Saving Seafood

Ocean acidification may reduce sea scallop fisheries

September 24, 2018 — Each year, fishermen harvest more than $500 million worth of Atlantic sea scallops from the waters off the east coast of the United States. A new model created by scientists at the Woods Hole Oceanographic Institution (WHOI), however, predicts that those fisheries may potentially be in danger. As levels of carbon dioxide increase in the Earth’s atmosphere, the upper oceans become increasingly acidic—a condition that could reduce the sea scallop population by more than 50% in the next 30 to 80 years, under a worst-case scenario. Strong fisheries management and efforts to reduce CO2 emissions, however, might slow or even stop that trend.

The , published in the journal PLoS One, combines existing data and models of four major factors: future climate change scenarios, ocean acidification impacts,  policies, and fuel costs for fishermen.

“What’s novel about our work is that it brings together models of changing ocean environments as well as human responses” says Jennie Rheuban, the lead author of the study. “It combines socioeconomic decision making, ocean chemistry, atmospheric carbon dioxide, economic development and fisheries management. We tried to create a holistic view of how environmental changes might play out across different aspects of the  fishery,” she notes.

WHOI Center for Oceans and Human Health to Receive $6.9M in Grant Funding

September 19, 2018 — WOODS HOLE, Mass. — The Woods Hole Oceanographic Institution will receive nearly $7 million in grant funding to continue the operation of its Woods Hole Center for Oceans and Human Health.

The collaborative award from the National Science Foundation and National Institute of Environmental Health Sciences will be dispersed over 5 years.

The funding will benefit three centers and four projects aimed at improving public health by investigating the ways oceanic processes affect the distribution and persistence of human pathogens or the products of toxin-producing algae.

“These projects bring together scientists doing basic research on the oceans and Great Lakes with those in biology and human health to study processes that affect millions of people,” said Hedy Edmonds, a program director in NSF’s Division of Ocean Sciences, which co-funded the awards.

Senate Panel Told Nation’s Algae Woes Will Worsen If Not Addressed

August 29, 2018 — WASHINGTON — The spread of toxic algal blooms in the nation’s waterways – largely caused by a combination of warming water, contaminant run off and “supercharged bacteria” – won’t stop anytime soon, one scientist told lawmakers Tuesday.

During a Senate Commerce, Science and Transportation subcommittee hearing, scientist Donald Anderson of the Woods Hole Oceanographic Institution in Massachusetts, told lawmakers that after 40 years of study on toxic blooms, he is convinced that the outbreaks will only persist and worsen if left unaddressed.

The blooms vary greatly in composition and color; some are red, some green, and others gold.

In freshwater, the blooms are typically caused when simple algae collides with cynobacteria, or blue-green algae.

While some algae growth can be beneficial and the exact causes for emergent blooms vary in both fresh and marine water, Anderson said, it is climate change which will “almost certainly” continue to influence the pervasiveness of dangerous algal build up.

It’s ‘the last frontier on Earth that’s truly not well understood,’ and scientists are about to explore it

August 6, 2018 –In the briny deep, far from shore, the vast darkness is home to tiny, glowing fish, massive jellies that may be the largest animals on the planet, and an untold number of other creatures.

What inhabits this realm of the ocean — from about 600 feet to about 3,000 feet — is so shrouded in mystery that scientists call it the “twilight zone.”

At the end of the week, a team of marine biologists, engineers, and other specialists from the Woods Hole Oceanographic Institution will embark on the first long-term study of this netherworld, a nearly lightless region believed to be teeming with life — perhaps more than the rest of the ocean combined.

“It’s the last frontier on Earth that’s truly not well understood,” said Andone Lavery, a senior scientist who will oversee the first expedition. “We have many questions.”

Chief among them: What animals live there, and how many? Do they play a role in helping regulate the planet’s climate, and if so, how? Could these species provide a sustainable source of protein for the world’s growing population?

That last question may be the most controversial.

Senators share their fascination with sharks at hearing

July 19, 2018 — Lawmakers on Wednesday held a hearing on sharks to examine new research, conservation techniques and ways to improve understanding of the unique animals.

The hearing before the Senate Commerce, Science and Transportation Committee, titled simply “SHARKS!,” featured experts in shark research who told lawmakers how their discoveries are benefiting the medical and tech fields.

“Americans have been fascinated by sharks,” said Committee Chairman John Thune (R-S.D.). “Aquariums and other educational programs have helped to demystify sharks and our initial fear has turned into fandom.”

The hearing also comes just before the start of The Discovery Channel’s 30th annual “Shark Week,” which is set to begin July 22.

Dr. Robert Hueter, the senior scientist and director of the Center for Shark Research at the Mote Marine Laboratory in Sarasota, Fla., credited the annual television event with leading to a better understanding of the complex creatures.

Americans are now “rooting the shark on,” Hueter said.

“They understand that that shark is not really threatening them, they’re not looking for people, that they’re there trying to do their thing and they’ve been there for millions of years,” Hueter said.

MAINE: Return of the seals: Once eradicated mammals back in local waters

July 2, 2018 — At any given time, approximately 600 seals splash, bathe and feed around a modest mass of rocks six miles off the coast of Maine, the northernmost of the Isles of Shoals.

These seals, both gray and harbor species, have made a resurgence in local waters over the last two decades following the imperative enaction of federal protections. Prior to the 1970s, the species had essentially been extirpated in Maine and Massachusetts, after being hunted for their pelts, and killed as competition for fish, said Jennifer Seavey, executive director of Shoals Marine Laboratory on Appledore Island, a joint program between the University of New Hampshire and Cornell University.

Since 2011, Seavey and her staff have been monitoring the seal resurgence at Duck Island, an effort led by Andrea Bogomolni, a researcher from Wood’s Hole Oceanographic Institution. The work is conducted with undergraduate interns, and each summer, two students learn the monitoring methods, which are done by boat and with very specific tracking technology and procedures.

The monitoring program runs from May to August, Seavey said, and the interns take to the water approximately 30 times, the boat running a specific transect around the island. Photographs are taken on the same transects each time, where the laboratory uses the unique pattern on the seals’ fur to identify them as individuals.

No calves as right whales return to Nova Scotia from Florida

May 30, 2018 — Only 16 whale sightings were reported anywhere south of Virginia this winter. The lack of sightings, coupled with at least 18 whale deaths reported in Canada and the United States between April 2017 and January 2018, leaves those interested in right whales concerned.

Scientists studying the critically endangered North Atlantic right whale logged another depressing statistic this winter.

In the more than 30 years scientists have tracked the movements of the whales between New England and Nova Scotia and the warmer waters off the Florida coast, this was the first time no calves have been sighted. That fact has only added concern to the growing sense of urgency after right whale deaths skyrocketed last year.

“Obviously you can’t tell a right whale it’s time to have a baby,” said Michael Moore, a senior scientist at Woods Hole Oceanographic Institution and director of its marine mammal section.

But Moore and many other right whale scientists watching the highly endangered population dwindle before their eyes are seeking answers to the deadly perils the animals face, including collisions with the ships that share their space, commercial fishing gear that tangles the whales, and a warming ocean that appears to be wreaking havoc with their food supply and changing their migration patterns.

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.
