Saving Seafood

MASSACHUSETTS: Gloucester must relentlessly promote locally harvested seafood

February 20, 2016 — Gloucester needs to be relentless in promoting the benefits of its locally harvested seafood, as well as the fishermen and processors that send it to market, a city official told the Fisheries Commission this week.

Economic Development Director Sal Di Stefano said the city is addressing the challenges of operating in the modern, international seafood market with a marketing strategy designed to promote the city, its fresh seafood bounty, its fishermen and its shore-side businesses to the seafood-consuming world.

“If we don’t do this, other people will,” Di Stefano told the commission Thursday night during a discussion on the city’s plans for the upcoming Seafood Expo North America show in Boston. “And they will try to take it from us.”

The city’s new branding campaign, “Gloucester Fresh,” is at the heart of the promotional strategy aimed at helping consumers identify seafood harvested from the waters around Cape Ann and landed in Gloucester while appreciating its nutritional and sustainable benefits.

Working with Salem-based Sperling Interactive, the city is developing a website that Mayor Sefatia Romeo Theken is scheduled to launch at the beginning of the Seafood Expo during the first week of March.

Warmer waters could change Cape Cod fisheries

February 15, 2016 — Hot water is fine for fish chowder and lobster bisque, but not so much for many fish in the sea.

The National Oceanic and Atmospheric Administration has unveiled a study of 82 species of fish, mollusks and crustaceans, ranking each on how they might fare under a regime of warming waters in the Northeast.

The authors, and there are quite a few, selected important commercial species, various forage fish of little economic import such as sand lances that are ecological heavyweights, and endangered species.

The amount of available data varies widely species by species, but the authors made their best assessments based on the estimated vulnerability of each animal to shifting climate. They weighed environmental factors that would be altered by climate change (water and air temperature, salinity, acidity, precipitation, the variance of those factors, sea level and ocean currents) vs. the species’ resilience (prey and habitat specificity, sensitivity to temperature, acidity, stock size, population growth rate, spawning cycle and mobility).

The ocean has been heating up, if not steadily.

“It depends on what period you’re looking over,” reflected lead author John Hare, director of NOAA’s Narragansett Laboratory. “I tend to look over a long period, since the 1880s, it’s up about two degrees Fahrenheit. We took all the information we know now and try to look forward to 2050.”

A new formula for whale preservation

February 17, 2016 — WOODS HOLE — From 750 feet above Northeast ocean waters, right whale researchers can easily pick out “Ruffian” for his many scars or “Baldy” for her lack of rough skin patches. Other right whales, though, may take hours to identify.

A new “face recognition” algorithm for right whales, however, announced recently by the National Oceanic and Atmospheric Administration, could lead to development of time- and money-saving software and eventually to greater preservation of a species whose global population is 520, right whale experts say.

The new algorithm, created in an international competition sponsored by NOAA Fisheries and the Natick software developer MathWorks, can identify right whale “faces,” or tissue patterns on the top of their heads, with 87 percent accuracy, according to Christin Khan, a NOAA Fisheries biologist and right whale aerial surveyor. Khan, who works in Woods Hole, pursued the idea of facial recognition software for the right whales, and researched how to get the algorithm built, through an online competition that began in August and ended in January.

The winning team, out of 364 entries, was from the software company deepsense.io, with offices in the United States and Poland.

The new algorithm is a first step to developing software for day-to-day use, Khan said. The algorithm, in its initial form, is for aerial photos only, not for photos taken from a boat, Khan said. But the potential is great and part of the growing use of technology to protect whales, several right whale experts said.

“Right now we’re living in the golden age of whale research in terms of technology,” Dave Wiley, research coordinator for Stellwagen Bank National Marine Sanctuary, said. “The things we’re doing now I couldn’t even have imagined 20 years ago. This Cape Cod area is probably at the forefront of all this stuff.”

New Video System Can Help Count Cod Population

February 16, 2016 — DARTMOUTH, Mass. (AP) — Researchers with the University of Massachusetts-Dartmouth say a new video system will help provide data to better inform management of New England’s beleaguered cod population.

UMass Dartmouth School for Marine Science and Technology scientists say their new video system will help assess the species in the Gulf of Maine. The system uses open-ended fishing net with video cameras mounted on its frame to take pictures of fish passing through.

The university says the scientists tested the system on Stellwagen Bank in January with good results.

Cod are one of the most important food fish species in the Atlantic, but the stock has collapsed. Cod fishermen caught more than 33 million pounds of the fish in 2001 and managed only about 5.2 million pounds in 2014.

NOAA Cuts Monitor Days for Massachusetts Lobstermen

February 16, 2016 — NOAA Fisheries has recalibrated its method for determining the requisite sea days of observer coverage for lobster boats, resulting in decreased coverage for Massachusetts-based lobstermen and increased coverage for those based in Maine in the final quarter of this fishing season.

The National Oceanic and Atmospheric Administration, responding to criticisms from Bay State lobstermen, re-allotted the number of sea-days after expanding the pool of vessels eligible for observer coverage to include all federally permitted lobster boats rather than just those holding limited-use, multi-species permits that require the filing of vessel trip reports (VTRs).

