Meet Lisa Hiruki-Raring: Education and Outreach Coordinator for the Alaska Fisheries Science Center

May 19, 2021 — The following was released by NOAA Fisheries:

What is your key responsibility?  

I translate the research that our scientists do into educational activities or resources. I develop and foster partnerships between the Alaska Fisheries Science Center and other agencies and organizations. I believe education helps to strengthen relationships between communities and our scientists. It is a way to give back to the communities where we do research by sharing and exchanging information with students, families, and community members. We focus on all levels of education, from K-12 to undergraduate internships to graduate fellowship opportunities. We also do informal education opportunities to reach the general public.

What is your educational background?

I grew up and went to school  in Edmonton, Alberta, Canada. I have a Bachelor of Science degree in Computing Science, Scientific Applications, from the University of Alberta. I had initially wanted to study biology or zoology, but somehow got the idea that there weren’t many jobs in biology. So I studied computers instead, with a minor in biology/zoology. As an undergraduate, I volunteered at an international mammalogy conference held at my university. At the conference I met Dr. Ian Stirling, a polar bear biologist. I got the opportunity to work in his lab as a volunteer and later as a student technician.

He connected me with the Hawaiian monk seal research program at the NOAA Fisheries lab in Honolulu. That inspired me to pursue a Master’s degree in zoology, studying injuries in Hawaiian monk seals. I worked for the Pacific Islands Fisheries Science Center in Honolulu for a few years, studying population dynamics of Hawaiian monk seals. Then I moved to Seattle to work in the Alaska Fisheries Science Center’s Marine Mammal Laboratory. First I worked on Antarctic fur seals, and later on harbor seals and ice-associated seals in Alaska. Finally, I moved into education and outreach coordination.

Climate Change Raises Risk of Prey Mismatch for Young Cod in Alaska

April 9, 2021 — The following was released by NOAA Fisheries:

For a young Pacific cod, first feeding is a life-or-death moment. Cod larva are nourished by a yolk sac after they hatch. Once the yolk sac is depleted, they must find food within days in order to survive. If there is no prey available during that critical window for first feeding, young fish face starvation.

Warming Alaska waters are increasing the risk of prey mismatch and starvation for cod larvae, a new study finds.

NOAA Fisheries scientists collaborated with our partners to look at how temperature shifts affected first feeding Pacific cod larvae in two large ecosystems: the southeast Bering Sea and Gulf of Alaska. The models made predictions for 1998–2019, a period that encompassed warm and cool years, including a series of extreme heatwave events beginning in 2014.

“Warming can increase the metabolic demands of fish and shift the timing of their food production. So you have temperature unravelling the system, moving food around. And you have fish needing food now. When mismatched prey timing and increased metabolic demand line up, it can be pretty disastrous,” said Ben Laurel, NOAA Fisheries scientist at the Alaska Fisheries Science Center, who led the study. “The better we can understand and predict these effects, the more effectively we can manage them now and in the future.”

A Rising Tide Lifts All Fishers

April 1, 2021 — In the summer of 2013, a male captain was accused of raping and assaulting a female fisher multiple times during their week-long isolation in Prince William Sound, Alaska.

This horrific encounter points to a sobering problem for female fishers: the specter of sexual assault. Harassment and abuse aren’t necessarily more common in the fishing industry, but several factors make the situation on boats unique. For one thing, fishing involves spending weeks in a confined workplace, often in remote regions with no cellphone service. For another, many fishing vessels constitute their own small businesses, with no human resources department or codified policy that workers can turn to. And as with workers in other rural industries such as forestry and agriculture, who have fewer support systems to access than employees in urban areas, fishers tend to experience and grapple with abuse on their own.

That’s why Bristol Bay, Alaska, fisher Elma Burnham is asking her colleagues to sign a safety pledge that she created in 2017. To date, more than 500 captains, deckhands, processors, and tenders have signed the pledge, promising to uphold an understanding of consent and to work toward abolishing abuse in the industry; to intervene against harassment; to provide a safe place to work; and to pay, teach, and actively promote fishers who aren’t cisgender men.

