Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 26 - 30. Differs from all other mastacembelids found in Myanmar and Thailand in having body with a series of very regular, oblique, dark bars, each with a narrow extension extending partially or entirely across abdomen, and having ripe females with a very elongate genital papillae (Ref. 39392).

Occurs in streams to peats (Ref. 57235). Found in medium to large-sized rivers and flooded fields (Ref. 12975). Nocturnal, feeding on invertebrates and small fishes (Ref. 13371). Commonly seen in aquarium trades and fish markets (Ref. 57235).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00407 (0.00251 - 0.00660), b=3.00 (2.86 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.0 ±0.61 se; based on food items.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
