Mekong river catfish

With a length of up to 3.2 m and weight up to 300 kg, catfish is one of the largest freshwater fish species in the world. Scientists have only known this fish since 1930 when it was discovered at a fish market in Phnom Penh (Cambodia) and so far there has not been much research on fish.

Catfishes in Mekong have large and flat heads, wide mouth with two long antennae in the upper jaw, pelvic fins long to the caudal fin, small dorsal fins in the front. The back of the fish is in dark brown and the color of the abdomen and the fins is a bit lighter.

The main food for catfish is zooplankton, juveniles, fibrous algae, and accidentally some ingest larvae. Because these fish do not have teeth, they are capable of obtaining food from algae grown on submerged rock surfaces.

Catfish naturally lives in the Mekong basin in Vietnam to the north of the river in China’s Yunnan province. However, due to many different threats, catfish have migrated and lived in wider dispersion. Now people only see them appear in the middle of the Mekong River. They often gather at the beginning of the rainy season and migrate upstream to breed, and often live in the main river branches with a depth of 10 m or more. For now, you might be amazed at how big and special Mekong river fish species are, right? Wait for the next giant fish instructed following.

Flagfish in Mekong

Flagfish or Pla Thepa fish can reach a mass of 200 kg, while their greatest body length is 3 m. Distributed in the lower Mekong River, flagfish can be found in China and Myanmar regions. You can find both groups of young and adult fish remain in the Mekong mainstream and possibly in large tributaries without any of them in flooded areas. Although in 1996, scientists stated that these species live commonly in the middle of the Mekong River; now this fish is quite rare in all the river. They are even listed as a rare species in the IUCN Red List.

This fish is a meat-eater type with its food mainly being fish and crustaceans. It is believed that they live all year round in the Mekong mainstream because their food sources are aquatic animals living in the bottom water.

According to the fishermen, during the dry season, adult fish will usually stay in the deep part of the river. They only move out from these part during short hunting times when other small fish migrate through its area.
