  • New rules allow for cleanup of ‘ghost gear’

    BOSTON — State fisheries managers unveiled new rules this week aimed at reducing discarded fishing line and other waste that scientists say harms marine life, including sea turtles and critically endangered North Atlantic right whales.

    The state Division of Marine Fisheries said Tuesday the new regulations, which take effect Friday, will strike a balance between the need to clean up derelict fishing gear to protect marine life and “continuing to protect functional fishing gear and minimizing conflicts on the water.”

  • OSU Researchers Play Pivotal Role In Global High Seas Treaty – KXL

    Corvallis, Ore. – Researchers at Oregon State University played a key role in an historic global conservation effort. Known officially as the Biodiversity Beyond National Jurisdictions Agreement, the High Seas Treaty takes effect Saturday.

    OSU’s Kirsten Grorud-Colvert admits the High Seas are a vast area, It’s two-thirds of the ocean, which means it’s like half of our planet.” She adds, “This is international waters, where, up to this point, there hasn’t been a mechanism for creating this conservation for biodiversity.” Grorud-Colvert was part of a team of more than three dozen scientists from 13 countries that developed a roadmap for planning and creating Marine Protected Areas (MPAs). “There are incredibly thriving ecosystems on things like seamounts, whales, tuna, all these species we know and love. Now we’ll have an opportunity for the global community to consider how best to conserve and protect them.” She says some of those ecosystems and species have yet to be discovered. The MPA Guide: A framework to achieve global goals for the ocean they created was published in September 2021.

    Work on that guide began when Jenna Sullivan-Stack was a grad student at OSU. She saw, “A very diverse, broad set of expertise that’s been contributing over years. And it’s all based on scientific studies that have taken place over decades.” Now, as an OSU Research Associate, she says it’s rewarding to see the work culminate with ratification of the treaty. “How we implement it is really the work that’s to come and it’s going to be hard work, a lot of compromise, a lot of listening. And our work is sort of calling for science to play a lead role in those conversations.”

    Grorud-Colvert and Sullivan-Stack wrote an editorial on the treaty, published Thursday in Science. For more on the treaty and the work to protect the High Seas, visit the High Seas Alliance website.

    Palau was the first nation to ratify the High Seas Treaty, in 2024. Morocco became the 60th on September 19, 2025, setting a 120-day clock for it to take effect on January 17, 2026. The guide developed in part at OSU will be used as the UN takes up that conversation starting in about a month.

  • Jaw-Dropping Video Shows Orcas Flipping a Great White Shark to Feast On Its Liver

    Orcas are called “killer whales” for a reason. These apex predators are adept pack hunters, using coordinated attacks and specialized techniques to take down their prey.

    Scientists recently captured stunning drone footage of a pod of orcas in the Gulf of California killing juvenile great white sharks by flipping them upside down and feasting on their livers. Researchers described the attacks in a new study published Monday in the journal Frontiers in Marine Science.

    The video is the work of the study’s lead author, marine biologist and wildlife underwater cinematographer Erick Higuera, and Marco Villegas. Higuera has been filming and studying orcas for more than a decade, but the first time he observed this particular shark-hunting behavior was in August 2020. At first, he couldn’t tell based on the drone footage what species of shark the pod was hunting.

    “I thought, ‘Well, it might be a sand tiger shark,’ you know—one of those similar looking sharks. But I never thought that it was going to be a great white,” Higuera told Gizmodo.

    Bewildering behavior

    While interactions between these two lethal predators are considered rare, scientists have documented orca attacks on great white sharks in South Africa, Australia, and other areas of the California coast. Killer whales target these sharks for their nutrient-rich livers, which can weigh up to 1,300 pounds (600 kilograms), according to Higuera—that’s about a quarter of the shark’s total mass.

    Flipping sharks upside down is a common hunting strategy orcas use to induce a state of tonic immobility. The move temporarily paralyzes the shark, preventing it from fighting back. It also gives orcas direct access to their liver.

    What’s unique about this pod of orcas in the Gulf of California is that they are targeting juvenile great whites as opposed to adults, study co-author Salvador Jorgensen, a marine ecologist and assistant professor at California State University Monterey Bay, told Gizmodo.

    Orcas tend to hunt adult great whites because they offer a bigger reward. “The liver is much larger,” Jorgensen explained. “But what we’re seeing in the Gulf of California is that they’re repeatedly going after small individuals that maybe were born a year or two ago.”

    Figuring out what’s driving these orcas to target young great whites instead of adults will require further research, but the authors have some ideas about the advantages this strategy may offer.

    Shifting hunting tactics

    What juvenile great white sharks lack in liver size they may make up for in ease, according to the researchers. It might just be simpler for a pod of orcas to flip a younger, smaller great white onto its back, enabling an easier kill.

    Juvenile great whites may also be more naive than adults. Fully grown great whites have an uncanny ability to sense when orcas are near. “If they even get the tiniest scent or hint of an orca, all of those white sharks will flee from that area,” Jorgensen explained. If that’s a learned behavior, this would suggest that younger sharks are more vulnerable to orca attacks, he said.

    “Maybe they don’t have that flight strategy developed yet,” Higuera suggested.

