Harmful algal blooms can be lethal for humans. Scientists wonder if they cause seabird die-offs, too

July 29, 2021 — Paralytic shellfish poisoning, caused by eating seafood contaminated with toxins from harmful algal blooms, can be deadly to humans. Now, using marine samples from Unalaska, scientists are trying to understand if those harmful algal blooms could also be responsible for seabird die-offs.

There’s not much data on how saxitoxin — a harmful compound produced by algal blooms that cause PSP — spreads through the larger food web. But in July, a group of biologists with the United States Geological Survey visited Unalaska to collect samples of plants and animals in hopes of learning more about how saxitoxin levels magnify and diminish as they move through the food chain, from phytoplankton to mussels and up to seabirds.

“We don’t really know how this toxin moves through the food web,” said Sarah Schoen, a USGS wildlife biologist that recently collected marine samples in Unalaska. “There’s still a lot of unknowns, but the more information we can collect about it, the more we’ll understand it.”

Schoen said the project started about five years ago when a major heat wave, known as “the blob,” hit the ocean. Around the same time, there was a die-off of an estimated million common murres — a northern seabird — from Alaska down to California.

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.

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.

These fish started life as boys. Now scientists aren’t sure what sex they are.

For male smallmouth bass, sex change is increasingly not an option. In the chemical-laced Chesapeake Bay watershed and in rivers up through New England, it comes with the territory.

Based on the latest U.S. Geological Survey on intersex fish, 85 percent of male smallmouth bass in waters in and around national wildlife refuges in the Northeast have developed “characteristics of the opposite sex.” That’s in addition to 90 percent of the species in some West Virginia waters and 50 percent to 100 percent in the southern stretch of the Potomac River. All of the affected fish had eggs where their testes should be, according to previous studies.

Why this is happening remains a mystery, says the lead author of a new study, despite the problem being detected more than a decade ago. “It is not clear what the specific cause of intersex is in these fish,” said Luke Iwanowicz, a USGS research biologist. “This study was designed to identify locations that may warrant further investigation.”

UMass and USGS: Climate Change Affecting Fish And Wildlife In New England

June 30, 2015 — A new environmental report from UMass and the U.S. Geological Survey warns that climate change continues to affect New England fish and wildlife.

USGS ecologist Michelle Staudinger says the study confirms previous findings – that temperatures are going up in all seasons, and especially winter. That means there’s more rain and less snow, which changes the flow of streams in the spring.
