  Walleye pollock eastern Bering Sea food web.

The Resource Ecology and Ecosystem Modeling Program (REEM) 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 NMFS assessment surveys and include diet dat by predator species, year, and region. Once a species is selected a list of available diet data by region is available, with a list of years included for that species and region combination. For consistency, prey items were grouped into 92 common categories (shown here). REEM maintains a customized prey dictionary (pdf), (csv) based on former NODC codes. Data Description (pdf, html).
