Saving Seafood

Richard Nelson: Maine’s balking at new greenhouse gas cap threatens seafood industry

A stellar regional program limiting emissions needs support for stronger goals that will save our fisheries.

August 14, 2017 — As a lobsterman for more than 30 years, I have a direct connection to the ocean and its abundance. It’s how I make my living, and I’ve seen it shape my way of life and the people around me. Fishing and seafood are an inextricable part of Maine’s heritage and culture, and it’s thanks to good conservation practices in the lobster fishery that we enjoy the bounty reflected in our record landings of late.

But keeping this way of life requires a continuation of good decision-making now — not only for the health of our ocean, but also for the health of Mainers and our economy. Cutting carbon emissions is an imperative element of that, and we can’t settle for either the status quo or a return to the times and policies that paid little heed to the environment around us.

One program on the state and regional level that has shown great success already, but now faces an imminent decision on its future, is the Regional Greenhouse Gas Initiative. After a 20-month review, a choice must be made on the amount of carbon reduction required — which directly translates into protecting Maine’s people and resources.

Warming Waters, Looming Crisis

It’s no fluke: Fish populations are on the move, chasing cooler marine temperatures. At Rutgers, scientists track their alarming migrations.

August 11, 2017 — In Malin Pinsky’s lab, they keep the unicorn blood in the fridge. It sits alongside dozens of small, white boxes, each containing a snippet of fin or other tissue from the clownfish and summer flounder that, together, may help Pinsky and his colleagues determine the answer to a critical question about the world’s changing oceans. In fact, the unicorn blood—so dubbed by lab manager Michelle Stuart because, Pinsky explains, “it’s expensive and it works magic”—is actually a stew of enzymes used to purify DNA from those fish samples.

The DNA helps Pinsky and his team at Rutgers University in New Brunswick track the movement of fish species over time. What they are finding is likely to have major implications for the commercial and recreational fishing industries in New Jersey and around the world.

For decades, scientists have observed a northward shift in the ranges of many land-based animals in response to a warming climate, among them birds and butterflies. In addition, some mountain-dwelling species, like the pika, a cousin of the rabbit native to the Western United States, have moved to higher altitudes, chasing the cooler temperatures to which they have adapted over millions of years of evolution. Among these observations are scattered reports of the same thing happening in warming ocean waters.

As a marine biologist, Pinsky had read the reports. Concerned about how widespread the changes might be, he and his colleagues ran the first stage of an ongoing research project from 2011 to 2013. The results were startling. “Not only are many species of marine animals, from cod to flounder to lobster, moving to new locations,” says Pinsky, “but it’s happening very rapidly, and it’s affecting a wide range of fisheries, both commercial and recreational.”

Analyzing data collected annually by the National Marine Fisheries Service and its partners, Pinsky’s lab launched the website OceanAdapt, which charts the changing ranges of a wide variety of marine species, regionally and nationally. The site’s graphs depict changes in latitude and sea depth. On a species-by-species basis, those changes are not particularly striking; it’s long been known that fish move around a lot from year to year. But when considering the marine life community as a whole, one observes an indisputable trend northward and downward (to greater depths).

Climate change: 5 signs it’s already begun in New Jersey

August 11, 2017 — By now, most are aware of the dire warnings: Climate change is coming and its effects are going to be especially painful for residents of the Jersey Shore.

While the timing of the truly catastrophic predictions remains fuzzy — Will the barrier islands be lost in 2050? 2100? Later? Sooner? — there are signs that irreversible change has already begun.

From economic and public health challenges to the more obvious outcomes of heat waves and rising seas, climate change has a foothold in New Jersey.

1. Migrating fish

There are about 3,000 commercial fishermen in New Jersey and thousands more who work at processing plants, wholesalers or in shellfishing.

“Fishermen knew about climate change a long time ago,” said Tom Fote, an officer with the Jersey Coast Anglers Association. “We started seeing stocks of fish moving farther north.”

As water temperatures rise, fish move northward, seeking deeper, cooler waters. Higher acidity in the ocean damages crabs, scallops, clams and other shellfish, according to the U.S. Environmental Protection Agency.

On North Carolina’s Outer Banks, A Preview Of What Might Be In Store For Mass. Barrier Beaches

August 9, 2017 — The first truly global disaster resulting from climate change may come from rising sea levels.

The United Nations Intergovernmental Committee on Climate Change has projected sea level rise of 1 to 3 feet by the end of the century, and more recent estimates by NASA and other scientists have projected a rise of up to 8 feet.

In Massachusetts, the rising sea will mean more frequent flooding, more severe storms, and dramatic change.

It’s a problem we will share with every coastal community on every continent. A bit farther down the Atlantic Coast, there’s a place that’s on a faster track to where we too may be headed.

