Current Management Issues

On August 8, 2017, NOAA Fisheries announced a not warranted 12-month finding on a petition to list the Pacific bluefin tuna (Thunnus orientalis) under the Endangered Species Act (ESA). We completed a comprehensive status review of the species and concluded that the species is not currently in danger of extinction throughout all or a significant portion of its range nor likely to become so within the foreseeable future. Therefore, we have determined that the species does not warrant listing as threatened or endangered under the ESA at this time.


On June 20, 2016, we received a petition from Center for Biological Diversity et al. to list the Pacific bluefin tuna as threatened or endangered under the ESA. The petitioners also requested that critical habitat be designated concurrent with a final listing.

On October 11, 2016, we published a positive 90-day finding determining that the petitioned action may be warranted for the Pacific bluefin tuna. We conducted a comprehensive status review of this species to determine if the petitioned action was warranted. Scientific and commercial information pertaining to this species was accepted until December 10, 2016.
