Invasive plant poses threat to Alaska sockeye salmon

November 22, 2019 — An invasive, quick-spreading aquarium plant could forewarn of the upcoming difficulties that Alaska salmon runs may face as marine environments change from human intervention.

The plant is elodea, which is native to the lower 48 U.S. states and is commonly used in aquariums. Researchers say it was first dumped into Alaska waters in the early 1980’s with the unwanted contents of an aquarium and has since adapted to colder water. Now, it is being transported from lake to lake by float planes and growing at an alarming rate of speed.

Program aims to provide Alaska Native and rural students with opportunities at NOAA

September 13, 2019 — The following was released by the University of Alaska Fairbanks:

Alaska Sea Grant is partnering with NOAA Fisheries to provide opportunities to Alaska Native and rural students at the federal agency. The goal is to increase their representation in marine-related professions at NOAA Fisheries, an arm of the National Oceanic and Atmospheric Administration formerly known as the National Marine Fisheries Service.

During summer 2019, NOAA Fisheries and the University of Alaska Fairbanks, which houses Alaska Sea Grant, launched a marine education and workforce development program that brought five undergraduate students to the UAF campus for a two-week course run by Vladimir Alexeev, research professor at the International Arctic Research Center. It’s called the Partnership in Education Program Alaska. The program was developed by policy analysts Sorina Stalla and Megan Hillgartner and by UAF faculty member Alexeev.

This summer’s curriculum focused on marine sciences and the drivers of Arctic change, climatology, oceanography, marine resource management and policy, law, subsistence use and perspectives, hydrology, climate modeling, permafrost, interior wildfires, meteorology, atmospheric science and more. Following their course work and a trip to the Toolik Field Station on the North Slope, students applied their knowledge and completed internships with NOAA’s regional Alaska office and its Alaska Fisheries Science Center in Juneau.

Global Ocean Acidification Research Starts at Local Level All Around the World

September 10, 2019 — SEAFOOD NEWS — Ocean acidification (OA) is a shift in the world’s oceans from neutral to more acidic water from the update of increasing carbon dioxide in the atmosphere. The ocean absorbs about 30% of the carbon in the air, resulting in increasing levels of carbonic acid in the sea.

Researchers in Alaska, the South Pacific, New England, and further afield are studying the effects of increasing OA on their waters. In Alaska, research is focused on fisheries — from the billion-dollar groundfish resource in the Bering Sea to life-saving subsistence food along coastline; in New England, Martha’s Vinyard oyster ponds are being protected locally as OA increases, and in the South Pacific, a recent gathering of environmental ministers announced new alliances on research for OA, including a brand new Pacific Climate Change Centre (PCCC) to address OA among other climate change impacts, research, and innovation in creating resiliancies among Pacific Nations.

Alaska ranks as the fastest-warming U.S. state, and because it is surrounded by cold oceans, it is experiencing the fastest rise in OA.

The Alaska Ocean Acidification Center connects scientists with stakeholders who want to know everything they can about how OA may affect the state’s valuable fisheries resources. Established in 2016, the Center tracks the latest carbon dioxide levels in the atmosphere (as of March 30, at 412.48 ppm, the highest recorded ever) and conducts experiments that inform what higher OA will do to pollock, cod, and crab species.

Robert Foy, Science and Research Director for NOAA’s Alaska Fisheries Science Center, says the direct effects of OA may be to reduce growth rates of juvenile fish, decreasing survival. OA can also interfere with sensory signals in the brain causing the fish to not recognize predators or prey. Indirect effects on the food web may reduce abundance of prey for fish, such as pteropods, the main food for juvenile fish. Cumulative effects may be a reduction in the overall productivity of fish resulting in less to catch commercially or gather for subsistence.

The Alaska Marine Advisory Sea Grant program supports the research of University of Alaska Fairbanks assistant professor Amanda Kelley, a top researcher on ocean acidification’s effects in Alaska. Alaska Sea Grant has funded Kelley’s research studying how shellfish react to different levels of OA. Sea Grant recently produced a video of work Kelley is doing in Seward and in Kachemak Bay to better understand OA and how tribal members and citizen scientists are getting involved in monitoring it.

After Alaska, Rhode Island ranks as the fastest-warming state, following by New Jersey, Connecticut, Maine, and Massachusetts. The oyster industry in Martha’s Vinyard has been monitoring OA for years and may have an innovative approach to mitigating it.

