MASSACHUSETTS: Great White Shark Numbers Increasing On Cape Cod

May 26, 2017 — We’re getting close to that time of year, when the great white sharks make their annual visit to the waters of Cape Cod. Cape Cod is the only known aggregating site for white sharks in the North Atlantic.

According to the latest study by the Massachusetts Division of Marine Fisheries, the number of great white sharks vacationing there appears to be rising. That’s a public safety issue for towns, according to the state’s top shark expert.

Interview Highlights

On their survey of the numbers of great white sharks

“We are right in the middle of a 5-year population study … what I can tell you … is how many individuals we’ve tabulated year for the last couple of years. In 2016 for example, we identified 147 individual white sharks along the Eastern shoreline of Cape Cod. The year prior to that, it was 141 and the year prior to that in 2014, it was about 80. So we’re seeing that subtle increase from year to year. And as tempted as I am to say that it’s actually an increase in the population size, it’s more likely a shift in the distribution of sharks in response to the growing seal population.”

On how the seals are attracting sharks

“Most people don’t realize the interesting history of the seal populations on the Northeastern coast of the U.S. They had been all but drive to extinction a couple of hundred years ago. And now, with protection that was put in place in the early 1970s, we’ve seen the slow growth in the population that has now resulted in literally tens of thousands of seals along our coastline. And that has drawn the attention of one of their predators, the white shark.”

REMINDER: No Selfies with Seals!

May 26, 2017 — The following was released by NOAA:

Seal pupping season is underway in New England. If you are headed to the beach this Memorial Day weekend, you might see a seal pup resting on the beach.

There is no selfie stick long enough!

As tempting as it might be to get that perfect shot of yourself or your child with an adorable seal pup, please do the right thing and leave the seal pup alone. Getting too close to a wild animal puts you–and the animal-at risk. 

Seals have powerful jaws, and can leave a lasting impression. 

We have received reports of (and seen on social media) numerous injuries to humans as a result of getting too close to an animal during a quick photo op. When you get too close to a wild animal, you risk stressing or threatening it, and stressed animals are much more likely to act unpredictably. 

Normal Behavior

It is normal for a mother seal to leave her young pup alone on the beach for up to 24 hours while she feeds. You may not see the mother offshore, but if she sees you near her pup, she may not think it’s safe to come back. It might only take a few seconds for you to snap the photo, but the mother may abandon her pup if she feels threatened. For the seal pup, the consequences can be devastating.

Give Them Space

If you see a seal pup, keep your distance. As a rule of thumb, stay at least 50 yards (150 feet) from seals. A curious seal pup might approach on its own, but the mother is likely to be nearby, and may see your interaction as a threat.

“The best thing you can do if you want to help is keep away from the animal and keep your pets away from it, so the mother has a chance to return,” says Mendy Garron, marine mammal stranding program coordinator for NOAA Fisheries Greater Atlantic Region.

The Rules

Approaching a wild animal can be considered harassment, which is an illegal activity. Under the Marine Mammal Protection Act of 1972, harassment is defined as “any act of pursuit, torment, or annoyance” which has the potential to injure or disturb a marine animal. This can be dangerous for the animal, but can be dangerous for you, too.

How to Help

If you think an animal may be in trouble, there are things you can do:

  • To report a stranding, please call your local Marine Mammal Stranding Network Member or the NOAA Fisheries Northeast Regional 24-hour hotline 866-755-NOAA (6622).
  • If you see someone harassing a marine mammal, please contact our Office of Law Enforcement at 800-853-1964.
  • Always maintain a safe distance, at least 150 feet, from the animal to avoid injury to yourself or injury to the animal.

Endangered Hawaiian monk seal population rises to 1,400

January 25, 2017 — HONOLULU — The population of Hawaiian monk seals — one of the world’s most critically endangered marine mammals — has been increasing 3 percent a year for the past three years, federal wildlife officials said Tuesday.

There are now about 1,400 of the seals in the wild, said Charles Littnan, lead scientist of the Hawaiian Monk Seal Research Program at the National Oceanic and Atmospheric Administration.

“This is phenomenal, hopeful news for the population,” Littnan told reporters. “Yet we have a long way to go to recovery.”

