University of Massachusetts scientists improving cod counting technology

February 11, 2016 — A new video system designed by UMass Dartmouth School for Marine Science and Technology (SMAST) scientists to assess the population of cod has passed its first major test, giving the researchers confidence that they can use this new approach to help improve the accuracy of future scientific assessments of this iconic species. Recent stock assessments indicate that the Gulf of Maine cod population is low and struggling to recover. Members of the fishing industry contest those results, suggesting the stock is much healthier than depicted in recent assessments.

“Our goal is to provide all stakeholders in this issue with trustworthy science that leads to smart management of the Gulf of Maine cod fishery,’’ said Dr. Kevin Stokesbury, whose team conducted the test. “We are pleased with the initial results and are looking forward to scaling up our work.”

The Baker-Polito Administration provided $96,720 in capital money through the state Division of Marine Fisheries to fund research tows recently conducted on Stellwagen Bank. This work builds on similar research that Dr. Stokesbury’s team has conducted on yellowtail flounder, which is also facing difficulty. Of special note, Dr. Stokesbury’s approach has been successfully used over the last sixteen years to measure the scallop population of the east coast resulting in improved assessments integral to sustaining that fishery and keeping New Bedford the top-ranked fishing port in the U.S.

“The work by UMass Dartmouth School for Marine Science and Technology will complement work done by our federal partners by providing additional scientific data that will help us better understand what is happening to the cod stocks in New England,” said Governor Charlie Baker. “Improving the data used to make informed decisions is critical to preserving the economic viability of the Commonwealth’s fishing industry.”

The new video system uses an open-end fishing net with video cameras mounted on its frame to capture images of the fish passing through the net. Researchers then review the video to count the different species, and estimate the size of each fish.

The current practice of counting cod involves catching the fish in a net and hauling them onto the deck of the vessel, then counting, weighing and measuring them. Dr. Stokesbury believes this practice is less efficient because the nets are only left in the water for a short period of time (20-30 minutes), while the open-end net can be left underwater for hours at a time collecting a greater amount of data on fish populations across a larger portion of the ocean. In addition, the traditional survey method kills most of the fish that are caught, while the new open-net video method causes no damage to the fish.

The tests were conducted on Stellwagen Bank January 7 -9 aboard the F/V Justice, a New Bedford-based commercial fishing boat captained by Ron Borjeson. Dr. Stokesbury was joined on the excursion by graduate students Travis Lowery and Nick Calabrese, and technician Christa Bank.

The objectives of the test were to determine whether the video camera system design functioned properly; whether the video fish counts matched on-deck fish counts; and whether the system could be used to measure the population of cod in the area.

Eleven 30 minute tows with an open net were conducted, while seven half hour tows were made with a closed net. For closed net tows, the fish were carefully brought onto the boat, counted, measured, weighed, and returned to the sea. Fish survival was high due to the care shown by the research team.

A total of 6,423 fish, representing 21 species, were collected during closed tows, with the three most abundant species being haddock (2,062), yellowtail flounder (1,444) and Atlantic cod (1,096). Cod ranged from 28 cm (10 inches) to over 80 cm (32 inches). Numbers and size of each species observed during open net tows are currently being derived from video footage.

Biological samples of cod were collected for two collaborative research projects related to the genetics and evolution of cod. SMAST, Gulf of Maine Research Institute, University of New Hampshire, Massachusetts Division of Marine Fisheries and the Gloucester Marine Genomics Institute are participating in these studies.

“This experiment was successful beyond what I had hoped for,” Dr. Stokesbury said. “I was impressed with the abundance of cod and other species, particularly yellowtail flounder, winter flounder, and haddock.”

Maine Coldwater Shrimp Research Survey Harvests Fall Short of Predictions

February 10, 2016 — Maine shrimp lovers are hoping for the best this winter. With the shrimp population in decline over the past few years, and the Gulf of Maine shrimp fishery being closed for the third season in a row to shrimp trappers and trawlers, there won’t be much Maine shrimp in markets, restaurants or on dinner tables again this year.

But thanks to a study being conducted by the Atlantic States Marine Fisheries Commission (ASMFC) and the states of Maine, New Hampshire and Massachusetts, four trawlers and two trappers have been selected to collect samples of northern shrimp from the Gulf of Maine.

