MAINE: Winter 2017 shrimp cooperative sampling program

December 5th, 2016 — The following was released by the Maine Department of Maine Resources: 

The Atlantic States Marine Fisheries Commission (ASMFC) and the DMR are seeking eight shrimp trawling vessels and captains to collect northern shrimp samples in three regions of the Maine coast (three vessels in Western ME, three in Mid-coast ME, and two in Eastern ME), beginning in mid- to late January, 2017, fishing once a week for eight weeks until mid- to late March.  Each participant will be required to collect samples each week in one region, and will be allowed to land and sell up to 1,200 pounds of northern shrimp per trip.  There will be no further compensation.  Selection preference will be given to applicants using a size-sorting grate (designed to release small shrimp).  Highest selection preference will go to applicants who will participate in a compound grate study.

In addition, we are seeking five shrimp trapping vessels and captains to collect northern shrimp samples in two regions of the Maine coast (four vessels in Mid-coast ME, and one in Eastern ME), beginning January 30, 2017, once a week, for eight weeks until March 26.  Each trapper will be allowed to fish up to 40 traps each, hauled as often as necessary during the project.  Participants will be allowed to land and sell up to 500 pounds of shrimp per week.  There will be no further compensation.  

The purpose of the project is to collect northern shrimp samples during the winter period when the shrimp are in inshore waters, to collect data on the timing of the egg hatch, and the size, gender, and developmental stage of the shrimp.  We also hope to collect data on the performance of the compound size-sorting grate.

Please see the attached announcement for details on the project, how to apply, the application deadline (Dec. 19, 2016), and the selection process.  Please contact me if you have trouble opening the attachments.  This information is also available on our web site at http://www.maine.gov/dmr/science-research/species/shrimp/winter2017.html .

Mercury Levels in Gulf of Maine Tuna on the Decline

December 5th, 2016 — There’s some good news for sushi lovers. A new report finds that over an 8-year period, mercury levels in Gulf of Maine tuna declined 2 percent a year — a decline that parallels reductions in mercury pollution from Midwest coal-fired power plants.

Two years ago, Dr. Nicholas Fisher, a professor of marine sciences at Stony Brook University in New York, had a bit of luck — he found out that a colleague had established a collection of 1,300 western Atlantic bluefin taken from the Gulf of Maine between 2004 and 2012.

“They were frozen, wasn’t the entire fish, just about a pound from each fish or so. And then my colleagues and I in New York dissected out muscle tissue from each sample and analyzed it to determine the mercury content of each fish,” he says.

And as they created a timeline for mercury content for each year, taking into account the age and size of each fish sampled, a clear picture emerged.

“There was a fairly steady decline for all ages of fish, and the decline rate was approximately 2 percent per year, which doesn’t sound all that dramatic, but over 10 years it’s about 20 percent. Over two decades its about 40 percent,” Fisher says.

Maine Outdoor Heritage Fund Grant Strengthens Public Health Protection, Opportunity for Shellfish Industry

December 2, 2016 — The following was released by the Maine Department of Marine Resources:

A $32,000 grant from the Maine Outdoor Heritage Fund has strengthened Maine Department of Marine Resources’ ability to protect public health and preserve opportunity for Maine’s shellfish industry.

The funds will allow the department to purchase equipment to test for domoic acid, a naturally-occurring biotoxin that can cause serious health risks including amnesic shellfish poisoning (ASP). The equipment will be purchased and DMR staff trained during the upcoming winter months.

While phytoplankton species that cause domoic acid have been detected in Maine waters for years, 2016 was the first year the biotoxin was found in concentrations that could cause adverse health impacts.

Levels of domoic acid detected by DMR’s biotoxin monitoring program in September triggered closures of shellfish harvesting areas between Bar Harbor and the Canadian Border. The event lasted until mid-November when the final closed area was re-opened.

