Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 7; Raggi anali molli: 12 - 14; Vertebre: 44 - 46. Can be differentiated from its congeners by a unique combination of the following characters: head length 31.0-34.3% SL; dorsal to adipose distance 7.3-10.9% SL; length of dorsal-fin 27.3-30.8% SL; post-adipose distance 14.7-16.2% SL; interorbital distance 28.1-31.1% HL; presence of filamentous extensions on the first three dorsal-fin rays in adults (Ref. 38441). Depressed dorsal fin reaching adipose fin; adipose fin same color as body; body and fins a uniform dark brown; crenulate ridge along anterior edge of pectoral spine; 8 branched anal-fin rays (Ref. 12693). Elongated upper caudal lobe ending in a filament (Ref. 43281).

Inhabits slowly flowing or standing waters of the lower Mekong. Moves into flooded forests during periods of high water levels. Feeds on crustaceans and fishes. Marketed fresh (Ref. 12693).

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=0.00977 (0.00440 - 0.02172), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 38.5 [10.4, 172.2] mg/100g; Iron = 0.682 [0.270, 2.118] mg/100g; Protein = 16.2 [14.2, 18.2] %; Omega3 = 0.222 [0.097, 0.469] g/100g; Selenium = 55.6 [26.7, 120.9] μg/100g; VitaminA = 92 [18, 455] μg/100g; Zinc = 1.44 [0.99, 2.12] mg/100g (wet weight);
