Asian carp were first introduced into the southern United States in
the early 1970s to remove algae from farmed catfish ponds. Flooding
in the early 1900s caused many of the catfish farm ponds to
overflow, and Asian carp were released into local waterways in the
Mississippi River basin. The carp have since migrated northward up
the Mississippi River, becoming the most abundant species in some
areas of the River. Asian carp are of particular concern to the
Great Lakes region because of the potential harm they could cause
to the native ecosystem. Asian carp currently present in the
Mississippi River physically lack a stomach, so they must
continually feed on aquatic vegetation. Native fish species have
difficulty competing with Asian carp because of their rapid
consumption of resources. This book provides an overview and
background of the threat of Asian carp migrating into the Great
Lakes and what can be done to avoid this threat.
