This small, lowly sponge from Alaska may have special powers: curing cancer

July 28, 2017 — An obscure Alaska sea sponge, unknown to science until about a decade ago, shows promise as a tool to help patients fight pancreatic cancer, a notoriously deadly and hard-to-treat disease, researchers say.

The sponge, first spotted in 2005 on the floor of the eastern Gulf of Alaska off Baranof Island, holds unusual molecules that target and kill pancreatic cancer cells in the laboratory.

The Alaska sponge now shows more promise as pancreatic-cancer fighter than any of the other sea sponges or plants, marine creatures and bacteria that Mark Hamann of the Medical University of South Carolina and Fred Valeriote of the Henry Ford Cancer Institute in Detroit have examined over the past two decades.

“This is certainly, for us, the best and most exciting looking candidate for the control of pancreatic cancer that we’ve come across in that 20-year period,” Hamann said in a teleconference with reporters Wednesday hosted by the National Oceanic and Atmospheric Association, which is collaborating in the research.

Pancreatic cancer is one of the most difficult cancers to control and spreads rapidly to nearby parts of the body, according to the Mayo Clinic in Rochester, Minnesota. The pancreas is a part of the digestive system, secreting hormones that enable the body to process sugars.

The Alaska sponge was discovered by Bob Stone, a NOAA Fisheries biologist conducting an ocean-floor survey of coral habitat that fishery managers were interested in protecting.

It immediately stood out for its green color, contrasting with the browns common to Southeast Alaska sea sponges, said Stone, who was in the submersible vessel doing the survey. It looked like a sponge from the faraway Aleutians, he said.

“The second I saw it, I thought I should collect it,” he said.

North Pacific Fisheries Management Council names new executive director

June 28, 2017 — The North Pacific Fisheries Management Council announced it has a new executive director last week. Former Deputy Director David Witherell will be taking over for Chris Oliver, who was appointed to manage fisheries for the National Oceanic and Atmospheric Administration.

The council manages halibut and ground fish in the Gulf of Alaska, along the Aleutian Islands and the Bering Sea. Witherell said he’s prepared to take over the position.

“Fortunately my predecessor Chris Oliver spent quite a bit of time training me to take over the reins, and he gave me a deep understanding of the type of work and gave me the experience to understand what I was getting into as executive director someday,” Witherell explained.

Is the Cook Inlet beluga population stable or in danger? Depends on whom you ask.

June 29, 2017 — Alaska’s most urban whales have yet to show any meaningful increase in numbers, evidence that recovery remains elusive for the endangered population despite numerous protective measures imposed in recent years. On the plus side, the Cook Inlet beluga population has not declined notably in the past two years, scientists say.

The latest survey of the small and endangered white whales estimates the population at 328 animals, within a range of 279 and 386, the National Oceanic and Atmospheric Administration reports.

That represents barely any change from the previous estimate of 340 animals, from 2014, but far below the 1,300 belugas that scientists say were swimming three decades ago in the silty, salty water between Anchorage and the Gulf of Alaska.

“Cook Inlet belugas are still in danger of extinction because the population is so small,” said Paul Wade, head of Cook Inlet beluga research at NOAA’s National Marine Fisheries Service. “The population trend over the last 10 years has been relatively stable compared to the steep decline seen in the 1990s, but there is some evidence the population has continued to decline slightly. We are concerned that the population is not yet increasing towards its former abundance level,” Wade said in a prepared statement.

The newest population estimate comes from the latest in a series of regular aerial counts conducted by NMFS. The estimate is based on thousands of photographs taken from the air a year ago; analysis of those images is a laborious process, so the count that emerged required a full year of work and review, officials said.

Jellied sea creatures confound scientists, fishermen on U.S. Pacific Coast

June 28, 2017 — Drifting throngs of jelly-like, glowing organisms native to tropical seas far from shore have invaded Pacific coastal waters from Southern California to the Gulf of Alaska this year, baffling researchers and frustrating fishing crews.

Known as pyrosomes, they are tubular colonies of hundreds or thousands of tiny individual creatures called zooids, enmeshed together in a gelatinous tunic roughly the consistency of gummy bear candy.

No relation to jellyfish, they resemble bumpy, opaque pickles in the water, typically a few centimeters or inches long, though some grow 1 or 2 feet (30cm or 60cm) in length.

