Congress to seek more money to fight Asian carp

From poisons to nets to electric jolts, authorities are studying a series of desperate measures to ward off an invasion of the Great Lakes by hefty, hungry Asian carp.

More than a dozen members of Congress from the region agreed Wednesday to seek $20 million for developing ways to prevent the carp from becoming established in the lakes and jeopardizing the fishing industry by starving out competitors such as salmon and walleye.
