The most basic goal of the Marine Mammal Protection Act (MMPA) (16 U.S.C. 1361) is to maintain marine mammals as a “significant functioning element in the ecosystem of which they are a part.” The MMPA translates that ecosystem goal to the population level by aiming to ensurethat marine mammal stocks do not fall below or are restored to their optimal sustainable population sizes. Although the main goals of the MMPA are
defined at the ecosystem and population levels, its primary focus of regulation is at the level of the individual. When the MMPA was enacted, marine mammal populations were threatened by hunting and by deaths resulting from becoming entangled in nets or otherwise killed in fisheries.
