Algae bloom forces suspension of shellfishing in parts of Down East Maine

It’s the second straight year that a bloom of Pseudo-nitzschia, a phytoplankton that can carry toxic domoic acid, has forced a closure along large parts of the coast.

September 15, 2017 — A marine algae bloom that can carry a potentially deadly neurotoxin has forced the suspension of shellfish harvesting in parts of Down East Maine.

The state Department of Marine Resources reported Thursday that it was monitoring an active bloom of Pseudo-nitzschia, an ocean phytoplankton that carries domoic acid, a toxin that can cause sickness, memory loss and brain damage in humans. It’s the second year in a row that a toxic Pseudo-nitzschia bloom has halted harvesting of mussels, clams and oysters along large parts of the coast.

Before 2016, there was no record of a toxic bloom of this type in the Gulf of Maine.

The department’s public health section found levels of domoic acid that exceeded health standards in shellfish tested between Mount Desert Island and Gouldsboro. That area has been closed to harvesting and the department enacted a precautionary closure from Deer Isle to Machiasport, almost a third of Maine’s coastline.

Department spokesman Jeff Nichols said officials were monitoring the situation closely. There is no indication that contaminated shellfish have made their way to consumers, he said.

“It is impossible to determine at this point if the concentrations of domoic acid will increase in other areas,” Nichols said. “But we know that the phytoplankton that produces it grows rapidly, so we are carefully monitoring the entire coast and will be able to rapidly detect harmful levels of domoic acid and take action to protect the health of Maine’s shellfish consumers.”

Researchers find summer heat’s lasting longer in the Gulf of Maine

The warmer conditions endure two months longer than in the early 1980s, posing threats to the food chain and raising risks from more powerful hurricanes.

September 11, 2017 — New scientific research has revealed that summer temperatures in the Gulf of Maine, the second fastest warming part of the world’s oceans, are persisting two months longer than they were as recently as the early 1980s.

The findings, by a Maine-led team of scientists, have ramifications for marine life, fishermen and the strength of hurricanes, which appear in late summer and are fueled by warm water.

“What we found was quite astonishing in that almost all the warming is in the late summer and the winter is not contributing very much at all,” says the project’s lead scientist, University of Maine oceanographer Andrew Thomas. “You can think of impacts all across the food chain, from animals that have actual temperature tolerances to the distribution of species, their prey, and even their predators, not to mention the bacteria and viruses, which we have no idea how they will react.”

The researchers used daily satellite readings collected between 1982 and 2014 to map changes in sea surface temperatures along the Eastern Seaboard from North Carolina to Nova Scotia, breaking out the data by month to reveal seasonal differences in warming rates. They weren’t surprised to find the strongest warming in the Gulf of Maine and adjacent Scotia Shelf – team members had worked with Andrew Pershing of the Gulf of Maine Research Institute in Portland to demonstrate this in a 2015 study – but the profound seasonal differences were unexpected.

The satellite data show warming trends across the Gulf of Maine for every month and very sharp increases during July, August and September, especially off the Maine coast. While the Gulf of Maine warmed by an average of 0.72 degrees Fahrenheit per decade during the 33-year period, the warming rate was twice that in the months of July through September, or 1.44 degrees F per decade.

Shrimp plan changes advance

September 11, 2017 — ELLSWORTH, Maine — Meeting in Portland at the end of August, the Atlantic States Marine Fisheries Commission’s Northern Shrimp Section selected several final measures for inclusion in the latest revision to the Fishery Management Plan for northern shrimp.

Known as “Amendment 3,” the latest version of the plan will bring about a number of significant changes to the way the fishery is managed — if indeed the northern shrimp fishery is ever resuscitated. Because fisheries scientists believed that the northern shrimp population had collapsed, commercial shrimp fishing on the Gulf of Maine has been banned since 2014 with only an extremely limited harvest for scientific data collection purposes permitted.

Before the amendment becomes effective, it will have to be approved by the ASMFC. In its recent action, the shrimp section also recommended that the commission approve the amendment at its next meeting, tentatively scheduled to be held in Norfolk, Va., next month.

