New global forecasts of marine heatwaves foretell ecological and economic impacts

April 22, 2022 — Researchers have developed global forecasts that can provide up to a year’s notice of marine heatwaves, sudden and pronounced increases in ocean temperatures that can dramatically affect ocean ecosystems.

The forecasts described in the journal Nature could help fishing fleets, ocean managers, and coastal communities anticipate the effects of marine heatwaves. One such heatwave, known as “the Blob,” emerged about 2013 in the northeast Pacific Ocean and persisted through 2016. It led to shifting fish stocks, harmful algal blooms, entanglements of endangered humpback whales, and thousands of starving sea lion pups washing up on beaches.

“We have seen marine heatwaves cause sudden and pronounced changes in ocean ecosystems around the world, and forecasts can help us anticipate what may be coming,” said lead author Michael Jacox, a research scientist at NOAA Fisheries’ Southwest Fisheries Science Center in Monterey, California, and NOAA’s Physical Sciences Laboratory in Boulder, Colorado.

Marine heatwave forecasts will be available online through NOAA’s Physical Sciences Laboratory. The researchers called the forecasts a “key advance toward improved climate adaptation and resilience for marine-dependent communities around the globe.”

Seabirds, Fishing Vessels Supplied Data to Support Ocean Research During Pandemic

November 15, 2021 — The COVID-19 pandemic curtailed daily life for millions and idled much of NOAA Fisheries’ marine research. Scientists turned to unusual collaborators: seabirds in the isolated Farallon Islands off the California Coast near San Francisco.

With most NOAA ships at the dock, the researchers realized that their nearly 40-year time series of conditions off the California Coast was in jeopardy. However, they also realized that long-term surveys of seabird diets could help validate what little other data they had. The birds sampled the same anchovy, rockfish, and other forage fish populations that research vessels do in normal times. Crews from longtime NOAA collaborator Point Blue Conservation Science have logged what fish the birds were catching as they returned to the islands to feed their chicks.

Leveraging Help From Fishermen

Scientists at NOAA Fisheries’ Southwest Fisheries Science Center realized as the pandemic set in during early 2020 that their offshore surveys faced long odds. They contracted a commercial fishing vessel and trained fishermen on how to use their specialized research net and sample the catch. The fishermen then delivered those samples to the survey team. They analyzed the catch in open lab spaces wearing masks and other protective gear as required for social distancing during the pandemic. That turned out to be one of very few fisheries surveys on the West Coast in 2020.

Between pandemic limits and harsh weather, however, the vessel collected only about 25 percent of the data that researchers would typically get from such surveys. They also needed other data to help fill out and confirm the rest of the picture.

Key Southern California Rockfish Species Survive Capture Over the Longer-term Following Release

October 26, 2021 — Deep-water rockfish reeled quickly to the surface often emerge from the water with eyes and organs bulging like alien beings—due to the sudden change in pressure—a condition known as barotrauma.

Now new research shows that if fishermen return fish to their natural depths quickly, their bodies return to normal and they can survive any ill effects. The research focused on cowcod and bocaccio, two historically overfished rockfish species caught off the coast of Southern California. They were returned to the depths using special descending devices that are now standard for many recreational fishermen.

Prior to this research and the use of descending devices, it was widely assumed that deep-dwelling rockfish could not survive catch and release due to their extensive barotrauma injuries. “We now know that these deep-dwelling rockfish species can survive,” said Nick Wegner, a research scientist at NOAA Fisheries’ Southwest Fisheries Science Center and lead author of the new research. “That is good news for the fish, and good news for the fishermen who go to the trouble of trying to release them properly.”

The research was published in ICES Journal of Marine Science. Scientists used acoustic transmitters to track released cowcod and bocaccio for up to a year on an underwater seamount approximately 40 miles off the coast of San Diego, California. They were captured at depths of 75 to 183 meters, or about 250 to 600 feet. By tracking the fish for extended periods, researchers found that most fish survived beyond 30 days. Of those fish that died, 40 percent died beyond the typical 2-day tracking window used in many fish survivorship studies.

