Great whites attracted by plentiful seal populations in Maine waters

July 29, 2020 — Monday’s fatal shark attack off Harpswell is the result of rebounding great white shark and seal populations along the Maine coast, experts say.

The attack on Julie Dimperio Holowach, 63, was the first fatal shark attack in the state’s history. A diver was attacked off Eastport in 2010, according to the Florida Museum’s International Shark Attack File, but he was not injured and fended off a porbeagle shark with his video camera.

Seal populations have grown since a 1972 law barred killing of marine mammals and white shark numbers have been rebounding for two decades as a result of a rule that said fishermen could no longer kill the fearsome predators, a shark expert based in Massachusetts said.

Gregory Skomal of the Massachusetts Division of Marine Fisheries dismissed speculation that warming water temperatures in the Gulf of Maine might be enticing more great whites to the state’s coastline.

He said the sharks always have been frequent visitors to Maine waters, but that growing seal populations might be drawing them closer to the shore. Seals are a favorite food of the great white, he said.

Scientist: Increase In Seal Population Likely Attracting More Sharks To Maine Waters

July 29, 2020 — The Maine Department of Marine Resources has identified Julie Dimperio Holowach, of New York City, as the victim of a shark attack near Bailey Island yesterday. She was pronounced dead after being helped to the shore following the attack.

It may be the first recorded encounter of its kind in Maine and has sparked beach closures in parts of the state.

Dr. Nick Whitney, senior scientist and chair of the Fisheries Science and Emerging Technologies Program with the New England Aquarium in Boston, spoke with Maine Public’s Nora Flaherty about why there might be more sharks in Maine now than there have been in the past.

Dr. Whitney: I think it’s generally accepted that the increase in number of seals is leading to more white sharks coming closer to shore during some months. Other than that, I’m not sure if there’s been any major changes in migration patterns. Sharks have probably been using these waters for decades or longer.

Reminder to Give Seals Space

April 1, 2020 — The following was released by NOAA Fisheries:

As more people are taking to the outdoors and we approach harbor seal pupping season, we are asking the public to help us by social distancing with animals too! Respect the social distance that is required by these sensitive animals. Help our stranding responders stay safe by not endangering, touching, or closely approaching  potentially healthy animals.

Hawaiian Monk Seal Population Saw Signs of Recovery in 2019

March 19, 2020 — The following was released by NOAA Fisheries:

The Hawaiian monk seal population has shown some signs of recovery over recent years. The size of the monk seal population in 2019 was about the same as in 2018, with slightly more than 1,400 seals. Most of the population (about 1,100 seals) reside in the remote Northwestern Hawaiian Islands. Just about 300 seals call the main Hawaiian Islands home. While the population size hasn’t really changed since last year, the population trend remains positive in recent years. It has been growing at an average annual rate of 2 percent since 2013.  The potential for our continued conservation efforts to make such a positive impact is part of what makes Hawaiian monk seals one of NOAA’s Species in the Spotlight.

NOAA’s Hawaiian Monk Seal Research Program closely tracks these year-to-year population trends, thanks to a robust, long-term dataset. During the 2019 field season, dedicated field biologists lived and worked on remote islands in the Northwestern Hawaiian Islands for 3 to 5 months (depending on the site). In the main Hawaiian Islands, we rely on volunteers, members of the public, and agency partners who contribute to citizen-based seal monitoring.

What lives, what dies? The role of science in the decision to cull seals to save cod

March 16, 2020 — Atlantic cod on the Grand Banks of Newfoundland supported one of the world’s greatest fisheries for over three centuries. Yet this seemingly inexhaustible resource is in bad shape. Some stocks are now endangered and their survival could depend on removing a key predator, the grey seal.

This raises some difficult questions: How do we determine the value of one species over another, and what is the role of science in this conundrum?

My colleagues and I in the Fisheries Economics Research Unit at the University of British Columbia are fascinated by these questions. As an interdisciplinary group of economists, ecologists and social scientists, we commonly attribute values to animals in different ways. But determining whether to kill one animal to preserve another is less straightforward.

The collapse of the Grand Banks fisheries is considered one of the most significant failures in the history of natural resource management — akin to the ongoing degradation of the Amazon — and casts a long shadow over Canadian fisheries management.

Rare Visitors: Harp Seals in New England

March 12, 2020 — The following was released by NOAA Fisheries:

While we’re used to seeing harbor and gray seals in New England, we occasionally get seal visitors from the Arctic. In late winter, it’s not unusual—though it is rare—to see harp seals on our beaches.

