Alaska: In Nome, state experts ponder responses to Bering Sea crises

February 21, 2018 — Experts from around the state gathered in Nome to discuss marine mammals and how multiple entities can respond to different types of emergencies that may happen in the Bering Sea.

Mandy Migura with the National Marine Fisheries Service was one of the presenters at a “Strait Science” talk hosted at University of Alaska Fairbanks Northwest Campus.

Migura discussed how marine mammal stranding events take place in Alaska sporadically but have been rising in numbers since tracking began in the 1980s.

“Strandings involve live marine mammals. these may be animals that are unable to return to their natural habitat without some kind of assistance. And they may be injured, they may be entangled in gear or marine debris, they may be entrapped — ice entrapment, ice may form up and they’re in an area where they can’t get back to where they should be — or they may be disoriented, may be a health issue or something in the environment that’s affecting them.”

Migura is Alaska’s marine mammal stranding coordinator and said dead marine mammals can also be categorized as stranded.

With more cases of marine mammal strandings being reported, the Bering Sea marine ecosystem is currently in a volatile state.

Nome-based marine advisory agent Gay Sheffield mentioned how sharks have been found more frequently in the Bering Straits region, with the latest one documented in Gambell in summer 2017.

On the other side of St. Lawrence Island, a stellar sea lion was harvested last year in Savoonga, which she said is uncommon.

Migura said local and regional partners reporting this kind of information greatly benefits the National Marine Fisheries Service.

A new study looks at why Pacific Cod stocks are crashing in the Gulf of Alaska

February 14, 2018 — A new study in Kodiak will hopefully shed some light on what Pacific cod go through when they’re young.

“We don’t know how they do in the winter. Where they are. What they are eating. What their energetic requirements are.”

One of the leaders of the project, Mike Litzow is a researcher for the University of Alaska Fairbanks based in Kodiak.

He said the recent crash in the Pacific cod population in the Gulf of Alaska was a wake-up call that there’s a lot to be learned about the early life stages of Pacific cod.

A few years ago a body of warm water settled in the gulf and it may have made it difficult for juvenile cod to survive.

“The operating hypothesis right now is that you can warm the temperatures up and they’ll survive if there’s enough food, but there wasn’t enough food to meet those requirements.”

The National Marine Fisheries Service, according to Litzow, recently found that the Pacific cod population had dropped by about 60 percent since 2015.

The North Pacific Fisheries Pacific Council reduced the amount of Pacific cod that can be caught by commercial fishermen in the Gulf of Alaska by about 80 percent because of the crash.

The decrease in cod will be hard for Kodiak fisherman because Pacific Cod is one of the bigger fisheries in the region.

Litzow thinks Kodiak will have to face the possibility that more fishery disasters could be in its future because of climate change.

Why are Pacific Cod Stocks Crashing?

February 13, 2018 — “The status of Pacific cod is probably the biggest fishery issue facing Kodiak right now, with the quota cut 80 percent for 2018,” said Mike Litzow, a University of Alaska Fairbanks associate professor at the Kodiak Seafood and Marine Science Center.

Pacific cod stocks have collapsed, possibly because recruitment (production of young fish to enter the population) has been very low during a recent string of incredibly warm years in the Gulf of Alaska, he said.

Scientists don’t know why cod stocks are shrinking. The leading hypothesis is that warmer temperatures increase the metabolic rates of young cod, and their food sources don’t supply enough energy.

There’s a sticking point—there’s not enough data to test the theory. Studies of fish ecology and population dynamics in Alaska are overwhelmingly conducted in the summer. Almost nothing is known about wintertime ecology of juvenile Pacific cod.

To help provide answers, Litzow and fisheries oceanographer Alisa Abookire embarked on a pilot study this month to collect information about habitat use, diet and energetics of juvenile cod.

They are sampling the fish with a beach seine and taking ocean water data aboard a semi-enclosed 22 foot skiff. To stay warm they wear insulated paddling suits.

Litzow and Abookire are collaborating with scientists at the Hatfield Marine Science Center in Newport, Ore., who have been studying juvenile cod in Kodiak over the last 12 years. The pilot study is funded by the Ocean Phoenix Fund through the University of Alaska Foundation.

Cantwell, Huffman, Colleagues to Trump Admin: “Listen to Our Fishermen” and Save Bristol Bay from the Pebble Mine

White House plan to reverse clean water rules paves the way for construction of Pebble Mine, a catastrophic move for Bristol Bay watershed, 60 million salmon, and more than 20,000 jobs

Decision flies in the face of science and basic reason, made with no public input from fishermen or business groups

October 11, 2017 — WASHINGTON — The following was released by the office of Senator Maria Cantwell:

Today, U.S. Senator Maria Cantwell (D-WA), Rep. Jared Huffman (CA-02), and 40 of their colleagues in the House and Senate sent a forceful letter to President Trump urging caution and a careful consideration of the facts before his administration removes the science-based environmental rules that protect Alaska’s Bristol Bay and the fishermen who depend on it.

Removing the existing clean water protections allows for the construction of Pebble Mine, an open-pit copper and gold mine that could have a depth equivalent to as much as two and a half Trump Towers. The mine would be an unmitigated catastrophe for the Bristol Bay watershed and the 40-60 million salmon who return to it every year. A three-year Environmental Protection Agency (EPA) study in 2014 found that the proposed mine would, even in the course of normal, safe mine operations, destroy 24 to 94 miles of salmon-producing waterways and pristine environment.