California Current Fish Surveys Resume with 3-Month Assessment of Sardine, Anchovy, and Mackerel

July 22, 2021 — The following was released by NOAA Fisheries:

NOAA Fisheries has begun an ambitious assessment of small pelagic fish reaching from the Canadian border to the southern tip of the Baja Peninsula, in cooperation with Mexico, which will help determine how many fish can be caught off the West Coast.

The COVID-19 pandemic had idled surveys for sardine, anchovy, and other species of small coastal pelagic species (CPS) off the West Coast since 2019. Small pelagic species are important ecologically and provide food for larger fish, such as tunas. The new assessment resumes regular CPS  surveys by collecting data from NOAA Ship Reuben Lasker, commercial fishing vessels equipped with acoustic technology, and autonomous Saildrones.

The Lasker left San Diego on July 6, becoming the centerpiece of the 3-month survey. It will cover thousands of miles in U.S., and Mexican waters. NOAA Fisheries scientists are coordinating efforts with federal fisheries agencies in Mexico and Canada, providing a science foundation for future decisions on fishing levels and seasons.

“Organizing and coordinating this survey was a tremendous feat of collaboration,” said Kristen Koch, Director of the Southwest Fisheries Science Center in La Jolla, which is leading the survey. “Collecting data across all three countries will provide a valuable foundation for management of these important transboundary species.”

The Lasker will survey coastal pelagic fish along transects in the California Current, quantifying the fish with echosounders. These instruments include an advanced new model that can for the first time also measure the velocities of fish as they swim relative to the ship. The measurements will help to understand whether and how fish respond to survey vessels and if those reactions affect the quality of data on the numbers and distributions of fish.

Peter Kuriyama, Research Mathematical Statistician

May 4, 2021 — The following was released by NOAA Fisheries:

Meet Peter Kuriyama, a research mathematical statistician with the NOAA Southwest Fisheries Science Center.

What is your key responsibility?  

I do stock assessments for coastal pelagic species. The results of these assessments inform fisheries management on the west coast of the United States.

Where did you grow up?

Solana Beach, California.

What is your educational background?  

I did my undergraduate degree at UC Santa Barbara and Ph.D. at University of Washington. My dissertation mainly looked at the impact of catch share implementation on the U.S. West Coast groundfish fishery.

What are your hobbies?    

I like surfing, cooking, reading, and basketball.

Is there a book, quote, or person that influenced you to be the person that you are today?  

My parents and grandparents are strong influences. A couple recent books, The Color of Air by Gail Tsukiyama and Interior Chinatown by Charles Yu, have been impactful. The Color of Air tells a story of a Japanese immigrant family working on sugarcane plantations in Hawai’i. Japanese immigrants came to Hawai’i thinking that they would work on plantations for a couple of years, but plantation owners prevented them from returning home and forced them to continue working. My ancestors worked on these plantations in Hawai’i and likely had similar experiences. Interior Chinatown excavates Asian-American stereotypes in pop culture. I regularly listen to the podcast Time to Say Goodbye, which discusses Asian America among many other topics.

What does Asian American and Pacific Islander Heritage Month Month mean to you? What does being a career civil servant mean to you?

To be honest, I didn’t even know that May was Asian American and Pacific Islander Heritage Month. Unfortunately, I think this year it will be featured more prominently than in previous years. I think months of awareness are good, and hopefully they motivate people to keep learning and acting year-round.

While there are often challenges to the work, I feel fortunate to be able to do science that helps to sustainably manage fisheries.

Pacific Council Rejects Sardine Stock Projection; Approves Reduced Fishing Levels for 2021

April 15, 2021 — In a surprising turn, the Pacific Fishery Management Council’s Scientific and Statistical Committee rejected a Southwest Fisheries Science Center catch-only sardine biomass projection when the Council met this week.

NMFS field surveys were cancelled in 2020 due to the COVID-19 pandemic and no real directed fishery in the U.S. has been conducted on sardines since 2015. The catch-only projection was supposed to be the basis for the fishery’s management measures for the season from July 1, 2021, to June 30, 2022.

Pacific Sardine Landings May Shift North as Ocean Warms, New Projections Show

February 25, 2021 — The following was released by NOAA Fisheries:

Pacific sardines are a small but sometimes numerous fish closely intertwined with California’s fishing history. A new study linking climate change and the northern sardine stock fishery shows that they may shift north along the West Coast as the ocean warms.