Sometimes well-meaning people come across these seals and, while wanting to help them, do exactly the things that cause these animals stress.

Find out more about these seals, and what you should do — and not do — if you come across one on the beach.

NOAA concerned with parasite that kills monk seals that’s spread by cat feces

February 21, 2020 — Toxoplasmosis, a parasite found in cat-feces is threatening the survival of Hawaiian Monk Seals. It’s deadly and it works quickly. According to scientists with the National Oceanic Atmospheric Administration, it can kill within 48 hours. It’s listed as one of the top three threats against the endangered species.

Dating back to the 90’s, NOAA reports at least 12 seals have died because of Toxoplasmosis. There’s no exact count because not every corpse has been recovered.

“That doesn’t sound like a very high number but when there’s only 250 to 300 animals in the population that are being impacted by this, it’s significant,” Charles Littnan, Protected Species Division Director, NOAA Pacific Islands Fisheries Science Center, said.

It spreads when cat feces are washed into the ocean, contaminating the water. One seal was killed last month. Another, Pohaku, is recovering after a bystander spotted her logging or floating in the water.

ALASKA: Bristol Bay seal suit: Endangered listing could disrupt Pebble Mine permit

February 13, 2020 — On Wednesday, Feb. 12, the U.S. Army Corps of Engineers reportedly conceded that there may be a new hurdle on the horizon for Pebble Mine permitting.

On Feb. 6, the environmental group Center for Biological Diversity filed a lawsuit seeking Endangered Species Act protection for Lake Iliamna harbor seals, one of only two harbor seal populations living exclusively in fresh water, whose population now numbers about 400, according to the center.

“Alaska’s unique and imperiled freshwater seals need federal protection,” said Kristin Carden, a scientist at the Center for Biological Diversity. “The Pebble Mine threatens the very survival of the Iliamna Lake seals and the fish species they depend on to survive. Even if the mine is stopped, climate change will drive these rare and beautiful animals toward extinction.”

Subsistence hunters in the region harvest lake seals. The center advises that its lawsuit would not interfere with subsistence hunting or fishing by Alaska natives. Whether it may affect commercial fisheries in Bristol Bay remains to be seen.

Researchers Return to Study Gray Seal Pups in New England

February 6, 2020 — The following was released by NOAA Fisheries:

It’s gray seal pupping season in New England! NOAA researchers are working with colleagues to gather data from pups on Muskeget and Monomoy islands off the southeastern Massachusetts coast.

Pupping season generally runs from mid-December to early February, peaking in mid-January. Our researchers have conducted studies of animal abundance, distribution, and health on the islands in January for the past eight years. One research team is working on Muskeget Island off Nantucket, the largest gray seal breeding and pupping colony in the United States. Another team is on Monomoy, an island near Chatham on Cape Cod that is part of the Monomoy National Wildlife Refuge.

Kimberly Murray, who coordinates the seal research program at the Northeast Fisheries Science Center’s Woods Hole Laboratory and leads the team on Muskeget Island, outlined the teams’ goals. “We plan to place 20 satellite tags and nine acoustic tags on the weaned gray seal pups, and to collect as many health samples from pups as we can. Our goal is to sample 50 pups on Muskeget and 100 on Monomoy, but that depends on factors such as weather conditions, scheduling, and departure of weaned pups.”

The team also sampled 14 weaned gray seal pups on Seal Island in Maine. They placed five satellite tags and two acoustic tags on seal pups there to learn where those pups go. On January 30 researchers sampled and tagged 15 gray seal pups on the Coskata-Coatue Wildlife Refuge, which includes Great Point Light, on Nantucket and collected scat or seal poop for microbiome/microplastics/food habits work.

US biologists eye unusual deaths of Alaska ice seals

September 13, 2019 — Seals that rely on sea ice off Alaska’s northwest coast have been dying at uncommon rates, and federal marine mammal biologists Thursday declared an “unusual mortality event.”

The cause of death for nearly 300 ringed, bearded and spotted seals since June 1, 2018, is not known, according to the fisheries arm of the National Oceanic and Atmospheric Administration, the management agency for the marine mammals.

“We’re looking at a broad spectrum of possible causes and trying to rule out what we can and narrow it down,” NOAA Fisheries spokeswoman Julie Speegle said.

Viruses, bacteria and algal blooms are possible causes. Water temperature in the northern Bering Sea and the Chukchi Sea the last two summers have been higher than normal. The agency is looking at possible ecosystem influences, including diminished sea ice, Speegle said.

Alaska Native coastal communities hunt all three seals for meat and hides as part of a subsistence life.
