The U.S. National Marine Fisheries Service has proposed to designate the Sakhalin Bay-Nikolaya Bay-Amur River Stock of beluga whales (Delphinapterus leucas) as a depleted stock of marine mammals pursuant to the Marine Mammal Protection Act.
This action is being taken as a result of a status review conducted by NMFS in response to a petition to designate a group of beluga whales in the western Sea of Okhotsk as depleted.
NMFS believes that the biological evidence indicates that the group is a population stock as defined by the MMPA, and that the stock is depleted as defined by the MMPA.
