At Take Your Child to Work Day, @StateDept and Great Lakes Fishery Commission hosted a lamprey booth to show how the United States is working together to protect America’s $5.2B Great Lakes fishery. Keeping invasive sea lampreys in check, because lampreys suck! Special thanks to @DeputySecState for stopping by to meet the kids and the lamprey!

Looking for summer fun? Do you live in—or plan to travel to—the NE Michigan area? #sealampreys are visiting the GLs Maritime Heritage Center (NOAA TBNMS) one day each month from April-Oct in 2026. Schedule a trip to see these creatures and enjoy the interactive exhibits! #scicomm

#DidYouKnow Dr. Ellen Marsden coined the name "quagga mussel" & led groundbreaking research that transformed our understanding of #invasivespecies in the #GreatLakes? Her research continues to shape aquatic ecosystem management globally. uvm.edu/rsenr/profile/… #SciComm #DYK

After 70 years, sea lamprey control finally has its own theme song! 📷 Check out this retelling of the sea lamprey story in the Great Lakes — this time as a sea shanty. Thank you to the Rockin' Hops for their original performance in La Crosse last week! facebook.com/share/v/1CsryX…

If you've ever wondered what the Great Lakes look like below the surface, you won't want to miss this film. It won't premiere until 2028, but in the meantime, you can check out their live streams! inspiredplanet.ca/hidden-below-l… #freshwater #documentaryfilm #greatlakes @HiddenBelowFilm

#DidYouKnow #invasive quagga mussels in the #GreatLakes got their name from a striped African mammal? Related to zebra mussels, the quagga mussels’ less distinct striping inspired Dr. Ellen Marsden to name it after the quagga, a zebra subspecies. #DYK doi.org/10.1139/f92-166

Mark your calendars! April 30 - May 3, the @freshcoastfilm is coming to @TraverseCity MI, where FishPass is being constructed. Check out the lineup here: bit.ly/4tBqGIJ! You can also have a chance to take a walking tour of FishPass. Sign up here: bit.ly/4csYkuf

And with that, the #2026LakeCmtes Mtgs (LCM) have come to an end. Last wk, fisheries managers, scientists, & the public came together to discuss fisheries data. The US & Canadian Cmtes of Advisors also came together to discuss issues important to the GL fishery. Join us in 2027!

#DidYouKnow the GLFC has a fact sheet for youth with 10 fascinating facts about #GreatLakes #sealamprey? Take a look and share with others! glfc.org/pubs/factsheet… #InvasiveSpecies #SciComm #DYK

Trends in nutrient status indicate that Lake Erie had steady productivity during the 2021–2025 State of the Lake reporting period with a mean Trophic State Index (TSI) of 39.7. TSI is an index that combines phosphorus, Secchi depth, & Chlorophyll-a into one metric. #2026LakeCmtes

Invasive mussels are ~90% of animal biomass on the floor of the lower 4 Great Lakes. The USGS Great Lakes Science Center is pioneering automated computer vision algorithms to detect mussels & estimate density from photos, supporting the SWIM project. More: glc.org/work/swim

Tracking Trout! Researchers are using acoustic telemetry to track adult lake trout around Lake Ontario to find spawning areas and better understand how habitat may be limiting restoration goals. Questions? Contact Alex Gatch (USGS). #2026LakeCmtes

While not all restoration objectives have been met, most indicators are trending upwards for lake trout rehabilitation in Lake Huron. Multiple agencies are cooperating on assessing these populations in both Canadian and US waters. #2026LakeCmtes

New research using acoustic telemetry has revealed 65% of walleyes in Saginaw Bay are spawning in open water while just 35% in rivers. A huge surprise to researchers and this helps explain how the population keeps expanding. Important implications for habitat work. #2026LakeCmtes
