Alaska: Gov. Bill Walker calls for federal disaster declaration for Pacific cod fishery

March 13, 2018 — Gov. Bill Walker and Lt. Gov. Byron Mallott signed a letter last week asking the federal government to declare the 2018 Pacific cod fishery in the Gulf of Alaska a disaster.

That could make the fishery eligible for federal relief funds, although who specifically would receive money would be figured out later.

It follows a decline in stock and a deep cut to the 2018 Pacific cod quota in the gulf.

According to the letter, the value of the 2018 Pacific cod harvest is looking at a more than 80 percent drop in revenue from the five-year average. Barbara Blake, senior adviser to Walker and Mallott, said crossing that 80 percent threshold makes the fishery eligible for a disaster declaration.

Blake said the letter will go to the secretary of commerce for a decision.

“How we’ve seen this come about in the past is that request goes in along with other natural disasters, and that’s how we end up getting the appropriations for that, is they roll it into natural disasters like hurricane relief and things of that nature,” Blake said.

Southeast Alaska Longliners Become Bathymetric Cartographers to Avoid Bycatch

March 12, 2018 — SEAFOOD NEWS — A desire by Southeast Alaska longliners to avoid rockfish bycatch in 2009 evolved into a high-tech effort to collect bathymetric data for use in detailed seafloor maps. The maps would ultimately help fishermen avoid bycatch and sensitive habitats like coral and sponge areas. Next week, these detailed and data-rich maps will be available to the fishermen who helped make them.

For the last decade, members of the Fisheries Conservation Network (FCN) used scanning software to map the halibut and sablefish grounds. At the end of each fishing season, FCN members shared the data with ALFA, where it was combined into one database, then used to create the enhanced maps and sent back to the fishermen to continue adding data to.

ALFA Executive Director Linda Behnken, in an interview with KCAW radio in Sitka, said the result is one of the most complex bathymetric databases on the eastern side of the Gulf of Alaska.

“One hundred and forty million data points have been contributed,” she said. “It’s been a lot of years getting to this point. We’re really excited about the level of detail we have now and the quality of the maps.”

Alaska: Bering Sea Trawl Cod Fishery May Have Been Shortest Ever, as High Prices Attract Effort

February 20, 2018 — SEAFOOD NEWS — The Bering Sea federal trawl cod fishery closed in what may be record time on Feb. 11, just 22 days after the Jan. 20 opener, according to National Marine Fisheries Service Biologist Krista Milani in Unalaska/Dutch Harbor.

“I wouldn’t be surprised if it’s the shortest ever,” and certainly for as long as she’s had the job going back to 2009.

While the Bering Sea cod quota is down 20 percent from last year, Milani said other factors are at play. She pointed out that in a previous year, with an almost identical quota, the season remained open for about six weeks, ending the second week of March in 2010.

This year, the A season Bering Sea cod trawl quota is 24,768 metric tons, and in 2010 it was 24,640 mt.

“The bigger thing is the price is good, and there’s a lot of interest in it,” Milani said.

“I think there’s a lot of reasons,” including fishermen feeling a need to build catch histories to qualify for future Pacific cod fishing rights, if a rationalization program is adopted for cod in the Bering Sea, she said.

“I think there’s some fear it could go to limited access,” Milani said.

The North Pacific Fishery Management Program is now considering a plan to restrict the number of boats eligible to fish for cod in the Bering Sea.

The fish council floated ideas to limit catcher vessel participation in the Bering Sea cod fishery, including controversial catch shares or individual fishing quotas, during a December meeting in Anchorage.

IFQs are not among alternatives the council is considering. The purpose and need statement, approved unanimously, includes limiting trawling to vessels actually fishing cod in various years between 2010 and 2017.

This would create a limited entry program within a limited entry program. Bering Sea cod fishing is already limited to boats with licenses. Some of those boats don’t usually participate, but can when prices are high or stocks are low in their usual fisheries.

Brent Paine, the executive director of United Catcher Boats, said something needs to be done to regulate fishing in the congested “Cod Alley.” He accurately predicted a three-week season in 2018 in the area offshore of Unimak Island.

“This is the last unrationalized fishery in the eastern Bering Sea,” Paine said. “If you don’t do anything, we’re all going to be losers.”

