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.

Habitat And Ecological Processes Research In Alaska

The Habitat and Ecological Processes Research Program develops scientific research that supports implementation of an ecosystem approach to fishery management.

Habitat and Ecological Processes Research Regarding the Loss of Sea Ice

Climate change is causing loss of sea ice in the Bering, Chukchi and Beaufort Seas. Addressing ecosystem-related shifts is critical for fisheries management, because nationally important Bering Sea commercial fisheries are located primarily within the southeastern Bering Sea, and for successful co-management of marine mammals, which at least thirty Alaska Native communities depend on.

Ecology of Small Fish Living in Shallow Coastal Waters (Neritic Zone) in the Gulf of Alaska

A major reason we study larval fish in the Gulf of Alaska is to advance our understanding of the mechanisms that control fish population structure and production.

Ecosystem Research In Alaska

We study Alaska ecosystems through a combination of scientific observation and model development to examine how environmental change, including climate change, affects the long-term health of fish, crabs, and other marine life and the communities that rely on them. Our goal is to provide ecosystem information to fishermen, resource managers, and others so they can make informed decisions ensuring sustainable fisheries and maintaining ecosystem and community resiliency.