‘These Beaches Are Doomed’

Leonardo Da Vinci wrote that “water is the driving force of all nature.”

Fascinated by great storms and terrible floods, DaVinci would have loved the Outer Banks of North Carolina. Nearly 200 miles of low-lying, shifting sand islands link into a high energy system of waves and storms.

“These beaches are doomed,” says Orrin Pilkey, a professor at Duke University and an octogenarian prophet. “The buildings are doomed too.”

Traveling through a shanty town of triple-decker McMansions on stilts, motels and condos too close to the sea, we stop in the town of Nags Head. Pilkey predicts catastrophe in vacationland.

“The future is one of retreat,” Pilkey says. “It’s the only way to save the beach. It’s the only way to save the buildings.”

Warming Waters Bring New Marine Species to NC, But Chase Away Some Familiar Ones

Bull sharks and lion fish are among the species becoming more common in North Carolina, while black sea bass and other fish are getting harder to find.

August 8, 2017 — A big reason reason North Carolina is seeing so much change in its marine species is because the state has an unusual variety of them, said Sara Mirabilio, a researcher and fisheries extension specialist with North Carolina Sea Grant.

Near Cape Hatteras, the cold Labrador Current comes down from the Arctic, and the warm Gulf Stream flows up from the Gulf of Mexico.

“We are at the northernmost range for southern species and the southernmost range for northern species,” she said. “So climate change at the boundaries will show the most impact.”

In many ways climate change is unfolding as the slowest of slow-motion disasters. But fish can move quickly and for long distances when spurred by relatively small changes in water temperature.

Lately they have moved so quickly that fisheries regulations are lagging, and tensions are rising between commercial fishermen based where the fish used to be, and those where the fish have moved.

On a recent day, Mike Ireland’s 99-foot trawler “Sharon Nicole” was docked behind a seafood wholesaler in the Hobucken community east of New Bern, just off the Pamlico Sound.

Shrimp season was under way, but he and his crew were repairing one of the massive, powered winches that haul in their nets. It was an especially crucial one, because it reels in the small net they drag to locate fish.

“This is probably the most important tool on the boat,” Ireland said. “With this little sample net you can really pinpoint where they’re at.”

Senate Subcommittee Holds First Hearing to Guide Magnuson-Stevens Reauthorization

August 2, 2017 — The Magnuson-Stevens Act, the primary law regulating fisheries in federal waters, is in need of reauthorization, and Senate Commerce’s Subcommittee on Oceans, Atmosphere, Fisheries and Coast Guard on Tuesday held the first in a series of hearings to guide that process. And, unsurprisingly, the issue of climate change made waves.

Chris Oliver, assistant administrator of NOAA’s National Marine Fisheries Service, and John Quinn, chairman of the New England Fishery Management Council, pushed for a variety of changes, ranging from management of mixed stocks to more flexibility in how the Council Coordination Committee can monitor and collect data. But it was Sen. Richard Blumenthal who made the strongest case for change by criticizing the current system for failing New England’s fishing fleet and leaving the region’s fishermen “angry and frustrated beyond words.”

Because of climate change, Blumenthal said, fish that New England fishermen have traditionally sought were pushed north and fish from southern waters moved into New England. But catch limits for certain fish haven’t been adjusted to meet the reality facing New England fishermen, forcing them to return quota-exceeding fish to the ocean. Billions of dollars in profits are being lost, Blumenthal said, while fishermen from southern states come to New England waters to catch their migrating fish. “There is something profoundly unfair and intolerable about the situation,” he added. “In my view, it violates the present law.”

Quinn responded by pointing out that parts of the New England fishing industry are booming but agreed that groundfish fishermen are struggling. While the CCC’s process is to collect as much data as needed to produce accurate stock assessments, Quinn said they didn’t have “a simple solution for rising water temperatures or the ocean acidification,” which are the roots of the shifting fish populations.

Fishing Partnership Support Services: Pass a price on carbon to protect fisheries and livelihoods

July 31, 2017 — A few years ago, scientists, fishermen and fishing managers concluded that cod stocks were rebuilding off the coast of Massachusetts. This understanding led ground fishermen (those who catch cod and other groundfish) spanning coastal New England to invest their life savings into their fishing businesses.

Soon after, industry experts changed their tune, reporting that drastic changes were underway. With livelihoods and families on the line, cod stocks began collapsing, leaving thousands devastated both financially and mentally. Today, an astounding 87 percent of Massachusetts ground fishermen suffer from mild to severe PTSD after experiencing the financial consequences of the crash, according to a Northeastern University study.

The situation only worsens as fishermen resort to unsafe practices — going farther out to sea in subpar boats, downsizing crews, and working longer hours on insufficient sleep. It is no surprise that New England ground fisherman are 200 times more likely to die on the job than the average worker, and that fishermen have the highest suicide rates among U.S. workers.

