June 10, 2020 — This novel use of drones is a promising way to remotely monitor these hard-to-see fish
Researchers have used an unmanned aerial system (or drone) to gather data on schooling juvenile Atlantic bluefin tuna in the Gulf of Maine.
This pilot study tested whether a drone could keep up with the tuna while also taking photographs that captured physical details of this fast-moving fish. The drone was equipped with a high-resolution digital still image camera. Results show that drones can capture images of both individual fish and schools. They may be a useful tool for remotely monitoring behavior and body conditions of the elusive fish.
Individual fish lengths and widths, and the distance between fish near the sea surface, were measured to less than a centimeter of precision. We used an APH-22, a battery-powered, six-rotor drone. The pilot study was conducted in the Atlantic bluefin tuna’s foraging grounds northeast of Cape Cod in the southern Gulf of Maine.
“Multi-rotor unmanned aerial systems won’t replace shipboard surveys or the reliance on manned aircraft to cover a large area,” said Mike Jech, an acoustics researcher at the Northeast Fisheries Science Center in Woods Hole, Massachusetts and lead author of the study. “They have a limited flight range due to battery power and can only collect data in bursts. Despite some limitations, they will be invaluable for collecting remote high-resolution images that can provide data at the accuracy and precision needed by managers for growth and ecosystem models of Atlantic bluefin tuna.”
June 5, 2020 — Researchers have projected significant changes in the habitat of commercially important American lobster and sea scallops along the Northeast continental shelf. They used a suite of models to estimate how species will react as waters warm. The researchers suggest that American lobster will move further offshore and sea scallops will shift to the north in the coming decades.
The study’s findings were published recently in Diversity and Distributions. They pose fishery management challenges as the changes can move stocks into and out of fixed management areas. Habitats within current management areas will also experience changes — some will show species increases, others decreases, and others will experience no change.
“Changes in stock distribution affect where fish and shellfish can be caught and who has access to them over time,” said Vincent Saba, a fishery biologist in the Ecosystems Dynamics and Assessment Branch at the Northeast Fisheries Science Center and a co-author of the study. “American lobster and sea scallop are two of the most economically valuable single-species fisheries in the entire United States. They are also important to the economic and cultural well-being of coastal communities in the Northeast. Any changes to their distribution and abundance will have major impacts.”
Saba and colleagues used a group of species distribution models and a high-resolution global climate model. They projected the possible impact of climate change on suitable habitat for the two species in the large Northeast continental shelf marine ecosystem. This ecosystem includes waters of the Gulf of Maine, Georges Bank, the Mid-Atlantic Bight, and southern New England.

During its April 14-15, 2020 webinar meeting, the New England Fishery Management Council received a presentation from the Northeast Fisheries Science Center on preliminary results from the Red Hake Stock Structure Peer Review meeting. It then received a progress report on management measures that are under development to rebuild the southern stock of red hake. The Council is scheduled to take final action on this rebuilding package in June.
Currently, red hake is assessed as two distinct stocks – one northern and one southern (see map). As part of the research track assessment, a working group was established to evaluate whether it is appropriate to continuing using this two-stock assumption or whether an alternative approach would be better.
The working group was made up of scientists from the Northeast Fisheries Science Center, state agencies, and academia. It met several times between November 2019 and February 2020 and examined red hake growth, maturity, spawning patterns, and other characteristics. The working group also was charged with evaluating how well the federal bottom trawl survey catches red hake and what that means for population assessments

