Risk of invasion by Asian carp
As scientists aboard a research vessel triggers an electrical current, calm river turns into a seething mass of Illinois, silver. Asian carp by the dozen on the water as if shot from a pistol released, the rise in graceful arcs before they are below the surface with little extras like geysers. Water quality specialists from Thad Cook growls like a whopper belt him in the stomach. His colleagues duck and dodge to fish with rocket plop like to avoid on the cover, winds like crazy to pick someone the slimy creatures, kite flying and surfing can overboard.
It's like a scene from a Hitchcock movie - and actually fly carp have a dubious role in more than a YouTube video player. Biologists, however, fear that may be a different kind of horror story to take shape under water: the importance of a war for survival between the aggressive newcomers from Asia tent and native species, people, to catch the fish or make life fun. "We suspect that at some point it is but a drop to be on the populations of some of these native fish," John Chick, an aquatic ecologist with the Great Rivers National Center and Education Center, said on the Mississippi River near St. . Louis.
