World's Largest Feshwater Fish Feared Extinct

Say good-bye to the Chinese paddlefish. The 1,000-pound fish has not been seen since 2003, and no juevenile fish have been spotted in more than ten years. Scientists now believe that the species is likely extinct.

The paddlefish was fairly plentiful through the 1970s. Then came 1983's constructino of the Gehzouba hydroelectric dam on the Yangtze River, followed more recently by the Three Gorges Dam. The dams effectively destroyed the paddlefish's migratory routes, cut them off from their spawning grounds, and killed any chance the great fish had for survival.