Lisa Methratta is the fishery biologist for the Northeast Fisheries Science Center’s offshore wind team. She brings academic training and professional experience in ecological research to bear on the study of offshore wind interactions with fish and fisheries.
“I am interested in designing new approaches for studying the ecological effects of offshore wind in marine ecosystems,” says Methratta, who previously worked for NOAA Fisheries as the national aquaculture liaison in the Office of Protected Resources. One of her tasks there was to lead an agency-wide working group examining the risks to protected species posed by offshore aquaculture.
“Wind power and aquaculture will each interact with the marine ecosystem in unique ways, many of which we are still learning about,” Methratta says. “Innovative, scientifically rigorous research will enrich our understanding of these interactions and support a healthy ecosystem with sustainable fisheries and industrial development in the offshore zone.”
April 14, 2020 — Since the late 19th century, New England’s commercial Atlantic herring fishery was tied to both the canning industry and the lobster fishery, and the connections to today’s lucrative lobster industry continue. For this reason, changes in the herring industry have wide-reaching ripple effects.
The 2018 benchmark stock assessment revealed changes to stock health and concerns about trends in recruitment and spawning stock biomass. In fact, 2016 recruitment was the lowest on record at 1.7 million fish.
The 2018 landings, says Kirby Rootes-Murdy of the Atlantic States Marine Fisheries Commission, were 43,772 metric tons with an ex-vessel value of $23 million. In 2019, the quota was slashed by more than half.
By the end of 2019, preliminary figures say more than 12,700 metric tons of herring were landed, according to Min-Yang Lee of the Northeast Fisheries Science Center. The value was $9.45 million.
Suzannah Raber, owner of New England Fish Co, a bait company, says markets have shifted.
“We used to send herring to Canada,” says Raber. “But now, 95 percent of our herring goes to lobster bait. We catch it and distribute it.” These days, Raber’s company targets mackerel this time of year, then goes seining for herring in summer.

Two newly issued reports provide a snapshot of the Northeast U.S. Shelf Ecosystem. They look at everything from phytoplankton production at the bottom of the food web to the fishery harvests at the top. One report focuses on Georges Bank and the Gulf of Maine the other on the waters of the Mid-Atlantic Bight. These are the three major regions within the Northeast U.S. Continental Shelf Large Marine Ecosystem.
These annual reports are part of a larger, ongoing NOAA-wide initiative. It provides a consistent national approach to managing ecosystems that is flexible enough to accommodate regional needs. This Integrated Ecosystem Assessment approach is intended to help resource managers integrate physical, biological, economic, and social components of ecosystems into their decision-making. This will help them to balance trade-offs and determine which approaches are more likely to achieve their desired goals. The 2020 State of the Ecosystem Reports inform the New England and the Mid-Atlantic Fishery Management Councils.
“This approach has helped give the council structure with specific steps to define what our management goals and objectives are, figure out how we can address them, and understand what that means for areas such as economics,” said Brandon Muffley, a fishery management specialist at the Mid-Atlantic Fishery Management Council.
The State of the Ecosystem reports were produced by the Northeast Fisheries Science Center, with additional collaborators from academic research institutions, non-profit organizations, and state agencies.
March 23, 2020 — Fisheries biologists used to rely on fishermen to tell them where fish were spawning and when. Fish are attracted to specific areas at certain times of the year, and fishermen find those important spawning grounds because the fishing is easy and the females come up bursting with eggs.
“Historically, researchers try to get in a good relationship with fishermen,” said Timothy Rowell, a research biologist with the passive acoustic research group at the National Oceanic and Atmospheric Administration’s Northeast Fisheries Science Center in Woods Hole. “They have the best local knowledge of where (the fish) are aggregating and spawning.”
Although researchers still depend on fishermen, they also use ever more sophisticated technology to help them find and study fish in the immensity of the world’s oceans. That is true of a four-year $1.3 million study of spawning fish in the sprawling blocks of ocean southeast of Block Island that are zoned to build massive offshore wind farms.
NOAA, the state Division of Marine Fisheries, Woods Hole Oceanographic Institution and the University of Massachusetts Dartmouth School of Marine Science and Technology are all participating in the study, which is funded by the U.S. Bureau of Ocean Energy Management. The research is focused on what may be one of the last remaining major seasonal spawning gatherings in the Northwest Atlantic, according to the state Division of Marine Fisheries.