While Paine said the NPFMC’s present majority is unsympathetic to rationalization, calling it the “R word,” he said that may change in the future.

Rationalization opponents see IFQs as privatization adding another barrier to entry into the fishing world, while supporters call it a reward for investment with benefits including substantial retirement income.

Milani said Tuesday it was still too early to say how many trawlers participated, as there were vessels still delivering cod to processing companies, and perhaps some trawlers delivering loaded nets to offshore motherships. The last count had 55 in the federal cod fishery, compared to 57 last year, she said, expecting this year’s final count will be higher.

The number of boats is hard to track in-season, as many go back and forth between cod, pollock and other fisheries, although there are some that only fish cod, Milani said.

The depressed cod stocks in the Gulf of Alaska probably also contributed to this year’s fast pace, she said. Gulf cod stocks are way down, far worse than the smaller decline in the Bering Sea, an 80 per percent decline from last year.

Earlier in the season, Milani said the number of Gulf boats coming into the federal Bering Sea cod fishery was smaller than expected.

The Gulf cod crash appears to be having a greater impact in the state cod fishery, with 32 small boats registered on Tuesday, up from 24 last year in the Dutch Harbor Subdistrict. The state waters fishery is limited to boats 58 feet or shorter fishing within three miles of shore and using only pot gear.

The Dutch Harbor Subdistrict total catch on Monday was 11.4 million pounds caught in pots from a total quota of 28.4 million pounds. The pot cod fishery is expected to continue for another 14 to 16 days, according to Alaska Department of Fish and Game Biologist Asia Beder in Unalaska.

In the Aleutian Islands Subdistrict state waters fishery, with a quota of 12.8 million pounds, Beder couldn’t release precise total catch numbers because of confidentiality rules when there’s fewer than three processors. She said the fleet has caught somewhere between 25 and 50 percent. There’s only one processor, in Adak, Golden Harvest — formerly Premier Harvest, she said. And she could also say there were eight small boats fishing cod in the Aleutian subdistrict, all in the Adak section.

In the Aleutians, cod boats are allowed up to 60 feet in with various gear types, although longliners are limited to 58 feet.

In Bering Sea crab fisheries, the 50 boats dropping pots for opilio snow crab had made 134 landings for 10.9 million pounds or 58 percent of the total quota. The cumulative catch per unit of effort for the season is an average of 161 crab per pot, according to shellfish biologist Ethan Nichols of ADF&G in Unalaska.

In the Western Bering Sea Tanner fishery, 28 vessels had made 66 landings for 2.1 million pounds, with the quota nearly wrapped up at 85 percent.

In the Eastern Aleutian District, two small boats harvesting bairdi Tanner had landed over 75 percent of the total quota of 35,000 pounds, Nichols said.

The EAD is open this year only in the Makushin and Skan Bay area, and that’s where the Tanners are from that sell for $10 each by local fisherman Roger Rowland at the Carl E. Moses Boat Harbor in Unalaska.

Alaska cod quotas light up a loophole

February 16, 2018 — The fallout of shifts in Alaska cod quotas has sparked another scramble among the region’s cod fishermen. Overall P-cod quota is down, but the Aleutian Islands saw a small uptick, which led more boats to target the area in the A-season this year. The allocations, however, have had some unintended consequences.

For some background, in the wild and harsh fishing environments of the Bering Sea, Aleutian Islands and Gulf of Alaska, a 60-footer qualifies as a small boat. A fleet of these smaller pot-cod boats typically fishes inshore waters and relies on deliveries to the remote Bering Sea island of Adak to run their Aleutian operations.

The remoteness of the region, however, has historically made running a processing plant there logistically implausible without guarantees of landings. This led the North Pacific Fishery Management Council to set aside 5,000 tons of cod quota that must be processed in the remote Aleutian Island community of Adak rather than off-loaded to offshore factory processors, as the larger catcher vessels — sometimes referred to as the Amendment 80 fleet after the legislation that put them into operations — do in the offshore fishery.

“This harvest set-aside provides the opportunity for vessels, [Aleutian Islands] shoreplants, and the communities where AI shoreplants are [located]to receive benefits from a portion of the AI Pacific cod fishery,” according to the council.

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.
