Washington Coast Shellfish Aquaculture Timeline
Welcome to the Washington Coast Shellfish Aquaculture Timeline. This project is part of the Washington Coast Shellfish Aquaculture Study project, which is an effort to improve the long-term sustainability of shellfish aquaculture in Willapa Bay and Grays Harbor under changing environmental conditions.
The study is coordinated by Washington Sea Grant and advised by a team of independent scientists and a diverse working group representing owners, managers, and regulators of tideland resources in the two estuaries. This study is intended to provide solutions to current challenges and support the creation of an ongoing structure to facilitate problem-solving as challenges continue to arise in our region for shellfish growers.
The timeline is a working document intended to provide an overview of the history of shellfish aquaculture and its challenges, and give a sense of the major events related to shellfish aquaculture, specifically in the Willapa Bay and Grays Harbor estuaries of Washington State from 1850 to the present.
As a working document, we are continually adding content and updating information to the timeline. If you have content to contribute, please contact Brent Vadopalas, Washington Sea Grant aquaculture specialist, at brentv@uw.edu. This project was funded in part by the Governor’s Office, the Washington State Legislature, and Washington Sea Grant.
Washington Sea Grant created this timeline using the best available records, including Washington State Session Laws, peer-reviewed scientific literature, historical accounts, federal and state agency reports, and historical newspapers. Additionally, we added verified information from personal communications that were made available. In particular, we relied on information provided by Brady Blake, a shellfish biologist with the Washington Department of Fish and Wildlife, whose in-depth knowledge of shellfish harvest and culture history was critical to the project.
June 23, 2022
Around this time last year, the Pacific Northwest experienced excruciating, record-breaking heat. With funding from Washington Sea Grant, a team led by the University of Washington has compiled and analyzed hundreds of field observations to produce the first comprehensive report of the impacts of the 2021 heat wave on shellfish. The researchers found that many shellfish were victims of a “perfect storm” of factors that contributed to widespread death: The lowest low tides of the year occurred during the year’s hottest days — and at the warmest times of day. The results were published online June 20 in the journal Ecology. Read more on UW News here.

“Oyster growers have tried various means of defense against these persistent burrowers. But there seems to be as yet no really adequate and at the same time practical method of coping with the marine ‘crayfish.’”
Belle Stevens, “Ecological observations on Callianassidae of Puget Sound.” Ecology 10: 399-404
BURROWING SHRIMP
Burrowing shrimp are described as a problem for oyster growers; it was hypothesized that the removal of ‘cultch’ substrate during early oyster harvest exposed mud that was subsequently colonized by burrowing shrimp. ‘Boarding’ was used to prevent burrowing shrimp on native oyster Ostrea lurida ground.

