Crayfish Corps Resource Brief 2023
The Crayfish Corps is a volunteer program in which members of the public join park staff in working to suppress the population of non-native invasive rusty crayfish (Faxonius rusticus) in Valley Forge National Historical Park. From May through September, individuals, families, scout troops, school groups, community organizations, and corporate groups have assisted park staff in capturing and removing rusty crayfish from Valley Creek.
Douglas County commissioners approve hiring crayfish harvester
In the fall of 2023, Douglas County Land and Resource Management staff were notified that Signal Crayfish had been discovered in Lake Winona. The Aquatic Invasive Species prevention coordinator for Douglas County, Justin Swart, asked the Douglas Board of Commissioners to allow Land and Resource Management to enter into a contract with a commercial harvester to do a Signal Crayfish survey and trapping of the crayfish. By doing this, Swart said it is expected to decrease the number of crayfish in the lake during the spring spawning season.
Meet the Folks Fighting Invasive Species in Ontario
It's been more than 30 years since the Invading Species Awareness Program began in Ontario. From invasive zebra mussels to grass carp and emerald ash borer- they are the frontline when it comes to protecting Ontario from harmful species. Field reporter Jeyan Jeganathan explains how there's a new creepy crawly threat looming in our waters - the marbled crayfish.
Two restaurants in Yamagata Prefecture, Japan, have found a delicious way to combat invasive species while serving up tasty meals. At the Seiten no Kaze ramen shop in Tsuruoka, you can slurp on Zarikko Paitan Ramen featuring red swamp crayfish powder and boiled crayfish.
Lake Pueblo State Park installs new gates to permit late boat departures
Lake Pueblo State Park adopted a policy that will allow boaters to exit the water after hours. “We are trying to accommodate them while maintaining the highest defense possible to prevent aquatic nuisance species from entering the lake,” Joe Stadterman, park manager for Lake Pueblo State Park, said.
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.
