How a new simulator helps scientists study whale entanglements

November 23, 2018 — More than 80 percent of North Atlantic right whales become entangled in fishing lines at least once in their lives, making it a leading cause of death for the critically endangered whale species. Now, with the help of new entanglement simulation technology, scientists at the New England Aquarium are working to change that.

Tim Werner, a senior scientist at the aquarium’s Anderson Cabot Center for Ocean Life, is one of several aquarium researchers who collaborated with scientists from Duke University to develop a graphic model that gives them an opportunity to study entanglements and potential solutions in a practical and humane setting, aquarium officials said in a press release.

“This gives us a tool we can use right away to say, ‘If you have an idea, let’s evaluate it,’ and we can evaluate it over the course of several days rather than over the course of several years,” Werner said in a telephone interview.

The goal for developing the model was to reverse-engineer entanglements in order to figure out ways to modify fishing gear so that it poses less of a risk to helpless marine animals going forward.

“If you can re-create the way the rope wraps around the animal in the model, you can figure out how to change the gear to reduce the risk of entanglement,” Werner said, according to the release.

NOAA Funds Projects to Reduce Bycatch With Engineering

September 4, 2018 — A group of organizations is getting more than $2 million in grants to use engineering to try to reduce bycatch in fisheries.

Bycatch is the term for when fish and other animals are accidentally caught with gear that was seeking a different species. Bycatch poses problems for rare species of dolphins, turtles, sharks and other animals.

The National Oceanic and Atmospheric Administration is awarding more than $2.3 million to 14 projects as part of its 2018 Bycatch Reduction Engineering Program.

One of the recipients is Duke University, which will test the applicability of sensory-based bycatch reduction technology. Duke’s project seeks to reduce sea turtle bycatch in North Carolina.

Models may help reduce bycatch from longline fishing

August 10, 2018 — Hundreds of thousands of sharks, sea birds and other marine species are accidentally killed each year after they become snagged or entangled in longline fishing gear.

New models developed by a Duke University-led team may help reduce this threat by giving regulatory agencies a powerful new tool to predict the month-by-month movements of longline fishing fleets on the high seas. The predictions should help determine where and when the boats will enter waters where by-catch risks are greatest.

“By comparing our models with data showing where by-catch species are likely to be each month, ship captains, national agencies and regional fisheries management organizations can pinpoint potential hotspots they may want to temporarily avoid or place off-limits,” said Guillermo Ortuño Crespo, a doctoral candidate in the Marine Geospatial Ecology Lab at Duke’s Nicholas School of the Environment.

“This represents a movement away from a reactive approach to fisheries management — where we only know about problems as or after they occur — to a more proactive approach that helps us stay one step ahead of the game,” he said.

Ortuño Crespo and his colleagues describe their new models in a peer-reviewed paper August 8 in Science Advances.

To devise the models, they collaborated with Global Fishing Watch to collect geospatial information from individual boats’ automatic identification system (AIS) signals. AIS data shows the movements and distribution of longline fishing fleets operating in the high seas in 2015 and 2016.

Then they statistically correlated each ship’s fishing efforts to 14 environmental variables — such as sea surface temperatures or distance to the nearest seamount — that influence a region’s seasonal suitability as a habitat for species targeted by longliners. This allowed them to create highly accurate models that predict where the fishing fleets will be each month of the year.

The new models track data for fleets from Japan, South Korea, Taiwan, China and Spain, which accounts for most of the longline fishing currently taking place in the open ocean beyond national jurisdictions. Future models could include fleets from other nations and offer expanded functionality that will allow regulatory agencies to view the data within a global context or break it down by individual nation, region or fleet.

Why should you care about fisheries? They can help feed the world.

May 16, 2018 — Food security is a hot button topic for today’s world leaders, and rightly so as the population swells to 10 billion people by the middle of the century. Feeding that many people is a huge challenge – creating an urgent call to action for resources to be managed more sustainably and equitably – and wild seafood plays a big role.

Typically, these discussions focus on land-based agriculture, including the production of grains, seeds, crops and livestock that, while subject to droughts, diseases and shortages, are the main source of world food consumption as measured by total calories. However, food sources from our oceans, lakes and rivers also play a large part in feeding the world, and deserve their place in the discussion.   

