Saving Seafood

Trump administration pledges to do more with less for U.S. aquaculture

June 5, 2017 — “Aquaculture is not the future of oyster harvests. It’s the present,” said Mark Luckenbach – Virginia Institute of Marine Science.

Luckenbach, based at the VIMS lab at Wachapreague, told me those words 11 years ago, when I wrote my first story about oyster aquaculture. Since then, I’ve written more than 100 stories on the topic, and someday, I hope, I’ll write a book. One thing is sure: the present has taken a long time to arrive – not just in the Chesapeake Bay, but all over the country.

Eighty to 90 percent of the seafood eaten in the United States is imported, according to the National Oceanic and Atmospheric Administration. In Baltimore, where I live, the crabmeat at my local grocery store is not from the Chesapeake Bay. The salmon is not from this country. And striped bass? Never seen it there, though I live just an hour from where one could catch some of the nicest rockfish you could find anywhere.

NOAA officials want to change what they’re calling a $14 billion seafood trade deficit. At a webinar last week, agency officials said Commerce Secretary Wilbur Ross, who oversees NOAA, is committed to “eliminating barriers” to growing aquaculture here in the United States.

In Maryland, we know well some of these barriers as they relate to growing oysters. Would-be growers have spent years awaiting permission to put oysters in the water, even though the bivalves filter the water, increase biodiversity, and even spur recruitment for the Bay’s long-troubled wild oyster population, which is less than 1 percent of historic levels.

On a conference call during the webinar, federal officials touted Maryland’s permit innovations as a success. (They didn’t mention that oyster farmers have blamed NOAA’s National Marine Fisheries Service for some of those delays, relating to the possible impact of oyster farming on endangered marine turtles.) Maryland worked with the Baltimore District of the U.S. Army Corps of Engineers to streamline the permit process. State and federal officials, as well as oyster farmers, report it is working more smoothly now. (NOAA officials said they had an “ombudsman” role in the process.)

Chesapeake Bay earns ‘C’ for overall health; blue crabs, rockfish, anchovies are thriving

May 9, 2017 — Maryland environmental scientists gave the Chesapeake Bay a “C” for overall health in 2016, with improved fish populations and water conditions contributing to the second-highest grade the ecosystem has received in 30 years of scoring.

The report card released Monday by the University of Maryland Center for Environmental Science showed that the bay is 54 percent of the way toward achieving key health benchmarks, an uptick of one percentage point compared with the previous year.

Experts cited the results as proof that efforts to clean up the estuary are working.

“While only a slight improvement, it’s encouraging that the overall health remained steady despite many pressures on the Chesapeake Bay and across its watershed,” said Bill Dennison, a top scientist with the center.

Sen. Benjamin L. Cardin (D-Md.), speaking at a news conference in Baltimore, called for continued federal support for bay restoration. He noted that President Trump this year proposed slashing funding for Chesapeake Bay cleanup efforts. Congress last month approved a fiscal 2017 budget that maintains funding for the bay at $73 million, the same level as the previous year.

“The long-term investment is working,” Cardin said. “We can’t slow down. . . . It’s critically important to maintain the strong federal role.”

The bay’s highest score on record, 55 percent, occurred in 2002. The Chesapeake earned its lowest score, 36 percent, the following year. The Center for Environmental Science awards an “A” for scores of 80 to 100 percent; “B” for 60 to 79 percent; “C” for 40 to 59 percent; “D” for 20 to 39 percent; and “F” for anything lower than that.

BEN LANDRY: Assertions about menhaden population were a bit fishy

May 1, 2017 — In his recent Bay Journal op-ed, Don’t let menhaden become a case of could have, should have, would have, March 2017, Bill Bartlett claims that menhaden are both scarce and unregulated in the Chesapeake Bay.

Neither assertion is true according to the latest and best science on menhaden. This data instead indicate that this species is being managed sustainably and responsibly.

The late U.S. Sen. Daniel Patrick Moynihan famously stated that everyone is entitled to his own opinion, but not his own facts. Because a column appears in the op-ed section does not excuse it from journalistic obligations of fact-checking and accuracy. Let’s look at the facts along with supporting citations.

Bartlett believes “the [Atlantic States Marine Fisheries Commission] lets people have their say about menhaden and then does nothing or very little” to properly manage the species. This could not be further from the case – the ASMFC bases its very precautionary management decisions on the most up-to-date scientific standards. The evidence points to that management being quite conservative: According to the most recent stock assessment report on Atlantic menhaden, menhaden are not overfished, nor are they experiencing overfishing. The commission deemed the species to be so healthy that the quota was actually increased 10 percent. Analysis from ASMFC experts indicated that the quota could have been increased by as much as 40 percent without the risk of overfishing the stock.

