Endangered fin whale and calf sighting is a “rare occurrence,” New England Aquarium scientist says

August 7, 2025 — New England Aquarium researchers recently documented what they say was a rare sighting of an endangered fin whale and its calf.

Scientists on a July 24 aerial survey flew over the Northeast Canyons and Seamounts Marine National Monument, about 130 miles southeast of Cape Cod. They observed more than 1,000 marine animals, including seven fin whales, one endangered sperm whale, one humpback whale, two minke whales and more than 900 dolphins.

“Seeing an endangered fin whale and its calf is a rare occurrence,” assistant research scientist Kate Laemmle said in a statement Wednesday.

Microplastic pollution is everywhere, even in the exhaled breath of dolphins – new research

October 17, 2024 — Bottlenose dolphins in Sarasota Bay in Florida and Barataria Bay in Louisiana are exhaling microplastic fibers, according to our new research published in the journal PLOS One.

Tiny plastic pieces have spread all over the planet – on land, in the air and even in clouds. An estimated 170 trillion bits of microplastic are estimated to be in the oceans alone. Across the globe, research has found people and wildlife are exposed to microplastics mainly through eating and drinking, but also through breathing.

Our study found the microplastic particles exhaled by bottlenose dolphins (Tursiops truncatus) are similar in chemical composition to those identified in human lungs. Whether dolphins are exposed to more of these pollutants than people are is not yet known.

Why it matters

In humans, inhaled microplastics can cause lung inflammation, which can lead to problems including tissue damage, excess mucus, pneumonia, bronchitis, scarring and possibly cancer. Since dolphins and humans inhale similar plastic particles, dolphins may be at risk for the same lung problems.

Conservation groups call on US to ban foreign seafood over whale and dolphin bycatch

December 8, 2023 — Conservation groups want NOAA Fisheries to ban imports from foreign fisheries that are not adequately working to prevent marine mammal bycatch.

“By continuing to allow imports that do not meet U.S. standards, [NOAA Fisheries] NMFS chooses business as usual over the survival of some of the most amazing species on the planet,” Natural Resources Defense Council (NRDC) Senior Attorney and Global Biodiversity Conservation Director Zak Smith said. “Because NMFS has failed to safeguard ocean biodiversity, future generations may never have the chance to protect invaluable marine life.”

River Traps Chew at Huge Ocean Plastics Problem

June 16, 2022 — Floating fences in India. Whimsical water- and solar-driven conveyor belts with googly eyes in Baltimore. Rechargeable aquatic drones and a bubble barrier in The Netherlands.

These are some of the sophisticated and at times low-tech inventions being deployed to capture plastic trash in rivers and streams before it can pollute the world’s oceans.

The devices are fledgling attempts to dent an estimated 8.8 million tons (8 metric tons) of plastic that gets into the ocean every year. Once there, it maims or kills marine plants and animals including whales,dolphins, and seabirds and accumulates in the Great Pacific Garbage Patch and other vast swirls of currents.

Trash-gobbling traps on rivers and other waterways won’t eliminate ocean plastic but can help reduce it, say officials with the National Oceanic and Atmospheric Administration’s Marine Debris Program.

Infectious disease found in Hawaiʻi dolphin could spark mass marine mammal deaths

August 9, 2021 — After two years of investigating the cause of death of a Fraser’s dolphin that was stranded on Maui in 2018, researchers discovered a novel strain of morbillivirus, a marine mammal disease responsible for deadly outbreaks among dolphins and whales worldwide. The University of Hawaiʻi at Mānoa Health and Stranding Lab conducted the necropsy (an animal autopsy) and published the report of the morbillivirus discovery in Nature Scientific Reports. It is the first linked to this dolphin species.

“The 2018 stranding of the Fraser’s dolphin revealed that we have a novel and very divergent strain of morbillivirus here in Hawaiian waters that we were previously unaware of,” said Kristi West, associate researcher at UH Mānoa’s Hawaiʻi Institute of Marine Biology who directs the Health and Stranding Lab. “Morbillivirus is an infectious disease that has been responsible for mass mortalities of dolphins and whales worldwide. It is related to human measles and smallpox.”