That’s why we’re excited to share a new report from Duke University and EDF* examining how wild capture fisheries fit into this complex discussion and summarizing what we know about the potential role of fish and other aquatic resources, like shellfish and crustaceans, to help feed an increasingly hungry world. After all, three billion people rely on seafood as a primary source of protein, and this number will only continue to grow.

NOAA Names Michael Pentony to Lead Greater Atlantic Region

January 11, 2018 — The following was released by NOAA Fisheries:

Today, NOAA Fisheries announced that Mr. Michael Pentony is the new Regional Administrator for NOAA Fisheries Greater Atlantic Regional Fisheries Office in Gloucester, Massachusetts. He will assume his new duties on January 22, 2018. Mr. Pentony has been with the agency since 2002, serving in a series of positions including as the Assistant Regional Administrator for the Sustainable Fisheries Division since 2014. He succeeds retiring Regional Administrator John Bullard who had been in the position since 2012.

“I am extremely pleased to announce this appointment,” said NOAA Fisheries’ director Chris Oliver. “Michael’s deep experience in every aspect of sustainable fisheries management, both commercial and recreational, positions him perfectly for this job. He is going to hit the ground running.”

In his new role, Mr. Pentony will head the agency’s regional office, which has responsibility for managing approximately 100,000 square miles of the Northwest Atlantic, the large marine ecosystem from Maine to Cape Hatteras and the Great Lakes. To do that, the office works closely with two fishery management councils, the states, the fishing industry, and other stakeholders to manage federal commercial and recreational fisheries, marine mammals, habitat, and much more. As Administrator, he will also oversee critical aspects of international fisheries conservation and management in the region.

Mr. Pentony has extensive experience leading the development and implementation of the fishery management plans and regulations established by the Mid-Atlantic and New England Fishery Management Councils and the Atlantic States Marine Fisheries Commission. In his role as the region’s lead for sustainable fisheries management, he oversaw all aspects of 14 management plans targeting 42 species valued at nearly $1.6 billion annually. Prior to taking the Assistant Regional Administrator position in 2014, Mr. Pentony served for 12 years as a team supervisor in the sustainable fisheries division.

“Under Michael’s leadership, the region’s sustainable fisheries team worked hard to meet the needs of fishermen and fishing communities from Maine to North Carolina. In doing so, they have implemented successful, innovative approaches to protecting and restoring stocks, habitat, and marine mammals. They also paved the way for an expansion of the aquaculture industry in the region by working hard to break through barriers to that industry,” said Oliver.

Before joining NOAA Fisheries in 2002, Mr. Pentony worked for five years as a policy analyst for the New England Fishery Management Council, primarily on issues related to habitat, marine protected areas, and the deep-sea red crab fishery.

He has a Bachelor of Science in Engineering from Duke University in North Carolina, and a Master’s of Environmental Management from the Nicholas School of the Environment at Duke University. Between college and graduate school, Mr. Pentony served for six years as an officer in the United States Air Force as an engineering project manager on a variety of military satellite and launch vehicle programs.

Michael grew up in the town of Point Pleasant, New Jersey, where he spent his summers fishing for bluefish and fluke at the Manasquan Inlet. He currently lives in New Hampshire with his family including his wife and daughter. In his free time he enjoys traveling with his family, cheering on his daughter at swim meets, cycling the back roads of New Hampshire, and trying to learn to play the bass guitar.

Trump administration nears decision that sets stage for offshore drilling in the Atlantic

September 11, 2017 — Environmental groups are bracing for the Trump administration to approve controversial testing along the Eastern seaboard that would mark a significant step toward offshore drilling in waters off the coast of Florida all the way north to the Delaware Bay.

Five geophysical survey companies are seeking federal permission to shoot pressurized air blasts into the ocean every 10 to 12 seconds around the clock for weeks and months at a time, seeking fossil fuel deposits beneath the Atlantic Ocean floor.

The testing, which would cover 330,000 square miles of ocean, faces fierce opposition from environmental groups and local officials due to the possible economic and environmental effects.

