MEKONG GIANT CATFISH (Pangasianodon gigas)  (photo: Zeb Hogan) With recorded sizes of up to 10.5ft (3.2m) and 660lb (300kg), the Mekong’s giant catfish currently holds the Guinness Book of World Record’s position for the world’s largest freshwater fish.  Although research projects are currently ongoing, relatively little is known about this species. Historically, the fish has a natural range that reaches from the lower Mekong in Vietnam all the way to the northern reaches of the river in the Yunnan province of China, spanning almost the entire 4,800 km length of the river. In infancy, this species feeds on zooplankton in the river and is known to be cannibalistic. After approximately one year, the fish becomes herbivorous, feeding on filamentous algae probably ingesting larvae and periphyton accidentally. The fish likely obtain their food from algae growing on submerged rocky surfaces, as they do not have any sort of dentition.