    Climatic shifts could be playing a role as well. The increased frequency of El Niño events and marine heat waves in the Pacific Ocean appear to have altered great white shark nursery areas, increasing their presence in the Gulf of California. That shift may have presented this particular pod of orcas with an opportunity, offering up seasonal cohorts of juveniles.

    Whatever the case, documenting repeated orca attacks on juvenile great whites for the first time raises many new questions about both species and their interactions. “It’s exciting that in this day in age when we have sensors and cameras everywhere, we’re still finding new stuff,” Jorgensen said. “There’s still mysteries like this in the ocean.”

  • Stranded dolphins may have Alzheimer’s, say scientists

    Some dolphins found stranded on beaches may have ended up their because they suffer from a form of Alzheimer’s disease linked to toxins in the water. 

    This is the conclusion of a study led by researchers from Florida’s Hubbs-SeaWorld Research Institute, who suspect that—just like some adult humans with dementia are occasionally found wandering far from their homes—dolphins may become similarly disoriented when suffering from Alzheimer’s. 

    Their findings, published in the journal Communications Biology, point to chronic exposure to toxins produced by microorgansims known as cynobacteria—which are frequently found in freshwater, estuarine and marine waters—as a possible trigger. 

    The cyanobacterial toxin β-N-methylamino-L-alanine (BMAA), as well as its isomers 2,4-diaminobutyric acid (2,4-DAB), and N-2-aminoethylglycine (AEG), have been found to be extremely toxic to neurons.

    BMAA triggers Alzheimer’s-like neuropathology and cognitive loss in experimental animals. These toxins can be biomagnified as they accumulate up the food chain in the marine ecosystem towards top predators like dolphins. 

    The resarcher’s study, which involved 20 common bottlenose dolphins stranded in the Indian River Lagoon in eastern Florida during the summer cyanobacterial bloom season, identfied markers of Alzheimer’s disease. 

    The duration of cyanobacterial blooms is increasing due to climate change and nutrient pollution from agricultural runoff and sewage discharges. Cyanobacterial-laden waters have often been released down the St. Lucie River from Lake Okeechobee into the Indian River Lagoon, intensifying exposure risks even in humans. 

    “Since dolphins are considered environmental sentinels for toxic exposures in marine environments, there are concerns about human health issues associated with cyanobacterial blooms,” said paper author and neuropathologist Dr. David Davis of the University of Miami said in a statement.

    Studies of villagers on the island of Guam show that chronic dietary exposure to cyanobacterial toxins are associated with misfolded tau proteins and amyloid plaques characteristic of Alzheimer’s disease. 

    “Among Guam villagers, exposure to cyanobacterial toxins appeared to trigger neurological disease,” explained Dr. Paul Alan Cox, of the Brain Chemistry Labs in Jackson Hole, in a statement. 

    In 2024, Miami Dade County had the highest prevalence of Alzheimer’s disease in the United States.

    “Although there are likely many paths to Alzheimer’s disease, cyanobacterial exposures increasingly appear to be a risk factor,” adds Dr. Davis.

  • Dive Into the Most Breathtaking Ocean Photos of the Year

    While floating in the crystal-clear waters of the northern Great Barrier Reef, a sleek, dark shape glided toward Marcia Riederer. The Brazilian-born wildlife and underwater photographer watched as the dwarf minke whale approached, snapping a photo at the exact moment it turned and fixed one eye on her.

    “These curious giants approach swimmers with an almost playful curiosity,” Riederer told Oceanographic Magazine. “The whales seem to acknowledge your presence, circling and interacting with you. It’s a humbling experience, reaffirming the wonder of the ocean and its inhabitants, and the urgent need to conserve it.”

    Her stunning photo, shown above, won Riederer first place in the fine art category of the 2025 Ocean Photographer of the Year awards. This competition, presented by Oceanographic and Blancpain, honors awe-inspiring images that showcase the ocean’s beauty and its fragility. Read on to dive into the rest of this year’s winning photos.

    Wildlife photographer of the year: Takumi Oyama

    The yellow pygmy goby is a small, brightly colored fish native to the western Pacific Ocean. Japanese marine researcher Takumi Oyama photographed this one mid-larval dispersal. “In gobiid fishes, male parental care is common, but unusually, in the yellow pigmy goby, females also participate in parental hatching care,” he explained. “This individual is a female, releasing newly hatched larvae into the water column from her mouth.”

    Oyama’s research focuses on the reproductive ecology of fish, particularly of reef fish in Japan. He conducts scuba-based fieldwork to get up close and personal with marine life, using underwater photography to aid his research and share his observations with the world.

    The coast of Nazaré, Portugal, is infamous for its massive waves, producing some of the largest swells ever surfed. French photographer Ben Thouard snapped this dramatic shot on a particularly rough day. “The wind was blowing from the north which makes the surf tricky,” he said. “It was the end of the afternoon; the light was interesting from the beach instead as from the usual cliff view. It was hard to shoot anything because of the big sets and the saltwater in the air. But, eventually, this moment happened.”

    Thouard has been photographing the ocean ever since he was a teenager. He is now based in Tahiti—another part of the world known for its powerful waves—where he has developed his unique visual style.

