Tuna

Large, fast-swimming pelagic fish (*Thunnus spp.*) with dense, meaty red flesh, frequently compared to beef. Yellowfin (ahi) and bigeye are prized raw for sushi and sashimi; bluefin (the most prized and most endangered) delivers the fattest toro belly cuts; skipjack dominates canning. Sears beautifully with a rare center; overcooks quickly to chalky dryness. Buy only from sources rated Best Choice or Good Alternative by Seafood Watch — some populations are severely overfished.
