Saving Seafood

JAMES POGUE: Salmon is an indicator species for California’s water crisis. It’s not looking good

June 30, 2021 — In mid-June, California’s State Water Resources Control Board wrote a tragic letter. The board, which has significant powers under California’s Constitution to manage water for the benefit of California’s people and ecosystems, wrote that it would approve a plan for water releases out of Lake Shasta that risk destroying the Sacramento River’s iconic winter-run Chinook salmon population forever.

The winter-run Chinook population has already declined by 99%, down to a few thousand fish that manage to run out of the San Francisco Bay and return to spawn below a dam near Redding. Baby salmon need cold water to hatch from their eggs and grow until they’re ready to migrate to the ocean. But in this drought year, the Federal Bureau of Reclamation has proposed drawing down the levels in Lake Shasta — California’s largest reservoir — to deliver water to irrigators in the Central Valley, allowing the diminished reservoir to heat up over the summer to temperatures that when released into the river “could increase the risk of extinction significantly,” as the board’s own letter put it.

The board, whose members are appointed by the governor, could have modified the plan. Even keeping a small fraction of the water sent for irrigation to be released later could have a dramatic impact on the survival rates of young salmon hatching later in the summer. But holding back water to save fish would have set up a conflict with powerful business interests in the Central Valley.

The board seems to have been more willing to risk the extinction of a salmon run than they were to risk angering landowners and lobbyists. To save even some of the Sacramento River’s salmon population, in a year where pumping water to farms has resulted in dangerously low water flows, California has had to resort to hauling millions of young fish raised in state-run hatcheries via tanker trucks to the Golden Gate. But trucking fish is a desperate measure, one that conceals a larger crisis that is likely to make the fate of fish into one of the key political issues of California’s drought-stricken future.

As Marine Fish Shift With Climate Change, Scientists Work Across Borders to Ensure Sustainability

June 23, 2021 — The following was released by NOAA Fisheries:

The cold waters of the eastern Bering Sea support some of the world’s largest and best-managed commercial fisheries. Sustainable management of these fisheries is founded on scientific information provided by Alaska Fisheries Science Center groundfish surveys. New collaborative research is providing information to ensure accurate local estimates of fish abundance in a changing Bering Sea.

Recent rapid, large-scale movements of fish driven by unprecedented warming in the Bering Sea have created a challenge for survey scientists. As fish populations track their preferred conditions, they are shifting northward and westward, likely beyond historical survey boundaries.

“To maintain sustainable fisheries, managers need to understand how climate is influencing how many fish there are and where they are. As fish populations shift in response to changing ocean conditions, we need to adapt and expand our surveys to provide accurate information that represents the entire population,” said Cecilia O’Leary, NOAA Fisheries biologist, Alaska Fisheries Science Center.

Central Gulf of Alaska Marine Heatwave Watch

June 17, 2021 — The following was released by NOAA Fisheries:

Temperatures are above the long-term average, but remain below marine heatwave conditions. These conditions are wavering near conditions observed in 2017 and 2018 for this season. Recent warming has been sporadic in the region with warmer conditions in the western sector and cooler conditions near Kodiak Island and eastward.

Why monitor marine heatwaves in the Gulf of Alaska?

Climate change is impacting the ecosystem of the Gulf of Alaska and effects are expected to magnify as warming increases over the coming decades. Over the past 6 years, the Gulf of Alaska has been experiencing extended and severe marine heatwaves. From June 2014 to January 2017 the North Pacific, including the Gulf of Alaska, had increased temperatures over a region of approximately 2 million km2 with more than 2.5 °C warmer than the long-term mean (1982–2012). The 2014–2016 marine heatwave changed the ecology of the region with reduced phytoplankton production, a shift in zooplankton production from large lipid-rich (higher fat) copepods to small lipid-poor copepods, and reduced forage fish populations such as capelin (Mallotus villosus) and Pacific sand lance (Ammodytes hexapterus). Species at the top of the marine food chain experienced lower recruitment (reduced juvenile survival) and increased mortality in fishes, birds, and mammals.

We will provide monthly updates on marine heatwave conditions in the Gulf of Alaska via social media @NOAAFisheriesAK and via this webpage. We will share what we are learning about current conditions in the Gulf of Alaska this year.

Is Maldivian tuna being penalized for being sustainable?

June 11, 2021 — In seafood circles, the Maldives is heralded as one of the world’s most-important tuna-fishing nations, an acknowledgement proudly welcomed by Maldivians. But what isn’t so apparent to most non-natives is just how vital tuna is to the island nation. Its 2,000-year history is literally built on catching these universally-prized fish. Moreover, it’s been doing this in pretty much the same way down through the centuries – one-by-one. Essentially, one fisher, using one fishing line, catching one fish at a time.

Its fisheries laws prohibit purse-seining, gillnets, trawl nets, or any other form of commercial fishing that uses a net. At the same time, the country’s exclusive economic zone isn’t leased to other nations and it has a strict policy of not licensing foreign fishing vessels.

