SONIA FERNANDEZ: Doing right by the whales

June 12, 2018 — These are not good times for the North Atlantic right whale. Ship strikes and gear entanglement play major roles in the mortality of these highly endangered mammals, which now number fewer than 500. Making matters worse, climate-mediated shifts are pushing their prey out of the whales’ usual feeding grounds, rendering traditional habitat-focused protection policies less than optimal.

This reality was starkly apparent in the summer of 2017, when 17 turned up dead in U.S.-Canadian waters—a mass mortality event attributed in large part to gear entanglement and ship strikes. The event also revealed that the whales had gone beyond their typical distributional boundaries. Scientists estimate that unless protective policies are expanded to cover their shifting distribution, right whales may face extinction in less than 30 years.

That’s according to a new study by researchers including UC Santa Barbara Marine Science Institute ecologist Erin Meyer-Gutbrod. With atmospheric scientist Charles H. Greene, of Cornell University, and postdoctoral research associate Kimberley T. A. Davies, of Dalhousie University, Meyer-Gutbrod authored the paper “Marine Species Range Shifts Necessitate Advanced Policy Planning,” which appears in the journal Oceanography.

According to the group’s findings, “only five calves were born in 2017 and no newborn calves have been sighted thus far in 2018.”

“What we have seen with prey limitation is that whales will search outside of their traditional feeding grounds, looking for denser aggregations of zooplankton,” said Meyer-Gutbrod, who studies the effects of environmental change on right whale populations. Due to the northward movement of their food from their usual Gulf of Maine feeding grounds to the Gulf of St. Lawrence in Canadian waters, the whales, too, are shifting away from their usual habitats and into unprotected regions. The combination of food scarcity in their usual habitat and lack of protection in their adopted feeding grounds, Meyer-Gutbrod and colleagues say, calls for advanced policy planning that essentially follows these whales as they stake out new territory.

“Prey limitation is not typically so severe that right whales starve to death,” said Meyer-Gutbrod. However, she explained, when prey is scarce, adult females don’t have enough energy to reproduce successfully. In addition, when the whales move from their typical protected waters into heavily-trafficked and unprotected areas, they encounter a minefield of obstacles, from commercial shipping vessels to crab and lobster fishing gear.

Author Christopher White asks, is it ‘Boom or Bust for Maine’s Greatest Fishery?’

June 11, 2018 — Christopher White’s new book, “The Last Lobster: Boom or Bust for Maine’s Greatest Fishery?” landed on our desk with an ominous thump a couple of weeks ago. We called him in Santa Fe, where he’s living, to ask about how he reported his book (especially as an out-of-stater), what he finds to be optimistic about, and the role climate change plays in the future of lobstering. He also confessed to scheduling an interview at his favorite restaurant on Vinalhaven specifically for the lobster.

POP-UP STORY: White has written five books. The most recent were about fishermen (“Skipjack,” the story of the last days of a particular kind of wooden boat used for commercial fishing, specifically oyster dredging) and disappearing glaciers (“The Melting World”). For this book, he deliberately sought out a story that combined both those interests. “I looked for a story about how commercial fishing was affected by climate change. The first one that popped up on the map was the Gulf of Maine and lobstering.”

TEEN YEARS: Maine wasn’t new to White; he’d come to the state as a teenager. “I spent a lot of time in Maine, not only on the coast but at Rangeley and Lake Moosemeguntic.” He’s also a sailor, and he crewed on small boats as a young man as well. “I crewed from Camden to Vinalhaven, for example.” When he arrived in Maine to start reporting, “it was very interesting to go some of the places that I had visited at 16.” An old favorite was Vinalhaven, where he revisited his deep affection for the Harbor Gawker. “I conducted an interview there just so I could have lunch.” (The family that owned it for 40 years sold it, and a new restaurant, The Nightingale, is in the midst of opening.)

Cape Cod researchers use robots to monitor red tide

June 4, 2018 — Leaning over the side of a small skiff in Salt Pond, Woods Hole Oceanographic Institution researcher David Kulis shook the excess water out of a plankton net, then emptied the contents into a water bottle.

