Native Olympia oysters expected to gain a new foothold in Sinclair Inlet

A massive amount of oyster shell — some 1,500 cubic yards — will be dumped into Sinclair Inlet near Gorst next week to lay the groundwork for a healthy population of native Olympia oysters.

Limited numbers of Olympia oysters have been growing in Sinclair Inlet, hanging on since long ago, said Betsy Peabody, executive director of Puget Sound Restoration Fund, which is managing the operation. Existing oysters probably just need the right substrate for their larvae to attach, grow and ultimately expand the native oyster population.

The $300,000 project — which will deposit the equivalent of 150 dump-truck loads of Pacific oyster shells — will be the largest one-time application of shells anywhere in Puget Sound, Betsy told me. Her organization has undertaken similar projects in other areas, including Liberty Bay near Poulsbo, Dogfish Bay near Keyport, Dyes Inlet near Bremerton and Port Gamble Bay on Hood Canal.

The shells, which came from commercial oyster farms, will be washed off a 200-foot barge using a jet of water beginning Tuesday and taking up to four days, according to the current schedule. The shell will cover some 15 acres of tidelands toward the middle of the inlet where Highway 166 branches off Highway 16.

This washing process typically creates a patchwork of shell covering about 80 percent of the bottom while 20 percent remains bare, according to plans for the project. The thickness of shell on the bottom will vary, reaching up to 3 inches in some places. No eelgrass or other sensitive vegetation was found during surveys of the tidelands to be covered. The property is owned by Kitsap County.

In the early 1900s, Sinclair Inlet was used as an 122-acre oyster reserve for protecting seed stock, which could be purchased by commercial oyster growers. Oyster reserves throughout Puget Sound were largely forgotten after Pacific oysters — a different species imported from Japan — began to dominate the oyster market.

Olympias went extinct in some areas, killed by pollution, shoreline development or other factors. In a few areas, habitat was largely undisturbed and the original oyster species persevered. But many embayments, including Sinclair Inlet, were able to support only a fraction of their historic populations.

“Olys evolved in this area and managed to maintain a foothold in the most surprising areas, despite what we’ve thrown at them over time,” Betsy said. “They are tough little critters. You can even find them in places where everything else is plastic. Building back their densities seems like a good thing to do.”

Oysters have a number of good qualities besides being a favorite food of many people. They can filter out plankton that can trigger low-oxygen conditions. Plankton also reduce sunlight needed for critical vegetation, such as eelgrass.

The 19 areas in Puget Sound declared a high priority for Olympia oyster restoration.

Washington Department of Fish and Wildlife has designated Sinclair Inlet as one of 19 priority restoration sites for Olympia oysters in the Puget Sound region. See “Plan for Rebuilding Olympia Oyster (Ostrea lurida) Populations in Puget Sound…”(PDF 559 kb)

In natural oyster beds, young oysters are able to set and grow on the shells of their ancestors, often forming oyster beds or reefs that help perpetuate the substrate for future generations. Sedimentation and damage to the shoreline can interrupt the process and eliminate the substrate needed for the oyster to survive. Putting down a lot of shell to create new substrate has proven to be the best way to boost the population in most areas of Puget Sound.

If the Olympia oysters do well in Sinclair Inlet, eventually more shell could be brought in to expand the growing area, Betsy said. If, however, natural production of oyster larvae is not enough, PSRF could develop a broodstock program by utilizing its shellfish hatchery near Manchester, as has been done for other areas. If that were to happen, adequate numbers of Olympia oysters from Sinclair Inlet would be used to produce the oyster seed, thus maintaining the genetic diversity of the inlet.

In 2010, Puget Sound Restoration Fund established a goal of restoring 100 acres of Olympia oyster habitat with shell placed in bays where the native oysters are expected to do well. The Sinclair Inlet project will bring the total to 85 acres, with other areas in the planning stage to help the group meet its goal by the end of next year.

About half of the $300,000 being used for the Sinclair Inlet project came from the federal Natural Resources Conservation Service, with other funding from the Washington Department of Ecology, Kitsap County and PSRF. The Suquamish Tribe also participated in the project.

