Menhaden Fishery Managers Won’t Pursue Punishment for Virginia

February 11, 2019 — Virginia’s menhaden fishery gets a major victory, as Atlantic fisheries managers decide not to hold the Commonwealth out of compliance with its most recent catch limits.

Back in fall of 2017, the Atlantic States Marine Fisheries Commission (ASMFC) voted to reduce the maximum allowable harvest on the Chesapeake Bay from 87,216 metric tons to 51,000 metric tons a year.

Virginia’s legislature failed to adopt the reduced catch limits, after the East Coast menhaden fishery’s biggest player, Omega Protein, argued the reduction was unnecessary. Under law, the U.S. Department of Commerce can put an immediate moratorium on a state that doesn’t comply with catch limits.

ASMFC won’t seek a moratorium from the Department of Commerce, announcing it has “indefinitely postponed” action to find Virginia out of compliance. ASMFC explains, the Virginia fishery has stayed within the limits of a precautionary “Bay Cap” that was imposed to protect the small, oily fish as an important link in the Chesapeake Bay food chain.

In a statement, ASMFC writes, “This action is contingent upon the Chesapeake Bay reduction fishery not exceeding the cap. If the cap is exceeded, the Board can reconsider the issue of compliance. In making its decision, the Board took into account the fact that reduction fishery harvest within the Chesapeake Bay has been below the cap level since 2012, including 2018 harvest. “

Striped bass population in trouble, new study finds

February 8, 2019 — Striped bass, one of the most prized species in the Chesapeake Bay and along the Atlantic Coast, are being overfished according to a new assessment of the stock’s health — a finding that will likely trigger catch reductions for a species long touted as a fisheries management success.

The bleak preliminary findings of the assessment were presented to the Atlantic States Marine Fisheries Commission, a panel of fisheries managers, on Wednesday. The full analysis was not available. Its completion was delayed by the partial government shutdown, which sidelined biologists in the National Marine Fisheries Service who were working to complete the report.

But, noted Mike Armstrong of the Massachusetts Division of Marine Fisheries, who also chairs the ASMFC’s Striped Bass Management Board, the final results “will likely be the same when [the report] comes out.”

The board asked its technical advisers to estimate the level of catch reductions needed to bring the stock above management targets at its May meeting, when the stock assessment is expected to be ready for approval.

“We know it is going to be pretty drastic,” said John Clark of the Delaware Division of Fish and Wildlife, a member of the board.

The findings of the assessment were a bit of a surprise. Though the overall population was known to be declining, striped bass are often considered a signature success for fishery management.

The overharvest of striped bass, also called rockfish, sent their population to critically low levels in the early 1980s, eventually leading to a catch moratorium. The population rebounded, allowing catches to resume, and by 1997 the population recovered to an estimated 419 million fish aged one year or more.

ASMFC Indefinitely Postpones Action on VA Compliance with Atlantic Menhaden Amendment 3 Chesapeake Bay Reduction Fishery Cap

February 7, 2019 — The following was released by the Atlantic States Marine Fisheries Commission:

The Commission’s Atlantic Menhaden Management Board postponed indefinitely action to find the Commonwealth of Virginia out of compliance with the provisions of Amendment 3 to the Fishery Management Plan for Atlantic Menhaden, specifically the Commonwealth’s failure to implement the Chesapeake Bay reduction fishery cap of 51,000 mt. This action is contingent upon the Chesapeake Bay reduction fishery not exceeding the cap. If the cap is exceeded, the Board can reconsider the issue of compliance.

In making its decision, the Board took into account the fact that reduction fishery harvest within the Chesapeake Bay has been below the cap level since 2012, including 2018 harvest. During its deliberations, the Board commended Virginia Commissioners on their efforts to monitor landings and work with the Commonwealth’s General Assembly to seek full implementation of the provisions of Amendment 3. While the Bay cap was established as a precautionary measure given the importance of menhaden as a prey species, additional information stemming from the development of ecological-based reference points (ERPs) may be informative to the Bay cap issue. Accordingly, the Board will consider action to modify the Bay cap after it completes action on ERPs, anticipated for 2020.

