To get good credit, Alaska’s fishing towns may have to factor in climate change

February 15, 2018 — Late last year one of the world’s largest credit rating agencies announced that climate change would have an economic impact on the U.S.

Moody’s suggested that climate risks could become credit risks for some U.S. states.

Even though Alaska is warming nearly twice as fast as the rest of the U.S., its credit rating doesn’t seem to be in danger. But take a closer look at some of the state’s coastal communities and the story changes, especially when Alaska’s fishing towns consider adding climate risks to their balance sheets.

Frank Kelty is the mayor of the Unalaska, a tiny town is on an island sandwiched between the Bering Sea and the Gulf of Alaska, near some of the richest fishing grounds in the world.

Kelty has been there for 45 years, and lately, he’s seen a lot of changes.

“We’ve had a huge increase in humpback whales coming right into the inner harbor by the road system. Just hundreds of them hanging around,” he said.

People have been pulling off of the road to watch what he calls the “whale show.”

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.

Murkowski, Sullivan Applaud Emergency Relief for Communities Affected by Fisheries Disasters

February 12, 2018 — WASHINGTON — U.S. Senators Lisa Murkowski (R-AK) and Dan Sullivan (R-AK) Friday applauded the inclusion of funding for fisheries disasters in the Bipartisan Budget Act, which established funding levels through the end of Fiscal Year 2019. The bill passed the Senate in a vote of 71-28.

Last month Senators Murkowski and Sullivan called on their colleagues to include disaster funding for coastal communities affected by longstanding and ongoing fisheries disasters, as Congress considered a relief package for U.S. communities impacted by hurricanes and wildfires.

“The dollars contained in this bill are truly vital to communities in the Gulf of Alaska who were hit hard by the pink salmon fishery in 2016. From commercial fisherman and processors to local governments who saw less revenue, this hit everyone hard,” said Senator Murkowski. “I’d like to thank my colleagues on the Senate Appropriations Committee, especially Senators Cochran and Shelby, for working with me over the months to secure this aid for Alaska and other states impacted by these disasters.”

“The 2016 pink salmon season was a disaster for our coastal communities, fishing families, and other fisheries related businesses,” said Senator Sullivan. “This emergency aid was a long time coming, and I thank my Senate colleagues for working with Senator Murkowski and I to address this pressing issue. Going forward we’ll work with NOAA and the affected communities to make sure the dollars are put to good use.”

With New Camera Technology, Scientists Will Survey Untrawlable Ocean Habitat in AK Next Year

February 8, 2018 — SEAFOOD NEWS — NOAA is releasing more information about its thinking about camera monitoring.

In a recent newsletter, NOAA said cameras can go where humans cannot and new fisheries research tools can save hundreds of hours in analyzing information contained in collected photographs.

NOAA Fisheries scientists are designing the first large-scale image-based fish survey in Alaska, and one of the first untrawlable habitat surveys nationwide.

Bottom-trawl and midwater acoustic surveys have been the main source of fishery-independent data for assessing fish stocks in Alaska. But a bottom trawl cannot sample the steep, rocky areas– untrawlable habitats — that species such as Atka mackerel and rockfishes prefer.  Acoustic instruments can be used in these areas, but are limited in detecting fish on or near the seafloor and cannot discern between fish species or sizes. Untrawlable areas make up to 17% of federally managed areas where bottom trawl surveys are regularly conducted in the Gulf of Alaska, and 54% in the Aleutian Islands.

Historically, untrawlable areas were inaccessible not only to scientific surveys, but also to commercial fishing bottom trawls. That is no longer the case.

“Fishermen have made great technological advances,” explains Kresimir Williams, a fisheries biologist at the Alaska Fisheries Science Center who together with colleague Chris Rooper is leading the effort to design a survey of untrawlable habitat in Alaska.

“They are using the latest and greatest gadgets to fish as efficiently as possible. They are using cameras with live view that let them avoid catching boulders in ‘untrawlable’ areas. These areas are not untrawlable anymore – but they are unsurveyed.”

