Ever wonder how to feed an octopus? Well, now you can find out–by watching How to Feed a Giant Pacific Octopus, a video produced by Oregon Sea Grant for NOAA’s Ocean Today kiosk.
The three-minute video features a very hungry Reuben the Octopus, along with Bill Hanshumaker, Oregon Sea Grant’s marine public education specialist at Oregon State University’s Hatfield Marine Science Center in Newport, Oregon.
The summer 2013 issue of Oregon Sea Grant’s magazine, Confluence, is now online at http://seagrant.oregonstate.edu/confluence
Articles in this issue, which focuses on aquaculture in Oregon, include “The Whiskey Creek Shellfish Acid Tests,” “Priced out of our own seafood,” and “The traveling ornamental defender.”
NOAA Fisheries highlights graduate researcher Noelle Yochum and her work with Oregon’s Dungeness crab fleet on bycatch reduction and crab mortality:
For popular seafood menu items like Dungeness crab, there’s good reason to make sure that there is a healthy supply to meet demand. That’s just what the Oregon C.R.A.B. Project is meant to do. This budding research partnership is looking for ways to improve the long-term sustainability of the state’s crab fishery while building relationships with the fishing industry and local community.
C.R.A.B., which stands for Collaborative Research to Assess Bycatch, is funded by NOAA Fisheries’ Bycatch Reduction Engineering Program and the Oregon Dungeness Crab Commission. Researcher Noelle Yochum from Oregon State University is collaborating with local commercial and recreational fishermen to tag female and small male crabs that are caught and thrown back because, by Oregon law, they cannot be sold. Through this research, Noelle hopes to capture estimates of survival rates for these crabs along with an understanding of potential ways to increase survival.
Noelle’s collaboration with Newport crab fishermen was the subject of our cover story in last summer’s edition of Confluence magazine. The crab bycatch collaboration is one of many outcomes of a long-term Oregon Sea Grant effort, led by coastal Extension Sea Grant specialists, to bring the fishing fleet and scientists together for mutual understanding and benefit.

Read more about the Symposium in Currents, the HMSC newsletter – now available via RSS feed – and while you’re at it, check out the redesigned HMSC Website.
The HMSC is celebrating its 47th year as a leading marine laboratory distinguished by its many collaborative research partnerships. Originally established as a marine laboratory for OSU, the center currently hosts research and education programs from seven OSU colleges and six state and federal agencies on a 49-acre campus. on the south shore of Yaquina Bay. The facility is also home to the HMSC Visitor Center, managed by Oregon Sea Grant as a public and K-12 education facility and a social laboratory for OSU’s Free-Choice Learning Lab.
LINCOLN City – More than 100 junior high, high school and college students will converge on the Lincoln Community Center this Saturday (May 4) to compete in the Oregon Regional Marine Advanced Technology ROV Competition – and a chance to advance to the international finals.
Teams from Albany, Astoria, Corbett, Corvallis, The Dalles, Eddyville, Lincoln City, Salem, Toledo, Portland and Waldport are expected for the competition which runs from 8:30 am to 4:30 p.m. at the community center, 2150 NE Oar Place. The event is open to the public.
Competing teams, ranging from 6th grade to college age, have designed and built tethered underwater robots known as remotely operated vehicles, or ROVs. The annual competition is sponsored by Oregon Sea Grant, the OregonCoast STEM Center, and the Oregon Chapter of the Marine Technology Society, and is intended to encourage Oregon students to learn and apply science, technology, engineering and math skills.
Full-scale ROVs are widely used in scientific research, ocean exploration, homeland security, the offshore oil and gas industry, and other industries. This year’s contest highlights the role ROVs play in the installation, operation, and maintenance of ocean observing systems, collections of high-tech instruments above and below the waves that provide around-the-clock information about what is happening in the ocean. Via fiber optic cable, the data collection equipment continuously communicates information to scientists, engineers and technicians who use it to understand and make predictions about the ocean, coast, and ocean resources. Ocean Observing Systems provide critical information on climate change, toxic algal blooms, tsunamis and other ocean hazards.
