Is Disaster Imminent for Tunas?
Tunas occasionally make it into mainstream news, and when they do, the circumstances (for continued survival of the species) usually sound pretty dire. However, a scientist at the University of Washington, on cfooduw.org, found that, at least through 2014 (per available data), only eight of 22 commercial tuna stocks had an abundance below that which would produce maximum sustainable yield. Two stocks, says Ph.D. candidate Maite Pons — Pacific bluefin and bigeye in the western central Pacific — are fished hard enough to threaten their collapse. But that’s two of 22. She concludes by saying, “The abundance of tunas and their relatives has declined from preindustrial levels, but in general, they are at sustainable levels,” with a few noted exceptions (and some showing signs of rebuilding at this time).
