Saving Seafood

Dolphins more common in Potomac than previously thought

July 19, 2016 — A waterfront house on Virginia’s Northern Neck promised to be a getaway for Janet Mann from three decades of studying dolphins, primarily in Australia’s Shark Bay.

But the day after Mann and her husband closed on the place in Ophelia, VA, four years ago, she spied an all-too-familiar sight from the shore where the Potomac River joins the Chesapeake Bay.

“I said, ‘Oh, look, dolphins!’ And then I thought, ‘Oh, no,’” Mann recalled. “I think we’ve given up on getting me away from my work.”

A professor of biology and psychology at Georgetown University in the District of Columbia, Mann has since embraced the Potomac as the next frontier for her research. In fact, she’s turned that riverfront retreat into a field station for observing a surprising number of bottlenose dolphins that venture up the Bay’s second largest tributary every summer.

Though dolphins have been spotted occasionally in the Potomac for at least the last six years, Mann said she hasn’t met anyone outside of those who live near her summer house who realize how many of the marine mammals are visiting on a regular basis. Last year, she and her research team of students and other Georgetown faculty tallied nearly 200 different animals in just a two-week span.

MARYLAND: More sturgeon turn up in Bay, raising new questions – and worry

July 13, 2016 — For years, scientists thought there might not be any native Atlantic sturgeon in the Chesapeake Bay. That idea changed in recent years, as biologists began netting hundreds of adults in the James River, and others began turning up in other tributaries.

Now, genetic analyses show the Chesapeake is home to at least two — and possibly more — distinct populations of the endangered fish.

DNA analysis shows that James River sturgeon and those recently found spawning next door in the Pamunkey River, a tributary of the York River, are not even particularly closely related, despite their geographic proximity.

The 138 Pamunkey fish sampled seem more closely related to what could be a third population farther up, and across, the Bay in the Nanticoke River where 15 adult fish have been caught — and released — the last two years.

It’s too early to say whether the sturgeon netted in the Nanticoke and its tributaries constitute a unique population, said Tim King, a fisheries biologist with the U.S. Geological Survey who did the genetic analysis. King said he would like at least 25–30 samples before offering a more concrete opinion about the Nanticoke sturgeon.

“It is way too early to draw any conclusions,” King said. “But it would seem that they are not James fish. They are genetically more similar to the Pamunkey fish than they are the James, but I am not willing to say that they are Pamunkey fish.”

How to Find Out If the Crabs You’re Eating Are Local

July 5, 2016 — Seafood traceability is a global concern—and the bay isn’t exempt: The crab on Chesapeake menus may come from elsewhere in the country, or might be an entirely different species from Asia. Here are a few tips for determining whether the crab you’re eating is local.

Know your species

Callinectes sapidus, Atlantic blue crab, is harvested from the bay as well as the Carolinas and the Gulf. The usually cheaper Portunus pelagicus, Asian blue swimming crab, is imported. Beware ambiguous descriptors such as “blue crab” (versus “Chesapeake blue crab” or “local blue crab”) and, in preparations like crabcakes, “Chesapeake-style.”

Know your season

Legally, the Chesapeake crab harvest runs from April to mid-December, with the fattest, heaviest crabs typically arriving in late summer/early fall. Those Memorial Day–weekend jumbos? Likely not local.

Long slog ahead for new attempt to move shad past Conowingo, other dams

June 15, 2016 — Leon Senft remembers a time when he and other fishermen lined the shore of the Susquehanna River below the Conowingo Dam and hooked American shad almost as fast as they could cast their lines in the churning water.

“We really had a bonanza there for a while,” recalled Senft, 85, who’s been angling for the big migratory fish longer than most people are alive. “It was not unusual to catch 50–100 a day. My personal best was 175.”

That catch-and-release heyday for Senft was maybe 20 years ago, when American shad appeared to be on the rebound from a severe decline in their springtime spawning runs. Optimism abounded, as a big new fishlift hoisted more and more of them over the 94-foot dam on their way upriver to reproduce.

