As Lobsters Decline, Fishermen Switch to Jonah Crab

November 15, 2018 — The lobster industry in southern New England has been on the decline for decades. As waters warm, some lobster fishermen are adapting by switching their catch to Jonah crab, a crustacean once considered a trash species.

Mike Palombo is captain of a 72-foot lobster boat, but his main catch is crabs.

He leaves from the Sandwich Marina for three-day fishing trips, going out over 100 miles to haul traps in the Canyons. One day this fall, he and his crew returned with around 23,000 Jonah crab and 2,000 lobsters in big saltwater holding tanks. “It was a good trip, very productive,” he said.

Jonah crab are sturdy, hard-shelled creatures, with black-tipped claws. They’re about a pound apiece. You might not have heard of them, but Jonah crab are sustaining Southern New England fishermen left stranded by the decline of lobsters.

Tracy Pugh, a lobster biologist with the Massachusetts Division of Marine Fisheries, said there’s been a drop in the lobster population south of the Cape, in part because the water temperature is rising. “The Southern New England lobsters are experiencing the bad aspects of climate change,” she said, “because they’re already in the southern extent of their range.”

Pugh says the warmer water is causing the lobsters to experience physiological stress. It’s also bringing in new diseases that affect lobster, and an uptick in predators like black seabass and tautog.

New protections for herring but lobster bait crunch imminent

November 12, 2018 — Fishing managers are considering extending new protections to Atlantic herring, but catch quotas for the important bait fish are still likely to plummet before the end of the year, which is bad news for the American lobster industry.

Herring is the most important bait source for the lobster fishery, which is one of the most lucrative marine industries in New England. A recent scientific assessment of the herring population says the fish’s population has fallen in the past five years.

An arm of the Atlantic States Marine Fisheries Commission voted last month to initiate changes to try to better protect spawning herring off of New England.

The new protections are coming at a time when the lobster and herring fisheries are expecting a dramatic cutback in herring quota. The National Oceanic and Atmospheric Administration is expected to propose new rules about herring fishing this month and implement them by early 2019, when next year’s herring fishing season starts.

Even Lobsters Can’t Escape Trump’s Trade War

November 7, 2018 — In his cargo shorts and T-shirt, Mark Barlow looked anything but an international trade warrior. Yet a few weeks ago, when he slid open the door to his low-slung warehouse in a scrappy industrial lot to reveal concrete tanks filled with 375,000 gallons of 40-degree water and a fortune in live Maine lobsters, he might as well have been leading a battlefield tour.

Since the 1990s, Barlow has built his company, Island Seafood, into a $50 million-a-year business by shipping live lobsters around the world. He exported one out of every five to China until recently. A lobster plucked from a trap in Maine’s frigid waters—home to North America’s richest fishery—could surface on a dinner plate in Beijing two days later. The first months of 2018 were the best start in Island Seafood’s history, says Barlow, who this year expected to ship a million pounds of lobster to Shanghai, Guangzhou, and other Chinese cities, where he’s built relationships for a decade. Then, as Barlow, a 57-year-old bear of a man who speaks like someone who’s spent years negotiating on the docks, puts it: “The orangutan in Washington woke up from a nap and decided to put tariffs on China,” and “the Chinese stopped buying immediately.”

If you want to understand the modern global economy, the implications of climate change, and the unintended consequences of President Trump’s trade wars, then you ought to “consider the lobster.” The writer David Foster Wallace’s 2004 essay of that name riffed on the history (“Up until sometime in the 1800s … lobster was literally low-class food, eaten only by the poor and institutionalized”) and morality (“It’s not just that lobsters get boiled alive, it’s that you do it yourself”) of our love affair with Homarus americanus. To consider the lobster now, almost 15 years later, is to study crustacean economics just as U.S.-China trade tensions reach a roiling boil.

As Trump has rewritten America’s economic relationships, some of the country’s most prized exports—Kentucky bourbon, Harley-Davidson motorcycles, Midwestern soybeans—have become retaliatory targets for China and the European Union. For its part, Beijing began imposing a 25 percent tariff on a long list of imports from the U.S., including live lobsters, on July 6. “The second this happened, I said to my sales team, ‘China’s dead,’ ” Barlow says. Correspondence with his Chinese customers confirmed his hunch. “I don’t think there is [a] way to import U.S. lobster,” one buyer texted.

MASSACHUSETTS: Losing lobster lines

November 6, 2018 — Scientists from the New England Aquarium will spend much of next year testing ropeless lobster gear as part of the escalating effort to mitigate entanglements with right whales and other marine species.

The research project, funded with a $226,616 grant recently received from the National Oceanic and Atmospheric Administration, will involve co-operative research with active lobstermen, possibly including some from the state’s most lucrative lobster port in Gloucester, according to one of the aquarium’s chief scientists.

“We want to get good technology in the hands of fishermen so they can evaluate its potential,” said Tim Werner, the aquarium’s senior scientist and director of its Consortium for Wildlife Bycatch Reduction. “They need to be able to use it and find out what it needs to be functional.”

