Report highlights how tuna fisheries can reduce bycatch

April 4, 2018 — Four environmental organizations have joined forces in an effort to reduce the amount of bycatch produced by longline tuna fishing operations.

In working with Greenpeace, Birdlife International, and The Nature Conservancy, Sustainable Fisheries Partnership released in late March detailing the impact longline practices have on other species. They hope to influence processors and retailers who wish to market sustainable tuna and want to improve the environmental performance of the fisheries who supply them.

In some cases, the species most impacted by longline tuna operations are endangered or vulnerable, such as sharks and sea turtles. Other species that can find themselves entangled in the lines include baleen whales and seals.

Opponents say Block Island wind farms are causing problems across prime fishing grounds

March 19, 2018 — NEW BEDFORD, Mass. — The five enormous turbines that have been generating electricity off Block Island over the past year are considered a model for the future of offshore wind.

But the nation’s first ocean-based wind farm also has exposed what fishermen say are serious threats to them caused by scattering massive metal shafts and snaking underwater cables across prime fishing grounds.

With state officials poised to announce the winners of bids to develop much larger wind farms south of Martha’s Vineyard, fishermen across the region have been pressing officials for answers to their concerns about where the turbines will be located, how far apart they’ll be built, and the placement of the cables to the mainland.

“It’s true that the area where the turbines are have created habitat that attracts fish, which is good; but in the area where the cable lines extend to the mainland, it’s completely devoid of fish,” said Michael Pierdinock, chairman of the Massachusetts Recreational Alliance, which represents about 50,000 recreational fishermen. “Theseused to be fruitful fishing grounds.”

The opposition of the fishing industry, a powerful interest group in New England, could prove a hindrance for developers of the proposed wind farms, which will be chosen next month.

Those projects, which could ultimately span hundreds of thousands of acres some 14 miles south of Martha’s Vineyard, are expected to generate 1,600 megawatts of power within a decade, or enough electricity for about 800,000 homes.

At a meeting last month in New Bedford of fishermen, developers, and state and federal officials, Pierdinock and commercial fishermen urged regulators to study the potential impact of the proposed wind farms on marine mammals, spawning grounds of herring and squid, and other species that inhabit the area.

Alaska: In Nome, state experts ponder responses to Bering Sea crises

February 21, 2018 — Experts from around the state gathered in Nome to discuss marine mammals and how multiple entities can respond to different types of emergencies that may happen in the Bering Sea.

Mandy Migura with the National Marine Fisheries Service was one of the presenters at a “Strait Science” talk hosted at University of Alaska Fairbanks Northwest Campus.

Migura discussed how marine mammal stranding events take place in Alaska sporadically but have been rising in numbers since tracking began in the 1980s.

“Strandings involve live marine mammals. these may be animals that are unable to return to their natural habitat without some kind of assistance. And they may be injured, they may be entangled in gear or marine debris, they may be entrapped — ice entrapment, ice may form up and they’re in an area where they can’t get back to where they should be — or they may be disoriented, may be a health issue or something in the environment that’s affecting them.”

Migura is Alaska’s marine mammal stranding coordinator and said dead marine mammals can also be categorized as stranded.

With more cases of marine mammal strandings being reported, the Bering Sea marine ecosystem is currently in a volatile state.

Nome-based marine advisory agent Gay Sheffield mentioned how sharks have been found more frequently in the Bering Straits region, with the latest one documented in Gambell in summer 2017.

On the other side of St. Lawrence Island, a stellar sea lion was harvested last year in Savoonga, which she said is uncommon.

Migura said local and regional partners reporting this kind of information greatly benefits the National Marine Fisheries Service.

Marine debris threatens Hawaii’s ecosystem, but collecting it can get complicated

February 15, 2018 — Marine debris continues to litter our beaches, and more of it is on the way if our current weather patterns continue.

Nets, floaters, and other rubbish aren’t just ugly and dangerous to marine life.

They hide small organisms and creatures that could harm our fragile shorelines.

Scott Godwin works with the Hawaii Department of Land and National Resources Division of Aquatics Resources Aquatic Invasive Species (AIS) team. He’s been studying invasive species and marine debris for more than 15 years.

“There’s a lot of stuff out there all the time,” Godwin said, “and Hawaii seems to be in the right place to get that stuff just because of the oceanographic conditions.”

He explained that the current winds and currents have simply been washing debris onshore that would normally otherwise float by the islands and go unnoticed.

The debris poses many dangers. Marine mammals and fish get tangled in floating masses of nets and die.

Fossil fuel search would target migratory path of right whales

November 14, 2017 — Conservationists will gather today in Washington, D.C., to stop a bill they say will “fast-track” air gun surveys for oil and gas off the U.S. coasts that could harm whales, dolphins and other marine mammals.

“This is a pro-oil and gas industry wishlist,” said CT Harry, a marine conservation campaign officer for the International Fund for Animal Welfare, which is one of the nine lead conservation groups heading the lobbying effort.

More than 50 marine mammal advocates and ocean conservationists are expected to visit Capitol Hill, on the 45th anniversary of the passage of the federal Marine Mammal Protection Act.

The act, enacted in 1972, established a moratorium on the taking of marine mammals in U.S. waters, where “take” means hunt, harass, capture or kill, or attempt to do so, and the act set a national policy to prevent depletion of marine mammal populations. Exceptions to the moratorium can be made through permits for lawful activities that might incidentally result in a “take.”

Conservationists say that House bill 4239, known as the Secure American Energy Act, contains provisions to weaken the MMPA permitting for “incidental” events, where the weakened measures could harm marine mammals all along the East Coast, particularly the North Atlantic right whales. The House Committee on Natural Resources passed the bill last week, and the House could vote on it in the next few weeks.

