Walking Catfish

The Walking Catfish can walk with its fins on land. The biggest we have in the Phuket Freshwater Fishing Lake is 8Kg.

Species Profile – Walking Catfish

The walking catfish, Clarias batrachus, is a species of freshwater airbreathing catfish found primarily in Southeast Asia, so named for its ability to “walk” across dry land, to find food or suitable environments. While it does not truly walk as most bipeds or quadrupeds do, it has the ability to use its pectoral fins to keep it upright as it makes a sort of wiggling motion with snakelike movements.[1] It can survive using this form of locomotion as long as it stays moist.[1] This fish normally lives in slow-moving and often stagnant waters in ponds, swamps, streams and rivers (Mekong and Chao Phraya basins), flooded rice paddies or temporary pools which may dry up. When this happens, its “walking” skill allows the fish to move to other sources of water.

Walking catfish are around 30 cm (a foot or so) in length and have an elongated body shape. Often covered laterally in small white spots, the body is mainly colored a gray or grayish brown.[2] This catfish has long-based dorsal and anal fins[2] as well as several pairs of sensory barbels. The skin is scaleless but covered with mucus, which protects the fish when it is out of water.

One main distinction between the walking catfish and native North American Ictalurid catfish is the walking catfish’s lack of an adipose fin.[2]

This fish needs to be handled carefully when fishing it out due to its hidden embedded sting or thorn-like defensive mechanism hidden behind its fins (including the middle ones before the tail fin, just like the majority of all catfish).

In the wild, the natural diet of this creature is omnivorous; it feeds on smaller fish, molluscs and other invertebrates as well as detritus and aquatic weeds. It is a voracious eater which consumes food rapidly and this habit makes it a particularly harmful invasive species.
