ABSTRACT: Invasive Silver Carp and Bighead Carp have spread widely throughout the Mississippi River Basin, at time reaching tremendous densities. Although these fish consume resources and alter the ecosystems they inhabit, they also serve as potential prey for native piscivores. In portions of the Illinois River, juvenile Asian carp constitute the majority of small ( < 100 mm TL) fish captured in some years. However, native piscivore populations are decreasing. We evaluated trends in Asian carp and native piscivore populations over 15 years using data from a long-term monitoring program. Fast growth and patchy spatial distributions appear to reduce the vulnerability of Asian carp to predation, although reduced growth rates in recent years may increase the length of time they spend within the gape limits of native piscivores.
