Trichopodus mentum Lacepède (ex Commerson), 1801
|Taxonomic Source(s):||Kottelat, M. 2013. The fishes of the inland waters of southeast Asia: a catalogue and core bibiography of the fishes known to occur in freshwaters, mangroves and estuaries. Raffles Bulletin of Zoology Supplement No. 27: 1-663.|
Assessment Information [top]
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Smith, K. & Allen, D.J.|
This locally common fish is widespread and well adaptive to impounded waters, its popularity on foodfish and ornamental and obtained both from wild caught and cultured. This species is abundant in all suitable habitats, it is assessed as Least Concern.
Geographic Range [top]
|Range Description:||The species is widely distributed from the lower Mekong basin (Cambodia and Viet Nam) to the Mae Khlong in Thailand, and the Malay Peninsula and Indonesia (Java, Sumatra and Kalimantan (e.g., the Kapuas River; Kottelat and Widjanarti 2005). The species has been widely introduced to several countries for aquaculture purposes. Apparently absent in Sarawak and presence in Sabah may be due to relatively late introductions.|

Etymology: Osphronemus:Greek, osphra = smell + Greek, nema = filament; because of the olfactory organs (Ref. 45335). More on author: Lacepède.

Asia: probably limited to Sumatra, Borneo, Java, the Malay Peninsula, Thailand and Indochina (Mekong basin). Has been introduced to several countries for aquaculture purposes. Apparently absent in Sarawak and presence in Sabah may be due to relatively late introductions.

Short description Morphology | Morphometrics
Dorsalspines (total): 12 - 14; Dorsalsoft rays (total): 10-13; Analspines: 9-13; Analsoft rays: 18 - 21; Vertebrae: 30 - 31. With 8-10 complete dark vertical bars in juvenile color phase; adults without vertical bars or sexual dichromatism, both sexes drab; transverse scale rows usually 6.1.12; dorsal fin spines usually 12-13 (rarely 11 or 14); soft-rayed portion of anal fin greatly enlarged, its distal margin parallel to distal margin of caudal fin; caudal fin rounded or obtusely rounded, not truncate or emarginate (Ref. 7425). Pelvic fins with first soft ray prolonged into a thread-like tentacle reaching posteriorly to or beyond hind margin of caudal fin.
Inhabits swamps, lakes and rivers (Ref. 9987), among vegetation (Ref. 56749). Enters flooded forest (Ref. 9497). Found in medium to large rivers and stagnant water bodies including sluggish flowing canals (Ref. 12975). Omnivorous. Feeds on both plants and animals such as some aquatic weeds, fish, frogs, earthworms and sometimes dead animals (Ref. 6459). Can breathe moist air, so can be kept alive for long periods out of water, making it possible to distribute it in areas lacking a cold chain (Ref. 9987). Was reported from miocene deposits in Central Sumatra (Ref. 7426). Utilized fresh and eaten steamed, pan-fried and baked (Ref. 9987).

Makes nests of bubbles in which the eggs and larvae float, protected by the male (Ref. 9987).
