The National Oceanic and Atmospheric Administration (NOAA) has awarded scientists at Oregon State University two aquaculture grants that aim to make oysters safer to eat and help hatcheries feed certain marine fish more efficiently.

The first project, funded at $150,000, aims to reduce bacteria known as Vibrio parahaemolyticus in oysters without altering their texture and consistency. Researchers plan to add naturally occurring marine probiotics, which are live or freeze-dried microbial supplements, to the seawater in depuration tanks. Depuration tanks are where oysters are sometimes held to flush out contaminants that may be in their tissues. Researchers have already isolated various marine probiotics that inhibit the growth of pathogens.

The researchers also aim to develop a dipstick containing antibodies to quickly screen adult oysters for V. parahaemolyticus. The idea is that people would not need special training or equipment to use this diagnostic tool.

The leader of this two-year project is Shelby Walker, the director of Oregon Sea Grant, although the actual research will be conducted by the lab of Claudia Hase, a professor with OSU’s College of Veterinary Medicine. Partners include mAbDx, an immunodiagnostics company in Eugene, Ore.; and Reed Mariculture near San Francisco.

The other grant, worth $629,000, aims to improve the nutritional value of live prey fed to California halibut, California yellowtail and southern flounder. When they’re still in their larval stage, farmed saltwater fish are typically fed tiny rotifers and brine shrimp. However, these organisms are less nutritious than copepods, which are the natural prey of many marine fish in the wild. Given this, the researchers plan to feed rotifers and brine shrimp vitamin C and taurine, an amino acid. To make sure these nutrients don’t dissolve in the seawater, the researchers will encapsulate them in bubble-like liposomes, which can have impermeable membranes.

The researchers plan to:

  • determine the optimal concentrations that should be used for taurine and vitamin C,
  • evaluate how these nutrients affect the growth, survival and stress resistance of the fish,
  • develop methods to produce the liposomes on a larger scale instead of just at the laboratory level,
  • study how long-term storage affects how the liposomes retain the nutrients, and
  • determine how much it would cost to produce and store liposomes and how many liposomes would be needed to feed a certain amount of prey.

Walker will lead the three-year project, but the research will be conducted by the lab of Chris Langdon, a professor with OSU’s Department of Fisheries and Wildlife, and well as by staff at the subcontracted Hubbs-SeaWorld Research Institute in San Diego. Partners include the Texas Parks and Wildlife Department and Reed Mariculture. Bill Hanshumaker, a marine educator with Oregon Sea Grant Extension, will be involved with outreach activities.

Oregon Sea Grant will administer the funding for both projects. They are part of 32 grants totaling $9.3 million awarded by NOAA last week to further develop the nation’s marine aquaculture industry.

“This country, with its abundant coastline, should not have to import billions of pounds of seafood each year,” said Secretary of Commerce Wilbur Ross. “These grants will promote aquaculture projects that will help us reduce our trade deficit in this key industry.”

All projects include public-private partnerships and will be led by university-based Sea Grant programs.

“Industry is working alongside researchers on each of these projects, which will help expand businesses, create new jobs and provide economic benefits to coastal communities,” said Jonathan Pennock, the director of NOAA Sea Grant.

NOAA received 126 proposals requesting about $58 million in federal funds.

UO study moves seafood industry closer to farming gooseneck barnacles

Posted by: | October 13, 2017 Comments Off on UO study moves seafood industry closer to farming gooseneck barnacles |

10/13/17

A study led by a University of Oregon marine biologist has moved the seafood industry one step closer to farming gooseneck barnacles, which are a pricey delicacy in Spain and a common sight on the West Coast.

Funded by Oregon Sea Grant, researchers found that juvenile gooseneck barnacles in a lab grew at rates comparable to those of their counterparts in the wild.

Led by Alan Shanks, a professor with the UO’s Charleston-based Oregon Institute of Marine Biology (OIMB), the researchers glued juveniles to textured, acrylic plates hung vertically inside 12 plastic tubes that were about twice the height and diameter of a can of tennis balls. Unfiltered seawater was pumped in, vigorously aerated and allowed to overflow. After a week, the barnacles began secreting their own cement.

