Columbia River sea otters after 100y?

Interesting that the WA sea otters (a transient orca food source?) may be expanding their range from the NW coast of the Olympic Peninsula. Though the Salish Sea habitat is certainly appropriate for them, they apparently are rarely seen east of a line between Port Angeles and Race Rocks.

The reappearance of sea otters this month at the mouth of the Columbia River after an absence of perhaps as much as a century is heart-warming news in its own regard and also powerfully symbolic.
Russian hunters, eventually joined by Britons, Canadians and Americans, decimated a West Coast sea otter population once estimated at up to 300,000. Native people were drafted into the international trade, trading pelts for western goods, until only 1,000 to 2,000 otters remained when the slaughter finally was banned in 1911.
Even in the remote Aleutian Islands, sea otters have taken four steps forward and three steps back, with the population plunging from as many as 100,000 in the 1980s to around 6,000 by the year 2000. This may be because orcas shifted to preying on otters after environmental-related declines in their preferred menu items – seals and sea lions.
A self-sustaining population of otters has been reestablished along the northern Olympic Peninsula and the Strait of Juan de Fuca.

Who gets what % of the salmon?

This article is the first I’ve seen that juxtaposes salmon consumption rates of recreational fishers with a non-human predator, in this case, the CA sea lions. It will be an interesting exercise to see what factors reduce the runs on the various rivers of the West Coast where SRKWs forage annually. At 100kg of salmon per day per orca, is it possible SRKWs as an endangered species should have a more prominent seat in the annual development of salmon fisheries management policy?

No more free lunch on the Columbia

The leading argument against the killing of California sea lions that feast on endangered fish at Bonneville Dam is that the lions eat a “mere 4 percent” of the salmon and steelhead swimming upstream to spawn.
That figure is based on the share of all the salmon passing through Bonneville over an entire year. In fact, the sea lions are at Bonneville only a few months, and their impact is much greater on those stocks migrating in spring. NOAA Fisheries has estimated that removing 85 sea lions a year for two years could increase the returns of listed spring chinook and steelhead by up to 12.5 percent, a much higher return than the region would get from expensive improvements at dams.
Sport fishermen targeting hatchery fish, not endangered wild species, are allowed about 13 percent of the salmon run. Sport fishing, meanwhile, provides hundreds of millions of dollars in annual economic benefit

Snake River Salmon on KUOW

The most prominent appeal in this discussion was whether we can move away from litigation and towards more collaborative processes to restore the wild populations of Columbia salmon and steelhead. The agreement between 3 tribes and federal agencies (the “Columbia Basin Accords”) may be a step in the right direction. However, many feel the 2008 biological opinion (“BiOp”) is not acceptable and that the Federal agencies need to have their feet held to the fire (by Judge Redden, potentially .

The speakers made a strong suggestion that salmon fisheries will be closed again this year south of Cape Falcon. This is due to the poor condition of the Sacramento River runs, but will also presumably help protect runs from the Kalamath, Rogue, and OR coastal rivers. Ocean conditions north of Cape Falcon are looking about the same as last year (moderate) and we may have a stronger Columbia Coho year. The Pacific Fisheries Management Commission will meet next week; folks will probably start fishing around May 1.

Rob of Trout Unlimited was clearest: There are 1000s of miles of good habitat in the Snake River Basin (NE Oregon and Idaho). If you took down the 4 lower Snake River dams, you would enable wild runs to access that potential salmon refuge. We haven’t had a regional dialogue about realistic solutions to the goal of salmon recovery (to which most parties agree)! The courtroom encourages battle lines, not a serious, creative problem-solving approach. At the end of the day, the only way to have sustainable runs is to have access to habitat in healthy river systems. We’ve spent about $8B on salmonid recovery since initial listing in 1991 and the long-term trends are generally pointing towards extinction of wild runs.

Jerry (42′ salmon trolling fisherman) was also well-spoken: Rail is a good competitor for transport which is the main service provided by the lower Snake River. A problem with 400ton barges is that smaller wheat farmers must aggregate their product and can only get commodity prices. Rail cars could allow an organic wheat farmer to differentiate their product. This year we’re still looking at survival. Eight years from now I hope we’ll have honest commitments from the hydrosystem (the BPA and Army Corp have been too insulated by past administrations). Recent biological opinions have downplayed the impacts of the hydrosystem and have especially avoided the elephant in the room: the lower Snake dams.