The gold tint to the water, he said, was likely Alexandrium, single-cell algae that produce a powerful neurotoxin. When concentrated in shellfish meat that feed on algae, the toxin can paralyze respiratory muscles in humans, a condition known as paralytic shellfish poisoning, which can be fatal.

Kulis and Northeastern University intern Taylor Mannes were using the tools plankton researchers had relied on for decades: a windsock-shaped net, with fine mesh to capture the single-celled organisms, and a Niskin bottle, originally developed in 1894 for polar research to retrieve samples at discrete depths. Lowered by hand to marks on a line corresponding to various depths, its opening is closed by sliding a lead weight down the line.

But with human health and a burgeoning shellfish and aquaculture industry in the balance, red tide research has gone decidedly high-tech. Sophisticated instruments are now deployed offshore in the Gulf of Maine and at inshore sites like Salt Pond in North Eastham.

Salt Pond is a natural laboratory, said Michael Brosnahan, a red tide researcher at WHOI. It already has a native population of red tide cells that survive the harsh New England winter as hardened cysts on the bottom of the pond. The incoming tide also pushes additional cysts from the larger marsh down a narrow creek and deposits them in deeper water in the pond, beyond the reach of the outgoing tide.

Red tide algae produce food through photosynthesis, and when the cysts hatch in the spring, they swim up into sunlit waters between five feet and eight feet deep. They remain at depths below the outlet creek channel, and relatively few of the free swimming cells are swept back out into the marsh by the tide.

MAINE: As clam harvesting declines, could farming be the answer?

June 3, 2018 — John Hagan surveys a vast field of tidal mud and envisions a place where farmers will one day rake clams in a way that more closely resembles harvesting potatoes or carrots than shellfish.

Whether New England’s long history of harvesting clams endures might hinge on whether the bold plan works.

The region’s annual haul of clams is in decline, and Hagan, president of the Massachusetts-based sustainability group Manomet, is among the people who want to save it by encouraging the industry to try turning to a new model — farming.

“This is a climate change story. The warming Gulf of Maine brings more crabs, and increasing crabs is what we think is playing a role in the diminishing soft-shell clam population,” Hagan said. “Can we beat the green crabs? I don’t have a hard answer.”

Northeast longfin squid earns MSC certification

May 29, 2018 — The Northeast inshore longfin squid fishery became the first squid fishery in the world to achieve Marine Stewardship Council certification this week as independent certifier SCS Global Services wrapped up an 11-month-long detailed assessment.

The fishery takes place along the East Coast from the Gulf of Maine to Cape Hatteras, N.C. Squid are harvested by small-mesh bottom trawls by the fishery client group Lund’s Fisheries of Cape May, N.J., and the Town Dock of Narragansett, R.I., along with independent fishermen throughout the region. The bottom trawl fishery for longfin squid follows the species’ seasonal inshore/offshore migration patterns.

“We are excited to build additional trust with our customers through MSC’s certification of our longfin squid fishery,” said Wayne Reichle, president of Lund’s Fisheries. “This certification demonstrates that our domestic fisheries management system is working to sustainably manage our major squid fishery to the benefit of the resource, fishing communities, and calamari lovers everywhere.”

“All of us at the Town Dock are excited to be part of such a historic initiative,” said Ryan Clark, CEO of the Town Dock. “Our goal has always been to provide customers with a healthy and sustainable product. By certifying longfin squid, we hope to take the promise of sustainability a step further by protecting the fishery to ensure consumers have access to squid now and for many years to come.”

Climate change to have drastic effects on Gulf of Maine lobster and clam fisheries, studies say

May 23, 2018 — AUGUSTA, Maine — Two new scientific studies are highlighting the current and future impacts that rising ocean temperatures will have on lobster, clams and other important commercial fisheries in the Gulf of Maine.

Research on nearly 700 North American fish species predicts Atlantic cod habitat could shrink by as much as 90 percent by century’s end and that lobster populations could shift 200 miles farther north as a result of climate change. Meanwhile, a separate research project suggests Maine’s soft-shell clam industry could collapse unless steps are taken to protect the fishery from green crabs that are thriving in the state’s warming waters.

“Something is out of whack and we need to do something about it. We need to adapt,” said University of Maine professor Brian Beal, who has studied soft-shell clams for more than 30 years.