Burnham grew up in an oystering family off Long Island Sound in Connecticut and now works as a Bristol Bay set-netter, fishing for sockeye salmon during the summer. She started developing her pledge after the 2016 US presidential election, which for her felt like a symbol of entrenched misogyny. She wanted to see what she could do on a local level, so she started Strength of the Tides, a group that brings female, transgender, and nonbinary fishers together to network, support one another, and ask for boat owners to sign the pledge. Although organizations like this are more common in commercial fishing, shipping, and other maritime sectors, says Burnham, they are rare to nonexistent in the world of small-scale fisheries.

Although Burnham says that she’s never faced harassment or abuse on the job, she knows “that’s not the case for everyone.”

Alaska Fisheries Science Center 2020 Year in Review

March 22, 2021 — The following was released by NOAA Fisheries:

The Alaska Fisheries Science Center was able to accomplish a lot in FY 2020 despite the need to cancel some important field research and fish, crab and marine mammal surveys due to the COVID-19 pandemic.

It was a year of perseverance, creative thinking, and flexibility.

Our scientists took major steps to adjust the way we do business, protecting staff, communities and research partners while delivering critical science to support resource management and conservation efforts in FY20-21.

Some Highlights:

  • Set up makeshift, home-based labs to conduct critical process studies to provide age and diet information to inform fish and marine mammal stock assessments.
  • Employed innovative technologies to collect and more efficiently analyze data safely (e.g., sea going and aerial drones, artificial intelligence, remote camera and underwater acoustic monitoring systems, and sophisticated camera systems that simultaneously collect color, infrared, and ultraviolet images, etc.)
  • Substantially overhauled standard operating procedures to work with fisheries observer provider companies to deploy Federal fisheries observers on fishing vessels and in seafood processing facilities to collect needed data so fisheries could continue to operate and provide seafood to the nation and the world throughout the pandemic
  • Designed new modeling approaches to estimate fish and crab abundance to account for data limitations due to some cancelled surveys and research activities
  • Provided critical socio-economic analyses of COVID-related impacts on the commercial and recreational fishing industries
  • Increased collaboration with research, co-management and industry partners to monitor and collect data safely for bowhead whales, humpback whales, harbor seals, gray whales, Steller sea lions, northern fur seals, California sea lions, and commercially valuable pollock, red king crab and sablefish
  • Organized and safely supported a major ecosystem survey in the Bering Sea and Chukchi Sea during the pandemic
  • Completed a successful environmental DNA (eDNA) proof of concept in the inshore waters around Juneau, AK
  • Enlisted the help of state and academic scientists, Alaska Indigenous communities, private companies and others to collect ecosystem information and provide critical context for resource management decisions this year

Water Clarity Study Sheds Light on Bering Sea Change

March 18, 2021 — The following was released by NOAA Fisheries:

In 2004, Alaska Fisheries Science Center biologists began attaching light sensors to Bering Sea survey bottom trawls to evaluate the effects of light on fish catchability. Fifteen years later, researchers looked at this unique dataset in a new light to reveal much more about the dynamic Bering Sea ecosystem.

NOAA Fisheries scientists collaborated with our partners to develop an automated process to translate these data into the first long time series of subsurface water clarity for the eastern Bering Sea.

“Until now, there was very little long term information on subsurface water clarity in the Bering Sea,”  said Sean Rohan, the NOAA Fisheries Alaska Fisheries Science Center biologist who led the study. “Working with the annual surveys provided unprecedented spatial coverage and resolution over a span of 15 years.”

Their approach provides a tool that expands possibilities for research in other regions. Their findings reveal patterns and trends in water clarity over depth and time that enhance our understanding of recent and future changes in the Bering Sea.

Preliminary Results of e-DNA Study Shows Promise for Improving Understanding of Nearshore Habitats for Fish and Crabs in Alaska

February 25, 2021 — The following was released by NOAA Fisheries:

Many marine fish and crab species spend their critical early development stages of life in shallow, coastal waters. Scientists at the Alaska Fisheries Science Center’s Auke Bay Laboratories conducted a pilot study using environmental DNA (eDNA) techniques in 2020. They identified more than 40 species in nine sites around Juneau, Alaska.

Every marine organism sheds small amounts of tissue and waste into the water. This material potentially contains eDNA from the source organism. Genetic analysis of the eDNA can help us to identify species and detect the diversity of species. It can also possibly determine the abundance of each species that have been present in the water sample even days after the organism has left the area. Environmental DNA can complement traditional surveys that are able to identify the age or size of a species.