NW salmon forecasts and fisheries dates

Here is an excerpt from yesterday’s WDFW announcement that describes the forecasts for many Columbia and Salish Sea salmon runs.  To Pat’s credit, there was a quick correction to a painful error (suggesting that adipose-clipped fish weren’t hatchery fish).  In conjunction with the process-map in the previous post, these dates should help us orca-advocates be in the right place at the right time to “speak for the whale’s” share of NW salmon…  Better speak now before they start shooting orcas like the CA sea lions lounging at the Bonneville debacle…

Preseason salmon forecasts developed by the Washington Department of Fish and Wildlife (WDFW) and treaty Indian tribes, were released today at a public meeting in Olympia.

Forecasts for chinook, coho, sockeye, pink and chum salmon mark the starting point for developing 2009 salmon-fishing seasons in Puget Sound, the Columbia River and Washington coastal areas. Fishery managers have scheduled a series of public meetings through March before finalizing fishing seasons in early April.

While several salmon runs are up this year, fishery managers still face a number of challenges in crafting fisheries that meet conservation goals for weak salmon stocks, said Phil Anderson, WDFW’s interim director.

“Conservation of wild fish will continue to be our top priority,” Anderson said. “We will work hard with tribal co-managers and our constituents to create fishing opportunities for hatchery fish while ensuring that we are successful in meeting conservation objectives for wild fish populations.”

One constraining stock this year is the Bonneville Pool hatchery fall chinook run, a major contributor to Washington’s coastal fisheries. Although the overall return of Columbia River fall chinook is forecasted to be higher than last year, catch quotas for chinook in the river and the ocean will likely be low because of the poor Bonneville Pool return and restrictions needed to protect wild salmon listed under the federal Endangered Species Act (ESA).

While salmon forecasts are up overall in the Columbia River, coho and chinook returns to Puget Sound are expected to be slightly down this year.

A few individual Puget Sound coho stocks, including the Skagit and Stillaguamish, are expected to return at low levels and will require additional protective measures this summer, said Pat Pattillo, salmon policy coordinator for WDFW. The overall summer/fall chinook forecast for Puget Sound, where wild chinook salmon are listed for protection under the federal ESA, is 222,000 fish, a slight decrease from last year’s forecast.

“It’s important that we continue working to recover and protect wild salmon populations in Puget Sound,” Pattillo said. “One management tool we can use that helps with those recovery efforts and allows us to provide meaningful recreational fishing opportunities is mark-selective fisheries.”

In the last two years, WDFW has added several recreational mark-selective fisheries for hatchery chinook in Puget Sound. These fisheries allow anglers to catch and keep abundant hatchery salmon – marked with a missing adipose fin – but require that they release wild salmon.

Pattillo said consideration of additional mark-selective fisheries for hatchery chinook in Puget Sound, as well as in the ocean, will be on the agenda during this year’s North of Falcon meetings.

A bright spot for Puget Sound this year is the pink salmon run. More than 5.1 million pink salmon are expected back to Puget Sound streams this summer, nearly 2 million more fish than forecasted in 2007. The smallest of the Pacific salmon species, the majority of pink salmon return to Washington’s waters only in odd-numbered years.

Another strong fall chum salmon return also is forecasted for Hood Canal and other areas of Puget Sound, where the run is expected to total nearly 915,000 fish. But a Lake Washington sockeye fishery is unlikely this year. The sockeye forecast is about 20,000, well below the minimum return of 350,000 sockeye needed to consider opening a recreational fishery in the lake.

Meanwhile, coho returns to several coastal rivers, including the Hoh and Quillayute, are expected to be up this year, Pattillo said.

State, tribal and federal fishery managers will meet March 8-13 in SeaTac with the Pacific Fishery Management Council (PFMC) to develop options for this year’s commercial and recreational ocean chinook and coho salmon fisheries. The PFMC establishes fishing seasons in ocean waters off the Pacific Coast.

Seven additional public meetings have been scheduled in March to discuss regional fisheries issues. Input from these regional discussions will be considered as the season-setting process moves into the “North of Falcon” and PFMC meetings, which will determine the final 2009 salmon seasons. The meetings are set for:

* March 4 – Grays Harbor fisheries discussion, 6 p.m.-8 p.m., Montesano City Hall, 112 N. Main St., Montesano.
* March 5 – Willapa Bay fisheries discussion, 6 p.m.-8 p.m., Raymond Elks Lodge, 326 Third St., Raymond.
* March 11 – Puget Sound commercial fisheries discussion, 10 a.m.-noon, WDFW Mill Creek Office, 16018 Mill Creek Blvd., Mill Creek.
* March 11 – Puget Sound recreational fisheries discussion, 6 p.m.-8 p.m., WDFW Mill Creek Office, 16018 Mill Creek Blvd., Mill Creek.
* March 16 – Columbia River fisheries discussion, 9 a.m.-3 p.m., Vancouver Water Resources Education Center, 4600 S.E. Columbia Way, Vancouver, Wash.
* March 19 – Final Grays Harbor and Willapa Bay fisheries meeting, 9 a.m.-5 p.m., Room 172 of the Natural Resources Building, 1111 Washington St. S.E., Olympia.
* March 19 – North of Falcon salmon fisheries discussion, 6 p.m.-9 p.m. Benton PUD, 2721 W. 10th Ave., Kennewick.

