2017 Status of Alaska Marine Ecosystems Considerations - Eastern Bering Sea

The goals of the Ecosystem Considerations report are to (1) provide stronger links between ecosystem research and fishery management and to (2) spur new understanding of the connections between ecosystem components by bringing together the results of diverse research efforts into one document. Beginning in 2016, we split the report into four separate documents, one for the Gulf of Alaska, Aleutian Islands, eastern Bering Sea, and the Arctic.

Alaska Ecosystem Models

Scientists at the Alaska Fisheries Science Center work on several different types of models single-species, multispecies and ecosystem models that incorporate predation and bioenergetics (transfer of energy among trophic levels). Below are some of the…

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.

Alaska Food Web Research

A key area of fisheries and ecosystem research is collecting and analyzing data about food chains in the North Pacific. Data are put into environmental assessments, and single-species and multispecies models so we can better understand the relationships between organisms, and to their physical surroundings.

Alaska Fish Stomach Database

The Alaska Fisheries Science Center's Resource Ecology and Ecosystem Modeling Program maintains a database of the food habits of North Pacific groundfish. As of March 2016, the Fish Food Habits Database contains diet information from 410,283 stomachs.

Alaska Groundfish Diet Data

The Resource Ecology and Ecosystem Modeling Program at the Alaska Fisheries Science Center maintains a North Pacific groundfish diet data time series that dates back to the early 1980s for many species. Diet data are from samples collected during NOAA Fisheries assessment surveys and include diet composition by predator species, year, and region.
