While it doesn’t have to count license plates or tolerate bony elbows, the silvery Pacific herring does have a special spot in the middle of Puget Sound’s food web.
Growing on a diet of the many tiny planktonic crustaceans that float through Washington’s marine waters, as much as 70 percent of Puget Sound herring are, in turn, feed for numerous marine animals, such as seabirds, marine mammals, and other fishes.
Pacific herring live in 18 distinct zones in Puget Sound. One of those critical spots is Quartermaster Harbor between Vashon and Maury islands.
As part of an ongoing commitment to ensure the state’s busiest waterway remains suitable habitat for the many species that rely on it, the Washington State Department of Natural Resources (DNR) plans to remove old 170 creosote-saturated pilings and debris from seven sites around Vashon and Maury islands.
Nestled on eelgrass and marine algae on the sea floor, Pacific herring eggs are delicate. They have an especially high mortality rate when exposed to creosote, a mix of some 300 chemicals that leach into marine waters as pilings age and break up.
Less eggs means less herring, which means less food for the salmon and shorebirds that find them so delicious.
