Biologists suspect New York bay scallops are latest victim of warmer waters

November 20, 2019 — The famed bay scallops of eastern Long Island came back after their near-death experience of brown tides only after years of a dedicated restoration effort. Now biologists are worried the fishery may be at risk with increasing water temperatures.

New York baymen are seeing the worst Peconic Bays scallop season in years, after summer 2019 water temperatures that reached a sustained July peak of 84 degrees in some places.

The scallops were devastated by severe brown tides for more than a decade starting in 1984 and were nurtured back with many years of work by scientists, baymen, aquaculture experts and volunteers. The shellfish face other threats like being eaten by cownose rays and other predators. But biologists think this situation is different.

“I do believe this one in dues to high water temperatures and low dissolved oxygen that may have coincided with spawning,” Long Island University professor Steve Tettlebach who works with the Cornell Cooperative Extension told National Fisherman. “So, the combination of these stressors is the most plausible explanation for the die-off of adults.”

The damage became evident during the Cornell fall scallop survey when workers found thousands of empty shells, and baymen came home largely empty-handed from the fall season.

ALASKA: Northern Bering Sea trawl survey shows fisheries in flux

November 19, 2019 — Norton Sound red king crab are moving, Arctic cod numbers have dropped significantly and Pacific cod are continuing to increase as the Northern Bering Sea ecosystem undergoes drastic change. That’s all according to preliminary results from a National Oceanic and Atmospheric Administration trawl survey this summer in the Northern Bering Sea (NBS).

Before Lyle Britt even began leading the NOAA Fisheries’ study of the NBS in September, he anticipated seeing more warm water fish in a region that stretches from Nunivak Island north to the Bering Strait.

“We can tell that the ecosystem is very much in flux up here,” Britt said. “We’re seeing expansion of ranges of some fish and invertebrates, and we’re seeing the retraction of others. Now how permanent or ephemeral those are, I think is still in question.”

As an example of a species that’s expanding its range based on what was discovered in the 2010 baseline survey of the Northern Bering Sea, Britt points to Pacific cod.

“Between 2010 and 2017 there was about a 900% increase in the amount of Pacific cod we saw in the Northern Bering Sea region, based on that biomass or total weight estimate,” he said. “That number sounds really dramatic in part because there were so few in 2010 and now there are some. That number increased between 2017 and 2019 by about 30%, so it’s continued to go up.”

UMaine Launches Initiative To Help Mainers Understand How State Is Affected By Arctic Climate

November 18, 2019 — The University of Maine is launching an initiative designed to help Mainers better understand how the state is affected by Arctic climate.

Called “UMaine Arctic,” the project explores how the changing climate will impact the state’s fisheries, native populations and coastal communities.

“The Arctic has a huge impact on life in Maine,” says Christopher Gerbi with UMaine’s College of Natural Sciences, Forestry and Agriculture. He says the Gulf of Maine is fed by waters from the arctic regions of Canada and Greenland.

“As the water changes temperature, that changes the temperature in the Gulf of Maine, which has a huge impact on all our fisheries, the lobster industry,” he says.

And on all of the industries that rely on those industries, such as marine suppliers, restaurants and coffee shops in coastal communities, says Gerbi.

Top climate hawk bashes first big offshore wind project

November 15, 2019 — For the past seven years, Sen. Sheldon Whitehouse has given a weekly address about the dangers of climate change. Increasingly, some greens wonder if he is full of hot air.

The Rhode Island Democrat, one of the Senate’s top climate hawks, has emerged as a leading critic of Vineyard Wind, an 84-turbine offshore wind project proposed in federal waters 15 miles south of Martha’s Vineyard. Whitehouse has questioned the federal government’s review of the project, the first large-scale development of its kind in the United States, and criticized Vineyard Wind for failing to adequately consult fishermen.

