Actinopteri (ray-finned fishes) > Siluriformes
(Catfishes) > Bagridae
Etymology: Mystus: Greek, mystax = whiskered, used by Belon in 1553 to describe all fishes with whiskers (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 6.5 - 7.2; dH range: 10 - 20; potamodromous (Ref. 51243); depth range - m (Ref. ), usually - m (Ref. ). Tropical; 22°C - 25°C (Ref. 2060)
Asia: Chao Phraya and Mekong basins. Rare throughout its range (Ref. 10418). Reported from Maeklong River (Ref. 26336).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 24.0 cm SL male/unsexed; (Ref. 30857)
soft rays: 10;
Vertebrae: 43. Distinguished from all other Mystus (indeed, from all other Asian Bagridae except Bagrichthys hypselopterus) by its extraordinary high dorsal fin, involving great elongation of the non-serrate dorsal fin spine and first three or four soft rays. Within Mystus sensu stricto, mouth relatively narrow (Ref. 10418).
Occur in medium to large-sized rivers (Ref. 12975). Adults feed on crustaceans and benthic invertebrates. Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). Usually marketed fresh (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.44 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Vulnerability (Ref. 59153
): Moderate vulnerability (40 of 100) .
