CORVALLIS, Ore. – A survey of professionals in jobs related to Extension and aquaculture at universities and two federal agencies found that over half plan to retire in the next 10 years. The finding comes as the U.S. government ramps up its funding for research on farming fish, shellfish and seaweed.

Extension is a university-based, nationwide program that provides research-based information, educational opportunities, and technical expertise to help people, communities and businesses solve problems and be successful. Its aquaculture experts – including those with the national Sea Grant program – have expanded markets, trained workers on using new technologies, informed consumers about the nutritional benefits of seafood, and analyzed the economics of raising certain species.

The survey was conducted by faculty with Oregon Sea Grant, Kentucky State University (KSU) and the University of Idaho (U of I). It was sent to about 160 people in the United States who attended the 2017 National Aquaculture Extension Conference, are on an aquaculture Extension listserv with the U.S. Department of Agriculture (USDA), or are on a fisheries Extension listserv with the National Oceanic and Atmospheric Administration’s (NOAA) Sea Grant program.

“We pretty much covered the entire population of people in the U.S. who either work for Extension and have some aspect of aquaculture in their jobs or who hold administrative or other positions that support Extension staff involved with aquaculture,” said Sam Chan, a watershed Extension specialist with Oregon Sea Grant who helped conduct the survey.

Sixty-nine people responded to the survey. About two-thirds said they are Extension aquaculture specialists or educators. The remainder largely described themselves as “working in a related field.”

Sixty-six people responded when asked how much longer they plan to work in their current position before retiring. A third said one to five years, and 20% said six to 10 years. That means that over half of the respondents could retire in the next 10 years. If that were extrapolated to the estimated total workforce of aquaculture Extension professionals and related administrators, Chan said, it would mean that over 80 people are planning to retire in the next decade.

“Given the number of upcoming retirements, the window is becoming increasingly narrow for current aquaculture Extension specialists to recruit, train and mentor new professionals,” said Chan, who is a member of the National Aquaculture Extension Steering Committee and is based at Oregon State University.

To attract new hires, Chan said, respondents suggested that universities emphasize the variety of professional backgrounds that a career in aquaculture Extension can use. For example, he said, knowledge of law, engineering, food science, economics and environmental science can be useful to Extension specialists who work in aquaculture.

The survey asked people if they thought their institution or agency would refill their position with aquaculture Extension duties. Forty-four percent of the 68 respondents said yes and 46% said maybe.

The survey also asked about age. Fifteen percent of the 64 people who responded to that question said they were at least 67 years old. Forty-five percent were 51 to 66 years old, and 34% were 36 to 50 years old. About a quarter of the 64 respondents were women, with a majority of the women between 36 and 50 years old.

Sixty-seven people responded when asked how long they have worked in aquaculture Extension. Nearly half said they have worked in such a role for 16 to 31 or more years. Nearly 30% said no more than five years.

The survey comes at a time when the federal government is working to grow the U.S. aquaculture industry by funding research and trainings. In October 2017, NOAA said it would award $9.3 million to 32 projects to support U.S. aquaculture. The next year, NOAA announced 22 additional grants totaling $11 million, also to advance U.S. aquaculture.

“Growth in the domestic aquaculture industry holds great promise to create jobs and reduce our dependence on seafood imports,” Secretary of Commerce Wilbur Ross said at the time of the 2018 announcement.

Forrest Wynne and Gary Fornshell, aquaculture Extension specialists at KSU and the U of I, respectively, helped conduct the survey.

OSU gets two NOAA aquaculture grants to help oyster industry and marine fish hatcheries

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.
