New Zealand mudsnails have now been found twice in Wisconsin – most recently in Badger Mill Creek, near Madison. They’re the size of a corn kernel, but they can outcompete native species. In extreme cases…
“We’ve seen densities of over 500,000 mud snails per square meter,” states Matt Krueger, Restoration Director of the River Alliance of Wisconsin.
He says mudsnails can seal off their shells, and survive being eaten by birds and fish. And they can live out of water for weeks…
“…because they’re able to completely close themselves off and retain some of that moisture inside.”
When stuck to an angler’s boots, mud snails may live ‘til the next fishing trip. So cleaning all gear between trips can help stop the spread of these sneaky snails.
