CALIFORNIA: Monterey Bay fishermen work to reduce chances of whale entanglements

July 13, 2021 — On a cool Thursday morning this week, Calder Deyerle powered up his Boston Whaler and headed out of Moss Landing Harbor in search of the catch of the day. But this catch had no fins or tails or claws. Deyerle was hunting crab gear.

Five or six years ago, more than 70 whales — mostly fin, blue and humpbacks — became caught in the lines that connect a surface buoy to the crab trap resting on the ocean floor. Because of a crash in the krill population, the whales came in closer to shore to feed on alternative food sources and right into the crab lines.

Lines and traps meant for Dungeness crabs can be deadly to whales that become ensnared in the equipment, often causing dehydration, infected wounds, breathing or reproduction problems and even starvation.

But efforts by Dungeness crab fishermen have dramatically reduced the number of whale entanglements. There have been none this year. The far greater threat to whales today is not from crab gear, rather from ship strikes.

Deyerle is one of nine Monterey Bay commercial fishermen who are contributing to a project called the Lost Gear Recovery Project that is coordinated by the Monterey Bay Fisheries Trust, which in turn is permitted by the California Department of Fish and Wildlife.

Track Whale Detections With This Interactive Map

June 25, 2021 — The following was released by NOAA Fisheries:

Scientists at the Northeast Fisheries Science Center have created a new data mapping tool to help people understand when and where large whales occur off the East Coast.

The underlying data include detections made by underwater listening devices — called hydrophones — operated from stationary platforms, such as bottom-mounted moorings and surface buoys. They were also made by mobile platforms like Slocum gliders and towed hydrophone arrays. The map includes sounds made by sei, fin, blue, humpback and North Atlantic right whales from 2004 to the present.

“Our goal was to provide all the archived data we have, plus data from collaborators, in one place and make it easy for managers, stakeholders and scientists to access it themselves and explore the data in a format that would be helpful,” said Sofie Van Parijs, one of the creators and lead of the center’s passive acoustics research group. “We hope to add in data collected by the wind industry, and invite other researchers and sources of this type of data to share what they have with us to make this dataset as comprehensive as possible.”

Those interested in contributing to the data can contact the developers at nmfs.pacmdata@noaa.gov.

Recent additions to the dataset include all beaked whales, sperm whales, and dwarf and pygmy sperm whales (Kogia species) detected from 2013 to the present. Current recording locations range from the waters of the western North Atlantic, off Greenland, to the Caribbean Sea.

Data about each detection is incorporated into the mapping tool, including:

  • Location
  • Season
  • Number of deployments of that recording gear
  • Number of recorded days and detections
  • Type of detection: definite, possible, no detection, or data collected but not yet analyzed.

Massachusetts Lobster Diver Survives After ‘a Humpback Whale Tried to Eat Me’

June 14, 2021 — A commercial lobster diver was injured when he said he was swallowed by a humpback whale off the coast of Cape Cod Friday.

Michael Packard was in the whale’s closed mouth for 30-40 seconds, he said in a Facebook post to a Provincetown, Massachusetts, community page.

“I was lobster diving and A humpback whale tried to eat me.I was in his closed mouth for about 30 to 40 seconds before he rose to the surface and spit me out.I am very bruised up but have no broken bones,” Packard wrote, thankful for the help he received from rescuers in Provincetown and seeking to clarify what had happened to him as it generated headlines worldwide.

His sister, Cynthia Packard had told the Cape Cod Times that Packard was taken to Cape Cod Hospital with at least one broken leg after the encounter Friday morning.

Whale rescuers free humpback from fishing gear entanglement

June 11, 20221 — A three-day effort to free a humpback whale from entanglement in fishing gear ended in success this week, marine mammal experts said Thursday.

The whale, identified as a mature female named Valley, was first spotted Monday by a whale watch boat on Stellwagen Bank northeast of Provincetown, according to a statement from the Center for Coastal Studies.

The center’s entanglement response team found that the whale had a heavy line lodged in its mouth, but because sea conditions were poor, it could not be freed.

California closing Dungeness season June 1 as humpback whales migrate

May 25, 2021 — California crabbers must pull their gear by noon June 1, with a decision by state officials to end the season, anticipating movement of humpback whales from their breeding grounds back to coastal waters.