Competing teams must pilot their ROVs to perform a variety of underwater mission tasks, from installing a simulated power and communications “hub” and scientific instruments in order to complete a seafloor ocean observatory to removing bio-fouling organisms from instruments and performing maintenance on moorings.
The winning team will advance to the 12th annual MATE International ROV Competition, June 20-22 in Federal Way, Wash.
The regional MATE program, one of 22 such competitions around the world, is supported by local sponsors including the Marine Technology Society, the Oregon Coast Regional STEM Center, OSU’s Pre-College Programs, Northwest Aquatic and Marine Educators, the Siletz Tribe Charitable Funds, the Oregon Coast Aquarium, Pro-Build, Advanced Research Corporation, and the NOAA Officers Family Association. Local marine technology professionals volunteer as judges for the competition, evaluating the students’ ROVs, poster displays, and engineering presentations.
Scientists at Oregon State University’s Hatfield Marine Science Center are examining a handful of Japanese fish that may have survived a nearly two-year trip aboard a small fishing boat torn off the Japanese coast by the 2011 tsunami.
The fish – Oplegnathus fasciatus, known as Barred knifejaw or Striped beakperch – were found in the bottom of a Japanese boat that washed ashore at Long Beach, WA on March 22. The vessel is one of a growing number of large items cast to sea by the Japanese tsunami that have made their way across the ocean to Pacific Northwest shores.
Sam Chan, Oregon Sea Grant’s invasive species specialist, said the fish species normally are found only as far east as Hawaii. Scientists aren’t yet sure whether the fish traveled all the way from Japan, or if they somehow got onboard the derelict vessel as it crossed the ocean. “Either way, it’s an interesting case of organisms ‘rafting’ across the ocean,” Chan said.
OSU’s Jessica Miller, a marine fisheries ecologist with the HMSC-based Coastal Oregon Marine Experiment Station, as four of the fish and is examining their stomach contents and otoliths (specialized bones found in the ears of fish and other species) for insight into what the fish had been eating and the environmental conditions they encountered during their transit. The fifth fish is on display at the Seaside Aquarium.

NEWPORT, Ore. – Oregon State University’s Hatfield Marine Science Center invites public to explore its marine science labs and Visitor Center, “behind the scenes” on Saturday, April 13, when the Newport facility hosts its annual Marine Science Day.
The free event, which runs from 10 a.m. to 4 p.m., will feature scientists and educators from OSU, Oregon Sea Grant, federal and state agencies, Oregon Coast Aquarium, and the nearby NOAA Marine Operations Center-Pacific. It is a chance for the public to explore one of the nation’s leading marine science and education centers.
An full schedule of events is available at: hmsc.oregonstate.edu/marinescienceday
In addition to a varietyof marine science presentations, two research themes will be highlighted. One is the science behind bycatch reduction devices, which will be featured by researchers from NOAA Fisheries, Oregon Department of Fish and Wildlife, OSU, Pacific States Marine Fisheries Commission, and Foulweather Trawl, a Newport netmaker.
Marine Science Day visitors will see actual bycatch reduction devices and have an opportunity to view videos showing how fish are excluded or retained, depending on their size, swimming ability or other characteristic. Other research will highlight genetics or other tools used to distinguish between wanted and unwanted catch. Scientists will be on hand to answer questions and discuss their research.
“Visitors will learn not only about the problem of bycatch but also about the solutions, which range from simple and elegant to complex and cutting-edge,” said Maryann Bozza, program manager of the center. “All of the different HMSC research displays on bycatch reduction will be grouped together.”
A second theme will be wave energy, highlighting the efforts of the OSU Northwest National Marine Renewable Energy Center to improve and facilitate testing of wave energy devices and evaluate their potential effects on marine habitats. HMSC’s Sarah Henkel, a senior research assistant professor in the OSU Department of Zoology, will present an update of wave energy developments on the Oregon Coast.
Henkel’s talk begins at 3 p.m. in the Visitor Center auditorium.
Among other highlights of Marine Science Day:
A number of educational activities for children and families will be available, presented by Oregon Sea Grant, U.S. Fish and Wildlife Service and the Oregon Coast Aquarium.
The OSU Hatfield Marine Science Center is located at 2030 S.E. Marine Science Drive in Newport, just south of the Highway 101 bridge over Yaquina Bay.
