Lab In A Can To Help Identify Toxic Algae Off Washington Coast

After a massive toxic algae bloom closed lucrative shellfish fisheries off the West Coast last year, scientists are turning to a new tool that could provide an early warning of future problems.

Scientists at the National Oceanic and Atmospheric Administration and the University of Washington last week deployed the so-called ocean robot about 50 feet into waters off the coast of La Push, Washington, near a known hotspot for toxic algae blooms.

The tool, dubbed “a laboratory in a can,” will remain in the water until mid-July, providing real-time measurements about the concentrations of six species of microscopic algae and toxins they produce, including domoic acid.

The instrument is equipped with sensors and cellular modems that will allow it to take water samples and send that information to shore three times a week for the next several weeks. Scientists plan to deploy it again in the fall, another critical time for harmful algae blooms.

Last year, dangerous levels of domoic acid were found in shellfish and prompted California, Washington and Oregon to delay its coastal Dungeness crabbing season. Washington and Oregon also canceled razor clam digs for much of the year.

Ray Hilborn receives international fisheries science prize

May 26, 2016 — Ray Hilborn, a UW professor of aquatic and fishery sciences, this week will receive the 2016 International Fisheries Science Prize at the World Fisheries Congress in Busan, South Korea.

The award is given to Hilborn by the World Council of Fisheries Societies’ International Fisheries Science Prize Committee in recognition of his 40-year career of “highly diversified research and publication in support of global fisheries science and conservation,” according to a news release.

For Hilborn, who has received numerous awards for his research — including the Volvo Environment Prizeand the Ecological Society of America’s Sustainability Science Award — this recognition is particularly significant because it comes from other experts in fisheries science.

“It’s very gratifying in that it is experts in fisheries that are doing the evaluation and selection for this award,” Hilborn said.

JES HATHAWAY: Getting Past Greenpeace

May 17, 2016 — I will admit, I was relieved to see a piece from the broader scientific community (not just fisheries science) that defends Ray Hilborn against the attack Greenpeace launched against him last week.

Hilborn defended himself quite well almost immediately, which is no surprise, given his reputation for being even-keeled, plainspoken and precise.

But this bulleted defense from Southern Fried Science, “Six thoughts about Greenpeace’s attack on Ray Hilborn,”doesn’t just defend Hilborn, it’s a defense of the scientific community. As it should be, because the Greenpeace attack was in effect a declaration of war on all scientists who specialize in a field of study. If you get close enough to a subject, you’re bound to work with groups that have a vested interest in the same subject. That’s how research specialists do their work. What Greenpeace is claiming is that if a scientist does not list in full his or her entire CV of funding with every article, op-ed, interview, paper, panel discussion, etc., then they’re hiding something.

Hilborn: Greenpeace attacks funding issue because science is sound

May 13, 2016 — University of Washington fishery scientist Ray Hilborn has responded to Greenpeace’s accusation that he often fails to disclose industry funding when writing or speaking about the extent of overfishing.

In a letter sent Wednesday to university president Ana Mari Cauce, Greenpeace filed a complaint against Hilborn’s research practices, and asked for an investigation.

Hilborn, over the years, has been a critic of Greenpeace as well as other environmental groups and researchers he accuses of overstating the impacts of fishing on marine resources.

“Greenpeace is unable to attack the science I and my collaborators do; science that threatens their repeated assertions that overfishing is universal and that the oceans are being emptied,” he said in a response on his blog.

“On the contrary it is clear that where effective fisheries management is applied, stocks are increasing not declining, and this is true in North America and Europe as well as a number of other places. Overfishing certainly continues to be a problem in the Mediterranean, much of Asia and Africa.”

ANDREW THALER: Six thoughts about Greenpeace’s attack on Ray Hilborn.

May 13, 2016 — First, some background:

Or, just read Trevor Branch’s timeline.

1. The idea that scientists should declare every source of funding over the history of their career on every scientific paper is impractical and wholly unnecessary in a connected world where anyone can effortlessly access a researcher’s CV. Non-profit NGOs only need to file one financial disclosure statement every year, not attach it to every press release, and that is also perfectly adequate.

