New study compiles Gulf of Maine seasonal wildlife timing shifts

April 24, 2019 — Many researchers and amateur naturalists keep track of dates for the first robin of spring, the first peepers or ice-out on ponds, and such records can offer decades of data on the timing of plant and animal life cycle events known as phenology.

While such observations are common in terrestrial systems, a new report by first author Michelle Staudinger and others at the University of Massachusetts Amherst shows there is a limited understanding of similar events in the oceans. They urge more researchers to increase observations and use more phenological datasets to understand how marine species are responding to climate change through phenological shifts in the Gulf of Maine and other coastal regions.

Staudinger says, “We only found 20 studies documenting shifts in phenology in the Gulf of Maine. This topic appears to have received less attention in the region compared to other responses to climate change. We provide a summary of the existing evidence and offer examples of the implications, remaining research questions and available long-term datasets appropriate for assessing shifts in the region. These data come from a range of federal, state, academic and citizen science monitoring programs.”

Federal Shutdown Halts Some Environmental Conservation Efforts, Slows Others

January 9, 2019 — Federal researchers in western Massachusetts study ways to protect migrating fish, backyard birds and urban trees. The government shutdown is keeping them home and away from their research.

The researchers work for agencies like the USDA Forest Service and the U.S. Geological Survey.

Curt Griffin heads the UMass Amherst Department of Environmental Conservation, where some of the scientists are based.

“It’s a very, very unfortunate event that our federal colleagues are caught up in this mess,” Griffin said. “And it’s not fair to them. It’s not fair to the public that they provide important services to. So it’s just a very broken system, and they’re caught in the middle.”

Massachusetts: UMass placing sustainable fisheries professor at Hodgkins Cove

December 21, 2017 — The University of Massachusetts at Amherst embarked on recasting the role of its Gloucester Marine Station at Hodgkins Cove by hiring Gloucester resident Katie Kahl to serve as the liaison between research elements at the school and the Cape Ann community.

The university’s School of Earth and Sustainability is set to formally announce the appointment of Kahl on Thursday to the newly created position of extension assistant professor in sustainable fisheries and coastal resilience.

“I’m really excited and can’t wait to start,” Kahl said Wednesday. “This is really a great opportunity for the university to re-imagine its role at the Gloucester Marine Station.” Kahl’s mission, which begins Jan. 2, is a new one for the university’s research facility.

The university announced last January that it was establishing a permanent, full-time extension faculty position at the Gloucester Marine Station as the focal point for determining the future role of the facility.

Most recently, it housed the university’s Large Pelagics Research Center, which was nicknamed the “Tuna Lab.” Under the guidance of Molly Lutcavage, the center did internationally groundbreaking research on giant bluefin tuna and other highly migratory pelagic species.

MASSACHUSETTS: Cape fishermen push dogfish, skate at expo

March 23, 2017 — Chatham fishermen Charlie Dodge, Jamie Eldredge, and Greg Connors walked the crowded aisles of the Seafood Expo North America Monday, one of the largest seafood shows in the world, drawing more than 21,000 attendees and exhibitors over three days.

The men were there to meet wholesale fish buyers and distributors looking to market their catch: skates — a kite-shaped fish related to sharks — and dogfish, a small coastal shark.

Dogfish and skates may not be ready to join heavyweights like salmon and shrimp, but with help from the Cape Cod Commercial Fishermen’s Alliance, as well as federal and state grants to assist with marketing, they are slowly gaining a foothold in domestic markets.

“It would be way better if it stays within the country,” Dodge said of dogfish, which, like skates is largely exported to Europe and Asia, and fetch relatively low prices, with skates at 23 cents per pound on average in 2015 and dogfish fluctuating between 11 cents and 22 cents per pound. In 2015, cod, by comparison, averaged $1.90 per pound.

Not long ago Chatham was one of the top cod ports in the country, but that stock is considered to be at historically low levels and landings state-wide collapsed from 27.5 million pounds in 2001 to 2.9 million pounds in 2015. Both skates and dogfish are plentiful and considered sustainably managed by organizations like the Gulf of Maine Research Institute, the Marine Stewardship Council and Seafood Watch. That message — a local, sustainable and affordable fish — has helped convince institutional clients like the University of Massachusetts in Amherst.

UMass’s award-winning dining halls serving up tasty dogfish as chefs reject ‘trash fish’ moniker

January 27, 2017 — AMHERST, Mass. — It may not have the tastiest name, but a University of Massachusetts chef says dogfish is becoming a popular fish on campus.

All the dining commons serve the fish — 400 to 500 pounds of it — as part of a fish fry every Friday night.

Bob Bankert, chef de cuisine for UMass Dining, said UMass began seeking alternatives to cod several years ago, and began serving dogfish in the fall.

“Cod is way over fished,” Bankert said.

Before arriving at dogfish, the dining halls also began serving other so-called “trash fish” such as pollock and redfish.

But Bankert rejects the “trash fish” moniker — born from the practice of fisherman tossing such species out instead of bringing them to market — and instead calls fish like dogfish “under loved.”

Bankert said people don’t have problems with the idea of eating catfish — but some balk at the name “dogfish.”

Dogfish — a shark species also known as “cape shark” — is native to New England waters. But, about 90 percent of the harvest has been sent to England for that country’s fish and chips, Bankert said.

He’s hoping that through word of mouth and focus on the fish, more people will try it and be able to find it at markets.

New England’s 1816 ‘Mackerel Year’ and climate change today

January 19, 2017 — Hundreds of articles have been written about the largest volcanic eruption in recorded history, at Indonesia’s Mt. Tambora just over 200 years ago. But for a small group of New England-based researchers, one more Tambora story needed to be told, one related to its catastrophic effects in the Gulf of Maine that may carry lessons for intertwined human-natural systems facing climate change around the world today.

In the latest issue of Science Advances, first author and research fellow Karen Alexander at the University of Massachusetts Amherst and 11 others including aquatic ecologists, climate scientists and environmental historians recount their many-layered, multidisciplinary investigation into the effects of Tambora on coastal fish and commercial fisheries.

Alexander says, “We approached our study as a forensic examination. We knew that Tambora’s extreme cold had afflicted New England, Europe, China and other places for as long as 17 months. But no one we knew of had investigated coastal ecosystems and fisheries. So, we looked for evidence close to home.”

In work that integrates the social and natural sciences, they used historical fish export data, weather readings,  and town growth chronologies and other sources to discover Tambora’s effects on the Gulf of Maine’s complex human and natural system.

The 1815 eruption caused a long-lasting, extreme climate event in 1816 known as the “year without a summer.” As volcanic winter settled on much of the Northern Hemisphere, crops failed, livestock died and famine swept over many lands. In New England, crop yields may have fallen by 90 percent. The researchers found that 1816 was also called “the mackerel year,” a clue to what they would find regarding fisheries.

Besides Tambora’s climate effects, the authors examined other system-wide influences to explain observed trends. These included historical events such as the War of 1812, human population growth, fish habitat obstruction due to dam building and changes in fishing gear that might have affected fisheries at the time. Employing historical methods in a Complex Adaptive Systems approach allowed them to group and order data at different scales of organization and to identify statistically significant processes that corresponded to known outcomes, Alexander says.
