Grass carp is displayed in Srinagar.
A Kashmiri official for the Fisheries Department displays a grass carp brought from China to Kashmir's famous Dal Lake in Srinagar, in this picture taken on December 15, 2004. For years men and machines have toiled to clean up Kashmir's mirror-calm Dal Lake to remove choking weeds, lily pads and other water plants that have tarnished the image of the famed tourist attraction. But scientists in the Himalayan region have hit upon a new low-cost idea: flood the dying lake with thousands of weed-eating Chinese grass carp. Picture taken on December 15, 2004.
