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 River watersheds.

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 consideration.

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.
