Saving Seafood

Project aims to boost Louisiana oyster safety and profits

September 9, 2020 — LSU researchers have launched a project that aims to give Louisiana oyster harvesters a way of detecting whether waters contain viruses or bacteria that can cause some people to get sick when they eat the shellfish raw or undercooked.

“This project is meant to decrease the number of people getting sick and also decrease oyster recalls,” civil and environmental engineering professor Zhiqiang Deng said in a news release. “The project will aid in the economic development of Louisiana by reducing costly oyster ground closures and recalls, thereby increasing oyster production.”

One-third to 40% of the oysters harvested in the U.S. come from Louisiana waters, more than any other state. The industry employs about 4,000 people in the state, with an economic impact of $317 million annually, according to the Louisiana Seafood Promotion & Marketing Board.

About a fifth of all oysters harvested in Louisiana come from the Terrebonne Basin, an area that includes all of Terrebonne and parts of Lafourche and several other parishes between the Acthafalaya River and Bayou Lafourche, state figures show.

MARYLAND: Land-based salmon farm proposed for Chesapeake’s Eastern Shore

September 3, 2020 — The Chesapeake Bay is known to many for the seafood it produces: blue crabs, oysters and striped bass.

In a few years, though, the Bay region could become a major producer of an even more popular seafood that doesn’t come from the Chesapeake. A Norwegian company, AquaCon, has unveiled plans to raise salmon on Maryland’s Eastern Shore.

AquaCon executives intend to build a $300 million indoor salmon farm on the outskirts of Federalsburg in Caroline County. By 2024, they aim to harvest 3 million fish a year weighing 14,000 metric tons — an amount on par with Maryland’s annual commercial crab catch.

If that goes as planned, the company expects to build two more land-based salmon farms on the Shore over the next six or seven years, bringing production up to 42,000 tons annually. That’s more than the Baywide landings of any fish or shellfish, except for menhaden, and more valuable commercially.

AquaCon’s announcement comes amid a rush by mostly European aquaculture companies to supply Americans with farmed salmon. Another Norwegian company is preparing for its first full harvest later this year from a facility south of Miami, and plans have been announced to build big indoor salmon farms in Maine and on the West Coast. Two small U.S.-based salmon operations in the Midwest also are moving to expand production.

MAINE: Portland Fish Exchange looks to shore up its future with aquaculture

September 3, 2020 — The Portland Fish Exchange is launching a new oyster sorting and bagging operation inside its cold, cavernous auction warehouse in hopes of growing the state’s aquaculture economy and diversifying a business plan that’s taken a beating since local ground fish landings collapsed.

On Wednesday, the Exchange received the first of what it hopes will be many oyster deliveries. Two employees measured, sorted, bagged and tagged five 100-count bags of Eastern oysters harvested by Running Tide, a two-year-old aquaculture company that operates a hatchery in Harpswell and grows oysters, clams and scallops at three coastal Maine locations.

“Ground fish landings have been going down, down, down for years,” said Bert Jongerden, the longtime general manager of the exchange. “The numbers told us we had to find something else. So we thought, let’s do for aquaculture what we’ve done for ground fishermen. Give them the shoreside support they need to focus on harvesting instead of chasing down sales.”

The pearly white shelled oysters, which measure from 2 ½ inches to 5 inches from hinge to outer shell fan, have rounded edges created from being tumbled, or stirred, to avoid being chipped when shucked, and deep pockets that hint at the plump meat inside. This first harvest is bound for The Shop, a raw bar on Washington Avenue, to be served up on Friday.

Contaminants found in oysters could portend larger environmental and food safety problem

August 10, 2020 — New research suggests contamination of oyster beds with plastics, paint, and baby formula in Asia could reveal a larger emerging global public health risk.

Scientists from the University of California, Irvine, in collaboration with Environmental Defense Fund, Cornell University, and Australia’s University of Queensland, found traces of plastics, kerosene, paint, talc, and milk supplement powders in the beds on the eastern Andaman Sea of Myanmar.

Seafood industry navigates rough waters as debts, inventory rise higher

August 4, 2020 — When it comes to business plans during the coronavirus pandemic, the seafood industry has found itself at sea.

“We don’t have a clue,” said Jure Slabic, an oysterman in Galveston, Texas. “We haven’t processed a single oyster since March 23.”

More than most foodstuffs, the seafood industry depends on restaurants that put a premium on freshness. Consequently, the coronavirus shutdowns slammed fishers, leaving boats at the dock, inventory stacked or tossed as debt piles up.

NOAA: Lobsters will look for cooler water

July 24, 2020 — Cape Cod is known for its lobsters as much as for its oysters and quahogs. But it’s getting too warm in these waters for the tasty crustacean.

