deskripsi pendek Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)): 2; duri punggung lunak (Keseluruhan (total)): 7-8; Sirip dubur lunak: 35; vertebrata, bertulang belakang: 48. Body without stripes; posterior nostril located near anterior nostril; 7 branched dorsal-fin rays; gill rakers rudimentary or absent; fins grey, never black (Ref. 12693). The center of the eye above the horizontal line through the mouth angle in juveniles; eye totally below the level of mouth angle in subadults and adults. The maxillary and mandibulary pairs of barbels well developed in juveniles; mandibulary barbels become rudimentary in subadults and adults (Ref. 9448). Gigantic size; oral teeth and gill rakers present in small juveniles, absent at about 30-50 cm SL; dorsal, pelvic and pectoral fins without filamentous extensions (Ref. 43281). Distinguished from other large catfish in the Mekong by its lack of teeth and the almost complete absence of barbels (Ref. 2686)

Biologi     Daftar kata (contoh epibenthic)

Facultative air-breathing (Ref. 126274); A migratory species (Ref. 37772) which occurs in medium to large-sized rivers (Ref. 12975). Feeds on detritus and algae on the bottom (Ref. 58784); feeds only on vegetation in the river but takes other food in captivity; little is known on its general pattern of life and migratory journeys for spawning (Ref. 2686). Shows one of the fastest growth rates of any fish in the world, reaching 150 to 200 kg in 6 years (Ref. 12693). Cited in the Guinness Book of Records as largest freshwater fish (Ref. 6472). Marketed fresh (Ref. 12693). Maximum length of 300 cm needs confirmation. Threatened due to over harvesting and habitat loss (Ref. 58490).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00386 - 0.01562), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.3   ±0.17 se; based on food items.
Generation time: 12.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Daya lenting (Ref. 120179):  Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Assuming tm=5-10).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (79 of 100).
kategori harga (Ref. 80766):   Unknown.
