註釋"In June 20, 2016 the National Marine Fisheries Service (NMFS) received a petition from the Center for Biological Diversity (CBD) and 13 co-petitioners requesting that Pacific Bluefin tuna, Thunnus orientalis (PBF), be listed as endangered or threatened under the Endangered Species Act (ESA) throughout all or a significant portion of its range. After review of the petition, NMFS published a positive 90-day finding in the Federal Register (81 FR 70074) on October 11, 2016, concluding that the petitioned actions may be warranted and announcing that a formal status review would be conducted as required by the ESA. A Status Review Team (SRT) was tasked to conduct this review. Pacific bluefin tuna are a migratory pelagic species of fish primarily inhabiting the North Pacific Ocean and, to a lesser extent, in the Tasman Sea and around New Zealand. They are a top predator and have extraordinary swimming capabilities. Pacific bluefin are highly sought after for their flesh and both commercial and recreational fishing have contributed to a decline the population. To conduct this Status Review, the SRT considered a variety of scientific information from the literature, unpublished documents, and direct communications with researchers working on PBF, as well as technical information submitted with the petition and by the petitioners and others in response to the 90-day finding. The SRT evaluated the risks presented by several threats to the degradation/decline of the PBF population. After considering the severity of these risks as ranked by the SRT, the SRT performed an overall extinction analysis. All risk/extinction analyses were performed considering two time frames: 25 years and 100 years into the future"--Executive Summary.
