Alaska Fish Factor

Tiny cod fish are reappearing around Kodiak.

Researchers aim to find out if it is a blip, or a sign that the stock is recovering after warming waters caused the stocks to crash.

Alaska’s seafood

industry was shocked last fall when the annual surveys showed cod stocks in the Gulf of Alaska had plummeted by 80 percent to the lowest

levels ever seen. Prior

surveys indicated large year classes of cod starting in 2012 were expected to produce good fishing for six or more years. But a so called “warm blob” of water depleted food supplies and wiped out that recruitment.

“That warm water was sitting in the Gulf for three years starting in 2014 and it was

different than other years in that it went really deep and it also lasted throughout the winter. You can deplete the food source pretty rapidly when the entire ecosystem is ramped up in those warm temperatures,” explained Steven Barbeaux with the Alaska Fisheries Science Center (AFSC) in Seattle.

This summer researchers at Kodiak saw the first signs of potential recovery with beach seine catches of tiny first year cod that are born offshore and drift as larvae into coastal grassy areas in July and August.

“A lot can happen in

that first year of life that we would like to learn more

about to predict whether or not these year classes are actually going to survive,” said Ben Laurel, a fisheries research biologist with the AFSC based in Newport, Oregon whose specialty is early survival of cold water commercial fish species.

Laurel’s team, which

includes scientists from the University of Alaska/

Fairbanks, has been studying the early life history of Pacific cod in waters around

Kodiak every year since 2005. They documented changes in what he calls “young of the year” fish throughout the warm water event

through 2016. Right afterwards, they saw no first-year cod but Laurel said things might be taking a turn for the better.

“In 2017 the ocean temperatures started to get back to normal and we did see signs of some fish, which is good because we hadn’t seen fish earlier,” he said. “In 2018 we also are seeing some young fish. But again, we’re just looking at one year in one area and it might not be reflective throughout the Gulf, so we are not sure what it means.”

Laurel is taking the tiny cod back to the Oregon wet lab where they will run tests on survival conditions.

“Do they have the likelihood of making it to adulthood just like those fish before the warm water blob? We just don’t know,” he explained. “We don’t have much data on cod during the winter and we can fill that gap in the lab. We can run them through a simulated over winter experience at different temperatures and see what the consequences are of them being a certain size or having certain food available, or what sort of conditions do they need to survive a whole overwintering experience,” he explained.

The cod study this summer also is expanding to more nearshore areas of Kodiak, along the Alaska Peninsula and the eastern Gulf. Laurel credited the AFSC with “really responsive reactions to this drastic reduction in the population,” and adding “more eyes and effort” to understand what happened to the cod stocks.

The research, he said, will provide a window into what might be expected with a changing climate.

“It is kind of a dress rehearsal for what is to come,” he said. “We can’t expect things to stay as they are, and we need to understand these processes and be proactive. I’m encouraged but also nervous about what’s in line for the future. Everybody should be braced for uncertainty.”

Net hack challenge – An Alaska Net Hack Challenge is being planned for September 8 and 9 in Kodiak and Anchorage. The goal is to identify potential opportunities for using the tons of old plastic fishing nets piled up in landfills and storage lots across the state, and develop new items from the materials. The nets can weigh from 5,000 to 20,000 pounds each.

The challenge is based on the Circular Ocean program in the U.K. and Iceland that “aims to inspire enterprises and entrepreneurs to realize the hidden opportunities in discarded fishing nets.” The Alaska hack is sponsored by Grundens, Alpar and Saltwater, Inc.

“The goal is to change how people look at nets and ropes, not as a waste material but as a raw material that can be used in many ways,” said Nicole Baker, founder of http://www.netyourproblem.com and organizer of the event along with the Alaska Ocean Cluster Initiative.

“Socks, water bottles, cell phone cases, carpets, bathing suits, sneakers, sunglasses, skateboards, rugs, bowls,

frisbees, even 3-D printing and injection molds. People are

becoming so creative about finding ways to reuse

these plastic products,” Baker said.

