Saving Seafood

Aquarium program offers food for thought on eating sustainably

May 4, 2016 — For decades, the National Aquarium has entertained millions of visitors while also teaching them about the need to conserve aquatic resources. The Baltimore institution has rescued marine animals off the coast of Ocean City, built floating wetlands to help clean the Inner Harbor’s water and featured Chesapeake Bay creatures in its tanks and exhibits.

But the aquarium was nearly silent on the subject of seafood consumption. The dark, serpentine halls told the story of precious resources being overfished. But that story didn’t have an ending — a solution for how to stem the decline. It had no programs to guide visitors on where to buy local fish caught sustainably, or how a customer could even understand what that meant.

That’s starting to change. A year ago, the aquarium hired its first director of sustainable seafood: T. J. Tate, who built a sustainable seafood program in the Gulf of Mexico. Tate is bringing together chefs, watermen and others in the seafood industry to talk about catching, raising, buying and eating locally caught fish, crustaceans and shellfish.

It is increasingly part of the story told by aquariums everywhere, at a time when overfishing is rampant worldwide while customers often overlook local products. Even fish that customers think is sustainable comes from far away — farm-raised salmon from Norway, or wild varieties from Alaska — and those distances have ramifications for air and water quality, too.  Visitors often ask what they should eat, and the aquarium wanted to find an engaging way to guide them.

“Telling the local seafood story in an integrated fashion — I mean the sustainable aquaculture supply and wild supply — is one of the most important things we can do to get people connected to oceans and the Bay,” said Eric Schwaab, who hired Tate when he was chief conservation officer at the aquarium. “There’s no better place to do that than Baltimore.”

Research supports blaming warmer waters for lobster decline

May 2, 2016 — HARTFORD, Conn. — Connecticut researchers found no pesticides in lobsters collected in Long Island Sound in late 2014, a new study has found, boosting evidence that warming water temperatures are the main culprit in a huge crustacean decline that has decimated the local lobster industry.

The findings raise questions about restrictions Connecticut passed in 2013, amid concern over declining lobster stocks, limiting coastal use of pesticides that can control mosquito populations that transmit diseases, including the West Nile and Zika viruses.

Lobstermen supported the restrictions, believing pesticides contributed to lobster die-offs. Some municipal and environmental officials were opposed, saying the rules would restrict the use of effective mosquito-controlling pesticides that can protect public health and there was no proven connection between pesticides and lobster die-offs.

The renewed debate about pesticides and lobsters comes as concern grows about the Zika virus spreading to the U.S. from Latin America and the Caribbean. The virus is mainly spread through mosquito bites and causes mild illness or no symptoms in most people. But it can cause microcephaly, a severe birth defect in which babies are born with abnormally small heads.

Ocean acidification poses threat to lobsters

December 18, 2015 — PROVIDENCE — Lobsters are already slowly moving out of southern New England as waters warm, but the iconic crustacean faces another future threat as the climate changes.

As oceans absorb more carbon and become increasingly acidic, juvenile lobsters likely will have a harder time growing and forming strong shells to protect them from predators, according to a recent University of Rhode Island study.

“I’m not sure yet what the mechanism is that is affecting their growth,” URI doctoral student Erin McLean, who led the research, said. “But it takes energy for them to regulate the increased acidity, which is energy they cannot then put toward growth.”

And it’s not just lobsters that could be harmed by the oceans’ changing pH levels. Shellfish populations in Rhode Island and Massachusetts in general are among the most vulnerable in the United States to ocean acidification, according to a recent study in the journal Nature Climate Change.

The study identified the two states among 15 at-risk areas in the nation because colder, northern waters, such as Narragansett Bay, Buzzards Bay and Nantucket Sound, are absorbing more carbon dioxide from the atmosphere and acidifying faster than warmer waters.

Other more localized factors are also playing a part, including nutrient pollution from fertilizers and sewage systems that can add more carbon to the water and the flow of fresh water from poorly buffered rivers, such as the Blackstone in Rhode Island or the many waterways that drain into the Gulf of Maine, which lack minerals to mitigate the effects of acid. Shallow coastal waters also are more susceptible to changes in the ocean’s chemistry.

About a quarter of all carbon emissions from power plants, cars and other sources are absorbed by the oceans, making them more acidic and reducing carbonate levels. Shellfish use carbonates to make their shells, and when fewer of the compounds are available, organisms must expend more energy to build shells and less on eating and survival, researchers say.

CALIFORNIA: No claws for fishermen this Christmas

December 23, 2015 — Most days at around 7 in the morning you can find local fishermen at Ketch Joanne’s Restaurant and Harbor Bar. They come to catch up over coffee.

The turnout varies from day to day along with the topics: Politics, local events and personal stories are all fair game. There is one conversation the group would prefer to leave alone and it involves a particular crustacean struck with a naturally occurring neurotoxin that is keeping it off Christmas dinner plates.

“We’ve got a group of guys being optimistic, thinking it’s going to open soon,” said longtime salmon and crab fisherman Jim Anderson, in reference to the Dungeness crab season. And then there are others, Anderson explained, who are more involved and believe this could be a much lengthier process.

“People are kind of edgy,” Anderson said. “Conversations have gotten away from crab.”

On a recent morning, a group of fishermen crowded around the table nearest to the restaurant’s front door. Sometimes they can fit 11 or 12 guys into the little booth, they say. Often, another group of the younger fishermen will set up at another table.
