American lobster show resilience amid climate change

September 12, 2024 — Experiments conducted at the Virginia Institute of Marine Science (VIMS) have shown that female American lobsters groom their offspring, and the grooming behaviors appear to remain stable despite the temperature and acidity conditions projected for Maine’s coastal waters by the end of the century. A study by researchers at William & Mary’s Batten School of Coastal & Marine Sciences shows that the species may be more resilient to the effects of climate change than previously thought.

The study examines how a changing climate may impact the reproductive success of species that brood or incubate and hatch their eggs. The findings were published in the journal Marine Ecology Progress Series and suggested that American lobsters can handle future ocean changes well, as their egg care and survival rates stayed stable under different conditions through the study’s tests.

Digging into the study

The study’s researchers partnered with the Maine Department of Marine Resources to obtain 24 lobsters from commercial operations for the study for five months. They secured female lobsters at market size with all legs intact, which are commonly lost in the wild.

Study offers hope for the resilience of the American lobster fishery

September 11, 2024 — According to a study by researchers at William & Mary’s Batten School of Coastal & Marine Sciences, the American lobster may be more resilient to the effects of climate change than expected. For the first time, experiments performed at the Virginia Institute of Marine Science (VIMS) have documented how female American lobsters groom their offspring, providing evidence that these behaviors are not significantly impacted by temperature and acidity levels forecasted for Maine’s coastal waters by the end of the century.

The findings are published in the journal Marine Ecology Progress Series.

Despite being one of the largest commercial fisheries in the U.S. with an annual economic impact of more than $460 million in Maine alone, few studies have documented the reproductive  of female American lobsters. With the Gulf of Maine warming faster than nearly any other ocean surface on the planet, it’s important to understand how the effects of climate change will impact the sustainability of the species and the fishery it supports.

“Brood grooming by female lobsters has been anecdotally observed, but it had not been quantitatively recorded before,” said Abigail Sisti, who is completing her Ph.D. in Marine Science at the Batten School and is lead author on the study. “In other crustaceans, these behaviors can have a significant impact on the survival of their offspring. Because the environment supporting the lobster fishery is rapidly changing, we wanted to understand how it might impact the way they care for their offspring.”

Female American lobsters can produce thousands of eggs that they hold under their tails for long periods of time, between five to 12 months, as the embryos develop. In other crustaceans, grooming behaviors help clear out parasites, remove dead eggs and facilitate the flow of water carrying oxygen and nutrients through the densely packed egg masses.

The study was part of a larger effort to determine how multiple stressors affect the reproductive success of the species. In this study, the researchers were testing whether increases in  and acidity had an impact on grooming behaviors and embryo survival.

Just how rare is a rare-colored lobster? Scientists say answer could be under the shell

September 9, 2024 — Orange, blue, calico, two-toned and … cotton-candy colored?

Those are all the hues of lobsters that have showed up in fishers’ traps, supermarket seafood tanks and scientists’ laboratories over the last year. The funky-colored crustaceans inspire headlines that trumpet their rarity, with particularly uncommon baby blue-tinted critters described by some as “cotton-candy colored” often estimated at 1 in 100 million.

A recent wave of these curious colored lobsters in Maine, New York, Colorado and beyond has scientists asking just how atypical the discolored arthropods really are. As is often the case in science, it’s complicated.

Lobsters’ color can vary due to genetic and dietary differences, and estimates about how rare certain colors are should be taken with a grain of salt, said Andrew Goode, lead administrative scientist for the American Lobster Settlement Index at the University of Maine. There is also no definitive source on the occurrence of lobster coloration abnormalities, scientists said.

“Anecdotally, they don’t taste any different either,” Goode said.

In the wild, lobsters typically have a mottled brown appearance, and they turn an orange-red color after they are boiled for eating. Lobsters can have color abnormalities due to mutation of genes that affect the proteins that bind to their shell pigments, Goode said.

Studies Look at Turbine Cables and Lobsters

September 5, 2024 — Two years after its first public announcement in August 2022, the Bureau of Ocean Energy Management (BOEM) plans to hold public auctions for eight offshore wind energy leasing areas in the Gulf of Maine this October.

During the public comment period ahead of the auction, BOEM received more than 100 comments, many of which mentioned the potential effects of floating wind turbines on the marine environment, seafood stocks, and commercial fishermen’s livelihoods.

One concern is the large power cables that will transfer electricity from the offshore wind turbines to the mainland. The power flowing through these cables generates electromagnetic fields, or EMFs, that some worry could disrupt the movement of lobsters across the seafloor or even affect their reproductive health.

Scientists who spoke with the Independent said that EMFs from offshore wind farms are not a cause for panic but do merit further investigation.

“Things aren’t just going to turn upside-down dead,” said Andrew Gill, a lead scientist at the U.K.-based Centre for Environment, Fisheries, and Aquaculture Science who has published research on the effects of undersea power cables on lobsters.

It’s important to address the concerns of fishermen with further studies, Gill added. “We need to identify what the concerns are and have the appropriately designed studies to help address them.”

New York lobster exporter accused of money laundering, collusion with Chinese government

September 4, 2024 — The owner of Forest Hills, New York, U.S.A.-based seafood company Foodie Fisherman has been charged with money laundering – among other crimes – and his wife, a New York political official, has been charged with taking payoffs in exchange for pursuing actions that benefited China.

On 3 September, Christopher Hu was arrested along with his wife, Linda Sun, who’s accused of acting as an agent of the Chinese government in her earlier role as an aide to former New York Governor Kathy Hochul.

