US Federal Georegulations - Marine Mammal Protection Act

US National Oceanic and Atmospheric Administration (NOAA)
  • Added 10 Sep 2016
  • Updated 30 Aug 2018

The Marine Mammal Protection Act (MMPA or Act) prohibits, with certain exceptions, the "take" of marine mammals in U.S. waters and by U.S. citizens on the high seas, and the importation of marine mammals and marine mammal products into the U.S. The MMPA gives the Secretary of Commerce, working through the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service, authority and duties under the Act for all Cetaceans (whales, dolphins, and porpoises) and Pinnipeds (seals and sea lions, except walruses), and gives authority for other species of marine mammals to the Secretary of the Interior, working through the U.S. Fish & Wildlife Service. The Secretaries are also required to prepare and periodically revise stock assessments of marine mammal stocks (section 117). In addition, the Secretary of Commerce must publish in the Federal Register and revise at least annually a list of commercial fisheries that categorizes the fisheries based on the incidence of serious injury and mortality of marine mammals (section 118(c)).

These data represent the unofficial boundaries of the respective federal georegulations found herein, as of 2016. Learn how these specific boundaries were created and find source material used, by referencing the metadata of each federal georegulation found here: When investigating geo-regulatory boundaries near the boundary edges, users should consult the most up to date applicable jurisdictional boundaries from all respective authoritative sources. To determine other federal georegulations that apply to an area, please reference the Federal Georegulations Identification service found here: These data are intended for coastal and ocean use planning and do not serve as a legal delineation of any law.
