Shellfish harvesting closure in Port Madison and Miller bays

BREMERTON — Marine biotoxins that cause paralytic shellfish poisoning (PSP) have been detected at high levels in shellfish samples from the Miller Bay Marina located near Suquamish on Miller Bay in Kitsap County, the Kitsap Public Health District reports.

As a result, the state Department of Health and the Kitsap Public Health District have closed recreational shellfish harvesting for all species of clams, oysters, and mussels in Port Madison Bay and Miller Bay. The closure area includes all of Miller Bay, and Port Madison Bay from Point Jefferson south to Point Monroe on the north shore of Bainbridge Island to the Agate Pass Bridge, including all bays and inlets in this area.

Samples of mussels collected on Oct. 7 from the Miller Bay Marina contained PSP toxin concentrations of 275 micrograms per 100 grams of shellfish tissue.

Shorelines are closed to harvesting when toxin levels exceed 80 micrograms per 100 grams of tissue.
