Chinese sturgeons with micro chips

1,512 endangered Chinese sturgeons implanted with microchips were released into the Yangtze River a few days back as part of a project to study their migration habits. Main intention is to ascertain where the fish live and spawn. Information gathered could be used to devise more effective conservation plans.
Dam construction on the river is believed to have decimated numbers of sturgeon, which gather at the mouth of the Yangtze each spring to swim to spawning grounds upstream
The prehistoric fish are believed to be on the verge of extinction. Xie Yumin, Director of the Shanghai Wildlife Conservation Administration Office, is heading the project. Each fish carries a tag with a phone number to call in the event it is caught or trapped
