Habitat and Ecology
It is Omnivore. Walking catfish are mainly active at night and prey on items such as insect larvae, fish eggs, fish and occasionally plant material. Commercial pond aquaculture of the catfish, Clarias batrachus (Linnaeus), commonly known as "pIa duk dan" in Thailand, "ikan lele" in Indonesia, and walking catfish in the U.S.A., first developed in Thailand in the late 1950s (Tamchalanukit et al. 1982, Areerat 1987). Its impact on introduction is largely unknown. In
Air breathing catfish (Clarias magur), attains maturity within the first years of life and normally spawns from April to August in both open and confined waters (Ahmed et al. 1985, Bhuiyan 1964, Chowdhury 1981). Talwar and Jhingran (1991) reported, that the C. batrachus spawn for short period just from July to August. In southeast Asia C. magur generally spawn during the rainy season, when rivers rise and fish are able to excavate nests in submerged mud banks and dykes of flooded rice fields. It breeds in shallow marginal waters of ponds, ditches and natural depressions, and inundated paddy-fields during summer monsoon and rainy season and attains a maximum length of 35 cm and a weight of 250 g (Chowdhury 1981). In Southeast Asia C. magur generally spawn during the rainy season, when rivers rise and fish are able to excavate nests in submerged mud banks and dikes of flooded rice fields. Culture practice in
They are commonly found in freshwater and brackish water. They can exist in cloudy, low-oxygen waters.
C. magur is abundant in ponds, rivers and in the mud they lie to concealed for hours. Found in all types of waters but more so in derelict and swampy waters. It can live out of water for quite some time and move short distances. This is a rather hardy fish. C. magur is widely distributed all over the
