Korea's blue crab auction price jumps 92.5% as West Sea catch shrinks
Korea's autumn kkotge season has turned into a seller's market. Male blue swimming crab at the Noryangjin wholesale market averaged 20,400 won per kilogram in the third week of October, close to double what the same grade fetched a year earlier, after the West Sea fleet landed far fewer crabs than the season promised. For anyone selling frozen crab or crab-based products into Korea, that gap is the clearest pricing signal of the quarter.
The Numbers
The benchmark comes from the Noryangjin Fisheries Cooperative's weekly seafood report for 12-17 October, reported by Chosun Ilbo. Male crab cleared at 20,400 won per kilogram, up 92.5% on the same week of 2025 and 27.5% higher than the week before.
Volume explains the move, not demand. The National Institute of Fisheries Science expects the West Sea autumn catch to finish between 12,000 and 16,000 tonnes this season, or 69-92% of last year's total. The institute blames a weaker Yellow Sea bottom cold-water mass: without that cold pool concentrating the stock, the grounds have scattered across the West Sea and catch per net has fallen.
Retail has already repriced. When the summer ban lifted in late August, E-Mart and Coupang both opened at 689 won per 100 grams. E-Mart's shelf price for domestic autumn crab now sits near 1,500 won per 100 grams outside promotions, roughly 2.2 times the opening price of the same season.
The same report shows how uneven the Korean autumn basket has become. Hairtail averaged 14,900 won per kilogram, up 119.1% year on year. Shucked oysters reached 12,400 won per kilogram, up 30.5%. Mackerel went the other way at 2,800 won per kilogram, down 17.7%, on an expected 10% increase in landings against the five-year average.
What It Means for Buyers
A 92.5% jump at auction is not a blip that importers can wait out. Korean distributors buy crab against a short autumn window, and when domestic supply misses by a third, the shortfall is filled from frozen inventory and imports rather than from next week's boats. Expect Korean buyers to lean harder on frozen whole crab and cut crab through the fourth quarter, and expect them to negotiate against a domestic reference price that is now nearly double last year's.
The second-order effect matters more for processors. Crab meat at these levels pushes Korean and Japanese manufacturers toward surimi-based alternatives, where the cost per kilogram of protein is far more stable. Crab stick demand tends to firm in exactly this pattern: fresh crab gets expensive, retail buyers trade down inside the same category, and the surimi line absorbs the volume. That shift usually shows up in orders four to eight weeks after the auction spike, not immediately.
Treat this as a read on the market rather than a forecast. Crab stocks can recover quickly when a cold pool reforms, and the institute has said the standing stock itself has not collapsed, only dispersed.
What to Watch
The Noryangjin weekly report through November, to see whether the 27.5% week-on-week gain holds or reverses as late-season landings arrive.
Whether the fisheries science institute revises its 12,000-16,000 tonne forecast, which would reset expectations for the spring season.
Korean retail shelf prices per 100 grams at E-Mart and Coupang, the fastest public read on whether the wholesale spike is reaching consumers.
Surimi and crab stick order enquiries from Korean and Japanese processors, the leading indicator for substitution demand.