The Alaska challenge is aimed at artists, students,

designers, business owners, engineers, recyclers and anyone interested in designing new products out of the materials.

“On the first day of the challenge we will show presentations about the context and scale of the issue, the type of materials available, and some businesses that have been implemented already,” she explained. “On the second day, teams will get together and use the material and design a prototype, either physically or on a computer, that will be presented to judges to get their feedback.”

A video link will connect the two locations and judges will score the projects on creativity, usefulness and scalability and follow the development over six months.

“That will be supported by the Alaska Ocean Cluster Initiative which has several programs to assist with making small businesses and startups commercially viable,” Baker said.

“If Alaska gets on board, it could be another revenue stream,” added Brian Himelbloom, a retired University of Alaska seafood specialist who is organizing the Kodiak net hack challenge with an assist by the Alaska Marine Conservation Council.

“There are a lot of creative people in Kodiak,” he added, pointing to the Alaska Rug Company that uses fishing nets and ropes to make handwoven doormats, pot holders, baskets, bowls, signs, and more at their remote home at the decommissioned Port Bailey Cannery. The company was recently featured in HGTV magazine.

Himelbloom said the groups also will reach out to local schools to attract “youngsters who are thinking about going into business.” They also are creating a net hack tool kit for remote communities interested in having their own challenges.

The events will take place at the Makerspace Building in Anchorage and at the Kodiak Marine Science Center. Visit http://www.alaskaoceancluster.com to register to attend.

Meanwhile, Nicole Baker also will be in Kodiak in late August to coordinate a fishing net recycling program. It will mirror a first effort last year in Dutch Harbor that sent 40 nets weighing 240,000 pounds to a company called Plastix in Denmark where they were melted down, pelletized and resold to manufacturers of plastic products.

A second shipment also is being planned at Dutch Harbor and Baker said she also has been contacted by people in Juneau, Homer, Seward and other Alaska communities who want to develop net recycling programs.

The Alaska Net Hack Challenge and the recycling program have attracted the attention of Senator Lisa Murkowski.

“It was my first letter from a Senator’s office,” Baker said. “I was very excited.”

Fish watch - Alaska’s total salmon catch has topped 88 million fish – over 48 million are sockeyes and nearly 42 million of the reds are from Bristol Bay. Fishing is winding down there but lots of salmon is still being hauled in elsewhere, albeit slowly in most regions.

The Dungeness fishery in Southeast is ongoing with a summer harvest pegged at 2.25 million pounds.

Golden king crab opened along the Aleutians on August 1 with a 6.3 million pound harvest, an increase of nearly one million pounds for the first time in 200 years.

Halibut fishermen have taken 56 percent of their nearly 20 million pound catch limit. For sablefish, 47 percent of the nearly 26 million pound quota has been taken. Both fisheries close November 7.

Fishing for cod, rockfish, flounders, pollock and other whitefish continues in the Bering Sea; likewise, in the Gulf where pollock fishing will reopen on August 25.

The Alaska Board of Fisheries has set an August 15 deadline to receive agenda change requests for its upcoming meeting cycle. 

The board will take up fisheries at Bristol Bay, the Alaska Peninsula, the Arctic Yukon Kuskokwim, Aleutian Islands and Chignik from November through March. A special two-day meeting on Pacific cod takes place in early October.

Finally, more genetically modified Atlantic salmon grown in Panama has made its way to undisclosed markets. Last summer, Massachusetts-based biotech firm AquaBounty sold its first five tons of “Frankenfish” to undisclosed Canadian customers. The manmade fish grows three times faster than normal salmon.

AquaBounty received FDA approval this year to raise its AquAdvantage salmon at its new land-based Indiana facility, but is currently prevented from importing its genetically tweaked salmon eggs from Canada due to an “Import Alert” pending the issuance of final labeling guidelines.  “We anticipate the import alert to be lifted in the second half of this year,” CEO Ronald Stotish said in a press release.