Two public North of Falcon meetings, which involve planning fishing seasons for Washington’s waters, including Puget Sound, also will take place in March. The first meeting is scheduled March 17 at the Lacey Community Center, and the second meeting is scheduled March 31 at the Lynwood Embassy Suites. Both meetings will begin at 9 a.m.

The PFMC is expected to adopt the final ocean fishing seasons and harvest levels at its April 4-9 meeting in Millbrae, Calif. The 2009 salmon fisheries package for Washington’s inside waters will be completed by the state and tribal co-managers during the PFMC’s April meeting.

Preseason salmon forecasts, proposed fishing options and details on upcoming meetings will be posted as they become available on WDFW’s North of Falcon website at http://wdfw.wa.gov/fish/northfalcon/ .

A map for including killer whales in NW fisheries managment

Just happened upon this nice synopsis of how WDFW views the various processes by which fishing harvests are governed in the Pacific Northwest. For me, this helps clarify which processes we killer whale advocates could influence to bolster the number of salmon and other fish that are available to feed the southern residents. As usual, the words “orca” or “whale” isn’t present in this document, though the may soon be included next to the reference to the ESA…

How salmon fishing seasons are set
Harvest rules built on foundation of
scientific surveys, computer models, joint deliberations
Managing Washington’s fisheries – in particular salmon – is acknowledged as one of the most complex natural resource challenges in the country, due to the interplay of biological and geographical factors.
The annual process of setting scientifically sound fishing seasons begins each year with a pre-season forecast of the abundance of various individual fish stocks.
After the biological information and data gleaned from coded wire tags is agreed to by the co-managers, they are assembled into a computer model that offers a snapshot of an upcoming season’s fishery under various regulation options. The results from these computer simulations are then compared to conservation goals, obligations under U.S.- Canada treaties, allocations for tribes and protection requirements for some wild fish population under the Endangered Species Act.

Loss of salmon smolts in BC and CA

An awareness seems to be dawning that salmon smolt mortality is increased by human activities — both in the nearshore environment and in river systems. A recent biological opinion regarding Sacramento salmon suggested that about 8% of the smolts entering the San Juaquin / Sacramento delta make it through to the ocean. This article mentions an early warning that the Chinook smolts that do make it to the ocean have been doing less and less well in Georgia Basin over the last 12 years. That doesn’t bode well for our southern residents who appear focus on returning Fraser Chinook for 80-90% of their summer diet…

Coho, chinook in ‘dramatic’ decline

But pink salmon survival rising in B.C.

By ROBERT McCLURE
P-I REPORTER

Coho and chinook are in decline — but curiously, pink salmon survival appears to be increasing, Richard Beamish of the Canadian Department of Fisheries and Oceans told participants in the biennial Puget Sound/Georgia Basin Ecosystem Conference.

Scientists have long known that only a small percentage of the juvenile salmon that leave freshwater rivers to live in the sea return to spawn at the end of their lives. But the new research shows that percentage has drastically decreased since 1980. In coho, it dropped from 10 percent to 0.5 percent, Beamish said. In chinook, it decreased from 1 percent to 0.1 percent.

Beamish’s research shows that over the past 12 years, the survival of coho in Georgia Strait in their first four months dropped dramatically. About 15 percent of the fish disappear in those first four months, Beamish said.

Oil Spill Risk Management: Strategies for the future

Intro by Miles (Chip) Boothe

Over 600 vessels have been escorted by the Neah Bay tug since it first started operating in 1999; 6 involved throwing lines to a vessel in distress.  This afternoon the legislature is looking at a new measure to fund the tug permanently (beyond the 1 year that Governor Gregoire recently promised) and transfer the burden of cost to the maritime shipping industry.

