Horseshoe Crab Board Accepts ARM Framework Revision and Peer Review for Management Use and Initiates Draft Addendum to Consider Changes to Delaware Bay Management

January 27, 2022 — The following was released by the Atlantic States Marine Fisheries Commission:

The Atlantic States Marine Fisheries Commission’s Horseshoe Crab Management Board reviewed and accepted for management use the 2021 Revision of the Adaptive Resource Management (ARM) Framework and the independent peer review of the Revision. The ARM Revision addresses previous peer review critiques, includes new sources of data, and adopts new modeling software to set harvest levels for Delaware Bay-origin horseshoe crabs that account for the forage needs of migratory shorebirds. The independent peer review panel endorsed the ARM Revision as the best and most current scientific information for the management of horseshoe crabs in the Delaware Bay Region.

“On behalf of the Board, I want to applaud the members of the ARM Subcommittee for their exceptional work on the 2021 ARM Revision,” stated Board Chair Joe Cimino from New Jersey. “This revision made a notable advancement in considering more sources of data and providing a thorough picture of the population dynamics in the Delaware Bay Region. The Board recognizes that there is considerable public concern about the potential impact of the ARM Revision on the status of the endangered red knot and is committed to fully vetting its possible use in setting harvest levels for horseshoe crabs of Delaware Bay-origin through our public comment process.”

Since 2013, horseshoe crabs in the Delaware Bay Region (New Jersey, Delaware, Maryland, and Virginia) have been managed under the ARM Framework to set harvest levels with consideration of the needs of migratory shorebirds. The ARM was developed jointly by the Commission, U.S. Fish and Wildlife Service, and U.S. Geological Survey in recognition of the importance of horseshoe crab eggs to migratory shorebirds stopping over in the Delaware Bay region. In particular, horseshoe crab eggs are a critical food source for the rufa red knot, which is listed as threatened under the Endangered Species Act. In the past decade, more data has been collected on red knots and horseshoe crabs and modeling software has advanced. Thus, the ARM Subcommittee was tasked with revising the ARM Framework to address critiques from the previous peer review panel, include newly available data, and transition to new modeling software since the old software is obsolete.

Several improvements to the ARM Framework were made during this revision. In the original ARM Framework, the population models for horseshoe crabs and red knots were largely based on life history information taken from the literature that was not always specific to Delaware Bay. The ARM Revision improves the models for both species by incorporating region-specific data collected over the past few decades. Additionally, the ARM Revision incorporates more sources of horseshoe crab removals than the previous version, including mortality due to the biomedical industry and commercial discards from other fisheries.

In the original ARM Framework, the Virginia Tech Trawl Survey was used annually to estimate the Delaware Bay horseshoe crab population. The revised ARM Framework still relies heavily on the Virginia Tech Trawl Survey, but also includes additional abundance indices from the region. The population model in the ARM Revision indicated that adult abundance in the Delaware Bay was stable from 2003‐2013 and then began increasing in the past few years for both sexes. This finding is consistent with stock rebuilding due to a period of significantly reduced commercial landings and tight management controls on the fishery beginning in the 2000s in this Region. In 2019, the ARM Revision estimates there were 21.9 million male and 9.4 million female horseshoe crabs in the Delaware Bay Region. Mark-resight and count data from New Jersey and Delaware were used to estimate the population of red knots passing through the Delaware Bay. The passage population estimates were fairly stable between 2011 and 2020 at approximately 45,000 birds and their annual survival estimates were consistently high.  A more detailed overview of the 2021 ARM Revision can be found here.

Using estimated numbers of horseshoe crabs and red knots, the ARM Framework recommends the level of horseshoe crab harvest for the next fishing season. The maximum number of male and female horseshoe crabs the ARM Revision can recommend remains the same at 210,000 females and 500,000 males. While additional data and model improvements are used in the ARM Revision, the conceptual model of horseshoe crab abundance influencing red knot survival and reproduction remains intact with the intent of ensuring the abundance of horseshoe crabs does not become a limiting factor in the population growth of red knots.