Marine biologists will use the data to determine the timing of the egg hatch, and the size, gender and developmental stage of the shrimp, according to biologist Margaret Hunter of the Maine Department of Marine Resources (DMR). A total catch of 48,500 pounds from the Gulf of Maine is being allowed. Any shrimp not used in the study may be sold by the fishermen.

Each participating trawler is required to conduct five research trips in one region, and is being compensated $500 per trip. Each would be allowed to sell up to 1,800 pounds of shrimp per trip.

The two shrimp-trapping vessels are required to continue hauling until the shrimp have hatched off all their eggs. Each is allowed 40 traps, and may haul as often as necessary during the project, with a 600-pound weekly catch limit. The shrimp may be sold, but there will be no other compensation for the trappers.

Despite the best efforts of local trapper Bill Sherburne, as of yet, the shrimp catch has not met his expectations.

As of Feb. 1, Sherburne said he hadn’t done as well as he had hoped. “It makes a difference where the traps are placed. They don’t come close to shore until the water cools down.”

Maine lobster industry wary as warm waters suggest repeat of disastrous 2012 season

February 4, 2016 — For those in the lobster industry, any sign of a return to the conditions of 2012 is cause for high anxiety.

Researchers say the industry needs to be prepared for that possibility because warming trends are laying the groundwork for a potential repeat of the disastrous season of four years ago.

“We learned a hard lesson in 2012,” said Patrice McCarron, executive director of the Maine Lobstermen’s Association.

Because of warm waters in the Gulf of Maine, peak harvesting started in May that year, weeks ahead of schedule. The catch jumped more than 20 percent, from 104 million pounds in 2011 to 127 million pounds in 2012. The shedding season, when lobsters lose their hard shells and grow new ones, typically happens in June and results in soft-shelled lobsters that are difficult to transport. In 2012, shedding began almost as soon as the lobstermen started pulling in traps, and extended into the fall.

As a result, prices paid to lobstermen fell to as low as $2 a pound.

Andrew Pershing, chief scientific officer at the Gulf of Maine Research Institute in Portland, said Thursday that the stage is set for a possible repeat of 2012, at least weather-wise.

Pershing said five buoys that measure water temperatures around the gulf are all running above average, and three are at record highs.

“The average surface temperature across the entire Gulf of Maine is now slightly warmer than during the 2012 ocean heat wave,” Pershing said.

MASSACHUSETTS: Delving into the deep

February 5, 2016 — Maritime Gloucester has embarked on an ambitious slate of programs for 2016, many designed as teaching tools providing information on a variety of topics within the overarching themes of ocean planning and innovation on the waterfront.

The working museum and maritime education center on Harbor Loop built the schedule — including the MGTalks and HarborLAB series — to provide relevant information to Cape Ann residents from all sides on maritime topics of local interest, ranging from fisheries to ocean exploration, said Melanie Murray-Brown, Maritime Gloucester’s director of program information. 

“We decided that we didn’t want to shy away from controversial topics,” Murray-Brown said Thursday. “We’re not advocating for any particular side on these issues, but providing the information more as a public service.”

The MGTalks series kicks off next Thursday, Feb. 11, at 7 p.m. at Maritime Gloucester with a free panel discussion on who owns the ocean and balancing interests while managing ocean sprawl.

The panel, including Bruce Carlisle, director of the state’s Office of Coastal Zone Management, and Jack Clarke, a Gloucester resident who is director of public policy and government relations for the Massachusetts Audubon Society, will discuss the formation and goals of the Massachusetts Ocean Plan.

The discussion is expected to include the roles of specific stakeholders and the areas of dissent on issues stretching from sand and gravel mining to the ramping up of the exploration for gas and oil near entry points to the Gulf of Maine by Canadian public and private interests.

John Sarrouf of the Gloucester Conversations project will moderate the panel.

Maine to pay for research in effort to keep lobster fishery healthy

February 4, 2016 — Maine’s lobsters are about to get new scrutiny.

The Department of Marine Resources has put out a call for proposals to gauge the impact of warming Gulf of Maine waters on lobster biology, populations and susceptibility to disease. A separate study will attempt to measure the economic impact of Maine’s most valuable fishery beyond what lobstermen are paid for their catch.

The department has earmarked up to $700,000 to pay for the studies, with the money coming out of the Lobster Research, Education and Development Fund. The money in that fund comes from sales of the lobster license plate.