Sonar revealing more river herring in Choptank River than expected

March 31, 2017 — Scientists have a powerful new tool to help them “see” fish in the Chesapeake Bay’s murky tributaries, and it’s yielding some surprisingly good news about two of the estuary’s most troubled species. “Imaging sonar” uses sound to help them view, and count, passing fish in dark or cloudy water. For the past few years, scientists with the Smithsonian Environmental Research Center have been deploying one of these underwater sound cameras in some of the Bay’s rivers to monitor spawning runs of alewife and blueback herring, collectively known as river herring.

No one knows for sure how many river herring are in the Bay, as fisheries managers lack the staff and resources to do a comprehensive assessment. But a SERC-led team of scientists deployed an imaging sonar device in the Choptank River in 2014 that captured images of the fish as they swam by. Based on the rate at which scientists saw the shadowy blips cross their computer screens, they estimated that as many as 1.3 million river herring swam upriver that spring to spawn. That’s more than expected, and way more than state biologists had figured were there in the early 1970s, the last time anyone looked intensively at the Choptank’s herring runs.

MARYLAND: Oyster sanctuary bill finds support in House of Delegates

March 20, 2017 — The House of Delegates voted 102-39 on Thursday in favor of a bill that would keep intact existing oyster sanctuaries on the Chesapeake Bay, a blow to the commercial fishing industry’s efforts to expand the state’s oyster fisheries.

Supporters and opponents of the bill, named the Oyster Management Plan, are both saying that their solution is best for the long-term health of the bay and its oyster population, which helps clean the Chesapeake by filtering nutrients like excess algae out of the water column.

“(The Oyster Management Plan) protects the fragile progress that has been made to date in recovering oyster populations,” the Chesapeake Bay Foundation said in written testimony to the House Environment and Transportation Committee on Feb. 24. “This bill would in no way impact (the Department of Natural Resource’s) ability to manage the public oyster fishery, including the development of rotational harvest management for public oyster bottom.”

VIMS coastal shark study shows species recovering from overfishing

March 6, 2017 — The 1975 horror movie “Jaws,” featuring a giant, man-eating shark, turned the ocean into a scary place for swimmers.

It got even scarier for sharks.

In large part because of that blockbuster and its many sequels, sharks were hunted increasingly by recreational and commercial anglers in the ’70s and ’80s, to the point that some species nearly disappeared.

Now, a new analysis of seven coastal shark populations led by the Virginia Institute of Marine Science in Gloucester Point indicates that federal protections enacted in the 1990s have brought most of those species back from the brink.

ASMFC Atlantic Striped Bass Management Board Initiates Development of Draft Addendum V to Consider Liberalizing Management Measures

February 3, 2017 — The following has been released by the Atlantic States Marine Fisheries Commission:

The Atlantic States Marine Fisheries Commission’s Atlantic Striped Bass Management Board initiated the development of Draft Addendum V to Amendment 6 to the Atlantic Striped Bass Fishery Management Plan (FMP) to consider liberalizing coastwide commercial and recreational regulations. The Board’s action responds to concerns raised by Chesapeake Bay jurisdictions regarding continued economic hardship endured by its stakeholders since the implementation of Addendum IV and information from the 2016 assessment update indicating fishing mortality is below the target. 

Addendum IV, implemented for the 2015 fishing season, required coastwide harvest reductions to reduce fishing mortality (F) to a level at or below the target. Specifically, coastal fisheries implemented measures to reduce harvest by 25% compared to 2013 levels, and Chesapeake Bay fisheries implemented measures to reduce harvest by 20.5% compared to 2012 levels. Additionally, an objective of Addendum IV is to protect the 2011 year class.

According to the results of the 2016 stock assessment update, the Atlantic striped bass stock is not overfished and overfishing is not occurring. Furthermore, Addendum IV successfully reduced fishing mortality to a level below the target (F in 2015 is estimated at 0.16), and length-frequency data from the catch in 2015 indicates a strong presence of the 2011 year class which is anticipated to join the coastal spawning population this year.

A draft of the addendum will be presented for Board review in May. For more information, please contact Max Appelman, Fishery Management Plan Coordinator, at mappelman@asmfc.org or 703.842.0740.