After accepting the ARM Revision and Peer Review for management use, the Board initiated a Draft Addendum to consider allowing its use in setting annual specifications for horseshoe crabs of Delaware Bay-origin. The Horseshoe Crab Plan Development Team, composed of representatives from the states and federal agencies, will draft management options for Board review prior to the Board considering approving the document for public comment. If approved, the draft addendum will be released for public comment with opportunities to submit comment through public hearings and written comments. Following the public comment period, the Board will meet to review submitted comment and consider final action on the addendum.

A more detailed overview of the 2021 ARM Revision can be found athttp://www.asmfc.org/uploads/file/61f2f18aHSC_ARM_RevisionOverview_Jan2022.pdf. The final ARM Revision and Peer Review Report will be available on the Commission website, www.asmfc.org, on the Horseshoe Crab webpage under stock assessment reports in early February.

Do River Channels Always Change When Dams Are Removed? It Depends

September 8, 2020 — The following was released by NOAA Fisheries:

Dams are constructed for many purposes, including energy generation, water supply, flood control, and recreation. Dams can also impact the environment, both when they’re built and again when they’re removed. Researchers from the University of Maine, U.S. Geological Survey, and NOAA collaborated to determine what happens to the shape of rivers when a dam is removed. They found that the changes can be minimal under specific geologic and site conditions.

Federal Shutdown Halts Some Environmental Conservation Efforts, Slows Others

January 9, 2019 — Federal researchers in western Massachusetts study ways to protect migrating fish, backyard birds and urban trees. The government shutdown is keeping them home and away from their research.

The researchers work for agencies like the USDA Forest Service and the U.S. Geological Survey.

Curt Griffin heads the UMass Amherst Department of Environmental Conservation, where some of the scientists are based.

“It’s a very, very unfortunate event that our federal colleagues are caught up in this mess,” Griffin said. “And it’s not fair to them. It’s not fair to the public that they provide important services to. So it’s just a very broken system, and they’re caught in the middle.”

Trump Administration Wants to Cut Budget for NOAA, But Congress Unlikely to Accept

February 20, 2018 — SEAFOOD NEWS — Seafood News Editor’s Note: The story below lays out known facts about the cuts to the federal budget made by the Trump Administration. However, it is unlikely that Congress will accept these cuts.

The Trump Administration’s $4.4 trillion federal budget for next year takes some mean whacks to programs that affect fisheries.

Off the top, the spending plan unveiled on February 12 cuts the budget for the National Oceanic and Atmospheric Administration (NOAA) by 20 percent to $4.6 billion. Among other things, NOAA manages the nation’s fisheries in waters from three to 200 miles offshore, which produce the bulk of Alaska’s seafood landings.

It’s the cuts within the cuts that reveal the most.

NOAA Fisheries is facing a $110.4 million drop to $837.3 million, a 14 percent budget cut. That includes a $17.7 million decrease in fisheries science and management, a $5 million cut in data collection needed for stock assessments, a $5.1 million reduction in funding for catch share programs and a $2.9 million cut to cooperative research programs.

The proposals for NOAA law enforcement are even more severe – a decline of $17.8 million is a 25 percent budget reduction.

“The entire law enforcement reduction is coming from the agency’s cooperative enforcement program and will eliminate funding for joint enforcement agreements with law enforcement partners from 28 states and U.S. territories,” reported the Gloucester Times.

The National Weather Service, also under NOAA’s umbrella, is facing a $75 million slice off its $1 billion budget. It will axe 355 jobs, more than a quarter of the NWS staff, including 248 forecasters.

Trump also wants to cut $4.8 million from habitat and conservation programs, wiping out funding and grants for NOAA’s fisheries habitat restoration projects.

The Trump plan proposes gutting $40 million from NOAA climate change programs, which would eliminate competitive grants for research and end studies on global warming in the Arctic, including predictions of sea-ice and fisheries in a changing climate.

The national Sea Grant College Program, which conducts research, training and education at more than 30 U.S. universities, is again on the chopping block.

Funding for programs under the U.S. Geological Survey (USGS) that monitor earthquakes and volcanoes would each drop by 21 percent. The USGS water-resources program, which includes the national stream-gauge network, would be reduced 23 percent.

Trump proposes to cut the Environmental Protection Agency’s budget to $6.1 billion in 2019, its lowest level since the early 1990s and about 25 percent below the current mark.

The EPA budget also eliminates funding for climate-change research while providing $502 million for fossil energy research, an increase of nearly 24 percent.