The population has experienced increases in the past, including the mid-2000s, but Littnan characterized those as minor blips.

Hawaiian monk seals declined in numbers for years, most recently as juveniles struggled to compete for food with large fish and sharks in the remote Northwestern Hawaiian Islands, a mostly uninhabited stretch of tiny atolls that includes Midway.

Strange visitor from the South (a manatee) is spotted off Cape Cod

August 30, 2016 — To the thousands upon thousands of seals that populate isolated beaches, and the frenzy of great white sharks that have frightened swimmers, now add another creature of the sea: an oddly graceful, roughly 8-foot-long manatee that has probably arrived from Florida to join the throngs of tourists enjoying the warm waters off Cape Cod.

Since mid-August, wildlife experts have documented at least a half-dozen sightings of the transient manatee they believe slowly swam up the East Coast to feed on local vegetation.

He or she still appears intent on taking in popular spots along the Cape, like any vacationer. The issue it faces is one of time: When the water temperatures drop, its chances of survival do, too.

Bill Pouliot and his son, Brayden, saw the wayward manatee while fishing on Bridge Street in Chatham Sunday. When the buoyant gray object came into view, they couldn’t believe its size.

“It was gi-normous,” said the elder Pouliot, mashing together the words “giant” and “enormous” to best describe the girth of the unexpected guest.

At first, both father and son thought the rotund animal spotted foraging on sea grass was a seal that wandered off from its beachy haunts.

But as they further examined the marine creature lazily floating nearby, they concluded it was something else entirely.

“It was just sort of going down to the bottom to eat, and then coming back up, perhaps sunbathing,” Pouliot said.

Study predicts alarming krill drop by end of the century

August 30, 2016 — Antarctic krill (Euphausia superba) habitat is undergoing a continuous deterioration process, which could lead to a reduction of up to 80 per cent by the end of the century.

Given the key role that this small crustacean plays in the marine food chain, its decline would cause other problems for species that depend on it as a food source, such as whales, penguins, seals, squid and fish, among other marine organisms.

This dark forecast comes from a study performed at Yale University by Andrea Piñones, a researcher at the Research Centre for High Latitude Marine Ecosystem Dynamics (IDEAL) and the Advanced Study Centre in Arid Zones (CEAZA), along with Alexey Fedorov, a researcher at Yale University.

Piñoness explains that the krill population has already fallen between 80 and 90 per cent since 1970, a situation that has generated a broad scientific debate on the causes of this decline.

In this regard, many believe that this is related to the changes in the environment, particularly with warming Antarctic waters.

To carry out the study, whose results were published in the journal Geophysical Research Letters, the researchers combined climate simulations — based on the projections of the international panel of climate change –, with a krill growth model. Thus, they determined that with an increase in water temperature and sea ice melting, its habitat could reduce up to 80 per cent by 2100.

Cutback mulled for herring catch

June 23, 2016 — PORTLAND, Maine — Federal regulators are considering a slight cut to commercial fishermen’s catch limit for Atlantic herring, a fish that is important both to the industry and the ocean’s food web.

The small fish gather in schools that can number in the millions, and are a critical food source for bigger fish, seals and whales. They also are important to humans as food and bait.

The National Marine Fisheries Service might reduce the herring catch limit by about 3 percent to slightly less than 105,000 metric tons. The limit was a little less than 108,000 metric tons for the 2013 to 2015 period; any new limit would apply to the years 2016 to 2018.

The proposal is up for public comment until July 21.

Scientists turn to drones to count growing seal colonies

March 7, 2016 — On a remote island off of Nantucket, scientists are using a tool most commonly associated with war and surveillance to get a look at fuzzy baby seals.

Researchers who want to get a handle on the growth of New England’s gray seal population have been using drones as part of an effort to photograph the animals, which gather in huge numbers on remote islands.

The National Oceanic and Atmospheric Administration used a pair of unmanned aircraft on Muskeget Island off of Massachusetts to take pictures of seal pups in January. The island is the biggest gray seal breeding colony in the country.

The pictures will help scientists find how many gray seals there are in Northeastern waters, said Kimberly Murray, the coordinator of the seal research program at NOAA’s Northeast Fisheries Science Center.

