FIS looks to satellite tech for new opportunities to elevate Scottish seafood

April 21, 2021 — As part of its strategy to advance the sustainability and prosperity of Scottish fisheries, Fisheries Innovation Scotland (FIS) has commissioned Edinburgh, Scotland-based company Space Intelligence to conduct “blue sky” research into the potential benefits of utilizing satellite technology within the sector.

With Space Intelligence specializing in Earth observation and transforming satellite data into actionable information, the project will encompass a “pioneering review” of the role that satellite technology could play in supporting Scottish fisheries, FIS said, adding that this is the first time that a satellite technology company has supported the sector in this way.

ALASKA: Glacier Bay’s Alsek River predicted to shift course within a few decades due to climate change

April 16, 2021 — New research indicates that the Alsek River will change course dramatically over the next few decades. Geologists with the National Park Service predict that glacial retreat related to climate change may move the mouth of the river 20 miles away from its current location. This could pose challenges for raft trips and fishing in Glacier Bay National Park.

The Alsek River originates in the Yukon Territory and flows hundreds of miles south before emptying into the Pacific Ocean at Glacier Bay National Park. Near the end of its journey, the river widens into Alsek Lake. It’s currently separated from the Grand Plateau Lake by a glacier.

But when that glacier melts enough, the lakes will combine and eventually drain into the ocean down a steep embankment.

Michael Loso is a Park Service geologist who researches the Alsek changing course.

“Presently, the Alsek River can’t get there because this glacier, you know, this big pile of ice is in the way,” Loso said. “But really, the thrust of our paper is to make the case that once that glacier ice completely goes away, by a combination of melting and calving into the two lakes, you would be able to paddle your raft right on over to Grand Plateau Lake because the two lakes would be combined.”

ALASKA: Kodiak Fisheries Adjust to Tariffs, Pandemic and Climate Change

April 15, 2021 — For the first time in 20 years, China is not a viable market for U.S. seafood suppliers due to increased tariffs between the two countries, as well as complications caused by the COVID-19 pandemic. This uncertainty has raised concerns among Kodiak processors, harvesters and industry leaders.

In an effort to keep processors working, the trawl industry had requested that the rockfish season begin on April 1, one month earlier than is typically authorized.

Study of US tuna fisheries explores nexus of climate change, sustainable seafood

April 14, 2021 — A new study published in Elementa by researchers at the University of California, Santa Cruz and NOAA examines traditional aspects of seafood sustainability alongside greenhouse gas emissions to better understand the ‘carbon footprint’ of U.S. tuna fisheries.

Fisheries in the United States are among the best managed in the world, thanks to ongoing efforts to  selectively, end overfishing, and rebuild fish stocks. But  could bring dramatic changes in the marine environment that threaten  productivity and sustainability. That’s one reason why researchers set out to broaden the conversation about sustainability in seafood by comparing the carbon emissions of different  fishing practices.

The paper also puts those emissions in context relative to other sources of protein, like tofu, chicken, pork, or beef. In particular, the study examined how the carbon footprint of tuna was affected by how far from shore fishing fleets operated, or what type of fishing gear they used.

“This can be an opportunity to look at fisheries from different angles, all of which may be important,” said Brandi McKuin, the study’s lead author and a postdoctoral researcher in  at UC Santa Cruz.

How Did the Pandemic Affect Ocean Conservation?

April 13, 2021 — As we enter what’s hopefully the home stretch of the COVID-19 pandemic, it’s time to take stock of how it affected every aspect of our world, to consider what happened, what could be done different to avoid those problems in the future, and what’s next.

That might mean confronting some of our earlier conclusions. For example, at the start of the pandemic we were bombarded with often false stories about suddenly quiet cities and waterways experiencing animals reclaiming what was once their habitat. “Nature is healing” stories like this seem to have created an overly rosy picture of the pandemic’s impact on the natural world.

The reality is much more complicated, and I’m not just talking about things like the well-publicized millions of inappropriately discarded plastic bags and protective masks ending up in the ocean. Many other changes to the world’s waters, including some potentially harmful ones, are taking place beneath the surface.

“Protected and conserved areas and the people who depend on them are facing mounting challenges due to the pandemic,” says Rachel Golden Kroner, an environmental governance fellow at Conservation International. Indeed, for the past two decades a sizable chunk of global biodiversity conservation has been funded by ecotourism, a funding source that dries up when international travel slows down, as it did this past year.

Pacific heat wave had lasting impacts on Gulf of Alaska marine species

April 13, 2021 — When a heat wave swept through the northeast Pacific Ocean between 2014 and 2016, it changed the marine makeup of the Gulf of Alaska. The warm water decimated some commercial fish populations.

Some species bounced back right away. But a recent study from NOAA finds others are rebounding more slowly.

NOAA’s study charted the impacts of the heat wave — also known as “the blob” —  on gulf marine species over time, through 2019.

Some of the blob’s impacts on local marine life were immediate. Rob Suryan is a program manager for NOAA in Juneau and the lead author on the study. He said in 2015 and 2016, thousands of common murres were found dead.

“Especially noticeable in the Prince William Sound, near Whittier, actually, a beach was just littered with thousands of carcasses,” he said.

NOAA focused on longer-term trends in this study using data from Gulf Watch Alaska, a group that monitors species recovery in Alaska waters and is funded by the Exxon-Valdez Oil Spill Trustee Council.

Changes in Ocean Conditions and Human Activities Impacted the U.S. Northeast Shelf Marine Ecosystem in 2020

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

Two new reports provide an updated picture of conditions supporting fisheries in the U.S. Northeast Shelf marine ecosystems. One report focuses on Georges Bank and the Gulf of Maine, two ocean regions off New England, and the other report focuses on the Mid-Atlantic Bight. These are the three major regions within the U.S. Northeast Continental Shelf Large Marine Ecosystem.

For the first time, the reports focus directly on how well we have achieved fishery management goals and the risks to achieving those goals posed by ecosystem changes and other human activities. Linkages between environmental conditions and managed species are also highlighted throughout the report. This focus ensures that scientists are providing ecosystem information in a form that the regional fishery management councils can use effectively.

Major findings in this year’s report include:

  • Seafood production trends downward
  • Recreational fishing effort is steady, but fewer anglers are taking for-hire trips
  • Waters continue to warm and marine heat waves continue
  • Less cold, fresh water is entering the Gulf of Maine
  • The Gulf Stream is further north
  • Chesapeake Bay’s warmer winter and cooler spring affected blue crab and striped bass<
  • More fish species are moving to the north and east of their historic distribution, some into deeper water

The reports also cover new and rising factors, including offshore wind energy development and COVID-19 effects on fishery harvests and scientific data collection. There are more than 20 offshore wind development projects proposed for construction over the next decade in the Northeast. They have the potential to impact many parts of the ecosystem. With sufficient data, subsequent reports will further address these factors.

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.”

Alaskan fishing communities ask for seat at climate policy table

April 7, 2021 — Alaskan fishing organizations are urging the administration of U.S. President Joe Biden to listen to coastal communities and fishermen while crafting an ecosystem-based approach to climate change and fisheries policy.

The message from Alaska fishing communities came through recent public comments hearing by the National Oceanic and Atmospheric Administration (NOAA) on the new administration’s executive order on climate change.