Seafood sales also could be badly hurt by proposed deep cuts to food stamps, or Supplemental Nutrition Assistance Program (SNAP). Instead of shopping at grocery stores, under Trump’s plan recipients would receive boxes of shelf-stable commodity items such as powdered milk, juices, pasta, peanut butter, and canned meats, fruits and vegetables.

“Seafood is the only major food group that is not considered a USDA commodity. If the new food delivery platform is going to put an emphasis on commodity goods, then that will leave out lean, heart-healthy seafood,” said Linda Cornish, president of the Seafood Nutrition Partnership.

Closer to home, Trump also plans to stop federal funding for the Denali Commission, introduced by Congress in 1998 as an independent agency to provide critical utilities, infrastructure and economic support throughout Alaska.  The plan calls for a $10 million cut out of $17 million, with the difference going to an “orderly closure.”

The White House says that any state that can afford to pay its residents an annual dividend doesn’t need a “unique and additional federal subsidy” such as the commission, wrote longtime Alaska journalist Dermot Cole. Trump added that “the commissions’ effectiveness at improving overall economic conditions remains unproven.”

The FY19 budget, which goes into effect on October 1, now goes before Congress.

Chesapeake Bay sees ‘near-record high’ water quality

December 18, 2017 — EASTON, Md. — Water quality in the Chesapeake Bay has reached a near-record high, according to estimates announced Thursday, Dec. 14, by the Chesapeake Bay Program.

According to preliminary data from the U.S. Geological Survey, almost 40 percent of the Bay and its tidal tributaries met clean water standards for clarity, oxygen and algae growth between 2014 and 2016, which represents a 2 percent increase from the previous assessment period, according to the Chesapeake Bay Program.

Scientists are reasoning it is due in large part to a rise in dissolved oxygen in the deep channel of the Bay.

“The improving trends in water quality standards attainment follow similar trends in other indicators that we track. The acreage of underwater grasses has increased to more than 50 percent of its goal,” Chesapeake Bay Program Director Nick DiPasquale said.

“In addition, we are seeing an increase in the diversity of grass species and the density of grass beds. We also are witnessing improvements in several fisheries, including blue crabs, oysters and rockfish,” DiPasquale said. “While these improving trends are encouraging, we must ramp up our efforts to implement pollution control measures to ensure progress toward 100 percent of the water quality standards is achieved throughout the Bay and its tidal waters.”

SHAWN REGAN: Property Rights Help Environmentalists Protect Wildlife

August 7, 2017 — Earlier this year, President Donald Trump announced that his administration would seek to open oil and gas drilling in the Arctic National Wildlife Refuge. The plan, outlined in Trump’s 2018 budget resolution, has reignited a long-standing debate over the oil-rich Alaskan wildlife refuge.

“Some places are so special that they should simply be off-limits,” Nicole Whittington-Evans of the Wilderness Society said at the time, arguing that the refuge is “too wild to drill” and “has values far beyond whatever oil might lie beneath it.” David Yarnold, president of the Audubon Society, said that drilling in ANWR “would cause irreversible damage to birds and one of the wildest places we have left on Earth.”

Drilling proponents cite the area’s immense energy potential. More than 10 billion barrels of oil could be tapped by developing just a small portion of the 19-million-acre refuge, according to the U.S. Geological Survey – enough to produce 1.45 million barrels per day, more than the United States imports daily from Saudi Arabia. The Trump administration claims that opening ANWR for leasing would reduce the federal deficit by $1.8 billion over the next decade.

How are these conflicting environmental and natural-resource values to be resolved? In the case of ANWR, the answer is politics. The refuge is federal land, so decisions about its management are political by their nature. Debates are often characterized as all-or-nothing decisions – either “save the Arctic” or “drill baby drill” – and when one side “wins,” another side loses.

But what would happen if ANWR were privately owned, perhaps by an environmental group?

NOAA, USGS and partners predict third largest Gulf of Mexico summer ‘dead zone’ ever

June 20, 2017 — Federal scientists forecast that this summer’s Gulf of Mexico dead zone – an area of low to no oxygen that can kill fish and other marine life – will be approximately 8,185 square miles, or about the size of New Jersey.

This would be the third largest dead zone recorded since monitoring began 32 years ago – the average Gulf dead zone since then has been 5,309 square miles.