Old bulkhead to be removed on Ross Point, a major surf smelt beach

Ross Point, the most popular fishing spot for surf smelt in Kitsap County, will become a little more friendly to the little fish following the removal of a concrete bulkhead along the shore of Sinclair Inlet.

The bulkhead removal, scheduled to begin Aug. 12, will create more spawning area for surf smelt, an important food source for salmon and other fish. Smelt also are favored eating by some people, who typically catch them with dip nets.

In addition to increasing smelt habitat, the project will enhance the migration of young salmon along the southern shore of Sinclair Inlet. Like most bulkheads built in the tidal zone, this 84-foot-long structure forces juvenile salmon to swim into deeper water out from shore, making them more vulnerable to predators.

Leaders from ‘national estuaries’ seek increased funding from Congress

Laura Blackmore, executive director of the Puget Sound Partnership, was among six leaders from so-called “national estuaries” who spoke to Congress last week about the need for increased funding.

Laura Blackmore, Puget Sound Partnership

The natural beauty of Puget Sound and its recreational opportunities have attracted people and businesses, including 11 of the nation’s Fortune 500 companies, Laura told the House Transportation and Infrastructure Committee.

“Unfortunately,” she added, “Puget Sound is also slowly dying. Southern Resident orcas, chinook salmon and steelhead are all listed under the Endangered Species Act. We continue to pollute our waterways and our shellfish beds, and habitat degradation outpaces restoration.”

New facts and findings about the European green crab invasion

The ongoing story of the European green crab invasion offers us scientific, social and even psychological drama, which I would like to update by mentioning four new developments:

  1. The somewhat mysterious finding of a partially eaten green crab on the Bellingham waterfront,
  2. A “story map” that spells out much of what we know about European green crabs in Puget Sound, including maps, photos and videos.
  3. Information about Harper Estuary in South Kitsap and other areas where groups of citizen scientists are on the lookout for green crabs, and
  4. Reports of a new breed of European green crab in Maine that attacks people and may prove to be more destructive than the green crabs that have lived in the area for a very long time.

Ghost-net busters are entering a new era of hunting and removal

My mind is unable to grasp, in any meaningful way, how much death and destruction was caused by fishing nets that were lost and abandoned through the years.

Filmed in 2007, this KCTS-9 video describes the problem of ghost nets and a project that would eventually remove nearly 6,000 nets.

Nearly 6,000 of these so-called “ghost nets” have been pulled from the waters of Puget Sound over the past 17 years. Until removed, they keep on catching fish, crabs and many more animals to one degree or another.

We can support responsible fishing, but those of us who care about Puget Sound must never again allow lost nets to be forgotten, as if “out of sight, out of mind” ever worked for anyone.

The latest concern, as I reported last month in the Encyclopedia of Puget Sound, is that 200 or more ghost nets are still lurking at depths below 100 feet, which is the level considered safe to operate by divers with normal scuba gear. Remotely operated vehicles (unmanned submarines) are being developed to go after nets remaining in deep water, where they are killing crabs and many other deep-water species — including rockfish, some of which are listed under the Endangered Species Act.

Laura Blackmore takes over as director of Puget Sound Partnership

Laura Blackmore, deputy director of Puget Sound Partnership, will slide into the agency’s executive director position when she comes into work next week.

Laura has built a reputation as a facilitator, helping to meld diverse ideas into cohesive policies. That experience should serve her well in the director’s post, where she will take on the primary role of shaping the direction of the Partnership for the coming years.

“Puget Sound is in trouble, and we know what we need to do to fix it,” Laura told me. “It took us 150 years to get into this mess, and it will take us awhile to get out. What we need is the political will to keep going.”

A new federal law recognizes Washington’s maritime heritage

The Maritime Washington National Heritage Area — which now encompasses about 3,000 miles of saltwater shoreline in Western Washington — was created yesterday within a wide-ranging lands bill signed into law by President Trump.

Created to celebrate the maritime history and culture of Puget Sound and Coastal Washington, the Maritime Washington NHA is the first designated area of its kind in the United States to focus entirely on maritime matters.

The designation is expected to provide funding to promote and coordinate maritime museums, historic ships, boatbuilding, and education, including discussions of early marine transportation and commerce in Washington state.

