Chapter 4: Community & Population Ecology
Asian carp jump out of the water in response to electrofishing. The Asian carp in the inset photograph were harvested from the Little Calumet River in Illinois in May, 2010, using rotenone, a toxin often used as an insecticide, in an effort to learn more about the population of the species (credit main image: modification of work by USGS; credit inset: modification of work by Lt. David French, USCG).