His barbs have raised eyebrows in climate circles and in Massachusetts, where Vineyard Wind has the enthusiastic backing of the state’s political establishment, and comes as the Trump administration weighs the future of the project.

In August, Interior Secretary David Bernhardt called for an additional round of environmental review of the project (Climatewire, Aug. 12). A division of Interior, the Bureau of Ocean Energy Management, is currently conducting a cumulative impact study of other offshore wind projects proposed for the area.

In an interview, Whitehouse said he was simply pushing for improvements to BOEM’s permitting process to better accommodate the concerns of fishermen and other ocean users.

He argued that Vineyard Wind had already settled on the design of its project with investors before taking input from fishermen. And he cited the Block Island wind farm, a five-turbine project built by Rhode Island-based Deepwater Wind, as an example of how wind developers should approach fishermen’s concerns.

Keating said he appreciates the difficulty Whitehouse faces in balancing the concerns of fishermen next to the economic potential of offshore wind. He represents New Bedford, Mass., America’s largest commercial fishing port, and has heard similar concerns about offshore wind from some constituents. But he added: “I really feel an urgency and I feel an imperative that we have to go forward on this. This is gonna be great for our economy.”

Food security starts at sea

November 13, 2019 — By 2050, global food production must increase by 70 percent to keep up with population growth. The pressure to grow, harvest and create more protein from America’s resources will be immense. Yet, America owns vast wealth in and near our coastal communities that permeates across state lines. This wealth must be protected for businesses, community survival and our nation’s food security.

Every summer, the wealth of our fisheries is seen coast to coast. Wild salmon return to pristine Alaskan waters, striped bass reappear near New England’s shores, and red snapper congregate in the Gulf of Mexico. As leaders of the Seafood Harvesters of America and lifelong fishermen, we shared stories like these — the story of the American fisherman — during the summer’s Capitol Hill Ocean Week.

Like any robust American resource, fisheries connect businesses, communities and families across the nation around hard work and resiliency. Renewable and sustainably managed, it has the capacity to help feed us in perpetuity.
But does it?

In 2017, U.S. commercial fishermen landed an astounding 9.9 billion pounds of seafood. Americans love the idea of eating American seafood. We celebrate it on menus and grocery store banners, devour dramatic fishing documentaries, and honor its heritage in our coastal towns. As a nation we’ve prioritized sustainability through laws like the Magnuson Stevens Act, which is why 91 percent of America’s fishery stocks are not overfished today — and that number is only improving.

Save Our Seas 2.0 tackles global marine debris crisis

November 12, 2019 — We may have plenty of political differences, but we come from coastal states. That means we have a front-row seat to the peril of plastic waste and marine debris flowing into our oceans at the rate of around 8 million metric tons per year. We understand what it will mean for our fishing and tourism industries when the weight of plastic in our oceans equals the weight of fish in the sea — something projected to happen by mid-century. We don’t have a moment to lose in confronting this problem.

That’s why we built a coalition in Congress and gathered input from environmental and industry stakeholders alike. Despite a divided Washington, that work resulted in a bill that won broad, bipartisan support. When the Save Our Seas Act became law last October, it was a moment of bipartisan progress on a vital issue — one to be celebrated.

Before the president’s ink on Save Our Seas was dry, our bipartisan trio of senators began developing the Save Our Seas 2.0 Act. We sought to harness the momentum behind the first bill to up the ante on combatting the global marine debris crisis. Marine debris requires multifaceted, multisector solutions with a global reach, and the United States ought to be driving these solutions.

The climate chain reaction that threatens the heart of the Pacific

November 13, 2019 — Lined up along the side of their boat, the fishermen hauled a huge, heavy net up from swelling waves. At first, a few small jellyfish emerged, then a piece of plastic. Then net, and more net. Finally, all the way at the bottom: a small thrashing mass of silvery salmon.

It was just after dawn at the height of the autumn fishing season, but something was wrong.

“When are the fish coming?” boat captain Teruhiko Miura asked himself.

