Dear ICC Members,
Welcome to the March edition of the Monthly Snap! Watch out for crayfish on St. Patrick’s Day- forget to wear green, and they’ll pinch you harder than a leprechaun.🍀 As always, you’ll find the regular collection of invasive crayfish literature and news below.

Invasive Dupes, Part 2: Crayfish vs. Crayfish — Seeing Double
In honor of National Invasive Species Awareness Week, WTTW is posting daily “dupes”- invasives that can easily be confused with native species. They examine the rusty (Faxonius rusticus) and virile (Faxonius virilis) crayfish and describe their key characteristics.
Invasive Crayfish Threaten Native Species: Illinois Takes Action During National Awareness Week
Discover the ecological battle between native and invasive crayfish species in North America, as Illinois leads the fight against non-native competitors. Learn about the threats posed by invasive crayfish and the conservation efforts spearheaded by researchers and communities.
The cloning crayfish conundrum: A threat to the Great Lakes ecosystem
While not in the Great Lakes -- yet -- its ability to outcompete native species make the marbled crayfish (Procambarus virginalis) a significant risk to the Great Lakes.
Foes or food? Foraging for Great Lakes invasive species
Many invasive species, from garlic mustard to grass carp, were deliberately introduced to the United States because they were once a valuable food source. Michigan Sea Grant shares a few examples below for your culinary inspiration.
Research reveals hope for managing invasive red swamp crayfish
Originally from the southeastern U.S., the red swamp crayfish (Procambarus clarkii) has become an unwelcomed world traveler. Here in the U.S., they are commonly spread by unsuspecting aquarium-hobbyists or biology teachers releasing the unwanted pet into their backyard ponds and rivers. Despite the destructive nature of this species, the U.S. Fish and Wildlife Service hasn't given up the fight.
Minnesota DNR classifies 13 invasive plants, animals as prohibited
Environmental regulators have classified a dozen aquatic plants, fish and invertebrates as prohibited invasive species in Minnesota- one being the invasive marbled crayfish (Procambarus virginalis).
What you need to know about the invasive crawfish in Texas
Last year, the Texas Parks and Wildlife Department (TPWD) put out an ominous message warning Texans to be on the lookout for a new, invasive arrival: the Australian redclaw crayfish (Cherax quadricarinatus). The main threat they could pose stateside is by altering native habitats and vegetation, competitively excluding native crawfish from food and shelter, and preying upon native fish. But are they really cause for concern?
Lowveld ecosystem under threat of crayfish
Just as redclaw crayfish (Cherax quadricarinatus) have become a major marine problem globally, this invasive species have now also found their way into the Lowveld’s waters by way of the Komati and Crocodile rivers.
Flamingo Land: Hatchery hopes to protect endangered crayfish
Work has started on the facility at Flamingo Land near Malton with hopes of housing captive-born crayfish by spring 2024 and bringing in wild females with eggs by summer 2025.
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.