The discovery led to a suite of independent tests (immunohistochemistry, culturing of the virus and transmission electron microscopy) to confirm the finding and understand the role of this distinct morbillivirus in the pathology of the Fraser’s dolphin. The UH Health and Stranding Lab only recovers less than 5% of the dolphins and whales that die in Hawaiian waters, which makes detecting disease outbreaks very difficult.

Experts Collaborate on Mission to Document Protected Species

July 19, 2021 — The following was released by NOAA Fisheries:

Scientists from NOAA’s Southeast Fisheries Science Center recently completed the first leg of a mission to survey marine mammals and other protected species in waters off the southeast coast of the United States. They are locating, identifying, and counting marine mammals from both the NOAA Ship Gordon Gunter and a NOAA Twin Otter aircraft.

The data they collect will be used to assess the abundance, distribution, ecology, and behavior of marine mammals, sea turtles, and seabirds throughout the U.S. Atlantic. These data are also critical for updating the Atlantic stock assessment reports required by the Marine Mammal Protection Act (MMPA).

Usually, we conduct these marine mammal surveys annually but were not able to collect data in 2020 because of the COVID-19 pandemic. The beginning of this trip has also had some challenges—two tropical storms have made for rough seas and grounded flights.

In spite of these challenges, the ship-board team has logged 325 marine mammal sightings—a single leg record for the team—since departing Newport, Rhode Island on June 12 and arriving in Charleston, South Carolina on July 3. Notable sightings included two large Clymene dolphin (Stenella clymene) sightings, a Gervais’ beaked whale (Mesoplodon europaeus) sighting, and multiple false killer whale (Pseudorca crassidens) sightings. Scientists were also towing a hydrophone array to collect passive acoustic data—underwater sounds from whales and dolphins. They collected 76 recordings, 16 of which were from sperm whale groups.

Dolphin Safe group alleges ‘Seaspiracy’ left out critical details from executive’s interview

March 30, 2021 — An executive with the international organization responsible for the Dolphin Safe tuna label is charging that the producers of the new Netflix documentary “Seaspiracy” took his comments out of context to suggest dolphins are being slaughtered by tuna fishing operations.

Mark Palmer, associate director USA, for the International Marine Mammal Project (IMMP), which is operated by the Earth Island Institute, said he provided the documentary’s film crew with “extensive information on how the Dolphin Safe label is used for the protection of dolphins.”

None of this information was used in the documentary, he said in a post on the group’s website.

Palmer, in one of the more memorable scenes from the film, was asked if his group could guarantee that no dolphins were ever killed in any tuna fishery anywhere in the world.

SAFMC Chooses Preferred Management Measures for Dolphin and Wahoo Fisheries

March 5, 2021 — The following was released by the South Atlantic Fishery Management Council:

During its meeting this week, members of the South Atlantic Fishery Management Council chose preferred management alternatives affecting Dolphin and Wahoo harvested in federal waters along the entire Atlantic coast. The proposed measures, as outlined in Amendment 10 to the Dolphin Wahoo Fishery Management Plan, would reduce the current recreational vessel limit for Dolphin from 60 fish to 48 fish per vessel while maintaining the 10 fish per person/day bag limit and reduce the daily bag limit for Wahoo from 2 fish to 1 fish per person/day. Reductions in harvest are intended to help prevent seasonal closures that could be imposed should catch levels be exceeded.

Regional differences in the Dolphin and Wahoo fisheries became the focus of discussion as members of the Council reviewed concerns expressed during public hearings held in late January. Fishermen in South Florida and the Keys, including charter captains, have expressed concerns about catching fewer Dolphin and encountering smaller fish over the past few years and have requested the Council take action to reduce harvest. Further north, charter captains and other fishermen have raised objections to the proposed reductions, noting the importance of maintaining higher vessel limits for trips that require much farther runs offshore.

