Core insight: At the start of 2026, Norway's mid-to-high-end fish market presents a "world of difference": on one hand, due to a high landing volume, herring exports increase, causing prices to drop; on the other hand, Norwegian mackerel exports plummet sharply, but prices return to high levels. The core variable behind this contrast is not demand, but rather the direct impact of quota cuts and policy changes on the raw material side.
