This indicator evaluates the abundance values and their trends of the two Hood Canal summer-run chum salmon populations as measured by the number of natural-origin adult fish on the spawning grounds. Abundance estimates here do not include hatchery-origin fish or fish taken in harvest or by predators like orcas. The indicator is intended to reflect the goal of achieving wild population recovery of Hood Canal summer chum, which are federally listed as threatened.
Annual percent change in spawner abundance from 1999 to 2021 for two Hood Canal summer chum salmon populations (Hood Canal and Strait of Juan de Fuca). The lines show the 25th to 75th credibility intervals (CIs). CIs represent a range of values the true annual percent change likely falls within.
No targets are currently set for this indicator.
