bluefin

For one thing, Americans hardly eat imperiled bluefin tuna at all.

Other environmental experts think the bluefin study might be more notable for its novelty, rather than its alarm.

Bluefin species have registered up to six times higher than federal standards.

(Earlier this year, an 800-pound bluefin fetched nearly $750,000).

Correction: An earlier version of this article stated that eating several pounds of Pacific bluefin could make someone feel sick.
