Guidelines for Assessing Marine Mammal Stocks

The Marine Mammal Protection Act provides some general guidance for developing marine mammal stock assessment reports. More detailed guidelines have been developed by NOAA Fisheries and U.S. Fish and Wildlife to provide a uniform framework for the consistent development and approach to preparing the reports.

The Marine Mammal Protection Act provides only general guidance on assessment methods and on the content of marine mammal stock assessment reports. As a result, NOAA Fisheries and the U.S. Fish and Wildlife Service have held a series of workshops since 1994 to develop guidelines that may be consistently applied nationally to marine mammal stock assessments.
