In the Great Lake, Asian Carp were introduced to the waterways to control nuisance algae blooms and aquatic vegetation in aquaculture facilities, farm ponds and sewage lagoons. These carp are incredible eaters.
This relationship worked well until Mother Nature and a few unsuspecting humans got in the way. Flood events helped carp escape from private ponds and aquaculture facilities
and human activities such as live bait releases, intentional stocking (to create a food source), and the construction of man-made canals helped these fishy fugitives on their path
to freedom. Once loose, Asian carp spread quickly, reproduced rapidly, and became very VERY abundant.

The native fish will move to a different area.
The carp's population will decrease due to increased breeding of the native species
The trophic level below the carp will thrive
The ecosystem will destabilize due to a competition for resources
