October 30, 2020 — For the Yurok people, who have lived at the mouth of the Klamath River for generations, the spring run of Chinook salmon (Oncorhynchus tshawytscha) is a welcome—and nutritious—relief from winter. But as the fish have dwindled to just a fraction of their original numbers, Indigenous groups there are pushing to have them protected by the Endangered Species Act. New research, which suggests genes play only a small role in distinguishing the spring salmon from their fall-run cousins, may call into question the need for such a designation.
The rivers of the Pacific Northwest used to teem with two waves of Chinook: those that arrived in March or April, and those that came 6 months later, swimming from the sea to their upriver breeding grounds. Although technically the same species, the spring-run and fall-run fish have some “iconic differences,” says Eric Anderson, a molecular geneticist at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center. Spring salmon are smaller, fattier, and less sexually mature than fall fish. They also swim further upriver to breed.
To tease out the genetic basis of those differences, Anderson and colleagues teamed up with Yurok fishers living at the mouth of the Klamath River in northern California. Together, they examined 500 fish as they started their upstream journeys in all four seasons. The researchers measured the size of each fish, assessed its fattiness and reproductive status, and took samples of its DNA. The researchers gathered similar data from other rivers.
Past studies have shown that a small region of the salmon chromosome 28 contains two genes, GREB1L and ROCK1, that vary between spring and fall salmon. Anderson and his colleagues did further genomic studies, sequencing the whole genomes of 160 fish in the hopes of linking the two genes to the spring and fall traits. The data set is “impressive” and the work unique says Sheela Phansalkar Turbek, an evolutionary biologist at the University of Colorado, Boulder, who was not involved with the work.

The annual migration of Chinook salmon up West Coast rivers from the ocean has enriched ecosystems, inspired cultures, and shaped landscapes. Yet the timing of their migration is controlled by one small section of their genome, according to research published this week in Science.
This is the first time scientists have linked a single gene region to such an influential difference in a vertebrate species. For salmon, it determines whether they return upriver from the ocean in spring or fall. This has crucial implications for other species that rely on them for food. First author Neil Thompson of the University of California Santa Cruz and NOAA Fisheries’ Southwest Fisheries Science Center said that this small genetic difference can have a major effect on a complex pattern of migration and reproduction.
Fish migrating upriver in spring may access habitat such as higher elevation tributaries. These habitats become less accessible to Chinook salmon migrating later in the year when stream flows decline. The result is that fall-run Chinook salmon remain lower in the watershed without continuing up into the tributaries.
However, the construction of dams in the West blocked spring-run Chinook salmon from much of their original spawning habitat. This contributed to the listing of several spring-migrating fish under the Endangered Species Act. Fall-run Chinook salmon on the West Coast are generally more abundant.
The scientists identified the gene region influencing migration with whole-genome sequencing. Then, they scientists examined the genetic pattern in more than 500 Chinook salmon caught by the Yurok Tribe in the Klamath River estuary. They analyzed the effects of variation in this genetic region on migration timing and other physiological traits.

October 30, 2020 — As the seafood industry responds and adapts to the effects of covid-19, NOAA is working to fill in some information gaps in its economic impact surveys.
One of those gaps is West Coast and Alaska seafood harvesters — folks on the East Coast have already been surveyed.
Ocean Strategies is aggregating information and delivering it confidentially to NOAA, helping to ensure West Coast harvesters are included in this important work to document impacts to the commercial fishing industry.

Companies already approved to provide IFM services in IFM years 2020 and 2021 do not need to apply again in order to provide services in 2021.
Refer to the bulletin for more information on what to include in an application.
Approvals will cover IFM year 2021. If we receive any applications under this announcement, we will notify service providers of our preliminary determination as soon as we have completed our reviews. Final decisions will be published in the Federal Register.
October 29, 2020 — The following was released by NOAA Fisheries:
All vessels 65 feet (19.8 meters) or longer must travel at 10 knots or less in certain locations (called Seasonal Management Areas or SMAs) along the U.S. east coast at certain times of the year to reduce the threat of vessel collisions with endangered North Atlantic right whales. The purpose of this mandatory regulation is to reduce the likelihood of deaths and serious injuries to these endangered whales that result from collisions with vessel.Because vessels of all sizes can strike a whale, NOAA Fisheries also encourages vessels less than 65 feet in length to help protect right whales by slowing to 10 knots of less within active SMAs as well.

