Stock SMART - Status, Management, Assessments & Resource Trends

Browse by Stock

Welcome to Stock SMART

Marine Fisheries in the United States are among the world’s largest and most sustainable. Fisheries support over a million jobs and contribute billions of dollars to the U.S. economy each year. NOAA Fisheries is responsible for managing U.S. marine fishery resources and uses sound science to balance productive and sustainable fisheries with healthy ecosystems. Stock assessments are an important tool NOAA Fisheries uses to monitor the condition of fish stocks and provide the science information that resource managers need to sustainably manage them.

Stock SMART is NOAA Fisheries' Stock Status, Management, Assessment, and Resource Trends web tool. Here, you can find applications to search, view, compare, and download the results of assessments for stocks managed by NOAA Fisheries. Keep reading to learn more about each of Stock SMART’s applications or click on a menu item to get started.

View summaries of individual stock assessment results for stocks managed by NOAA Fisheries. Historical assessments are available going back to 2005.

Chart Time Series

Explore time series results from stock assessments for common stock indicators including catch, abundance, fishing mortality, and recruitment (number of young fish). You can study estimates from one or more stock assessments for the same stock, or compare between stocks.

Plot Stock Condition

Visualize stock condition by plotting stock abundance (B) and fishing mortality (F) against their targets (B_MSY and F_MSY, respectively) estimated from the stock assessments. These charts are sometimes called 'Kobe plots' and can be used to quickly gauge stock health, as well as see how stock condition has changed over time.

Count Assessments

See how many assessments NOAA Fisheries completes each year, as well as the types of assessments that get done and the kinds of data that are used to support assessments.
