New Zealand mud snails are currently found in New York State in Lake Ontario. They are easily spread on mats of and can pass through the guts of live fish. Control/Management:

They outcompete native snail species reducing Chemical: Research has shown that application ) biodiversity and can be a vector for parasites of Green Clean PRO is an effective way to that infect native snails and fish.
