Korea's tuna exports have flatlined in March due to the La Niña phenomenon, which has disrupted tuna fisheries in the central and western Pacific. The phenomenon is expected to continue until June, causing sluggish catch and reducing tuna production. Additionally, high international oil prices and unstable container supply/demand are negatively impacting tuna exports. Fuel oil, which accounts for about 30% of the direct cost of tuna fishing vessels, is a significant cost factor. KMI anticipates these challenges to persist in the second quarter of 2022.
