eDNA could play a bigger role in stock assessments

September 5, 2026 — A bipartisan group of U.S. senators is backing legislation that would expand the use of environmental DNA (eDNA) in federal fish stock assessments, potentially giving fisheries managers another tool to collect more frequent and comprehensive data.

According to Cornell University, the Fisheries Science Modernization Act would direct NOAA to test and validate eDNA technologies for use alongside existing fishery assessment methods. The bill is led by Senator Murkowski, R-Alaska, and Senator Whitehouse, D-Rhode Island, co-chairs of the Senate Oceans Caucus, and has eight republican, democratic, and independent co-sponsors.

NOAA currently develops stock assessments using methods including research vessel surveys, bottom trawls, acoustic sonar, longlines, and commercial fishing data. Those assessments ultimately help regional fisheries managers establish annual harvest levels.

The legislation calls for NOAA to expand its use of eDNA to increase survey coverage and frequency while potentially lowering costs.

Bipartisan fisheries management law would expand eDNA use

September 1, 2026 — Bipartisan legislation introduced this month by the co-chairs of the U.S. Senate Oceans Caucus relies on environmental DNA (eDNA) techniques pioneered by Cornell researcher David Lodge, professor of ecology and evolutionary biology and past director of the Cornell Atkinson Center for Sustainability.

The Fisheries Science Modernization Act would direct the National Oceanic and Atmospheric Administration (NOAA) to incorporate eDNA tools into their assessment surveys of fish stocks – assessments that inform how many fish can be harvested by commercial and recreational fishers. Eight Republican, Democratic and independent senators co-sponsor the legislation, and multiple fishing industry and environmental protection organizations support it.

“When I started testing eDNA 17 years ago, I was interested in detecting rare species, such as emerging invasive species and endangered species,” Lodge said. “The focus of this legislation is quite different. Here, it’s not just about detecting whether a Pacific hake exists, it’s about estimating how many hake there are, based on how many distinct pieces of hake DNA you can find. It’s pretty astonishing to me that we in the scientific world working on eDNA have come this far, this fast.”

NYS teachers take on microplastics with snail-inspired robot

August 11, 2026 — On a rainy morning in late July, Professor Sunny Jung asked a group of New York state schoolteachers to consider the biology of the aquatic snail.

With only one foot, the snail can move and feed, and they do it with an efficient undulating motion that can draw in particles from a distance 10 times greater than their body length.

“They are very efficient at pulling in water from the surface without sucking in the bulk fluid,” said Jung, professor of biological and environmental engineering in the College of Agriculture and Life Sciences, at a workshop for New York state teachers offered by a team of researchers and staff at Cornell, New York Sea Grant (NYSG), Princeton University and the University of Michigan. Now in its second year, the program gives teachers the tools to apply Cornell research in their classrooms, with lesson plans and hands-on materials they can share with their learners.

The workshop’s lessons center on the application of Jung’s research to a problem of increasing concern: the proliferation of microplastics in waterways. Inspired by the undulating movement of the snail, Jung designed a simple robotic system that can pull surface water in and filter microplastics out. With a team of collaborators, the group put the mechanism on a robot they named Mollusca and created both lab-scale prototypes and a build-your-own version for schools.

As Jung presented the research, the wires, circuit boards, motors and many 3D-printed components of the Mollusca robots lay in disassembled piles on a back table. Before day’s end, the teachers would build the robots, test them in a kiddie pool filled with small pieces of plastic called nurdles, and troubleshoot just like students, just like researchers, turning the conference room in Upson Hall into a makeshift robotics lab.

“The Sea Grant trainings are the best I’ve ever done,” said Emily Colletta, head of the gifted and talented program at North Tonawanda Intermediate School in North Tonawanda, New York, who was attending the workshop for the second time. “They’re super interactive, and it’s always local, which makes it easier to integrate and for the kids to benefit. And they always provide us with hands-on materials we can take back to our classrooms. It’s pretty special.”

