UPDATE: Invasive snail found in Dane County, could spread

UPDATED Friday, November 15, 2013 --- 9:13 a.m.

SHEBOYGAN, Wis. (AP) -- An invasive snail has been found in a trout stream in Dane County, spurring fears that it could spread to other Wisconsin waterways.

A Sheboygan Press Media report says state wildlife officials are advising outdoor enthusiasts to take precautions to limit its spread.

The New Zealand mud snail was discovered last month in Black Earth Creek, which is popular for trout fishing. The snail is about the size of a grain of sand but it reproduces so quickly that biologists say it could significantly alter the food chain.

They can also spread quickly, for example in a clump of mud on a fisherman's waders. They can survive for weeks without water, so officials ask anglers to freeze their equipment for eight hours or clean and dry their gear thoroughly.

MADISON, Wis. (AP) -- The Wisconsin Department of Natural Resources says scientists have confirmed the invasive New Zealand mud snail has turned up in Dane County.

The DNR says the University of Wisconsin-La Crosse confirmed last month the snail was present in a sample agency biologists took from Black Earth Creek last year during routine monitoring for aquatic invasive species. The find marks the first time the creature has been discovered in an inland Midwestern stream.

The snail is the size of a grain of sand and has a black and brown shell. They out-compete native insects that serve as food for fish and other aquatic life.

The snails have previously been found in the western states and in the Great Lakes.