The newly recommended provisions would make several changes in both the philosophy and the practical measures affecting the management of the shrimp fishery.

The plan’s stated objectives will now call for managing the resource to support a viable fishery and will give individual states more control over the way the fishery is managed.

New Rules for New England Shrimp Fishery — if It Reopens

September 7, 2017 — PORTLAND, Maine (AP) — With the prospect of New England’s shuttered shrimp fishery reopening this winter, new rules are being designed to perpetuate the crustacean’s numbers and prevent another shutdown.

Maine fishermen once caught millions of pounds of the shrimp every year, with fishermen also bringing some ashore in New Hampshire and Massachusetts. But as the Gulf of Maine waters warmed, the catch plummeted from more than 13 million pounds in 2010 to less than 700,000 in 2013. The fishery shut down that year.

A decision on whether to allow the fishery to reopen could come in November.

With that in mind, an arm of the regulatory Atlantic States Marine Fisheries Commission is developing new rules for the fishery to put it in a better position to sustain itself if it does reopen, said Max Appelman, a fishery management plan coordinator for the Atlantic States.

Sturgeon ruling may impact federally funded projects

Merrimack River made ‘critical habitat’ for Atlantic sturgeon

September 1, 2017 — They are large, bony fish whose ancestors began swimming the Earth during the Triassic period, some 245 million years ago.

The federal government says the Atlantic sturgeon is now an endangered species in some places and is threatened in others, and that states up and down the Eastern Seaboard must take necessary measures to ensure their survival.

A ruling handed down on Aug. 16 by the Department of Commerce through the National Oceanic and Atmospheric Administration, designates the Gulf of Maine as a critical habitat for the fish, which includes approximately 152 miles of water in the Merrimack River in Massachusetts, the Penobscot, Kennebec, Androscoggin and Piscataqua rivers of Maine, and the Cocheco and Salmon Falls rivers of New Hampshire.

But what sort of impact will the efforts to replenish the Atlantic sturgeon population have on Merrimack Valley cities like Haverhill and Lawrence?

Allison Ferreira, spokeswoman for NOAA’s Greater Atlantic Regional Fisheries Office, said Friday that the ruling mandates that when a federal agency constructs or develops a project near the river or there is a project that is receiving some amount of federal money, such as a highway or bridge project where there could be significant water runoff, that agency must contact NOAA to ensure proper measures are taken so as not to upset the fish’s natural habitat.

American eel migration

August 30, 2017 — Eels are now descending out of the rivers all along the Gulf of Maine and every large prey fish in the ocean is waiting for them like kids looking for the ice cream truck. For the next few weeks fishermen will find that using eels for bait will be the key to landing those 50-inch stripers that are fueling up for their run south in October and November.

The American eel (Anguilla rostrata) is still a bit of a mystery among those that have spent a life time studying their life cycle. They are one of the few life forms that migrate from fresh water to the ocean to spawn in a process described as catadromous. They are also facultative which means they can live in a variety of environments such as fresh water rivers and lakes or salty oceans.

Although Aristotle thought they were created in the mud of streams and Pliny the Elder believed that they were formed from scales scraped off on rocks, it was not until 1922 that Danish biologist Johannes Schmidt discovered that eels spawned in the Sargasso Sea. He confirmed his discovery in a two year ocean voyage between 1928-30. What is one of the weird facts of science is that while we know they spawn in the Sargasso Sea because the eggs and young have been observed there, no adult eel has ever been found in the area.

Atlantic Herring Eastern Maine Spawning Closure in Effect Starting August 28, 2017 through September 24, 2017

August 23, 2017 — ARLINGTON, Va. — The following was released by the Atlantic States Marine Fisheries Commission:

The Atlantic herring Area 1A (inshore Gulf of Maine) fishery regulations include seasonal spawning closures for portions of state and federal waters in Eastern Maine, Western Maine and Massachusetts/New Hampshire. The Atlantic States Marine Fisheries Commission’s Atlantic Herring Section approved a forecasting method that relies upon at least three samples, each containing at least 25 female herring in gonadal states III-V, to trigger a spawning closure. However, if sufficient samples are not available then closures will begin on predetermined dates.