The salmon catch is collapsing off Japan’s northern coast, plummeting by about 70 percent in the past 15 years. The disappearance of the fish coincides with another striking development: the loss of a unique blanket of sea ice that dips far below the Arctic to reach this shore.

The twin impacts — less ice, fewer salmon — are the products of rapid warming in the Sea of Okhotsk, wedged between Siberia and Japan. The area has warmed in some places by as much as 3 degrees Celsius since preindustrial times, making it one of the fastest-warming spots in the world, according to a Washington Post analysis of data from the nonprofit organization Berkeley Earth.

Marine Heatwave in the Pacific Shrinks from “Blob” in Size, Retreats Farther Offshore

November 11, 2019 — The following was released by NOAA Fisheries:

The vast marine heatwave that spread warm temperatures across the northeast Pacific Ocean late in the summer and fall of 2019 has declined in size and pulled back from the West Coast, possibly reducing its immediate impacts on coastal ecosystems.

It has declined to about half the size and intensity it displayed in August. However scientists caution that the heatwave designated MHW NEP19a remains two to three times the size of Alaska and still retains enormous amounts of heat in the upper layers of ocean. It remains one of the top four or five largest heatwaves on record in the North Pacific in the last 40 years.

“What we are seeing now is a smaller heatwave that is farther offshore, but there is still a very large span of the Pacific Ocean that is much warmer than usual,” said Andrew Leising, a research scientist at NOAA Fisheries’ Southwest Fisheries Science Center (SWFSC) in La Jolla, California. Leising has developed criteria to detect and gauge the size and magnitude of marine heatwaves. “The question is, where does it go from here? That’s what we’re watching now.”

The edge of the heatwave is now about 1,500 kilometers (about 930 miles) from the West Coast, but still envelops much of the Gulf of Alaska. It no longer so closely resembles the enormous earlier marine heatwave known as “the Blob” that affected much of the West Coast through 2014 and 2015, causing reverberations through the food web.

Low salmon returns to many West Coast rivers in the last few years have been linked to the Blob, which reduced the availability of food when the salmon first entered the ocean as juveniles.

Climate change and overfishing are boosting toxic mercury levels in fish

November 11, 2019 — We live in an era—the Anthropocene—where humans and societies are reshaping and changing ecosystems. Pollution, human-made climate change and overfishing have all altered marine life and ocean food webs.

Increasing  temperatures are amplifying the accumulation of neurotoxic contaminants such as organic mercury (methylmercury) in some marine life. This especially affects top predators including marine mammals such as fish-eating killer whales that strongly rely on large fish as seafood for energy.

Now the combination of  pollution, climate change and overfishing are conspiring together to further contaminate marine life and food webs. This has obvious implications for ecosystems and the ocean, but also for public health. The risk of consuming mercury-contaminated fish and seafood is growing with climate change.

Rep. Joe Cunningham: A healthy ocean in 2050? We need to act now.

November 8, 2019 — The ocean is the lifeblood of our planet. It covers three quarters of the globe, produces more than half our oxygen, supports a wide range of marine fisheries that feed the planet, and absorbs 30 percent of the carbon dioxide we emit and 90 percent of the heat caused by those emissions.

In short, the ocean plays a critical role in our lives and livelihoods. And it’s just as critical that we do everything we can to protect it.

By 2050, the global population is expected to reach 9.7 billion people. While the projections regarding the impact that this population and their actions and emissions will have on the ocean may vary, none of them are good. Without definitive action now, scientists predict that by 2050:

• World fish stocks will be driven to collapse;
• Average sea levels will rise by 30-34 centimeters, increasing coastal erosion and exacerbating storms, flooding cities and coastal communities like Charleston;
• The ocean is expected to contain more plastics than fish (by weight); and
• The world’s coral reefs will be wiped out, increasing threats to coastal communities from storm surges and a loss of fish stocks that rely on corals for survival.