What the Lobstermen of Maine Tell Us About the Election

August 26, 2024 — Mid-July is peak season on the central Maine coast. The blueberries — the small, low-bush kind long prized by the state’s jam makers and pie bakers — had started to appear in the farmers markets, along with the first of the tomatoes. Bright orange tiger lilies burst from front yards, while Queen Anne’s lace and goldenrod line the two-lane roads. The summer light dazzles, falling in soft waves upon the spruce and cedar, and brightening the paint on both midcentury saltboxes and grander Victorian homes. It’s no wonder that people want to come here.

Stonington is, without a doubt, one of the prettiest towns on the Maine coast. Over breakfast one morning at Stonecutters Kitchen, I asked Linda Nelson, the town’s economic and community development director, how many Hallmark movies had been filmed there.

“Not enough,” she replied.

Stonington also happens to be the largest lobster port in America. Dozens of fishing boats are anchored in the harbor, while lobsters caught in nearby Blue Hill, Jericho and Isle au Haut Bays are exported across the country and, more recently, across the globe. I was told by locals that not one of the beautiful wooden homes that form Stonington’s classic picture postcard view is owned by a fishing family, who now live elsewhere on Deer Isle or over the bridge on the mainland. From the perspective of a lobsterman, many of whom have deep Maine roots, the P.F.A.s — People From Away, as locals call them — are a presence to be tolerated. The lobster fishermen and the tourists and part-time residents coexist in two separate worlds, one that is changing beneath the surface.

In a significant political year, when a small group of voters in a few places will most likely shape the answers to pivotal questions about our government, how does a community living out climate change feel to its residents? This part of Maine is represented by a Democrat in Congress, but the district, Maine’s second, has voted for Donald Trump twice by decent margins; this is one of those places where every vote can matter. Here, the punishing demands of the present, how hard everyday work is, how important costs and prices are, make the pivotal nature of this time feel very distant from politics.

Feds announce funding push for ropeless fishing gear that spares rare whales

August 16, 2024 — New efforts to convert some types of commercial fishing to ropeless gear that is safer for rare whales will be supported by millions of dollars in funding, federal authorities said.

Federal fishing managers are promoting the use of ropeless gear in the lobster and crab fishing industries because of the plight of North Atlantic right whales. The whales number less than 360, and they face existential threats from entanglement in fishing gear and collisions with large ships.

The federal government is committing nearly $10 million to saving right whales, the National Oceanic and Atmospheric Administration said on Tuesday. Nearly $7 million of that will support the development of ropeless gear by providing funds to fishing industry members to assess and provide feedback on the technology, the agency said.

Lobster fishing is typically performed with traps on the ocean bottom that are connected to the surface via a vertical line. In ropeless fishing methods, fishermen use systems such an inflatable lift bag that brings the trap to the surface.

Game of inches: Lobster fishermen say tiny change in legal sizes could disrupt imperiled industry

August 14, 2024 — Gerry Cushman has seen Maine’s iconic lobster industry survive numerous threats in his three decades on the water, but the latest challenge — which might sound tiny — could be the biggest one yet.

Lobster fishing is a game of inches, and the number of inches is about to change. Fishing regulators are instituting a new rule that lobster fishermen must abide by stricter minimum sizes for crustaceans they harvest.

The impending change might be only 1/16th of an inch or 1.6 millimeters, but it will make a huge difference for fishermen when the fishery is already facing major threats from climate change and new rules designed to protect whales, numerous lobster fishers told The Associated Press.

Lobster fishery set for temporary reprieve on size limits

August 14, 2024 — A second delay to implementing minimum gauge and vent sizes for lobsters caught in the Gulf of Maine, Georges Bank and Outer Cape Cod was initiated last week by the American Lobster Board, which operates under the Atlantic States Marine Fisheries Commission (ASMFC), a measure that Maine lobstermen — and Congressman Jared Golden — have hoped and pushed for.

The new implementation date would be July 1, 2025, if the measure is approved by the ASMFC’s American Lobster Board.

An earlier delay the ASMFC approved had pushed back to Jan. 1, 2025, the new gauge and escape vent sizes in lobster traps for commercial lobster fisheries in the targeted lobster management areas. When the measure was first approved, it was to take effect based on a “trigger” mechanism.

The trigger is based on survey data showing a decrease of lobster recruits, that is, young lobsters. But many lobstermen fishing in the Gulf of Maine said what they observed on the water was different than the survey data reported. And, the first trigger was reached just months after the mechanism was approved, which led to the first implementation delay.

Lobster Habitat in the Gulf of Maine Has Changed, Scientists Say

August 13, 2024 — Lobster fishing has been a good business in the Gulf of Maine for a long time. With the exception of a few notable dips, both the landings and value of the catch have been on an upward swing for decades.

Between 1984 and 2014, the lobster population in the Gulf of Maine jumped an estimated 515%, while simultaneously declining by 78% in southern New England as the water warmed in both regions.

While it’s started to decline in recent years, numbers are still far higher than they were several decades ago.

The result? A lobster housing crisis.

“The warming sea temperatures have actually created a real sweet spot for lobster reproduction,” said Brian Skerry, a National Geographic photographer and producer on the recent GBH/PBS series Sea Change, which explores the impact of climate change on the Gulf of Maine.

Skerry, who lives in York, has been diving in the Gulf of Maine since childhood. But when he began diving on the Isles of Shoals for his most recent project, he saw something he’d never seen before: lobsters crawling all over the bottom, digging foxholes in the sand.

“I wasn’t used to seeing that,” said Skerry. “Usually they’re tucked away in rocky crevices and dens.”

Win Watson, a lobster scientist at the University of New Hampshire, clued him in. “He said, ‘Well, what you’re seeing, Brian, is actually a direct result of climate change.