Twice a day for eight weeks, the researchers fed the barnacles either micro-algal paste or brine shrimp eggs; a third group of barnacles was not fed anything but was left to filter food out of the seawater. Once a week the researchers measured the barnacles’ growth. Those that were fed the brine shrimp eggs outgrew the other barnacles.

“The experiment has demonstrated that feeding is not dependent on high water velocities, and barnacles can be stimulated to feed using aeration and will survive and grow readily in mariculture,” Shanks said.

He added that unlike high-flow systems, his low-flow “barnacle nursery” doesn’t use as much energy or have expensive pumps to maintain, so it has the potential to decrease operating costs.

Despite the findings, the researchers are cautiously optimistic.

“While our experiment showed promise, there is still a great deal of research which needs to be done to solve some of the barriers to successful and profitable mariculture,” said research assistant Mike Thomas. “For example, inducing settlement of gooseneck barnacle larvae onto artificial surfaces has historically proven difficult and this makes the implantation of barnacles a laborious task. There are other methods of mariculture which need to be explored further for their efficacy before deciding on the best method.”

Another part of Shanks’ project involved conducting field research to see if there are enough gooseneck barnacles in southern Oregon to sustain commercial harvesting. The Oregon Department of Fish and Wildlife allows commercial harvesting of gooseneck barnacles on jetties but not on natural rock formations. Shanks hopes the agency will be able use the results of his work when regulating their harvesting.

Researchers used photographs and transects to estimate the barnacle populations on eight jetties in Winchester Bay, Coos Bay, Bandon, Port Orford, Gold Beach and Brookings. They estimated that there are roughly 1 billion adult and juvenile gooseneck barnacles attached to these eight jetties but only about 2 percent are of commercially harvestable size.

“Our surveys suggest that wild populations are unlikely to sustain long-term commercial harvest should the market significantly expand beyond its current size,” researcher Julia Bingham wrote in a report about the project.

She added that with the exception of jetties in Coos Bay and Winchester Bay, the other six jetties had such limited numbers of barnacles that even a “very small-scale harvest” – about 500 pounds per year per jetty – could wipe out harvestable-sized goosenecks on them in five years.

With a second round of funding from Oregon Sea Grant that was awarded in 2017, Shanks and Aaron Galloway, an aquatic ecologist at the OIMB, are continuing the research. Their new work includes:

  • studying how long it takes for a population to return to pre-harvest densities
  • testing different glues and surfaces to see if harvested barnacles that are too small for market can be reattached to plates and returned to the ocean
  • testing out bigger tubes for rearing barnacles in the lab to make them feasible for larger-scale aquaculture
  • testing other diets, including finely minced fish waste from a seafood processing plant

Summer 2017 “Shop at the Dock” tours in Newport and Warrenton show consumers how to buy in-season seafood

Posted by: | July 17, 2017 Comments Off on Summer 2017 “Shop at the Dock” tours in Newport and Warrenton show consumers how to buy in-season seafood |

Have you ever wanted to buy seafood right from the boat, but weren’t sure what questions to ask or what to look for? Have you ever stood at a seafood market staring at all the choices but not been sure what was local or in season?

If so, this summer is your chance to learn more about buying seafood. Experts with Oregon Sea Grant and the Oregon State University Extension Service will demystify the process during free, guided dockside tours in Newport and Warrenton that connect seafood lovers with commercial fishermen.

Oregon Sea Grant and Extension have been offering the tours – called Shop at the Dock – every summer in Newport since 2014, but this is the first year the event has expanded to Warrenton. During the tours, participants learn what seafood is in season, how it’s caught, whether it’s sustainable, and how to identify and buy high-quality fish and shellfish. Last year, the tours drew more than 350 people, said Kaety Jacobson, an Oregon Sea Grant marine fisheries specialist with Oregon State University’s Extension Service.

