Invasive Fish

An invasive species is an introduced species that has established itself and threatens the diversity and/or stability of a native species or environment. WARC researches the basic biology and environmental tolerances of these plant and animal species to provide resource managers with the ecological facts they need to help mitigate and control these problematic species. This work includes invasive fishes like the lionfish and Asian carp.
