December 8, 2025 — NOAA Fisheries has announced two new slow zones for right whales, including Cape Cod Bay. The restrictions are in place through December 20th after the whales were discovered last Friday. The other slow zone is east of Ocean City, Maryland, using a buoy that was operated partly by the Woods Hole Oceanographic Institution.

NOAA Fisheries report shows large whale entanglements nationwide up in 2024; 3 occurred in Maine
November 24, 2025 — According to a new annual report from NOAA Fisheries, there were 95 total confirmed large whale entanglements nationwide last year. In the Northeast Atlantic, the majority of entanglements were reported in Massachusetts Bay and Cape Cod Bay. Three occurred off the coast of Maine.
NOAA spokesperson Andrea Gomez says that two of those three whales were humpbacks, and one was a minke. One of the humpbacks was found dead outside of Portland, entangled in a fishing net. The other humpback and the minke were found alive off Jonesport and Stonington, entangled in Maine lobster gear. The minke was able to shed the gear on its own, and Maine Marine Patrol was able to disentangle the humpback.
Right whale often seen in Cape Cod Bay spotted with newborn calf
February 24, 2024 — An endangered North Atlantic right whale that’s been frequently sighted in Cape Cod Bay was recently seen swimming with her new calf down south.
“Skittle” and her calf were spotted east of Kure Beach in North Carolina on Feb. 16. Skittle is often seen swimming in Cape Cod Bay in March.
It’s believed Skittle is at least 23 years old and gave birth to her first calf in 2010, but that calf likely did not survive. The New England Aquarium explains that Skittle gets her name from her skin pattern that resembles a bowling pin used in the British sport of Skittles.
MASSACHUSETTS: Lobstermen Face Hypoxia in Outer Cape Waters
August 17, 2023 — Alex Iacono, a lobsterman who says he favors lobsters and ocean solitude over people, is worried about the future of his business. Iacono, who lives in Truro and fishes out of Provincetown on the F/V Storm Elizabeth, says his catch has significantly dwindled in recent years.
He’s not alone; other lobstermen working across Cape Cod Bay have noticed a downward trend. They believe that hypoxia — dangerously low levels of oxygen in the water — is to blame.
On Aug. 11, local lobster fishermen were advised by the Div. of Marine Fisheries (DMF) that low levels of dissolved oxygen had been recorded in two areas: at the southern end of Cape Cod Bay near Barnstable and here, in the waters between Provincetown and Wellfleet.
Hypoxia first came to fishermen’s attention in 2019 when it caused a catastrophic lobster die-off in the bay. After that, the DMF started affixing sensors to buoys and traps to monitor oxygen levels, and they have consistently observed mild hypoxia since then.
Tracy Pugh, leader of the Invertebrate Fisheries Project at DMF, pioneered a “stoplight” color-coded hypoxia mapping system: green indicates areas with over 6 mg. of dissolved oxygen per liter of water; water with under 6 mg/L is coded yellow on the DMF map; orange signals mildly hypoxic water with less than 4 mg/L; and red indicates severely hypoxic water, with less than 2 mg/L of dissolved oxygen.
Right whales stay in Cape Cod Bay longer, and later
June 16, 2022 — It isn’t high gas prices that changed the travel plans of right whales.
A new study in Global Change Biology by nine authors discovered that over the last couple of decades North Atlantic right whales are most active in Cape Cod Bay 18 days later than before.
That’s a shift — with a longer stay in the month of May — that could potentially bring the whales further into conflict with the region’s annual boating and lobster season and require an extended season of protections.
“The state has a flexible rule in place — where they can extend fishing closures and small boat speed restrictions — that now is in place up the coast to New Hampshire,” the study’s lead author, Dan Pendleton of the New England Aquarium, said. “Massachusetts Bay has seen more right whales than it used to.”
“One of the problems with migratory animals is they can get into big trouble moving into shipping lanes so if we can move and adapt the protections as (whales) adapt to climate change, that would be ideal,” Pendleton said. “So much seems out of our control but one thing we can do is push for regulations that are responsive to the needs of an endangered species.”
Beth Casoni, executive director of the Massachusetts Lobstermen’s Association, hadn’t yet seen the study, which was published June 7. Casoni said, therefore, she couldn’t comment until she has been able to read it.
Warming water pushes endangered whale toward deadly boats
June 15, 2022 — North Atlantic right whales are some of the most endangered marine mammals on the planet. Threatened by shipping collisions and tangles with fishing nets, fewer than 400 individuals are thought to exist in the wild today.
Now, scientists are adding climate change to its list of dangers.