Research proposals are due Thursday. The department’s request for proposals suggests the contracts will be awarded by early March, but department spokesman Jeff Nichols said the timing depends on how many proposals are received and how quickly a panel is formed to review them.

The department said it needs the research to determine how to help maintain the industry’s remarkable health over the past 20 or 30 years. Lobster landed in Maine was valued at a record $465.9 million in 2014, up more than fourfold in the past two decades. The catch by 5,818 commercial license holders made up 78 percent of the value of commercial fishery landings in the state.

Carl Wilson, director of the department’s Bureau of Marine Science, said “there are sufficient questions” about what’s happening with climate change and its impact on the Gulf of Maine to warrant more study.

New quotas cut deep for fishing industry

February 3, 2016 — Fishermen and fishing stakeholders say the darkness that has descended on the Northeast groundfish fishery over the past three years is only going to grow deeper in 2016, with some fishing stakeholders envisioning the final collapse of the small-boat industry due to slashed quotas for species they believe are abundant.

“With these cuts, we will not have a fishery as we know it anymore,” said Vito Giacalone, the manager of Gloucester-based Northeast Fishing Sector 4 and the policy director at the Northeast Seafood Coalition. “The great shame to this is we’re going to have this entirely detrimental economic impact while the stocks are in great shape and no one in the government is listening. There is just no leadership.”

At the heart of the issue is the expanding difference between what fishermen say they are seeing on the water and the results from NOAA stock assessments used to produce the annual fishing quotas. Call it a watery Great Divide.

“The fish are in great shape and the only real constraint on catch is quota,” Giacalone said. “Fishermen are seeing that across the board on a lot of the species.”

The quotas, set for 2016 by the National Oceanic and Atmospheric Administration in the final groundfish framework, reflect a far different analysis by NOAA and its scientists. They include savage cuts to gray sole (55 percent), Georges Bank cod (66 percent), northern windowpane flounder (33 percent) and Gulf of Maine yellowtail flounder (26 percent).

“We’ve never had a greater gap between what the fishermen are seeing on the water and what the scientists are saying,” Giacalone said. “Never.”

Gloucester fisherman Al Cottone said his personal sector contribution (PSC) for 2016 includes a slight increase in Gulf of Maine cod from the 1,800 pounds he was allotted in 2015, but cuts in several other species such as yellowtail flounder (down 25 percent to 2,400 pounds); American plaice (down 17.6 percent to 2,800 pounds) and gray sole (down 6 percent to 2,800 pounds).

Whale habitat change concerns fishermen

February 2, 2016 — GLOUCESTER, Mass. — NOAA Fisheries announced last week that it was expanding the critical habitat for endangered North Atlantic right whales to cover its northeast feeding areas in the Gulf of Maine and Georges Bank. The designated area is much larger than the one it replaces, and now includes all of the Gulf of Maine on the U.S. side of the national boundary with Canada.

The designation also was applied to an expanded area of the whales’ southeast calving grounds from North Carolina to Florida.

Under the Endangered Species Act, critical habitat within the range of the species consists of areas that contain physical or biological features essential to conservation of the species.

The final rule, which was first proposed in February 2015 and received 261 general comments over a 60-day comment period, does not include any new restrictions or management measures for commercial fishing operations. It does not create preserves or refuges.

However, federal agencies conducting, funding or permitting activities in these areas are required to work with NOAA Fisheries to avoid or reduce impacts on critical habitat.

The announcement has sparked long-standing disagreements between environmental and animal organizations and commercial fisheries.

Humane Society CEO Wayne Pacelle called the decision “a lifeline” for right whales in a blog post published Friday. “The HSUS and its allies have been fighting for an expansion of protected habitat since 2009, and it’s a victory for us over commercial fishermen and shipping interests that have irresponsibly downplayed their role in driving down the numbers of these mammoth creatures,” he wrote.

Herring vs. Haddock in Data Debate

February 3, 2016 — PORTLAND — Last October, the National Marine Fisheries Service (NMFS) drastically constrained the ability of midwater trawlers to fish for herring in offshore waters for a period of more than six months, because the herring fleet had bumped up against its quota for the incidental catch of Georges Bank haddock.

As a result, at its December meeting, the New England Fishery Management Council (NEFMC) heard a request from herring fishery interests to reconsider the level of constraint for the upcoming fishing year of May 1, 2016 to April 30, 2017, and for future years, since Georges Bank haddock appears to be plentiful and, they said, estimates of haddock catches by the herring fleet were inaccurate.

