Giant Barb

Photo: Cambodian boy with giant barb
A boy poses with a giant barb on the Tonle Sap River near Phnom Penh, Cambodia. The fish, landed as bycatch by a local fishing operation, was tagged and released as part of a study of large freshwater species in the Mekong River Basin. There is evidence that giant barb once reached sizes of 10 feet (3 meters) long and 660 pounds (300 kilograms), but today specimens even half that size are extremely rare.