NEWPORT – Dan Bottom, fisheries biologist with NOAA’s Northwest Fisheries Science Center, steps up to the bar to talk about salmon at the next Science on Tap event on March 13 at Brewer’s on the Bay.
“Celebrating Diversity: Sustaining Pacific Salmon in a Changing World” is Bottom’s theme for the evening, which takes place in the downstairs Board room at Rogue Ale’s South Beach waterfront location. Doors open at 5:30 p.m. and the talk begins at 6; the event is free and open to the public. Appetizers will be served, and additional food and drinks available for purchase from the menu.
Bottom, editor and contributing author for Oregon Sea Grant’s 2011 book Pathways to Resilience: Sustaining Pacific Salmon in a Changing World, will discuss the importance of salmon diversity and the attributes of resilience. His talk will draw from the book’s 11 peer-reviewed articles, including case studies of salmon and salmon fisheries, and will explore management actions that draw on salmon life history and genetic diversity to maintain salmon populations into the future.
Bottom notes, “Salmon exhibit a wide variety of life history traits. These include salmon runs and populations that exhibit differences in migration timing, duration of estuary rearing and size when the salmon enter the ocean.” Healthy, diverse watersheds, says Bottom, provide habitat connections that not only sustain diverse salmon life histories but also provide diverse social and economic opportunities for people.
The 392-page, full-color book, with a prologue by Governor John Kitzhaber, will be available at the event for purchase and author signing. It can also be purchased online from Oregon Sea Grant.
Science on Tap is a regular program of OSU’s Hatfield Marine Science Center, co-sponsored by Oregon Sea Grant, NOAA, the Pacific States Marine Fisheries Commission, MidCoast Watersheds Council, Native Fish Society, and The Wetlands Conservancy.

This clever video uses a catchy rap tune, a wise-cracking puppet and some simple, practical instructions to engage fishermen in protecting rockfish from dying of barotrauma, by reaching them how to return their excess catch to the deeps – alive.
Barotrauma results when a rockfish is caught and hauled rapidly to the surface and its internal, air-filled swim bladder expands, often causing the animal’s eyes to bulge and even pushing its stomach out of its mouth. If thrown back in the water, the inflated bladder can cause the fish to float, making it easy prey for seabirds and other hungry animals.
But if the animal can be returned to the deeps quickly, water pressure will often reverse the expansion, allowing the fish to survive. The video demonstrates a number of effective tools – home-made and commercial – for getting the fish back to the bottom quickly and with as little harm as possible.
The video, funded in part by California Sea Grant, was produced by a team including Alena Pribyl, a NOAA Southwest Fisheries Science Center researcher who earned her PhD. at Oregon State University while studying barotrauma.
After years at sea, sockeye salmon returning to their freshwater homes may be guided by an early memory of the Earth’s magnetic field, encoded at the site where natal streams empty into the Pacific Ocean, according to a an Oregon Sea Grant-supported study published today in Current Biology.
Oregon State University’s Nathan Putnam and David Noakes, along with researchers from the University of North Carolina Chapel Hill, the University of Washington, and the University of California Davis, pored over 56 years of dta from federal fishery scientists who tracked the movements of salmon at the mouth of British Columbia’s Fraser River, where fish must choose to swim north around Vancouver Island, or around to the south. They matched that data with measurements of the Earth’s geomagnetic field, which shifts predictably in strength and orientation over time and found that fish tended to choose the path where the field strength was more similar to that of the river mouth when they’d left, two years before.
Scientists hope the finding will help solve the mystery of how salmon find their way back to the rivers of their birth across thousands of miles of ocean. It’s already accepted that in the final stages of the journey to their breeding grounds, salmon use odors to guide them back to the stream or inlet where they hatched. But how the fish find their target river remains a mystery, although scientists have suspected for a while that magnetic cues play a role. Last summer, a team including UNC-Chapel Hill researcher Kenneth Lohmann – also part of this study – reported that rotating magnetite crystals in a fish nose responded to magnetic field orientation, providing a possible biological mechanism for magnetic field tracking.
The OSU researchers hope to further investigate the magnetic field correlation by subjecting captive fish to artificial magnetic fields and studying their behavior.
