China will implant high-tech identification tags into all its captive pandas in an effort to better monitor the population and prevent inbreeding, media reports.

"Information about pedigree, age and other basic data will be permanently incorporated into the giant pandas by ways of molecular labelling or hypodermic implantation of sensing chips," said a State Forestry Administration official.

The tagging would begin this year, and would also help keep track of the animals once they are sent back into the wild, said the official, who was not identified.

At the end of 2004, China had 163 pandas in captivity and an estimated 1,590 in the wild.