A climate-driven northward shift by sardines could cause a decline in landings of the northern sardine stock by 20 to 50 percent in the next 60 years. These changes would affect historic California fishing ports such as San Pedro and Moss Landing, according to the new research published in Fisheries Oceanography. The study did not examine whether southern sardine stock would also shift northward, potentially offsetting this decline in landings. In turn, landings at northern port cities such as Astoria, Oregon, and Westport, Washington, are projected to benefit.

Researchers examined three possible “climate futures.” The warmest had the most pessimistic outcomes, with total sardine landings in all West Coast states declining 20 percent by 2080.

Understanding climate-driven shifts in habitat helps predict impacts on landings

The study translates environmental shifts into possible impacts on fishing communities and coastal economies. Sardines have historically gone through “boom and bust” changes in their population. Their numbers off the West Coast have remained low in recent years, with the West Coast sardine fishery closed since 2015. This research does not project changes in the abundance of sardines. Instead, it shows that climate-driven shifts in their habitat may have a significant impact on landings at historically important ports.

“As the marine environment changes, so too will the distribution of marine species,” said James Smith, a research scientist with the University of Santa Cruz affiliated with NOAA Fisheries’ Southwest Fisheries Science Center. “But linking future changes in the distribution of species with impacts on the fishing fleet has been challenging. Hopefully our study can provide information about potential impacts in coming decades, and thereby inform strategies to mitigate these impacts.”

CALIFORNIA: Fishful Future: A New Collaborative Community Project to Move San Diego Toward a Zero Waste Seafood Supply Chain

February 9, 2021 — The following was released by Fishful Future:

The Fishful Future project is a newly launched collaborative effort joining seafood processors, fishery scientists, local fishermen, and renowned chefs. Supported by an award from the competitive National Marine Fisheries Service’s Saltonstall-Kennedy Grant Program, the project explores opportunities for San Diego’s fishing, seafood processing, and culinary industries to move toward a zero-waste seafood supply chain by fully using each fish.

Around 50 percent of each fish by weight generally remains after processing for the fillet market. This half of the fish is often discarded, or sold for cents on the pound, despite the valuable proteins and nutrients contained for a wide range of applications.

To encourage the use of the entire fish, the team explores the value in each part. The Fishful Future project addresses local food security by empowering home chefs to prepare less familiar secondary cuts with culturally diverse recipes, partnering with community groups in food insecure areas, and working with project chefs to develop new restaurant presentations.

The project also brings together entrepreneurs from a broad range of businesses in a new collective approach to increase sustainability by using what is currently considered to be waste. Seafood processing byproducts find valuable applications in bait, fertilizer, pet foods, bio-pharmaceutical, bio-medical, and artistic fields.

“More complete use of the fish means greater economic value and opportunity for fishermen, processors, and everyone who enjoys seafood,” said Dave Rudie, Catalina Offshore Products founder and president. “We owe it to the fish and to our customers to make the most complete use of each fish that is taken out of the ocean.”

Leading the culinary approaches are four San Diego chefs: Davin Waite, Karen Barnett, Christina Ng, and Rob Ruiz. These chefs are not only vocal, active contributors in their community but also wildly creative, committed to respecting their ingredients, and embody the goals of the project in their cookery and daily lives.

The multidisciplinary team is led by Catalina Offshore Products and scientists at the NOAA Southwest Fisheries Science Center, with partners including the Tuna Harbor Dockside Market, the Port of San Diego, Iceland’s Ocean Cluster, and Oregon State University’s Seafood Research & Education Center.

“The only way we can succeed is by doing this together,” said Sarah Mesnick, from NOAA Fisheries Southwest Fisheries Science Center, who is a scientific advisor in the effort. “All partners in the seafood and product supply chain bring their own expertise and experience to the project, so that together we look at these valuable species in a new, holistic, and more sustainable way.”

Inquiries are welcome from parties interested in joining this effort toward a Fishful Future. Learn more by visiting fishfulfuture.com and following along on Instagram @fishfulfuture.
