News
Crayfish Market size is set to grow by USD 2.26 billion from 2024-2028
Growing demand for aquaculture-based fish varieties is driving market growth, with a trend towards demand for processed and packaged crayfish. Key market players include Acadia Crawfish Co. LLC, Alfocan SA, and more.
West Michigan groups continue fight to control invasive red swamp crayfish
Officials in West Michigan are working on the removal of red swamp crayfish, which was found for the first time in Vicksburg in 2017. Since then, the Barry, Calhoun, and Kalamazoo Cooperative Invasive Species Management Area (BCK CISMA) and Gun Lake Tribe have teamed up to manage the population.
Join Dr. Jared Homola of the U.S. Geological Survey Wisconsin Cooperative Fishery Research Unit to learn how genetic tools are revealing biological and environmental factors that could lead to red swamp crayfish's spread. The webinar is scheduled for Thursday, Sept. 12 at 9AM.
Loyola University Chicago physics students help combat invasive crayfish in Great Lakes
Dr. Robert Polak and Dr. Reuben Keller from Loyola University Chicago have been collaborating on a project to examine the effectiveness of electrical barriers against invasive invertebrates, including the red swamp crayfish.
ICC: Reminder to complete the five-year plan impact feasibility rankings
The ICC is currently prioritizing projects for 2025 based on an impact feasibility analysis. We ask that you review and rank each project's impact and feasibility based on your expertise by September 17. Click on the link above to find the Google spreadsheet and instructions.
Managing invasive crayfish through chemical treatments can be a complex process. To support managers, Michigan DNR has provided resources to help navigate chemical treatment permits and protocols. This includes a guide on constructing Booms for pesticide applications. You can find the resources at invasivecrayfish.org/products under “Manager Resources”.
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.
