Fish
Bluefin
Bluefin tuna (Thunnus thynnus and Pacific/southern relatives) is the most celebrated sashimi tuna—deep red lean meat and richly marbled belly (otoro/chutoro) with melting fat. Flavour is meaty, clean, and profound when properly aged and cut. Overfishing made bluefin a conservation concern; legal, traced fish command premium prices. Serve raw as nigiri and sashimi, or briefly sear. Cooking through wastes the luxury texture. Buy only from transparent sources. Distinct from cheaper canned “tuna” species.

Global demand for sushi elevated bluefin prices and international fisheries pressure.
Quotas and conservation measures responded to declining bluefin stocks.
Traceability and aquaculture trials sought to stabilise premium bluefin supply.