    The traditional whaling practice of grindadráp is deeply rooted in centuries of Faroese culture. The hunts were once critical to human survival in the Faroe Islands, but today, conservationists argue that the mass killing of pilot whales poses a significant threat to the species. French photographer and marine biologist Hugo Bret captured this evocative image of a long-finned pilot whale fetus lying lifeless under its mother’s corpse after one such hunt.

    “Each year, more than 1,000 cetaceans are killed during grindadráp, the slaughter of entire whale groups, including juveniles and pregnant females,” he said. “While these hunts were once an existential necessity, they are no longer subsistence practices. I hope this image drives global attention to end the grindadráp and, at a broader scale, advocates for a reconsideration of what the human relationship with other living beings should be.”

    Indo-Pacific leopard sharks were once abundant in the Coral Triangle, an area of exceptional marine biodiversity in the western Pacific. Today, this species is on the International Union for Conservation of Nature (IUCN) list of endangered species, driven nearly to extinction by overfishing and habitat loss.

    This striking photo by Thai photojournalist and marine biologist Sirachai Arunrugsticha offers a glimmer of hope. “An aquarist holds a glass jar with an early-stage embryo of an Indo-Pacific Leopard shark (Stegostoma tigrinum), its egg case removed for a rearing experiment at Aquaria Phuket, one of Thailand’s largest private aquariums,” he explained. “Since 2023, the aquarium’s staff-driven breeding program has produced over 40 pups of this Endangered species, listed on the IUCN Red List.”

    Rescue teams and local community members worked for 15 hours to save this humpback whale that became beached in New South Wales, Australia. Australian ocean and nature photographer Craig Parry documented the tireless effort, snapping this aerial photo.

    “Sadly, despite their dedication, she could not be saved,” Parry said. “While the outcome was heartbreaking, witnessing the collaboration and compassion shown by multiple agencies and volunteers was incredibly moving—a powerful reminder of what can be achieved when people come together with a shared purpose.”

    These iridescent bobtail squid are wrapped in a tender embrace, mating on the seabed off the coast of the U.K. Underwater photographer and filmmaker Aaron Sanders carefully approached so as not to disturb the pair, capturing this dazzling photo.

    “Waves of color rippled across their bodies as chromatophores pulsed in a mesmerizing rhythm, white flickered to gold, gold to red, and back again, transforming them into living, glowing jewels in the dark,” Sanders said. “These otherworldly creatures performed their courtship, creating the next generation of Bobtail squid.”

    What looks like hundreds of tiny eyeballs in this male jawfish’s mouth is actually his own offspring. Mouthbrooding jawfish protect their fertilized eggs by carrying them around in their mouths for a week or more. During this period, they refrain from eating and regularly “juggle” the eggs—essentially spitting them out then sucking them back in—to make sure they receive enough oxygen.

    “2025 was an exceptional year for spotting mouthbrooding males,” said Florida-based underwater and wildlife photographer Matthew Sullivan. “This particular male was quite bold and once he became comfortable with me, he allowed me to take this image.”

    The overall winner of this year’s Ocean Photographer of the Year awards is Indonesia-based photographer and dive master Yury Ivanov. He captured this colorful image of two amphipods from the Cyproideidae family, each only measuring around 3 mm in body length, resting on a coral.

    These tiny creatures are commonly known as “ladybugs of the sea,” and you can see why. Their black spotted bodies and insect-like features make them look like an otherworldly version of the common winged beetles. “It required a lot of patience and precision to compose and light the shot properly,” Ivanov said. “In total, it took me six dives to get the shot I wanted. The result reveals an intimate glimpse of underwater life that is often overlooked.

  • Marine Biologists Just Filmed a Shark Threesome, and It’s a Win for Science

    Springer Nature’s Journal of Ethology has just published a study on a threesome. Yes, that kind of threesome—and it’s being hailed as a win for marine conservation efforts.

    That’s because the lovers in this particular trio are leopard sharks. Hugo Lassauce, a marine biologist from the University of the Sunshine Coast, filmed two males and one female of the endangered species mating in the wild in a first-of-its-kind video, shedding light on their natural reproductive behaviors.

    “The Indo-Pacific Leopard shark (Stegostoma tigrinum), listed as endangered by the IUCN, has primarily been studied in captivity, with little information on its natural mating behaviors,” the researchers wrote in the study. “Here, we present the first documented observations of group copulation in free-living S. tigrinum, recorded at Abore Reef, New Caledonia.”

    A sharky threesome

    Leopard sharks, sometimes referred to as zebra sharks, live in coastal waters throughout the Indo-West Pacific region. As soon as Lassauce captured the video and swam back to his team’s boat, they all cheered. It’s difficult to witness sharks copulating in the wild in the first place, so you can only imagine how rare it is to spot endangered shark species mating and get the chance to film it.

    “While I was surveying this particular aggregation of leopard sharks, I spotted a female with two males grasping her pectoral fins on the sand below me,” Lassauce said in a university statement. “I told my colleague to take the boat away to avoid disturbance and I started waiting on the surface, looking down at the sharks almost motionless on the sea floor. I waited an hour, freezing in the water, but finally they started swimming up.”

    The male sharks then each mated with the female, one taking 63 seconds, the other 47. Talk about a quickie. The female then “swam away actively,” and the males, now lethargic, lay still on the seafloor. Besides the excitement of catching something rare on camera, the video carries significant implications for our understanding of the endangered species.

