Saving Seafood

To save the world’s rarest marine mammal, conservationists seek ban on Mexican seafood imports

July 12, 2018 — A decade of rescue crusades by conservation groups, hard-core eco-activists and the U.S. Navy have failed to prevent the world’s rarest porpoise from becoming fatally entangled in gill nets set for seafood in Mexico’s northern Gulf of California.

Now, with less than 20 vaquita left in the wild, the prospect of the species’ extinction within two years has prompted a last-ditch effort with significant economic and political consequences for the United States and Mexico.

Conservationists on Tuesday asked an international trade court judge in New York for a preliminary injunction banning imports of an estimated $16 million worth of fish and shrimp harvested with gill nets in an area of the gulf roughly a third the size of Los Angeles County and just three hours south of the border.

U.S. Court of International Trade Judge Gary Katzmann said he would rule within two weeks. His decision may hinge, in part, on whether the costs of implementing an embargo to save the species are greater than the costs of its disappearance.

The Chesapeake Bay hasn’t been this healthy in 33 years, scientists say

June 18, 2018 — For the first time in the 33 years that scientists have assessed the health of the Chesapeake Bay, the nation’s largest estuary showed improvement in every region, a likely sign that a massive federal cleanup plan is working.

The bay’s most important species — blue crabs and striped bass, which support commercial and recreational fisheries, and anchovies, the foundation of its food chain — earned top scores in a report card released Friday. Bright green underwater grasses — which help protect young fish before they venture into the Atlantic Ocean — are now thriving, even in some places where such vegetation had disappeared.

In sharp contrast to the days when the bay was so beleaguered that every meaningful species experienced sharp population declines, officials and scientists from the District, Maryland and Virginia announced Friday that it is in the midst of a full and remarkable recovery. As if to underscore the progress, their backdrop along the District’s southwest waterfront was a brilliantly sunny morning and a picturesque view of the Anacostia River, which feeds into the Chesapeake.

The news comes at a time when hundreds of bottle-nosed dolphins have been seen frolicking in the bay, including a large pod off Maryland’s Ragged Point last month. On Tuesday, two great white sharks were hooked by scientists in Virginia. The number of fish-hunting osprey is also on the rise.

The bay’s overall grade is a C, because some areas, such as the Patuxent, Patapsco and York rivers, are bouncing back from near-failure. The category of water clarity faltered, falling to an F from last year’s D. But the James River area and the lower stem of the bay closer to the Atlantic both earned grades of at least B-, their highest ever, and shored up the overall score.

Oil exploration raises issue of undersea munitions, including Tybee bomb

May 1, 2018 — Frank Knapp has been battling the prospect of offshore drilling for years, convinced the industry’s infrastructure or a major spill would spoil the lucrative tourism and commercial fishing industries in the Southeast.

Lately, though, he’s sounding a new alarm that focuses not on oiled beaches or injured dolphins but on the huge quantities of undersea munitions dumped off the East Coast following WWI and WWII. And off the Georgia coast, he points out, there’s the additional question of the never-located “Tybee bomb,” a nuclear weapon lost during a training exercise 60 years ago.

“Government documents and first-hand accounts of munitions and radioactive waste being dumped off the Atlantic Coast from Massachusetts to Florida came to our attention only recently,” Knapp, president and CEO of the S.C. Small Business Chamber of Commerce, wrote in recent comments to federal regulators. “Nine of the official dump sites are off the South Carolina coast. There is a serious threat of seismic airgun blasting disturbing these materials, many in unofficial and unknown locations and all in deteriorated containers, and releasing them into the water. Commercial fishing, the public, local economies and even seismic ships and crews are in jeopardy.”

Seismic testing uses repeated loud blasts of compressed air to map the sea floor. The Bureau of Ocean Energy Management has proposed mitigation to protect sea life from the effects of the barrage of underwater noise, but concerns persist that the air guns will harm sea life ranging from plankton to whales. The issue of its effects on undersea ordinance, however, is a new one.

Senators Feinstein, Harris introduce bill to ban drift nets in California

April 30, 2018 — A bipartisan bill to ban controversial drift net fishing off California’s coast was introduced Thursday by Democratic California Sens. Dianne Feinstein and Kamala Harris, along with West Virginia Republican Sen. Shelley Moore Capito.

The nets, which can be more than a mile long, are intended to catch swordfish but end up trapping dolphins, sea lions and a host of other marine life, many of which die.

“The use of drift nets to target swordfish harms too many endangered or protected marine animals and should be phased out,” Feinstein said in an emailed statement. “It’s unacceptable that a single California fishery that uses this type of drift net is killing more dolphins and porpoises than the rest of the West Coast combined.”

Large mesh drift nets are already banned in the Atlantic Ocean and Gulf of Mexico, as well as off the coasts of Washington, Oregon, Alaska and Hawaii, according to Feinstein. Additionally, the United States is a signatory to international agreements that ban large drift nets in international waters.

