> Siluriformes (Catfishes) > Clariidae (Airbreathing catfishes)
Etymology: Clarias:Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water. More on author: Günther.
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione Ecologia
Spine dorsali (totale) : 0. Distinguished from Southeast Asian congeners by an extremely short and rounded occipital process and by a very high dorsal fin. The combination of these characters are diagnostic for the species (Ref. 33566). Occipital process wide, broadly curved, with length 3-5 times in its width; distance between dorsal and occipital process 5-7 times in distance from tip of snout to end of occipital process (Ref. 43281). Body shape (shape guide): elongated.
Facultative air-breathing (Ref. 126274); Lives in lowland wetlands and rivers (Ref. 57235). Recorded as having been or being farmed in rice fields (Ref. 119549). Occurs in shallow, open water and is capable of lying buried in mud for lengthy period if ponds and lakes evaporate during dry seasons (Ref. 9987). Can move out of the water using its extended fins (Ref. 9987). Found in medium to large-sized rivers, stagnant water bodies including sluggish flowing canals and flooded fields of the Mekong (Ref. 12975). Spawns in small streams (Ref. 9987). Feeds on aquatic insects, young shrimps and small fishes (Ref. 6459). In Thailand, it was thought wrongly as female of Clarias batrachus (Ref 2686). Important foodfish and in pond cultures (Ref. 57235). Marketed live, fresh and frozen; consumed fried, broiled and baked (Ref. 9987). Cultivated on a small scale but attempts to farm it are increasing (Ref. 9987).

Resilienza (Fonte Biblio. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Assuming tm=1; Fec=800-14,000).