2. Transparency in funding is important. Claiming that a researcher is failing to disclose funding information when that information clearly is available and accessible erodes public trust in science and makes everyone’s job harder. Greenpeace didn’t send a team of stealth lawyers on an o’dark thirty raid of the UW mainframe, they asked for the information and were given it.

Fisheries scientists to address flaws in past forage fish research

WASHINGTON (Saving Seafood) – May 2, 2016 – Dr. Ray Hilborn, a marine biologist and fisheries scientist at the University of Washington, has launched a new initiative aimed at addressing key issues surrounding forage fish science and the impacts of forage fishing on predator species. Dr. Hilborn’s Forage Fish Project is one of several scientific efforts occurring in the next few months to expand the existing body of scientific research on forage fish.

Comprised of 14 renowned fisheries scientists from around the globe, the Forage Fish Project held its inaugural conference last month in Hobart, Australia, where it identified shortcomings in the existing forage fish research. Specifically, it found several issues with work produced by the Lenfest Forage Fish Task Force, whose April 2012 report, “Little Fish, Big Impact,” concluded forage fish are vulnerable to overfishing, among other findings.

The Forage Fish Project, which includes two members of the Lenfest Task Force, began work to address these flaws, with the goal of producing an accompanying study later this year.

In Hobart, Project members found that most of the models used in previous forage fish studies, like the Lenfest Task Force report, left out factors such as the natural variability of forage fish stocks, and the extent of size overlap between fisheries and predators. The group also found multiple indications that the Lenfest study greatly overstated the negative impact of forage fishing on predator species.

“Most [food web] models were not built with the explicit intention of evaluating forage fish fisheries, so unsurprisingly many models did not include features of forage fish population biology or food web structure that are relevant for evaluating all fishery impacts,” according to minutes from the Hobart meeting.

Two upcoming fishery management workshops will also evaluate forage species on the East and West Coasts of the U.S., the first organized by the Southwest Fisheries Science Center and the Pacific Fishery Management Council. The workshop, which will be held in La Jolla, Calif., from May 2-5, will focus on how to improve stock assessment methods for northern anchovy and other coastal pelagic species. Attendees will evaluate model-based assessment approaches based on routinely assessed pelagic species from around the world, consider non-assessment approaches to estimate fish stocks, and develop recommendations for how the SWFSC should evaluate coastal pelagic fish stocks in the future.

A similar forage fish workshop will be held May 16-17 in Portland, Maine. This workshop will focus on Atlantic herring, with the goal of establishing a rule to specify its acceptable biological catch (ABC), the recommended catch level for any given fish species. An effective ABC rule will consider the role of Atlantic herring in the ecosystem, stabilize the fishery at a level that will achieve optimum yield, and address localized depletion in inshore waters.

Ultimately, these various forage fish workshops and projects are striving to use the best available science to update previous research and determine sound management practices for forage species.

Professor Ray Hilborn wins 2016 International Fisheries Science Prize

April 11, 2016 — SAVING SEAFOOD — Professor Ray Hilborn, of the University of Washington’s School of Aquatic and Fishery Sciences, was recognized by the World Council of Fisheries Societies for his contributions to fishery management science.

“Professor Hilborn has had an extremely impressive career of highly diversified research and publication in support of global fisheries science and conservation. Throughout his 40-year career, Ray has been a model of dynamic and innovative science, and in the application of this work to the ever-changing problems of fisheries management and conservation in both marine and freshwater ecosystems. Professor Hilborn’s Prize will be awarded at the World Fisheries Congress in Busan, South Korea in late May.”

In recent years, Professor Hilborn has been one of the organizers of the Ram legacy Database at the University of Washington, which is the most complete global database on fish stocks, biomass surveys and catch history ever assembled.  The resulting analysis and modeling from this database have not only united many fisheries scientists around the world who had been portrayed by the media as opposing each other in terms of fisheries conservation issues, but the database has also served to highlight a road map for fisheries conservation efforts over the next twenty years.