While fishermen use the latest technology, scientific surveys strive to maintain gear consistency to allow direct comparison of survey results over time, so that results from a bottom trawl survey conducted in the 1980s are directly comparable with results from the 2000s. “That consistency gives us confidence that population trends are informative, and can be used to detect changes in fish populations over time allowing the effective management of fish populations. But it hasn’t allowed for the adaptations needed to survey untrawlable areas,” Williams explains.

A number of commercially important fish species– including dusky, northern, harlequin, and yelloweye rockfish– strongly prefer these habitats. Many species of rockfish are long-lived and reproduce later in life, making them particularly vulnerable to overfishing. To keep these fisheries sustainable, managers need accurate stock assessments.

Assessments based on surveys of only trawlable areas for species that live mainly in untrawlable habitat are highly uncertain.  In addition, surveying only trawlable areas may also incorrectly inflate estimates of species such as flatfish, which are predominantly in the trawlable habitats by expanding these results over untrawlable areas where these fish are generally much less common.

Creating rigorous methods for surveying untrawlable habitats will benefit the assessments of both types of fish and the fishing industry and managers who rely on this information to set sustainable fishing quotas.

Take nothing but pictures

The problem of assessing fish stocks in untrawlable habitat is not limited to Alaska. Developing new methods to sample in rock, reef, and other untrawlable habitats is a nationwide NOAA Fisheries effort. Many methods are being explored, but all involve acoustic or optical technologies. Alaska will be one of the first regions to realize an image-based survey of untrawlable habitats if we are able to conduct an initial survey in 2019.

Cameras can go where traditional bottom trawl and acoustic surveys cannot.

The plan for the Gulf of Alaska combines large-scale acoustic and optical sampling. Bottom trawl samples will be replaced with high resolution photos from which fish species and sizes can be identified and fish populations can be estimated. Cameras lowered from ships and moored stationary stereo camera systems will be used where each will be most effective.

“It will be a non-extractive survey,” says Williams. “We will take away nothing but pictures.”

To realize this vision by turning images into data, Williams’ team is collaborating with a University of Washington’s Electrical Engineering department program dedicated to computer automated image analysis. UW researchers and Williams created computer programs that automatically identify and determine the length of fish in the images.

“These sophisticated analysis techniques are widely used in security and medical fields, but are only now becoming accessible for fisheries research,” explains Williams. ”It can hugely reduce the effort required to extract data from images. Until this technique was available, starting a new image-based survey was impractical — it would require a huge number of people and amount of time just to examine photos.”

The new programs are able to analyze the images and determine fish identity and length in one-fifth of the time it would take a trained fisheries biologist to do the task in expenses.

Focus and fine tune

The new survey design is based on many years of research by the Alaska Fisheries Science Center and knowledge gained through NOAA’s Untrawlable Habitat Strategic Initiative, which funded several pilot projects for developing the methodology:

Acoustic-optics studies
Experiments with stationary triggered cameras
Bottom mapping and habitat classification efforts
Remotely operated vehicle surveys
Studies of fish response to camera equipment and movement
A study of fish visual spectrum sensitivity
These studies provided information that is being incorporated into the survey design, such as:

Some fish move to different depths during day and night. This knowledge is useful in deciding what equipment to use or what time of day to survey them.

Some fish move around and others stay close to one location. Understanding these behaviors helps determine what camera equipment to use.

Fish are more sensitive to certain wavelengths of light. The survey will use lighting within a spectrum that fish are least likely to avoid.

Until now, many estimates of fish populations made using traditional survey approaches have been relative — you know if there are more or less than other years, but you don’t know exactly how many there are. That approach often requires several years of data to detect a trend, and consistent methods from year to year, even if those methods become outdated. Williams found an innovative way to use new stereo camera systems to calculate the volume of water represented in each image. That enables researchers to calculate the number of fish per volume of seawater (fish per cubic meter), an absolute estimate.

“With the new survey, we are shooting for an absolute estimate– the actual number of fish. That gives you a much more precise piece of information to work with. And you can keep improving the gear instead of being constrained to using the same techniques for consistency. It’s exciting, using these advanced technologies to do something completely new,” says Williams. “It’s the next place to go.”

