Saving Seafood

Clammers digging through pandemic, but shellfish are fewer

April 19, 2021 — Chad Coffin has spent the coronavirus pandemic much as he has the previous several decades: on the mudflats of Maine, digging for the clams that draw tourists to seafood shacks around New England.

But he’s running into a problem: few clams.

“There just isn’t the clams that there used to be,” Coffin said. “I don’t want to be negative, I’m just trying to be realistic.”

It’s a familiar problem experienced by New England’s clamdiggers. More New Englanders have dug in the tidal mudflats during the last year, but the clams aren’t cooperating.

The coronavirus pandemic has inspired more people in the Northeastern states, particularly Maine and Massachusetts, to dig for soft-shell clams, which are also called “steamers” and have been used to make chowder and fried clams for generations. The era of social distancing during the coronavirus pandemic is conducive to the often solitary work, said Coffin, the president of the Maine Clammers Association, which represents commercial clammers.

But the U.S. haul of clams has dipped in recent years as the industry has contended with clam-eating predators and warming waters, and 2020 and early 2021 have been especially difficult, industry members said.

Clammers feeling the pinch as green crabs threaten another harvest

May 22, 2017 — Clammers face a shrinking harvest again this year after predator green crabs survived the mild winter, but one scientist may have an answer – aquaculture.

The second mild winter in a row means Maine’s tidal flats will likely be overrun by large, ravenous invasive green crabs this summer.

That’s bad news for the state’s already weakened soft-shell clam industry. One green crab can consume 40 half-inch clams a day and will dig 6 inches to find clams to eat. In 2016, clam landings fell 21 percent, from 9.3 million to 7.3 million pounds, the lowest total reported since 1991, according to the state Department of Marine Resources.

Some of the landings decline was undoubtedly a result of an unusual bloom of toxic algae that forced a monthlong shellfishing ban along about a third of Maine’s coastline last fall. But researcher Sara Randall of the Downeast Institute in Beals notes that a review of clam landings in towns with traditionally high numbers south of the Deer Isle-Stonington closure line found that 19 out of 24 towns, or 79 percent, had harvested fewer clams.

For example, from 2015 to 2016, landings fell 35 percent in Harpswell, 87 percent in Yarmouth and 21 percent in Scarborough. In Freeport, a town on the front line of the effort to combat the green crab invasion, landings decreased 17 percent despite efforts by municipal officials, clammers and researchers like Randall, among others, to use protective measures such as nets and other tools to ward off the green crabs.

The mild winter may only make matters worse. Clammers had hoped for a cold winter so the deep freeze and ice would kill off a lot of the crabs, allowing the clam seed still found in high numbers in Maine waters a chance to settle in the tidal flats and grow, forming those telltale tiny holes that tell clammers a harvest awaits them under the mud.