The Martha’s Vineyard Shellfish Group launched a shell recycle program, where they collect shells, let them age until they’re clean, and release them back into Great Ponds for restoration. “Adding shells helps buffer the water in small scales,” Emma Green-Beach, lead scientist of the Group said. “It provides hard calcium for baby oysters.”

Oysters are a “keystone species” on Martha’s Vineyard, as their existence provides a habitat for other organisms. “When you have clusters of oysters, they make huge reefs where fish, urchins, crabs, and all sorts of plants and animals can live,” Green-Beach said. “Little fish can hide there. Big fish can hunt there. Oysters create a hard and complex structure on an otherwise muddy, flat bottom.” Oysters also filter water, and adults can filter up to 50 gallons a day, according to Green-Beach.

The work that is being carried out in the Pacific to address this issue was highlighted at a side event during the second day of the Secretariat of the Pacific Regional Environment Programme (SPREP)’s 29th Meeting of Officials taking place in Apia, Samoa last week.

Among those highlighted was work of the New Zealand-Pacific Partnership on Ocean Acidification (NZPPOA) project in Fiji and Tokelau, Samoa’s joint initiative on OA monitoring with the Republic of Korea, and the recently published “Mainstreaming Ocean Acidification into National Policies” handbook on OA for the Pacific.

The NZPPOA project is a collaborative effort between the University of the South Pacific, the Pacific Community and SPREP, with funding support from the Ministry of Foreign Affairs of New Zealand and the Government of the Principality of Monaco. It aims to build the resilience of Pacific island communities to OA and was developed in response to needs identified during the Third United Nations Small Islands States Conference in Apia in 2014.

Its focus is on research and monitoring, capacity and awareness building, and practical adaptation actions. The pilot sites for the practical adaptation actions were Fiji, Kiribati, and Tokelau, two of which were present at the side event this afternoon and presented on the progress of the work being done in their countries.

OA monitoring buoys have been set up and deployed successfully in Palau, and will soon be set up in Samoa, and staff of the Ministry of Natural Resources and Environment in Samoa will have the responsibility to operate and maintain these buoy systems.

Blooms, beasts affected as Alaska records hottest month

August 19, 2019 — Alaska has been America’s canary in the coal mine for climate warming, and the yellow bird is swooning.

July was Alaska’s warmest month ever, according to the National Oceanic and Atmospheric Administration.

Sea ice melted. Bering Sea fish swam in above-normal temperatures. So did children in the coastal town of Nome. Wildfire season started early and stayed late. Thousands of walruses thronged to shore.

Unusual weather events like this could become more common with climate warming, said Brian Brettschneider, an associate climate researcher at the University of Alaska Fairbanks’ International Arctic Research Center. Alaska has seen “multiple decades-long increases” in temperature, he said.

Locked in and off-loaded: Quotas stifle diversity and stability in fishing

July 25, 2019 — As any commercial fisherman knows, fishing is a risky business. Fluctuations in markets, regulations, fish populations and the weather — not to mention the climate’s growing volatility — can result in fluctuating income that can threaten a fisherman’s livelihood.

Buffering against these fluctuations might mean taking a page from another risky business: the stock market.

A growing body of research is showing that, in most cases, fishermen are more likely to have stable year-to-year incomes if they diversify their fishing portfolios, much like an investor would diversify a stock portfolio, giving them a safety net to weather whatever the year brings.

“It can really pay for fishermen to diversify,” said Anne Beaudreau, a fisheries professor at the University of Alaska Fairbanks.

But there’s a surprising and troubling hitch to the promise of diversification. Alaskan fishermen are trending in a different direction — fewer people are fishing, and they are fishing fewer types of fish.

ALASKA: Study pinpoints trend toward fisheries specialization

May 10, 2019 — Commercial fishermen in Alaska have gotten older in the past three decades. As it turns out, they’ve become more specialized, too.

Fewer permits overall are in the water; between the early 1990s and 2014, commercial fishing permits in Alaska decreased by 25 percent. On top of that, fewer individual fishermen are moving between fisheries.

From 1988-2014, the number of individuals holding multiple permits declined from 30 percent to 20 percent, according to a study published in the journal Fish and Fisheries.

The bottom line: fishermen are increasingly putting all their economic eggs into one basket, and that makes them more vulnerable to the ups and downs of fishing.

The study was born out of a workgroup that met through the National Center for Ecological Analysis and Synthesis at the University of California Santa Barbara, said co-author Anne Beaudreau, an associate professor of fisheries at the University of Alaska Fairbanks.