Scientists study how marine mammals survive at great depths

April 30, 2018 — Whales, dolphins and seals have evolved to hunt prey deep in the ocean, an environment that would otherwise prove deadly to animals that depend on breathing air to live. Until recently, scientists believed marine mammals’ known physical adaptations protected them from the effects of such punishing depths.

But scientists were baffled by computer models that showed that, even with the known adaptations, 50 percent of animals studied still should have experienced the bends. Researchers concluded there must be some else going on.

A new study by the Woods Hole Oceanographic Institution and the Oceanographic Foundation of the City of Arts and Sciences in Valencia, Spain, may provide an answer. The study, funded by the U.S. Navy, found that deep-diving marine mammals use a physical adaptation — the collapse of one portion of the lungs — to block the flow of nitrogen into the blood and prevents the animals from getting the bends, the crippling release of nitrogen gas that can occurs when surfacing from dives deeper than 130 feet.

“If you get the conditions right, you can get a nice exchange of oxygen and carbon dioxide but block the nitrogen,” said Michael Moore, a WHOI senior scientist who specializes in the analysis of marine mammal mortalities. Moore is a co-author of the study, which was published April 25 in the journal “Proceedings of the Royal Society B.”

The mammals have other physical adaptations that help them survive the depths when they exhaust available oxygen in their lungs, including a high amount of proteins in blood and muscle that bind oxygen and a higher ratio of red to white blood cells. Their ribs and lungs can collapse under pressure without breaking and their airways are hardened bunkers that remain partially open to power the signals they use to locate one another and their prey.

Sharks, Dolphins, and Turtles are Turning Up in Strange Places Because of Climate Change

April 20, 2018 — Luke Halpin couldn’t believe his eyes. In the early morning hours from his spot on a research ship in the Pacific Ocean, he was seeing bottlenose dolphins. If Halpin had been on a ship off the coast of California, this wouldn’t be remarkable. But he was on a Canadian research vessel floating about 100 miles northwest of Vancouver. These dolphins had never been seen alive north of the waters off the coast of Washington state.

“My initial reaction was one of disbelief,” he told Newsweek. “But they’re an unmistakable species. They’re easy to identify.”

Halpin’s next reaction was to start counting and pull out his camera. In total, he spotted about 200 dolphins and 70 false killer whales—a very large group—that came within a few hundred feet of the ship. He and his colleagues published their observations in Marine Biodiversity Records on Thursday.

Salmon survival: ‘We need more lethal removal of sea lions. Hazing is not the answer’

April 6, 2018 — Ted Walsey’s shotgun cracked like thunder, lobbing a cracker shell into the Columbia River and sending the big brown sea lion beneath the surface in search of friendlier waters. But the boat and the noises emanating from it weren’t far behind.

Just as crews from the Columbia River Inter-Tribal Fish Commission have for a number of years, Walsey, Bobby Begay and Reggie Sargeant patrolled the river just below Bonneville Dam on Wednesday afternoon, harassing but not killing sea lions with cracker shotgun shells and so-called seal bombs — both essentially big firecrackers, the former shot from a shotgun, the latter dropped by hand — downstream and away from the fish ladders, where endangered migratory salmon congregate.

For the salmon, it’s the first chokepoint on a long journey to their spawning grounds. For hungry sea lions, it’s like a quick trip to an all-you-can-eat buffet.

The National Oceanic and Atmospheric Administration Fisheries division estimates about 45 percent of spring chinook salmon are lost between the mouth of the Columbia and Bonneville Dam, with sea lions being primarily responsible.

Sea lions — as well as whales, dolphins and porpoises — are protected under the Marine Mammal Protection Act. For the last 15 years or so, states and tribes have been able to kill some sea lions, but they have to go through a long and laborious permitting process to do so on an animal-by-animal basis.

NOAA publishes global list of fisheries and their risks to marine mammals

April 3, 2018 — The U.S. National Oceanic and Atmospheric Administration (NOAA) has published the first list of foreign fisheries, detailing the risks that commercial fishing around the world pose to marine mammals.

“The [List of Foreign Fisheries] is an important milestone because it provides the global community a view into the marine mammal bycatch levels of commercially relevant fisheries,” according to a statement published on the NOAA Fisheries website.

“In addition, it offers us a better understanding of the impacts of marine mammal bycatch, an improvement of tools and scientific approaches to mitigating those impacts, and establishes a new level of international cooperation in achieving these objectives,” the statement says.

The register is a step toward meeting specific requirements in the Marine Mammal Protection Act on the sources of fish imported into the U.S. It includes nearly 4,000 fisheries across some 135 countries. These fisheries have until 2022 to demonstrate that the methods they use to catch fish, as well as other marine animals such as coral, crabs, lobsters and shellfish, either aren’t much of a danger to marine mammals, or they employ comparable methods and mitigation measures to similar operations in the United States.

