Marine Mammal Stock Assessment Reports by Species/Stock
NOAA Fisheries annually prepares marine mammal stock assessment reports for all marine mammals in U.S. waters.
This page provides all marine mammal stock assessment reports by species/stock. We also provide this information as regional stock assessment reports.
Note: Individual reports are only posted when they are revised from a previous year.
Posting of the 508 compliant versions of the older years is in process. If there is a year that you need now, please contact us at 301-427-8400 or email pr.webmaster@noaa.gov to request it. Provide the species name and year that you need.
