Globally, the spread of invasive species is a threat to the health of the environment and our quality of life. Both invasive species and anthropogenically induced climate change are now considered as the top two threats to our planet’s biodiversity (Vitousek et al. 1997 Science 277: 494-499; Halpern et al. 2008 Science 319: 948-952). Aquatic nuisance species (ANS) are nonindigenous species that affect the diversity or abundance of native species, the ecological stability of infested waters, and/or any commercial, municipal, agricultural, aquacultural, or recreational activities dependent on such waters. ANS may occur within inland, estuarine, or marine waters, such as zebra mussels, New Zealand mud snails, European green crabs, hydrilla, Eurasian water milfoil, didymo, snakehead, and lamprey eels. The term ANS is often used interchangeably with aquatic invasive species (AIS). The United States invests more than $120 billion per year in damage and control costs to combat invasive species (ANSTF 2012). As the world trade network continues to grow, the number and frequency of introduced species are expected to increase. Therefore, it is important to understand the ecology associated with ANS, as well as investigate control options to address ANS issues.
