Scientists from the NOAA Alaska Fisheries Science Center have been working with fishermen in Sitka to understand the changes that they are witnessing in their marine ecosystems. These changes include shifts in target and non-target species, predator-prey dynamics, oceanographic and environmental factors, hatchery production, and ultimately fisheries earnings and participation. This graphic represents a summary of those changes and the latest scientific information that is available for them.

Indicator Status and Trends

We evaluate the status of the California Current Ecosystem by interpreting a variety of environmental, biological, economic, and social indicators. Current and historical indicator data are organized categorically, below, with a graphic showing the most recent 5-year trend and status relative to the long-term mean; the graphical interface allows for dynamic plotting and data download options.