VIRGINIA: Watermen get say on how to tackle ‘ghost pots’ in the Chesapeake Bay

January 29, 2019 — “Ghost pots” remain a menace in the Chesapeake Bay, but how big a menace and what to do about them is anybody’s guess.

That could change now that the 1,056 hard crab fishermen licensed in Virginia are getting a chance to have their say.

Researchers at the Virginia Institute of Marine Science are mailing surveys to watermen asking for their ideas on the countless crab pots that, for any number of reasons, end up haunting the bay, trapping and killing crabs and other hapless creatures that crawl or swim inside.

“This is really to try to find out, what do the watermen want, what do they think,” said Jim DelBene, the VIMS graduate student who developed the Derelict Blue Crab Pot Survey.

In doing so, he researched what other states with blue crab fisheries, from Connecticut through Texas, are doing to reduce ghost pots. He sought out experts at VIMS and at the Virginia Marine Resources Commission and held focus groups for commercial watermen to help choose and frame the survey questions.

Oyster farming bills brewing in Virginia, Maryland legislatures

January 10, 2019 — Jockeying has already begun in Virginia over legislation to determine the fate of the state’s coal ash pits, and new oyster-related measures are in the works in both Maryland and Virginia as the two states’ lawmakers begin their annual legislative sessions today.

In Virginia, Gov. Ralph Northam last week declared his support of legislation that would require coal ash produced by the state’s power plants to be removed from unlined pits and either recycled or deposited in safer, lined landfills.

The byproduct of coal-fired electricity generation, the ash is laced with heavy metals and has been linked to cancer, respiratory problems and other illnesses. An estimated 30 million tons are being stored at sites near Chesapeake Bay tributaries.

Dominion Energy, which owns the sites, estimates that such a cleanup would cost billions of dollars. The Richmond-based company has long advocated leaving the ash where it is, capping it with a layer of soil and a synthetic liner. Legislators have delayed that plan for the last two years, though, amid opposition from environmental groups.

Chesapeake Bay health worsened in 2018 for the first time in a decade, report says

January 9, 2019 — For the first time in a decade, the overall health of the Chesapeake Bay declined, dropping from a C- to a D+ in an annual State of the Bay report issued Monday.

Culprits in the decline include increased runoff from rainstorms in 2018 that were rendered more intense by a changing climate and continued failure in some jurisdictions to curb nutrient and sediment loads.

This is especially true in Pennsylvania, which consistently fails to meet most of its bay cleanup commitments, and where the chronically polluted Susquehanna River delivers half the bay’s freshwater.

“Simply put, the bay suffered a massive assault in 2018,” Will Baker, president of the Chesapeake Bay Foundation, told reporters. “The bay’s sustained improvement was reversed in 2018, exposing just how fragile the recovery is.”

Adding to the assault, Baker said, are plans by the Trump administration to roll back clean water and clean air regulations that will directly impact the watershed.

Trump plans to overturn an Obama-era rule and reduce federal oversight for vast sections of the nation’s waterways and wetlands, and also ease federal restrictions for coal-fired power plant emissions. About a third of the nitrogen that reaches the bay comes from airborne sources, said Baker, some from as far away as the Midwest.

For decades, scientists thought sturgeon had vanished from Maryland waters. They’re delighted to be wrong

January 3, 2019 — When David Secor started his career at the Chesapeake Biological Laboratory almost three decades ago, one of his first projects concluded that the Atlantic sturgeon had all but disappeared from polluted Maryland waters.

The population of the massive fish — often 14 feet long — that once swam with dinosaurs plummeted in the 1900s amid rising demand for their eggs, better known as caviar. Overfishing devastated the species for the same reason caviar is such an expensive delicacy: Sturgeon roe is scarce because females don’t produce it until they’re at least 9 or 10 years old. Even then, the fish don’t spawn every year.

