With the specter of Asian carp looming, is there any hope for the Great Lakes? Maybe, according to this story in the Los Angeles Times.
A parasitic invasive species that fed on healthy trout, salmon and catfish had entered the Great Lakes through its shipping canals, quickly asserted its dominance, and pushed commercial and sport fishing industries to the brink. The sea lamprey, a razor-toothed, eel-like monster, attached itself to large fish and sucked the life out of them. In the 1940s, with no known predators and no clear road map to stop them, many feared the sea lamprey would take over the world's largest freshwater body. More than 50 years after biologists launched an all-out assault on the sea lamprey, the war is all but over. With science, money and muscle, biologists have reduced the sea lamprey population by 90% and restored the natural balance to the Great Lakes.
