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.

Right whales’ survival rates plummet after severe injury from fishing gear

June 14, 2022 — Most North Atlantic right whales that are severely injured in fishing gear entanglements die within three years, a new study led by scientists at the New England Aquarium and Duke University finds.

North Atlantic right whales are a critically whose population has shrunk in recent decades. Scientists estimate fewer than 350 of the iconic whales are still alive in the wild today.

To examine the role entanglements have played in the species’ decline, the researchers tracked the outcomes of 1,196 entanglements involving 573 right whales between 1980 and 2011 and categorized each run-in based on the severity of the injury incurred

The data revealed that male and female right whales with were eight times more likely to die than males with minor injuries, and only 44% of males and 33% of females with severe injuries survived longer than 36 months.

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.

New restrictions on ships to protect whales coming soon

June 10, 2022 — Federal authorities spent the past few years analyzing rules for the shipping industry and are now close to releasing fresh guidelines to help protect a vanishing species of whale.

The National Oceanic and Atmospheric Administration has been reviewing the speed regulations it uses to protect North Atlantic right whales, and according to spokesperson Allison Ferreira, the agency will publish new proposed rules within the coming weeks. A public comment process would follow.

Environmentalists have long pushed for stricter shipping rules to protect the whales, which number less than 340 and are vulnerable to collisions with large ships. They’ve fallen in population in recent years due to high mortality and poor reproduction.

New federal regulations on lobster fishing in effect, aimed at protecting endangered whale species

June 9, 2022 — Statistics from the National Oceanic and Atmospheric Administration show less than 350 endangered North Atlantic Right Whales still exist. The new regulations that went into effect for fishermen on May 1 aim to help those numbers increase.

Besides closures – which dictate specific areas in federal and state waters where fishermen cannot fish during certain times of the year due to whale activity – it also includes the need for using weak rope that breaks on contact.

Fishermen also have to mark gear so if it does get wrapped around a whale, it can be identified.

“This is actually weak rope, but I actually have to have a one-foot green mark on it,” Rob Martin said. Martin has been lobster fishing in these waters off Cape Cod in Massachusetts for more than four decades.

He said changing the rope and following the new regulations takes time.

“It’s a lot of man-hours to do,” Martin said.

Lobster industry and lawmakers await court decision to determine legality of new restrictions

June 8, 2022 — Maine and Massachusetts harvest more than 90% of the American lobsters sold in the U.S. and most lobstermen and New England lawmakers want to keep it that way.

Over the past year, a dispute over new federal regulations on Maine’s lobster industry, intended to protect the endangered North Atlantic Right Whale, have become heated as Maine’s lobster industry fights to protect the livelihoods of its workforce.

Mike Sargent, who became the captain of his own boat at 15, told Spectrum News Maine that things haven’t been too bad since the restrictions went into effect in May.

“Yes, it’s an added expense and something I’ll look into as I rewrite my business model for this year and for years in the future. But, it’s not a deal breaker yet,” said Sargent, who grew up in Milbridge and is now part of an advocacy campaign called Lobster from Maine.

The 29-year-old is worried, however, that if regulations adopted by the National Oceanic and Atmospheric Administration in 2021 are ruled lawful by the U.S. District Court of the District of Columbia, that more expensive and stricter regulations could follow.

Agreement Reached to Protect Whales Amid Marine Wind Projects

June 6, 2022 — The New England Aquarium recently announced that it is partnering with Cornell University and wind energy consultant LAUTEC US on a project to better assess the relationship between offshore wind developments and the habitats of critically endangered North Atlantic Right Whales.

Although the full impact of wind development on whales is unknown, pile driving activities associated with offshore wind projects could potentially force whales from their habitat and disrupt important behaviors such as feeding and socializing.

New England lobster, crab boats could begin using experimental ropeless gear with federal permits

June 6, 2022 — Federal fisheries officials are proposing a special permit to allow up to 100 New England lobster and crab boats to use experimental high-tech systems to retrieve their traps. That would mark a big expansion in the development of fishing systems that could help protect endangered North Atlantic right whales.

The technology uses remote-control systems to locate and trigger traps or buoy lines to the surface, reducing the use of vertical rope lines that can entangle the right whales.

Henry Milliken supervises a prototyping program for the so-called “ropeless” gear at the Northeast Marine Fisheries Science Center in Woods Hole.

New project aims to protect whales while developing offshore wind energy

June 3, 2022 — A new partnership between conservation and renewable energy is coming to Massachusetts.

The Right Wind project, through the combined efforts of the New England Aquarium, Cornell University, and LAUTEC US, aims to help offshore wind developers protect the North Atlantic right whale.

“We’re excited to be starting this project because it gives us an opportunity to develop tools that can help reduce the potential risks of wind energy development to North Atlantic right whales, a critically endangered species that numbers less than 350 individuals,” said Dr. Laura Ganley, an associate research scientist at the New England Aquarium.