The process of testing for domoic acid involves routine phytoplankton sampling at established sites along the Maine coast throughout the year. The samples are analyzed under a microscope by DMR staff and trained volunteers. If cell counts of the phytoplankton, known as Pseudo-nitzschia, in the water samples reach established levels, a test known as the Scotia Rapid test is conducted to determine if domoic acid is present.

If test results are positive, shellfish sampling in the vicinity begins and shellfish samples are sent to Bigelow Laboratory for Ocean Sciences for further confirmation using a method known as high-pressure liquid chromatography (HPLC).

If the concentration of biotoxin in the samples reaches a level established by FDA as a baseline for regulatory action, 20 parts per million in the case of domoic acid, the area associated with the toxic shellfish is immediately closed.

“Our partnership with Bigelow Laboratory for Ocean Sciences continues to be invaluable,” said Maine DMR Public Health Bureau Director Kohl Kanwit. “We began working with Bigelow Bigelow Laboratory in 2014 to implement HPLC testing for red tide. As a result Maine was the first state in the nation to transition from using mice to test for biotoxins to the more precise HPLC method, which uses chemical analysis instead of live animals,” said Kanwit.

“By transitioning the biotoxin monitoring program to HPLC, DMR is able to respond more effectively to emerging biotoxin threats such as ASP.”

Before HPLC testing was available, the department had no way to test for domoic acid. Instead, notification of possible ASP contamination came to the department from health officials dealing with a potential ASP illness. FDA then tested samples, which could take up to ten days, during which large sections of the Maine coast were closed until results were returned.

In 2012, approximately 50,000 acres of shellfish harvest area on the Maine coast were closed as a precaution for nine days while FDA results were pending. Test results ultimately indicated there were no levels of concern and the areas were reopened.

“HPLC testing by Bigelow Lab was a major improvement for us and for industry,” said Bryant Lewis, the DMR Biologist who wrote the grant and will oversee the project. “The new equipment, which will be housed at the DMR lab in Boothbay Harbor, will further strengthen our ability to deal with this emerging biotoxin.”

Shellfish samples collected as part of the department’s routine biotoxin monitoring program will still go to Bigelow Laboratory for analysis of paralytic shellfish poisoning and diarrhetic shellfish poisoning.

However, samples from areas that are shown by DMR testing to have high Pseudo-nitzschia cell counts and to be positive for domoic acid can be tested immediately with the new DMR equipment. This eliminates the potential need for precautionary closures while waiting for test results from the lab.

“Our partnership with the Bigelow Laboratory enabled us to effectively monitor and manage the ASP event this summer and we will continue to partner with them for routine monitoring,” said Lewis. “This new equipment will improve Maine’s capacity to make rapid, scientifically sound management decisions that protect the health of Maine shellfish consumers while preserving opportunity for Maine’s shellfish industry.”

Coast Guard escorts four to safety after heavy winds, seas damage fishing boat off Portland, Maine

December 2nd, 2016 — The Coast Guard assisted four people to safety Wednesday after heavy winds and seas damaged a fishing boat about 40 miles southeast of Portland, Maine.

A fisherman aboard the Gracelyn Jane sent a distress hail to Coast Guard Sector Northern New England watchstanders Tuesday evening and reported their fishing boat was disabled with four people aboard. The man reported the crew lost their GPS, the boat was losing power, and their windows had shattered.

On scene weather at the time was 30 knot winds and 10-14 foot seas.

The 270-foot Coast Guard Cutter Northland, homported in Portsmouth, Virginia, was approximately ten miles from Gracelyn Jane’s location and quickly diverted from their patrol to help. A helicopter crew from Coast Guard Air Station Cape Cod also deployed to provide assistance.

After arriving on scene, Northland’s crew found the Gracelyn Jane regained power and made way toward shore escorted by the Coast Guard.

Once closer to shore, a response boat crew from Coast Guard Station Boothbay Harbor relieved Northland’s crew from their escort and accompanied Gracelyn Jane into Boothbay Harbor, Maine.

MAINE: Scallop diving season about to start off of Maine coast

December 1, 2016 — PORTLAND, Maine — The season is about to begin for hearty souls who dive for scallops off Maine’s coast.