New project aims to protect whales while developing offshore wind energy

June 3, 2022 — A new partnership between conservation and renewable energy is coming to Massachusetts.

The Right Wind project, through the combined efforts of the New England Aquarium, Cornell University, and LAUTEC US, aims to help offshore wind developers protect the North Atlantic right whale.

“We’re excited to be starting this project because it gives us an opportunity to develop tools that can help reduce the potential risks of wind energy development to North Atlantic right whales, a critically endangered species that numbers less than 350 individuals,” said Dr. Laura Ganley, an associate research scientist at the New England Aquarium.

Monkfish Research Awards to Improve Understanding of Monkfish Biology and More

July 31, 2018 — SEAFOOD NEWS — NOAA Fisheries and the New England and Mid-Atlantic Fishery Management Councils have announced three new cooperative research projects that will improve the understanding of monkfish biology, as well as how to reduce catch of skates in monkfish gillnet gear. 500 days-at-sea have been set aside by the councils to be awarded to projects that address monkfish research priorities.

Coonamessett Farm Foundation was awarded 296 monkfish Research Set-Aside (RSA) days-at-sea to conduct a 2 years study on determining sex and maturity stage in Southern New England monkfish. Coonamessett Farm Foundation will use ultrasound methods to determine sex and maturity stage. In addition, they will also be conducting hormone analyses to “create a reproductive profile based on sex and maturity stage of monkfish.”

Meanwhile, Cornell University Cooperative Extension of Suffolk County was awarded 303 monkfish RSA days-at-sea to conduct a 2-year experiment evaluating a modified gillnet designed to reduce skate bycatch. The University of New England was awarded 401 monkfish RSA days-at-sea to conduct a 2-year study on monkfish vertebrae and illicia.

NMFS Weighing Privately Funded Assessment of Summer Flounder Stock

February 23, 2018 — For the first time, the National Marine Fisheries Service (NMFS) will consider privately funded science in formulating regulations for summer flounder.

Funded by the Save the Summer Flounder Fishery Fund (SSFFF) and its contributing partners, a groundbreaking sex-structured model created by Dr. Patrick Sullivan of Cornell University was presented in January to the NMFS’ Stock Assessment Workshop in the hope of obtaining a clearer picture of the summer flounder population.

The ultimate goal is to improve the accuracy of the next stock assessment and consequent management advice.

The summer flounder fishery is of vital importance to the recreational and commercial fishing sectors along the Atlantic Seaboard and its continued health is a key concern among stakeholders.

Dr. Sullivan, who developed the model with renowned fisheries researcher Dr. Mark Maunder, presented the findings to NMFS staff at the Summer Flounder Stock Assessment Workgroup at Woods Hole, Mass.

During the past 10 years, Dr. Maunder has been working on fluke population research for SSFFF and his work has been highly successful in developing important findings that have helped stave off significant quota reductions.

Based on 10 years of research conducted by the SSFFF team of scientists, the group now believes that the present stock assessment does not represent the best available science. A new and comprehensive stock assessment model which incorporates the latest findings is considered critically important in guaranteeing the survival of this vital fishery.

High-Tech Satellite Tags Give Unique View into the Behavior of King Salmon

November 28, 2017 — Cornell University, New York Sea Grant, and charter boat captains have teamed up on a high-tech mission to learn more about the behavior of King Salmon in the Lake Ontario ecosystem.  They’re already getting valuable information from pop-off satellite tags attached to the fish.

New York Sea Grant Fisheries and Ecosystem Health Specialist Jesse Lepak narrated a video that shows the tagging process with the help of charter captains.  It took about a month to tag 10 fish starting in early July.

“Once the fish are landed, they’re put in a Styrofoam cradle to help keep them calm, and lake water is pumped across their gills so they can  breathe.  The fish are then tagged with a monofilament harness that connects the tag to the fish.  The harness is crimped, and the excess monofilament is cut off.  The tagged fish is ready to go.”
