“Grass carp, a plant-eating species of the invasive Asian carp family, have also been found spawning in Lake Erie and its many tributaries…Though fears over invading Asian carp have largely centered on bighead and silver carp — which gulp down large amounts of plankton, the all-important food-source foundation for a healthy aquatic ecosystem — the new study suggests conservationists should pay attention to grass carp too.Grasses are also an important nutritional source for native fish species, and as its name suggests, grass carp could prove detrimental in that department.The U.S. government has already spent upwards of $200 million trying to slow the encroachment of Asian carp into the Great Lakes. Many worry their growing presence will turn the Great Lakes into one giant carp pond — ruining ecological diversity and the multi-billion dollar fishing industry in the region. Regional authorities remain in discussion with federal agencies over further mitigation efforts.”

Trash talk + trivia + Great Lakes science at a brewery on Earth Day.
Science Sips: Trash Talk about Chicago Waterways brought together researchers, curious locals, and trivia bingo to talk about what’s really floating in Lake Michigan and what we can do about it.
Thank you to everyone who came out and to @sketchbookbrew for hosting!
Located in Washington, D.C., the Sea Grant Knauss Fellowship provides a unique educational and professional experience to graduate students who have an interest in ocean, coastal and Great Lakes resources, and in the national policy decisions affecting those resources. This is a one-year fellowship open to any student, regardless of citizenship, who is enrolled toward a degree in a graduate or professional program on the day of the deadline.
Students enrolled at an Illinois or Indiana university or college should submit their applications through Illinois-Indiana Sea Grant by emailing Angela Archer at amcbride@purdue.edu. Students in surrounding states without a Sea Grant program should contact the National Sea Grant College Program at oar.sg.fellows@noaa.gov for a referral.
Application deadline: June 3, 2026.

Freshwater science meets comic con. 🎮🌊
We brought the Great Lakes to @c2e2 in Chicago, and thousands of visitors discovered that food webs, invasive species, and aquaponics can be just as wild as surviving an alien ocean.
(Yes, we used Subnautica as a gateway to Great Lakes science. Yes, it worked.)
What topic do you think got people the most excited?