There is currently only one sample for the Eastern Maine spawning area to determine spawning condition; therefore, the Eastern Maine spawning area will be closed starting at 12:00 a.m. on August 28, 2017 extending through 11:59 p.m. on September 24, 2017. Vessels in the directed Atlantic herring fishery cannot take, land or possess Atlantic herring caught within the Eastern Maine spawning area during this time and must have all fishing gear stowed when transiting through the area. An incidental bycatch allowance of up to 2,000 pounds of Atlantic herring per trip/calendar day applies to vessels in non-directed fisheries that are fishing within the Eastern Maine spawning area.

Eastern Maine spawning area includes all waters bounded by the following coordinates:

Maine coast   68° 20’ W

43° 48’ N       68° 20’ W

44° 25’ N       67° 03’ W

North along the US/Canada border

Where’s the kelp? Warm ocean takes toll on undersea forests

August 22, 2017 — APPLEDORE ISLAND, Maine — When diving in the Gulf of Maine a few years back, Jennifer Dijkstra expected to be swimming through a flowing kelp forest that had long served as a nursery and food for juvenile fish and lobster.

But Dijkstra, a University of New Hampshire marine biologist, saw only a patchy seafloor before her. The sugar kelp had declined dramatically and been replaced by invasive, shrub-like seaweed that looked like a giant shag rug.

“I remember going to some dive sites and honestly being shocked at how few kelp blades we saw,” she said.

The Gulf of Maine, stretching from Cape Cod to Nova Scotia, is the latest in a growing list of global hotspots losing their kelp, including hundreds of miles in the Mediterranean Sea, off southern Japan and Australia, and parts of the California coast.

Among the world’s most diverse marine ecosystems, kelp forests are found on all continental coastlines except for Antarctica and provide critical food and shelter to myriad fish and other creatures. Kelp also is critical to coastal economies, providing billions of dollars in tourism and fishing.

The likely culprit for the loss of kelp, according to several scientific studies, is warming oceans from climate change, coupled with the arrival of invasive species. In Maine, the invaders are other seaweeds. In Australia, the Mediterranean and Japan, tropical fish are feasting on the kelp.

Maine fishermen, scientists combine forces with goal to save shrimp fishery

A new Fisheries Management Plan has been created for the fishery that has been closed since 2014.

August 21, 2017 — For more than 20 years, Dana Hammond made close to half his annual income shrimping. But his shrimping profits began to dwindle in 2013. That season, regulators were alarmed by the lack of shrimp biomass in the Gulf of Maine, and the amount he was allowed to catch was cut 72 percent. The fishery was closed entirely in 2014. It hasn’t reopened since and Hammond, who fishes out of Portland on his boat the Nicole Leigh, has been trying to make up the deficit from his other main source of income, groundfishing.

But Hammond isn’t ready to let shrimping go. It’s an ideal winter fishery for him, allowing him to stay close to shore during rough and cold weather. He’s so vested in the future of the fishery that this summer he went to sea with the Northeast Fisheries scientists who conduct the annual summer survey, the main source of data that determines the status of the fishery every year.

“I didn’t get paid,” Hammond said. “I went anyway because I want to make sure they are doing stuff right.”

Hammond’s goal is to help the scientists be better fishermen – the more they catch, the more likely it is his fishery will reopen. Or better put, the more shrimp the survey finds, the better chance it is that there will be another season for Maine shrimpers. The survey concluded earlier in August and though its findings won’t be available until late October, it is the key to determining whether Atlantic States Marine Fisheries Commission will decide at its meeting in early to mid-December whether to reopen the fishery for the tiny Northern shrimp (Pandalus borealis) in 2018.

In the event that the fishery does reopen, it will likely follow different rules. The Atlantic States Marine Fisheries Commission has, with the cooperation and input of local fishermen, developed a new Fisheries Management Plan, updated in consideration of the recent problems in the shrimp fishery. That plan, known as Amendment 3 will be finalized at a meeting in Portland on Aug. 31.