The major objective of this study was to demonstrate that eDNA metabarcoding represents a feasible and cost-effective alternative to traditional sampling for collecting species diversity data and identifying Essential Fish Habitat (EFH). While eDNA has been used to assess biodiversity in many environments, it is important to verify the technique and compare it to data collected from traditional surveys to ensure that results are robust. This is especially important in dynamic environments such as those found in Alaska, where variables such as large tidal swings and severe weather can influence eDNA transport and detection.

“There are so many ways eDNA research can help us do our jobs better,” said Wes Larson, program manager, Genetics Laboratory. “We are able to detect a fish after it has left an area. It is also a less invasive means for sampling habitats that enables us to detect cryptic fish. Cryptic fish are fish that may not typically be sampled in traditional survey gear or may be a rare or low-density organism that surveys miss. Additionally, eDNA can help us detect important pelagic fish like cod and pollock that may be offshore and could avoid smaller nets. ”

NMFS reports fishing revenue crashed 29 percent in pandemic

January 19, 2021 — The U.S. fishing industry lost nearly one-third of its revenue in the first seven months of 2020 as the covid-19 pandemic vaporized its major markets, according to a new analysis by NMFS.

The year started on a high note, with revenues up 3 percent in January and February – before diving 19 percent in March and cratering at 45 percent less in July, said Paul Doremus, deputy administrator for operations at NMFS, in a telephone conference with reporters Friday.

Cumulatively, “over those seven months we’re looking at a 29 percent decrease,” said Doremus.

The agency mobilized its economic experts and government and academic partners in March to document the impact of the pandemic and begin preparing “as comprehensive an account as we could,” said Doremus.

The findings were compiled in a report with more than 100 pages of supporting documents, including detailed region-by-region breakdowns, by authors and economists Rita Curtis of the NOAA Fisheries Office of Science & Technology and Steve Kasperski of the agency’s Alaska Fisheries Science Center.

While the report only documents the industry’s situation up through July, “we’ve already initiated the work to do that next update,” said Curtis. The goal is to continue monitoring economic impacts and fishermen’s response, drawing lessons and strategies for making fishing communities more resilient, said Doremus.

Distribution and Abundance of Forage Fish in Arctic and Sub-Arctic Waters Affected by Warming Ocean Conditions

January 14, 2021 — The following was released by NOAA Fisheries:

Pelagic or forage fish species are an important source of food for marine predators in the eastern Bering Sea. This group of fish includes capelin, Pacific herring, juvenile chum salmon, juvenile pink salmon, juvenile sockeye salmon, and walleye pollock during their first year of life.

A new study by scientists at the Alaska Fisheries Science Center shows variable effects on species distribution and abundance. It looked at several warm periods from 2002–2018 when ocean temperatures were warmer than average for four or more consecutive years.

Previous studies by NOAA Fisheries documented a northward shift in age-0 pollock, juvenile salmon, herring, and capelin during the 2002-2005 warm period relative to the 2006-2011 cool period in the eastern Bering Sea.

“However, this is the first study to look at temperature-related changes in the distribution and biomass (total average weight of all fish) of pelagic fishes over multiple warm periods,” said Ellen Yasumiishi, researcher, Alaska Fisheries Science Center and lead author for the study. “Studies like this are also important for understanding factors that may affect juvenile salmon and age-0 pollock growth, development and ability to reach maturity. As adults these fish are targeted by commercial, recreational, and subsistence fisheries in Alaska.”

ALASKA: Some Fishermen on Edge After Rough Year in North Pacific

January 6, 2021 — Some fishermen in the North Pacific Ocean are on edge ahead of a traditionally fruitful winter fishing season, following a rough 2020 that saw catch rates fall below long-term averages.

The coronavirus pandemic forced the cancellation of some research surveys, making it more difficult to determine how many fish are in the Bering Sea off Alaska, the Seattle Times reported Monday.

The Seattle-based Alaska Fisheries Science Center canceled five of six research missions that help scientists measure fish stocks because of fears of virus outbreaks at sea.

Fishermen have begun their two-week coronavirus quarantines ahead of the Jan. 20 start of the fishing season and aren’t sure what they’ll find once ships largely based in Washington state make their way to the Bering Sea.

“This is the best time of year,” said Kevin Ganley, who captains a 123-foot (37-meter) boat called American Beauty. “If (the fish) are not there, we’re in trouble.”