Werner said researchers already have begun to develop various types of ropeless traps, using different technologies to achieve the same goal of drastically reducing or eliminating entanglements of leatherback sea turtles and whales in the forest of vertical lines stretching from fishing gear on the ocean floor to the ocean’s surface.

Researchers identify causes of decline in shellfish harvests

November 5, 2018 — NOAA researchers studying the 85 percent decline between 1980 and 2010 of the four most commercially-important bivalve mollusks — eastern oysters, northern quahogs, softshell clams, and northern bay scallops — have identified the causes.

Along with the sharp decline in commercially important bivalves, there has been a corresponding decline in the numbers of fishermen (89 percent) who harvested the bivalves, said researchers with NOAA’s National Marine Fisheries Service.

The bivalve declines are in contrast to the previous three decades (1950–80) when the combined landings of the same bivalves were much higher and the trend in each of their annual landings was nearly level, decade by decade.

The only exceptions to the declines were seen in the harvest of northern quahogs in Connecticut and American lobsters in Maine. However, the numbers of American lobster landings have fallen precipitously – as much as 98 percent – from southern Massachusetts to New Jersey.

The researchers also found during the course of the study that a number of groups of marine and land animals have also experienced large shifts in abundance since the early 1980’s.

NOAA Says Environmental Factors Dropped East Coast Bay Shellfish Landings by 85% Since 1980

November 1, 2018 — SEAFOOD NEWS — Want a scary headline for halloween? How about this: NOAA claims East Coast shellfish (oysters, quahogs, softshell clams, and bay scallops) landings have declined 85% since 1980, due to environmental factors.

Researchers from the Northeast Fisheries Science Center studying the sharp decline between 1980 and 2010 in documented landings of the four most commercially-important bivalve mollusks have identified the causes.

They say warming ocean temperatures associated with a positive shift in the North Atlantic Oscillation (NAO), which led to habitat degradation including increased predation, are the key reasons for the decline of these four species in estuaries and bays from Maine to North Carolina.

The NAO is an irregular fluctuation of atmospheric pressure over the North Atlantic Ocean that impacts both weather and climate, especially in the winter and early spring in eastern North America and Europe. Shifts in the NAO affect the timing of species’ reproduction, growth and availability of phytoplankton for food, and predator-prey relationships, all of which contribute to species abundance.

“In the past, declines in bivalve mollusks have often been attributed to overfishing,” said Clyde Mackenzie, a shellfish researcher at NOAA Fisheries’ James J. Howard Marine Sciences Laboratory in Sandy Hook, NJ and lead author of the study. “We tried to understand the true causes of the decline, and after a lot of research and interviews with shellfishermen, shellfish constables, and others, we suggest that habitat degradation from a variety of environmental factors, not overfishing, is the primary reason.”

Mackenzie and co-author Mitchell Tarnowski, a shellfish biologist with the Maryland Department of Natural Resources, provide details on the declines of these four species. They also note the related decline by an average of 89 percent in the numbers of shellfishermen who harvested the mollusks. The landings declines between 1980 and 2010 are in contrast to much higher and consistent shellfish landings between 1950 and 1980.

Exceptions to these declines have been a sharp increase in the landings of northern quahogs in Connecticut and American lobsters in Maine. Landings of American lobsters from southern Massachusetts to New Jersey, however, have fallen sharply as water temperatures in those areas have risen. Sea scallops also have remained in a stable stock cycle.

“A major change to the bivalve habitats occurred when the North Atlantic Oscillation (NAO) index switched from negative during about 1950 to 1980, when winter temperatures were relatively cool, to positive, resulting in warmer winter temperatures from about 1982 until about 2003,” Mackenzie said. “We suggest that this climate shift affected the bivalves and their associated biota enough to cause the declines.”

Research from extensive habitat studies in Narragansett Bay, RI and in the Netherlands, where environments including salinities are very similar to the northeastern U.S, show that body weights of the bivalves, their nutrition, timing of spawning, and mortalities from predation were sufficient to force the decline. Other factors likely affecting the decline were poor water quality, loss of eelgrass in some locations for larvae to attach to and grow, and not enough food available for adult shellfish and their larvae.

“In the northeast U.S., annual recruitments of juvenile bivalves can vary by two or three orders of magnitude,” said Mackenzie, who has been studying bay scallop beds on Martha’s Vineyard with local shellfish constables and fishermen monthly during warm seasons for several years. In late spring-early summer of 2018, a cool spell combined with extremely cloudy weather may have interrupted scallop spawning, leading to what looks like poor recruitment this year. Last year, Nantucket and Martha’s Vineyard had very good harvests due to large recruitments in 2016.

“The rates of survival and growth to eventual market size for shellfish vary as much as the weather and climate,” Mackenzie said.

