Technical Center for Aquatic Nuisance Species (TCANS)


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.


TCANS is composed of a team of experts currently conducting research on aquatic biota. TCANS provides sound science, innovative technology and knowledge in the ecology and management of aquatic nuisance species in lakes, reservoirs, rivers, marinas, and coastal areas. The mission of the Technical Center for Aquatic Nuisance Species is to improve environmental and human health, as well as economic wealth through collaborative research and offering timely training to students and the public.
