Scientists are stepping up their search for methods to prevent Asian carp from becoming established in the Great Lakes, where they could threaten the fishing and boating industries.
Leon Carl of the U.S. Geological Survey told a U.S. Senate panel Thursday that researchers are looking at short- and long-term strategies.
They include stopping carp from spawning in rivers that flow into the lakes and developing poisons that would kill Asian carp but not other fish.
Carl said his staff scientists realize they need answers soon.
He testified in Washington before the Senate’s Water and Power Subcommittee.
The panel’s chairwoman, Sen. Debbie Stabenow of Michigan, said the government needs a quicker schedule for deciding how to separate the lakes from the Mississippi River basin.