JOHN P. HOLDREN: Climate change is rapidly transforming the Arctic: Why everybody should care

June 10, 2021 — The part of Earth’s surface lying north of the Arctic Circle encompasses an area of 7.7 million square miles, of which 70 percent is open or ice-covered ocean. Only eight nations possess territory or territorial waters in this region: the United States (because of Alaska), Canada, Russia, Finland, Norway, Sweden, Iceland and Denmark (because of Greenland). A mere 4 million people inhabit the Arctic. Indigenous people make up about 10 percent of the total, spread across two dozen ethnolinguistic groups (e.g., Inuit, Aleut, Saami).

Beyond its value to the people who live there, however, the Arctic has long been recognized as having considerable importance beyond the region. It is significant militarily, because of the Arctic’s location, linking all of the world’s northern land masses. It’s also significant economically for its oil, gas, strategic metals, and ocean fisheries; and it’s prized around the world, even by people who will never see it in person, for its spectacular landscapes and wildlife.

For the last couple of decades, though, climate change has been transforming practically everything about the Arctic that matters to people both inside and outside of the region. That’s because the Arctic as a whole has been warming two to three times faster than the rest of the world. The accumulating effects of this extreme warming are now manifesting themselves in a multiplicity of ways, some of them creating new economic opportunities, but practically all of them creating major physical, socioeconomic and management challenges for the region. And, of greatest importance for rest of the world, the rapid pace of climate change in the Arctic is influencing the pace and impacts of climate change elsewhere.  It even threatens to undermine the ability of society’s emissions reductions to stop warming worldwide at a level that avoids wholly unmanageable consequences.

$210M federal award to fund UH research focused on how ecosystems are changing

June 10, 2021 — A small trap sits on the coral reef for four months, imprisoning tiny particles for environmental DNA analysis. These findings give researchers a snapshot in time of the microhabitats of our oceans, and in the long-term, a sense of how our ecosystems are changing.

This is just one of the many research projects developed by students at the University of Hawaii at Manoa through the Joint Institute for Marine and Atmospheric Research — a partnership with the National Oceanic and Atmospheric Administration.

Last week, NOAA set plans to continue their 44-year-old partnership, awarding $210 million to the University of Hawaii — more than double the amount of previous funding. The money will go toward the next five years of research for NOAA’s new institute: the Cooperative Institute for Marine and Atmospheric Research.

According to deputy director of NOAA’s Pacific Islands Fisheries Science Center Tia Brown, CIMAR “will help NOAA achieve our mission to better understand the ocean and atmosphere, which depends on all the research that we do … as well as the data and information to make sound decisions for healthy ecosystems, communities and a strong blue economy.”

In fiscal year 2022, CIMAR will continue the work of JIMAR while expanding to eight new research themes: ecological forecasting, ecosystem monitoring, ecosystem-based management, protection and restoration of resources, oceanographic monitoring and forecasting, climate science and impacts, air-sea interactions, and tsunamis and other long-period ocean waves.

Canada launches C$647 mln strategy to stave off Pacific wild salmon collapse

June 9, 2021 — Canada launched a C$647.1 million ($535.10 million) strategy on Tuesday to restore Pacific wild salmon stocks that are on the brink of collapse due to climate change, habitat degradation and harvesting pressures.

The investment, first announced in the federal budget in April, will be the largest ever government contribution to efforts to save the species, which has huge cultural and ecological significance on the west coast.

“Many Pacific wild salmon are on the verge of collapse, and we need to take bold, ambitious action now if we are to reverse the trend and give them a fighting chance at survival,” Fisheries Minister Bernadette Jordan said in a statement.

The government’s Pacific Salmon Strategy Initiative will focus on stronger science and habitat restoration, stabilizing and growing the salmon populations, modernizing fisheries, and deeper coordination between stakeholders including indigenous people and the fisheries industry.

Papers Explore Massive Plankton Blooms with Very Different Ecosystem Impacts

June 8, 2021 — The following was released by the Woods Hole Oceanographic Institution:

“The big mystery about plankton is what controls its distribution and abundance, and what conditions lead to big plankton blooms,” said Dennis McGillicuddy, Senior Scientist and Department Chair in Applied Ocean Physics and Engineering at the Woods Hole Oceanographic Institution (WHOI).

Two new papers explore this question and provide examples of conditions that lead to massive plankton blooms with vastly different potential impacts on the ecosystem, according to McGillicuddy, co-author of both papers. Both papers also point to importance of using advanced technology—including Video Plankton Recorders, autonomous underwater vehicles, and the Ocean Observatories Initiative’s Coastal Pioneer Array—to find and monitor these blooms.

In one paper, Diatom Hotspots Driven by Western Boundary Current Instability, published in Geophysical Research Letters (GRL), scientists found unexpectedly productive subsurface hotspot blooms of diatom phytoplankton.

In the GRL paper, researchers investigated the dynamics controlling primary productivity in a region of the Mid-Atlantic Bight (MAB), one of the world’s most productive marine ecosystems. In 2019, they observed unexpected diatom hotspots in the slope region of the bight’s euphotic zone, the ocean layer that receives enough light for photosynthesis to occur. Phytoplankton are photosynthetic microorganisms that are the foundation of the aquatic food web.
