As Bering Sea ice melts, Alaskans, scientists and Seattle’s fishing fleet witness changes ‘on a massive scale’

September 16, 2019 — Derek Akeya hopes for calm waters and a lucrative catch when fishing from a skiff in the Bering Sea that surrounds his island village.

But on this windy late summer day, waves toss about the boat as Akeya stands in the bow, straining to pull up a line of herring-baited hooks from the rocky bottom.

Instead of bringing aboard halibut – worth more than $5 a pound back on shore – this string of gear yields four large but far less valuable Pacific cod, voracious bottom feeders whose numbers in recent years have exploded in these northern reaches.

“There’s a lot more of them now, and it’s more than a little bit irritating,” Akeya says.

The cod have surged here from the south amid climatic changes unfolding with stunning speed.

For two years, the Bering Sea has been largely without winter ice, a development scientists modeling the warming impacts of greenhouse-gas pollution from fossil fuels once forecast would not occur until 2050.

Advancing Innovative Technologies to Modernize Fishery Monitoring

July 24, 2019 — The following was released by NOAA Fisheries:

Thanks to recent technological advances in computer processing hardware, machine vision cameras, and open source software tools, fishery researchers at the Alaska Fisheries Science Center are now taking the next steps in developing electronic monitoring systems and image processing applications that would automate data collection from images captured onboard vessels. Eventually, the goal of real-time image processing is to support scientific data that provide greater certainty in managing ocean resources and sustainable fishing practices.

In 2018, the North Pacific Fishery Management Council and NOAA Fisheries implemented an electronic monitoring program to provide a monitoring alternative for longline vessels, where accommodating an observer can be logistically difficult.

“This program’s integration of electronic monitoring data directly into the catch estimation data stream marked a milestone,” explains Farron Wallace, former senior research fisheries biologist at the Alaska Fisheries Science Center and now director of the Southeast Fisheries Science Center Galveston Laboratory. “However, the systems are not yet able to collect detailed data on individual fish length and weight as an observer does—data that are critical to support stock assessment modelling and catch estimation.”

Additionally, although useable observer data in the North Pacific are either uploaded to a database several times daily via satellite or uploaded at the end of a trip, vessels using electronic monitoring systems store imagery on hard drives, which are then mailed after the trip to video reviewers who process and extract key information. This time-consuming procedure can significantly delay data upload, a concern when data timeliness is essential for fisheries management—particularly for those management programs that have prohibited species catch limits, maximum retainable allowances, or other in-season quota restrictions.

Rock, Coral, Sponge: Does One Beat the Rest as Fish Habitat?

July 18, 2019 — The following was released by NOAA Fisheries:

Rockfish love structure. More seafloor structure means more rockfish. But while the amount of structure matters, the type doesn’t, a new NOAA fisheries study finds.

Rocks, corals, and sponges proved to be equally desirable real estate for individual rockfish, given a choice. However, rockfish were most frequently associated with sponges—the most commonly available structure in the Alaska study area.

These findings will help resource managers in their efforts to effectively manage rockfishes, deep-sea corals, and sponges.

“We found that Alaska rockfishes are more abundant when vertical structures such as rock, coral, and sponges are present. Corals and sponges add structure to areas with minimal rocky formations, creating a more complex habitat for rockfish,” explains Chris Rooper of the Alaska Fisheries Science Center, who led the study. “Unfortunately, some human activities and potentially climate change can have negative effects on the survival of coral and sponge ecosystems, thereby impacting both the distribution and abundance of rockfish species in Alaska waters.”

As sea ice melts, fish are showing up farther north off Alaska. A federal fishing trip will investigate if they’re sticking around.

May 31, 2019 — Last fall, Adem Boeckmann, a commercial fisherman who lives outside Nome, pulled up some of the pots he uses to fish for crab on the ocean floor.

“Had 10 24-inch cod in each pot,” Boeckmann said. “I never saw anything like that.”

Cod, which is used in fish sticks and fish and chips, is caught in huge numbers by commercial boats in the Bering Sea. But not near Nome – typically, the fish is caught hundreds of miles south. Historically, the ecosystem where Boeckmann fishes has been centered on the ocean floor, without big populations of large fish.

Federal scientists are setting off on their own Bering Sea fishing trip this summer, to investigate whether observations like Boeckmann’s – bolstered by the government’s own previous findings – could be indicators of profound shifts in the ocean ecosystem driven by global warming. The results of the summer fieldwork could have major implications for the Bering Sea’s billion-dollar fisheries, as well as for Alaskans who live, hunt and fish along the Arctic coast.

“Is this part of an environmental shift, where with the warming, the northern Bering Sea is going to become a top-down system?” asked Lyle Britt, a federal fisheries scientist who will spend more than a month at sea this summer. “Or, is this more like an ephemeral trend that just happened because we had an unusually warm year, and things will reset? We don’t really know.”

The surveys are done by the Seattle-based Alaska Fisheries Science Center, an arm of the National Oceanic and Atmospheric Administration.

Seaweed Farmers in Alaska Gear Up for Large Haul

May 29, 2019 — The largest commercial harvest of seaweed in Alaska is taking place this month.

Blue Evolution, a California-based company that cultivates, harvests and distributes Alaska-grown seaweed, is expected to haul in up to 200,000 pounds from waters near Kodiak Island within the next two weeks. Previous harvests have been a fraction of that size, but, as the mariculture industry grows in Alaska, Blue Evolution is also expanding.