As a result of these efforts, Hilborn has been instrumental in changing the perception that fish stocks were being fished to extinction and instead has shown that when fisheries management principles are properly applied, strong stock recoveries take place.

Frustrated by the public misperception about the actual state of major fisheries, Hilborn and other colleagues have created cfood a website scientists use to communicate with journalists and the general public about fisheries science issues.  The database, and website, have been particularly helpful in countering organizations who use distorted or outdated fisheries science to alarm regulators and the public.

Here’s How the Number of Fish in the Ocean Could More Than Double by 2050

March 31, 2016 — Fish populations around the world have been decimated by overfishing — but new research suggests that this could soon change if the world got its act together.

Fishermen around the world could haul around 16 million more metric tons of fish than they do today and generate $53 billion more in profits while more than doubling the amount of fish left in the oceans by 2050 if they adopted sustainable fishing practices, according to a report published in the Proceedings of the National Academy of Sciences.

Those practices would involve a so-called “catch share” model of fisheries management. In catch share systems, regulators figure out the maximum number of fish that can be hauled from the sea without hurting future fish populations. The regulators then divvy up that amount of fish into shares that are distributed to individual fishermen. Each fisherman has a set amount of fish they are can catch in the year.

“If you can reform fisheries and eliminate their competitive nature, there’s enormous room for profits, catch, and abundance,” said Ray Hilborn, a professor of marine biology and fisheries science at the University of Washington who co-authored the study with researchers at the University of California, Santa Barbara and the Environmental Defense Fund.

Good Management can Lead to a More Sustainable Future

March 30, 2016 — A new paper in the Proceedings of the National Academy of Science shows that there is a triple bottom line, that abundance, catch and profit can all be increased by reforming fisheries management in places where it has not been reformed. It provides the most comprehensive estimates of the status of global fisheries and shows that the large fish stocks of the world that provide 95% of global catch on average are at about the abundance that would produce long term maximum yield, and fishing pressure on average is below traditional targets. Less than 20% of fish stocks appear to be overfished by U.S. standards.

Comment by Ray Hilborn, University of Washington, @hilbornr:

The paper by Costello and others (including myself) Global fishery prospects under contrasting management regimes that appeared March 28 in PNAS, provides the most comprehensive assessment of the status and potential of global fisheries. Its key finding is that when stocks are overfished, most can recover within 10 years if the appropriate management measures are taken. This means that globally we could have more catch, more fish in the ocean and more profit. Most of the potential for this “triple bottom line” comes from Asia where fisheries are both large, and at present, mostly unmanaged. We must distinguish between fisheries that are reformed and those that are poorly regulated and remain in a race to fish.

Diving deeper into the estimated current status of fish stocks, we find it depends greatly on the size of the stock. Although the paper examined the status of 4,324 individual stocks, just 719 of them provide 96% of the catch. From the perspective of catch, profitability, and fish in the ocean, it is the 719 that are critical and feed us.

Research finds trawling not as devastating as often portrayed

November 23, 2015 — An ongoing two-year independent study on trawling and its effect on benthic sea life — species that live on sea floors where trawling occurs – has found that the practice may not be as devastating as it is portrayed by some NGOs.

The study called, ‘Trawling: Finding Common Ground on the Scientific Knowledge Regarding Best Practices’, is being funded by the Walton Foundation and the Packard Foundation in partnership with the National Fisheries Institute, and is being done by a group of international scientists who are collecting and assessing data of global sea floors where trawling occurs.

The major data collection and analysis for the project has been completed, including assessments of mobile bottom contact gear in Europe, Australia, New Zealand, Argentina, South Africa and most of the US, making it six times more extensive than and previous compilations.

According to Ricardo Amoroso of the University of Washington, who presented the data at this year’s Pacific Marine Expo in Seattle, public perception of trawling is often negative. Common public beliefs include the equivalent of 10 football fields are trawled every four seconds and that trawling is turning the seafloor into a desert.
