In the news: Killer carp: In hiding or just a big fish tale?

From the Detroit Free Press:
As cleanup and Asian carp-searching efforts continued after a massive poisoning in the Chicago Sanitary and Ship Canal on Thursday, officials said they had found a lone Asian carp among the 200,000 pounds of dead fish.

The bighead carp, nearly 22 inches long, was found just above the lock and dam at Lockport.

That's one of many spots where DNA testing since July has shown the presence of carp.

The find is important because it established that the DNA testing is correct. That same testing has shown that there are carp just below an even more critical lock, the O'Brien lock, 7 miles from Lake Michigan.

A biologist who tested the poison on carp said Thursday that the fact that more carp weren't showing up dead in the canal wasn't surprising, since his tests showed they would sink to the bottom. Read more and watch video.
