What we know about fish populations in Puget Sound

Puget Sound is home to 59 listed populations of Chinook salmon, steelhead, and bull trout, most of which continue to decline. Puget Sound Chinook salmon show very few signs of recovery. During the past 10 years, the majority of populations show that adult Chinook abundance has remained static. None of the populations of Puget Sound Chinook salmon meet recovery goals for abundance of natural-origin (wild) spawners. Furthermore, productivity remains low for most populations.

Indicator data

Adult Abundance Summary Table

The majority of populations of Chinook salmon in Puget Sound are far from reaching their abundance recovery goals. In some years, a few populations have reached goals but not consistently during the past 10 years. These populations are in the Skagit River system and are considered some of the healthiest in the region. Because they occasionally have met their high productivity goals, but never their low productivity goals, none of the Puget Sound populations of Chinook salmon could be considered exceeding their abundance recovery goals.
Recovery goals for Puget Sound steelhead are under development and available for public review at the National Oceanic and Atmospheric’s Administration’s Web site.

Data needed for population trend analysis

We are improving how we track the abundance of young salmon, but more data and analysis are needed to determine any population trends. Of the listed fish stocks measured, only 6 of 18 showed an increase. How are juvenile fish measured?