The diver season begins Thursday. The season for scallop fishermen who harvest their quarry using dragger boats gets underway on Monday.

Most of the state’s scallop catch is harvested by draggers, but dozens of divers also plunge into frigid waters to find the shellfish.

Maine’s scallop harvest has been growing in value along with the climbing value of scallops nationwide. Maine’s scallops were worth $12.70 per pound at the dock last year, which is the most in the state’s history. Price to consumers has also gone up.

The volume of the state’s harvest has been relatively steady, with divers and draggers bringing ashore more than 450,000 pounds of scallop meat for three straight years.

MAINE: Eel farmer wants to keep Maine’s wriggly gold close to home

December 1, 2016 — SOUTH PORTLAND, Maine — Sara Rademaker wants to give the East Coast’s most valuable eels a much shorter commute from river to sushi roll.

Baby eels, also called elvers, are at the center of a lucrative business in Maine, which is home to the only large-scale fishing operation for them in the country. Fishermen sold them for more than $2,000 per pound last year, and they typically are sent as seed stock to Asian aquaculture companies so they can be raised to maturity and processed into sushi and other food products.

But Rademaker, a Maine aquaculture farmer, is looking to change all that and keep more of the state’s valuable baby eels closer to home. She’s operating a small eel farming operation in South Bristol, Maine, that raises the elvers so they can be sold live and fully grown to local restaurants.

Rademaker launched American Unagi in 2014 and sold her first eels to Maine sushi restaurants this summer. She is hoping to scale up production in the coming years.

“The local food movement is shifting toward seafood,” she said. “Having products that are produced local, that have traceability, that can show they are sustainable is going to be important.”

Eel aquaculture in America is underdeveloped, as most of the business takes place in Asia and Europe. Rademaker buys her elvers locally from purchasers who acquire them from Maine fishermen, and she is raising her eels at the University of Maine’s Darling Marine Center. She said she expects to sell more than 2,000 pounds of the eels within two years.

Maine is one of only two states with an elver fishery; South Carolina’s fishery is much smaller.

Rademaker has set an ambitious goal. America’s entire wild-caught eel fishery, which is mostly centered around Maryland, only yields between 800,000 and a million pounds of eels per year. Wild-caught older eels, which make up most of the fishery, are worth much less than the baby eels Maine fishermen take from rivers and streams.

Idea to cut NASA’s role in climate science could be major loss for Maine, scientists say

November 29, 2016 — Maine scientists are decrying the assertion by a senior adviser to President-elect Donald Trump that the new administration will eliminate or dramatically scale back NASA’s climate research.

The scientists say the elimination of the agency’s earth science programs would be catastrophic for climate science research in Maine, impairing their ability to detect and analyze effects on fisheries, forests and agriculture. Maine is a hub of climate research – especially as it relates to the oceans – and the work relies on data collected by NASA satellites and processed by the agency’s experts.

“If we lose these data sets and capabilities, that will be a major loss to us being able to monitor and track changes here in Maine and in other areas that impact us,” said Andrew Thomas, a professor of oceanography at the University of Maine’s School of Marine Sciences, which receives more than one-sixth of its research funds from NASA. “Basically, you’re chopping off one of your arms and saying, ‘Carry on.’ ” The school’s Satellite Data Lab is using NASA data to analyze effects of melting ice in the Gulf of Alaska and to monitor marine algae production in the California Current.

Bob Walker, a former Pennsylvania congressman who serves as Trump’s space policy adviser, said in interviews last week that the administration would realign NASA’s budget, prioritizing exploration of “deep space” over space-based observations of Earth, which he has previously characterized as “politically correct environmental monitoring.” Earth observations would instead be made by the National Science Foundation or National Oceanic and Atmospheric Administration, two much smaller agencies with little experience or expertise in space-based climate monitoring.

