A new proposal by the National Oceanic and Atmospheric Administration (NOAA) could bring about protection for oceanic whitetips in US waters under the Endangered Species Act (ESA). However, discussions currently under way in Congress are making the future of the ESA, and all listed species, uncertain.
In September 2015, wildlife advocates Defenders of Wildlife issued a petition for the protection of the oceanic whitetip. After almost a year of gathering information about the status of the species, NOAA concluded that it is likely to become endangered throughout all, or a significant portion, of its range within the foreseeable future due to its vulnerability to being taken as by-catch in pelagic fisheries. The high value of the oceanic whitetip’s large fins in the international fin trade, despite its protected status under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) was also a consideration. Accordingly, in late December 2016 NOAA released a proposal to add the oceanic whitetip to the ESA as a threatened species.
To assess the whitetip’s status, NOAA consulted with numerous experts, including geneticist Cassandra Ruck of the Save Our Seas Foundation’s Shark Research Center. Ruck used genetics to investigate the species’ global population structure and global trends in its genetic diversity. ‘Understanding population structure is critical for defining management units for scientifically based management strategies,’ she explained. ‘Genetic diversity assessments also enable managers to make priority decisions, as they can reveal particularly vulnerable populations with lower genetic diversity, as well as opportunities to maintain populations with higher genetic diversity.’
The 90-day public comment period on the listing ended on 29 March 2017 and a final decision is expected by 29 December 2017. However, the efforts of Defenders of Wildlife and NOAA may bear little or no fruit for conservation, following a recent Senate hearing to ‘modernise’ the ESA. Some officials argue that the Act’s legislation impacts on their ability to create jobs, particularly in the energy sector.