Dates for the remaining Newport tours are July 21 and 28, and Aug. 4, 11 and 18, 2017 with groups departing from dock 5 at 9:30 a.m., 10 a.m., 10:30 a.m. and 11 a.m. each day. The 90-minute tours are free and on a first-come, first-served basis. In Newport, registration is required only for groups of five or more by calling 541-574-6534 ext. 57427.

In Warrenton, the remaining tours will take place Sept. 15, 2017, at 9 a.m. and 11 a.m. and will include a tour of the Skipanon Brand Seafood cannery. Participants will also learn where they can find locally caught fish in local markets. Tours will start at the Warrenton Marina near the harbormaster’s office at 550 N.E. Harbor Place. For the Warrenton event, registration by phone is required for everyone and is on a first-come, first-served basis. To register, call 503-325-8573.

At both sites, participants are advised to wear comfortable walking shoes with traction, arrive 15 minutes early, and bring cash and a cooler with ice. For disability accommodations, please call the numbers above.

Barnacles for dinner? Could be!

Posted by: | August 4, 2016 Comments Off on Barnacles for dinner? Could be! |

gooseneck barnaclesIn Spain, a plate of gooseneck barnacles will set you back more than the cost of a lobster dinner. Known as percebes, goosenecks “set the palate in ecstasy,” a Barcelona chef recently told a reporter. Nevertheless, Julia Bingham winced a little last spring when asked if she had ever tried the tube-shaped delicacies while she was studying them as an undergraduate at Oregon State University.

“I get that question a lot, and it kills me to say ‘no,’” said Bingham, who had gingerly navigated the wave-tossed shore of Cape Perpetua to collect barnacle samples for her University Honors College thesis. “It’s supposed to be sweeter than crab or lobster and taste like the ocean.”

“Shop at the Dock” in 2016 for fresh seafood, fisheries education

Posted by: | July 11, 2016 Comments Off on “Shop at the Dock” in 2016 for fresh seafood, fisheries education |

July 11, 2016

NEWPORT – What started as an experiment to help bring new customers to fishermen who sold seafood off their vessels has quickly become a favorite summer activity for a growing number of locals and visitors in Newport.

shop-the-dockSponsored and run by Oregon Sea Grant in partnership with the Port of Newport, “Shop on the Dock” in 2016 is entering its third summer of offering free, guided educational tours of Newport’s commercial fishing docks. Shoppers learn a bit about the fisheries, meet the people who catch the fish, and have an opportunity to buy the freshest salmon, tuna, halibut and crab, usually at prices lower than they’d find at their local supermarkets.

The summer of 2016 will see more walks spread over two months – July 15, 22 and 29, and Aug. 5, 12 and 19 – and having multiple walks (at 9:30 a.m., 10 a.m., 10:30 a.m. and 11 a.m.) each date.

“It’s like going down to the docks with a friend who knows the seafood – and knows the fishermen,” said Kaety Jacobson, Sea Grant’s Newport-based Extension fisheries specialist, who runs the program. “We make it easy for people.”

Kaety and tunaNEWPORT – Kaety Jacobson, Oregon Sea Grant fisheries specialist, is packing her bags – and then some – for a trip to the nation’s capital to take part in the 41st annual NOAA Fish Fry.

Thanks to a donation from the Oregon Albacore Commission, Jacobson will travel with 250 lbs of fresh-frozen albacore tuna loin portions – and a recipe for tuna poke, a Hawaiian-style marinated tuna salad, courtesy of Newport’s Local Ocean Seafoods restaurant.

The Fish Fry, a popular summer event sponsored by the National Oceanic and Atmospheric Association runs Wednesday, June 8th from 6pm – 9pm at the Herbert C. Hoover Main Commerce Building on 14th St. and Constitution Avenue.  The event promotes public understanding of aquaculture and sustainable marine fisheries.

Sea Grant programs from around the country were invited to take part during our 50th anniversary year to showcase the variety of sustainable seafood from in the nation’s ocean and Great Lakes states.
