Stockfish Preservation Technology

Timeline

1. c. 900–1100Norwegian coast · NorwayNordic fishermen in cold, dry seasons gutted and beheaded cod and hung them on racks to air-dry, using low temperatures and sea winds to dehydrate and inhibit bacteria, producing stockfish for local consumption and long-voyage provisioning.
2. c. 1100–1300Bergen · VestlandFrom the 12th century, stockfish from places like Lofoten was exported through Bergen, where German merchants established trading posts, incorporating the dried cod into the Hanseatic trade network in exchange for salt, metal goods, and cloth.
3. 1311–1320Lofoten Islands · NorwayBetween 1311 and 1320, the winter Lofoten cod fishery and spring drying process produced large quantities of stockfish, shipped by Hanseatic merchant vessels from Bergen to Lübeck and Central Europe, becoming an important protein source during Lent and in grain-short regions.
4. c. 1500Lofoten Islands · NorwayAfter the Hanseatic decline, Norway continued the traditional drying process; since the 19th century mechanized processing and cold-chain logistics were introduced, but the core principle—natural cold-climate air drying—remains the basis of Norwegian stockfish exports.