They feed by filtering microscopic algae, or phytoplankton, as they float with the current, and are known to glow in the dark – a bioluminescent characteristic that gives the organism its scientific name — Pyrosoma, Greek for “fire body.”

Pyrosomes have rarely if ever been seen along the U.S. West Coast until 2012, when first spotted in California waters. Since then, they have gradually multiplied and spread north, before exploding in numbers this spring, according to scientists with the National Oceanic and Atmospheric Administration (NOAA).

Although harmless to humans, they have been especially troublesome to the commercial salmon catch in Oregon, with large globs of the rubbery critters clogging fishing gear by the thousands in recent months. Some have even washed ashore.

“It gets to a point where they’re so abundant, you can’t even fish out there, so you have to pick up your gear and move elsewhere,” Nancy Fitzpatrick, executive director of the Oregon Salmon Commission, said on Monday.

A single five-minute trawl with a research net by scientists off the Columbia River in late May scooped up roughly 60,000 pyrosomes, NOAA reported.

Fishermen were also hit in southeastern Alaska, where some crews suspended operations earlier this year when pyrosome densities were at their height, said Aaron Baldwin, a fishery biologist for the Alaska Department of Fish and Game.

Electronic monitoring finally catching on among Alaska’s commercial fishermen

April 10, 2017 — Automation is coming to Alaska fishing boats in the form of cameras and sensors that track what’s coming and going over the rails.

Starting next year, electronic monitoring systems can officially replace human observers as fishery data collectors on Alaska boats using longline and pot gear. Vessel operators who do not voluntarily switch to electronic monitoring remain subject to human observer coverage on randomly selected fishing trips.

The onboard observer requirement originally covered vessels 59 feet and longer, but was restructured in 2013 to include boats down to 40 feet and, for the first time, was applied to the halibut fishery.

“Those smaller vessels have had a hard time accommodating human observers,” said Bill Tweit, vice chairman of the North Pacific Fishery Management Council, which oversees the program.

Smaller boats also had a hard time with skyrocketing observer costs under the restructured program, which in some cases went from less than $300-$400 per day to more than $1,000.

Starting in 2013, 15 pot cod boats aligned with the Homer-based North Pacific Fisherman’s Association and Saltwater Inc. of Anchorage field tested electronic monitoring in the Gulf of Alaska.

NSF announces new long-term ecological research sites off Alaska, New England coasts

March 9, 2017 — National Science Foundation (NSF) grants will support two new Long-Term Ecological Research (LTER) sites. Scientists will conduct research along the Northeast U.S. continental shelf and in the northern Gulf of Alaska, regions known for productive fisheries and abundant marine resources.

The new LTER sites were each awarded $5.6 million over five years, adding to 25 existing LTER sites in ecosystems including the open ocean, coral reefs, deserts and grasslands. The complex food webs in these regions are affected by human activities, short-term environmental variability and long-term ecosystem changes.

“The new LTER sites will bring new locations, technologies and scientists to the challenge of understanding our coastal oceans,” says Rick Murray, director of NSF’s Division of Ocean Sciences. “The sites are in areas where there’s much recreational and commercial fishing, and both sites are in the midst of significant environmental changes.”

Disaster Declared for West Coast Fisheries

January 23, 2017 — SEATTLE — Nine West Coast salmon and crab fisheries have been declared a disaster, allowing fishing communities to seek relief from the federal government.

Secretary of Commerce Penny Pritzker declared the disaster on Jan. 18.

Nine salmon and crab fisheries in Alaska, California and Washington suffered “sudden and unexpected large decreases in fish stock biomass or loss of access due to unusual ocean and climate conditions,” the National Oceanic and Atmospheric Administration said.

The fisheries include Gulf of Alaska pink salmon, California Dungeness and rock crab, and several tribal salmon fisheries in Washington.

Northeast Pacific is the region producing most Marine Stewardship Council fish

December 23, 2016 — The Northeast Pacific fishing area annually produces a total of 2.6 million metric tons of certified seafood from Marine Stewardship Council (MSC) sustainable fishing standard, representing 83 per cent of the total catch of the area.

The MSC certified seafood from the area — covering Northern California, Oregon, Washington, British Columbia, Gulf of Alaska and Bering Sea waters — ranks first for the percentage and includes MSC certified salmon, albacore tuna, pink shrimp, hake, halibut, sablefish, Pacific cod, and Alaska pollock fisheries.

