In less than a decade since escaping Arkansas fish farms during late 1990s flooding, the hardy and voracious carp have come to dominate sections of the Mississippi River and its tributaries.
The leaping fish are silver and bighead carp, two closely related Asian carp species, that jump haphazardly when alarmed by passing boats and have injured boaters, and wiped out many native species.
The only barriers between these foreign invaders and our Great Lakes, are a few miles of waterway and a little-tested underwater electrical field spanning a canal near Chicago. The irony is the barrier was first proposed to keep round gobies from colonizing the Mississippi River watershed, but by the time the barrier was built they had already passed it.
Some Great Lakes Sportsmen advocate killing the carp in a long stretch of the river to give some breathing room to find a more permanent solution.
Scientists believe the carp could set off an ecological collapse in the lakes, ruining the primarily recreational $5 billion fishery and posing a threat to water quality for millions of people.In less than a decade since escaping Arkansas fish farms during late 1990s flooding, the hardy and voracious carp have come to dominate sect...all »In less than a decade since escaping Arkansas fish farms during late 1990s flooding, the hardy and voracious carp have come to dominate sections of the Mississippi River and its tributaries.