See Fred Felleman’s guest column in the Seattle Pi (Feb 4, 2009) [~40% of tankers calling on WA are single-hulled; WA has 5 refiners that process 9 billion gallons crude/yr;

Dan Doty: Slick Fixes for the Salish Sea – Restoring Natural Resources after Oil Spills

Prevention is important, but what happens if a spill occurs?  Three types of responses:

  • Restoration is handled by Natural Resouce Damage Assessment (NRDA; guided by State and Federal law).
  • Oil spill response (incident command system)
  • investigations

Most spills are small.  NRDA is WA compensation schedule ($1-100/Gal damages go into a fund that is used for restoration)

Bigger spills involve planning and preparation:

  • NRDA guidance and team organization, early assessment plans (EDCPs), training, science, monitoring
  • Initial chaos, logistical issues, though there is a pre-organized oil spill response system
  • Recommendations for conducting cooperative natural resource damage assessment (April 07 West Coast Joint Assessment Team)
  • Collection of data through ephemeral data collection plans and sampling “go kits” and caches (e.g. with Makah Tribe, Navy)
  • Key issue is staffing, training, drilling: field crews need Hazwoper Training, scientifically and legally defensible (chain of custody) data must be collected through specialized resource teams.  We’re incorporating a worst case drill into training of NRDA team.
  • One of the first tasks is to identify key resources at risk, focus injury assessments on highest priorities, look for baseline data to assess impacts.  So, baseline data is being collected and maintained (e.g. at Padilla Bay GIS).
  • Oil spills have sub-lethal and long-term effects on aquatic ecosystems (e.g. PAHs affect herring eggs)

Restoration is the goal of this whole process.  We need to invest in preparation to do a good job when a spill happens.

Evaluating Capacity to Respond to Large-scale Oil Spills in Puget Sound and the Georgia Basin, Jacqui Brown-Miller

Later this week the Washington Oil Spill Advisory Council will publish “Assessment of capacity in WA State to respond to large-scale marine oil spills.”  This is a synopsis of the assessment of what to do in the first 48 hours after a ~50k barrel spill.  The results of the study will likely guide upcoming policy revisions.

Response modes:

  1. recover oil with skimmers
  2. sensitive shoreline protection with booms
  3. in-situ burning and chemical dispersent
  4. shoreline clean-up in urgent phase (to keep that oil from moving further)
  5. wildlife response (usually doesn’t start until after 48 hours)

Results:

  • WA state has existing resources to recover only 9500-19500 barrels of a 50k barrel instantaneous release.
  • Numeric estimations accounted for senarios with various spill behavior, response tactics, swath width, recovery system efficiency and storage capacity.
  • Response capacity is highest near equipment caches; Port Angeles is highest; lowest are on outer coast.
  • It looks like ~32k feet of boom is stored in Mackaye Bay (or somewhere near Lopez Island)
  • 1400-1800 barrels may be dispersed; ~4k could be burned; we have optimistically 684 response personel; manual removal off beach would require 100s to 1000s of workers; mechanical removal should have an advance policy about when/where such “scraping off” could occur
  • Working on a hazing plan to keep marine mammals away.
  • Wave and wind limitations mean that mechanical recovery would be unimpaired 94% of the time in inland waters, but only ~25% of the time on outer coast.
  • Main uncertainties: availabililty of people and equipment (day of week, can multiple gear be deployed simultaneously?)
  • We need more on-water storage devices and earth-moving equipment and cleanup equipment (e.g. super-sacks).

Looking to the Future – Training, Drills, and Exercises, David Sawicki

Dept of Ecology has a  Spill Drill checklist that is aligned with the Northwest Area Contingency Plan and designed to test the functionality of the Incident Command System.  Federally, there is National Preparedness for Response Plan document.

The present state: Incident Command System is probably best in the world

Future state: Increased focus on field activities (not incident command post where we are excellent)

  • shoreline cleanup
  • wildlife rescue/rehabilitation
  • dispersant approval / application process
  • volunteer management
  • staging area management
  • decontamination

We need to do this through workshops and coordinated training (leveraging proximal refineries and response organizations).  We need to move past repetitive checklist 3-year cycle approach.   “Many of us are ready for graduate school.”  We also need to develop more realistic goals (only a mag 9 earthquake would cause some of the scenarios we train for…)

Panel discussion

Kathy Fletcher: Prevention is the most important thing we can do.  Right now we have a 5cent/barrel tax that funds our prevention and response activities, but the revenue is unpredictable because if oil is shipped out of WA the tax is refunded.  The Oil Spill Advisory Council needs to advise the legislature on ways to stabilize the revenue (though the Governor has suggested abolishing the Council itself).   This March 24th will mark the 20th anniversary of the Exxon spill where lack of vigilance was the main reason the damage was so grave.