“We’ve heard from constituents and advisory panel members and believe their observations. Looking at the various management scenarios for both Dolphin and Wahoo, the Council compromised to reduce catches while addressing concerns of fishermen dependent on these valuable recreational fisheries,” explained Council Chair Mel Bell. “There are many variables affecting these migratory fisheries, including international harvest, environmental conditions, and other factors. We don’t have a clear sense of what the problem is and we’re being more preventative than curative at this point,” said Bell.

Amendment 10 also includes updates to annual catch limits, modifications to sector allocations, and changes to accountability measures designed to ensure the catch levels are not exceeded for both Dolphin and Wahoo. Proposed management measures would also allow properly permitted commercial fishing vessels with trap, pot or buoy gear onboard to retain up to 500 pounds (gutted weight) of Dolphin and remove the Operator Card requirement for for-hire and commercial fishermen in the Atlantic Dolphin Wahoo fishery. After considering recommendations from its advisory panels and public comment, the Council removed an action that would have allowed filleting Dolphin at sea on for-hire vessels in federal waters north of the NC/VA border. The Council is scheduled to approve Dolphin Wahoo Amendment 10 for review by the Secretary of Commerce during its June meeting.

Red Snapper
NOAA Fisheries provided an update on the recreational Red Snapper Season for 2021. Due to delays from COVID-19, some landings data from 2020 are not yet available. Those data are expected in May 2021. NOAA Fisheries intends to announce the 2021 season as soon as data are available and evaluated. If a season is allowed, the recreational season for Red Snapper begins on the second Friday in July. The number of fishing days is determined by NOAA Fisheries based on catch estimates from the previous season. The recreational season was open for four days in 2020 and five days in 2019.

A new stock assessment for Red Snapper will be reviewed by the Council’s Scientific and Statistical Committee (SSC) during its meeting in late April. The Council will receive an overview of the assessment and the SSC’s recommendations during its June meeting. The Council discussed management options for considering the stock assessment results in setting the 2021 catch levels and requested that staff determine if an abbreviated framework can be used to adjust catch levels and if so, prepare such an amendment for Council review at their June 2021 meeting. The Council will also move forward with a plan amendment to modify annual catch limits, allocations, and other management measures necessary as a result of the stock assessment.

King Mackerel, Red Porgy, Snowy Grouper and Rock Shrimp Fishery Access Area
The Council continued work on management measures addressing Atlantic migratory group King Mackerel to address the recent stock assessment update that found the stock is not overfished or undergoing overfishing. The measures, originally included in Framework Amendment 10 and now Amendment 34 to the Coastal Migratory Pelagics Fishery Management Plan, would modify annual catch limits and sector allocations, increase the recreational bag limit and possession limits off the coast of Florida, reduce the minimum size limits for both commercial and recreational sectors, and allow retention of “cut off” King and Spanish Mackerel by recreational fishermen as is allowed for the commercial sector. Public hearings on the amendment will be scheduled following the Council’s June meeting.

Proposed management measures for Red Porgy to end overfishing and rebuild the stock continued to be reviewed in Amendment 50 to the Snapper Grouper Fishery Management Plan, with public hearings scheduled this summer. The Council reviewed recent stock assessment results for Snowy Grouper and recommendations from its SSC and will begin developing an amendment to address management measures. The Council also approved Coral Amendment 10 for public hearings to be held prior to the Council’s June meeting. The amendment addresses a Shrimp Fishery Access Area for rock shrimp along the northern extension of the Oculina Bank Coral Habitat Area of Particular Concern off the east coast of Florida.

Additional information about this week’s meeting, including a meeting Story Map, committee reports, and briefing book materials is available from the Council’s website at: https://safmc.net/safmc-meetings/council-meetings/. The next meeting of the South Atlantic Fishery Management Council is currently scheduled for June 14-18, 2021 in Ponte Vedra, Florida.

11 Cool Cetaceans Facts

February 17, 2021 — The following was released by NOAA Fisheries:

Marine mammals in the cetacean family include whales, dolphins, and porpoises. These animals are often referred to as “sentinels” of ocean health, providing insight into marine ecosystem dynamics. Learn more cool things about cetaceans below.

