| Impact Description | Ctenopharyngodon idella is known to out-compete native species for both food and habitat. Research in small closed systems has demonstrated that due to grass carp’s preference for native aquatic plants over milfoil, these fish compete with waterfowl, which feed on these plants as well. |