Richard Wright: Runs largest private, non-profit Marine Spill Response Company (4M barrel clean-up capacity, nationally??).  WA State is very well prepared and we have an MOA with Burrard, a Canadian counterpart.  A single phone call will access their full resources.

Linda Pilkey-Jarvis: possible big spills are from 10k barrels to ~3M barrels.  We have gained rules in latest regulatory framework that make review of plans optimal, e.g. standards for skimmer efficiency equipment.  We’ve pushed equipment caches to outer coast areas and San Juan Islands.  Some companies are close to compliance, but many have a ways to go as we begin this 3 year process.  Before plans are approved, we go into field to verify procedures and resources.

Long-term PCB fate and bioaccumulation

N
long-term fate and bioaccumulation of PCBs in Puget Sound,

Models of contaminant kinetics:

  • Davis 2004 includes an active 10cm layer in Puget Sound
  • Field data: In Puget Sound 1400kg PCBs (estimates range from 600-3500) are in active layer compared with ~7kg in water and ~40kg in biota (estimated from Sandy’s measurments)
  • [PCB] in water: measured mean ~60-100 ng/gD.
  • Model says PCB mass in sediment will plateau in ~50yrs at 1000-8000kg and depend mostly on on-going external loading ( from 25 to 500 kg/yr) not historical because it is getting buried by new sedimentation)
  • Atmospheric deposition is l~50kg/yr and ocean exchange may be 100s kg/yr… these numbers are uncertain but may mean PCB mass is actually increasing in Puget Sound now.
  • Long-term means of 20-200kg/year is about what must have been loaded to get to current measured masses.

Since 1990s, English sole PCBs have been increasing (but not in other species).  This may be caused by on-going external loading.  Our model predictions match measured biota within a factor of 2.

External loading in Puget Sound is probably non-point source from watersheds.  Policies that control general toxics loading and runoff should help reduce PCB loading.

Scott: External loading is still a problem?!  The orca community should be lobbying HARD for global PCB bans!

Toxics assessment process in Puget Sound

James Maroncelli

Phase 1 of toxic loadings to PS initiated in 2006 by a coalition (PSAT+WA Ecology+…): realized that air deposition was an important pathway

Phase 2: spring 07 $300k from EPA, $300 from Ecology TPA, $55k NOAA funded all programs (because we established a framework for project prioritzation)

  1. Surface runoff
  2. Atmospheric depositino
  3. Permitted wastewater
  4. CSO discharges
  5. exchange with ocean
  6. exchange with contaminated sediments
  7. flux to/from biota

Sources

  1. residential areas contributed ~3/4 of loading
  2. permitted contributed <1%

Phase 3: hope to attain funding from national estuary, trying to align with action agenda, but didn’t want to wait in part because Norm Dix wanted to start fixing problems asap.  Year 1 projects focused on analyzing surface runoff, sediments, biota, including $310k from WA legislature on atmospheric deposition (via PSP).  First of these projects will report in June, 2009.

Phase 3, year 2: starting to use action agenda for guidance, PSP wanted an inventory of toxic chemicals by spring 2010 to inform second version of Action Agenda which is due in Sept 2010.  Projects: 3-6 may be funded, proposals due to EPA March 1; Transferring responsibility for toxic loading to PSP science panel.  Joel Baker says funding will be “pragmatic.”  Decision process for potential Oct 2009 funding is to be more formal and rely on recommendations of PSP Science Panel.

A toxics-based biological observing system (tBiOS) for PS

Lyndal Johnson, NWFSC

Pre-spawn mortality of salmon is occurring in restored urban streams.  It is associated with urban development, road traffic, and storm water runoff, but concentrations of toxics aren’t high enough to account for the convulsions and lethargy.  We suspect a synergistic effect of multiple pollutants.

PAHs affect embryo development in spawned herring eggs (e.g. heart defects).

These problems would not have been identified without monitoring for contaminants as well as biological effects.  Sometimes the source is the food web, not water or sediments.  Contaminants may be having damaging effects at sub-lethal concentrations (e.g. copper at 5-20 ng/l decreasing predator evasion and other behaviors that depend on olfaction).

What monitoring is currently being done in PS as part of PSAMP?

  • contaminants are measured in a few species
  • liver disease is monitored in English sole
  • bethic community structure and sediment toxicity to invertebrates in bioassays

What is a biologically-integrated Observing System for Toxics (tBIOS):

  • assess exposure and effects in biota across ecologically relevant habitats and food webs
  • focus research projects (30% of monitoring budget) which piggyback on monitoring framework
  • link design of monitoring program to conceptual models (e.g. food webs, toxic loading and transport)
