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.

MASSACHUSETTS: Lobster season opens on time after right whales move out of Cape Cod bay

May 1, 2020 — Lobster season for the South Shore will begin as planned after endangered right whales, spotted in Cape Cod Bay, moved out of the area.

The Provincetown Center for Coastal Studies estimated five whales, including two mother-and-calf pairs, were feeding in Cape Cod Bay, following an aerial survey on April 25. On Wednesday, another aerial inspection over the area found the whales had moved out of the bay and adjacent waters, the Massachusetts Division of Marine Fisheries said in an announcement Thursday afternoon.

The Division previously extended the opening of the season to May 8 because the whales were spotted, spokesman Craig Gilvarg said in a statement. North Atlantic right whales are an endangered species and vulnerable to buoy entanglement and getting hit by boats, because they feed near the surface.

“Everybody is anxious to go,” John Haviland, president of the South Shore Lobster Fishermen’s Association, said. “They’ve been standing around for three months, basically in quarantine.”

Group Discusses Potential Gear Restrictions At North Atlantic Right Whale Consortium

November 15, 2019 — An international group of scientists, conservationists, fisheries managers and others are gathered in Portland this week for the annual meeting of what’s called the North Atlantic Right Whale Consortium.

Federal regulators told the group that they are looking at a wide slate of measures to protect the endangered whales from entanglement in fishing gear. Some measures include reductions in the amount of lobster-trap rope allowed in the water and in the strength of that rope. The feds say they are also considering having a part of Cape Cod Bay that is now closed February to April closed to endlines but open to ropeless gear in the future.

Researchers Report Spike in Ocean Sunfish Strandings

November 8, 2019 — Marine researchers are reporting a spike in sunfish strandings this fall as waters continue to cool off Cape Cod.

Ocean sunfish, also known as mola mola, is one of the heaviest known bony fishes in the world. Adult sunfish typically weight between 550 and 2,200 pounds.

It is a unique shape and resembles a fish head with a tail and has a mainly flat body.

As the sunfish are migrating south to warmer waters they can get trapped and cold stunned, mainly in Cape Cod Bay, similar to what happens with sea turtles.

Marine biologist Carol “Krill” Carson, the president of the New England Coastal Wildlife Alliance, said sunfish strandings average between 20 and 40 per season, and there have been 135 carcasses documented this year.

“This year is our busiest season and we have exceeded all previous seasons already,” Carson said. “The stranding season hasn’t even ended.”

The sunfish stranding season typically runs from mid-August through the end of December.

“It’s been a really bad season for ocean sunfish,” Carson said.

MASSACHUSETTS: Right whales extending their stays in Cape Cod Bay

May 21, 2019 — With the count of North Atlantic right whale sightings in Cape Cod Bay down to zero Thursday, the end-of-season findings by the Center for Coastal Studies indicate what could be new realities: More animals are showing up each year, and the length of time they’re staying in the bay is longer.

“There are two trajectories,” said Charles “Stormy” Mayo, the center’s right whale ecology program director. “Our trajectory is going up while the total number of right whales is going down, fairly steeply.”

The center has studied the right whales in the bay for several decades, currently with airplane surveys for population counts and boat surveys to identify food densities in the water. The data collected is used, in part, to help the state Division of Marine Fisheries place and lift restrictions in the bay on trap gear fishing and vessel speeds.

The right whales — now considered at risk of extinction in the coming decades along the Atlantic coast due to deaths and injuries from being caught in fishing rope and hit by ships — have a current population of around 411. They typically arrive to feed in Cape Cod Bay in late winter and leave by the end of April, along an annual migratory path that stretches from Florida to Canada.

So far, the center has confirmed 267 individual right whales seen by either plane or boat for the current season, making that roughly 65 percent of the estimated total population. Considering the complete range of the whales’ migration along the East Coast, the concentration in the relatively small area known as Cape Cod Bay is “remarkable,” Mayo said.
