| Comments | Procambarus clarkii were established in three ponds in 2009. An eradication program was started in November by Wisconsin DNR of the same year with sodium hypochlorite and continued in 2010. Physical measures included bank manipulation, placement of bank barriers and in some cases, filling of the pond were untaken. Major construction and treatment efforts were completed in September of 2013 (Bunk and Van Egeren 2016). The ponds may still hold a very small population of the red swamp crayfish as a single emaciated individual was found in summer 2017. Wisconsin DNR is continuing to monitor the ponds for the next several years for additional Red Swamp Crayfish sightings (Maureen Ferry, WDNR personal communication 2017). |
