Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 33 - 40; Dorsale zachte stralen (totaal) : 67 - 82; Anale zachte stralen: 67 - 83; Wervels: 87 - 98. Body dull brown with 1-3 darker, longitudinal zigzag lines, more or less connected to form a reticulated pattern, more or less distinct and restricted to the dorsal two thirds of the body (Ref. 27732).

Adults live in highland streams to lowland wetlands (Ref. 57235). Usually found in streams and rivers with sand, pebble, or boulder substrate. They seldom leave the bottom except when disturbed. Also occur in still waters, both in coastal marshes and dry zone tanks. Sometimes stays partially buried in fine substrate. Enter flooded forest (Ref. 9497). Reported to occur in areas with rocky bottoms in the Mekong mainstream during the dry season, but enter canals, lakes and other floodplain areas during the flood season (Ref. 37770). Forages at night on benthic insect larvae, worms and some submerged plant material (Ref. 12693). Common during the summer months. Marketed fresh and frequently seen in the aquarium trade (Ref. 12693). Economic important species, both food and aquarium trades (Ref. 57235).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00276 - 0.00501), b=2.91 (2.82 - 3.00), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.8 ±0.27 se; based on food items.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).

Prijsklasse (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 261 [124, 515] mg/100g; Iron = 1.88 [0.89, 3.98] mg/100g; Protein = 17.4 [15.6, 19.2] %; Omega3 = 0.126 [0.064, 0.232] g/100g; Selenium = 22.6 [8.4, 64.1] μg/100g; VitaminA = 14.9 [5.4, 38.0] μg/100g; Zinc = 1.19 [0.67, 2.32] mg/100g (wet weight); based on nutrient studies.