So Secor and other biologists were shocked and then intrigued when, over the past decade, watermen and recreational fishermen started spotting what looked unmistakably like sturgeon flopping and splashing around the Nanticoke River on Maryland’s Eastern Shore. One even landed on the deck of a fisherman’s boat.

URI and VIMS Researchers Show Aquaculture Oysters Can Limit Spread of Dermo in Wild Oysters

December 19, 2018 — SEAFOOD NEWS — Recent research carried out at the University of Rhode Island and the Virginia Institute of Marine Science has found that growing farmed oysters can reduce disease loads in wild oysters.

This counter-intuitive finding is based on the fact that the primary killer of wild oysters is Dermo, a parasite that occurs naturally in the environment, and lives in the tissue of oysters.  The single celled parasite is harmless to humans, and has nothing to do with bacteria such as vibrio.

“The very act of aquaculture has positive effects on wild populations of oysters,” said Tal Ben-Horin, a postdoctoral fellow at the URI Department of Fisheries, Animal and Veterinary Sciences in the College of the Environment and Life Sciences. “The established way of thinking is that disease spreads from aquaculture, but in fact aquaculture may limit disease in nearby wild populations.”

Working with colleagues at the University of Maryland Baltimore County, Rutgers University, the U.S. Department of Agriculture, and the Virginia Institute of Marine Science, Ben-Horin integrated data from previous studies into mathematical models to examine the interactions between farmed oysters, wild oysters and the common oyster disease Dermo.

Basically, Dermo is spread through an oyster reef when infected oysters die, and their tissues decay.  But aquaculture, particularly caged or bagged oysters off the seabed, act as filters, and take in the Dermo parasite, but they are harvested and sold before the parasite has any lethal effects.

The net result is that near oyster farms, the incidence of wild Dermo goes down.

According to Ben-Horin, diseases are among the primary limiting factors in wild oyster populations. There are few wild populations of oysters in New England because of Dermo and other diseases, and in the Chesapeake Bay and Delaware Bay, wild oysters are managed with the understanding that most will die from disease.

“As long as aquaculture farmers harvest their product before the disease peaks, then they have a positive effect on wild populations,” Ben-Horin said. “But if they’re left in the water too long, the positive effect turns negative.”

The study’s findings have several implications for the management of wild and farmed oysters. Ben-Horin recommends establishing best management practices for the amount of time oysters remain on farms before harvest. He also suggests that aquaculture managers consider the type of gear – whether farmers hold oysters in cages and bags or directly on the seabed – when siting new oyster aquaculture operations near wild oyster populations.

‘Just short of a crisis’: Tensions flare as Virginia halts oyster seed harvest in James

December 17, 2018 — Virginia fishery managers are taking the rare step of halting oyster seed harvests in the lower James River as they seek to protect the baby bivalves from overfishing.

Oyster seeds are wild-grown juvenile oysters, or “spat.” Many oyster farmers working in the Chesapeake Bay and its tributaries depend on regular shipments of fresh seed to replenish their lease areas.

The Virginia Marine Resources Commission expects to temporarily stop the catch before the season’s scheduled closure at the end of the year. Without the action, watermen almost certainly would surpass the fall quota of 40,000 oyster seed bushels taken from the river, officials said.

The commission also agreed to block out-of-state seed transfer permits, effective Oct. 31. Between half and two-thirds of the seeds collected from the James are typically sold to Maryland buyers, according to the commission, which will decide whether purchases can resume in the spring based on fall surveys of the river bottom.

The moves come after the commission cut off last year’s spring harvest — when as many as 80,000 bushels were up for grabs — with about a month left to go. That marked the first time since the cap was enacted in 2011 that the commission called on watermen to hang up their hand tongs.

“Basically, the quota did what it was supposed to do,” said Andrew Button, head of the commission’s oyster conservation and replenishment department. “It’s not really to limit anybody but a way to protect the resource.”