Recent studies suggest that warming ocean waters are shifting the tiny crustaceans that right whales like to eat, causing them to multiply at different times of the year and move into new parts of the ocean. As the whales follow their prey, they’re abandoning some of their old feeding grounds, migrating into some new ones and arriving in some places earlier or later than they would usually be expected.
As a result, scientists warn, they’re showing up in spots that don’t necessarily have adequate protections in place for them. That may increase their risk of running into ships or nets.
A new study, out last week in the journal Global Change Biology, is the latest to raise the alarm.
The research finds that right whales are changing the way they move through Cape Cod Bay, one of their preferred spring foraging grounds. They’re using the habitat more heavily than they did in the past and their peak numbers are shifting later in the season.
New research shows climate change impacts on whale habitat use in the warming Gulf of Maine
June 10, 2022 — New research finds climate change is having an impact on how large whale species, including the critically endangered North Atlantic right whale, use habitats in the warming Gulf of Maine, showing that right whales’ use of Cape Cod Bay has shifted significantly over the last 20 years.
The study, led by the New England Aquarium and including researchers from the University of Massachusetts Amherst, the USGS Northeast Climate Adaptation Science Center, the Center for Coastal Studies, UCLA, the National Marine Fisheries Service, and the Canadian Whale Institute was published this month in the journal Global Change Biology. The authors set out to better understand the impacts of ocean climate change on phenology, or the timing of recurring biological events such as when plants flower each year. Using more than 20 years of data, the scientists measured shifts in whale habitat use in Cape Cod Bay, evaluating trends in peak use for North Atlantic right whales, humpback whales, and fin whales. The study found that peak use of Cape Cod Bay had shifted almost three weeks later for right whales and humpback whales. Changes in the timing of whale habitat use were related to when spring starts, which has been changing as a result of climate change. The study suggested that highly migratory marine mammals can and do adapt the timing of their habitat use in response to climate-driven changes in their environment, with results showing increased habitat use by right whales in Cape Cod Bay from February to May, with greatest increases in April and May.
“The time of year when we are most likely to see right and humpback whales in Cape Cod Bay has changed considerably, and right whales are using the habitat much more heavily than they did 20 years ago,” said lead author Dr. Dan Pendleton, Research Scientist in the New England Aquarium’s Anderson Cabot Center for Ocean Life.
Rare Right Whale Sightings Reported Along New England Shoreline
May 24, 2022 — Several people have reported rare sightings of North Atlantic Right Whales this month along the New England coastline from Provincetown to Portsmouth.
“It is pretty rare to see them that close to shore,” Heather Pettis of the New England Aquarium said.
With its bristle-like baleen plates and distinctive callosities decorating its head to its massive size and characteristic tail flukes, the North Atlantic Right Whale has been entertaining New Englanders this spring with some shoreline shows.
“Sure enough, there was a right whale skim feeding right off of Route 1A,” Pettis said. “This time of year whales sort of leave Cape Cod Bay, where they’ve been feeding over the winter. They disperse and we have these opportunistic sightings pop up.”
MASSACHUSETTS: Whale Rescued in Cape Cod Bay a Decade Ago Spotted with Calf
December 29, 2020 — A right whale rescued in Cape Cod Bay a decade ago was recently spotted with a newborn calf in the waters off of North Carolina and Florida, a good sign for the critically-endangered marine animal.
The Center for Coastal Studies said that the calf was one of the first two right whales of the 2021 season, and the mother is right whale #4040, Chiminea.
Chiminea was found entangled in Cape Cod Bay by the Center’s aerial survey team in April 2011, in the waters west of Truro.
The Marine Animal Entanglement Response team cut the entangled then-juvenile whale free of a long line caught in the mouth, after which she swam away free.
MASSACHUSETTS: Seasonal Ban on Lobstering Aims to Protect Right Whales
December 21, 2020 — With the North Atlantic right whale population at a dangerously low ebb, the state Division of Marine Fisheries is proposing a statewide seasonal ban on lobstering in a last-chance effort to save the critically endangered species from extinction.
Floated by the DMF during public hearings on Dec. 8 and 9, the proposed regulations come in the wake of a report that estimated right whale populations at only 366 marine mammals — down from the 481 estimated in 2011 — and a continued “unusual mortality event” that has seen more than 30 right whale deaths in the past three years.
The dramatic rule changes propose extending the state’s existing Feb. 1 through April 30 lobster trap closure in Cape Cod Bay to all waters under the jurisdiction of the commonwealth, including the Vineyard and Nantucket Sound. Buoyed recreational lobster and crab trap fishing would also be closed. The recreational closure would run from the Tuesday after Columbus Day through the Friday preceding Memorial Day.
