From the New York Times:

Asian carp, the voracious, nonnative fish whose arrival near Lake Michigan is threatening to cause havoc in the Great Lakes, are now setting off strife on land as well.

In an urgent effort to close down Chicago-area passages that could allow the unwanted fish to reach Lake Michigan, the State of Michigan is suing the State of Illinois and other entities that govern the waterways here. Minnesota, Ohio and Wisconsin have filed documents in recent days supporting Michigan’s move, and Indiana says it will soon do the same.

The new rift between these Midwestern states, which would reopen a nearly century-old legal case in the United States Supreme Court over Great Lakes waters, comes at a particularly sensitive moment — just as the numerous entities with interests in the Great Lakes had united in what lakes advocates consider some of their most significant progress in decades.

When participating in a crayfish participatory science activity, be sure to snap plenty of photos of any crayfish you catch or observe. Not only is it a great way to capture the fun and excitement of the day, but it also helps document the species present. To ensure accurate identification by scientists, it’s important to provide clear photos from multiple angles. Dorsal (top), lateral (side), and ventral (underside) views of the crayfish should always be photographed.To learn more about the specific features to highlight in your photos visit the link in bio or InvasiveCrayfish.org/Management/#Community
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
