Asia: Java, Indonesia. Clarias aff. batrachus from Indochina and Clarias aff. batrachus from Sundaland have been misidentified as Clarias batrachus from Java. Introduced elsewhere. Several countries report adverse ecological impact after introduction.

Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 0; Mjukstrålar i ryggfenan (totalt): 60-76; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 47 - 58. Body compressed posteriorly. Upper jaw a little projecting. Spine of pectoral fins rough on its outer edge and serrated on its inner edge (Ref. 4792). Occipital process more or less triangular, its length about 2 time in its width (Ref. 27732); distance between dorsal and occipital process 4-5.5 times in distance from tip of snout to end of occipital process (Ref. 43281). Genital papilla in males is elongated and pointed (Ref. 52012).

Biologi     Ordlista (t.ex. epibenthic)

Facultative air-breathing (Ref. 126274); Adults inhabit lowland streams (Ref. 57235), swamps, ponds, ditches, rice paddies, and pools left in low spots after rivers have been in flood (Ref. 2854, 57235). Usually confined to stagnant, muddy water (Ref. 1479). Found in medium to large-sized rivers, flooded fields and stagnant water bodies including sluggish flowing canals (Ref. 12975). Undertake lateral migrations from the Mekong mainstream, or other permanent water bodies, to flooded areas during the flood season and returns to the permanent water bodies at the onset of the dry season (Ref. 37770). Can live out of water for quite sometime and move short distances over land (Ref. 4833). Can walk and leave the water to migrate to other water bodies using its auxiliary breathing organs. The Lao use this fish as lap pa or ponne pa. Feed on insect larvae, earthworms, shells, shrimps, small fish, aquatic plants and debris (Ref. 6459). An important food fish (Ref. 4833) that is marketed live, fresh and frozen (Ref. 9987). Recently rare, being replaced by introduced African walking catfish (Ref. 57235).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

The pair manifests the 'spawning embrace' which is widely observed in other catfish species (Ref. 33313). The pair gently nudge each other in the genital region and flick their dorsal fins; male wraps his body around the female, then the female releases a stream of adhesive eggs into the nest (Ref. 44091). In southeast Asia, spawning period is during the rainy season, when rivers rise and fish are able to excavate nests in submerged mud banks and dikes of flooded rice fields (Ref. 40977).
