News
Rusty crayfish are frequent sightings on Chicago beaches. Reuben Keller and his lab at Loyola University Chicago are researching their ecological impacts and supporting ongoing efforts to control their spread.
Invasive crayfish species in Texas waters causing concern for wildlife
The invasive Australian red claw crayfish was seen pervading southern Texas waters, specifically the Rio Grande Valley. Texas Parks & Wildlife officials are concerned that the crayfish species is spreading quickly. Watch this PBS show about the crayfish in Texas.
St. Louis County board approves funding for the fight against invasive species
The St. Louis County board of commissioners granted preliminary approval of state funds for 8 projects to prevent the spread of aquatic invasive species, including rusty crayfish.
Download and reprint the Great Lakes Almanac to Invasive Crayfish
The Great Lakes Almanac to Invasive Crayfish, an outreach product designed to support identification and reporting of invasive crayfish in the pet industry, is available for download and reprint in 4 languages on the ICC website. More information can be found at invasivecrayfish.org/almanac.
This selection of invasive crayfish information is collected by the Invasive Crayfish Collaborative, a program convened and facilitated by Illinois-Indiana Sea Grant and the Illinois Natural History Survey with funding from the Great Lakes Restoration Initiative.