    “These findings provide novel insights into the species’ reproductive strategies and highlight the importance of identifying and protecting key mating habitats,” Lassauce and his colleagues wrote in the study. “Given the conservation concerns surrounding S. tigrinum, understanding these mating mechanisms and recognizing reproductive sites are crucial for effective species management.”

    Sharing is caring

    Christine Dudgeon, a co-author of the study and a marine ecologist also from the University of the Sunshine Coast, explained in the statement that the video could also support artificial insemination research working to rewild leopard sharks.

    “It’s surprising and fascinating that two males were involved sequentially on this occasion,” she added.

    It would seem like leopard shark males are more willing to share their lovers than other species.

  • These Newly Discovered Deep-Sea Snailfish Just Became Our Latest Obsession

    The deep sea is home to some of the weirdest creatures on Earth, from ghostly elder fish to carnivorous harp sponges. Sometimes, scientists discover more humble creatures that are so tiny that they go unnoticed until new technology brings them into view.

    Such efforts rarely disappoint. Using an underwater robot camera, researchers discovered three new species of deep-sea snailfish: one bumpy, one dark, and one sleek. In a new paper published in Ichthyology and Herpetology, researchers explain how CT scans and DNA sequencing revealed that the three fish had features unlike any other known species, confirming their novelty.

    “Our discovery of not one, but three, new species of snailfishes is a reminder of how much we have yet to learn about life on Earth and of the power of curiosity and exploration,” Mackenzie Gerringer, study lead author and a marine scientist at SUNY Geneseo, said in a statement.

    Some complimentary snailfish trivia

    Snailfish are charming yet funky creatures. Although features vary among the 400 known species, they’re typically small, tadpole-shaped, and sport large, jelly-like heads. A disk on their belly allows them to either stick to the seafloor or “hitchhike on larger animals,” according to the Monterey Bay Aquarium Research Institute (MBARI).

    “They come in beautiful colors,” Johanna Weston, an ecologist at Woods Hole Oceanographic Institution not involved in the new work, told the New York Times. “They also have a lovely little smile on their face.”

    Snailfish that live in shallow waters will curl up against rocks or seaweed like snails, like their namesake. Snailfish in deep-sea trenches, on the other hand, are trickier to find, although a snailfish holds the record for the deepest-dwelling fish.

    Meet the new snailfish

    All three species were first discovered in 2019 over two expeditions off the coast of Central California. MBARI’s underwater robot explorer found the bumpy snailfish swimming at a depth of 10,722 feet (3,268 meters). The dark and sleek snailfish, on the other hand, swam even deeper, at about 13,451 feet (4,100 meters). The robot captured one of each species, carefully bringing them back to the lab for analysis.

    The bumpy snailfish (Careproctus colliculi) is pink and round but bumpy all around, whereas the dark snailfish (Careproctus yanceyi) is fully black with a round head and horizontal mouth. Unlike these two, the sleek snailfish (Paraliparis em) has a long, “laterally compressed body” and an angled jaw.

    Scientists aren’t sure yet how common these species are, but so far it appears that the bumpy snailfish may be the rarest. This particular encounter with the bumpy snailfish is the only confirmed observation of the species, the researchers said. The intention is to continue searching for more to understand these species’ geographic distribution. Hopefully, this won’t be the last time we meet these creatures.

  • Nearly Every Whale Shark at This Tourist Destination Bears Human-Made Scars

    The world’s largest living fish has plenty to fear from people. New research shows that a large proportion of whale sharks at a popular and protected tourism region bear scars caused by human activity.

    A large group of marine scientists examined more than a decade’s worth of whale shark sightings in the Bird’s Head Seascape off Indonesia. Among other things, they found that over half of the sharks had injuries attributable to humans. Many of these injuries were preventable, the researchers say, and simple measures can be taken to ensure the safety of these gentle giants moving forward.

    “[The] high percentage of injured whale sharks shows that even in protected zones, the whale shark interactions with fishing gear and tourism still pose risks to them,” study author Edy Setyawan, lead conservation scientist at the Elasmobranch Institute Indonesia, told Gizmodo.

    An endangered giant

    Befitting its nickname, the whale shark (Rhincodon typus) is certainly hefty.

    As adults, they commonly reach lengths between 30 and 40 feet (9 and 12 meters) and usually weigh around 18 tons; some get even larger. Despite their size, though, they’re no ferocious sea monster. These slow-moving fish are filter feeders that suck up their meals from the surrounding water. Though they can eat large and small marine organisms alike, they typically stick to microscopic plankton.

    Whale sharks can be found in warm and tropical waters all over the world, but their numbers have dwindled dramatically in recent decades, and they’re classified as an endangered species. They face several human-made threats, including hunting, climate change, and bycatching (being unintentionally caught by fishing boats). And even with ongoing conservation efforts, their recovery has been slow, partly because it can take up to 30 years for the sharks to reach sexual maturity.

    Common but avoidable harm

    According to Edy Setyawan, previous studies looking at the population health of these sharks have been limited to short-term surveys or snapshots of a single location. In their new research, the team was able to analyze 13 years of sightings along the Bird’s Head Seascape (2010 to 2023) from four regions of the area.