Give Right Whales Room
North Atlantic right whales are on the move along the Atlantic coast of the U.S. NOAA is cautioning boaters and fishermen to give these endangered whales plenty of room. We are also asking all fishermen to be vigilant when maneuvering to avoid accidental collisions with whales and remove unused gear from the ocean to help avoid entanglements. Commercial fishermen should use vertical lines with required markings, weak links, and breaking strengths.
Right Whales in Trouble
North Atlantic right whales are protected under the U.S. Endangered Species Act and the Marine Mammal Protection Act. Scientists estimate there are only about 400 remaining, making them one of the rarest marine mammals in the world.
North Atlantic right whales are NOAA Fisheries’ newest Species in the Spotlight. This initiative is a concerted, agency-wide effort to spotlight and save marine species that are among the most at risk of extinction in the near future.
In August 2017, NOAA Fisheries declared the increase in right whale mortalities an “Unusual Mortality Event,” which helps the agency direct additional scientific and financial resources to investigating, understanding, and reducing the mortalities in partnership with the Marine Mammal Stranding Network, Canada’s Department of Fisheries and Oceans, and outside experts from the scientific research community.

Fishermen can sign up for relief through the program from September 14, 2020 to December 14, 2020. Sign up for the Program.
October 29, 2020 — The population of extremely endangered North Atlantic right whales has fallen even further in the last year, the National Oceanic and Atmospheric Administration (NOAA) said Monday.
The agency said that there were only 366 of the whales as of January 2019, down from 412 in January of 2018, The Associated Press reported. But their numbers are likely even lower than that. NOAA Fisheries has documented the deaths or likely fatal injuries of a further 15 whales since, the Conservation Law Foundation (CLF) pointed out.
“These population estimates are devastating,” CLF senior attorney Erica Fuller said in response to the news. “The outlook is grim if we do not act today. We know human activities are decimating this population, what will it take for federal fishery managers to finally take action to protect these magnificent animals?”
October 28, 2020 — The following was released by NOAA Fisheries:
The information collected by observers and at-sea monitors is essential to successful science-based fisheries management. Gathering and recording accurate data while aboard a vessel is challenging work. It’s the first step in a much longer process of validating and integrating the data for use by scientists and managers.
Historically, observers have collected data on paper forms for manual processing, but many programs are moving the entire data collection process to a paperless system. This improves cost and timing efficiencies while reducing potential errors in the data itself. Our Northwest Fisheries Science Center has put a new paperless system to the test, and the lessons learned can inform other projects across the country.
The program has traditionally used paper-based data collection and documentation of fishery catch weights (e.g., groundfish, shrimp, midwater species) for trawl and fixed-gear, rod and reel, longline, and other gear types.
In the paper-based process, the information is calculated, entered into an offline database while at sea, and then synced to an online database once on land. Then, observer program staff review the data, consider edits or corrections, and if necessary, require resubmissions before the data becomes available to end-users.
To address their goals to streamline the traditional workflow, the observer program has been developing a system that includes data entry into a handheld device. This eliminates error-prone processes like transcription and calculation, and enables electronic data archiving.
“Improvements to our data collection process resulted in faster data turnaround and catch quota updates for vessels that participated in our program,” says Jason Eibner, a former observer who has worked for 12 years at the Hatfield Marine Science Center in Newport, Oregon, part of our Northwest Fisheries Science Center.
“We realized that a paperless electronic data collection system would help us work even more efficiently by removing the most tedious and time-consuming steps. At the same time, we’re increasing data accuracy and providing our observers with some deserved down time in the field,” added Eibner.