The studies are part of a growing body of scientific work seeking to understand – and look beyond – changes that fishermen across the country are witnessing on the water every day.

New England groundfishery gains MSC certification

May 17, 2018 — The haddock, pollock, and Acadian redfish trawl in the U.S. Gulf of Maine and Georges Banks officially received MSC certification on 10 May.

Two companies, Fisherman’s Wharf based in Gloucester, Mass.; and Atlantic Trawlers based in Portland, Maine; worked to receive the certification. After roughly a year and extensive assessments the fishery was approved as sustainable.

“With the MSC certification, the fishery can guarantee that the fish stocks are healthy, the fishery has minimal impact on the marine ecosystem, and there is effective, responsive, and responsible management in place,” MSC spokesperson Jackie Marks said.

Certification allows the two companies to use the MSC blue ecolabel on their products, something that the owners of both Atlantic Trawlers and Fishermen’s Wharf saw as a good way to expand their market reach.

Scallop RSA Program: NEFMC and NOAA Announce 15 Awards Selected for 2018-2019 funding

May 16, 2018 — The following was released by New England Fishery Management Council:

 

The New England Fishery Management Council and NOAA Fisheries’ Northeast Fisheries Science Center (NEFSC) are pleased to announce that 15 projects have been selected for 2018-2019 funding through the Sea Scallop Research Set-Aside (RSA) Program.

“The Scallop RSA Program truly has become one of the flagships of the scallop fishery,” said New England Council Chairman Dr. John Quinn. “The collaborative efforts that take place at sea between fishermen and researchers go a long way toward enhancing our understanding of what’s happening with the resource. The results of this RSA work funnel back to the Council and support stock assessments. Without a doubt, the RSA program helps us better manage our – Virginia Institute of Marine Science photo extremely valuable scallop fishery.”

Projects will address research priorities established by the Council, with a particular focus on resource surveys. The awards are expected to generate more than $12 million: $3 million to fund research; and $9 million to compensate industry partners who harvest set-aside quota

“We are excited to be able to work with the New England Fishery Management Council, industry, and scientists to fund sea scallop science through the Research Set-Aside Program,” said NEFSC Science and Research Director Dr. Jon Hare. “The projects funded support surveys, bycatch mitigation, and biological studies, all with the purpose of improving the information used in the management of the sea scallop resource.”

The New England Council established the Sea Scallop RSA Program to address research questions that support management of the scallop resource. The Council sets the research priorities and researchers compete for funding through a federal grant competition managed by NOAA Fisheries.

No federal funds are provided to support the research. Instead, projects are awarded pounds of scallops, which have been “set aside” from the annual fishery quota for this purpose. Successful applicants partner with the fishing industry to harvest their set-aside award to generate funds for the research. There are active research set-aside programs for Atlantic sea scallops, Atlantic herring, and monkfish.

2018-2019 Scallop RSA Award Summary

The awards fall into three categories: scallop surveys (dredge, drop camera, and HabCam); bycatch mitigation; and sea scallop biology.

Scallop Surveys

The Virginia Institute of Marine Science (VIMS) received new awards to conduct dredge surveys in Closed Area I, Closed Area II, and the Nantucket Lightship. Under an existing award from last year, VIMS also will conduct a dredge survey of the Mid-Atlantic Bight. As part of ongoing efforts to better understand scallop survey dredge performance, VIMS investigators received an award to evaluate the hydrodynamic characteristics of both lined and unlined survey dredges in the largest flume tank in the world, located in St. John’s, Newfoundland at Memorial University’s Marine Institute.

The University of Massachusetts, Dartmouth School for Marine Science and Technology (SMAST) received three awards to conduct surveys using a drop-camera array. Through these awards, researchers plan to conduct high-resolution surveys of the Nantucket Lightship, Closed Area I, Great South Channel, and select portions of the Northern Gulf of Maine Scallop Management Area.

The Woods Hole Oceanographic Institution (WHOI) will conduct Habitat Camera Mapping System (HabCam) optical surveys throughout the Mid-Atlantic Bight and on the northern flank of Georges Bank. In addition to these surveys, researchers will continue to evaluate dredge effects on habitat and habitat recovery in the Closed Area II Habitat Area of Particular Concern. Coonamessett Farm Foundation will conduct a HabCam survey of the Nantucket Lightship and Southern Flank of Georges Bank.