Working with local resident farmers, the company produces seed from wild seaweed plants and grows them into kelp starts in an onshore hatchery at the federal government’s Alaska Fisheries Science Center Kodiak Laboratory. Blue Evolution then supplies seeded string to local farmers who plant them onto longlines in late fall, cultivate their crops during winter and harvest in spring.

The company is collaborating with the University of Alaska and Alaska Sea Grant on seaweed research aimed at developing cost-effective cultivation methods for several native species. Seaweed farming is a growing, multibillion-dollar industry worldwide and presents a new economic opportunity for coastal Alaska.

“It suits my family because we set gillnet for salmon during the summer and supplement our income with seaweed farming during winter,” said Lexa Meyer, who co-owns and operates Kodiak Kelp Co. with her husband.

Scientific Teams Set Out to Track Unprecedented Changes in the Eastern Bering Sea

April 24, 2019 — Over the past five years, winter atmospheric conditions that influence the Bering Sea have been markedly different from previous years. Strong, warm winds out of the south—sometimes lasting more than 30 days—have forced sea ice northward. Water temperatures have been warmer than normal and NOAA scientists have observed some significant changes in marine species. They are in unexpected places, in larger or smaller numbers than normal, and many are thin. Scientists are also seeing changes in the numbers of young fish that are reaching maturity.

“We predict that changing environmental conditions will continue to affect the marine food web structure—and potentially the productivity of the northeastern Bering Sea shelf ecosystem,” said Robert Foy, Director, Alaska Fisheries Science Center. “This is going to be a critical year to survey this region.”

Beginning in April and continuing through September, NOAA scientists will conduct vessel surveys in the Bering Sea. Four of these are annual surveys that have been conducted for several decades, providing a good basis of data so scientists can detect trends and changes in the ecosystem. Another survey, the northeastern Bering Sea bottom trawl survey, has been fully conducted just two times in the past decade. In 2018, Researchers completed a partial survey of the area. This year scientists intend to conduct a full survey to further establish a baseline of data for longer-term monitoring of changes that are taking place.

How Science Can Help Managers Anticipate and Respond to Climate Change to Keep U.S. Fisheries Sustainable

March 28, 2019 — The following was released by NOAA Fisheries:

The Bering Sea ecosystem, which has experienced unprecedented changes in recent years, provides a real-world testing ground for a new strategy to help marine resource managers anticipate and respond to climate change. The new strategy, developed by NOAA Fisheries scientists, is outlined in a paper published this week. It calls for evaluating existing management measures and developing climate forecasts for various marine areas in Alaska, over different time frames, to promote sustainable fisheries under changing environmental conditions.

“We’re talking about responsive science and management. What’s unique about our approach is that we consider interacting climate, biological, and socio-economic changes and how humans are affected by those changes,” said Kirstin Holsman, lead author, and scientist at Alaska Fisheries Science Center.

According to Holsman, this is important because changes in social conditions can influence how people respond to management measures and, ultimately, their effectiveness.

“We wanted to provide resource managers with a strategy to help them better understand environmental and socioeconomic variability over time, to help them balance tradeoffs and anticipate tipping points when the transition to a new ecosystem or social state occurs. At that point, it becomes about adaptation.”

US shutdown delays NOAA surveys that influence groundfish TACs

February 7, 2019 — Some of the important summer research surveys that the US National Oceanic Atmospheric Administration (NOAA) conducts each year off the shores of Alaska to estimate the health of key commercially caught groundfish stocks like pollock and Pacific cod could face delays due to the recent partial government shutdown, officials said.

In a report to the North Pacific Fishery Management Council, NOAA’s Alaska Fisheries Science Center, said that the shutdown that sent most of its staffers home from Dec. 22, 2018, until Jan. 25 has already affected one research cruise, a winter pre-spawning acoustic survey of pollock stocks in the Gulf of Alaska.

“Unfortunately, due to the delay in starting the survey, the first two legs (in the Shumagin Islands and outer Kenai regions) will not be conducted,” science center staffers wrote in a report to the NPFMC.

Blob 2.0 is bad sign for Gulf of Alaska groundfish

December 11, 2018 — Fish heavily impacted by a three-year marine heatwave in the Gulf of Alaska may be headed for round two. Commonly referred to as the blob, warmer waters between 2014 and 2017 were blamed for a dramatic decline in Pacific cod and are thought to have negatively impacted other species such as pollock.

The North Pacific Fishery Management Council set catch limits for several groundfish species in the Gulf of Alaska Thursday afternoon. Before members set those limits, Stephani Zador with the Alaska Fisheries Science Center updated the council on the latest trends in the Gulf.

“Importantly, starting in September, we are officially in another heatwave in the Gulf of Alaska,” she explained.

Pacific cod populations in the Gulf plummeted as their food source decreased during the blob, but after waters returned to somewhat normal temperatures in 2017, Zador said cod body conditions improved.

“All the groundfish in our survey that we sampled, except for cod, had poor body condition. So, they were skinnier per length than average,” Zador said. “That was a sign we saw consistently through the heatwave and indicates that cod were able to pop back up.”

The council slashed the total allowable catch by 80 percent last year and lowered it slightly again this year in order to allow the species to rebound. Pacific cod populations in the Gulf are expected to stabilize in the coming years, but another marine heatwave, or blob 2.0, could hamper any progress.

Pollock have also suffered poor recruitment in recent years, but Zador said larva abundance was above average in 2017. However, much like cod, another heatwave is not a good sign.
