white sturgeon

9-year-old British boy caught a white sturgeon weighing nearly 300 kg on a fishing trip with his father in Fraser River, Canada.

Jeremy Wade, the River Monster TV host, has an impressive collection of 127 kg stingrays, human-eating catfish, giant piranhas and transsexuals.

Many Mekong and Asian fish species are among the world's largest freshwater fish species, but they are also at risk of extinction.