Network seeks to bring together data on harmful algal blooms

February 6, 2018 — A group of scientists is coming together to share information related to harmful algal blooms in Alaska.

Under the umbrella of the Alaska Ocean Observation System, part of the national ocean observation system network, a partnership of state agencies, Alaska Native organizations and the University of Alaska has launched the Alaska Harmful Algal Bloom Network. The intent is to stitch together a statewide approach to researching, monitoring, responding to and spreading information about harmful algal blooms in the state.

Algal blooms are natural processes in the ocean and occur when the population of algae in a certain area increases dramatically. However, they can turn toxic when certain types of algae proliferate and produce chemicals that can be harmful to other plants, animals and people, or consume all the oxygen in the water as they decay. The events, called harmful algal blooms, occur all over the planet, in both freshwater and the ocean, according to the National Oceanic and Atmospheric Administration.

“Over the last 10 years, we’ve been seeing more and more of these bloom events happening,” said Ginny Eckert, a professor at the University of Alaska Fairbanks in Juneau and co-chair of the Alaska Harmful Algal Bloom Network’s executive committee. “It’s always a question: Are we seeing more because we’re paying attention more? But … the more information we can get out to people, (the better).”

Harmful algal blooms can have devastating consequences. In 2014, nearly 500,000 Ohio residents had to go without clean drinking water because of harmful algal blooms near a water treatment plant in Lake Erie. A harmful algal bloom in a lake that flowed into the ocean near Monterey Bay, California in 2007 is thought to have killed 11 sea otters with infections of microcystin, according to the Centers for Disease Control and Prevention. Every year in Alaska, a number of alerts go out to shellfish gatherers to be careful because some of the clams, oysters and mussels may have high levels of a toxin that causes paralytic shellfish poisoning, a fatal condition in humans.

Bering Sea cod season has potential to be shortest ever

January 19, 2018 — The trawling season for Pacific cod in the Bering Sea begins 20 January, although the season will likely draw to a close earlier than mid- to late-March, when the season traditionally ends.

Analysts expect the season to close for a number of reasons. Quotas have decreased in the Bering Sea by about 15 percent to about 414 million pounds of fish. However, it’s the quota decrease in the Gulf of Alaska that is expected to cause more competition and quotas being filled quickly in the Bering Sea.

Due to a severe 80 percent cut in the cod quota in the Gulf of Alaska, the fleets that usually consider those waters their home turf will likely make their way to the Bering Sea to fish for the season, however long it lasts.

The reason for the quota cuts is a severe depletion in Alaska cod stocks which, in recent years, have posted the worst numbers for decades, according to the National Marine Fisheries Service.

Krista Milani, who is a marine biologist at the NMFS, predicted the numbers to rebound in the coming years, since she expects water temperatures to revert to cooler temperatures.

Susan Murray: Crude plan puts Alaska’s fisheries at risk

January 15, 2018 — Last week, the Trump administration unveiled an extreme proposal to open nearly all United States federal waters off Alaska to offshore oil and gas leasing. Under the Draft Proposed Program for the 2019-2024 Outer Continental Shelf Oil and Gas Leasing Program, only the North Aleutian Basin (which contains Bristol Bay) would be safe from potential oil and gas leasing activity. Areas such as the Gulf of Alaska that have not seen a lease sale since the early 1980s, and regions that have never been considered for exploration like the Aleutians, Bering Sea and Kodiak have suddenly been put at risk.

The Gulf of Alaska faced oil and gas lease sales when the first federal offshore leases were offered in Alaska as part of the 1976-1981 program. At that time, 600,000 acres of the seafloor, starting 10 miles off Cape Suckling and stretching to Yakutat, were leased and twelve exploratory wells were drilled. None yielded commercially significant quantities of oil or gas, and thankfully there were no catastrophes from this misguided effort. Further sales were scheduled between 1997 and 2002, but were canceled due to a lack of interest from industry. It was a bad idea then, and it is a bad idea now.

