After a day spent catching, stunning and netting as many fish as possible, no invasive aquatic species were found in Morrow Lake. According to scientists from the Michigan Department of Natural Resources, at the time of the survey catfish, bass, bluegill and golden redhorse were identified, all species native to the lake. This is no small feat due to AIS’s presence in the U.S., summer recreation and the area’s recent dredging due to the 2010 Kalamazoo River oil spill (a pipeline operated by Canada-based oil company Enbridge). Local officials are excited with the good news, and will continue surveying the lake frequently in hopes of catching invasive species before they become a problem. That is, if they’re ever introduced at all.
