Listing Endangered and Threatened Wildlife and Plants; Notice of 12-Month Finding on a Petition To List the Pacific Bluefin Tuna as Threatened or Endangered Under the Endangered Species Act

We, NMFS, announce a 12-month finding on a petition to list the Pacific bluefin tuna (Thunnus orientalis) as a threatened or endangered species under the Endangered Species Act (ESA) and to designate critical habitat concurrently with the listing. We have completed a comprehensive status review of the species in response to the petition. Based on the best scientific and commercial data available, including the status review report, and after taking into account efforts being made to protect the species, we have determined that listing of the Pacific bluefin tuna is not warranted. We conclude that the Pacific bluefin tuna is not an endangered species throughout all or a significant portion of its range, nor likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. We also announce the availability of a status review report, prepared pursuant to the ESA, for Pacific bluefin tuna.
