NOAA research zeroes in on saving right whales

November 23, 2018 — Why is the endangered western North Atlantic right whale population growing far more slowly than those of southern right whales, a sister species also recovering from near extinction by commercial whaling?

NOAA Fisheries researchers and colleagues looked more closely at the question and have concluded that preserving the lives of adult females in the population is by far the most effective way to promote population growth and recovery.

North Atlantic right whales are frequently seen in the waters off the Cape, and most deaths are attributed to entanglement in fishing gear and collisions with ships, says NOAA.

Eighty-three percent of all individual North Atlantic right whales have been entangled in fishing gear at least once in their lives, and 59 percent have been entangled two or more times, the research found.

The energy demands from the drag associated with entanglement can reduce the likelihood that a female can successfully reproduce.

Years between births also increases for females, given the recovery period needed from the physical costs of entanglements, which can last from months to years.

Ropeless fishing options floated

November 15, 2018 — Whales and fishing gear increasingly occupy the same areas of ocean in the Gulf of Maine, and whales being injured or killed by entanglement with gear continues to be a top concern of scientists and regulators.

While most Maine lobstermen say they have never even seen a right whale close to the Maine coast, statistics collected by NOAA explain why right whales are exposed to a high risk of entanglement off the Maine coast.

Based on data collected by the Atlantic States Marine Fisheries Commission, there are some 2.9 million lobster traps in the water within 50 miles of the Maine coast. Even with an average of fewer than five whales per month passing through Maine waters, the density of gear makes the risk of entanglement very high.

Last week, scientists and other interested parties met for a day-long meeting on one idea they hope will reduce entanglements: ropeless fishing. The Ropeless Consortium meeting was held Nov. 6, the day before the annual meeting of the North Atlantic Right Whale Consortium (NARWC) at the New Bedford Whaling Museum. The meeting was closed to the press, but an agenda and overview of the meeting was available online.

“It was very cool to see how advanced the technology is and the many companies and groups working on development around the world,” said Zack Klyver, lead naturalist for Bar Harbor Whale Watch, who attended the meeting. “The conservation community were excited about the idea that this could be a long-term 100 percent fix to all whale entanglement.”

Industry, agencies working to avoid whale entanglements

November 14, 2018 — LONG BEACH, Calif. — Whale entanglements off the West Coast and potential solutions to the escalating problem are the focus of a new report including the presentations and observations of fishermen, biologists and fisheries managers who gathered at an August workshop.

In recent years, growing populations of humpback and gray whales, changing ocean conditions and prey locations, and later crab season openings have led to more whales getting entangled in fishing gear, such as the ropes and floats that mark the location of crab pots. In 2017 there were 31 confirmed entanglements off the West Coast, including two humpbacks and a gray whale off the Washington coast, according to a press release from NOAA Fisheries. While NOAA concedes these entanglements are still proportionally rare, they sometimes lead to the deaths of entangled whales, so both fishermen and fisheries managers are seeking solutions.

To understand how and where rope and other gear entangles whales and to find ways to address the problem, the Pacific States Marine Fisheries Commission (PSMFC) and NOAA Fisheries’ West Coast Region convened a two-day workshop in Long Beach, California, in August. This “forensic workshop” was also supported by The Marine Mammal Commission, Oregon Sea Grant, and the Aquarium of the Pacific. The report from the workshop is now available at tinyurl.com/whale-entanglement-report.

The report provides the notes and presentations from the 31 California, Oregon, and Washington experts who attended. Participating were Dungeness crab fishermen; gear specialists; marine mammal biologists and disentanglement specialists; conservation groups; and federal, tribal and state agency representatives.

Fisherman Risks His Life to Save a Humpback Whale

November 14, 2018 — As they headed back toward the central California coast after fishing for slime eel in the Pacific Ocean, Sam Synstelien and Nicholas Taron made a troubling discovery: a humpback whale was entangled in a buoy’s rope, frantically trying to free itself.

Synstelien immediately called the U.S. Coast Guard but was told it might take a few hours for someone to get there. The two commercial fishermen thought that could be too long for the whale to survive its predicament.

“(The whale) was just swimming in counter-clockwise circles,” Taron told NBC Bay Area. “You could tell he was stressed and being held to the bottom.”

Instead of waiting for the Coast Guard or leaving the whale behind, Synstelien and Taron decided to try to save its life. They cranked up the volume on the radio of their 27-foot-long boat (aptly named “Persistence”) and shouted into the microphone to get the frantic, 40-foot-long humpback’s attention.

“We were screaming at the whale, ‘You’re either going to help us out and quit swimming away or else, like, good luck,’” Taron said.

The two were able to cut through the rope wound around the whale’s tail, but the rope still entangled its midsection. Synstelien decided to try to free it himself. As Taron recorded a video on his cell phone, Synstelien jumped onto the whale and shimmied up its back.

Less whale tours, dams: Washington task force returns with guidance on Tuesday

November 13, 2018 — Gov. Jay Inslee first assembled the group in March, inviting representatives from tribal, federal, local and other state governments, as well the private and non-profit sectors, to come together and develop longer-term action recommendations for orca recovery and future sustainability.

The task force’s main goals were to reduce the harm of the three main challenges facing orcas: pollution; lack of access to their primary prey, the chinook salmon; and boat traffic noise.

And though it’s only been about six months since Gov. Jay Inslee created a task force to draw up some guidelines about how to help the local Southern Resident orca population, it feels like a different world for the whales.