Bycatch Mitigation

Coonamessett Farm Foundation will continue its seasonal survey on Georges Bank, collecting information on bycatch rates for yellowtail flounder and other species relative to scallop meat yield. These data also will be used to evaluate sea scallop health and meat quality, biological questions about several flounder species, and to examine lobsters for shell disease.

Coonamessett Farm Foundation will continue its loggerhead sea turtle tagging program, receiving funds to tag up to 20 loggerheads with water activated tags. Tag data will be used to evaluate spatial and temporal overlap between loggerhead sea turtles and the scallop fishery.

Coonamessett Farm Foundation also will be testing a dredge twine-top cover net in an attempt to quantify dredge selectivity characteristics.

Sea Scallop Biology

The Virginia Institute of Marine Science will investigate sea scallop density-dependence factors that may be affecting growth, mortality, and reproduction of scallops in the Nantucket Lightship and Elephant Trunk areas. In addition, VIMS will conduct a pilot study to extend the current stock assessment model to better account for sea scallop ages with a particular focus on the Mid-Atlantic Bight and Nantucket Lightship areas.

WHOI will receive support to determine if a gonadosomatic index (GSI) can be calculated from Light Field 3D images of shucked scallops collected during fishing operations. The GSI is used to assess maturity and spawning events in many species of fish and shellfish, including scallops. If successful, this could improve the ability to collect and quantify scallop maturation and spawning data during the course of routine fishery sampling procedures.

NEFMC: Cod Stock Structure Symposium – June 19, 2018, Registration Information

May 15, 2018 — The following was released by the New England Fishery Management Council:

New Hampshire Sea Grant and the University of New Hampshire (UNH), in conjunction with a steering committee, are hosting a symposium on the structure of Atlantic cod populations in the Gulf of Maine and Southern New England regions, as well as nearby Canadian waters, namely Georges and Brown Bank and the Scotian Shelf. Fishermen are encouraged to attend.

EVENT TITLE:  “Cod Population Structure and New England Fisheries Symposium: Furthering our understanding by integrating knowledge gained through science and fishing”

DATE AND LOCATION:  Tuesday, June 19, 2018 from 8:00 a.m. to 5:00 p.m. on the UNH Campus at the Elliot Alumni Center. Light breakfast, lunch, and snacks will be provided. Travel expenses may be provided for fishermen who are attending.

WHAT’S THIS ABOUT:  According to the steering committee, the symposium will provide an opportunity to explore and talk about “the current understanding of the stock structure of cod.” New information from recent scientific studies will be discussed, and recreational and commercial fishermen will share on-the-water experience and knowledge. The symposium will help: (1) identify areas of common ground in the understanding of cod population structure; (2) identify areas of remaining uncertainty; and (3) broaden knowledge of alternative management options that may be considered in the future to accommodate the evolving understanding of cod stock structure. The steering committee said, “The symposium contributes to a new process focused on reevaluating cod stock structure in U.S. waters.”

SYMPOSIUM OBJECTIVES:

  • Present recent findings among regional scientists studying Atlantic cod stock structure in U.S. and adjacent Canadian waters.
  • Capture insight and feedback from fishermen on what is being observed on the water to incorporate into the developing model by researchers.
  • Identify areas of common ground in the understanding of cod population structure and areas of remaining uncertainty.
  • Learn about a series of alternative management options that may be considered in the future to accommodate the evolving understanding of cod stock structure.

REGISTRATION INFORMATION:  Sign up at Cod Population Structure Symposium.

QUESTIONS ABOUT THE SYMPOSIUM:  Contact Erik Chapman, New Hampshire Sea Grant Director, at (603) 862-1935, Erik.Chapman@unh.edu.

COD STRUCTURE WORKING GROUP:  The symposium will precede a June 20-21, 2018 meeting of the Atlantic Cod Stock Structure Working Group. The working group was formed in February 2018 to “determine the most appropriate representation of Atlantic cod stock structure for use in regional stock assessments based on currently available information.” Background on the group is available at Working Group Formation Plan. The list of working group members and upcoming meetings can be found at Atlantic Cod Stock Structure Working Group.
