and parsley.

The festival opens with exciting performances and a food-tasting event and ends with a spectacular evening fireworks show. Visitors can also taste a variety of other local dishes made with salted eel, dried seaweed, crab, and shrimp. Fresh produce and seafood will also be available for sale in the various shops and stands. Additional exciting events include contests for fish-catching, shell-gathering, fishing, and singing.