    The seascape is well known for its diversity and is estimated to contain three-quarters of the world’s coral species along with many other migrating species like the whale shark. The seascape is a popular destination for marine tourism and is covered by a network of 26 different Marine Protected Areas.

    Though the researchers largely studied past data they themselves collected, they also relied on photos captured by tourism operators and citizen scientists. All told, they identified 268 unique whale sharks. Roughly 200 of these sharks sported visible injuries, they found. And of these, 80% had injuries determined to be human-caused (58.3% had injuries from natural causes, while some sharks had both).

    On the positive side, severe injuries, including amputation, caused by humans were relatively rare (17.7%). The most common human-associated injuries were caused by sharks colliding into boats and bagans—floating platforms adorned with nets and lights used for fishing.

    The team’s findings were published Thursday in Frontiers in Marine Science.

    Fishing and marine tourism are important parts of the local economy, including whale shark sighting tours. And while the increasing popularity of these tours could lead to more injured sharks, the researchers argue this doesn’t have to be inevitable.

    They lay out simple steps that can greatly cut down on whale shark injuries, such as stricter regulations that would compel bagan fishers and owners to remove the sharp edges from their platforms. Tourism-related measures, like limiting boat traffic, enforcing slow-speed zones, and promoting responsible diving and snorkeling practices, would further reduce harm, Setyawan said.

    Not all the team’s findings are dire. They’ve learned a lot about these majestic aquatic beasts, including the main regions they reside within the seascape. Most of the sharks found there were also young juvenile males, suggesting the area is an important nursery habitat for the species.

    They next plan to track the annual population trends of whale sharks living in the seascape via satellite tags, which should also help them answer important questions like whether these populations migrate elsewhere.

  • Small changes bring big worries to lobster industry

    Small changes bring big worries to lobster industry

    Gerry Cushman has seen New England’s iconic lobster industry survive numerous threats in his three decades on the water, but the latest challenge — which might sound tiny — could be the biggest one yet.

    Lobster fishing is a game of inches, and the number of inches is about to change. Fishing regulators are instituting a new rule that lobster fishermen must abide by stricter minimum sizes for crustaceans they harvest.

    The change might be only 1/16th of an inch or 1.6 millimeters, but it will make a huge difference for fishermen when the fishery is already facing major threats from climate change and new rules designed to protect whales, numerous lobster fishers told The Associated Press.

    Interstate fishery regulators, however, say the change is necessary to preserve the future of the lobster population off New England as the species shifts farther north with warming waters.

    “The gauge increase and the vent increase is too much of a knee-jerk reaction,” said Marblehead resident Chris Chadwick of F/V Native Son II who fishes out of Gloucester due to the consolidation of the groundfishery in the region.

    “Just because farmers had a flood and they had a bad year, doesn’t predict all future outcomes,” the captain said of a drop in catch in recent years. “So a knee jerk reaction to this; it’s been in place for 30 years. We’ve seen ups. We’ve seen downs. We’ve seen hurricanes.

    “We’ve seen not as much rain. We’ve seen too much rain. We’ve seen all sorts … It runs the gamut so what’s in place I think is good, meaning leaving the gauge alone and leaving the vent alone.”

    The gauge is the tool used to measure lobster’s carapace. The vent size refers to is the size of the escape vent required in lobster traps appropriate to minimize the catch of sub-legal lobsters.

    Chadwick objects to both measurement increases.

    “You are going to be able to work your rear-end off, bait them, set them, chase them, but you are not going to be able to retain them through the vent increase and the gauge increase,” he said.

    “It’s better to keep it the same. All your metrics will be better. You can maybe estimate the future or reduce, but as a businessman, if you chase something you can’t retain, you are going to go out of business.”

    China, Canada trade

    In addition to causing a dispute between fishermen and regulators, the change has led to confusion about the ramifications for international trade of one of the world’s most popular seafoods.

    “We don’t need any more, really, on our plate. It’s just a lot going on, one fight after another,” Cushman, 55, a boat captain who fishes out of Port Clyde, Maine, said. “We don’t need anything in the marketplace to lower the price of lobsters.”

    Fishermen are pushing back at the new rules slated to go into effect next summer, because they fear even such a small change could dramatically alter their ability to fish. They also say it would put them at a competitive disadvantage with Canada, which harvests the same lobster species and has more relaxed rules. Some worry the size change could glut the market with lobsters in future years.

    “The Massachusetts Lobstermen’s Association DID NOT support Addendum 27 as it was presented as being a one-size-fits-all management plan,” Massachusetts Lobstermen’s Association Executive Director Beth Casoni said in an email to the Times.

    “The Lobster Management Areas 1, 3 and, Outer Cape Cod will all be greatly impacted by these biological measures.”

    Warming gulf, declining stock

    Recent surveys have shown a decline in baby lobsters off Maine, and regulators with the Atlantic States Marine Fisheries Commission say that could foreshadow a decline in catch.

    “We’re seeing a decline in recruits that will probably result in a decline in adults later on,” said Caitlin Starks, a senior fishery management plan coordinator with the commission.