Fishing nets can exact a high toll on animals that fishers don’t intend to catch. Nets themselves can trap dolphins, porpoises, seals and sea lions as bycatch. In Mexico, a fishery targeting the totoaba for its swim bladders that fetch high prices in Asian markets has decimated the tiny porpoise known as the vaquita (Phocoena sinus). Perhaps as few as 12 remain in the wild.

The lines from traps, pots and nets can also ensnare even the largest animals in the ocean. Recent research has shown that almost every one of the estimated remaining 451 North Atlantic right whales (Eubalaena glacialis) either is toting errant fishing equipment around or it bears the scars of entanglements with gear. These ropes can cause injuries to right whales and other animals that can lead to infection or death. And towing pieces of gear that can be longer than the whale’s body causes what scientists call “parasitic” drag that can interfere with the ability to find food.

Zero Dollars for Marine Mammals?

February 27, 2018 — The future of marine mammals is at risk in U.S. waters. President Trump’s proposed budget for fiscal year 2019 would eliminate the Marine Mammal Commission. With an annual operating budget of $3.4 million, which comes to just over one penny per American per year, the Marine Mammal Commission has for 45 years been assiduously developing science and policy to protect seals, sea lions, dolphins, whales, dugongs and walruses. Through the 1972 Marine Mammal Protection Act (MMPA), Congress charged the commission with providing independent oversight of marine mammal conservation policies and programs being carried out by federal regulatory agencies. Obviously, with a proposed budget of zero dollars, it would be impossible to execute the federally mandated objectives of fostering sustainable fisheries (through the Magnuson-Stevens Fishery Conservation and Management Act [MSA]) and protecting endangered species (through the Endangered Species Act [ESA]).

Marine mammals are more than just lovable creatures. They are important components of productive marine and coastal ecosystems that overall generate $97 billion of the gross domestic product. Whales function as ecosystem engineers by cycling vital nutrients between deeper and surface waters in the oceans. Without this nutrient cycling, oceans would produce less plankton and phytoplankton, which would eventually mean less fish. Also, through complex food-web interactions, marine mammals help to regulate fish populations. For example, marine-mammal–eating killer whales (often called “transient” killer whales) will eat seals, a common predator of pelagic fish—enabling fish populations to stay high. This kind of interaction is called a trophic cascade and is very common in marine ecosystems.

Serving as an independent oversight body, the commission has the critical task of assessing the scientific validity and effectiveness of research conducted to meet the federal mandates of the MMPA, ESA and MSA. If we as a country can’t even protect the charismatic species, I worry for all the less adorable parts of nature. So we need to draw a line in the sand. In this era of “fake news,” maintaining this entity to guard against encroachments to science-based policymaking on is more valuable than ever.

NOAA Announces New Marine Mammal Stranding Response Organization in Nantucket

February 9, 2018 — The following was released by NOAA Fisheries:   

Today, NOAA Fisheries announces that Marine Mammal Rescue Nantucket is now an authorized marine mammal stranding response organization for Nantucket, Tuckernuck, and Muskeget Islands.

After four years of no stranding coverage on Nantucket and the outer islands, Marine Mammal Rescue Nantucket (known as MMRACK, after ACK – the call letters for Nantucket Airport) fills an important gap in the GARFO network. Led by Marine Mammal Alliance Nantucket CEO Scott Leonard, who spent more than a decade working as a stranding volunteer with New England Aquarium, MMRACK will respond to both live and dead whales, dolphins, and seals. In addition to assessing and providing transportation for animals in need of treatment, Leonard’s team, which consists of seasoned volunteers who have worked or trained with the New England Aquarium, will also perform necropsies (animal autopsies) on dead animals.

“Nantucket is a unique place with a rich marine mammal history,” says Leonard. “MMRACK’s mission is to provide public education and outreach with the focus on raising awareness of human and marine mammal interaction, while providing humane care to our marine species. We are looking forward to being part of the network, and plan on working closely with International Fund for Animal Welfare, Marine Mammals of Maine, U.S. Coast Guard, Massachusetts Environmental Police, and other regional partner organizations.”

NOAA Fisheries looks forward to working with MMRACK to increase stranding response capabilities on Nantucket, and to help with monitoring marine mammal populations and health.

“Nantucket is an important area for marine mammal populations, particularly gray seals that breed and pup there,” says Mendy Garron, NOAA Fisheries Greater Atlantic Region Marine Mammal Stranding Response Coordinator. “Having a stranding response organization on the island will help us track the health and welfare of these populations and help reduce conflicts through education and outreach.”

Please report stranded marine mammals on Nantucket, Tuckernuck, and Muskeget to the Marine Mammal Rescue Nantucket Hotline: 833-667-6626.
