While much of the press about a carp invasion in the Great Lakes has focused on the bighead and silver varieties of Asian carp, a new study is showing that grass carp are making their way into and threatening the Lakes as well. 
 
From UPI.com
“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.”

Who says “Back to School” means back indoors? While the weather is still warm, take your students on an outdoor science adventure by exploring crayfish in your local waterways.The Invasive Crayfish Collaborative invites grades 2-12 educators to take part in a hands-on participatory science activity. By catching, identifying, and reporting crayfish species in your area, students contribute valuable data that helps scientists better understand where native and invasive crayfish live.Check out what other educators have found and get involved: inaturalist.org/projects/great-lakes-crayfish
Come round up some rusty crayfish and help remove this #invasivespecies from the Fox River at the 7th Annual Rusty Rodeo. Join us at this FREE event and help collect, identify, and remove rusty crayfish from the river using aquatic nets and buckets. Prizes are given to the participant who collects the most, the largest, and the smallest rusty crayfish. Learn more about native and invasive aquatic species at educational pop-up exhibits.Participants will need to provide their own supplies. We suggest bringing an aquatic net, a bucket, and clothes and shoes you don’t mind getting dirty. This is a partnership program with: Forest Preserve District of Kane County, St. Charles Parks & Recreation Department, Fox Valley Park District, and Friends of the Fox River. No registration required.More info: https://kaneforest.com/upload/2025RustyRodeoFull-pageFlyer.pdf#CrayWeek #Crayfish #InvasiveSpecies #RustyCrayfish #FoxRive
