Seafood by season — a south-coast calendar

On this coast the menu is written by the water, and it changes with the season the way inland menus change with the harvest. The same market lane serves anchovies in spring, pike eel in high summer, gizzard shad when the wind turns, and oysters through the cold months.

This is a calendar, not a checklist — eat whatever the season you arrive in does best. Each entry links to the full local lists for the areas that do it best; as always, no single restaurant is named and nothing is ranked.

Spring — anchovies and the first greens

Spring belongs to the anchovy. Gijang, on Busan's northeastern coast, is its home water: when the boats come in, the fish are shaken from the nets in silver sheets, and the season is eaten fresh — as anchovy sashimi, which never travels far from the ports, or simmered into stews.

In Tongyeong, spring means dodari-ssukguk, a clear soup of flounder and young mugwort that lasts only as long as the herb does. It is the region's short-lived signature dish — locals plan trips around it, which tells you what you need to know.

Summer — eel on the fire

High summer is eel weather. The southern harbours of Gyeongnam — Goseong and Tongyeong above all — are known for hamo, pike eel, sliced fine and swished through hot broth at the table; the flesh blooms open as it cooks, and it is treated as a restorative dish for the hottest weeks.

Grilled eel does the same work in Busan, and stamina food generally peaks with the heat. If the beach crowd is not your scene, this is the season to head down the coast for a harbour lunch instead.

Autumn — the gizzard shad returns

When the heat breaks, jeoneo — gizzard shad — comes into its own; the Korean saying claims the smell of it grilling will bring home a runaway daughter-in-law. It is eaten both raw and grilled whole, and the southern ports celebrate its return through the early autumn.

This is also the coast's most comfortable eating weather — market lanes without the summer crush, mild evenings on the harbours. Autumn is half the argument for visiting in October.

Winter — oysters and cod

Winter is the coast's quiet feast. Tongyeong is Korea's oyster capital, and the cold months are their season — raw, steamed, fried or in soup, they are everywhere and inexpensive. The same waters send up mulmegi, a soft-fleshed fish whose clear winter stew is a local institution.

In the sheltered bay off Geoje, winter cod return to spawn, and the harbour towns cook them into a clear soup that locals hold above almost everything else in the season. Cold-weather travel here eats better than most summer trips.