“A seven-month closure of a major fishery is very significant,” said NEFMC member Mary Beth Tooley, who is the government affairs representative for Rockland-based O’Hara Corp., which owns and operates two herring vessels. “We in the herring fishery don’t want to catch haddock. But that biomass is like locusts: They’re unbelievably abundant. It’s two-pronged: Let’s get groundfishermen catching haddock, and not close the herring fishery.”

Tooley said the herring industry agrees that there should be a limit on what the herring fishery takes from the haddock resource, and that accountability measures to enforce the limit are needed. But the methodology currently used to extrapolate estimates of how much haddock the herring fleet incidentally catches isn’t accurate, she said, and monitoring of harvesting operations, through observer or electronic programs, is inadequate for providing an accurate count of haddock catch.

“We need to have accountability,” Tooley said. “But with our current level of [observer] coverage…it’s become a real issue.”

In an action that became effective Oct. 22, 2015, herring midwater trawl vessels were prohibited from fishing for more than 2,000 pounds of herring per trip or day in the “Herring Georges Bank Haddock Accountability Measure Area,” a limit that will remain in place until the quota becomes available for the 2016 fishing year, on May 1.

The action effectively limited the midwater trawl fishery in Herring Management Area 3, because Area 3 falls within the Georges Bank Haddock Accountability Management Area.

Federally permitted herring vessels, all together, are allowed to catch 1 percent of the Georges Bank haddock resource. The overall allowable haddock catch on Georges Bank for 2015 was 53.7 million pounds (24.3 metric tons); 1 percent, which is further reduced a bit to account for management uncertainty, is 500,449 pounds (227 mt), according to NMFS.

According to data reported on Dec. 21, 2015, based on estimated haddock catches, the herring midwater fleet had reached 93.09 percent of its quota by September, and 104.49 percent by October.

The amount of haddock caught by the herring fleet is extrapolated from the amount of haddock caught on observer trips.

Why the U.S. East Coast could be a major ‘hotspot’ for rising seas

February 1, 2016 — New research published Monday adds to a body of evidence suggesting that a warming climate may have particularly marked effects for some citizens of the country most responsible for global warming in the first place — namely, U.S. East Coasters.

Writing in Nature Geoscience, John Krasting and three colleagues from the Geophysical Fluid Dynamics Laboratory of the National Oceanic and Atmospheric Administration find that “Atlantic coastal areas may be particularly vulnerable to near-future sea-level rise from present-day high greenhouse gas emission rates.” The research adds to recent studies that have found strong warming of ocean waters in the U.S. Gulf of Maine, a phenomenon that is not only upending fisheries but could be worsening the risk of extreme weather in storms like Winter Storm Jonas.

“When carbon emission rates are at present day levels and higher, we see greater basin average sea level rise in the Atlantic relative to the Pacific,” says Krasting. “This also means that single global average measures of sea level rise become less representative of the regional scale changes that we show in the study.”

In the new research, the scientists used a high powered climate change model based at the Geophysical Fluid Dynamics Laboratory in Princeton, N.J., that simulates the ocean, the atmosphere and the cycling of carbon throughout the Earth system. The goal was to determine how much sea level rise would occur in the Atlantic, versus the Pacific, under a variety of global carbon emissions scenarios.

Maine Shrimp Hitting Market Thanks to Spawning Study

PORTLAND, Maine — January 29, 2016 — Despite a moratorium on the northern Maine shrimp fishing season for the third consecutive year, a few wholesale buyers, restaurants, and markets could have some Maine shrimp on their hands — and plates — this winter, due to a scientific study currently underway throughout the state.

Fisheries regulators have closed the northern Gulf of Maine shrimp fishery every year since 2014, saying the shrimp population has dipped to an unsustainable low level.

Northern Maine shrimp is now considered by the regulatory committee to be “collapsed,” and a 2015 report indicated that from 2012 through 2015, the Maine shrimp population was the lowest on record during the 32 years that scientists have collected data.

However, this week, some Maine fishermen have been harvesting Maine shrimp from traps and trawlers as part of a sampling project being conducted by the Atlantic States Marine Fisheries Commission’s Northern Shrimp Technical Committee— a regulatory panel that manages the fishery — as well as other agencies including the Maine Department of Marine Resources and the School of Marine Science at the University of Maine in Orono.