Researchers have projected significant changes in the habitat of commercially important American lobster and sea scallops on the Northeast U.S. continental shelf. They used a suite of models to estimate how species will react as waters warm, and it suggests that American lobster will move further offshore and sea scallops will shift to the north in the coming decades, a recent statement from NOAA Fisheries warned.

Findings from the study were published recently in Diversity and Distributions. They pose fishery management challenges as the changes can move stocks into and out of fixed management areas. Habitats within current management areas will also experience changes — some will show species increases, others decreases, and still others no change.

“Changes in stock distribution affect where fish and shellfish can be caught and who has access to them over time,” said Vincent Saba, a fishery biologist in the Ecosystems Dynamics and Assessment Branch at the Northeast Fisheries Science Center and a co-author of the study.

Ocean Acidification Threatens Bivalve Industry

July 9, 2020 — Worldwide, ocean levels are rising at an accelerated pace. Cape May County is feeling the effects of exacerbated weather events, as a result.

Yet, there is another drastic change affecting the oceans – a decrease in the water’s pH levels. This is a change that industry leaders and scientists fear will drastically affect the county, namely its bivalve (aquatic invertebrates with a hinged shell) industry that is, as marine and coastal sustainability expert Dr. Daphne Munroe said, “At the heart of the economy in this region.”

As carbon is released into the atmosphere, it was once speculated that the ocean’s tendency to absorb emissions would be a net positive, as it spared the Earth’s atmosphere from the worst of the emissions. Dr. Feely, senior scientist at National Oceanic and Atmospheric Administration (NOAA), said, “[It’s] a huge service the oceans are doing that significantly reduces global temperature.”

However, scientists are coming to realize that the ocean’s absorption of carbon emissions comes at a great cost, and that the long-term effects of an ocean that has absorbed great amounts of carbon emissions mean that ecosystems will ultimately suffer.

NORTH CAROLINA: Hard-Hit Oyster Growers Ineligible For Aid

June 23, 2020 — Oyster sales in North Carolina and other coastal states throughout the country tanked when restaurants halted dine-in service in March as part of the effort to curb the spread of COVID-19.

“Everyone – East Coast, West Coast – once COVID-19 shut down restaurants pretty much all growers saw their sales drop between 95 and 100%,” said Chris Matteo, East Coast Shellfish Growers Association North Carolina representative. “Restaurants are our primary client. Most high-end and middle-tier restaurants aren’t normally involved in the takeout business. Even the ones that did pivot to takeout, people just generally aren’t comfortable buying or selling raw shellfish for takeout. The market collapsed.”

Oyster farmers are among the ranks of numerous American growers who’ve experienced tremendous crop losses as a result of the pandemic. Yet oysters are not on the U.S. Department of Agriculture’s list of specialty crops, leaving shellfish farmers out of the running to receive federal aid afforded other farmers, including the Coronavirus Food Assistance Program, or CFAP.

Maryland’s wild oyster harvest doubles from last year

June 16, 2020 — Despite having fewer days to work, Maryland watermen harvested nearly twice as many wild oysters last season as they did the previous year, state officials report. Even so, a new study finds the state’s population of bivalves is in much better shape now than it was two years ago, with abundance up and overfishing down.

As a result, state fisheries managers say they’re weighing whether to maintain catch restrictions put in place last season or relax them for the next wild harvest season, which normally begins Oct. 1.

Data presented Monday night to the Department of Natural Resources’ Oyster Advisory Commission indicates that the overall abundance of adult, market-size oysters in Maryland’s portion of the Chesapeake Bay has rebounded considerably since 2018 and is now at the fifth highest level since 1999.

Preliminary figures indicate the wild harvest last season topped 270,000 bushels, a nearly 90% jump from the 145,000 bushels landed in the 2018–19 season.

Oyster Reef Restoration Efforts Could Use Your Help—And Your Oyster Shells

May 28, 2020 — A couple of centuries ago, oysters were ridiculously prevalent in the Chesapeake Bay, which stretches nearly 200 miles from Havre de Grace, Maryland to Virginia Beach, Virginia. At that time, more than 17 million bushels of everyone’s favorite bivalve were pulled from its waters every year, but that number has since dropped by 98 percent due to a depressing combination of overfishing, degradation of their habitats, and water pollution.

But part of the Chesapeake Bay Foundation’s mission to “Save the Bay” includes a number of oyster restoration programs, including small-scale oyster farming and “oyster gardening,” which allows amateur aquaculturists to spend a year caring for baby oysters, which are then transplanted onto protected reefs when they’re a year old. These restored reefs not only help to increase the oyster population, but they also provide food and shelter for a variety of fish and other marine life.

In order for an oyster to live past the larval stage, it has to find a solid object to attach to. Once it’s safely anchored, it can put its energy into feeding itself and growing its own shell. It also happens that the best things that baby oysters—also called spat—can attach themselves to are the discarded shells of other oysters.
