Pacific bluefin tuna joins list of threatened species

Sydney

THE Pacific bluefin tuna, a fish used in sushi and sashimi dishes, is at risk of extinction as the global food market places "unsustainable pressure" on the species and others, a conservation body warned on Monday.

The bluefin tuna joined the Chinese pufferfish, American eel, Chinese cobra and Australian black grass-dart butterfly on the International Union for Conservation of Nature's (IUCN) "red list" of threatened species.
