Indiana crews have finished installing a nearly 1,200-foot-long fence designed to prevent Asian carp from slipping into the Great Lakes through an Indiana marsh.
Construction of the 8-foot-tall chain-link fence was completed Tuesday at Eagle Marsh near Fort Wayne. Work on that fence and a 500-foot-long debris catch fence began in early September.
The fence is bolstered by almost 120 concrete barriers. It's designed to prevent adult carp from using the northeastern Indiana marsh to swim from the Wabash River system into the Maumee River and then onto Lake Erie during floods.
Biologists fear that if the carp reach the Great Lakes they could destroy its $7 billion-a-year fishing industry by starving out native species.
