TRAVERSE CITY, Mich. (AP) — The U.S. Army Corps of Engineers has added three
options to list of possible measures for preventing Asian carp and other
invasive species from migrating between the Great Lakes and Mississippi
In December, the corps released a draft report suggesting methods such as
overfishing, ultraviolet light, water guns and introducing native predators
in Chicago-area rivers and canals that link the two massive aquatic systems.
A final version issued last week also raised the possibility of freezing or
drying sections of the waterways, or zapping organisms with carbon dioxide
pellets. Next, the corps will decide which options merit further
The report is
part of a series as officials develop a strategy for halting species
invasions of the Great Lakes, possibly including permanent separation of the
two drainage basins.
