Following the report of a Grass Carp angled from a private lake, a joint multi-agency response with Fisheries and Oceans Canada and the Ontario Ministry of Natural Resources and Forestry results in the capture of 10 Grass Carp, two of which are fertile. An additional Grass Carp is captured by a commercial fisherman in Canadian waters of Lake Erie.

The University of Toledo and USGS confirm that the eggs collected in the Sandusky River in 2015 are Grass Carp eggs.