Because the underwater blasts are louder than a Saturn V rocket launch and can be heard by monitoring devices more than 2,500 miles away, scientists fear long-term exposure to the noise could cause hearing loss and impair breeding, feeding, foraging and communication activity among dolphins, endangered whales, other marine mammals and sea turtles.

Some worry the blasts could cause mother whales and their calves to become separated. Commercial and recreational fisheries could also be affected if fish change their breeding and spawning habits to avoid the noise. Others fear disoriented marine life could collide with the vessels that tug the air guns or become entangled in their lines. Oceana, an international conservation group, estimates that 138,000 marine mammals could be injured in the testing process.

Seventy-five marine scientists asked the Obama administration in 2015 to reject seismic air gun testing in the Atlantic because of these threats. Twenty-eight marine biologists did the same in 2016 over concerns that testing would harm the estimated 500 endangered North Atlantic right whales.

“That’s the species we are most concerned about,” said Doug Nowacek, associate professor of conservation technology at the Duke University Marine Laboratory in Beaufort, North Carolina. “They are in decline. They live coastally along the U.S. They were hunted (by whalers) and they were slowly recovering. And now they’re starting to decline again.”

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.”

100-shark milestone surprises even researchers

October 11th, 2016 — With a quick jab, Greg Skomal reached a milestone last week. The detachable stainless steel tip on his harpoon penetrated the skin of a 14-foot male great white shark hunting seals just 20 feet off Nauset Beach. The dart lodged between the tendons at the base of the shark’s dorsal fin, tethered to a pencil-size acoustic tag that will broadcast a signal identifying the shark for the next decade.

Skomal had tagged his 100th great white, dating back to 2009 when the massive predators began showing up in appreciable numbers off Chatham. He named the shark Casey after shark tagging pioneer Jack Casey, who founded the National Marine Fisheries Service Cooperative Shark Tagging Program in 1962 and developed many of the techniques still in use today.

As the number of sharks coming to the Cape seems to grow every year, so has Skomal’s appreciation of the unique situation he finds himself in: a shark researcher caught in a real-life “Sharknado.”

“If you told me 10 years ago we’d hit a hundred, I’d say, ‘You’re crazy,’” he said.

The number of sharks ranging along the Cape’s shoreline, many passing near surfers and swimmers, is sobering. Skomal, a senior fisheries biologist with the state Division of Marine Fisheries, is finishing the third year of a five-year population study and has identified more than 200 individual sharks through tagging and underwater videos that find unique scars and coloration on each animal.

“Frankly, I was surprised nobody got bit this summer,” said Chris Lowe, a professor at California State University, Long Beach, noting that seals and sharks have modified their behavior to the point where the sharks must hunt in increasingly shallow waters, including the popular beaches where millions swim every summer.

A soon-to-be published study of seven adult gray seals, captured and tagged on the Cape three years ago by a team led by Duke University professor David Johnston, showed them leaving the shore to feed at all times of day and night, and taking multiday trips, when sharks are not around in the winter. But the summer is a different story. Johnston said the study found seals have adapted their behavior to better avoid white sharks. Since great whites rely heavily on their eyesight to hunt, tagged seals were leaving at twilight and taking only single day trips in summer, he said.

FDA nominee sails through Senate committee, but could a fish stand in his way?

January 12, 2016 — A Senate health committee on Tuesday easily advanced the nomination of former Duke University researcher and cardiologist Robert Califf as the next commissioner of the Food and Drug Administration. But Califf, while widely expected to win confirmation from the full Senate, faces at least one surprise hurdle on the way to his new job: genetically engineered salmon.

Sen. Lisa Murkowski (R-Alaska) told her colleagues on the committee that met Tuesday to vote on Califf’s nomination that she is willing to stall it until he and FDA agree to mandatory labeling requirements for the AquaAdvantage salmon.

The salmon, produced by Massachusetts-based AquaBounty and approved by the agency in November, is an Atlantic salmon that contains a growth hormone from a Chinook salmon and has been given a gene from the ocean pout, an eel-like fish. The result is a fish engineered to grow twice as fast as its natural counterpart. The first genetically altered animal approved for human consumption, it has been the subject of long-running fights involving food-safety activists, environmental groups and the salmon fishing industry.
