#DYK the USGS Great Lakes Science Center has provided scientific information for restoring, enhancing, managing, and protecting living resources and their habitats in the Great Lakes region since 1927? Learn more: https://t.co/Tgxto2XrqT. #SciComm https://t.co/Jpqe31ME2n

Many thanks to @EthanBakerMI, Chair of the GLFC, for his continued advocacy and leadership! Baker can be seen on Fox 17 and Fox 2 Detroit, speaking on issues and potential risks that the sea lamprey control program may be facing after 70 years of successful control. #sealamprey

Don't forget to join us TOMORROW at 12:30p EST for the next #CoregonineSciSeries webinar where Corbin Hilling and Robin Debruyne from USGS will discuss the effects of ice cover on reef habitat and hydrodynamics. Register here: https://t.co/zRUTcOhUxG #GreatLakesSci https://t.co/Fvcqii9EsO

Don't forget to join us this Thursday, April 3 at 2p for the next Technoscience Thursdays webinar! #GreatLakesSci #TechInnovation

An analysis of salmon derby data vs cisco recruitment shows Chinook salmon size dramatically increasing 2 & 3 yrs after cisco recruitment events in Lake Superior. Coming off a historic 2022 recruitment, a 39lb fish was caught in 2024 and bigger ones could be in store for 2025. https://t.co/iWH7f1eag2

In the spirit of winter ending, come learn about the effects of ice cover on reef habitat and hydrodynamics! Join us for the next #CoregonineSciSeries webinar on Friday April 4, at 12:30PM EST for a presentation by Corbin Hilling (USGS). Register here: https://t.co/zRUTcOisne https://t.co/AzRRlMM7xg

Agencies around Lake Huron are teaming up to sample larval and juvenile whitefish along beaches and nearshore zones to understand why fewer young fish are surviving to adulthood. Less food available in clearing waters, sporadic ice cover, predation, and more may be at play. https://t.co/rp1GmCVRst

Total phosphorus concentration was highest in February and zooplankton biomass was as high in January as in July in the nearshore of southeast Lake Michigan in 2024, highlighting the importance of winter ecology in Lake Michigan. #2025LakeCmtes https://t.co/cI0h40Gg1L

US Fish and Wildlife Service study finds high survival of Chinook salmon & steelhead stocked in west & south Lake Michigan, respectively; estimates wild production (figure); & shows offshore refuges source lake trout to nearshore fisheries. #2025LakeCmtes https://t.co/jth4TbY4sL

Chinook salmon size is declining and catch rate is on an increasing trajectory relative to previous years. These early indicators suggest predator-prey balance is shifting to lower relative prey abundance. #2025LakeCmtes https://t.co/i0ErYYwohN

During 2024, two wind- and solar-powered un-crewed surface vehicles equipped with hydroacoustic samplers ran transects throughout Lake Superior (see below). Abundance of the massive 2022 cohort of ciscoes, now age-2, will be estimated. #2025LakeCmtes

#DYK the #sealamprey lineage dates back nearly 500 million years and has survived multiple mass extinction events? Read more: https://t.co/zU4UfbQJpA& https://t.co/E1q5NNmZN1. 📷 (L) Robert Gess, Creative Commons; (R) GLFC. https://t.co/TGJbY0jbxu

Big news! The Minnesota DNR discovered a shore-spawning population of coaster brook trout in Lake Superior – the first in MN waters. Genetic analysis is next to uncover their genetic origin. A huge win for long-term conservation efforts! #2025LakeCmtes https://t.co/ykWKRbV8VA

Lake Ontario biologists are on the hunt for lake trout spawning habitats. Using acoustic telemetry, this binational team led by Alex Gatch (USGS) has identified lake-wide spawning sites and behaviors (video below), never-before-seen in Lake Ontario. #2025LakeCmtes https://t.co/FXFKSZ08Ny

Happy 75th anniversary to Hammond Bay Biological Station! Learn more about the rich history that the station has played in controlling invasive #sealampreys, restoring #GreatLakes #fisheries, and protecting our way of life in the Great Lakes region: https://t.co/9i5MTdRZu7. https://t.co/3bN7AeeguQ

Fisheries scientists used acoustic telemetry to study movements of yellow perch (Perca flavescens) in Lake Erie’s western basin from fall 2022 to fall 2024. Only 4 of the 158 tagged fish moved east of the Islands region, towards the central basin. #2025LakeCmtes https://t.co/iASlomq5mM

The Habitat Task Group continues to refine Lake Erie’s Priority Management Areas. This information lends to identifying priority areas for habitat assessment projects like the assessment of Hardy Point Reef near Fairport, OH. https://t.co/ODT7rAZtfO

Lake Erie’s sport and commercial walleye fisheries remained exceptional in 2024. The great fishing is likely to continue in the coming years. Learn more at: https://t.co/7vD5jXEBl4 #2025LakeCmtes https://t.co/sxQenb3fe6

What happened when sea lamprey control agents couldn’t treat streams in 2020? A banner year for lamprey – fish wounding and lamprey numbers surged. Thankfully, resumption of normal treatment effort had the opposite effect. Watch for the full study here: https://t.co/Upi3KTi0BB https://t.co/CaSOtXpyyf