Copepods: Cows of the Sea

October 6, 2017 — If you look very closely at a glassful of water from a bay or the ocean, you would probably be surprised by the life inside. You might see miniature crustaceans the size of the period at the end of this sentence or baby crabs and fish that spend only a short span of their lives this small. These creatures are zooplankton, aquatic animals that drift with the currents.

It’s the Little Things 

These tiny animals form the basis of the food web of estuaries, coastal waters, and oceans. Zooplankton feed on microscopic plant-like organisms called phytoplankton, which get their energy from the sun. Tiny crustacean zooplankton called “copepods” are like cows of the sea, eating the phytoplankton and converting the sun’s energy into food for higher trophic levels in the food web. Copepods are some of the most abundant animals on the planet.

Fish such as anchovies cruise through the water with their mouths wide open, filtering copepods and other zooplankton from the water. Anchovies and other planktivores (plankton-eaters) are prey for bigger animals, like tuna, sharks, marine mammals, and seabirds.

Whale habitat change concerns fishermen

February 2, 2016 — GLOUCESTER, Mass. — NOAA Fisheries announced last week that it was expanding the critical habitat for endangered North Atlantic right whales to cover its northeast feeding areas in the Gulf of Maine and Georges Bank. The designated area is much larger than the one it replaces, and now includes all of the Gulf of Maine on the U.S. side of the national boundary with Canada.

The designation also was applied to an expanded area of the whales’ southeast calving grounds from North Carolina to Florida.

Under the Endangered Species Act, critical habitat within the range of the species consists of areas that contain physical or biological features essential to conservation of the species.

The final rule, which was first proposed in February 2015 and received 261 general comments over a 60-day comment period, does not include any new restrictions or management measures for commercial fishing operations. It does not create preserves or refuges.

However, federal agencies conducting, funding or permitting activities in these areas are required to work with NOAA Fisheries to avoid or reduce impacts on critical habitat.

The announcement has sparked long-standing disagreements between environmental and animal organizations and commercial fisheries.

Humane Society CEO Wayne Pacelle called the decision “a lifeline” for right whales in a blog post published Friday. “The HSUS and its allies have been fighting for an expansion of protected habitat since 2009, and it’s a victory for us over commercial fishermen and shipping interests that have irresponsibly downplayed their role in driving down the numbers of these mammoth creatures,” he wrote.

Study measures drag from fishing gear entanglements on North Atlantic right whales

December 9, 2015 — Entanglement in fishing gear is the leading cause of death for North Atlantic right whales—one of the most endangered of all the large whale species. Their migratory routes take them through some of the busiest commercial fishing areas along the East Coast of the United States and into Canada.

Entangled whales can tow fishing gear for tens to hundreds of miles over months or even years, before either being freed, shedding the gear on their own, or succumbing to their injuries.

In a paper published online Dec. 9, 2015, in Marine Mammal Science, a research team led by the Woods Hole Oceanographic Institution (WHOI), has for the first time quantified the amount of drag on entangled whales that is created by towing fishing gear, such as rope, buoys, and lobster and crab traps. The study provides important data for teams evaluating the risks and benefits of whale disentanglements.

“We know that entanglement can change a whale’s diving and swimming behavior and depletes their energy,” said Julie van der Hoop, lead author of the paper and a PhD Candidate in the MIT-WHOI Joint Program in Oceanography, “but the big thing we have never really known is what it must be like for animals to tow the gear. Is it like wearing an empty backpack or is that backpack overloaded with heavy books? Does removing part of the gear improve chances of survival? These are some of the questions that we were looking to answer with this research.”

Toxin Taints Crabs and Kills Sea Mammals, Scientists Warn

November 4, 2015 — The authorities in California are advising people to avoid consumption of crabs contaminated by a natural toxin that has spread throughout the marine ecosystem off the West Coast, killing sea mammals and poisoning various other species.

Kathi A. Lefebvre, the lead research biologist at the Wildlife Algal Toxin Research and Response Network, said on Wednesday that her organization had examined about 250 animals stranded on the West Coast and had found domoic acid, a toxic chemical produced by a species of algae, in 36 animals of several species.

“We’re seeing much higher contamination in the marine food web this year in this huge geographic expanse than in the past,” Ms. Lefebvre said.

She said that the toxin had never before been found in animals stranded in Washington or Oregon, and that there were most likely greater numbers of contaminated marine mammals not being found by humans.

The California Department of Public Health recently advised people to avoid consumption of certain species of crabs because of potential toxicity. Razor clam fisheries in Washington have been closed throughout the summer for the same reason.

In a statement released on Tuesday, the California department said that “recent test results” indicated dangerous levels of domoic acid in Dungeness and rock crabs caught in California waters between Oregon and Santa Barbara, Calif.

US probes dolphin death after Navy uses sonar

November 4, 2015 — HONOLULU (AP) ” The National Marine Fisheries Service on Wednesday said it was investigating the death of two dolphins found washed ashore in California shortly after Navy ships were using sonar in nearby waters.

The animals are being analyzed to try to determine what caused them to get stranded, agency spokesman Jim Milbury said.

The dolphins were common bottlenose dolphins, Navy spokeswoman Lt. Julie Holland said. They were found Oct. 21 at Imperial Beach and at Silver Strand beach in San Diego.

Two Navy ships were using mid-frequency active sonar 80 nautical miles away from where the dolphins were found, Holland said. They used the sonar for slightly more than an hour over two days from Oct. 19.
