History

Coastal and river fishing for bluefin and related species supplied essential protein long before agriculture spread globally.

Salting, drying, smoking, and fermenting extended the shelf life of bluefin and enabled long-distance trade.

Ice preservation and railway transport brought fresh bluefin to inland cities beyond fishing ports.

Industrial freezing, aquaculture, and global logistics made bluefin widely available in international markets.
