Market Overview: The Korean mackerel market in 2024–2025 is shaped by both challenges and opportunities. Consumption fell to a record low of 66,000 MT in 2024 due to reduced domestic catches and lower Pacific mackerel imports. Despite this, Norway remains the dominant supplier, accounting for nearly 68% of the market and 88% of import share, supported by consistent size and quality. Domestic mackerel, by contrast, is increasingly small in size and often exported, leaving limited supply for local use and pushing wholesale prices 37% above imported fish. In retail, Norwegian mackerel leads in frozen and boneless categories, while salted mackerel continues to decline as consumers seek healthier, more convenient formats. E-commerce now represents 28% of sales, particularly strong in frozen fillets and ready-to-eat products, driven by younger households and small families. Looking ahead, rising prices and competition from meat remain hurdles, but Norwegian mackerel is well positioned to maintain leadership thanks to its reputation for quality and stable supply.
