The Illinois-Indiana Sea Grant has started a new campaign against invasive species. The aquatic species arm of the campaign is Release Zero.
I particularly appreciate the point that it’s hard to be a responsible pet owner when so many providers don’t know or provide scientific names. There are hundreds of species of crayfish with different invasive potential, so just selling “crayfish” is irresponsible. There is a great need for quick, high quality ways of identifying species in the pet trade.
Marmorkrebs are not featured on the main webpage, but are species of concern for the Great Lakes, as the project’s Twitter account points out.
Wild marbled crayfish populations are established across Europe and elsewhere. They have NOT been found in the Great Lakes! 🙌 Aquarium owners, anglers and others can help keep it that way.
We need way more education on this, so I hope this campaign is very successful!