The Gulf’s hypoxic (low oxygen) and anoxic (oxygen-free) zones are caused by excess nutrient pollution, primarily from human activities such as agriculture and wastewater. The excess nutrients stimulate an overgrowth of algae, which then sinks and decomposes in the water. The resulting low oxygen levels are insufficient to support most marine life and habitats in near-bottom waters, threatening the Gulf’s fisheries.

The Gulf dead zone may also slow shrimp growth, leading to fewer large shrimp, according to a NOAA-funded study led by Duke University. This could mean higher costs of large shrimp at the marketplace and an economic ripple effect on the Gulf shrimp fisheries.

“The Gulf’s summer hypoxic zone continues to put important habitats and valuable fisheries under intense stress,” said Rob Magnien, director of NOAA’s Center for Sponsored Coastal Ocean Research. “Although there is some progress in reducing nutrients, the effects of the dead zone may further threaten the region’s coastal economies if current levels remain.”

This NOAA-sponsored forecast is based on nutrient runoff and river discharge data from the U.S. Geological Survey. The forecast assumes typical weather conditions, and the actual dead zone could be disrupted by hurricanes and tropical storms.

This year’s predicted large size is due mainly to heavy May stream flows, which were about 34 percent above the long-term average and had higher-than-average nutrient loads. The USGS estimates that 165,000 metric tons of nitrate – about 2,800 train cars of fertilizer – and 22,600 metric tons of phosphorus flowed down the Mississippi and Atchafalaya rivers into the Gulf of Mexico in May.

MAINE: Taking Down Dams and Letting the Fish Flow

October 24, 2016 — BANGOR, Maine — Joseph Zydlewski, a research biologist with the Maine Cooperative Fish and Wildlife Research Unit of the United States Geological Survey, drifted in a boat on the Penobscot River, listening to a crackling radio receiver. The staccato clicks told him that one of the shad that his team had outfitted with a transmitter was swimming somewhere below.

Shad, alewives, blueback herring and other migratory fish once were plentiful on the Penobscot. “Seven thousand shad and one hundred barrels of alewives were taken at one haul of the seine,” in May 1827, according to one historian.

Three enormous dams erected in the Penobscot, starting in the 1830s, changed all that, preventing migratory fish from reaching their breeding grounds. The populations all but collapsed.

But two of the dams were razed in 2012 and 2013, and since then, fish have been rushing back into the Penobscot, Maine’s largest river.

“Now all of a sudden you are pulling the cork plug and giving shad access to a truckload of good habitat,” Dr. Zydlewski said. Nearly 8,000 shad have swum upstream this year — and it’s not just shad.

More than 500 Atlantic salmon have made the trip, along with nearly two million alewives, countless baby eels, thousands of mature sea lamprey and dozens of white perch and brook trout. Striped bass are feeding a dozen miles above Bangor in waters closed to them for more than a century.

Nationwide, dam removals are gaining traction. Four dams are slated for removal from the Klamath River alone in California and Oregon by 2020.

Just a few of these removals have occurred on such large rivers, which play an outsize role in coastal ecosystems. But the lessons are the same everywhere: Unplug the rivers, and the fish will return.

A Fish’s-Eye View Of The New England Drought

October 11, 2016 — Just as they do every fall, Massachusetts Fisheries and Wildlife workers are stocking dozens of rivers and ponds with rainbow trout, raised in hatcheries, for anglers to catch.

But this year, because of the drought, a few places won’t get fish. And  some anglers are choosing not to go after wild fish—to give them a break.

According to the U.S. Drought Monitor, most of western Massachusetts is in a severe or even extreme drought.  Stream flows are “much below normal” in most of the state, according to the U.S. Geological Survey. That’s tough on fish.

Brian Keleher, a fisheries manager with the Massachusetts Division of Fisheries and Wildlife, took me to the eastern bank of Dufresne Pond in Granby, where lily pads are splayed out over mud flats.

“I really don’t think there would be anything of any size at least over here,” Keleher said.

There are small pools, but they’re not a great place for fish trying to hide from predators, like birds.

“Fish can be trapped and exposed,” explained Keleher. “They have no where to go, no where to escape. They can’t escape to the depths.”

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.”
