ABSTRACT: Bighead carp (Hypophthalmichthys nobilis) is an aquatic invasive species expanding its geographic range in the upper Mississippi River Basin, USA. Within systems Bighead carp have invaded, individuals tend to be highly fecund establishing populations possessing the ability to alter native aquatic biota and habitat. The largest tributary to Mississippi River in the State of Minnesota, the Minnesota River, was listed as infested for Bighead carp in 2017.  Understanding the potential suitable habitat availability for Bighead carp throughout the Minnesota River could allow for the development of preventative strategies, mitigating or reducing impacts of population expansion. Potential suitable habitat can be isolated using ecological niche models, such as MaxEnt, which identifies environmental conditions where a species is currently found and detects those conditions elsewhere forecasting a possible environmental range.  After incorporating hydrologic connectivity, MaxEnt models successfully identified a variety of areas susceptible to Bighead carp establishment within the Minnesota River Basin.  Using the MaxEnt modeling results of this study, managers now have areas to focus sampling efforts for prompt detection of Bighead carp and to evaluate potential mitigation practices to prohibit naturalization of these species in the Minnesota River.
