NOAA Fisheries prepares marine mammal stock assessment reports (SARs) annually, as directed by the Marine Mammal Protection Act. The reports are prepared in consultation with one or more of three regional Scientific Review Groups (SRGs) and are released as Draft SARs for public review and comment before being finalized.
NOAA Fisheries currently tracks 246 stocks of marine mammals with Stock Assessment Reports; 47 revised reports representing 76 stocks were updated for 2018.
In these 2018 draft reports, three stocks changed in status from “strategic” to “non-strategic” (Gulf of Maine humpback whale, Western North Atlantic long-finned pilot whales, and Western North Atlantic short-finned pilot whales), and one changed in status from “non-strategic” to “strategic” (Alaska bearded seal). Strategic Stock is defined by the MMPA as a marine mammal stock—
- for which the level of direct human-caused mortality exceeds the potential biological removal level;
- which, based on the best available scientific information, is declining and is likely to be listed as a threatened species under the ESA within the foreseeable future; or
- which is listed as a threatened or endangered species under the ESA, or is designated as depleted under the MMPA.
