Pacific Herring Sampling Locations

Baseline Stations
Distinct stocks of Pacific herring are monitored at 3 pre-spawning locations: Semiahmoo in the Strait of Georgia (northern Puget Sound), Port Orchard in central Puget Sound and Squaxin Pass in southern Puget Sound. The fish are sampled from pre-spawning aggregates near known spawning grounds, so the sampling locations vary somewhat from year to year.

Focus Stations
In 2000, concerns over major declines in the abundance of the Cherry Point herring stock prompted a focus study to examine the possibility that contaminants are affecting their survival. Adult males, egg skeins from mature females, and spawned eggs were collected in the Cherry Point area to compare against those collected at other Puget Sound stations.
