New Confluence looks at Oregon Fisheries

Posted on by

Confluence: Science & Fishermen Working TogetherOregon’s Fisheries: Scientists and Fishermen Working Together is the theme of the summer edition of Confluence, Oregon Sea Grant’s new magazine, available now in print and online.

The cover story, “You Talk and You Change the World,” highlights Sea Grant’s fruitful efforts to connect  Oregon’s coastal fishing communities with ocean and coastal researchers. Written by Nathan Gilles (the program’s 2011 communications intern, now a working journalist), the story traces more than a decade of work by Sea Grant Extension agents such as Ginny Goblirsch to get fishermen and scientists talking – and listening – to each other in small, regular, informal meetings. The resulting Scientist and Fishermen Exchange (SAFE) program provides researchers with the experience-proven insights and knowledge of those who spend their lives working with marine resources – and occasionally with valuable opportunities to conduct research directly from fishing vessels. At the same time, fishermen gain early access to research results, and the opportunity to play a part in the science that helps shape marine resource policy.

Additional articles look at new seafood processing techniques that are generating products, markets and jobs on the south coast, recent discoveries about how hypoxic “dead zones” may be affecting the reproductive capacity of certain fish and other organisms, and a surprising discovery by Sea Grant researcher Guillermo Giannico about where some Willamette Valley salmon spend their winters.

Published three times a year, the new magazine is available – with added video and other content not included in the print edition – at http://seagrant.oregonstate.edu/confluence, where a downloadable .pdf version is also available. Print copies are also available, free, by emailing  sea.grant.communications@oregonstate.edu (please include a name and mailing address).

Fishermen invited to Webinar on groundfish research

Posted on by

West Coast fishermen are invited to take part in a June 5 Webinar ,”West Coast Groundfish Fishery – Reducing Weak Stock Risk While Improving Profit for Fishermen.”

In an attempt to protect the groundfish fishery from stock collapse, fisheries regulators are considering shifting to a type of catch share system called ITQ, or  “individual transferable quotas.” Such a system sets a species-specific total allowable catch, typically by weight and for a given period of time.

With funding from Sea Grant programs in Oregon, California and Washington, researchers from the University of California at Santa Barbara and the University of Washington are attempting to  identify emerging ecological, social and economic impacts of the transition to an ITQ system. Can strategies be implemented that help fishermen avoid risk from catching weak stocks, while enhancing profit?

The free webinar, from 10 am to 11 am PDT, will present an overview of the research project and its primary questions.

Space in the Webinar is limited; seats can be reserved at https://www4.gotomeeting.com/register/126483927. (System requirements: PC- Windows 7, Vista, XP or 2003 Server; Mac – OSX 10.5 or newer).

Astoria becomes world surimi capital

Posted on by

Jae ParkEver wondered about the crab-flavored fish protein in your seafood sandwich, “crab” salad or California sushi roll?

It’s surimi, a fish protein paste made into various shellfish-flavored products.

Earlier this month, Oregon State University’s Seafood Lab on Marine Drive hosted the 20th annual Surimi School, a gathering of global industry representatives and researchers that made Astoria for one week the epicenter of expertise on the globally popular, gelatinous fish protein you’ve likely had in one form or another.

About 40 students from surimi plants, surimi seafood (finished product) plants and others from accessory industries attended lectures and took part in surimi labs.

Jae Park, an OSU professor seen as the pre-eminent expert on surimi, founded the OSU Surimi Technology School in 1993 in Astoria. He started similar institutes in Bangkok in 1996 and in Paris in 1999.

For most of the school’s first decade, Oregon Sea Grant invested in the surimi program’s development and success with grants to support Park’s research into ways to improve the texture of surimi, and with direct contributions to the surimi school. A number of Park’s research publications were published by Sea Grant as well.

“The academic and industry languages are different,” said Park. “With that mentality, I found there was a great need to build industry-academia partnerships.”

His answer has been to bring in academic and industry experts from around the world to Astoria every May for the last 20 years, sharing knowledge between the two groups and enhancing everyone’s understanding of the ever-changing surimi industry.

