Worries grow about a 'violent and destructive' invasive fish

The fish, weighing up to 100 pounds and eating 10% of their weight in algae every day, could pose an existential threat to the Great Lakes.
The behemoth exotic fish known as Asian carp have marched toward the Great Lakes for more than 25 years, but so far preventive efforts have kept the long-feared invasion of the prolific species at bay.
Officials in Michigan and Illinois would really love to keep it that way. But a standoff with the federal government is slowing plans down, while some urge immediate action to stay ahead of the fish.
The states are part of a multi-state and international coalition bent on keeping the voracious fish out of the region’s waterways. The fear is that the fish – weighing up to 100 pounds and eating 10% of their weight in algae every day – could alter ecosystems and collapse recreational and commercial fishing throughout the Great Lakes.
However, progress on a long-planned project to build an elaborate multi-layered system to prevent the advance of the invaders has slowed to a halt with no definite end in sight.
“If this fish ever becomes commonplace in the Great Lakes, it will destroy it as a fishery and change it forever,” Sen. Dick Durbin, D-Illinois, said on the Senate Floor on March 11.
