Invasive fish species impact our aquatic ecosystems by competing with native fishes for food and habitat, altering food webs, and preying on sport fish eggs and larvae populations. Invasive fish can be introduced and spread in a variety of ways including ballast water, movement of bait, the aquarium and water garden trades, live food fish, unauthorized introductions, and canals and water diversions.
