Asian Carp FAQs - 11 Found
An exponential increase in the population numbers of bighead and silver carp began in the mid-90s and continued through the mid-2000s in parts of the Mississippi and Illinois rivers. The Illinois Natural History Survey has estimated that a population of more than 4,000 silver carp (almost 10 tons) per mile exists between two Illinois River dams that limit their movement. USGS scientists hope to use genetic methods to determine the number of spawning Asian carp in different river reaches that are not bounded by dams.
