Scientists Scramble to Help Bay Scallops Survive Climate Change

March 27, 2023 — Stephen Tettelbach was surveying the bay scallop population in Nantucket with colleagues late in the summer of 2019 when he got the call: A longtime friend and fisherman on Long Island reported a mass die-off of scallops in Peconic Bay, Long Island’s legendary fishery.

Tettelbach, head of the Peconic Bay Scallop Restoration Program at Cornell Cooperative Extension (CCE) in Suffolk County, New York, said his first response was denial. Peconic Bay’s prized shellfish had been thriving in June. In fact, it was supposed to be another banner season—commercial landings in the two preceding years had been the largest since 1994, topping 110,000 pounds.

But after returning to Long Island a few days later and setting out on his annual October surveys of Peconic Bay, an estuary nestled between eastern Long Island’s North and South Forks known for its pristine waters, lush eelgrass meadows, and scallops considered to be the best in the country, Tettelbach saw the devastation for himself. “There were almost no living scallops anywhere,” he remembers.

Once the country’s leading bay scallop fishery, Peconic Bay is now holding on for dear life. 2019 marked the first in a series of die-offs that has led to the collapse of one of the few remaining fisheries of wild bay scallops, whose native East Coast populations have declined dramatically in recent decades.

Coastal change in the Northeast is fast outpacing other areas, with summer water temperatures increasing at a rate more than twice the global average, according to research published in Global Change Biology in January.

US Northeast scallop supply staying flat but market will be tough to predict

March 21, 2023 — The scallop market will be hard to predict in 2023 as supplies stay flat and demand becomes the main influence on pricing pressure, Northern Wind CEO Ken Melanson told SeafoodSource.

Melanson, addressing the topic at the 2023 Seafood Expo North America, on behalf of his New Bedford, Massachusetts, U.S.A. company, said scallop prices haven’t followed their typical trajectory given the flat supply.

Scallops dying off in Long Island are ‘a cautionary tale’ for New England

January 24, 2023 — Once one of the largest fisheries on the East Coast, Peconic Bay scallops have faced near complete die-offs on Long Island since 2019.

A study by Stony Brook University shows this could be a cautionary tale for New England.

Christopher Gobler, a co-author and endowed chair of coastal ecology and conservation in the School of Marine and Atmospheric Sciences, used satellite thermal imaging and recorded scallop heartbeats to measure how less oxygen and warming waters put stress on shellfish populations.

Data shows over the past two decades, the Peconic Bay estuary — and the entire Northeast — are warming at rates during summer that far exceed global average; Gobler said, “about threefold higher.”

MAINE: Scallopers meet with DMR on tweaks to the commercial fishery

January 24, 2023 — Fishermen have seen sea scallops stacked on top of one another in flush beds on the ocean floor and then vanish time and again throughout the decades of commercial fishing. In 2009, when stocks and landings fell concerningly low in what had been hot spots, fishermen agreed to a Department of Marine Resources (DMR) request to close some areas for three years. Then, after more than 60 meetings with fishermen, led by the Maine Center for Coastal Fisheries, in Stonington, a 10-year state management plan was adopted in 2012.

State waters were divided into three scallop fishing zones, with Zones 1 and 3 operated under limited access areas and designated open fishing days for divers and draggers, while a three-year rotation of fishing sites was used in Zone 2. As a whole, scallopers were on board, even though it meant operating under rules that limited when and where draggers and divers could fish.

With that plan at an end, Melissa Smith, the DMR’s resource coordinator for scallops, met with scallopers in January in all three zones to get input to tweak the plan. However, changes to the Zone 2 rotational plan were the main discussion.

“I think we’ve got a hard-fought battle ahead of us,” said Machiasport fisherman Mike Murphy, who has fished under the Zone 2 rotation for a decade. He said he had been willing to try the rotational management plan when it was floated over 10 years ago. But scallop areas change with time all along the Maine coast and so does the fishermen’s catch. Now Murphy is not so sure, after experiencing crowded fishing spots in the open areas, something that also depletes the stock.

“You put 70 boats [in one spot] and we’re going to clear it,” he said. “A lot of us want to see the whole rotational management thing go away. That’s going to be our battle.”