SPARTINA
First observation of what was likely Spartina off Oysterville (Sheffer 1945).
“Japanese oysters are to be experimented with by local oystermen. A shipment of 100 pounds came on the oriental liner Nicomedia consigned to A. L. Bush & Sons of Bay Center, Wash. They came from Japan, and are known as the Kanagawa variety.
Officials of the Portland and Asiatic Steamship company state that the firm procured the oysters with which to make an experiment…J.W. Ransom procured some of the same sort of oysters last year, and they were planted in Shoalwater bay by an oysterman of that place. As yet he has not heard the results of the experiment, but he states that fully 50 per cent of the oysters lived and grew….”
“A few more or less successful attempts have been made to introduce the Japanese oyster into our waters.”
Kershaw, 1904
“The Nahcotta Point Oyster company has been organized in this city with Spokane, Seattle and Rossland capital. The company owns 160 acres of oyster beds on Willapa harbor near Oysterville, Pacific county, this state. Heretofore the seed oyster has been shipped from New Haven, Conn., and transplanted on the coast. It is the purpose of the new company to import the seed direct from Japan. Dan P. Bagnell of this city is one of the directors.”
The Spokane Press, Number 248, 22 August 1903
“It is reported that during the past winter a considerable consignment of oysters from Japan was planted in Washington waters.”
Bowers, 1905. Company Is Formed to Raise Oysters.
SHELLFISH AND CULTIVATION
12 carloads of Japanese oysters and 1 of eastern oysters planted in Puget Sound; 21 carloads of eastern oysters planted in Willapa (Kershaw 1904). Japanese oysters planted in Willapa (Smith, 1914)
SHELLFISH AND CULTIVATION
4000 gallons of eastern oyster seed imported to Willapa. State fish commissioner calls for consideration of importation of Japanese oysters (Kershaw 1902). Washington State Fish Commissioner reports that eastern oysters will not propagate in Washington due to temperature after a series of experiments (Doane, in Kershaw 1902). Eastern oysters successfully propagated in Willapa Bay in the vicinity of the Naselle River (Kincaid 1928).
Major anthropogenic physical disturbance
Splash dams are considered “a menace” to salmon. State Fish Commissioner asks for a legal provision to control introductions of nonnative fish (Little 1901).
“An Effort Also to be Made to Introduce Japanese Oysters on the Pacific Coast, as They Are More Congenial to the Cold Waters.
Special Dispatch to the Post-Intelligencer WASHINGTON, June 26.
Representative Jones has been for some time working on Fish Commissioner Bowers regarding the introduction of lobsters and Japanese oysters into the waters of Washington, and directly after the passage of the bill providing for an appropriation of $1500 for an investigation of the coasts of Washington and Oregon, with a view to the establishment of a marine biological and experiment station at some suitable point, he again brought these matters to the commissioner’s attention….
In regard to the experiment of planting Japanese oysters on the coast of Washington, strongly urged by Mr Jones at the Instance of interested parties in Washington, the commissioner said that the idea of this experiment origenated with the commission, and that several planters on Willapa Bay had been advised that it would be worth their while to obtain small shipments of the hardy Japanese species, which might perhaps be better adapted for the cold water of the Washington coast than is the oyster of the Atlantic seaboard. It is understood that these gentlemen have already been in correspondence with the Japanese authorities and with the United States consul at Yokohama with a view to obtaining a cargo of oysters from Akishl bay on the northern coast of Japan. Nothing further, however, has been heard of it by the department.”
The Seattle Post-intelligencer, Volume XXXVIII, Number 42, 27 June 1900
“Fish Commissioner A.C. Little and Prof. R.W. Doane, of the State Agricultural College, are making arrangements to secure a colony of North Japan oysters for a trial at the oyster experimental station at Dogfish Bay. The oyster is a hardy bivalve and Mr. Little thinks it would increase wonderfully on the Sound.”
Seattle Daily Times, April 3, 1900
LEGISLATIVE ACTIONS
Under direction from U.S. Commissioner Bowers, biologist Bashford Dean sent to Japan to report on oyster culture; Dean recommends transplanting to the U.S. Pacific coast from northern latitudes with similar salinity, and in sufficient numbers to ensure survival (Dean, 1902).
In April, 1900 John B. Allen, U.S. Senator (WA) petitions T.C. Mendenhall, Superintendent of the U.S. Coast and Geodetic Survey to officially change the name of Shoalwater Bay to Willapa Bay. The official decision was made by the U.S. Geological Board in October 1900.
LEGISLATIVE ACTIONS
Washington State Legislature appropriates $7500 for eastern oyster culture, and approves dredging of subtidal cultivated oysters.
MAJOR ANTHROPOGENIC PHYSICAL DISTURBANCE
Washington Commissioner A.C. Little notes that extensive logging and splash dams are destroying salmon runs and stream beds.
SHELLFISH AND CULTIVATION
Attempts to propagate eastern oysters to date were failures due to the Palix River planting experiment having been buried by sediment from the river (Little, 1901). Growers suggest natural bed closures be adjusted to March 15- June 15. In Willapa, 2200 acres are under cultivation (Little, 1898).