The result is that for the final quarter of the 2015 fishing season (Jan. 1 to March 31), Massachusetts lobstermen will have six sea-days of mandated observer coverage, down from the previously scheduled 18. Maine lobstermen, however, will see their mandated sea-days of observer coverage rise to 33 from the originally scheduled 14 in the same period.

The modified methodology also means that New Hampshire and Rhode Island lobstermen will have one day of mandated observer coverage respectively in the final quarter of the 2015, down from the previously scheduled five for New Hampshire and four for Rhode Island.

Amy Martins, manager of NOAA’s Northeast Fisheries Observer Program (NEFOP) that provides the observer coverage for lobster boats, said the new method for determining observer coverage will continue into the 2016 fishing season that begins May 1.

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.”

Ocean study demands new approach to fishery regulation

February 11, 2016 — Complexity is the confounding principle in the process of fishery regulation. It has led to confusion, acrimony, litigation and fear among the myriad stakeholders in the Northeast Multi-Species Fishery.

A study released last week by NOAA’s Northeast Fisheries Science Center in Woods Hole tackles complexity in a way that should empower regulators who are trying to balance conservation and economic goals, keeping the fishery profitable and preparing for an uncertain, changing ocean environment.

Regulators — the New England Fishery Management Council in the Northeast fishery — have been spinning their wheels until recently trying to respond to data about fish landings and species biomass without information that accurately depicts the changing environment.

Fish landings and biomass provide irreplaceable data for regulators to include in their decisions, but without scientific measurements on aspects of the broader environment — ocean temperatures, currents, salinity, acidity — it becomes less likely that prescriptions will be effective, and impossible to construct policies with any reach beyond a season or two of fishing. In other words, for fishing regulations to achieve intended goals, regulators cannot ignore the oceanic imbalance that has brought dramatic and rapid changes; their disruption of species’ behavior and biology is far beyond the limits of certainty, beyond the limits of traditional regulation.

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.”

Expert Says Shark Numbers May Double

February 9, 2016 — WELLFLEET — It might not seem it by looking out the window, but the Cape is closing in on another beach season, and members of a working group tasked with improving public safety given an increasing number of great white sharks visiting our shores each summer, are well aware that it’s time to focus on what is doable in the next few months.

With the possibility that the population of great white sharks in Cape waters could eventually double current estimates the sense of urgency is also on the rise.

For the most part, high tech solutions, like drones, are out, and the focus is on education.“We’re going to change human behavior and keep people close to shore,” Leslie Reynolds, chief ranger for the Cape Cod National Seashore, told the group at a meeting Tuesday at the Wellfleet Council on Aging.

Park personnel are in the initial stages of making an educational video they hope to play on community TV access channels, online on town websites, in their own visitor center, at chamber of commerce information booths and elsewhere.

Her staff is working on a sign that would clearly spell out the shark danger to beachgoers in the off-season when lifeguards are no longer on duty, Reynolds said.

She unveiled a new purple flag with a great white silhouette that would fly every day at lifeguard stands warning visitors that sharks could be in the water.

Massachusetts Division of Marine Fisheries shark researcher Gregory Skomal said the numbers of great whites coming to the Cape each year “continues to go up and it will continue to do so in the near future.”

NOAA Issues Climate Warning for Scallops

February 9, 2016 — NEW BEDFORD — “Sea scallops have a high vulnerability ranking,” reads a Feb. 3 announcement from the Northeast Fisheries Science Center, which operates in Woods Hole under the National Oceanic and Atmospheric Administration (NOAA). “Negative impacts are estimated for many of the iconic species in the ecosystem including Atlantic sea scallop, Atlantic cod and Atlantic mackerel.”

The NOAA study, formally known as the Northeast Climate Vulnerability Assessment, said Atlantic sea scallops have “limited mobility and high sensitivity to the ocean acidification that will be more pronounced as water temperatures warm.”

Water temperatures in Buzzards Bay have risen 4 degrees over the past two decades, for example, according to a recent study by the Woods Hole Oceanographic Institution and the Buzzards Bay Coalition.

Scallops are vital to New Bedford’s fishing industry. NOAA Fisheries announced last October that New Bedford, for the 15th year in a row, was the No. 1 port in the country in terms of dollar value of its catch. Much of that value, which totaled $329 million in 2014, comes from scallops.

The money has big local impacts. Eastern Fisheries captain Christopher Audette, for example, told visitors at an annual buyers’ tour in March 2014 that deck hands on his scallop boat had taken home more than $200,000 in 2013 — and that he had made even more than that.

Harbor Development Commissioner Richard Canastra, who has been instrumental to the Whaling City Seafood Display Auction since 1984, said this week that the scallop industry — and stock — continues to boom in New Bedford.

“The biomass has been increasing over the last 10 years, and there is no sign of it depleting because of the warmer waters,” Canastra said. “They’re talking a few degrees, and that’s not going to make much of a difference in terms of scallop population.”

Chad McGuire, associate professor of environmental policy at UMass Dartmouth, said that while the NOAA findings are not a surprise, they could be another “warning signal” for the industry.

“This study suggests that if you care about one of the largest economic drivers for this region, then you need to care about climate change,” said McGuire, whose work includes fishery management and climate change issues.

“We should be worried that this could greatly affect how many scallops we’re taking in the future,” he added.