    America’s lobster catch is already dipping — the haul in Maine, which harvests most U.S. lobster, fell from a high of 132.6 million pounds in 2016 to 93.7 million last year.

    Massachusetts is the second-largest lander of lobster in the U.S. behind Maine and Gloucester is the top Massachusetts port for landings. Bay State lobster fishers landed 15.8 million pounds of lobster last year, compared to 17.7 million pounds in 2016, according to a March 4 report in the Gloucester Times.

    The minimum size change applies to the Gulf of Maine, a piece of ocean off New England that’s one of the most important lobster fishing grounds in the world. Under commission rules, the legal harvesting size for lobsters would change there if the young lobster stock in the gulf dropped by 35%.

    Officials said last year the stock declined by 39% when comparing 2020-22 to 2016-18. That surprised both regulators and fishermen, and led many fishermen to question the accuracy of the commission’s data.

    Nonetheless, regulators say the minimum size on the gauges fishermen use to measure lobsters will increase to 3 5/16 inches (8.4 centimeters) on July 1, 2025, and grow another 1/16th of an inch two years later.

    Some conservationists support the changes, which they believe will protect lobsters from overfishing. That’s especially important “in the face of unprecedented climate change in the Gulf of Maine,” said Erica Fuller, an attorney in the ocean program at Conservation Law Foundation.

    Scientists say the gulf is warming faster than most of the world’s oceans.

    “Analysis shows that the proposed increase in gauge size will contribute to the long-term health and resiliency of the lobster stock by increasing its spawning stock biomass,” Fuller said.

    Industry consolidation?

    The changes do not apply in Canada, which has an even larger lobster fishing industry than the U.S. Some fishing grounds there already allow smaller lobsters to be caught than U.S. rules allow.

    Canadian authorities and trade groups are closely watching regulatory actions in the U.S.

    This month, the Atlantic States commission approved new rules to prevent the U.S. from importing sub-legal lobsters from Canada. The Canadian government is “committed to working with the Canadian fishing industry to help ensure continued market access,” Fisheries and Oceans Canada spokesman Barre Campbell said.

    Chadwick was concerned the new rules would lead to the same consolidation of the lobster fishery as has happened to the groundfish fishery in Gloucester due to tight restrictions.

    “The government thinks it’s better that we import haddock from Norway and Iceland and have them do the dirty work rather than employ Americans,” he said. “And, what’s going to happen is Canada is going to do the dirty work.

    “We are going to employ them and our fishermen are going to go out of business because we are going to have Canada do the lobstering for us.”

    Inability to sell lobsters to the U.S. could result in Canadians relying more on other foreign markets, said Geoff Irvine, executive director of the Lobster Council of Canada. China is a major buyer from both countries.

    “If we can’t sell those percentages of that size lobsters to the U.S. anymore, we have to find places to sell it,” Irvine said. “What does that mean for prices, what does that mean for harvesters?”

    Measure delayed to 2025

    The changes will likely have a major effect on the lobster industry, but might not trickle down to U.S. consumers, said John Sackton, a longtime seafood industry analyst. Prices this summer have been down compared to recent years, according to trade data. Whether that continues depends in part on how large the catch is for the rest of the year, he said.

    Some scientists who study the fishery have supported the minimum size change. Richard Wahle, a retired University of Maine marine sciences professor who has studied lobsters for decades, called it a “prudent” measure to protect the fishery’s future.

    But the lobster industry sees a different story, said Patrice McCarron, executive director of the Maine Lobstermen’s Association, the oldest and largest fishing industry association on the East Coast. The association believes the action isn’t needed at this time.

    Casoni said the Massachusetts Lobstermen’s Association “strongly believes that the overall impact of the 650 commercial lobstermen fishing in LMA 1, and OCC in Massachusetts is marginal on the resource and more data sets are needed to truly understand where the negative impacts are on the resource are coming from.

    “The MLA,” she said, “is cautiously encouraged as the Atlantic States Marine Fisheries Commission Lobster Board voted on and passed the creation of (an addendum) to delay the implementation of the biological measures under Addendum 27 until July 1, 2025.”

    The majority of material in the report came from Patrick Whittle of The Associated Press. Staff writer Ethan Forman contributed to this report.

  • She’s (hump)back

    She’s (hump)back

    SWAMPSCOTT — The same dead whale that washed ashore in Marblehead nearly three weeks ago is back — this time in Swampscott.

    Swampscott Animal Control Officer Scott Considine said Tuesday that the whale washed ashore on Phillips Beach, about 200-300 yards from where it had landed on Preston Beach in Marblehead on April 25.

    “I don’t think anybody expected this,” Considine said.

    The whale, a female young adult humpback weighing about 65,000 pounds, had been towed off Preston Beach and attached to a mooring on April 27. On May 2, the whale was towed to an area about 15 miles east of Stellwagen Bank National Marine Sanctuary, according to Andrea Gomez, a spokesperson for NOAA Fisheries. Stellwagen Sanctuary is a federally protected marine sanctuary at the mouth of Massachusetts Bay between Cape Ann and Cape Cod.

    Gomez said in an email that the release location was chosen to minimize the possibility of the carcass coming back to shore, and that NOAA created a “set and drift plan” to make sure that it didn’t.

    “The whale did not decompose as quickly as expected, however,” Gomez said.

