Biology     Glossary (e.g. epibenthic)

Adults are found in quiet, shallow (0.5-1.5 m), often muddy water, in sandy streams, rivers and tanks (Ref. 6028). Also occur in canals, beels and inundated fields (Ref. 1479). Feed on vegetable matter and fish (Ref. 6028).

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=0.00575 (0.00482 - 0.00687), b=3.03 (2.98 - 3.08), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.4 se; based on diet studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 153 [66, 276] mg/100g; Iron = 0.647 [0.339, 1.251] mg/100g; Protein = 16 [14, 18] %; Omega3 = 0.129 [0.054, 0.319] g/100g; Selenium = 28.5 [8.8, 96.4] μg/100g; VitaminA = 90.8 [15.2, 388.3] μg/100g; Zinc = 0.823 [0.552, 1.301] mg/100g (wet weight); based on nutrient studies.