With ocean temperatures in the Northeast increasing more rapidly than global averages, sea animal populations are already noticeably shifting. Populations of cod, lobster, sea bass, and many others are decreasing in size or migrating farther north. And in turn, food chains are altered and fishermen struggle to pay the bills.

From cod to fishermen to families, climate change has the power and potential to cause true devastation, and the time to act is now. In Massachusetts, we have the opportunity to confront this issue head-on and cut greenhouse gas emissions through carbon pricing legislation H.1726 and S.1821.

Australia Seeks to Extend Commercial Fishing in Protected Waters

July 21, 2017 — Australia plans to allow fishing across 80 percent of its protected maritime sanctuaries, the government said on Friday in a proposal that would vastly extend commercial activity in the world’s largest marine-reserves network.

If the plan, backed by the government of Prime Minister Malcolm Turnbull, is approved by Parliament, it would be the first time a nation has scaled back its regulations in protected maritime areas. The move could potentially set a precedent for other countries, including the United States, which are considering similar reversals.

More than one-third of Australia’s waters — home to endangered species of sharks, turtles and whales — are protected by law.

Under the government’s proposal, “the boundaries of Australian Marine Parks will not change,” Josh Frydenberg, the environment minister, said in a statement. Instead, he said, the country would increase “the total area of the reserves open to fishing from 64 percent to 80 percent.”

Much of the increased fishing would take place in the Coral Sea Reserve, one of the country’s most stringently protected areas, where large-scale operations would be allowed for first time in at least five years. Most fishing is now prohibited in the park, off the continent’s northeast coast, by a so-called no-take zone.

Oil impairs ability of coral reef fish to find homes and evade predators

July 18, 2017 — Just as one too many cocktails can lead a person to make bad choices, a few drops of oil can cause coral reef fish to make poor decisions, according to a paper published today in Nature Ecology & Evolution. A team of fisheries biologists led by Jacob Johansen and Andrew Esbaugh of The University of Texas Marine Science Institute have discovered that oil impacts the higher-order thinking of coral reef fish in a way that could prove dangerous for them—and for the coral reefs where they make their home.

Examining six different species of , Johansen and the team found that exposure to oil consistently affected behavior in ways that put the  at risk.

During several weeks when coral  fish go through their juvenile stages of development, they are especially vulnerable. Even in healthy populations of reef fish, typically less than 10 percent of embryos and larvae reach adulthood. Those who survive must learn to identify friend from foe and adopt protective behaviors, such as traveling in groups, minimizing movement in open waters and swimming away quickly from danger.

In experiments, the scientists found that juvenile fish exposed to oil struggled on all these counts.

“In several different experiments, the fish exposed to oil exhibited very risky behavior, even in the presence of a predator,” said Esbaugh, an assistant professor of .

The scientists also found that oil exposure negatively affected the fishes’ growth, survival and settlement behaviors (their ability to find a suitable habitat).

Oil concentrations are found in oceans worldwide, but until now little has been known about the impact of oil exposure on coral reef fish. Earlier research that explored how oil affects the physiology of fishes has demonstrated developmental heart deformities and associated cardiac functions, but this is the first study to demonstrate that oil exposure affects behavior in a way that increases predation and reduces settlement success.

NOAA to Deploy Saildrones for Climate Study

July 18, 2017 — During the next four months, NOAA scientists will deploy Saildrone unmanned ocean vehicles to hard-to-reach locales such as the Arctic and the tropical Pacific with the goal of better understanding of how ocean changes affect weather, climate, fisheries and marine mammals.

The Saildrone is wind and solar-powered research vehicle resembling a sailboat, capable of performing tasks at sea such as met ocean data collection, environmental monitoring and fish stock analysis, autonomously or under remote control. For NOAA, the vehicles will soon travel thousands of miles across the ocean, reaching some areas never before surveyed with such specialized technology.

In mid-July, scientists will send off the first unmanned, wind and solar-powered vehicles from Dutch Harbor, Alaska, with two sailing north through the Bering Strait into the Arctic Ocean and another transiting the Bering Sea. Traversing Alaska’s inhospitable waters, the remote-controlled vehicles will track melting ice, measure carbon dioxide in the ocean and count fish, seals and whales.

For the first time, the vehicles will journey through the Bering Strait into the Arctic with a newly adapted system to measure CO2 concentrations.

We want to understand how changes in the Arctic may affect large-scale climate and weather systems as well as ecosystems that support valuable fish stocks,” said Jessica Cross, an oceanographer at NOAA Research’s Pacific Marine Environmental Laboratory, who is using the unmanned system to study how the Arctic Ocean is absorbing carbon dioxide.
