NOAA Fisheries Part of International Team to Study Salmon in Gulf of Alaska Under Continuing Warm Conditions

March 13, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries scientists are part of an international team that set sail on April 11. They are studying the impacts of continued warm ocean temperatures in the Gulf of Alaska on Pacific salmon survival.  It has been estimated that one-third of all Pacific salmon spend the winter in the Gulf of Alaska. While reduced in size compared to previous years, the current marine heatwave affecting the Gulf remains one of the top five largest heatwaves on record in the North Pacific in the last 40 years.

“Salmon affect more people culturally, economically, and recreationally than any other fish in the world,” said Doug Mecum, Deputy Regional Administrator for NOAA Fisheries Alaska Region. “This International Year of the Salmon expedition in the Gulf of Alaska expands international salmon research on the high seas to build understanding of how a changing climate may influence salmon ocean habitats, distributions, and productivity.”

Scientists suspect young salmon that can find sufficient food and experience enhanced early marine growth are those that best survive their first winter at sea. The survival of these fish largely determines the size of subsequent adult salmon populations. So, scientists think that environmental conditions have the greatest influence on salmon survival during their first year at sea.

“We know that ocean and climate conditions play a major role in regulating salmon abundances,” said Wess Strasburger, who will serve as chief scientist on the first leg of the survey. “But we don’t have a good understanding of the mechanisms regulating salmon abundances in the ocean.”

NOAA fish study underway on New England offshore wind area

March 12, 2020 — A three-year study of cod and other commercial fish species is underway around New England offshore wind energy sites, part of a National Oceanic and Atmospheric Administration effort to better understand how proposed turbine arrays will affect the environment and fisheries.

With universities and other partners, the agency’s National Marine Fisheries Service in December deployed a Slocum electric glider, a type of autonomous underwater vehicle that has proven highly successful in long-term oceanographic studies.

The glider’s instrument payload includes a hydrophone to detect the sounds of whales and of fish spawning, and an acoustic telemetry receiver to pick up signals from fish that have been captured and released with acoustic tags to track their movements.

Now surveying the area around Cox’s Ledge, the glider is covering an area that includes wind developer Ørsted’s planned South Fork wind energy area south of Rhode Island and east of Montauk, N.Y.

Scientists Collecting Data on Commercial Fish Species in Wind Energy Lease Areas

March 12, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries scientists and colleagues have started a three-year study of Atlantic cod and other commercial fish species in Southern New England. Their goal is to gather baseline data to address how offshore wind development in the region could affect these animals.

An autonomous underwater glider is surveying areas in and around Cox’s Ledge. This includes the South Fork wind energy lease area south of Rhode Island and Massachusetts. The glider has a hydrophone to detect fish spawning sounds and an acoustic telemetry receiver to detect tagged fish. The receiver will identify location and seasonal occurrence of hotspots for key commercial and federally listed fish species.

According to project lead Sofie Van Parijs, there is little information on Atlantic cod spawning specific to Southern New England waters. Cod elsewhere are known to form large, dense spawning aggregations in predictable locations relatively close to shore, where they can be vulnerable to disturbance that might affect spawning success. Van Parijs also heads the Passive Acoustics Research Group at the Northeast Fisheries Science Center laboratory in Woods Hole, Massachusetts.

“Biological sampling will determine the population’s onset of spawning and track growth, maturity, age structure, and other life history parameters,” Van Parijs said. “This information will help inform the starting date for our glider surveys each year. We will tentatively conduct these surveys from December through March this year and for longer periods in the subsequent two years.”

Rare Visitors: Harp Seals in New England

March 12, 2020 — The following was released by NOAA Fisheries:

While we’re used to seeing harbor and gray seals in New England, we occasionally get seal visitors from the Arctic. In late winter, it’s not unusual—though it is rare—to see harp seals on our beaches.

Sometimes well-meaning people come across these seals and, while wanting to help them, do exactly the things that cause these animals stress.

Find out more about these seals, and what you should do — and not do — if you come across one on the beach.

Scallop Research Set-Aside Program Supports 12 Projects for 2020-2021

March 12, 2020 — The following was released by the New England Fishery Management Council:

The Atlantic Sea Scallop Research Set-Aside (RSA) Program will support 12 projects during the 2020-2021 award cycle that address resource surveys, economic impacts of offshore wind development on the scallop fishery, links between environmental factors and scallop meat condition, and many other issues.

The awards were announced on March 11 by the Northeast Fisheries Science Center and the Greater Atlantic Regional Fisheries Office, which both are part of NOAA Fisheries. The funded projects focus on scallop research priorities identified by the New England Fishery Management Council, which established the Scallop RSA Program in 1999 through Framework Adjustment 11 to the Atlantic Sea Scallop Fishery Management Plan. The Council and NOAA Fisheries work together to support research-set aside projects. The Council sets priorities, and NOAA Fisheries manages the RSA competition and administers the program.

Women’s History Month: Talking with Katey Marancik

March 11, 2020 — The following was released by NOAA Fisheries:

My interest in a marine science career really started when I was 9 years old. My siblings and I were playing in the waves at our favorite place in the world—Island Beach State Park, New Jersey. The lifeguards started whistling, making everyone get out of the water. It turned out garbage, including syringes, was washing up on beaches nearby. I was furious! No one messes with my ocean, and no one makes me get out of the water except hunger or my mom. This seemingly small event inspired my fascination with how people use the sea and how things move around in it. Whether it’s garbage washing up on beaches from a barge offshore, or it’s fish larvae moving from a spawning site to juvenile habitat.

