Stock Assessment Reports

Section 117 of the Marine Mammal Protection Act, as amended in 1994, requires the U.S. Fish and Wildlife Service to report periodically on the status of marine mammal stocks within Alaskan waters. Each stock assessment includes a description of the stock's geographic range, a minimum population estimate, current population trends, current and maximum net productivity rates, optimum sustainable population levels and allowable removal levels, and estimates of annual human-caused mortality and serious injury through interactions with commercial fisheries and subsistence hunters. Stock assessment reports are used to evaluate the progress of fisheries towards achieving the goal of zero mortality and serious injury to marine mammals.