Summer heat waves and low oxygen prove deadly for bay scallops as a New York fishery collapses

January 20, 2023 — A new study by Stony Brook University researchers published in Global Change Biology demonstrates that warming waters and heat waves have contributed to the loss of an economically and culturally important fishery, the production of bay scallops. As climate change intensifies, heat waves are becoming more and more common across the globe. In the face of such repeated events, animals will acclimate, migrate, or perish.

Since 2019, consecutive summer mass die-offs of bay scallops in the Peconic Estuary on Long Island, New York, have led to the collapse of the bay scallop fishery in New York and the declaration of a federal fishery disaster, with landings down more than 99 percent.

This study led by Stony Brook School of Marine and Atmospheric Sciences graduate Stephen Tomasetti, Ph.D., and Stony Brook University Endowed Chair of Coastal Ecology and Conservation Christopher Gobler, Ph.D., and a collaborative team of researchers reveals that extreme summer temperatures, becoming more frequent under climate change, exacerbate the vulnerability of bay scallops to environmental stress and has played a role in the recurrent population crashes.

MAINE: Maine’s scallop industry is offering fishermen new opportunities at sea

January 13, 2023 — Maine’s fishermen are facing numerous threats from climate change and changing ecosystems, and aquaculture offers a solution. The state’s wild fisheries have become very focused on the lobster industry, but farming sea scallops gives an opportunity to diversify the seafood harvesting business and increase resiliency for coastal communities built around seafood production.

The scallop aquaculture community is unique to Maine and composed of a variety of people and organisations, including fishermen farmers, marine extension programmes, community development financial institutions and research and outreach foundations.

MAINE: As Maine’s climate continues to change, so does its growing scallop farming industry

January 10, 2023 — When you work on the water in Maine, the cold months make for hit-or-miss days.

For Andrew Peters and his three-person crew, undocking from Buck’s Harbor Marina in Brooksville to tend to their scallops is a year-round venture.

It takes about 45 minutes by boat to get to the scallop farm. Along the way, Peters’ crew counts and cleans small scallops. The ones he was monitoring in in December were about an inch or so and needed another two years to grow to market size.

“All my life I wanted to work on the water and make a living working on the water, and when I was younger, I wanted to be a lobsterman,” Peters said while steering the boat through islets on Penobscot Bay.

Peters, who grew up in New York, said he lived near Portland and worked as a sternman on a lobster boat. He wanted to be a captain himself.

“I’ve been on a waitlist for eight years, and within the last 10 years I’ve realized there are other ways to make a living on the water and one day is to scallop farm,” Peters said.

But when you eat a scallop from Maine, chances are you are eating a wild caught scallop. The harvest of wild scallops happens normally in winter. Scallops also take a long time to grow, sometimes two to three years to reach a marketable size.

Atlantic scallop 2023 landings to decline with biomass slide

December 14, 2022 — The East Coast scallop fleet is expected to land around 25 million pounds in the 2023 fishing year – about half of the landings from 2018 through 2020 that exceeded 50 million pounds, according to the New England Fishery Management Council.

Those boom times were driven by exceptionally big 2012-2013 year classes of scallops. Now the 2022 survey results show biomass is at its lowest since 1999. Yet scallops are not overfished and the stock is healthy, although the biomass has been coasting down with lower recruitment since 2013, according to a summary of the council’s Dec. 5-9 meeting at Newport, R.I.

The 2023 scallop fishing year begins on April 1, and the council staff expects most fishing effort will focus around Georges Bank, shifting north from the Mid-Atlantic where recruitment has been below average.

Regulators see hard years ahead for the scallop fishery, New Bedford’s cash cow

December 10, 2022 — Scientists report that young scallops off the eastern seaboard have been struggling to grow to maturity for nearly a decade now, constraining one of the nation’s most lucrative fisheries to its lowest biomass in more than 20 years.

In a presentation before the New England Fishery Management Council on Wednesday, the council’s scallop analyst Jonathon Peros projected that the latest regulations adopted by the council will cap next year’s scallop harvest at 25 million pounds — a steep drop from a record harvest of 61 million pounds recorded just four years earlier.

Still, the projections are higher than a historic lull the scallop fishery experienced in the late 1990s, according to data collected by the National Oceanic and Atmospheric Administration. The fishery’s subsequent recovery followed a decision to close and monitor fertile scallop grounds and is now touted by NOAA as a “fishery success story.”