The University of Alaska Institute of Social and Economic Research found that the Bristol Bay fishery supports more than 20,000 jobs and adds $674 million of economic activity to the states of Washington, Oregon, and California. The region also supports a prolific outdoor recreation industry; anglers from around the world take roughly 37,000 fishing trips annually to Bristol Bay, generating $60 million in economic activity.

“The EPA’s plan to reverse clean water safeguards is egregious and inconsistent with science, and frankly, inconsistent with basic logic,” wrote the members of Congress. “The Pebble Mine directly threatens our maritime economy and thousands of American jobs that rely on this world class fishery. We ask you to listen to America’s fishermen and businesses and reverse EPA’s decision to undo strong protections and clean water safeguards in Bristol Bay.”

Cantwell, Huffman, and their colleagues note the process that established the current clean water safeguards were the result of rigorous scientific analysis and peer review, over one million public comments, and eight public hearings.

In stark contrast, the Trump Administration’s recent decision to roll back the protections has no scientific basis and has been carefully removed from the public eye. There has been no input from stakeholders such as the fishing, tourism, and outdoor industries. Only two public hearings have been noticed, neither of which are scheduled for Washington, Oregon or California where many Bristol Bay commercial and sports fishermen reside.

In their letter, the members of Congress also called for public hearings, a 90-day extension of the public comment period, and other transparency measures to ensure the public is allowed to make their voices heard. Restrictions on mining have the support of 90% of local Bristol Bay residents.

Senator Cantwell successfully led the fight to save Bristol Bay when Pebble Mine was first proposed. In 2011, she urged the EPA to use authority under the Clean Water Act to block large scale development in Bristol Bay. She continued the drumbeat through 2014, when she rallied supporters at Fisherman’s Terminal in Seattle to urge President Obama and the EPA to continue to prevent mining in the area.

In addition to Sen. Cantwell and Rep. Huffman, 40 additional member of Congress signed the letter including: Senators Dianne Feinstein (D-CA), Ron Wyden (D-OR), Patty Murray (D-WA), Jeff Merkley (D-OR), Kamala Harris (D-CA), Sheldon Whitehouse (D-RI), Edward Markey (D-MA) and Representatives Suzanne Bonamici (OR-01), Earl Blumenauer (OR-03), Barbara Lee (CA-13), Grace Napolitano (CA-32), Jackie Speier (CA-14), Anna Eshoo (CA-18), William Keating (MA-09), Adam Smith (WA-09), Denny Heck (WA-10), Eleanor Holmes Norton (DC-Del.), Pramila Jayapal (WA-07), Alan Lowenthal (CA-47), Dwight Evans (PA-02), Peter DeFazio (OR-04), Zoe Lofgren (CA-19), Jamie Raskin (MD-08), Emanual Cleaver, II (MO-05), Rick Larsen (WA-02), Derek Kilmer (WA-06), Mark DeSaulnier (CA-11), Judy Chu (CA-27), Ro Khanna (CA-17), Jerry McNerney (CA-9), John Garamendi (CA-3), Suzan DelBene (WA-01), Kurt Schrader (OR-05), Jimmy Panetta (CA-20), Donald S. Beyer, Jr. (VA-08), Norma Torres (CA-35), Doris Matsui (CA-06), Ted Lieu (CA-33), Linda Sánchez (CA-38), Julia Brownley (CA-26), and Salud Carbajal (CA-24).

NOAA recommends millions in grants to study salmon, cod, shrimp, lobster

June 14, 2016 — The National Oceanic and Atmospheric Administration (NOAA) announced its support for more than USD 11 million (EUR 9.8 million) in recommended grants to study or improve the nation’s fisheries as part of its Saltonstall-Kennedy grant competition.

The grants, which still must be approved by the NOAA Grants Management Division and the Department of Commerce’s Financial Assistance Law Division, and are contingent upon adequate funding availability, include projects in seven categories: aquaculture, fishery data collection, bycatch reduction, climate change adaptation, marketing, socio-economic research and territorial science.

All areas of the United States, including overseas territories, have projects that have been recommended.

In Alaska, they include a proposed University of Alaska, Fairbanks study of halibut bycatch management (USD 297,995, EUR 264,877) and an Alaska Department of Fish and Game analysis of pink salmon productivity (USD 249,998, EUR 222,222).

Pacific cod eating seabirds, study shows

November 9, 2015 — You could call it revenge on the birds.

While many marine birds are well known for their skills at diving into the sea to pluck out fishy meals, there is now solid evidence that some Pacific cod have turned the tables on the avian species.

The practice came to light a few years ago when seafood workers in Dutch Harbor noticed that some of the cod they were processing came with extra features — partially digested birds in the fish stomachs.

Scientists from the Alaska SeaLife Center and University of Alaska have now examined remains of 74 birds collected from cod stomachs in 2011 and have some findings described in a study published online in the journal Marine Ornithology.

The bird remains come from cod caught in the Aleutian Islands region, off Cape Sarichef in Unimak Pass, using trawl and pot gear. The fish were processed at the UniSea plant in Dutch Harbor; the plant froze the bird remains and sent them to the scientists for analysis.

There have been other known cases of big fish eating small seabirds elsewhere in the world, the new study says, and past surveys by the National Oceanic and Atmospheric Administration have turned up, in very rare instances, bits of birds inside cod. In one case, a NOAA researcher found a murre foot in a cod stomach.

But the evidence from Dutch Harbor appears to be the first documentation of Pacific cod making a practice of eating birds, said study co-author Tuula Hollmen, science director at the SeaLife Center and an associate professor at the University of Alaska Fairbanks’ School of Fisheries and Ocean Sciences.