    Gomez said the whale, which had been equipped with a satellite tag, was observed off Marblehead before landing in Swampscott.

    Gomez said Swampscott town officials, the Massachusetts Environmental Police, NOAA and the Environmental Protection Agency are working to develop another disposal plan for the whale.

    Considine, who was attaching a new tracking device to the whale on Tuesday morning, said the whale had “a couple of good-sized bites, and if we could flip her over I’m sure there’s tons of bites under there.”

  • WTF Fun Fact 13711 – Whales Evolved from Wolves

    WTF Fun Fact 13711 – Whales Evolved from Wolves

    When we received a fun fact submission suggesting that whales evolved from wolves, we were pretty skeptical. After all, we’ve taken evolutionary biology at the collegiate level—we’re smart people—and that just sounds silly.

    Well, so much for that confidence! Researchers believe they really have found proof of this mind-boggling evolutionary relationship.

    But whales’ journey from land to sea is one of evolution’s most astonishing tales. This transition didn’t happen overnight. It involved millions of years, with ancient wolf-like creatures at its inception. Today’s whales, creatures of the ocean’s vast expanses, share a lineage with terrestrial mammals. Their story of evolution is a testament to nature’s adaptability and the intricate pathways of evolutionary change.

    From Land to Sea

    The story starts around 50 million years ago. Imagine a time when the ancestors of whales roamed the earth on four legs. These ancient mammals, resembling wolves, embarked on a journey that would lead them to become the ocean’s giants. The first step in this transformation was a shift in habitat. Early ancestors, known as Pakicetus, lived near water bodies. They gradually ventured into the water for food, driven by survival needs and the abundance of aquatic prey.

    As these mammals spent more time in water, natural selection favored traits beneficial for aquatic life. Over millions of years, their body shape began to change. Limbs transformed into flippers, tails became powerful propellers, and their snouts extended to better catch fish. This gradual morphing wasn’t just physical. Changes occurred internally, too, such as the development of a mechanism to drink seawater, filtering out the salt, and adjustments in reproductive behavior to give birth in water.

    How Whales Evolved from Wolves

    The transformation from land-dwelling to fully aquatic life forms was marked by significant evolutionary milestones. The development of echolocation allowed whales to navigate and hunt in the deep, dark waters of the oceans. Their lungs adapted to allow them to dive deep and stay underwater for extended periods. These adaptations were crucial for survival and exploiting new ecological niches.

    One of the most pivotal moments in whale evolution was the emergence of two distinct groups: baleen and toothed whales. Baleen whales, like the blue whale, evolved a unique feeding mechanism using baleen plates to filter small fish and krill from the water. Toothed whales, including orcas and dolphins, pursued a different evolutionary path, focusing on hunting larger prey.

    The Legacy of Land-Dwelling Ancestors

    Despite their fully aquatic lifestyle, whales retain remnants of their land-dwelling past. Vestigial structures, such as hip bones, hint at their four-legged ancestors. Even their breathing reminds us of their terrestrial origins, as they must come to the surface to breathe air.

    The journey from wolf-like creatures to the majestic whales of today is a profound example of evolutionary adaptation. It underscores the dynamic nature of life on Earth and the constant drive for survival that shapes all living beings. Whales’ evolution from land to sea is not just a story of change but a narrative of resilience, innovation, and the enduring bond between all creatures of our planet.

  • Lawmakers seek to lift fishing gear removal ban

    Lawmakers seek to lift fishing gear removal ban

    BOSTON — A new bipartisan proposal calls for lifting a statewide ban on removing abandoned fishing lines to help protect critically endangered North Atlantic right whales.

    The legislation, filed by Senate Minority Leader Bruce Tarr, R-Gloucester, would authorize the state Division of Marine Fisheries – with the approval of the Marine Fisheries Advisory Commission and the Department of Fish and Game – to set regulations allowing for the removal of fishing gear from state waters.

    Under current law, commercial fishing gear is considered private property and cannot be removed when it becomes dislodged and sinks to the ocean floor or washes up on shore. Backers of the plan say abandoned fishing gear poses a threat to the marine environment and ecosystems.

    “It ‘ghost fishes,’ increasing mortality without any harvest benefit, it presents a major risk for entanglement for right whales and other species, it clutters and pollutes the ocean floor, and it presents ongoing problems for coastal communities that have to deal with this form of pollution when it washes ashore and must be collected and disposed of before it does further damage,” Tarr said in a statement.

    The rare bipartisan measure is co-sponsored by more than a dozen lawmakers spanning the North Shore, South Shore, Cape Cod and the islands, including state Sen. Joan Lovely, D-Salem, and Rep. Ann-Margaret Ferrante, D-Gloucester, and House Minority Leader Brad Jones, R-North Reading.

    It’s also backed by the Massachusetts Lobstermen’s Association, which lauded the fact that the bill would allow abandoned gear to be collected during community beach cleanups.

    “The commercial lobster industry also helps with many of these cleanup efforts to maintain clean beaches for everyone to enjoy,” said Beth Casoni, the association’s executive director. “We look forward to seeing this bill through to the end.”

    The bill also includes protections for fishermen, including a provision that clarifies it is unlawful to “take, use, destroy, injure or molest” traps, lines and other gear “without the consent of the owner.”

