The world's largest catfish, the Mekong giant catfish, gets its name from its most common habitat - the Mekong river. Its scientific name is Pangasianodon gigas.

Back in 2005, this fish held a record in the Guinness World Records, as the largest freshwater fish in the world.

As the fish grow up, interesting changes take place in their intrinsic characteristics. The young catfishes prey upon zooplankton, they even show cannibalistic traits. However, as they grow up, the toothless creature becomes completely herbivorous. They feed upon algae and plants in the river.

No aggressiveness has ever been observed in their nature. The adults live in deep waters, as compared to the young members of the species.

Sadly, the population of this species is decreasing rapidly. They have been listed as Critically Endangered species. The main threats behind their decreasing population are said to be the construction of dams, habitat destruction, navigation projects, overfishing, and pollution. Several efforts have been made to control the fishing of the giant catfish. The government of Thailand, along with the fishing community, are making efforts to bring positive changes. They are also putting efforts into restoring the fish population in freshwater rivers, including the Mekong River.

Dr. Hogan, an ecologist, has spent more than 20 years researching this fish. According to him, this fish symbolizes the health and integrity of the Mekong River.