Another North American fishing area, the Northwest Atlantic — waters from North Carolina, the US mid-Atlantic, New England, and Eastern Canada — ranked seventh globally with 32 per cent (580,000 metric tons) of the total catch being MSC certified.

This area is home to MSC certified swordfish, spiny dogfish, sea scallop, lobster, Acadian redfish, haddock, pollock, Atlantic halibut, snow crab, Northern shrimp and Arctic surf clam fisheries.

The analysis and ranking was done as part of the recently published MSC Annual Report 2015-2016, which also reported that MSC certified fisheries caught more than 9.3 million metric tons of seafood in 2015-16, representing almost 10 per cent of the total global wild caught seafood by volume.

The global volume of MSC certified catch has increased by 6 per cent since 2014-15, while the MSC certified supply chain has climbed 16 per cent over the same period.

Between April 2015 and March 2016, the number of processors, restaurants and caterers with MSC Chain of Custody grew from 2,879 to 3,334 companies, operating in 37,121 sites across 82 countries. More than 20,000 products now carry the blue MSC label and can be traced back to fisheries which meet the MSC’s world-class standard for sustainable fishing.

Commenting on the results, Brian Perkins, MSC Regional Director – Americas, said, “When people purchase MSC certified seafood, their choice supports fishermen around the world who are working hard to meet the world’s most rigorous standard for environmental sustainability.”

“While we’re proud of the MSC certified fisheries here in North America, it takes a global effort to safeguard seafood supplies for the future,” pointed out Perkins.

For her part, Christina Burridge, Executive Director, B.C. Seafood Alliance and Chair, International Association of Sustainable Fisheries, stressed that fishermen on the Pacific Coast of the US and Canada are proud to be recognized by the MSC for their responsible stewardship of a renewable food resource for their countries and the world.

Bering Sea groundfish looks strong as warming Gulf sees cuts

December 12, 2016 — Bering Sea fish stocks are booming but it’s a mixed bag for groundfish in the Gulf of Alaska.

Fishery managers will set 2017 catches this week (Dec.7-12) for pollock, cod and other fisheries that comprise Alaska’s largest fish hauls that are taken from three to 200 miles from shore.

More than 80 percent of Alaska’s seafood poundage come from those federally-managed waters, and by all accounts the Bering Sea fish stocks are in great shape.

“For the Bering Sea, just about every catch is up,” said Diana Stram, Bering Sea groundfish plan coordinator for the North Pacific Fishery Management Council.

There are 22 different species under the Council’s purview, along with non-targeted species like sharks, octopus and squid. For the nation’s largest food fishery — Bering Sea pollock — the stock is so robust, catches could safely double to nearly three million metric tons, or more than six billion pounds!

But the catch will remain nearer to this year’s harvest of half that, Stram said, due to a strict cap applied to all fish removals across the board.

“That means the sum of all the catches in the Bering Sea cannot exceed two million metric tons,” she explained.

While Bering Sea groundfish booms, Gulf of Alaska struggles

December 5th, 2016 — Bering Sea fish stocks are booming, but it’s a mixed bag for groundfish in the Gulf of Alaska.

Fishery managers will set 2017 catches this week for pollock, cod and other fisheries that make up Alaska’s largest fish hauls, which are taken from 3 to 200 miles offshore. More than 80 percent of Alaska’s seafood comes from those federally managed waters, and by all accounts the Bering fish stocks are in great shape.

“For the Bering Sea, just about every catch is up,” said Diana Stram, Bering groundfish plan coordinator for the North Pacific Fishery Management Council.

Twenty-two species are under the council’s purview, along with such nontargeted species as sharks, octopus and squid. For the nation’s largest food fishery — Bering pollock — the stock is so robust that catches could safely double to nearly 6 billion pounds, according to National Oceanic and Atmospheric Administration scientists who presented their data to the council last week.

But the allowable catch will remain close to this year’s harvest, Stram said, due to a strict cap applied to all fish removals.

“The sum of all the catches in the Bering Sea cannot exceed 2 million metric tons,” she explained.

With all stocks so healthy, catch-setting becomes a trade-off among the varying species, Stram said. The council also sets bycatch levels for the fisheries, another constraint.