The Bureau of Ocean Energy Management (BOEM) now estimates the recoverable oil and gas reserves in the Gulf of Alaska at around 600 million barrels of oil. Current U.S. consumption is about 20 million barrels per day. In other words, burning through the estimated Gulf of Alaska oil reserves might fuel our country for a mere month. BOEM’s low estimate of environmental and social costs of exploration activities and “small” spills (up to 4 million gallons!) is a staggering $100 million. That doesn’t even include the costs of a catastrophic oil spill, like BP’s Deepwater Horizon disaster, which they claim they will analyze later.

The Gulf of Alaska ecosystem is already stressed, and many fishermen will tell you that things do not look good. Halibut are smaller, Chinook salmon are disappearing, and the Pacific cod stock is collapsing. To add the stress of offshore oil and gas exploration and drilling to the mix is both thoughtless and irresponsible.

Seafood industry seeks new value in fish parts

January 15, 2018 — State seafood marketers are rebranding fish parts as “specialty” products and mapping a path for millions more dollars in sales.

Alaska’s fisheries produce more than 5 billion pounds of seafood each year. When all the fish is headed and gutted or filleted and all the crab legs are clustered, it leaves about 3 billion pounds of trimmings. Some is turned into meal and oil, but for the most part, the “gurry” is ground up and discharged into local waterways.

“Whether that’s heads or guts, milt, or meal or oil or something else, it should be held in high regard,” said Andy Wink, a seafood economist formerly with the McDowell Group. “These are products that are out of our normal range but they are specialty items serving niche markets.”

A new Analyses of Specialty Alaska Seafood Products report compiled for the Alaska Seafood Marketing Institute takes a look at uses for fish heads, oil, meal, internal organs, crab products, roe, herring fillets, arrowtooth flounder, spiny dogfish and skates.

It makes the point that Alaska’s combined seafood catches, valued at roughly $2 billion at the docks and twice that when processors sell to their buyers, could be worth an additional $700 million or more if so called “specialty” products were added to the mix.

Take fish heads, for example. Alaska produces about 1 billion pounds of fish heads per year, which likely account for most of the processing waste, the report said. Just 1 percent is sold as frozen heads, although a single large salmon head can fetch up to $5 a pound at Beijing supermarkets, according to previous reports. Increasing the frozen market alone could add $100 million to processors’ sales, the report said.

North Pacific Council Issues Alert to Gulf of Alaska Cod Fishermen

January 4, 2018 — SEAFOOD NEWS — In big red letters, a one-page alert warns the Gulf of Alaska cod fleets:  “Attention Cod Fishermen! 80% Decrease in Catch Limit for 2018” before describing what the massive cut in landings will mean to all gear types in federal and state waters of the Gulf.

At its December 2017 meeting, the North Pacific Fishery Management Council approved a Gulf-wide catch limit for Pacific cod at 18,000 mt, or about 39.7 million pounds for the 2018 season that starts January 20. Last year’s quota for P-cod in the Gulf for both the federal and state waters was about 82,000 mt.

“Recognizing that cod fishermen in the Central and Western Gulf of Alaska need to quickly get this information to adjust their fishing plans for 2018, the Council is providing the following tables that compare the 2018 catch limits to the 2017 limits by area, fishery, and season,” reads the one-page flyer.

The biggest producers are trawl vessels in the Western Gulf, a fleet that landed 6,861 mt in the A season last year and 2,650 mt in the 2017 B season. Those totals will be 1,543 mt in the A season and 596 in the B season this year.

Central Gulf trawlers are suffering a similar fate: catch limits for the A season are 1,275 mt in 2018 compared to 6,933 mt last year. That fleet is allowed 1,233 mt for this year’s B season, compared to 6,708 mt last year.

The flyer covers jig, hook and line, and pot gear throughout the Gulf and includes the breakdown for state catch limits by area. The two most productive areas historically in state waters are the South Alaska Peninsula and Kodiak. Last year’s catch limit for the South Peninsula (jig and pot gear combined) was 10,887 mt and for Kodiak was 5,523 mt.  This year, it is 2,425 mt and 1,015 mt respectively.

The smallest fishery is the Central Gulf jig fleet, which got 331 mt last year. This year, the combined total for A and B season will be 61 mt.
