Biology     Glossary (e.g. epibenthic)

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

Phylogenetic diversity index (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).
Trophic level (Ref. 69278):  2.8   ±0.27 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (56 of 100).
Price category (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.