The original intent was to study the long-term effects of the 1989 Exxon Valdez oil spill, but the data on fisheries specialization arose out of that work, she said.

“As we worked on this, we realized there are so many things that have caused long-term changes in the Gulf of Alaska; in the fisheries, it’s really hard to see the long-term effects of the oil spill,” she said. “A lot of the focus of the working group was on the biological effects … this paper sort of came out of the end of that.”

Study: Fishery consolidation in Alaska leaves fishermen vulnerable

May 9, 2019 — Alaskan commercial fishermen are specializing more and more, leaving them more vulnerable to the immense uncertainty fishermen have to contend with, according to a new study.

Targeting a diverse array of fish types in different regions can allow fishermen to weather the ups and downs instigated by fish population changes, new regulations, deflating markets and environmental disasters. But fishermen in Alaska are increasingly specializing. Fewer fishermen are on the water than three decades ago, and those who remain are participating in fewer fisheries, according to the study, which was published in Fish and Fisheries.

“Across different fisheries and regions of Alaska, there are fewer people fishing than there used to be and their fishing portfolios have become less diverse,” Anne Beaudreau, the lead author of the study and an associate professor at the University of Alaska Fairbanks, told SeafoodSource.

Individual fishery quota systems, plus the high cost of permits and other institutional barriers, have made it more difficult for new players to enter Alaskan fisheries, according to the study.

Though fishermen could, in theory, diversify their portfolio of permits, those management restrictions and high costs often prevent them from doing so, leading to more specialization. Permits can cost hundreds of thousands of dollars depending on the fishery, Beaudreau said.

Overlooked jellyfish play big role in Gulf of Alaska

April 15, 2019 — “Jellyfish have superpowers,” assured Heidi Mendoza-Islas, a graduate student at the University of Alaska Fairbanks College of Fisheries and Ocean Sciences.

The voracious carnivores will eat almost anything that fits into their mouths. When conditions are good, they grow fast and multiply. When conditions aren’t ideal, baby jellies can transform into cysts and wait it out.

So it is no surprise that jellyfish have been successful predators in the Gulf of Alaska, Mendoza-Islas said. But few studies have focused on the role jellyfish play in the Gulf’s ecosystem or how jellyfish affect commercially important finfish, such as pollock. Mendoza-Islas wants to change that.

Pace of Bering Sea Changes Startles Scientists

April 15, 2019 — The Yupik Eskimo village of Kotlik on Alaska’s northwest coast relies on a cold, hard blanket of sea ice to protect homes from vicious winter Bering Sea storms.

Frigid north winds blow down from the Arctic Ocean, freeze saltwater and push sea ice south. The ice normally prevents waves from forming and locks onto beaches, walling off villages. But not this year.

In February, southwest winds brought warm air and turned thin sea ice into “snow cone ice” that melted or blew off. When a storm pounded Norton Sound, water on Feb. 12 surged up the Yukon River and into Kotlik, flooding low-lying homes. Lifelong resident Philomena Keyes, 37, awoke to knee-deep water outside her house.

“This is the first I experienced in my life, a flood that happened in the winter, in February,” Keyes said in a phone interview.

‘Extreme’ lack of sea ice and autumn heat marked Alaska weather in 2018

January 2, 2019 — A stunning shortage of Bering Sea ice in spring and record warmth in autumn marked what scientists say will be one of the warmest years recorded in Alaska, raising questions about everything from the future of commercial fishing to new agricultural opportunities.

Alaska’s most “extreme” 2018 climate event was the lack of Bering Sea ice, growing only to half its previous lowest size, in 2001, said Rick Thoman, a climatologist with the University of Alaska Fairbanks.

That had consequences in Western Alaska coastal communities, causing winter flooding in villages usually ringed by protective sea ice, and raising risks for people hunting on iffy ice, or by boat instead of snowmachines.

“It is absolutely unprecedented,” said Thoman. “We’ve seen nothing like it” in records extending from modern satellite data back to whalers’ logs in the 1800s.

The limited ice, coupled with high sea surface temperatures and a mildly warm atmosphere, ensured that 2018 will be one of the five warmest years in Alaska history. The state averaged about 30.1 degrees statewide, Thoman said, based on a preliminary estimate.

It will mean the four warmest years in the state have been recorded in the last five years, with 2002 being the only outlier, he said. 2016 was the warmest-ever year for Alaska, at 31.9 degrees, based on records back to 1925.