Learning About Menhaden: A Journey to Reedville

January 27, 2017 — The following is excerpted from an article by Emily Liljestrand, a master’s student in the University System of Maryland’s Marine Estuarine Environmental Sciences program. It was published Tuesday by Maryland Sea Grant:

Atlantic menhaden, though completely unpalatable to all but the most desperate diners, can be found in many commercial products. They are processed into omega-3, fatty-acid-rich nutritional supplements as well as aquaculture feed and fertilizer. People have utilized them for hundreds of years. The name “menhaden” even comes from the Native American word “munnawhatteaug,” which means “that which fertilizes.”

To get from this one-foot-long, oily, bug-eyed creature to the myriad of products we use them for requires several steps of fishing and processing. Most of which we got to witness first-hand on our trip to Reedville.

We were welcomed by the Omega Protein staff who guided us to a cozy conference room where we watched a video that demonstrated the fishing operation. Delightful as it might have been, having nine students and faculty go out on a fishing vessel that can often spend days offshore is a bit impractical.

But in the video we got to see the whole fishing process. Spotter planes take off across the Chesapeake Bay and nearshore Atlantic waters, looking for the telltale sign of a menhaden school – darkened bubbling waters where menhaden were being targeted by predatory fish and sea birds. Pilots can estimate with a high degree of accuracy not only the size of a school but also the average size of menhaden within that school.

The fishing vessel charges onto the scene and once in position, deploys two smaller seine boats that together use a single net to rope up as much of the school as they can. Once the bottom “purse string” gets pulled, it’s only a matter of hauling everything up onto the larger vessel and/or vacuuming menhaden into the hold. If done efficiently, the whole process may take no longer than half an hour.

Our guided tour around the on-shore facility in Reedville showed us how the processing continues onshore. The school of menhaden (or multiple schools, collected over several days) are deposited into a large holding vat and cooked at extreme temperatures. This procedure breaks down the fish and creates a sort of menhaden “slurry.” Through a series of heating, cooling, and further chemical processing, the lighter liquid oil gets separated from the harder, denser meal.

Omega Protein told us about its efforts to make its processing operations sustainable. It uses recycled/reclaimed water extracted from the menhaden themselves as a cooling agent, which has saved about 18 million gallons of water annually, and safely disposes of nitrogen byproducts. Omega’s fossil fuel consumption has dropped by 80 percent since 2012 thanks to several plant renovations.

MONTY DEIHL: What The Virginian-Pilot gets wrong about menhaden

January 13, 2017 — THE PILOT gets one thing absolutely right in its Dec. 28 editorial on menhaden management (“Let scientists manage menhaden approach”): Menhaden is important to the Chesapeake Bay, and the species and the fishery that depend on it deserve proper management.

Unfortunately, the editorial’s proposals are based on a flawed and incomplete understanding of menhaden science and management.

The Pilot urges fisheries managers at the Atlantic States Marine Fisheries Commission to adopt ecosystem-based reference points as it considers Amendment 3 to the Menhaden Fishery Management Plan.

While almost everyone supports ecosystem-based management in the long run, no such system is ready to be implemented. The ASMFC’s best fisheries scientists are currently developing new ecological reference points specifically for menhaden, which are expected to be completed in the next few years.

In the meantime, fisheries managers should not reach for unproven, improper management practices when they lack the necessary science to guide the process.

In supporting new reference points, the editorial offers an ill-informed indictment of the current management approach, calling it a “tragedy of the commons.” But the ASMFC’s latest stock assessment found that menhaden fishing mortality is at its lowest level on record — hardly the “tragedy of the commons” that The Pilot suggests.

CHRISTI LINARDICH: Fishing isn’t the problem

January 12, 2017 — “Let scientists manage menhaden approach” (editorial, Dec. 28) perpetuates the belief that so many people seem to have lately — that the largest impact on striped bass populations is lack of menhaden to eat.

According to the Atlantic States Marine Fisheries Commission, menhaden biomass was lowest during the mid-1990s to mid-2000s, but during that time (1993-2004, to be exact) striper recruitment was strong.

This is not easily explained, but neither is the simplified belief that taking a sustainable amount of menhaden out is magically taking striper off the end of people’s fishing lines.

Critics conveniently ignore the fact that the Chesapeake Bay and associated rivers, which striper depend on to complete their reproductive cycle and menhaden rely on for nursery grounds, has been severely altered by humans through dams and pollution.
