Wild capture fisheries depend on healthy populations of the target fish species.  Non-native species can outcompete and reduce biomass of desirable fish and shellfish species.   The Arizona Cooperative Fish and Wildlife Research Unit lab has tested means to identify the most damaging nonnative species and remove nonnative species from waters.  We have used bioenergetics computer modeling procedures to identify the most important fish predators of desirable fish in an over 100-mile-long river section