But the rebound went off the rails. Although the number of American shad getting a lift over Conowingo rose steadily for a decade, it then dropped and kept dropping.

Now, after years of study and negotiations, the U.S. Fish and Wildlife Service and Exelon Corp., Conowingo’s owner, have come up with a new plan for rebuilding the Susquehanna’s runs of American shad and river herring — related species that are even more depleted. In a press release announcing the deal in April, a federal wildlife official called it “a victory for everyone who lives or recreates on the Susquehanna River and the Chesapeake Bay.”

But those close to the situation are still cautious. Given the discouraging track record so far, they say, bringing these fish back will take a sustained effort for decades — if it can be done at all.

“I was around when we did this last time, 25 years ago,” said Bill Goldsborough, senior fisheries scientist for the Chesapeake Bay Foundation. “We thought that was going to do a lot more than it did.”

Virginia Institute of Marine Science deploys ‘Frankenturtles’ in effort to boost species survival

June 14, 2016 — A part of David Kaplan recognizes that his new research into sea turtle mortality is pushing the envelope.

The assistant professor and his graduate student Bianca Santos are doing something never before attempted: repurposing the carcasses of two dead loggerheads, outfitting them with GPS devices and setting them adrift in the Chesapeake Bay, all in the name of science.

“Most people have not had the reaction that this is disgusting,” Kaplan said Monday morning from the boat basin at the Virginia Institute of Marine Science (VIMS) in Gloucester Point.

“It’d be interesting to see what the public thinks, because I think of it as a really great thing. I mean, it’s pretty gruesome, but it’s taking animals that died tragically and reusing them for the (greater) good. A better purpose.”

Chesapeake Bay health improves in 2015

May 18, 2016 — The overall health of Chesapeake Bay improved in 2015, according to scientists at the University of Maryland Center for Environmental Science. The largest estuary in the nation scored a C (53%) in 2015, one of the three highest scores since 1986. Only 1992 and 2002 scored as high or higher, both years of major sustained droughts.

“We’d expect to see improvements after a drought year because nutrients aren’t being washed into the Bay, fueling algae blooms and poor water quality,” said Bill Dennison, Vice President for Science Applications at the University of Maryland Center for Environmental Science. “However, in 2015 stream flow was below normal, but nowhere near the drought conditions in 1992 and 2002. Thus, the high score for 2015 indicates that we’re making progress reducing what’s coming off the land.”

The overall score for the Chesapeake Bay Health Index for 2015 was 53%, compared with 50% in 2014 and 45% in 2013. There were strong improvements in many regions throughout the Bay, such as the Choptank River, Upper Eastern Shore, Lower Western Shore, and the Rappahannock River. There were no regions that had lower scores in 2015 compared to 2014. Improvements could be related to a number of factors, including several years of moderate weather, sewage treatment upgrades, use of winter cover crops by farmers, and reductions in atmospheric nitrogen deposition.

Hatchery Is Breeding Better Oysters To Boost North Carolina Aquaculture

May 16, 2016 — To feed a hungry world, it’s no longer enough to catch wild seafood. Many fisheries are in decline because of overfishing, environmental stresses or both, and human demand for protein has never been greater. That means aquaculture has to be a growing part of the world’s food supply. Here in North Carolina, it’s also an essential component in growing the economies of our coastal communities.

A case in point is the state’s oyster fishery, which once supplied much of the East Coast, but now can’t even meet demand from within North Carolina. Our state is working hard to emulate our neighbors to the north, who through state-sponsored shellfish research hatcheries have bred a better oyster, able to thrive in Chesapeake Bay and other Virginia waters.

In 2011, North Carolina began supporting a hatchery, right here on the CREST Research Park in Wilmington. UNC Wilmington faculty researchers and student workers are using selective breeding techniques, supplemented by some high-tech genetic research, to develop new strains of oysters to suit our state’s waters. The hatchery is also working with scallops, which are more challenging to grow but more lucrative to sell, as well as sunray Venus clams. But oysters are its primary product.

