Marine Mammal Stock Assessment Program

Overview
In general, the Marine Mammal Protection Act (MMPA) prohibits the "taking" of marine mammals on lands or waters under U.S. jurisdiction. The MMPA also contains exceptions to this general prohibition on take, most of which require certain findings or determinations related to the effect of taking on marine mammal stocks. In addition, the MMPA directs NMFS and U.S. Fish and Wildlife Service (FWS) to evaluate the status of marine mammal populations and to prepare conservation plans to promote the recovery of depleted stocks of marine mammals.
The marine mammal stock assessment program supplies the information needed to
- Identify and assess the status of marine mammal stocks
- Make findings and determinations required to authorize take of marine mammals
- Evaluate the effects of human activities or natural environmental variability on marine mammals
- Provide a scientific basis to design conservation measures to minimize the impacts of human activities
- Promote recovery of depleted stocks of marine mammals

Data collection, analysis, and interpretation are conducted through marine mammal research programs at each NMFS Fisheries Science Center. Draft reports of research and assessment programs are subjected to quality assurance (peer review) within the Science Centers, by the three independent Scientific Review Groups, and/or by other qualified experts, such as editorial boards for scientific journals or the Center for Independent Experts.
Stock Assessment Reports
The products of NMFS' marine mammal research and monitoring program are used in a variety of ways, including the Marine Mammal Stock Assessment Reports. Draft stock assessment reports are peer reviewed by the independent regional Scientific Review Groups. Following peer review, the draft reports are made available for public review for 90 days. Once final, information summarized in these reports, or explained in detail in the references cited in the reports, contribute to:
- Permitting/authorization process
- Status reviews for listing as threatened or endangered under the ESA or depleted under the MMPA
- Conservation plans and recovery plans to promote recovery of depleted, threatened, or endangered species
- Reducing mortality and serious injury of marine mammals incidental to commercial fishing operations