“We need to know how many seals there are before we can know what’s going on, and how to manage them. Or, I should say, manage us,” Murray said.

Climate change hurting New England cod population, study says

October 29, 2015 — The rapid warming of the waters off New England has contributed to the historic collapse of the region’s cod population and has hampered its ability to rebound, according to a study that for the first time links climate change to the iconic species’ plummeting numbers.

Between 2004 and 2013, the mean surface temperature of the Gulf of Maine — extending from Cape Cod to Cape Sable in Nova Scotia — rose a remarkable 4 degrees, which the researchers attributed to shifts in the ocean currents caused by global warming.

The study, which was released Thursday by the journal Science, offers the latest evidence of climate change — this time, affecting a species once so plentiful that fishermen used to joke that they could walk across the Atlantic on the backs of cod.

Fisheries management officials have sharply limited cod fishing in hopes of protecting the species, but they estimate the number of cod remain at as little as 3 percent of what would sustain a healthy population. The limits, in turn, have hurt fishermen.

“Managers [of the fishery] kept reducing quotas, but the cod population kept declining,” said Andrew Pershing, the study’s lead author and chief scientific officer of the Gulf of Maine Research Institute in Portland. “It turns out that warming waters were making the Gulf of Maine less hospitable for cod, and the management response was too slow to keep up with the changes.”

The institute had reported last year that the rise in temperatures in the Gulf of Maine exceeded those found in 99 percent of the world’s other large bodies of saltwater. The authors of Thursday’s study link the rapid warming to a northward shift in the Gulf Stream and changes to other major currents in the Atlantic and Pacific oceans.

They say the warmer water coursing into the Gulf of Maine has reduced the number of new cod and led to fewer fish surviving into adulthood. Cod prefer cold water, which is why they have thrived for centuries off New England.

The precise causes for the reduced spawning are unclear, the researchers said, but they’re likely to include a decline in the availability of food for young cod, increased stress, and more hospitable conditions for predators. Cod larvae are View Story eaten by many species, including dogfish and herring; larger cod are preyed upon by seals, whose numbers have increased markedly in the region.

NOAA Awards $2.75 Million for Marine Mammal Rescue Efforts

September 10, 2015 — The following was released by NOAA:

Today, NOAA Fisheries announced the award of $2.75 million in grant funding to partner organizations in 16 states to respond to and rehabilitate stranded marine mammals and collect data on their health. The John H. Prescott Marine Mammal Rescue Assistance Grant Program provides funding to non-profit and for-profit organizations, academic institutions, and state agencies that are members of the National Marine Mammal Stranding Network.

“Prescott grants help our national marine stranding response teams continue to improve their techniques, and supports our efforts to establish links between the health of marine mammals, coastal communities and our coastal ecosystems,” said Dr. Teri Rowles, NOAA Fisheries lead marine mammal veterinarian and coordinator of the Marine Mammal Health and Stranding Response Program. “The money supports vital information needed to protect and conserve whales, dolphins, seals, and sea lions.”

“Prescott grants tie directly to NOAA Fisheries’ core mission, which includes the conservation, protection and recovery of protected marine resources, including whales, dolphins, seals and sea lions,” said Eileen Sobeck, assistant NOAA administrator for fisheries. “Helping our stranding partners do their jobs on the front lines of response and rehabilitation fits in perfectly with our goals.”

The Stranding Network is comprised of trained professionals and volunteers from more than 100 organizations that partner with NOAA Fisheries to investigate marine mammal strandings, rehabilitate animals, and assist with research on marine mammal health issues. NOAA Fisheries relies on its long-standing partnership with stranding network members to obtain the vital research about marine mammal health needed to develop effective conservation programs for marine mammal populations in the wild.

Since the Prescott Grant Program’s inception in 2001, NOAA Fisheries has awarded 518 Prescott grants to members of the National Marine Mammal Stranding Network, totaling more than $45.5 million. Over the years, Prescott grants have enabled members to improve operations, such as expanding response coverage, enhancing response capabilities and data collection, and improving rehabilitation of marine mammals.

Prescott Grants are made under Title IV of the Marine Mammal Protection Act, which authorizes NOAA Fisheries to fund eligible members of the National Marine Mammal Stranding Network through grants and cooperative agreements.