MAINE: Scallop season opens with high hopes

November 29, 2016 — ELLSWORTH, Maine — After an eight-month hiatus when, like summer tourists, the only scallops in local stores are “from away,” the Maine scallop fishing season is finally opening, at least for a handful of harvesters.

All along the coastline, licensed scallop divers are allowed to start fishing for the succulent bivalves today, Thursday, Dec. 1. Dragger fishermen will have to wait to wet their gear until next Monday, Dec. 5.

The season opens on an optimistic note. Over the past five years, scallop landings have increased steadily, from just over 175,000 pounds of scallop meats (about 1.5 million pounds in the shell) during 2011 to almost 453,000 pounds in 2015.

As in the past several years, fishermen will have a 60-day season in state waters between the Maine-New Hampshire border and western Penobscot Bay (Zone 1), a 70 day season in the waters between eastern Penobscot Bay and the Lubec Narrows bridge (Zone 2) and a 50-day season in Cobscook Bay—the state’s most productive scallop fishing grounds.

Fishermen are subject to a daily possession limit of 15 gallons (about 135 pounds) of scallop meats in all state waters except Cobscook Bay where the daily limit is 10 gallons.

Because commercial fisheries landings are generally reported on an annual basis, it is can be difficult to tease out how well the fishery did during a single season which incorporates parts of two calendar years. Dealers can also be slow in reporting landings information.

That said, during the 2014-2015 fishing season Maine harvesters landed about 525,000 pounds of scallops worth some $6.5 million. Virtually all of those scallops came from state waters—inside the three-mile limit.

The number of active scallopers has increased steadily over the past seven years.

Effort to protect deep-sea coral has lobster industry on alert

November 28th, 2016 — Over 400 Maine lobstermen could lose their traditional fishing territory under a proposal to protect deep-sea corals in the Gulf of Maine.

The New England Fishery Management Council is considering a plan that would ban fishing in four designated coral zones spanning about 161 miles of federal waters in the Gulf of Maine – Mount Desert Rock, Outer Schoodic Ridge, Jordan Basin and Lindenkohl Knoll. Here, often on steep rock walls deep under water where sunlight cannot penetrate, scientists have found dense, delicate and slow-growing coral gardens of sea whips, fans and pens.

These coral habitats have become increasingly rare, suffering from centuries of damage from fishing gear. The council wants to protect these corals, which provide shelter, food and refuge to fish such as cod, silver hake and pollock, and serve as an essential habitat for larval redfish. A sister organization has already created deep-sea coral protection zones in deep mid-Atlantic waters from Long Island to Virginia.

Like most of the Gulf of Maine, the four coral zones under consideration here are home to lobsters. Two of the zones, Mount Desert Rock and Outer Schoodic Ridge, are prime fishing grounds for Maine lobstermen who fish offshore when the lobsters migrate to deeper waters, while the other two are primarily fished by southern New England lobstermen.

Wanted: Lobstermen willing to try out life vests

November 28th, 2016 — The Northeast Center for Occupational Health and Safety is asking New England lobstermen to help design a life jacket they would actually wear every day.

It could be a matter of life or death.

Researchers will visit Maine docks this winter to recruit fishermen to try out different kinds of personal flotation devices, or PFDs, for a month to determine which designs work best for daily use aboard a lobster boat. The lobstermen will be paid to test the life vest, and can keep it for their own use once they are done.

“This isn’t about making lobstermen wear anything, telling them what to do or regulating anything,” said principal investigator Julie Sorensen of the Northeast Center. “It’s about making PFDs comfortable enough that fishermen want to wear them.”

Statistics suggest it will be a hard sell, but well worth it.

In a study published this year, the Northeast Center found only 16 percent of lobstermen reported using a personal flotation device on the job, even though they know the risk of drowning. Falls overboard are the leading cause of workplace fatalities for New England lobstermen, accounting for 16 out of 29 on-the-job deaths from 2000 to 2015, according to the National Institute for Occupational Safety and Health.

None of the lobstermen who died from a fall overboard was wearing a life jacket, records show.
