Gulf of Maine lobster population past its peak, study says, and a big drop is due

January 23, 2018 — The Gulf of Maine lobster population will shrink 40 to 62 percent over the next 30 years because of rising ocean temperatures, according to a study published Monday.

As the water temperature rises – the northwest Atlantic ocean is warming at three times the global average rate – the number of lobster eggs that survive their first year of life will decrease, and the number of small-bodied lobster predators that eat those that remain will increase. Those effects will cause the lobster population to fall through 2050, according to a study by researchers at the Gulf of Maine Research Institute, the University of Maine and the National Ocean and Atmospheric Administration.

Looking ahead 30 years, the researchers predict a lobster population “rewind” to the harvests documented in the early 2000s. In 2002, 6,800 license holders landed 63 million pounds of lobster valued at $210.9 million. By comparison, 5,660 license holders harvested 131 million pounds valued at $533.1 million in 2016.

“In our model, the Gulf of Maine started to cross over the optimal water temperature for lobster sometime in 2010, and the lobster population peaked three or four years ago,” said Andrew Pershing, GMRI’s chief scientific officer and one of the authors of the study. “We’ve seen this huge increase in landings, a huge economic boom, but we are coming off of that peak now, returning to a more traditional fishery.”

Industry leaders have been girding themselves for a decline in landings ever since the recent boom began. While not everybody believes the decline will happen that fast or fall so much, most lobstermen admit the impact that warming water has had on their fishery, said Dave Cousens, the president of the Maine Lobstermen’s Association. It drove up landings by pushing lobsters into the Gulf of Maine, and over time it will drive lobsters out to colder offshore waters or the Canadian Maritimes, he said.

Conservation groups sue to force greater protection for North Atlantic right whale

January 19, 2018 — Three national organizations went to court Thursday in an effort to force the federal government to provide greater protections for the endangered North Atlantic right whale.

The plaintiffs allege that the federal government has failed to manage the fishing industry by not enforcing the Endangered Species Act and the Marine Mammal Protection Act. Scientists say right whales are facing extinction largely because the animals die after becoming entangled in lobster trap lines and commercial fishing gear.

The civil suit against the National Marine Fisheries Service and the U.S. Secretary of Commerce was filed Thursday in federal court in Washington, D.C., by the Center for Biological Diversity, Defenders of Wildlife, and the Humane Society of the United States.

During a meeting in Halifax, Nova Scotia, in October, scientists said the species is doomed to extinction by 2040 if humans don’t make substantive changes to protect them. A total of 17 right whales were found dead last summer and fall in the waters of the Gulf of St. Lawrence and off Cape Cod.

Dave Cousens, president of the Maine Lobsterman’s Association and a lobsterman who fishes out of South Thomaston, said he wasn’t surprised by the lawsuit after last year’s die-off.

“A lot of whales died,” Cousens said. “We have done a lot (to avoid entanglements) in Maine, and I have to say I don’t think Maine has been the cause of any of the deaths.”

Cousens said he fully expected that conservation organizations would demand that additional steps be taken to avoid entanglements with fishing gear.

In the suit, plaintiffs sharply criticize the NMFS for supporting a 2014 biological opinion that found commercial fisheries are likely to kill or seriously injure more than three North Atlantic right whales a year, but also led the federal agency to conclude “that the fishery is not likely to jeopardize the continued existence of North Atlantic right whales.”

Maine fishermen see warning signs in lobster surge

March 23, 2017 — After Maine’s lobster industry set sales records for a second straight year, area fishermen are enjoying the boom while the water is warm.

Literally.

Rising sea temperatures are benefiting Maine’s iconic crustacean, leading to an increase in population while other marine species, such as soft-shell crabs, have suffered a decline, according to fishermen who spoke at a March 16 Maine Coast Fishermen’s Association panel.

But the factors for today’s success may portend tomorrow’s economic and cultural disaster, according to some area fishermen.

“We’re going to start going down when it gets warmer,” Maine Lobstermen’s Association President Dave Cousens told the audience at the Frontier Cafe.

Cousens was joined by MCFA President Gerry Cushing, of Port Clyde; Chebeague Island fisherman Alex Todd, and lobsterman Steve Train of Long Island.

Between July and October 2016, Cousens said, the ocean temperature was 60 degrees where he fishes in South Thomaston – a rise of three degrees since he began hauling traps three decades ago.

If temperatures rise three more degrees, he said, “lobster larvae will not survive. That’s what we’re facing.”

Last year, Maine fishermen hauled a record $130 million pounds of lobster, and the industry saw its value rocket $30 million, according to the Department of Marine Resources.

But the panelists warned the boom will be temporary.

“You don’t have to look too far south to see what’s coming,” Cousens said, noting the sharp demise of lobster populations off Cape Cod, Massachusetts, and Long Island, New York.

“That line’s just moving north,” Scott Moody, owner of Moody’s Seafood in Cundy’s Harbor, agreed the next day over the phone.

Moody, a fourth-generation lobsterman, fished in Harpswell for 30 years before starting his wholesale business, which includes five retail locations along Maine’s coast.

He buys directly from lobstermen and shellfish harvesters, and sells their product mostly to a distributor in Boston.

“In shellfish, we’ve seen a big turn,” Moody said last week. “I used to buy about $1 million in soft-shell (clams) in the Harpswell location,” at 337 Cundy’s Harbor Road.

“Since the climate change, I’m doing ($750,000) in hard-shell and only $250,000 in soft-shell,” he said.

Years ago, waiting to unload at his Boston distributor, “I’d be sitting behind five or six trucks of soft-shell clams,” he recalled. “They started to disappear. Then I’ve see guys bringing in hard-shell.”

He explained how warming waters increased the number of predators, such as Japanese green crabs, that can smash a clam’s soft shell.
