Porbeagle Shark


What's New

In response to two petitions to list porbeagle shark (Lamna nasus) under the Endangered Species Act (ESA), and in light of new information that we have about porbeagle sharks, we have prepared a new 90-day finding.


These petitions were originally received in January, 2010. In response, we published a “negative” 90-finding in July, 2010, in which we concluded that, due to increasing numbers and stability in some stocks, coupled with new and continuing national and international management efforts, the petitions to list this species under the ESA were not warranted. 

The 2010 finding was challenged by the Petitioners, and on December 12, 2014, the Court ordered us to prepare a new 90-day finding. Our new 90-day finding is based primarily on new information that has become available since 2010, including a new Canadian assessment of the Northwest Atlantic stock and new information in recent proceedings from the International Convention for the Conservation of Atlantic Tunas (ICCAT), regulatory documents, published literature, and Federal Register notices as well as the information contained in the original petitions.
