Births among endangered right whales highest since 2015

April 5, 2021 — North Atlantic right whales gave birth over the winter in greater numbers than scientists have seen since 2015, an encouraging sign for researchers who became alarmed three years ago when the critically endangered species produced no known offspring at all.

Survey teams spotted 17 newborn right whale calves swimming with their mothers offshore between Florida and North Carolina from December through March. One of those calves soon died after being hit a boat, a reminder of the high death rate for right whales that experts fear is outpacing births.

The overall calf count equals the combined total for the previous three years. That includes the dismal 2018 calving season, when scientists saw zero right whale births for the first time in three decades. Still, researchers say greater numbers are needed in the coming years for North Atlantic right whales to rebound from an estimated population that’s dwindled to about 360.

“What we are seeing is what we hope will be the beginning of an upward climb in calving that’s going to continue for the next few years,” said Clay George, a wildlife biologist who oversees right whale surveys for the Georgia Department of Natural Resources. “They need to be producing about two dozen calves per year for the population to stabilize and continue to grow again.”

Protecting right whales: Advocates, fishermen say proposal needs more work

March 1, 2021 — A fatal collision that killed a baby whale and injured his mother in waters south of Brunswick is the latest impetus for advocates of whales to respond by the March 1 deadline for public comments on proposed federal rules intended to protect right whales.

The infant and his mother, named Infinity, were struck Feb. 12, off St. Augustine Inlet, Fl. The captain of a 54-foot sport fishing vessel reported that he’d driven over a whale. The boat began taking on water and the captain grounded the boat to prevent her from sinking, according to a report by the Florida Fish and Wildlife Research Institute. No human injuries were reported.

The 22-foot-long carcass of the infant whale washed ashore at Anastasia State Park. The mother, known in scientific circles as Catalog #3230, was spotted off the coast of South Georgia on Feb. 16, with “two new cuts on her left side suggestive of a vessel strike,” according to a report from the Georgia Department of Natural Resources and Clearwater Marine Aquarium.

This incident helped fuel an attendance of more than 300 at last week’s virtual public hearing on the proposed revision of a federal regulation regarding the protection of whales from commercial fishing gear. Attention to the plight of right whales is increasing as their numbers dwindle. Fewer than 350 of the mammals are thought to exist, according to a report issued Wednesday by the New England Aquarium, which has studied right whales for 40 years.

Study finds human-caused North Atlantic right whale deaths are being undercounted

February 25, 2021 — A study co-authored by scientists at the New England Aquarium has found that known deaths of critically endangered North Atlantic right whales represent a fraction of the true death toll. This comes as the death of a calf and recent sightings of entangled right whales off the southeastern United States raise alarm.

The study, published this month in Conservation Science and Practice, analyzed cryptic mortality of right . Cryptic mortality refers to deaths resulting from human activities that do not result in an observed carcass. The study’s authors combined data on whale encounters, , serious injuries, and necropsies from the North Atlantic Right Whale Consortium Identification Database curated by the New England Aquarium with the serious injury and mortality database held by the National Marine Fisheries Service. The scientists concluded that known deaths of the critically  accounted for only 36% of all estimated death from 1990 to 2017.

“Our work has shown that 83% of identified right whales have been entangled one or more times in , and an increasing number of these events result in severe injuries or complex entanglements that the whales initially survive. But we know their health becomes compromised and they eventually succumb and sink upon death,” said Amy Knowlton, senior scientist with the Aquarium’s Anderson Cabot Center for Ocean Life.

‘Ropeless’ Lobster Fishing Could Save The Whales. Could It Kill The Industry?

February 22, 2021 — By using this technology, Martin eliminates the need to use vertical ropes which can be deadly for North Atlantic right whales diving for food. Rope entanglement is a leading cause of death for the mammals that can weigh as much as 70 tons. In fact, more than 85% of right whales have been entangled in fishing gear at least once, the majority multiple times, according to a report from the New England Aquarium.

Today, with an estimated 370 North Atlantic right whales remaining, the species is classified by the IUCN Red List as critically endangered, one step from extinction.

To save the whales from the brink, state authorities have instituted seasonal fishing closures in waters off New England. More protections from the National Atmospheric and Oceanic Administration, which some fishermen consider burdensome, are still pending.

Conservationists hope that fishermen like Rob Martin can prove ropeless fishing can save both the whales and the lobster industry.

Many lobstermen, though, say they prefer the closures to the technological leap they would have to make to adopt ropeless fishing.

Right whales enter a new year filled with uncertainty

December 22, 2020 — For North Atlantic right whales, the most endangered great whale — and marine mammal —  on Earth, the good news for the new year started early, with the birth of three calves in the fall.

But a fourth calf washed up dead on a North Carolina beach in late November, believed to have died of natural causes soon after birth.

For a species that now numbers 366 individuals with less than 100 females, the births were hailed as a sign that something at least was going right.

“One of the positives is that two of the three mothers are new mothers,” said Philip Hamilton, a research scientist at the New England Aquarium’s Anderson Cabot Center for Ocean Life. Hamilton oversees the Anderson center’s North Atlantic right whale photo-identification catalog.

After years where the numbers of calves fell below the number of dead whales lost to entanglement in fishing gear and collisions with ships, Hamilton found solace in these new mothers.

Lobstermen Raise Concerns Over Proposed Regulations to Protect Endangered Whales

December 10, 2020 — The state is asking for public feedback on new rules to protect critically endangered North Atlantic right whales from entanglement in fishing gear.

At a public hearing on Tuesday, the Massachusetts Department of Marine Fisheries (DMF) shared its recommendations to extend a seasonal commercial-gear closure to areas north and east of the Cape from February 1 through April 30.

Dan McKiernan, DMF director, also explained new requirements for vertical buoy lines that would mandate that they break apart when exposed to 1,700 pounds of pressure.

“A recent study by the New England Aquarium on whale entanglement showed ropes with low breaking strength can reduce serious injury and mortality by at least 72 percent,” he said.  “Cooperative research with commercial lobsterman has demonstrated that ropes of these breaking strength are strong enough in most cases to allow for the successful hauling of lobster gear.

“In essence,” he said, “this research and proposal tried to hit the sweet spot for a line that is safe for the industry and beneficial for right whales.”

Texas Organizations Help Cold-Stunned Sea Turtles from Massachusetts

December 8, 2020 — The following was released by NOAA Fisheries:

On Monday, December 7, 120 sea turtles flew south thanks to Turtles Fly Too. These sea turtles were found on Cape Cod, Massachusetts beaches suffering from hypothermia and other complications in recent weeks. They will continue to receive treatment and care from seven facilities in Texas.

Of the more than 500 cold-stunned sea turtles that have washed up so far this year, the vast majority are endangered Kemp’s ridleys. Green and loggerhead sea turtles have been rescued, as well. Mass Audubon’s Wellfleet Bay Wildlife Sanctuary responds to all of these cold-stunned turtles. They transport live turtles to two Massachusetts rehabilitation facilities: the New England Aquarium and the National Marine Life Center.

Sea turtles are cold-blooded and rely on heat from their environment to maintain their body temperatures. When water temperatures drop rapidly, they become lethargic and unable to swim due to the cold. Many of the turtles have pneumonia, and some have other medical conditions or injuries from being washed against rocks. They require expert care—but with so many turtles, the rehabilitation facilities are filling up. And it’s only early December. The cold-stun season usually lasts until late December or early January.