A recent comparison of oyster cultivation in North Carolina and Virginia, conducted by the N.C. Rural Economic Development Center, showed that in 2005, the two states were roughly even, each producing roughly a quarter-million dollars’ worth of farmed oysters. But while Virginia’s production exploded, reaching almost $10 million in just seven years, our state’s aquaculture operations barely doubled their output.

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.”

Susquehanna River: Deal reached on fish, eel passage at Conowingo Dam

May 3, 2016 — Exelon Corp. has pledged in a deal announced last Monday to work to enhance spawning fish passage at Conowingo Dam over the next 50 years, seeking to revive the Susquehanna River’s meager stocks of American shad and river herring.

The Chicago-based company and the U.S. Fish and Wildlife Service said they had reached agreement to improve at least one of two fish lifts at Conowingo and meanwhile start trucking migratory shad and river herring upriver past it and three other dams in Pennsylvania.

The agreement comes after years of negotiations between the company and wildlife agencies and conservation groups, which were seeking to revive the once-legendary spawning runs of shad and herring. The number of returning fish each spring has been trending downward since the 1980s, and wildlife agencies and conservationists wanted Exelon to make potentially costly upgrades to fish lifts there as a condition of renewing its federal license to operate the hydroelectric facility.

The company’s license to operate Conowingo expired in 2014, but the Federal Energy Regulatory Commission has extended the permit while the parties — including Maryland —attempt to hash out their differences. An even more contentious issue involves what Exelon may have to do about the buildup of nutrient-laden sediment in the dam’s reservoir, which studies have shown could complicated efforts to restore the Chesapeake Bay’s water quality.

Alaska’s $10 Million Cut to its Fisheries Budget Expected to Ripple Across the Commercial Industry

April 26, 2016 — SEAFOOD NEWS — The $10 million cut to Alaska’s fishery budget for the 2017 fiscal year is expected to have widespread ramifications for the state’s commercial industry.  Last year’s budget cuts resulted in 109 fishery projects getting axed. Now another 65 are on the cut list for the upcoming fiscal year that begins on July 1. The slimmer budget means resources are more limited for fishery stock surveys and scientific research in addition to other fishery management needs.  “With cuts of that magnitude, everything is on the table,” said Scott Kelley, director of the Commercial Fisheries Division at the Dept. of Fish and Game.

We ran an opinion piece from D.B. Pleschner, the Executive Director of the California Wetfish Producers, that points to the recent scientific evidence that suggests West Coast sardine stocks are actually rebuilding. Pleschner writes how recent recruitment reports show the fishery’s young fish stocks are trending very close to how they looked prior to the 2007 population peak.  She also discusses how these scientific findings have gained little attention from the media and NGOS, who have instead blamed overfishing and lack of management for the stock’s declines.

In other news, China added lobster, crab and coldwater shrimp imports to a list of E-commerce items that are eligible for expedited cross-border clearance and lower taxes. The list an effort by China to reduce the cross-border tax paid by consumers, and to close a loophole that allowed parcel shipments to avoid taxes when resold, for instance, when they are imported by wholesalers.

Vietnam expects a 12 percent hike in exported shrimp revenues to push its overall earnings in seafood shipments past $7 billion this year. Shrimp is on track to account for about half of this year’s earnings.

Finally, Vinh Hoan will debut a line of untreated, premium pangasius fillets to the market at its booth number 5-553 during the Seafood Expo Global in Brussels this week. “People today want more natural food options with minimal processing and our untreated Premium Pangasius fillets provide that along with a delicious dining experience,” said Nguyen Ngo Vi Tam, Vinh Hoan Sales and Marketing Director. “With Vinh Hoan’s long-established commitment to sustainable practices, it just makes sense we would lead the way with this untreated option.”
