Alaska Physical And Oceanographic Research

Physical and oceanographic conditions affect where fish and crab species spawn, feed and develop. This information has important implications for future fish and crab population size.

Alaska Research On Salmon Ecology And Bycatch

Scientists at our Auke Bay Laboratories conduct research to understand ecological processes that drive salmon populations in the Gulf of Alaska and the Bering Sea. They also monitor and analyze bycatch of salmon in other commercial fisheries for groundfish.

Recruitment Energetics and Coastal Assessment Fish Processing and Food Habits Research

Recruitment Energetics and Coastal Assessment scientists provide fish processing services to several Auke Bay Laboratories. The goal is to better understand recruitment mechanisms and processes that describe the growth and survival of these populations relative to their prey, predators, and potential competitors. Sample processing in our labs focuses on measurements of fish size, energy density, and diet and feeding success of juvenile salmon and associated fish, as well as the abundance and composition of their zooplankton prey fields.

Alaska Ecosystem Monitoring and Assessment

By understanding the relationship between fish species and their marine environment, we are able to enhance the accuracy of our fish stock estimates.

Northeastern Bering Sea Ecosystem Assessment

The fishery and oceanographic survey in the Northeastern Bering Sea combines surface trawl and midwater acoustics to collect indices on fish size, relative abundance, energetic status, distribution, and diet.

Southeastern Bering Sea Ecosystem Assessment

The fishery and oceanographic survey in the southeastern Bering Sea combines surface trawl and midwater acoustics to collect indices on fish size, relative abundance, energetic status, distribution, and diet.

Bering Arctic and Subarctic Integrated Survey

In order to improve monitoring and enforcement efforts, the North Pacific Anadromous Fish Commission (NPAFC) scientists developed BASIS (Bering-Aleutian Salmon International Survey) during 2002, a comprehensive survey of the Bering Sea epipelagic ecosystem.

Arctic Ecosystem Research in Alaska

We investigate how changing Arctic conditions affect Arctic fish feeding, growth, and survival.

Salmon Research In Alaska

Pacific salmon play an important role in Alaska’s marine ecosystems and are a valuable commercial, recreational, and subsistence resource. NOAA Fisheries scientists forecast salmon harvests, assess the impact of commercial fisheries on salmon, and evaluate how salmon populations respond to environmental changes. The information we provide helps managers make science-based decisions to ensure sustainable fish populations, fisheries, and fishing communities.

Southeast Alaska Coastal Monitoring

NOAA Fisheries supports the Southeast Alaska Coastal Monitoring program, which studies juvenile salmon in the coastal waters of the Gulf of Alaska ecosystem.