Weak consumer demand for shellfish, particularly oysters, in the 1980s and early 1990s has shifted to fairly strong demand as strict guidelines were put in place by the Interstate Shellfish Sanitation Conference in the late 1990s regarding safe shellfish handling, processing and testing for bacteria and other pathogens. Enforcement by state health officials has been strict. The development of oyster aquaculture and increased marketing of branded oysters in raw bars and restaurants has led to a large rise in oyster consumption in recent years.

Since the late 2000s, the NAO index has generally been fairly neutral, neither very positive nor negative. As a consequence, landings of all four shellfish species have been increasing in some locations. Poor weather for bay scallop recruitment in both 2017 and 2018, however, will likely mean a downturn in landings during the next two seasons.

Canada looking to add flexibility to right whale protection measures

October 30, 2018 — Canadian authorities are seeking to add greater flexibility to fishing regulations put in place to protect critically endangered North American right whales.

At an industry roundtable in Dartmouth, Nova Scotia, on Tuesday, 23 October, Minister of Fisheries, Oceans and the Coast Guard (DFO) Jonathan Wilkinson signaled a willingness to lessen the severe restrictions placed on various fisheries in 2018 to protect the whales.

In 2017, the death of 12 right whales in Canadian waters prompted DFO to impose extreme measures on fishing, shipping, and maritime traffic for the 2018 season. No right whales died in Canadian waters during this period, and the stiff measures kept Canada’s fishery on the right side of U.S. marine mammal protection legislation, which helped maintain access to U.S. markets for Canadian suppliers. However, fishermen said the closures cost them millions of dollars.

In recent months, regulators, scientists, and fishermen have worked together to find an accommodation in procedures for protecting the right whales. As a result of this work, a new pilot project has been proposed for the Grand Manan lobster fishery. In 2018, the sighting of a single right whale caused a 15-day shutdown of the fishery. For 2019, it will be sufficient for the Grand Manan lobster fishermen to cut their trailing buoy when a right whale is spotted.

New Brunswick Crab fishermen, who work in the Gulf of St. Lawrence, are hoping this potential new flexibility extends to them. Martin Noel of New Brunswick’s Acadian Crab Fishermen’s Association said his group supported that avenue.

NGOs condemn EU Parliament’s decision to ‘overfish Atlantic waters’

October 29, 2018 — The European Parliament has voted to approve the multiannual plan for management of north-east Atlantic waters, despite the plan’s allowance for unsustainable fishing, said Oceana, ClientEarth and Seas at Risk.

The Western Waters, an area that stretches from Portugal to France, Ireland and the UK, is a heavily-used fishery for cod, haddock, plaice, sole and Norway lobster. In 2017, the area yielded 368,000 metric tons of produce, with a combined first sale value of roughly €1.4 billion.

However, current estimates suggest that as much as 41% of the region’s stocks are overfished. Environmental NGOs have been putting pressure on the EU Parliament to reduce catch quotas in the region as part of the 2013 commitment in the common fisheries policy (CFP) to end overfishing in European waters by 2020 at the latest.

The latest vote has agreed to allow fishing at levels above the scientifically-advised maximum sustainable yield, a move that many NGOs have condemned as being adverse to the objectives laid out in the CFP.

“The Parliament has agreed fishing mortality ranges that, at their upper limit, can exceed the fishing rates above scientifically advised sustainable levels,” said Andrea Ripol, fisheries policy offer at Seas At Risk. “This means that stocks will not be restored to healthy levels, bringing negative socioeconomic impacts in the longer term.”

Turning an invasive problem into a bait solution

October 25, 2018 — With concerns growing over a likely bait shortage in the lobster industry in Maine and Canada due to a drastic cut in the upcoming season’s herring quota, Nova Scotia resident Patrick Swim has a possible solution. Swim thinks he can solve the bait shortage by harvesting an invasive species.

Silver carp is one of the four species of the invasive Asian carp (silver, bighead, grass, and black) that have placed the Great Lakes water system at risk. Carp were brought to North America in the 1970s as a biological control of algae, plants, and snails in aquaculture sites. Subsequent flooding allowed them to escape their pens, which created a new problem for the environment and marine life. A mature meter-long carp can weight 40 kilograms and consume up to 40 percent of their body weight each day, which puts stress on resources for native species. They also reproduce rapidly.

Swim was intrigued by reports that silver carp are so disturbed by noise and vibration caused by boat motors that they jump up to three meters out of the water. While looking at this flying fish phenomenon, Swim, whose family have long fished lobster on Canada’s Cape Sable Island, had an idea to harvest the carp, freeze it, cut it into pieces and sell it as a cheap bait to East Coast lobster fishermen.

In the past decades, Asian carp have replaced native fish species in areas of the Mississippi River and its tributaries. Their advance towards the Great Lakes has spurred the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, U.S. Coast Guard, U.S. Environmental Protection Agency, and the Illinois Environmental Protection Agency to spend tens of millions of dollars annually trying to contain them. So far, electro-magnetic fields and fish fences have prevented all but a few carp from entering the lakes.