1. They tend to be social and live in groups. Cetaceans may communicate by slapping the water.

Dolphins and porpoises exhibit complex communication and echolocation by making squeaks, buzzes, whistles, and clicks that can be heard from miles away. They are also thought to communicate by slapping the water’s surface with their tails or bodies.

2. Killer whales are part of the dolphin family. There are three main types of killer whales, or ecotypes, in the North Pacific: Resident, Transient, and Offshore.

In fact, they are the largest member of the Delphinidae, or dolphin family. Members of this family include all dolphin species, as well as other larger species such as long-finned pilot whales and false killer whales, whose common names also contain “whale” instead of “dolphin.”

Each North Pacific killer whale ecotype differs in appearance, diet, habitat, genetics, and behavior. While all three types share at least part of their habitats, they are not known to interbreed. Resident killer whales usually eat different varieties of fish, primarily salmon. Southern Resident killer whales prefer Chinook salmon, some of which are endangered. Transient (or Bigg’s) killer whales eat other marine mammals, such as seals, and squid. Offshore killer whales primarily eat sharks and scientists have discovered that the whales’ teeth are worn down over time due to sharks’ rough skin.

In January, 2019, an experienced group of killer whale biologists launched an expedition from the southern tip of Chile into some of the roughest waters in the world, searching for what could be a new species of killer whale.

3. Blue whales have the biggest hearts on the planet.

The heart of a blue whale weighs more than 1,000 pounds, the weight of an average dairy cow.

CAPITO, FEINSTEIN REINTRODUCE BILL TO PROTECT WHALES, DOLPHINS, SEA TURTLES FROM DRIFT GILLNETS

February 9, 2021 — The following was released by The Office of Senator Shelly Moore Capito (R-WV):

U.S. Senators Shelley Moore Capito (R-W.Va.) and Dianne Feinstein (D-Calif.), today reintroduced the Driftnet Modernization and Bycatch Reduction Act, a bipartisan bill to phase out harmful large mesh drift gillnets used in federal waters off the coast of California – the only place the nets are still used in the United States.

Large mesh drift gillnets, which are between a mile and a mile-and-a-half long and can extend 200 feet below the ocean surface, are left in the ocean overnight to catch swordfish and thresher sharks. However, at least 60 other marine species, including whales, dolphins, sea lions, sea turtles, fish and sharks, can also become entangled in the large mesh net “walls,” injuring or killing them. Most of these animals, referred to as bycatch, are then discarded. The use of large mesh drift gillnets by a single fishery based in California is responsible for 90 percent of the dolphins and porpoises killed along the West Coast and Alaska.

“While the use of driftnets is already prohibited off the coasts of most states, these tools are still injuring or killing a whole host of marine animals off California’s coast,” Senator Capito said. “I’m proud to reintroduce this bipartisan legislation that will help ensure large mesh driftnets are no longer used in any U.S. waters, protecting our marine wildlife from this harmful practice.”

“Let’s be clear: the Senate unanimously passed our bill and the House passed it shortly thereafter. There is no support to continue using these deadly nets in our waters,” Senator Feinstein said. “Large mesh driftnets indiscriminately kill whales, dolphins, porpoises, sea turtles and other marine animals. It’s time to transition the industry to more efficient, sustainable and profitable methods. Real-time data shows other fishing gear is more successful, profitable and sustainable. Now that we have a new administration, I’m hopeful that Congress will quickly pass our bill and we can begin to phase driftnets out.”

The bill would phase out the use of the nets and help the industry transition to more sustainable methods like deep-set buoy gear that uses a hook-and-buoy system. Deep-set buoy gear attracts swordfish with bait and alerts fishermen immediately when a bite is detected. Testing has shown that as much as 98 percent of animals caught with deep-set buoys are actually swordfish, resulting in far less bycatch than large mesh drift gillnets, which average a 50 percent catch rate of target species.

A seven-year study by the Pfleger Institute of Environmental Research found that fishing vessels using the new deep-set buoy gear caught 83 percent more swordfish than those using traditional large mesh drift gillnets. Also, because vessels are alerted as soon as there is a bite, swordfish are transported to markets faster than with large mesh drift gillnets, resulting in higher-quality products that bring a higher price.