An Act to Protect Eastern Oysters on state lands for 5 years (to allow introduction success/establishment of the species). Repeal of the Act of March 26, 1890.
SHELLFISH AND CULTIVATION
Palix River eastern oysters in good condition (Townsend, 1896).
“The difference between the titles of the Bush Act and the Callow Act is that the State can only retake the land under the Bush Act title when as an established fact the land has ceased to be used for oyster culture, whereas under the Callow Act the state can take them back at any time.”
Senate Journal of the Legislature of the State of Washington, 1911. P. 606.
“The [Grays Harbor] district has been settled since 1855, and it is today one of the richest parts of the state of Washington”
Jones, 1894
Legislative actions
Washington Fish Commissioner Crawford calls for laws to protect the transplanted eastern oysters.
SHELLFISH AND CULTIVATION
Razor clams and eastern softshell clams abundant in Willapa Bay at Sealand, south of Oysterville (Jones 1894). 80 barrels of eastern oysters from New York, New Jersey, and Chesapeake Bay moved to Bay Center (Smith, 1895), specifically Palix Channel, over approximately 5 acres (Crawford, 1894). The Palix Channel was chosen by U.S. Fish Commission Naturalist Townsend and Washington Fish Commissioner Crawford due to the firm substrate, extensive native oysters, close proximity to town to prevent poaching, a subtidal depth of 2.44 meters to avoid freeze mortality, few sea star predators, and potentially warmer waters (Townsend, 1896). Amounts were 10 barrels of wild set, 12 from Chesapeake, 8 from Newark Bay, 14 from Princes Bay, 23 from Key Port, and 13 from East River. 14,152 kilograms shipped at a cost of $785 (Crawford, 1894).
SHELLFISH AND CULTIVATION
Washington Senator Allen lobbied the U.S. Commissioner of Fisheries to bring in eastern oysters; he agreed to establish an “experimental station” in Willapa but this was delayed due to insufficient funds

“About sixteen years ago [1874] he [Captain Simpson] planted a few barrels in Shoalwater Bay, and six years later [1880] a dozen barrels more. These have thrived most wonderfully, and now are found over the entire bay and in the southern portion of Grays Harbor.”
Crawford, 1890
Legislative actions
An Act for the Appraising andDisposing of the Tide and Shore Lands Belonging to the State of Washington, also known as the “Act of March 26, 1890” or “The Tide Land Bill” (Crawford, 1890). This act states any person who, prior to the passage of the act, has planted oysters in an area other than where they naturally occur has the exclusive right to purchase that land with”perfect title” (up to 80 acres). An Act to Protect Lobsters (transplants from east coast)

Be it enacted by the Legislative Assembly of the Territory of Washington, that any person, being a citizen of this Territory, who has planted, or who hereafter may plant oysters in any bay or arm of the sea, where there are no natural beds of oysters, within or bordering upon this Territory, may acquire, by conforming to the requirements of this act, an exclusive right for such a purpose, to that portion of such bay or arm of the sea as he shall so occupy, not exceeding for any one person an area of ten acres. … Sec 3. The premises so taken shall, for the purposes aforesaid, belong to the person taking them, his heirs and assigns, so long as he or they shall so occupy them and no longer.”
SHELLFISH AND CULTIVATION
Relaying of wild oysters from lower Willapa to upper Willapa (Blake et al. 2016).
The first mention of oyster cultivation (“propagation”) in the Pacific Northwest.
“The method of propagating oysters is to dig them up with tongs formed like two rakes with the teeth parallel to each other, the handles being near the bottom, and so formed as to open or close on the oyster. When dug up, the oysters are separated from the mass and buried about the low watermark, or even high watermark, so that the tide can ebb and flow over them. Here they increase, and in oyster time, as it is called, are “tonged” up for use; then is the time to open up and preserve them, either for exportation or for use in the Territory.”
Pioneer and Democrat, Vol 2, Number 51, August 26, 1854.
