MAINE: Maine Department of Marine resources halts shellfish harvest due to water contamination

August 7, 2024 — Areas for shellfish harvesting have been closed due to contaminated runoff from recent heavy rainfall.

Maine’s Department of Marine Resources says it’s closed areas of the Freeport-Harpswell coast after rain showers carried animal waste into waters where shellfish feed.

Parts of Scarborough, Brunswick, and Yarmouth are also closed due to waste runoff.

Bryant Lewis at MDMR says that filter feeders like the shellfish in these areas are of special concern when water is contaminated like this.

JACK WHITACRE: When a fish is more than a fillet

FREEPORT, Maine — The expression “Waste not, want not” originated in America. By surveying the best seafood utilization practices around the world, Maine could lead the United States in reviving thrift and increasing profits and sustainability.

Maine lobster has become synonymous with value. But what if there were additional profits waiting to be unlocked in what we currently toss out?

Surprisingly, chitin, a natural polymer found in lobster shells, can be harvested and amassed for high-value agricultural, industrial and medical applications. Chitin from crustacean shells is just one example of 100 percent seafood utilization.

Just like Native Americans used every part of the buffalo, there are now opportunities to fully use seafood and push upward on the value chain. Investing time and resources in the utilization movement could generate new jobs, products and startups in Maine and beyond.

The Center for a Livable Future at Johns Hopkins University estimates that the United States wasted 4.6 million metric tons of edible and inedible seafood from 2009 to 2013. During this same period, the center calculated, at least 1.8 trillion milligrams of fish oil was wasted.

With raw fish oil selling for $9 a pound and fish oil capsules selling for $370 a pound, the raw oil wasted in the United States represents millions of dollars in potential value if worked up to pharmaceutical quality. This is just one example of an opportunity for economic and environmental improvement.

MAINE: Mild winter heats up efforts to protect Casco Bay’s clams

May 2, 2016 — Soft-shell clams are a summer tradition around Casco Bay, both for the tourists and residents who love steamers and for the clam diggers who turn long, backbreaking hours on the mud flats into cold, hard cash.

But an infestation of invasive green crabs ravaged juvenile clam stocks in the past four years, adding to ecological changes, competition for coastal access and other pressures facing the state’s second most valuable fishery. Clam landings in the Casco Bay communities of Freeport, Harpswell and Brunswick, some of the state’s leading clam producers, plummeted to historic lows in 2015, and the scarcity of soft-shell clams contributed to all-time high prices.

While some shellfish managers say clam populations have rebounded thanks to a few cold winters that killed off green crabs, harvesters are anxious that the mild winter this year could produce a resurgence of green crabs and throw the fragile industry into a tailspin.

Those fears have clam diggers and scientists stepping up efforts to defend clam beds with boxes and nets. And they are fueling calls for a sea change in the management of soft-shell clams by leasing clam beds so that clammers can better protect the resource from predators.

Some are sounding alarms that without human intervention, the resource faces total collapse.

“Unfortunately, it doesn’t look like people are just going to be able to go out and dig clams like they have without the protection element,” said Sara Randall, a Freeport researcher working with clammers in that town.

Others worry about an overreaction. Although most agree that active management and conservation efforts will be required in the future, not all believe the industry is facing a doomsday.

“We realize there is a bunch going on, but we don’t see it as the end of wild harvest,” said Darcie Couture, a marine scientist working with Harpswell clammers.
