North American lobster industry confronts 'ropeless' traps after whale
entanglements

MONHEGAN ISLAND, Maine (Reuters) - An emerging technology to fish for
lobsters virtually ropeless to prevent whale entanglements is exciting
conservationists, but getting a frigid reception from harvesters worried
it will drive them out of business and upend their way of life.
Injuries to endangered North Atlantic Right Whales ensnared in fishing
gear have fueled a prominent campaign by environmental groups to
pressure the industry to adopt on-demand equipment that only suspends
ropes in the water briefly before traps are pulled from the water.
The Monterey Bay Aquarium’s Seafood Watch, which assesses the
sustainability of fisheries, has put lobsters on a red list citing the
threat to whales from ropes, prompting retailers like Whole Foods to
stop selling them.
But lobster harvesters along the North American coast are less than
impressed with idea of adopting the new gear. They argue it's expensive,
faces the risk of technological glitches - and ultimately, does little
for whales.
"My guess is for a lot of Maine lobstermen it is just a really scary
idea," said Matt Weber, a lobsterman from Monhegan Island in Maine. "And
it is all the more scary because none of us feel it is going to help
(the whales)."
Since the start of the year, four North Atlantic Right Whales have been
injured after getting entangled in fishing rope, according to government
data, including one filmed in North Carolina trailing a pair of lobster
traps that U.S. authorities believe came from the Canadian province of
Nova Scotia hundreds of miles away.
Such entanglements have killed at least nine North Atlantic Right Whales
since 2017, making it the second biggest cause of death behind strikes
from boats and ships, according to the National Oceanographic and
Atmospheric Administration.
That is a large number, given there are fewer than 350 North Atlantic
Right Whales remaining, including just 70 breeding females, say
regulators, researchers and conservationists. North Atlantic Right
Whales who live off the eastern North American coast stretching from
Florida to the Canadian Maritimes provinces are now on the verge of
extinction.
To address the problem, the U.S. and Canadian governments have imposed
new regulation on lobster and crab fisheries in recent years, including
the use of weak links in rope that break if a whale swims through,
color-coded rope for tracing, adding more traps per buoy line, and zone
closures during whale migration.
But whales are still getting entangled.
“It doesn’t look like the solutions we’ve come up with are effective,”
said Charles Mayo, senior scientist at the Center for Coastal Studies in
Cape Cod, Massachusetts.
"Not effective to the point we need. We need a growing population. We
don’t have that many whales left.”
Washington and Ottawa are now promoting ropeless fishing as a possible
long-term solution. Traditional lobster fishing uses traps that sink to
the ocean floor and are connected by a rope to a buoy floating at the
surface. Ropeless gear, by contrast, only deploys a rope and buoy to the
surface when its owner activates a release trigger by remote control.
NOAA published a strategy document in 2022 that envisions potential
regulations for ropeless technology in coming years, and Canada’s
Fisheries department has called ropeless gear “the only way you
eliminate the vertical line entanglement risk.”
'DRASTIC OVER-RESPONSE'
Rob Morris, a product line sales engineer for Edgetech, one of the
handful of companies working on ropeless traps, said most of the
technical issues around the equipment have been resolved – including
reliability, viewing submerged gear on a chart plotter, and avoiding
other people’s traps.

"This is pretty much fully developed,” he said. “We’re just making
tweaks at this point.”
He said Edgetech was ready to make 100 units a month and was just
waiting for industry orders.
But lobstermen, particularly in Maine where 80% of U.S. lobster is
caught, are not enthusiastic.
The industry has long argued that not a single North Atlantic Right
Whale death has been attributed to Maine lobster gear, and that the
whales’ current migratory path puts them well east of the state’s
lobster fishing grounds.
Lobster harvesters are also reeling from a public backlash due to
whale entanglements and the red-listing by Seafood Watch last year,
which marks a stunning fall from grace for an industry praised for
decades for its sustainable practices.
“This seems to be a drastic over-response to something that didn’t
happen here,” said lobsterman Kyle Murdock of Monhegan.
Lobstermen say they are concerned about the high overhead costs of
switching to ropeless equipment, and fear inevitable technical
glitches that could result in tens of thousands of dollars of traps
lost at the bottom of the sea.
“I suppose there are lobstermen that would go ahead and do it and
would invest the money. But I think it would be the end of Maine
lobstering as we know it,” said Weber.
A handful of New England lobstermen are piloting ropeless equipment
under special permits, mainly in Massachusetts. None of those
lobstermen contacted by Reuters agreed to be interviewed.
CANADIAN TROUBLE
In 2017, North Atlantic Right Whales began showing up in numbers in
an unusual spot, Canada’s Gulf of St. Lawrence, east of where they
normally would be seen.
Scientists say the shift from the usual summer destination of the
Bay of Fundy was due to new currents, driven by climate change, that
had pushed the whales’ food – small crustaceans called copepods – in
that direction.
The result was tragic for the whales. Feeding in the midst of the
Gulf’s busy shipping lanes and active snow crab and lobster
fisheries, North Atlantic Right Whale deaths surged to 15 in that
year alone, with five attributed to vessel strikes and the rest to
either entanglements or unknown causes.
Brett Gilchrist, director of Fisheries and Oceans Canada, said
Ottawa immediately implemented new measures to protect the whales,
reducing ship speeds, and requiring the fishing industry to use weak
rope links in their lines.
The government also began aerial and acoustic monitoring, allowing
it to close areas to fishing when a whale is spotted. When the 2,100
square-kilometer zones are shut, only harvesters with ropeless gear
are allowed to fish there, Gilchrist said.
“It's a bit of a challenge for our lobster harvesters for sure. But
they also see that they're in it for the long term and this will
help them secure their markets,” he said of the technology.
Michael Moore, a researcher at the Wood Hole Oceanographic
Institution in Massachusetts, said the whales’ unexpected arrival in
the Gulf of St. Lawrence showed how vertical line fishing everywhere
might eventually have to adjust.
"As the climate changes, so too will the migration patterns," he
said. "My hope is that we can actually broker a mutually sustainable
solution to this problem. It is not impossible."
