Invasive Species
A discussion of the impact of invasive species in the Illinois River, including Grass Carp brought from East Asia; Rusty Crayfish from the southern United States which are displacing common crayfish; Common Carp, which arrived in 1831 and uproot underwater plants; Bighead Carp, arriving in the 1970s, eat large amounts of phytoplankton and aquatic insects; Water Flea from southeast Asia and Africa, a crustacean that is too large to be eaten by larval fish and may be a threat to native plankton; zebra mussels; round gobies; and of course Asian Carp.