    Lawmakers say the proposal seeks to strike a balance between the protection of right whales while recognizing the impact of government-ordered fishing ground closures and other restrictions on the state’s commercial lobster fishery.

    Driven to the brink of extinction in the 20th century by whalers, North Atlantic right whales are more recently at risk from ship collisions and entanglement in fishing gear.

    Scientists say the population of North Atlantic right whales has dwindled to about 360. The species has also been hindered by poor reproduction and several years of high mortality, research has shown.

    Environmental activists want to ban commercial fishing nets and gear in state waters to prevent entanglements of whales and turtles. They’ve also called for federal regulators to expand no-fishing zones and mandate the use of so-called “ropeless” fishing gear to reduce the risk of entanglements.

    Federal regulators are considering new regulations requiring modifications in fishing gear to help reduce whale fatalities, but those rules have been put on hold for two years following recent court challenges.

    Massachusetts lobstermen argue that they’re doing more than enough to protect the whales by following conservation measures, including a months-long fishing closure during the winter and early spring and the use of new technology.

    They also argue that line entanglements are rare and say additional regulations would mean more financial pressures for an industry that is already struggling amid stringent regulations and closures of fishing areas.

    Last week, the National Oceanic and Atmospheric Administration announced the death of a right whale off Martha’s Vineyard from a fishing line entanglement.

    The federal agency said the fishing gear, which had become deeply embedded in the whale’s tail, was traced back to Maine’s commercial lobster industry.

    Meanwhile, authorities discovered another dead right whale carcass floating off the coast of Georgia this week.

    The deaths have rekindled demands from environmental groups to impose new restrictions on fishing gear and commercial vessels to protect the critically endangered species.

    “The death of two juvenile North Atlantic whales within three weeks of each other is heartbreaking and preventable,” Kathleen Collins, senior marine campaign manager for the International Fund for Animal Welfare, said in a statement Thursday. “The right whale graveyard off our eastern seaboard continues to grow and inaction from the administration is digging the graves.”

    First-ever image of a newborn great white shark revealed


    For the first time, a live baby great white shark has been spotted in the wild.

    The shark was around 5 feet long already and pure white, unlike its grey-colored adult counterparts, leading scientists to believe it could be a baby great white, according to a new paper discussing the finding in the journal Environmental Biology of Fishes.

    Great white sharks, known to scientists as white sharks, have never before been observed as juveniles, with their mating and reproduction being a long-standing mystery to marine biologists.

    “Where white sharks give birth is one of the holy grails of shark science. No one has ever been able to pinpoint where they are born, nor has anyone seen a newborn baby shark alive,” wildlife filmmaker Carlos Gauna, who was one of the pair that spotted the shark, said in a statement. “There have been dead white sharks found inside deceased pregnant mothers. But nothing like this.”

    A newborn great white shark filmed off the California coast near Santa Barbara. This may be the first-ever observation of a newborn great white.

    The baby shark was sighted off the coast of Santa Barbara, California, on July 9, 2023, by Guana and Phillip Sternes, a UC Riverside biology doctoral student, who captured the rare occurrence on a drone camera.

    “We enlarged the images, put them in slow motion, and realized the white layer was being shed from the body as it was swimming,” Sternes said in the statement. “I believe it was a newborn white shark shedding its embryonic layer.”

    Great white sharks can grow to lengths of 16 feet and are listed as “vulnerable” worldwide and “critically endangered” in Europe on the IUCN Red List. These sharks give birth to live young, with the shark fetuses feeding on a sort of “milk” within their mothers’ wombs. This is what the researchers believe they saw surrounding the shark pup, giving it the white color.

    “I believe what we saw was the baby shedding the intrauterine milk,” Sternes said.

    The size and shape of the white-colored shark is around what would be expected for a newborn great white.

    “In my opinion, this one was likely hours, maybe one day old at most,” Sternes said.

    Another piece of evidence supporting this shark being a juvenile is the location: pregnant sharks had previously been observed in the same area, indicating that this may be a popular spot for the sharks to give birth.

    “I filmed three very large sharks that appeared pregnant at this specific location in the days prior. On this day, one of them dove down, and not long afterwards, this fully white shark appears,” Gauna said. “It’s not a stretch to deduce where the baby came from.”

    It was previously thought that great whites gave birth further out to sea, but this juvenile was spotted only around 1,000 feet from land, indicating that they may instead give birth in shallow waters. This area may, therefore, be a contender for research into great white shark reproduction and birth.

    “There are a lot of hypothetical areas, but despite intense interest in these sharks, no one’s seen a birth or a newborn pup in the wild,” Sternes said. “This may well be the first evidence we have of a pup in the wild, making this a definitive birthing location.”

    In the paper, the authors note that it is possible that the shark’s white color may not be because it was a juvenile but instead due to a skin condition of some form. However, they are fairly certain that it was indeed a newborn great white.

    “If that is what we saw, then that too is monumental because no such condition has ever been reported for these sharks,” Gauna said.

    “Further research is needed to confirm these waters are indeed a great white breeding ground. But if it does, we would want lawmakers to step in and protect these waters to help white sharks keep thriving,” Sternes said.