Typically, putting the regulatory side of a fishery in contact with those who do the fishing entails some tension, distrust even, the kind that can make for a combative relationship. The people who make their living on the water don’t want to be told what to do and how to do it, especially not by people who came up in the world of petri dishes and test tubes, not traps and trawls.

But as the Northern shrimp fishery faces the most extreme challenge in a history that spans nearly a century, the relationship between shrimpers and scientists has become, cautiously, more collaborative. The more so the better, from the perspective of fisheries biologist Peter Chase, who oversees the annual survey for the National Oceanic and Atmosphere Administration’s (NOAA) Northeast Fisheries Science Center. He’s used to getting a lot of questions about the survey as soon as he comes ashore in summer – starting with, “did you see a lot of shrimp?” Moreover, he understands the frustrations of the fishermen. Some of them “have been vocal about complaining about our survey,” he said. “Others have been really helpful.” Like Hammond.

“It shouldn’t be an us-versus-them thing here,” Chase said. “I don’t want to put anyone out of business.”

“We want to be in this together,” he added. “This is research that I am hoping will show that the resource is coming back.”

NOAA Fisheries Designates Critical Habitat for Atlantic Sturgeon

August 16, 2017 — The following was released by NOAA Fisheries:

NOAA Fisheries today designated critical habitat for Atlantic sturgeon–an important step to ensuring their recovery.

The critical habitat designation will require federal agencies to consult NOAA Fisheries if they operate or fund activities that may affect designated critical habitat in more than 3,968 miles of important coastal river habitat from Maine to Florida. Atlantic sturgeon was listed under the Endangered Species Act in 2012 and is comprised of the threatened Gulf of Maine distinct population segment and the endangered New York Bight, Chesapeake Bay, Carolina, and South Atlantic distinct population segments.

The ESA requires that NOAA Fisheries designate critical habitat when a species is listed as threatened or endangered. Under the ESA, critical habitat is defined as specific areas within the geographical areas that are occupied by the species, that contain physical or biological features essential to the conservation of that species, and that may require special management considerations.

The designation of critical habitat does not include any new restrictions or management measures for recreational or commercial fishing operations, nor does it create any preserves or refuges. Instead, when a federal agency funds, authorizes, or carries out activities that may affect critical habitat, it must work with NOAA Fisheries to avoid or minimize potential impacts to critical habitat. The activity of the federal agency may need to be modified to avoid destroying or adversely modifying the critical habitat.

“We look forward to working with our federal partners to reduce potential impacts to Atlantic sturgeon critical habitat,” said Samuel D. Rauch III, deputy assistant administrator for regulatory programs at NOAA Fisheries. “Our focus now will be on providing guidance to federal agencies to help them carry out their actions efficiently and effectively while minimizing impacts to habitat that is critical to these endangered and threatened populations of sturgeon.”

Atlantic sturgeon are anadromous and use coastal and estuarine waters throughout their lives, and travel to rivers to spawn or lay their eggs. Unlike some anadromous fish, sturgeon do not die after spawning and will return to spawn multiple times. They can grow up to 14 feet long, weigh up to 800 pounds, and live up to 60 years.

Historically, Atlantic sturgeon inhabited approximately 38 rivers in the United States spanning from Maine to Florida. Scientists identified 35 of those as spawning rivers. Atlantic sturgeon can now be found in approximately 32 of these rivers, and spawn in at least 20 of them. Critical habitat areas in coastal rivers were identified based on physical and biological features, such as soil type in the river bed, water temperature and salinity, and underwater vegetation, that are essential to the conservation of Atlantic sturgeon, particularly for spawning and development.

Atlantic sturgeon were harvested heavily in the twentieth century, particularly for their eggs (or roe) used for caviar. Overfishing led to a decline in abundance of Atlantic sturgeon, and in 1998 the Atlantic States Marine Fisheries Commission issued a coast-wide moratorium on the harvest of Atlantic sturgeon, and NOAA Fisheries followed with a similar moratorium in federal waters.

More information on the critical habitat designation is available in the Federal Register notice and on our website.
