| Impact Description | There was diet substantial overlap of Bighead and Silver Carps with Gizzard Shad and less overlap with Bigmouth Buffalo in the Illinois and Mississippi rivers. No overlap with paddlefish. Although there was little evidence that bighead and silver carp were reducing zooplankton abundance, results did not rule out the possibility that these species could limit food resources for native fishes as the populations of bigheaded carp continue to increase in the Illinois and Mississippi rivers. |