Hatchery salmon threaten wild populations, scientists say

Posted on by

A newly published collection of more than 20 studies by leading university scientists and government fishery researchers in Alaska, British Columbia, Washington, Oregon, California, Russia and Japan provides mounting evidence that salmon raised in man-made hatcheries can harm wild salmon through competition for food and habitat.

“The genetic effects of mixing hatchery fish with wild populations have been well-documented,” says journal editor David Noakes* from Oregon State University. “But until now the ecological effects were largely hypothetical. Now we know the problems are real and warrant more attention from fisheries managers.”

The research volume, published in the May issue of Environmental Biology of Fishes, brings together 23 peer-reviewed, independent studies carried out across the entire range of Pacific salmon, including some of the first studies describing the impact of hatcheries on wild salmon populations in Japan and Russia.

The studies provide new evidence that fast-growing hatchery fish compete with wild fish for food and habitat in the ocean as well as in the rivers where they return to spawn. The research also raises questions about whether the ocean can supply enough food to support future increases in hatchery fish while still sustaining the productivity of wild salmon.

“This isn’t just an isolated issue,” says Pete Rand, a biologist at the Wild Salmon Center and a guest editor of the publication. “What we’re seeing here in example after example is growing scientific evidence that hatchery fish can actually edge out wild populations.”

Losing wild fish would mean losing the genetic diversity that has allowed salmon to survive for centuries. Unlike hatchery fish, wild salmon populations have a range of highly specialized adaptations to the natural environment. These adaptations not only help them return to their home streams to spawn, but also increase their ability to withstand environmental changes like increases in ocean temperature and extreme variations in stream flows. Hatchery fish, as the name implies, are hatched from eggs fertilized in a controlled environment and raised in captivity until they are big enough to release into the natural environment. They lack the genetic diversity of wild fish that provides insurance against fisheries collapses.

What’s fresh on the Oregon coast?

Posted on by

Dockside salesA highlight of visiting the Oregon coast is bringing home seafood that’s just about as fresh as it gets.

But how do you know what’s in season when you’re there? Regulatory fishing seasons change from year to year, and it can be hard for a lay person to keep track of them.

Sea Grant Extension agent Kaety Hildenbrand has compiled her annual guide to “What’s Fresh on the Oregon Coast”, detailing the seasons for the most popular seafood caught off our shores: Salmon, halibut, Dungeness crab, albacore tuna, pink shrimp, flounder, sole and lingcod.

You can check the list on our Website, and download a free, printable .pdf to tuck into your travel kit.

While you’re at it, check out Kaety’s video on the Oregon Sea Grant YouTube channel, explaining what consumers should look for when buying fish straight off the boat:

Task force calls for forage fish harvest cuts

Posted on by

Sardines at the Monterey Bay AquariumCORVALLIS, Ore. – A task force that conducted one of the most comprehensive analyses of global “forage fish” populations is strongly recommending that world governments tighten catch limits on sardines, anchovies and other crucial prey species.

The Lenfest Forage Fish Task Force calls for restricting harvest of such forage fish so that they can continue to serve as critical prey for larger species, including salmon, cod and tuna, as well as for dolphins, whales, penguins and seabirds.

The report concludes that the fish are “twice as valuable in the water as in a net.”

“Forage fish are essential components of marine ecosystems,” said Selina Heppell, an Oregon State University fisheries ecologist and one of the authors on the report.  “The status and importance of each species can be difficult to evaluate because many of them migrate long distances and they can fluctuate dramatically in abundance.

“There also are regional differences in how the fisheries are managed and the relative health of the population,” added Heppell, an associate professor in OSU’s Department of Fisheries and Wildlife and past recipient of Oregon Sea Grant research support. “The West Coast sardine fishery, for example, is carefully monitored. They have a ‘harvest control rule’ that sets the harvest at about 10 percent of the overall stock, and when the population gets below a certain level, they stop fishing.

New Oregon Sea Grant publication probes the mysteries of hypoxia

Posted on by

Hypoxia: How Is It Affecting Ocean Life and Why?The causes and effects of hypoxia have been confounding marine scientists since the 1970s, when so-called “dead zones” first started appearing in oceans and large lakes. Currently there are more than 400 dead zones worldwide.

How did this happen, and how can it be fixed?