The closure will shorten the season by four weeks in the central management zone and six weeks in the northern management zone. But the state Department of Fish and Wildlife’s Risk Assessment and Mitigation Program – developed after court challenges from environmental groups seeking to prevent gear entanglements – is working, state officials say.

The agency made its preliminary determination a week before the announcement, said Ben Platt, president of the California Coastal Crab Association.

“What’s extremely frustrating is that the Whale Working Group voted 10-2 to keep the state open with a 30 fathom depth restriction. The only whales spotted were outside of this depth,” said Platt. “This was already the management in the northern half of the state for the past two week period.

NMFS Publishes Finale Rule on Humpback Whales Pacific Ocean Habitat

April 26, 2021 — Pacific Ocean humpback whales gained more protection this week as the National Marine Fisheries Service designated more than 115,000 square nautical miles as critical habitat.

The final rule covers three threatened or endangered populations of humpbacks: the Western North Pacific distinct population segment (endangered), the Central America DPS (endangered), and the Mexico DPS (threatened).

White House Finalizes Pacific Ocean Protections for Humpback Whale

April 21, 2021 — The Biden administration finalized a rule that will conserve approximately 118,000 square nautical miles of the Pacific Ocean as protected habitat for the humpback whale.

The National Oceanic and Atmospheric Administration finalized the rule that conserves a large swath of ocean off the coast of North America, spanning from Southern California to the Bering Sea in Alaska.

Conservationists tout the rule as necessary to protect three separate populations of endangered whales from ship strikes, entanglements with fishing nets and oil spills.

“Pacific humpbacks finally got the habitat protections they’ve needed for so long,” said Catherine Kilduff, an attorney with the Center for Biological Diversity. “Now we need to better protect humpbacks from ship strikes and entanglement in fishing gear, their leading causes of death.”

The finalization of the rule comes after a lengthy court battle between conservationists and the U.S. government ended in a 2018 settlement.

Humpback Whale Season in Hawaiʻi is in Full Swing Right Now

December 21, 2020 — November is when the koholā (humpback whales) return to Hawaiʻi to breed, birth and nurse calves. An estimated 8,000 to 12,000 of the protected marine mammals migrate from Alaska to the Islands’ warm, shallow waters through April, when they head back north again.

This year, though, the first North Pacific humpback whale sighting was reported on Oct. 8 off Maui, according to the Pacific Whale Foundation—earlier than normal. Researchers at the Hawaiian Islands Humpback Whale National Marine Sanctuary, a 13,700-square-mile sanctuary created in 1992 to protect whales in their preferred habitat around the Islands, are getting reports of whale sightings from around the state.

They are also hopeful that total numbers of whales that will be counted this season—now through March 2021—will trend upward. In 2016, numbers dropped nearly 50%, likely due to a lack of food. That was the same year the koholā were removed from the endangered species list.

The COVID-19 pandemic may affect the whale count, too, with fewer whale tours running and fewer visitors in the Islands.

“We can say that (in 2019-20), whale abundance and singing activity was the highest in about five years, indicating that whale numbers in Hawaiʻi have been increasing,” said Marc Lammers, research coordinator with the humpback whale sanctuary, in a webinar he presented last month on the sanctuary’s website.

Whales get a break as pandemic creates quieter oceans

December 10, 2020 — When humpback whales migrated to Glacier Bay in Alaska this year to spend the long summer days feeding, they arrived to something unusual: quieter waters.

As the COVID-19 pandemic slows international shipping and keeps cruise ships docked, scientists are finding measurably less noise in the ocean. That could provide momentary relief for whales and other marine mammals that are highly sensitive to noise.

Through networks of underwater hydrophones, scientists are hoping to learn how the mammals’ communication changes when the drone of ships is turned down, potentially informing new policies to protect them.

“More needs to be done,” says Jason Gedamke, who manages the ocean acoustics program at NOAA Fisheries. “When you have animals that for millions of years have been able to communicate over vast distances in the ocean, and then once we introduce noise and have increased sound levels and they can’t communicate over those distances, clearly there’s going to be some impact there.”