I went to college and grad school, working with some amazing men and women in the vast marine biology field. I earned my Bachelor of Science in marine biology from the University of North Carolina, Wilmington. While there, I narrowed my interests while participating in undergraduate honors research studying the movement of fish larvae through Beaufort Inlet in North Carolina. Fish larvae are so diverse in how they look and how they function in their environment. I was hooked—enjoy the pun!

After college, I earned a Master of Science at East Carolina University studying larval fish communities in and around Gray’s Reef National Marine Sanctuary off the coast of Georgia. I then took on a series of research positions, including my current position where I’ve learned more about the amazing early life history of fish.

Now, I’m a contractor working with the talented and dedicated researchers of the science center’s Oceans and Climate Branch. We collect and analyze plankton and hydrographic data to inform how we understand and manage fisheries and protected species. All these years later, I’m still connecting my long-held fascinations with how people use the ocean and how fish larvae move through it.

Second lawsuit filed in at-sea monitoring dispute

March 10, 2020 — A second lawsuit has been filed in a U.S. federal courthouse against a rule, scheduled to take effect Monday, 9 March, that would require Atlantic herring fishermen to pay for independent monitors aboard their vessels.

Seafreeze Fleet LLC and two vessels it owns filed the lawsuit against the U.S. Department of Commerce, the National Oceanic and Atmospheric Administration, and NOAA Fisheries in U.S. District Court in Rhode Island last week. It comes a couple of weeks after New Jersey fishermen filed a similar lawsuit over the rule.

NOAA Fisheries Proposes Atlantic Chub Mackerel Measures

March 9, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries proposes measures adopted by the Mid-Atlantic Fishery Management Council as part of Amendment 21 to the Atlantic Mackerel, Squid, and Butterfish Fishery Management Plan to manage chub mackerel.

Because a directed fishery for Atlantic chub mackerel recently emerged in the Mid-Atlantic, in 2018 the Mid-Atlantic Council implemented initial measures to maintain existing catch levels while it developed a long-term management approach. In the intervening three years, the Council has collected more detailed information on chub mackerel and has developed management measures to help achieve and maintain the sustainability of the chub mackerel resource.

This action would designate essential fish habitat; set catch limits for 2020-2022; and implement an annual catch limit, accountability measures, possession limits, permitting and reporting requirements, and other administrative measures for Atlantic chub mackerel caught from Maine through North Carolina.

For more details, please read the rule as published in the Federal Register.  Supporting analysis for this rule is available on the Council’s website.

The comments due date is April 8, 2020. To submit comments, please use the Federal e-rulemaking portal, or send comments by regular mail to Michael Pentony, Regional Administrator, National Marine Fisheries Service, 55 Great Republic Drive, Gloucester, MA, 01930. Please mark the outside of the envelope, “Comments on the Comments on Chub Mackerel Proposed Rule.”

West Coast Waters Shift Toward Productive Conditions, But Lingering Heat May “Tilt” Marine Ecosystem

March 6, 2020 — The following was released by NOAA Fisheries:

Burgeoning populations of anchovy and a healthy crop of California sea lion pups reflected improved productivity off parts of the West Coast in 2019. However, lingering offshore heat worked against recovery of salmon stocks and reduced fishing success, a new analysis reports.

The California Current Ecosystem Status Report explains that ocean conditions off the West Coast remain unusually variable. This has been the case since the arrival of a major marine heatwave in 2014 known as “The Blob.” NOAA Fisheries’ two West Coast laboratories, the Northwest Fisheries Science Center and Southwest Fisheries Science Center, issue the report each year to the Pacific Fishery Management Council.

“There is not a real clear picture here,” said Chris Harvey, co-editor of the report developed by the two laboratories’ Integrated Ecosystem Assessment approach. The approach integrates physical, biological, economic, and importantly social conditions of the California Current marine ecosystem into the decision-making process. “On the one hand, we have a lot of anchovy out there. On the other hand, we also have a lot of warm water. That is not usually a sign of improved productivity.”

Your virtual crow’s nest: Drones in commercial fishing

March 6, 2020 — According to legend, the term “crow’s nest” derives from the practice of Viking sailors, who carried crows or ravens in a cage secured to the top of the mast. In cases of poor visibility, a crow was released, and the navigator plotted a course corresponding to the bird’s flight path, which invariably headed toward the nearest land. If the bird didn’t return, it was a sign that land was near. The Bible also tells us that while on the ark, Noah released a raven first, and then doves, to find dry land.

Sailing vessels used a crow’s nest as a vantage point to spot other ships, hazards, land or, in the case of fishing ships, fish schools near the surface, long before radar was invented. Fishermen have always relied on the understanding of the elements to guide them: the water current, its temperature, the direction of the wind and its humidity are important information used to locate fish. Now, drones are bringing some fishfinding technology back above the water.

Modern times have given fishermen new tools to search for fish schools, from the radar or sonar to GPS. Fish shoal and school together because large numbers gives them some kind of protection against some of their natural predators. The same critical mass that provides the safety of numbers also makes them easier to spot.

Drones make it more accessible to search for large quantities of fish or in some cases, large fish. While owners of bigger offshore fishing boats may have the economic means to use technologies like multibeam echosounders, small-boat operators may find that drones are an affordable solution to spot fish schools. Raymarine’s Axiom UAV application is a good example of such a solution, as it brings together the power of advanced marine electronics and advanced unmanned aerial vehicles.