As Nathan Gilles, Oregon Sea Grant’s 2011 Science Communication Fellow, spent time with Sea Grant-funded researchers Francis Chan, Lorenzo Ciannelli, and Stephen Brandt, he uncovered a rich and complex story. That story is revealed in Oregon Sea Grant’s new publication, Hypoxia:How Is It Affecting Ocean Life, and Why?

The publication is available for purchase, and as a free download.

OPB highlights Sea Grant researcher

Posted on by

Oregon Sea Grant’s Guillermo Giannico and his study of the role flooded farmlands can play in fish survival are the subject of a new episode of Oregon Field Guide, broadcast on on Oregon Public Television this week.

Giannico, a fisheries ecologist with OSU’s Department of Fisheries & Wildlife who also serves as Sea Grant Extension fisheries specialist, was part of a team that set out a few years ago to learn whether dry-all-summer ditches that criss-cross Willamette Valley agricultural lands might house fish during the wet winter months.

What they found surprised them – and some of the farmers, too: A thriving winter habitat for several species of native fish.

Port Orford launches national tour of Ocean Frontiers film

Posted on by

PORT ORFORD  – Ocean Frontiers, a new feature-length film about ocean management and conservation, will launch its national tour in Port Orford,  which stars in the film as an example of how science and fishing can work together to manage marine resources.

The debut screening starts at 5 pm Saturday, Feb. 11 at the Savoy Theatre in downtown Port Orford. followed by a reception in the nearby Community Building, with Oregon Governor John Kitzhaber,  First Lady Cylvia Hayes, representatives of state and local government and members of the Port Orford Ocean Resource Team (POORT) expected to attend. A second screening is scheduled for  4 p.m. Sunday.

Tickets are $10 and are available only online, at www.oceanfrontiersportorford.eventbrite.com

The film will also be shown at the Performing Arts Center in Newport at 7 pm Feb. 22.

Port Orford is one of several US coastal communities featured in the 80-minute film, which tracks the evolution of marine resource management from a “maximum allowable catch” approach to a growing recognition that resources are finite, and need to be managed for the future as well as the present. The film explores the shift toward  ecosystem-based management and marine spatial planning tools that rely on science, and an informed and engaged public. Communities from the Pacific Northwest to Boston Harbor, the Florida Keys, the Gulf of Mexico and even the cornfields of Iowa are featured.

POORT figures prominently in the film as an example of how resource users,  scientists, conservationists and others can work together to help understand, protect and manage ocean areas for the benefit of the resource – and the people who depend on it. Ongoing collaboration between fishermen and scientists in the south coast community was a strong factor in the state’s decision to establish one of Oregon’s first marine reserves at Redfish Rocks, just off  Port Orford.

Oregon Sea Grant has supported the community-based effort since its early days, helping bring fishermen and scientists together and providing information and assistance as the group grew and evolved. Sea Grant helped the community design and conduct surveys and interviews that let the town  build its first  long-form community profile to give resource managers greater insight into how fisheries reach deep into the community’s social and economic life. The format and interview has since been applied to other Oregon coastal towns, and is proving to be a model for communities  elsewhere in the US.

Documentary follows Sea Grant-supported research into salmon disease

Posted on by

Jerri Bartholomew with juvenile salmonKLAMATH FALLS – A new documentary, airing Feb. 7 on Southern Oregon Public Television, looks at the work of an Oregon Sea Grant-funded research effort to understand more about a lethal parasite that can infect wild salmon in the Klamath River and elsewhere in the Northwest.

Dr. Jerri Bartholomew, a microbiologist and director of Oregon State University’s salmon disease laboratory, has been studying Ceratomyxa shasta since she was an undergraduate. The parasite is a major cause of mortatlity in juvenile salmon, and may infect up to 80 percent of outmigrating juveniles in the Klamath River.  Bartholomew’s work – much of it funded by Sea Grant –  has led to new understanding of the parasite’s unusual life cycle, and how changes in water temperature and other environmental factors can cause it to proliferate.

The documentary, Saving Salmon, was scripted, directed and produced by Judith Jensen, director of Educational Solutions, a Klamath Falls nonprofit. Sea Grant videographer Steve Roberts contributed footage to the project, which is scheduled to air at 9 pm Feb. 7 on SOPTV.