“We are thrilled about this,” said Chris Moore, executive director of the nonprofit Washington Trust for Historic Preservation. “The stories we want to convey are important to so many people.

Salmon report mixes good and bad news, with a touch of hope

The story of salmon recovery in Washington state is a mixture of good and bad news, according to the latest “State of the Salmon” report issued by the Governor’s Salmon Recovery Office.

It’s the usual story of congratulations for 20 years of salmon restoration and protection, along with a sobering reminder about how the growing human population in our region has systematically dismantled natural functions for nearly 150 years.

“We must all do our part to protect our state’s wild salmon,” Gov. Jay Inslee said in a news release. “As we face a changing climate, growing population and other challenges, now is the time to double down on our efforts to restore salmon to levels that sustain them, our fishing industry and the communities that rely on them. Salmon are crucial to our future and to the survival of beloved orca whales.”

The report reminds us that salmon are important to the culture of our region and to the ecosystem, which includes our cherished killer whales. It is, however, frustrating for everyone to see so little progress in the number of salmon returning to the streams, as reflected in this summary found in the report:

Salmon treaty designed to boost spawning count and feed the orcas

Allowable fishing for chinook salmon in the waters of Canada and Southeast Alaska will be cut back significantly this year as a result of a revised 10-year Pacific Salmon Treaty between the United States and Canada.

The goal of the updated treaty is to increase the number of adult chinook returning to Washington and Oregon waters, where they will be available to feed a declining population of endangered orcas while increasing the number of fish spawning in the streams, according to Phil Anderson, a U.S. negotiator on the Pacific Salmon Commission.

Most chinook hatched in Washington and Oregon travel north through Canada and into Alaska, making them vulnerable to fishing when they return. Changes to the treaty should reduce Canadian harvests on those stocks by about 12.5 percent and Alaskan harvests by about 7.5 percent, Phil told me. Those numbers are cutbacks from actual harvests in recent years, he said, so they don’t tell the complete story.

New online magazine describes life in and around Puget Sound

John F. Williams, a Suquamish resident who has been creating dramatic underwater videos for years, recently launched a new online publication called Salish Magazine. Its goal is to help people to better understand the ecosystem in the Puget Sound region.

For those of us who live in the region, John and his Still Hope Productions have helped us visualize and understand what lies beneath the waves and up the streams of Puget Sound. The video “Is this where Puget Sound starts?” (shown below) is a good example of the video production. Other videos can be found on Still Hope’s website.

The new online publication shifts to the use of more words, along with photos and videos, to explain the connections among living things. The first issue includes extensive articles on sea anemones, barnacles, sea stars, mussels and glaciation, spiced up with art, poetry and personal stories. Download the magazine as a huge PDF (56.6 mb) file or open it in iBooks.

The second issue of Salish Magazine is about the importance of forests, with articles on forest character, forest restoration, barred owls and more, as well as poetry, essays and lots of photos, all combined in a web design that combines variable scrolling with pull-down menus.

As John describes it, “A key focus of the magazine is to illustrate the interconnectedness woven through our ecosystems, using lenses of history, science, and culture.”

The first two issues are free, although a subscription is expected to be announced next year. Meanwhile, one can sign up for newsletters on the Subscribe webpage. Salish Magazine is published by the nonprofit firm SEA-Media.

Speaking of environment news, I hope everyone is familiar with Puget Sound Institute and its online newsletters. The December issue includes a quiz on Pacific herring and articles on rockfish, Puget Sound vital signs, the Clean Water Act and recent research papers.

Puget Sound Institute, an independent organization affiliated with the University of Washington, strives to advance an understanding of Puget Sound through scientific synthesis, original research and communication. PSI receives major funding from the Environmental Protection Agency.

One can subscribe to the PSI newsletter, blog and alerts to articles in the Encyclopedia of Puget Sound on the Subscribe webpage.

Full disclosure: I am employed half-time by Puget Sound Institute to write in-depth articles about scientific discoveries and ecological challenges in the Puget Sound region.

Further note: A previous version of this post stated incorrectly that Still Hope Productions is a nonprofit company.