The pods had a rocky summer, starting with the latest census data showing that their population had dipped to a 30-year low, having lost 25 percent of the local orcas since the 1990s. Shortly after that, Tahlequah made headlines around the world when she swam with the body of dead calf for a week, covering 1,000 miles.

Later in the summer, the youngest member of the J-pod fell ill. Despite many researchers attempting to help get her back up to fighting weight, her disappearance and assumed death marked another disheartening chapter to the summer of the Southern Residents.

It’s especially discouraging considering that the outlook is a lot sunnier up north — the Northern Resident orca population has doubled since 1974, to a total of 309.

But the end of the summer brings a few bright spots: Multiple Southern Residents appear to be pregnant, and the task force’s guidelines are finally being filed.

“I look at 2018, and I hope this is the low point,” Barry Thom, regional administrator for NOAA fisheries West Coast Region, said a hearing regarding the orcas in Friday Harbor earlier this year. “The clock is running out on killer whale recovery, and it is heart wrenching to see.”

Draft recommendations released for public comment include significantly increasing investment in restoration and acquisition of habitat in areas where chinook salmon stocks most benefit Southern Resident orcas, immediately funding acquisition and restoration of nearshore habitat to increase the abundance of forage fish for salmon, and determine whether the removal of some dams would provide benefits to the Southern Resident orca population.

NOAA Issues Report on Protecting North Atlantic Right Whales

November 12, 2018 — NOAA Fisheries researchers have been looking into how to preserve the shrinking population of critically endangered North Atlantic Right Whales.

Officials have concluded that the surest way of protecting the species is by preserving the lives of adult females in the population as a way to promote population growth and recovery.

According to Royal Society Open Science, most right whale deaths are attributed to entanglement in fishing gear and collisions with ships.

Declining species’ future tops agenda at whale of a meeting

November 9, 2018 — A group of scientists, conservationists and others is meeting in Massachusetts to brainstorm strategies to save one of the rarest marine mammals on the planet.

It’s the North Atlantic Right Whale Consortium’s annual meeting, and it’s wrapping up on Thursday at the Whaling Museum in New Bedford. The right whales number only about 440 and have suffered from high mortality and poor reproduction in recent years.

The meeting began on Wednesday. The agenda includes sessions about everything from the summertime occurrence of the whales in the Bay of Fundy to changes in the abundance of the tiny organisms they need to eat to survive.

New estimate lowers number of right whales

November 9, 2018 — A gut feeling among North Atlantic right whale experts that the population of the beleaguered animals has dropped to around 400 has been reinforced with a new statistical estimate of 411 animals as of the end of 2017.

“The public shouldn’t think there are exactly 411 whales,” Center for Coastal Studies right whale researcher Charles “Stormy” Mayo said Thursday at the end of the two-day North Atlantic Right Whale Consortium annual meeting in New Bedford. “We believe that they are in the low 400s, or around 400.”

The consortium’s annual report card for the end of 2016 had set the population number at 451, using a statistical model unveiled last year.

The loss of about 40 right whales, under the statistical model, between the end of 2016 and the end of 2017 would include the 12 documented deaths in the Gulf of St. Lawrence in Canada and the five off the Cape and Islands linked in large part to human causes of entanglement in fishing rope and being struck by ships.

“Everyone in the field – conservationists, the public, scientists – continue to be saddened by the decline,” Mayo said. “There’s no question there’s a decline. There’s no question we need to solve the mortality issue.”

The maximum number of human-caused deaths should be no more than one a year to sustain the critically endangered population along the U.S. and Canadian coast, according to a federal stock assessment in September.

U.S. and Canadian government agencies and nonprofit organizations are working to identify the best ways to respond, with new technology to eliminate vertical ropes in the water, for example.

MASSACHUSETTS: Losing lobster lines

November 6, 2018 — Scientists from the New England Aquarium will spend much of next year testing ropeless lobster gear as part of the escalating effort to mitigate entanglements with right whales and other marine species.

The research project, funded with a $226,616 grant recently received from the National Oceanic and Atmospheric Administration, will involve co-operative research with active lobstermen, possibly including some from the state’s most lucrative lobster port in Gloucester, according to one of the aquarium’s chief scientists.

“We want to get good technology in the hands of fishermen so they can evaluate its potential,” said Tim Werner, the aquarium’s senior scientist and director of its Consortium for Wildlife Bycatch Reduction. “They need to be able to use it and find out what it needs to be functional.”

Werner said researchers already have begun to develop various types of ropeless traps, using different technologies to achieve the same goal of drastically reducing or eliminating entanglements of leatherback sea turtles and whales in the forest of vertical lines stretching from fishing gear on the ocean floor to the ocean’s surface.

Wildlife NGOs urge Canadian gov’t to expand right whale protection

November 5, 2018 — Wildlife protection groups, led by the Centre for Biological Diversity (CBD), have submitted recommendations to the Canadian government urging them to uphold and expand the existing protections for the North Atlantic right whale, a press release said.

The measures put in place this year to outlaw forms of entanglement fishing in the Gulf of St. Lawrence followed the news that 12 right whales had died in Canadian waters in 2017. The Canadian Department of Fisheries and Oceans (DFO) responded by closing key fishing areas in the gulf, including the entanglement-prone snow crab fishery.

Aside from the recommendation to expand the protected area, the letter also requested that all Atlantic Canadian fisheries have marked equipment, enabling the owners of entanglement gear to be identified; and make the transition from trap/pot fisheries to ropeless gear.

“The right whale population is plummeting as these incredible animals continue to get entangled in Canadian and US fishing gear,” said Sarah Uhlemann, international program director at the CBD.
