Results of the Steller sea lion (Eumetopias jubatus ) surveys in Alaska, June–July 2025

The Alaska Fisheries Science Center’s Marine Mammal Laboratory (MML) conducts annual crewed aircraft and vessel-based surveys of known terrestrial Steller sea lion (Eumetopias jubatus) rookery and haulout sites to collect visual counts and high-resolution imagery. In 2025, the crewed aircraft survey effort was cancelled because of budget limitations. The vessel-based team surveyed the endangered western distinct population segment (DPS) of Steller sea lions in the western and central Aleutian Islands regions.

Abstract

The Alaska Fisheries Science Center’s Marine Mammal Laboratory (MML) conducts annual crewed aircraft and vessel-based surveys of known terrestrial Steller sea lion (Eumetopias jubatus) rookery and haulout sites to collect visual counts and high-resolution imagery. In 2025, the crewed aircraft survey effort was cancelled because of budget limitations. The vessel-based team surveyed the endangered western distinct population segment (DPS) of Steller sea lions in the western and central Aleutian Islands regions.
